BOSTON—A pair of preclinical studies suggest the FLT3/BTK inhibitor CG’806 is active in a range of hematologic malignancies.

In one of the studies, CG’806 proved particularly effective against acute myeloid leukemia (AML) cells harboring mutant forms of FLT3, and the compound was able to eradicate AML in mice.

In another study, researchers found CG’806 exhibited “broad potency” against leukemias, lymphomas, myelodysplastic syndromes (MDS), and myeloproliferative neoplasms (MPNs).

Both studies were presented as posters at Hematologic Malignancies: Translating Discoveries to Novel Therapies (poster 25 and poster 44).

Both studies involved researchers from Aptose Biosciences, the company developing CG’806.

Poster 25

Weiguo Zhang, MD, PhD, of The University of Texas MD Anderson Cancer Center in Houston, and his colleagues presented poster 25, “CG’806, a first-in-class FLT3/BTK inhibitor, exerts superior potency against AML cells harboring ITD, TKD and gatekeeper mutated FLT3 or wild-type FLT3.”

The researchers tested CG’806 and other FLT3 inhibitors in human or murine leukemia cell lines with wild-type (WT) FLT3, FLT3-ITD mutations, FLT3 TKD domain mutations, or ITD plus TKD mutations.

Compared to second-generation FLT3 inhibitors (quizartinib, gilteritinib, or crenolanib), CG’806 showed more pronounced anti-proliferative effects in leukemia cells with ITD mutations, D835 mutations, ITD plus F691I/Y842D/D835 mutations, or in FLT3 WT cells.

With CG’086, the IC50s in human AML cell lines were 0.17 nM for MV4-11 (FLT3-ITD) and 0.82 nM for MOLM13 (FLT3-ITD).

The IC50s in the murine leukemia cell lines were 9.49 nM for Ba/F3 (FLT3-WT), 0.30 nM for Ba/F3 (FLT3-ITD), 8.26 nM for Ba/F3 (FLT3-D835Y), 9.72 nM for Ba/F3 (FLT3-ITD+D835Y), and 0.43 nM for Ba/F3 (FLT3-ITD+F691L).

The researchers also found that CG’806 “triggers marked apoptosis” in FLT3-ITD-mutated primary AML samples but minimal apoptosis in normal bone marrow cells.

Another finding was that once-daily oral dosing of CG’806 in a murine model of AML (MV4-11) resulted in sustained micromolar plasma concentration over a 24-hour period.

This was accompanied by complete elimination of AML FLT3-ITD tumors without toxicity, the researchers said.

Poster 44

Stephen E. Kurtz, PhD, of Oregon Health & Science University in Portland, and his colleagues presented poster 44, “CG’806, a First-in-Class FLT3/BTK Inhibitor, Exhibits Potent Activity against AML Patient Samples with Mutant or Wild-Type FLT3, as well as Other Hematologic Malignancy Subtypes.”

The researchers tested CG’806 in samples from patients with AML (n=82), MDS/MPNs (n=15), acute lymphoblastic leukemia (ALL, n=17), chronic lymphocytic leukemia (CLL, n=58), and chronic myeloid leukemia (CML, n=4).

The team observed “broad sensitivity” to CG’806, with 59% (48/82) of AML, 53% (8/15) of MDS/MPN, 40% (23/58) of CLL, 29% (5/17) of ALL, and 25% (1/4) of CML cases exhibiting an IC50 of less than 100 nM.

Among the 38 tested AML samples with known FLT3 mutational status, the FLT3-ITD+ AML samples tended to have enhanced sensitivity to CG’806 (median IC50 = 20 nM, n=8) relative to the FLT3-WT samples (median IC50 = 120 nM, n=30).

The researchers also found that CG’806 exerted potent anti-proliferative activity against human AML, B-ALL, mantle cell lymphoma, Burkitt lymphoma, and diffuse large B-cell lymphoma cell lines.

“The analyses of CG’806 against primary hematologic malignancy patient samples and cultured cell lines show evidence of potent and broad drug activity in AML and other disease subtypes and support further development of this agent for hematologic malignancies,” Dr Kurtz said.

The European Commission (EC) has approved the anti-PD-1 therapy pembrolizumab (Keytruda) for use in patients with classical Hodgkin lymphoma (cHL).

The drug is now approved to treat adults with relapsed or refractory cHL who have failed autologous stem cell transplant (auto-SCT) and brentuximab vedotin (BV) or who are transplant-ineligible and have failed treatment with BV.

The approval allows marketing of pembrolizumab for this indication in the European Economic Area (EEA).

This is the first approval for pembrolizumab in a hematologic malignancy in the EEA. The drug was previously approved there as a treatment for melanoma and non-small-cell lung cancer.

The new approval for pembrolizumab was based on data from the KEYNOTE-087 and KEYNOTE-013 trials.

Results from KEYNOTE-013 were presented at the 2016 ASH Annual Meeting (abstract 1108), and results from KEYNOTE-087 were recently published in the Journal of Clinical Oncology.

KEYNOTE-087

In this phase 2 trial, researchers evaluated pembrolizumab (a 200 mg fixed dose every 3 weeks) in patients with relapsed or refractory cHL across 3 cohorts:

• Cohort 1: Patients who progressed after auto-HSCT and subsequent treatment with BV
• Cohort 2: Patients who failed salvage chemotherapy, were ineligible for a transplant, and progressed after BV
• Cohort 3: Patients who progressed after auto-HSCT and did not receive BV after transplant.

Across all 210 enrolled patients, the overall response rate (ORR) was 69.0%, and the complete response (CR) rate was 22.4%.

In Cohort 1 (n=69), the ORR was 73.9%, and the CR rate was 21.7%.

In Cohort 2 (n=81), the ORR was 64.2%, and the CR rate was 24.7%.

In Cohort 3 (n=60), the ORR was 70.0%, and the CR rate was 20%.

For the entire study cohort, the median duration of response was not reached, and the median overall survival (OS) was not reached. At 9 months, the OS was 97.5%, and the progression-free survival (PFS) was 63.4%.

The most common treatment-related adverse events (AEs) were hypothyroidism (12.4%), pyrexia (10.5%), fatigue (9.0%), rash (7.6%), diarrhea (7.1%), headache (6.2%), nausea (5.7%), cough (5.7%), and neutropenia (5.2%).

The most common grade 3/4 treatment-related AEs were neutropenia (2.4%), diarrhea (1.0%), and dyspnea (1.0%). Immune-mediated AEs included pneumonitis (2.9%), hyperthyroidism (2.9%), colitis (1.0%), and myositis (1.0%).

There were 9 discontinuations because of treatment-related AEs and no treatment-related deaths.

KEYNOTE-013

KEYNOTE-013 is a phase 1b trial that has enrolled 31 patients with relapsed or refractory cHL who failed auto-HSCT and subsequent BV or who were transplant-ineligible.

Patients received pembrolizumab at 10 mg/kg every 2 weeks. The median duration of follow-up was 29 months.

The ORR was 58%, and the CR rate was 19%. The median duration of response had not been reached at last follow-up (range, 0.0+ to 26.1+ months), and 70% of responding patients had a response lasting 12 months or more.

The median PFS was 11.4 months (range, 4.9-27.8 months). The 6-month PFS rate was 66%, and the 12-month PFS rate was 48%.

The median OS was not reached. Six-month and 12-month OS rates were 100% and 87%, respectively.

The most common treatment-related AEs were diarrhea (19%), hypothyroidism (13%), pneumonitis (13%), nausea (13%), fatigue (10%), and dyspnea (10%).

The most common grade 3/4 treatment-related AEs were colitis (3%), axillary pain (3%), AST increase (3%), joint swelling (3%), nephrotic syndrome back pain (3%), and dyspnea (3%).

AEs leading to discontinuation were nephrotic syndrome (grade 3), interstitial lung disease (grade 2), and pneumonitis (grade 2). There were no treatment-related deaths.

Lower-intensity radiation regimens for patients with early-stage Hodgkin lymphoma (HL) did not shorten progression-free survival (PFS), according to a long-term analysis. Further, for patients with unfavorable early-stage disease, a more intense chemotherapy or radiation regimen conferred no survival benefit.

The German Hodgkin Study Group included patients with early-stage HL who had both early-stage favorable HL and early-stage unfavorable HL. Stephanie Sasse, MD, and her study group colleagues published long-term follow-up findings from multiple trials, conducted from 1993 to 2003, that evaluated risk-adapted treatment strategies to reduce radiation field size and chemotherapy intensity, “aiming at achieving sufficient tumor control while potentially reducing treatment-associated toxicity,” wrote Dr. Sasse and her colleagues of the University Hospital of Cologne (Ger.) (J Clin Oncol. 2017 Apr 18. doi: JCO2016709410).

Trials in favorable HL

Of the 627 patients in the HD7 trial in patients with favorable HL, combined-modality therapy resulted in better rates of PFS (73%) over a 15-year period, compared with extended-field radiotherapy (RT) alone (52%) (hazard ratio, 0.5; 95% confidence interval, 0.3-0.6; P less than 0.001). Another study, called HD10, was in early-stage favorable HL patients. It compared a lower-intensity regimen of two cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) plus 20 Gy involved-field RT with a four-cycle ABVD regimen combined with 30 Gy involved-field RT. The 1,190-patient study achieved a median follow-up of 98 months, finding that the less-intense regimen was not inferior with an identical 10-year PFS of 87% in both arms (HR 1.0; 95% CI 0.6-1.5). Overall survival (OS) was nearly identical as well, at 94% in each arm (HR 0.9; 95% CI, 0.5-1.6).

Both trials HD7 and HD10 tracked the incidence of secondary neoplasias and detected no significant differences between groups, though there was a nonsignificant trend toward more secondary neoplasias for the HD7 patients who received extended-field radiotherapy. These analyses “strongly support the current risk-adapted treatment strategy in early-stage favorable HL,” wrote Dr. Sasse and her coinvestigators.

Trials in unfavorable HL

The HD8 trial enrolled 1,064 patients and followed them for a median 153 months to compare the efficacy of involved-field RT with extended-field RT, finding involved-field RT noninferior for PFS (HR, 1.0; 95% CI, 0.8-1.2). However, the overall 15-year PFS rate of 74% and OS rate of 82% “leave room for improvement,” said the investigators.

Finally, trial HD11 compared two different chemotherapy regimens and two different radiation doses. Patients received four cycles of either ABVD or bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone at baseline dosage (BEACOPP_baseline), followed by 20 or 30 Gy involved-field RT. The study, which followed 1,395 patients for a median of 106 months, had a 2x2 factorial design.

Following the HD11 cohort longitudinally showed that BEACOPP_baseline did not confer a PFS advantage over ABVD for patients receiving the 30 Gy RT regimen (HR 1.1; 95% CI, 0.7-1.5). Nor did patients who received 20 Gy RT have significantly longer PFS with the more intense BEACOPPbaseline chemotherapy regimen (HR 0.8; 95% CI, 0.6-1.1).

Overall survival and the incidence of secondary neoplasias did not differ between trial arms in HD11, said Dr. Sasse and her coinvestigators.

To further explore whether more intense chemotherapy might result in better PFS rates for patients with early-stage unfavorable HL, Dr. Sasse and her colleagues are following long-term results from more recent trial, HD14, that combined two cycles of BEACOPP_escalated and two cycles of ABVD. More short-term toxicity was seen, but patients in this trial arm have significantly better 5-year PFS rates than do those receiving four cycles of ABVD. “The improved tumor control is a relevant outcome parameter for patients,” wrote Dr. Sasse and her colleagues.

The investigators are reserving judgment about whether more radiation exposure and higher doses of alkylating agents and etoposide may eventually result in higher rates of secondary neoplasms. “Subsequent analyses with even longer follow-up will have to confirm that the reduction of RT field size or dose indeed translates into a reduced risk of [secondary neoplasms],” they wrote.

Several of the authors reported multiple relationships with pharmaceutical companies. The study was funded by a grant from the German Cancer Aid.

Of the 627 patients in the HD7 trial in patients with favorable HL, combined-modality therapy resulted in better rates of PFS (73%) over a 15-year period, compared with extended-field radiotherapy (RT) alone (52%) (hazard ratio, 0.5; 95% confidence interval, 0.3-0.6; P less than 0.001). Another study, called HD10, was in early-stage favorable HL patients. It compared a lower-intensity regimen of two cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) plus 20 Gy involved-field RT with a four-cycle ABVD regimen combined with 30 Gy involved-field RT. The 1,190-patient study achieved a median follow-up of 98 months, finding that the less-intense regimen was not inferior with an identical 10-year PFS of 87% in both arms (HR 1.0; 95% CI 0.6-1.5). Overall survival (OS) was nearly identical as well, at 94% in each arm (HR 0.9; 95% CI, 0.5-1.6).

Both trials HD7 and HD10 tracked the incidence of secondary neoplasias and detected no significant differences between groups, though there was a nonsignificant trend toward more secondary neoplasias for the HD7 patients who received extended-field radiotherapy. These analyses “strongly support the current risk-adapted treatment strategy in early-stage favorable HL,” wrote Dr. Sasse and her coinvestigators.

Trials in unfavorable HL

The HD8 trial enrolled 1,064 patients and followed them for a median 153 months to compare the efficacy of involved-field RT with extended-field RT, finding involved-field RT noninferior for PFS (HR, 1.0; 95% CI, 0.8-1.2). However, the overall 15-year PFS rate of 74% and OS rate of 82% “leave room for improvement,” said the investigators.

Finally, trial HD11 compared two different chemotherapy regimens and two different radiation doses. Patients received four cycles of either ABVD or bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone at baseline dosage (BEACOPP_baseline), followed by 20 or 30 Gy involved-field RT. The study, which followed 1,395 patients for a median of 106 months, had a 2x2 factorial design.

Following the HD11 cohort longitudinally showed that BEACOPP_baseline did not confer a PFS advantage over ABVD for patients receiving the 30 Gy RT regimen (HR 1.1; 95% CI, 0.7-1.5). Nor did patients who received 20 Gy RT have significantly longer PFS with the more intense BEACOPPbaseline chemotherapy regimen (HR 0.8; 95% CI, 0.6-1.1).

Overall survival and the incidence of secondary neoplasias did not differ between trial arms in HD11, said Dr. Sasse and her coinvestigators.

To further explore whether more intense chemotherapy might result in better PFS rates for patients with early-stage unfavorable HL, Dr. Sasse and her colleagues are following long-term results from more recent trial, HD14, that combined two cycles of BEACOPP_escalated and two cycles of ABVD. More short-term toxicity was seen, but patients in this trial arm have significantly better 5-year PFS rates than do those receiving four cycles of ABVD. “The improved tumor control is a relevant outcome parameter for patients,” wrote Dr. Sasse and her colleagues.

The investigators are reserving judgment about whether more radiation exposure and higher doses of alkylating agents and etoposide may eventually result in higher rates of secondary neoplasms. “Subsequent analyses with even longer follow-up will have to confirm that the reduction of RT field size or dose indeed translates into a reduced risk of [secondary neoplasms],” they wrote.

Several of the authors reported multiple relationships with pharmaceutical companies. The study was funded by a grant from the German Cancer Aid.

Lower-intensity radiation regimens for patients with early-stage Hodgkin lymphoma (HL) did not shorten progression-free survival (PFS), according to a long-term analysis. Further, for patients with unfavorable early-stage disease, a more intense chemotherapy or radiation regimen conferred no survival benefit.

The German Hodgkin Study Group included patients with early-stage HL who had both early-stage favorable HL and early-stage unfavorable HL. Stephanie Sasse, MD, and her study group colleagues published long-term follow-up findings from multiple trials, conducted from 1993 to 2003, that evaluated risk-adapted treatment strategies to reduce radiation field size and chemotherapy intensity, “aiming at achieving sufficient tumor control while potentially reducing treatment-associated toxicity,” wrote Dr. Sasse and her colleagues of the University Hospital of Cologne (Ger.) (J Clin Oncol. 2017 Apr 18. doi: JCO2016709410).

The immune checkpoint inhibitor pembrolizumab has good antitumor activity and a favorable safety profile when used to treat relapsed or refractory classic Hodgkin lymphoma, according to findings from the KEYNOTE-087 trial.

Pembrolizumab has garnered interest for this population because Hodgkin Reed-Sternberg cells have a chromosomal alteration leading to overexpression of both programmed death ligand 1 and programmed death ligand 2.

The anti-PD-1 therapy pembrolizumab could change the treatment paradigm of relapsed or refractory classic Hodgkin lymphoma (cHL), according to researchers.

In a phase 2 trial, pembrolizumab produced an overall response rate (ORR) of 69% and a complete response (CR) rate of 22% in adults with cHL who had failed treatment with brentuximab vedotin (BV), autologous hematopoietic stem cell transplant (auto-HSCT), or both.

The researchers said the safety profile of pembrolizumab was “acceptable” and largely consistent with safety in previous studies of the drug.

Twelve percent of patients temporarily stopped taking pembrolizumab due to treatment-related adverse events (AEs), and 4% stopped taking the drug entirely as a result of AEs.

Craig H. Moskowitz, MD, of Memorial Sloan Kettering Cancer Center in New York, New York, and his colleagues reported these results, from the KEYNOTE-087 trial, in the Journal of Clinical Oncology.

The trial was sponsored by Merck, the company that markets pembrolizumab as Keytruda.

In KEYNOTE-087, the researchers evaluated pembrolizumab (a 200 mg fixed dose every 3 weeks) in patients with relapsed or refractory cHL across 3 cohorts:

Cohort 1: Patients who progressed after auto-HSCT and subsequent treatment with BV

Cohort 2: Patients who failed salvage chemotherapy, were ineligible for a transplant, and progressed after BV

Cohort 3: Patients who progressed after auto-HSCT and did not receive BV after transplant.

Efficacy

Across all 210 enrolled patients, the ORR was 69.0%, and the CR rate was 22.4%.

In Cohort 1 (n=69), the ORR was 73.9%. The CR rate was 21.7%, the partial response (PR) rate was 52.2%, 15.9% of patients had stable disease (SD), and 7.2% progressed. In 82.2% of responders, the response lasted 6 months or more.

In Cohort 2 (n=81), the ORR was 64.2%. The CR rate was 24.7%, the PR rate was 39.5%, 12.3% of patients had SD, and 21.0% progressed. In 70.0% of responders, the response lasted 6 months or more.

In Cohort 3 (n=60), the ORR was 70.0%. Twenty percent of patients had a CR, 50.0% had a PR, 16.7% had SD, and 13.3% progressed. In 75.6% of responders, the response lasted 6 months or more.

Results also included an analysis of patients with primary refractory disease (n=73), which was defined as failure to achieve CR or PR with first-line treatment. In this patient population, the ORR was 79.5%.

An ORR of 67.8% was reported in patients who relapsed after 3 or more lines of prior therapy (99/146).

For the entire study cohort, the median duration of response was not reached, and the median overall survival was not reached. At 9 months, the overall survival rate was 97.5%, and the progression-free survival rate was 63.4%.

Safety

The most common AEs related to pembrolizumab were hypothyroidism (12.4%), pyrexia (10.5%), fatigue (9.0%), rash (7.6%), diarrhea (7.1%), headache (6.2%), nausea (5.7%), cough (5.7%), and neutropenia (5.2%).

The most common grade 3/4 treatment-related AEs were neutropenia (2.4%), diarrhea (1.0%), and dyspnea (1.0%). Immune-mediated AEs included pneumonitis (2.9%), hyperthyroidism (2.9%), colitis (1.0%), and myositis (1.0%).

Nine patients (4.3%) stopped taking pembrolizumab due to treatment-related AEs, including myocarditis, myelitis, myositis, pneumonitis, infusion-related reactions, and cytokine release syndrome.

Twenty-six patients (12.4%) had treatment interruptions due to pembrolizumab-related AEs.

Two patients died during follow-up, but neither death was considered related to pembrolizumab. One patient died of septic shock and the other of acute graft-versus-host disease.

Second cancers take a greater toll on patients under the age of 40, according to research published in JAMA Oncology.

Researchers studied 14 types of cancer occurring in more than 1 million patients.

For nearly all of the cancers studied, 5-year survival rates were much higher if the cancer occurred as a first malignancy rather than a second cancer.

These survival differences were more pronounced in pediatric patients and adolescents and young adults (AYAs) than they were in patients age 40 and older.

Researchers hope these findings will help guide clinicians in providing age-specific recommendations on cancer prevention, screening, treatment, and survivorship, especially among the AYA population.

“Although the increased incidence of second cancers is well known among cancer survivors, less is known about outcomes of these cancers or the influence of age,” said Theresa Keegan, PhD, of the UC Davis Comprehensive Cancer Center in Sacramento, California.

With this in mind, Dr Keegan and her colleagues analyzed data on patients diagnosed with either a single cancer or a first and second malignancy during 1992 through 2008. The researchers used Surveillance, Epidemiology and End Results program data collected from 13 cancer registries.

The team collected data on the 14 most common cancer types that affect AYAs: acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), Hodgkin lymphoma (HL), non-Hodgkin lymphoma (NHL), soft tissue sarcoma, and bone sarcoma, as well as female breast, thyroid, testicular, colorectal, central nervous system, cervical, and ovarian cancers.

There were a total of 15,954 pediatric patients (younger than 15 years at diagnosis), 125,750 AYAs (ages 15 to 39), and 878,370 older adult patients (age 40 and older).

Survival rates

For pediatric patients, the 5-year relative survival was 80% for a first cancer and 47% for a second primary malignancy.

For AYAs, the 5-year relative survival was 81% for a first cancer and 60% for a second primary malignancy.

For older adults, the 5-year relative survival was 70% for a first cancer and 61% for a second primary malignancy.

When the researchers looked at 5-year survival by age and individual cancer types, they found striking differences depending on whether it was a first or second malignancy in all but 2 of the 14 cancer types, testicular cancer and melanoma.

“For almost every type of cancer, the AYA population did worse with a secondary cancer,” said study author Melanie Goldfarb, MD, of John Wayne Cancer Institute at Providence Saint John’s Health Center in Santa Monica, California.

“What struck us was that the second cancer caused such an increased risk of death.”

Lymphomas

For pediatric patients with HL, the 5-year relative survival was 95% when patients had HL as a first cancer. There were no data on HL as a second primary malignancy.

For AYAs, the 5-year relative survival was 93% when patients had HL as a first cancer and 72% when they had HL as a second primary malignancy.

For older adults, the 5-year relative survival was 69% when patients had HL as a first cancer and 54% when they had HL as a second primary malignancy.

For pediatric patients with NHL, the 5-year relative survival was 84% when patients had NHL as a first cancer and 63% when they had NHL as a second primary malignancy.

For AYAs, the 5-year relative survival was 64% when patients had NHL as a first cancer and 22% when they had NHL as a second primary malignancy.

For older adults, the 5-year relative survival was 57% when patients had NHL as a first cancer and 54% when they had NHL as a second primary malignancy.

Leukemias

For pediatric patients with ALL, the 5-year relative survival was 87% when patients had ALL as a first cancer and 63% when they had ALL as a second primary malignancy.

For AYAs, the 5-year relative survival was 48% when patients had ALL as a first cancer and 26% when they had ALL as a second primary malignancy.

For older adults, the 5-year relative survival was 17% when patients had ALL as a first cancer and 11% when they had ALL as a second primary malignancy.

For pediatric patients with AML, the 5-year relative survival was 57% when patients had AML as a first cancer and 29% when they had AML as a second primary malignancy.

For AYAs, the 5-year relative survival was 46% when patients had AML as a first cancer and 23% when they had AML as a second primary malignancy.

For older adults, the 5-year relative survival was 12% when patients had AML as a first cancer and 10% when they had AML as a second primary malignancy.

Why younger patients tend to fare worse after a second cancer than older patients is not fully understood or specifically addressed in the current study, the researchers noted.

Now, the team plans to examine how the time between getting a first and second cancer affects survival and whether the type of treatment for the first cancer influences the outcome of a second cancer.

Second cancers take a greater toll on patients under the age of 40, according to research published in JAMA Oncology.

Researchers studied 14 types of cancer occurring in more than 1 million patients.

For nearly all of the cancers studied, 5-year survival rates were much higher if the cancer occurred as a first malignancy rather than a second cancer.

These survival differences were more pronounced in pediatric patients and adolescents and young adults (AYAs) than they were in patients age 40 and older.

Researchers hope these findings will help guide clinicians in providing age-specific recommendations on cancer prevention, screening, treatment, and survivorship, especially among the AYA population.

“Although the increased incidence of second cancers is well known among cancer survivors, less is known about outcomes of these cancers or the influence of age,” said Theresa Keegan, PhD, of the UC Davis Comprehensive Cancer Center in Sacramento, California.

With this in mind, Dr Keegan and her colleagues analyzed data on patients diagnosed with either a single cancer or a first and second malignancy during 1992 through 2008. The researchers used Surveillance, Epidemiology and End Results program data collected from 13 cancer registries.

The team collected data on the 14 most common cancer types that affect AYAs: acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), Hodgkin lymphoma (HL), non-Hodgkin lymphoma (NHL), soft tissue sarcoma, and bone sarcoma, as well as female breast, thyroid, testicular, colorectal, central nervous system, cervical, and ovarian cancers.

There were a total of 15,954 pediatric patients (younger than 15 years at diagnosis), 125,750 AYAs (ages 15 to 39), and 878,370 older adult patients (age 40 and older).

Survival rates

For pediatric patients, the 5-year relative survival was 80% for a first cancer and 47% for a second primary malignancy.

For AYAs, the 5-year relative survival was 81% for a first cancer and 60% for a second primary malignancy.

For older adults, the 5-year relative survival was 70% for a first cancer and 61% for a second primary malignancy.

When the researchers looked at 5-year survival by age and individual cancer types, they found striking differences depending on whether it was a first or second malignancy in all but 2 of the 14 cancer types, testicular cancer and melanoma.

“For almost every type of cancer, the AYA population did worse with a secondary cancer,” said study author Melanie Goldfarb, MD, of John Wayne Cancer Institute at Providence Saint John’s Health Center in Santa Monica, California.

“What struck us was that the second cancer caused such an increased risk of death.”

Lymphomas

For pediatric patients with HL, the 5-year relative survival was 95% when patients had HL as a first cancer. There were no data on HL as a second primary malignancy.

For AYAs, the 5-year relative survival was 93% when patients had HL as a first cancer and 72% when they had HL as a second primary malignancy.

For older adults, the 5-year relative survival was 69% when patients had HL as a first cancer and 54% when they had HL as a second primary malignancy.

For pediatric patients with NHL, the 5-year relative survival was 84% when patients had NHL as a first cancer and 63% when they had NHL as a second primary malignancy.

For AYAs, the 5-year relative survival was 64% when patients had NHL as a first cancer and 22% when they had NHL as a second primary malignancy.

For older adults, the 5-year relative survival was 57% when patients had NHL as a first cancer and 54% when they had NHL as a second primary malignancy.

Leukemias

For pediatric patients with ALL, the 5-year relative survival was 87% when patients had ALL as a first cancer and 63% when they had ALL as a second primary malignancy.

For AYAs, the 5-year relative survival was 48% when patients had ALL as a first cancer and 26% when they had ALL as a second primary malignancy.

For older adults, the 5-year relative survival was 17% when patients had ALL as a first cancer and 11% when they had ALL as a second primary malignancy.

WASHINGTON, DC—New research suggests HIV-positive adults in the US will see a shift in cancer risk and burden in the coming years.

The study indicates that, through 2030, people living with HIV will see a decrease in AIDS-defining cancers, such as non-Hodgkin lymphoma (NHL) and Kaposi sarcoma.

But this group will also see an increase in cancers not linked to AIDS, such as prostate and liver cancers.

Researchers made these projections in a presentation at the AACR Annual Meeting 2017 (abstract 5302).

“Declines in cancer incidence rates, particularly for AIDS-defining cancers, are likely driven by widespread treatment with modern antiretroviral therapies, which reduce immune suppression and decrease risk of some cancers,” said Jessica Y. Islam, a doctoral student at the University of North Carolina Gillings School of Global Public Health in Chapel Hill.

She and her collaborators estimated future cancer risk and burden for HIV-positive people using age-specific cancer incidence data from the National Cancer Institute HIV/AIDS Cancer Match (HACM) Study, and projected HIV prevalence data from the Centers for Disease Control and Prevention.

Cancer incidence

From 2000 to 2012, there were 23,907 cancers reported in 463,300 HIV-infected adults in the HACM Study. Based on trends in this study, the researchers made projections for cancer incidence through 2030.

They projected that HIV-positive adults of all ages will see a significant decrease over time in the incidence of NHL, Kaposi sarcoma, cervical cancer, anal cancer among men who have sex with men (MSM), lung cancer, and Hodgkin lymphoma.

Patients age 65 and older will see a significant decrease in colon cancer incidence over time. However, there will be no significant change for patients younger than 65.

HIV-positive adults of all ages will see no significant change over time in the incidence of liver cancer, oral cavity cancer, anal cancer among non-MSMs, and breast cancer.

The incidence of prostate cancer will increase significantly among patients ages 35 to 44 and among patients ages 45 to 64.

Cancer burden

The researchers said the number of adults living with HIV in the US is projected to increase from 1.06 million in 2006 to 1.17 million in 2018, but it is expected to decline to 1.09 million in 2030.

The team noted that, in 2006, there were an estimated 8241 cancers in patients with HIV—3522 AIDS-defining cancers and 4719 malignancies not associated with AIDS.

In 2030, the total number of cancers in the HIV-positive population is projected to be 6692, with decreases in AIDS-defining cancers (n=716) and increases in other cancers (n=5976) from the 2006 data.

In 2010, the most common cancers among HIV-positive patients were estimated to be NHL (n=1488), Kaposi sarcoma (n=1133), and lung cancer (n=815).

But in 2030, the most common cancers are projected to be prostate (n=1587), lung (n=1027), and liver cancers (n=483).

“It is critical to understand both incidence rates and burden over time, as rates capture changes in cancer risk, and burden quantifies the actual number of cancer cases expected to occur,” said study investigator Meredith S. Shiels, PhD, of the National Cancer Institute in Bethesda, Maryland.

“For example, lung cancer rates are expected to decrease in the future, but the burden is expected to increase due to the growing number of older people living with HIV.”

The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended approval for the anti-PD-1 therapy pembrolizumab (Keytruda) as a treatment for patients with relapsed or refractory classical Hodgkin lymphoma (cHL).

The recommendation pertains specifically to adults with cHL who have failed autologous hematopoietic stem cell transplant (auto-HSCT) and treatment with brentuximab vedotin (BV) or adults with cHL who are transplant-ineligible and have failed treatment with BV.

The CHMP’s recommendation will be reviewed by the European Commission, which is expected to make a decision about the drug in the second quarter of 2017.

Pembrolizumab is already approved for use in the European Union as a treatment for melanoma and non-small-cell lung cancer.

The CHMP’s positive opinion of pembrolizumab for cHL was based on data from the KEYNOTE-087 and KEYNOTE-013 trials. Results from both trials were presented at ASH 2016 (abstract 1107 and abstract 1108).

KEYNOTE-087

KEYNOTE-087 is a phase 2 trial in which researchers evaluated pembrolizumab (a 200 mg fixed dose every 3 weeks) in patients with relapsed or refractory cHL across 3 cohorts:

• Cohort 1: Patients who progressed after auto-HSCT and subsequent treatment with BV
• Cohort 2: Patients who failed salvage chemotherapy, were ineligible for a transplant, and progressed after BV
• Cohort 3: Patients who progressed after auto-HSCT and did not receive BV after transplant.

Across all 210 enrolled patients, the overall response rate (ORR) was 69.0%, and the complete response (CR) rate was 22.4%.

In Cohort 1 (n=69), the ORR was 73.9%. The CR rate was 21.7%, the partial response (PR) rate was 52.2%, 15.9% of patients had stable disease (SD), and 7.2% progressed. In 82.2% of responders, the response lasted 6 months or more.

In Cohort 2 (n=81), the ORR was 64.2%. The CR rate was 24.7%, the PR rate was 39.5%, 12.3% of patients had SD, and 21.0% progressed. In 70.0% of responders, the response lasted 6 months or more.

In Cohort 3 (n=60), the ORR was 70.0%. Twenty percent of patients had a CR, 50.0% had a PR, 16.7% had SD, and 13.3% progressed. In 75.6% of responders, the response lasted 6 months or more.

Results also included an analysis of patients with primary refractory disease (n=73), which was defined as failure to achieve CR or PR with first-line treatment. In this patient population, the ORR was 79.5%.

An ORR of 67.8% was reported in patients who relapsed after 3 or more lines of prior therapy (99/146).

The most common treatment-related adverse events (AEs) were hypothyroidism (12.4%), pyrexia (10.5%), fatigue (9.0%), rash (7.6%), diarrhea (7.1%), headache (6.2%), nausea (5.7%), cough (5.7%), and neutropenia (5.2%).

The most common grade 3/4 treatment-related AEs were neutropenia (2.4%), diarrhea (1.0%), and dyspnea (1.0%). Immune-mediated AEs included pneumonitis (2.9%), hyperthyroidism (2.9%), colitis (1.0%), and myositis (1.0%).

There were 9 discontinuations because of treatment-related AEs and no treatment-related deaths.

KEYNOTE-013

KEYNOTE-013 is a phase 1b trial that has enrolled 31 patients with relapsed or refractory cHL who failed auto-HSCT and subsequent BV or who were transplant-ineligible.

Patients received pembrolizumab at 10 mg/kg every 2 weeks. The median duration of follow-up was 29 months.

The ORR was 58%. Nineteen percent of patients achieved a CR, 39% had a PR, and 23% had SD.

The median duration of response had not been reached at last follow-up (range, 0.0+ to 26.1+ months), and 70% of responding patients had a response lasting 12 months or more.

The median progression-free survival (PFS) was 11.4 months (range, 4.9-27.8 months). The six-month PFS rate was 66%, and the 12-month PFS rate was 48%.

The median overall survival was not reached. Six-month and 12-month overall survival rates were 100% and 87%, respectively.

The most common treatment-related AEs were diarrhea (19%), hypothyroidism (13%), pneumonitis (13%), nausea (13%), fatigue (10%), and dyspnea (10%).

The most common grade 3/4 treatment-related AEs were colitis (3%), axillary pain (3%), AST increase (3%), joint swelling (3%), nephrotic syndrome back pain (3%), and dyspnea (3%).

AEs leading to discontinuation were nephrotic syndrome (grade 3), interstitial lung disease (grade 2), and pneumonitis (grade 2). There were no treatment-related deaths.

The CHMP’s positive opinion of pembrolizumab for cHL was based on data from the KEYNOTE-087 and KEYNOTE-013 trials. Results from both trials were presented at ASH 2016 (abstract 1107 and abstract 1108).

KEYNOTE-087

KEYNOTE-087 is a phase 2 trial in which researchers evaluated pembrolizumab (a 200 mg fixed dose every 3 weeks) in patients with relapsed or refractory cHL across 3 cohorts:

• Cohort 1: Patients who progressed after auto-HSCT and subsequent treatment with BV
• Cohort 2: Patients who failed salvage chemotherapy, were ineligible for a transplant, and progressed after BV
• Cohort 3: Patients who progressed after auto-HSCT and did not receive BV after transplant.

Across all 210 enrolled patients, the overall response rate (ORR) was 69.0%, and the complete response (CR) rate was 22.4%.

In Cohort 1 (n=69), the ORR was 73.9%. The CR rate was 21.7%, the partial response (PR) rate was 52.2%, 15.9% of patients had stable disease (SD), and 7.2% progressed. In 82.2% of responders, the response lasted 6 months or more.

In Cohort 2 (n=81), the ORR was 64.2%. The CR rate was 24.7%, the PR rate was 39.5%, 12.3% of patients had SD, and 21.0% progressed. In 70.0% of responders, the response lasted 6 months or more.

In Cohort 3 (n=60), the ORR was 70.0%. Twenty percent of patients had a CR, 50.0% had a PR, 16.7% had SD, and 13.3% progressed. In 75.6% of responders, the response lasted 6 months or more.

Results also included an analysis of patients with primary refractory disease (n=73), which was defined as failure to achieve CR or PR with first-line treatment. In this patient population, the ORR was 79.5%.

An ORR of 67.8% was reported in patients who relapsed after 3 or more lines of prior therapy (99/146).

The most common treatment-related adverse events (AEs) were hypothyroidism (12.4%), pyrexia (10.5%), fatigue (9.0%), rash (7.6%), diarrhea (7.1%), headache (6.2%), nausea (5.7%), cough (5.7%), and neutropenia (5.2%).

The most common grade 3/4 treatment-related AEs were neutropenia (2.4%), diarrhea (1.0%), and dyspnea (1.0%). Immune-mediated AEs included pneumonitis (2.9%), hyperthyroidism (2.9%), colitis (1.0%), and myositis (1.0%).

There were 9 discontinuations because of treatment-related AEs and no treatment-related deaths.

KEYNOTE-013

KEYNOTE-013 is a phase 1b trial that has enrolled 31 patients with relapsed or refractory cHL who failed auto-HSCT and subsequent BV or who were transplant-ineligible.

Patients received pembrolizumab at 10 mg/kg every 2 weeks. The median duration of follow-up was 29 months.

The ORR was 58%. Nineteen percent of patients achieved a CR, 39% had a PR, and 23% had SD.

The median duration of response had not been reached at last follow-up (range, 0.0+ to 26.1+ months), and 70% of responding patients had a response lasting 12 months or more.

The median progression-free survival (PFS) was 11.4 months (range, 4.9-27.8 months). The six-month PFS rate was 66%, and the 12-month PFS rate was 48%.

The median overall survival was not reached. Six-month and 12-month overall survival rates were 100% and 87%, respectively.

The most common treatment-related AEs were diarrhea (19%), hypothyroidism (13%), pneumonitis (13%), nausea (13%), fatigue (10%), and dyspnea (10%).

The most common grade 3/4 treatment-related AEs were colitis (3%), axillary pain (3%), AST increase (3%), joint swelling (3%), nephrotic syndrome back pain (3%), and dyspnea (3%).

AEs leading to discontinuation were nephrotic syndrome (grade 3), interstitial lung disease (grade 2), and pneumonitis (grade 2). There were no treatment-related deaths.

General Medical Sciences

A new study supports the idea that most cancer-driving mutations are a result of DNA replication errors, not heredity or lifestyle/environmental factors.

For all 32 cancer types studied, researchers found that 66% of driver mutations resulted from DNA replication errors, 29% could be attributed to lifestyle or environmental factors, and the remaining 5% were inherited.

In hematologic malignancies, the percentage of mutations caused by DNA replication errors was even higher—70% in Hodgkin lymphoma, 85% in leukemias, 96% in non-Hodgkin lymphomas, and 99% in myeloma.

Cristian Tomasetti, PhD, of Johns Hopkins University School of Medicine in Baltimore, Maryland, and his colleagues reported these findings in Science.

“It is well-known that we must avoid environmental factors such as smoking to decrease our risk of getting cancer, but it is not as well-known that each time a normal cell divides and copies its DNA to produce 2 new cells, it makes multiple mistakes,” Dr Tomasetti said.

“These copying mistakes are a potent source of cancer mutations that, historically, have been scientifically undervalued, and this new work provides the first estimate of the fraction of mutations caused by these mistakes.”

In 2015, Dr Tomasetti and his colleagues reported that DNA replication errors could explain why certain cancers occur more often than others in the US.

The current study builds upon that research but includes additional cancers and encompasses an international population.

The researchers first studied the relationship between the number of normal stem cell divisions and the risk of 17 cancer types in 69 countries representing 4.8 billion people, or more than half of the world’s population.

The team said they observed a strong correlation between cancer incidence and normal stem cell divisions in all countries, regardless of their environment.

Next, the researchers set out to determine the percentage of driver mutations caused by DNA replication errors in 32 cancer types. The team developed a mathematical model using DNA sequencing data from The Cancer Genome Atlas and epidemiologic data from the Cancer Research UK database.

According to the researchers, it generally takes 2 or more critical mutations for cancer to occur. In an individual, these mutations can be due to random DNA replication errors, the environment, or inherited genes.

Knowing this, the researchers used their mathematical model to show, for example, that when critical mutations in leukemia are added together, 85.2% of them are due to random DNA replication errors, 14.3% to environmental factors, and 0.5% to heredity.

In Hodgkin lymphoma, 69.5% are due to DNA replication errors, 30% to environmental factors, and 0.5% to heredity. In non-Hodgkin lymphoma, 95.6% are due to random DNA replication errors, 3.9% to environmental factors, and 0.5% to heredity.

In myeloma, 99.3% are due to DNA replication errors, 0.2% to environmental factors, and 0.5% to heredity.

Dr Tomasetti said these random DNA replication errors will only get more important as aging populations continue to grow, prolonging the opportunity for cells to make more and more errors.

“We need to continue to encourage people to avoid environmental agents and lifestyles that increase their risk of developing cancer mutations,” said study author Bert Vogelstein, MD, of The Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins University.

“However, many people will still develop cancers due to these random DNA copying errors, and better methods to detect all cancers earlier, while they are still curable, are urgently needed.”
