SAN DIEGO — Fewer than half of the cancer drugs approved under the US Food and Drug Administration’s (FDA’s) accelerated approval pathway between 2013 and 2017 have been shown to improve overall survival or quality of life, despite being on the US market for more than 5 years, according to a new study. 

Under the program, drugs are approved for marketing if they show benefit in surrogate markers thought to indicate efficacy. Progression-free survival, tumor response, and duration of response are the most used surrogate markers for accelerated approvals of cancer drugs. These are based largely on imaging studies that show either a stop in growth in the case of progression-free survival or tumor shrinkage in the case of tumor response. 

Following accelerated approvals, companies are then supposed to show actual clinical benefit in confirmatory trials.

The problem with relying on surrogate markers for drug approvals is that they don’t always correlate with longer survival or improved quality of life, said Edward Cliff, MBBS, who presented the findings at the American Association for Cancer Research 2024 annual meeting (abstract 918). The study was also published in JAMA to coincide with the meeting presentation.

In some cancers, these markers work well, but in others they don’t, said Dr. Cliff, a hematology trainee at Brigham and Women’s Hospital, Boston, when the work was conducted, and now a hematology fellow at the Peter MacCallum Cancer Centre in Melbourne, Australia.

To determine whether cancer drugs granted accelerated approval ultimately show an overall survival or quality of life benefit, researchers reviewed 46 cancer drugs granted accelerated approvals between 2013 and 2017. Twenty (43%) were granted full approval after demonstrating survival or quality-of-life benefits. 

Nine, however, were converted to full approvals on the basis of surrogate markers. These include a full approval for pembrolizumab in previously treated recurrent or refractory head and neck squamous cell carcinoma and a full approval for nivolumab for refractory locally advanced or metastatic urothelial carcinoma, both based on tumor response rate and duration of response.

Of the remaining 17 drugs evaluated in the trial, 10 have been withdrawn and seven do not yet have confirmatory trial results. 

The reliance on surrogate markers means that these drugs are used for treatment, covered by insurance, and added to guidelines — all without solid evidence of real-world clinical benefit, said Dr. Cliff. 

However, the goal should not be to do away with the accelerated approval process, because it sometimes does deliver powerful agents to patients quickly. Instead, Dr. Cliff told this news organization, the system needs to be improved so that “we keep the speed while getting certainty around clinical benefits” with robust and timely confirmatory trials. 

In the meantime, “clinicians should communicate with patients about any residual uncertainty of clinical benefit when they offer novel therapies,” Dr. Cliff explained. “It’s important for them to have the information.”

There has been some progress on the issue. In December 2022, the US Congress passed the Food and Drug Administration Omnibus Reform Act. Among other things, the Act requires companies to have confirmation trials underway as a condition for accelerated approval, and to provide regular reports on their progress. The Act also expedites the withdrawal process for drugs that don’t show a benefit. 

The Act has been put to the test twice recently. In February, FDA used the expedited process to remove the multiple myeloma drug melphalan flufenamide from the market. Melphalan flufenamide hadn’t been sold in the US for quite some time, so the process wasn’t contentious. 

In March, Regeneron announced that accelerated approval for the follicular and diffuse B cell lymphoma drug odronextamab has been delayed pending enrollment in a confirmatory trial. 

“There have been some promising steps,” Dr. Cliff said, but much work needs to be done. 

Study moderator Shivaani Kummar, MD, agreed, noting that “the data is showing that the confirmatory trials aren’t happening at the pace which they should.” 

But the solution is not to curtail approvals; it’s to make sure that accelerated approval commitments are met, said Dr. Kummar.

Still, “as a practicing oncologist, I welcome the accelerated pathway,” Dr. Kummar, a medical oncologist/hematologist at Oregon Health & Science University, Portland, told this news organization. “I want the availability to my patients.” 

Having drugs approved on the basis of surrogate markers doesn’t necessarily mean patients are getting ineffective therapies, Dr. Kummar noted. For instance, if an agent just shrinks the tumor, it can sometimes still be “a huge clinical benefit because it can take the symptoms away.” 

As for prescribing drugs based on accelerated approvals, she said she tells her patients that trials have been promising, but we don’t know what the long-term effects are. She and her patient then make a decision together. 

The study was funded by Arnold Ventures. Dr. Kummar reported support from several companies, including Bayer, Gilead, and others. Dr. Cliff had no disclosures.

The US Food and Drug Administration (FDA) has approved idecabtagene vicleucel (ide-cel) (Abecma, Bristol-Myers Squibb/2seventy bio) for adults with relapsed or refractory multiple myeloma after two or more prior lines of therapy, including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 monoclonal antibody. 

The approval expands the chimeric antigen receptor (CAR) T-cell therapy’s indications to earlier lines of treatment after exposure to these other main therapy classes, Bristol Myers Squibb said in a press release. 

Approval was based on the KarMMa-3 trial, in which 254 patients were randomly assigned to ide-cel and 132 to investigators’ choice of standard regimens, consisting of combinations of daratumumab, dexamethasone, and other agents. 

After a median follow-up of 15.9 months, median progression-free survival was three times higher in the ide-cel arm: 13.3 months with the CAR T-cell therapy vs 4.4 months with standard treatment. Overall, 39% of patients on ide-cel had a complete response vs 5% on standard regimens. 

The approval includes a new recommended dose range of 300-510 x 106 CAR-positive T cells. 

Ide-cel carries a boxed warning for cytokine release syndrome, neurologic toxicities, hemophagocytic lymphohistiocytosis/macrophage activation syndrome, prolonged cytopenia, and secondary hematologic cancers. 

In trials, cytokine release syndrome occurred in 89% (310 of 349) of patients in the KarMMa-3 and KarMMa studies, which included grade 3 syndrome in 7% (23 of 349) and fatal cases in 0.9% (3 of 349) of patients.

A one-time treatment is over $500,000, according to drugs.com.

TOPLINE:

Being positive for Helicobacter pylori is associated with a higher risk for colorectal cancer (CRC) incidence and CRC mortality, new data show; however, a 2-week course of antibiotics to eliminate the bacterial infection can reduce the risk of developing and dying from CRC.

METHODOLOGY:

• H pylori is a known cause of peptic ulcers and stomach cancer and has been classified as a group I carcinogen by the World Health Organization›s International Agency for Research on Cancer.
• Studies showed that H pylori increases the risk for gastric cancer and may increase the risk for CRC, but evidence supporting the CRC connection remains inconsistent.
• To investigate a possible H pylori-CRC link, investigators reviewed CRC incidence and mortality in a nationwide cohort of 812,736 veterans tested for H pylori at Veterans Health Administration facilities; of the 205,178 (25.2%) who tested positive for H pylori, 134,417 (34%) were treated.
• Patients were followed from their first H pylori test, and researchers tracked subsequent CRC diagnoses as well as CRC-related and non-CRC–related deaths.

TAKEAWAY:

• H pylori infection was associated with an 18% higher risk for CRC (adjusted hazard ratio [aHR], 1.18) and a 12% higher risk for CRC mortality (aHR, 1.12).
• Untreated patients had a 23% higher risk for CRC (aHR, 1.23) and a 40% higher risk for CRC mortality (aHR, 1.40) than treated individuals.
• Over the 15-year follow-up, receiving treatment for H pylori infection vs no treatment was associated with a lower risk of developing and dying from CRC (absolute risk reduction, 0.23%-0.35%). For context, among individuals receiving a screening colonoscopy, the invasive test was associated with a 0.84%-1.22% absolute risk reduction in CRC incidence and a 0.15-0.30% absolute risk reduction in CRC mortality.
• Excluding patients diagnosed with CRC within a year of H pylori testing did not change the associations in the study.

IN PRACTICE:

“We would like to highlight the potentially exciting clinical implications of these findings,” the authors of an accompanying editorial wrote. “Although the mechanistic connection between H pylori and colorectal cancer is not fully resolved,” the finding that eliminating H pylori “could reduce both gastric and colorectal cancers is incredibly potent and should be considered in clinical care for individuals at high risk for GI [gastrointestinal] cancers.”

The work, led by Shailja C. Shah, MD, of the University of California San Diego, was published in the Journal of Clinical Oncology, alongside the accompanying editorial by Julia Butt, PhD, of the German Cancer Research Center, Heidelberg, Germany, and Meira Epplein, PhD, of Duke University in Durham, North Carolina.

LIMITATIONS:

The study was limited to US veterans, which means generalizability to other populations needed to be confirmed. There may have been differences in CRC risk factors between treated and untreated patients.

DISCLOSURES:

The work was funded by the Veterans Health Administration, the National Cancer Institute, and others. Investigators reported ties to numerous companies, including AstraZeneca, Novartis, Guardant Health, and Medscape Medical News, publisher of this article. The editorialists had no disclosures.

TOPLINE:

Using polygenic risk scores along with positive family histories and breast cancer-associated gene mutations improves risk stratification for breast cancer screening.

METHODOLOGY:

A polygenic risk score — a measure of an individual’s risk for a disease based on the estimated effects of many genetic variants — is not typically included alongside family histories and pathogenic variants of genes, such as BRCA1 and PALB2, when assessing a woman’s risk for breast cancer and the need for earlier or more frequent screening.

To assess the potential for a polygenic risk score to improve breast cancer risk stratification, investigators in Finland used a nationwide genetic database to calculate polygenic risk score scores for 117,252 women and then linked the scores to their breast cancer outcomes, using the country’s nationwide mammography screening program, which screens women, ages 50-69 years, every 2 years.

The researchers evaluated the use of polygenic risk scores both alone and in combination with family histories and pathogenic variants — specifically, CHEK2 and PALB2 variants common in Finland.

The researchers also looked at how well polygenic risk scores predicted a person’s risk for any breast cancer as well as invasive, in situ, and bilateral at three timepoints: before, during, and after screening age.

TAKEAWAY:

Compared with a lower polygenic risk score (below 90%), a high polygenic risk score — a score in the top 10% — was associated with more than a twofold higher risk for any breast cancer before, during, and after screening age (hazard ratio [HR], 2.50, 2.38, and 2.11, respectively). Pathogenic variants and family histories led to similar risk assessments (HR, 3.13, 2.30, and 1.95, respectively, for pathogenic variants; HR, 1.97, 1.96, and 1.68, respectively, for family history).

A high polygenic risk score had a positive predictive value of 39.5% for a breast cancer diagnosis after a positive screening mammography, about the same as positive family history (35.5%) and pathogenic variants (35.9%). Combining a high polygenic risk score with a positive family history increased the positive predictive value to 44.6% and with pathogenic variant carriers increased the positive predictive value to 50.6%.

A high polygenic risk score was also associated with a twofold higher risk for interval breast cancer — a cancer diagnosed between screenings — and a higher risk for bilateral breast cancer during screening ages (HR, 4.71), suggesting that women with high scores may benefit from a shorter time interval between screenings or earlier screening, the researchers said.

Women with scores in the bottom 10% had a very low risk for both interval and screen-detected cancers. Those with negative family histories and no pathogenic variants did not reach the 2% cumulative incidence threshold for breast cancer screening until age 62 years, “suggesting opportunities for less frequent screens,” the researchers noted.

IN PRACTICE:

This study demonstrates the effectiveness of using a breast cancer polygenic risk score for risk stratification, “with optimal stratification reached through combining” this information with family history and pathogenic variants, the researchers concluded.

SOURCE:

The study, led by Nina Mars, MD, PhD, of the University of Helsinki, Helsinki, Finland, was published in the Journal of Clinical Oncology.

LIMITATIONS:

The work was limited largely to people with Finnish genetic ancestry. The benefits of including polygenic risk scores in screening programs need to be confirmed in clinical trials in areas with broader genetic ancestry; several trials are underway in the United States and elsewhere.

DISCLOSURES:

The study was funded by the European Union’s Horizon 2020 research and innovation program, the Cancer Foundation Finland, and others. The investigators didn’t have any relevant disclosures.

A polygenic risk score — a measure of an individual’s risk for a disease based on the estimated effects of many genetic variants — is not typically included alongside family histories and pathogenic variants of genes, such as BRCA1 and PALB2, when assessing a woman’s risk for breast cancer and the need for earlier or more frequent screening.

To assess the potential for a polygenic risk score to improve breast cancer risk stratification, investigators in Finland used a nationwide genetic database to calculate polygenic risk score scores for 117,252 women and then linked the scores to their breast cancer outcomes, using the country’s nationwide mammography screening program, which screens women, ages 50-69 years, every 2 years.

The researchers evaluated the use of polygenic risk scores both alone and in combination with family histories and pathogenic variants — specifically, CHEK2 and PALB2 variants common in Finland.

The researchers also looked at how well polygenic risk scores predicted a person’s risk for any breast cancer as well as invasive, in situ, and bilateral at three timepoints: before, during, and after screening age.

TAKEAWAY:

Compared with a lower polygenic risk score (below 90%), a high polygenic risk score — a score in the top 10% — was associated with more than a twofold higher risk for any breast cancer before, during, and after screening age (hazard ratio [HR], 2.50, 2.38, and 2.11, respectively). Pathogenic variants and family histories led to similar risk assessments (HR, 3.13, 2.30, and 1.95, respectively, for pathogenic variants; HR, 1.97, 1.96, and 1.68, respectively, for family history).

A high polygenic risk score had a positive predictive value of 39.5% for a breast cancer diagnosis after a positive screening mammography, about the same as positive family history (35.5%) and pathogenic variants (35.9%). Combining a high polygenic risk score with a positive family history increased the positive predictive value to 44.6% and with pathogenic variant carriers increased the positive predictive value to 50.6%.

A high polygenic risk score was also associated with a twofold higher risk for interval breast cancer — a cancer diagnosed between screenings — and a higher risk for bilateral breast cancer during screening ages (HR, 4.71), suggesting that women with high scores may benefit from a shorter time interval between screenings or earlier screening, the researchers said.

Women with scores in the bottom 10% had a very low risk for both interval and screen-detected cancers. Those with negative family histories and no pathogenic variants did not reach the 2% cumulative incidence threshold for breast cancer screening until age 62 years, “suggesting opportunities for less frequent screens,” the researchers noted.

IN PRACTICE:

This study demonstrates the effectiveness of using a breast cancer polygenic risk score for risk stratification, “with optimal stratification reached through combining” this information with family history and pathogenic variants, the researchers concluded.

SOURCE:

The study, led by Nina Mars, MD, PhD, of the University of Helsinki, Helsinki, Finland, was published in the Journal of Clinical Oncology.

LIMITATIONS:

The work was limited largely to people with Finnish genetic ancestry. The benefits of including polygenic risk scores in screening programs need to be confirmed in clinical trials in areas with broader genetic ancestry; several trials are underway in the United States and elsewhere.

DISCLOSURES:

The study was funded by the European Union’s Horizon 2020 research and innovation program, the Cancer Foundation Finland, and others. The investigators didn’t have any relevant disclosures.

The US Food and Drug Administration has approved danicopan (Voydeya, AstraZeneca) as an add-on therapy to treat extravascular hemolysis in adults receiving ravulizumab or eculizumab for paroxysmal nocturnal hemoglobinuria (PNH), according to a press release from AstraZeneca.

PNH is a rare blood disorder affecting 1-10 individuals per million. The condition, which eliminates red blood cells and leads to blood clots and impaired bone marrow function, can cause life-threatening anemia, thrombosis, and bone marrow dysfunction. About half of people with the condition die from thrombotic complications.

Ravulizumab and eculizumab, also both made by AstraZeneca, inhibit the destruction of red blood cells. However, 10%-20% of patients treated with the antibody infusions experience significant extravascular hemolysis, in which these surviving red blood cells are eliminated by the spleen and liver. Extravascular hemolysis can lead to ongoing anemia, which can lead patients to require blood transfusions.

Danicopan, an investigational, first-in-class, oral complement factor D inhibitor, is designed to control intravascular hemolysis and prevent extravascular hemolysis.

Approval of the oral medication was based on the phase 3 ALPHA trial in 63 patients with PNH who received ravulizumab or eculizumab and experienced significant extravascular hemolysis. These patients were randomized 2:1 to either danicopan or placebo.

Danicopan add-on significantly improved hemoglobin concentrations at 12 weeks (least squares mean improvement from baseline: 2.94 g/dL with danicopan vs 0.50 g/dL with placebo) and made transfusions less likely.

Headache, nausea, arthralgia, and diarrhea were the most common treatment-emergent side effects. Serious adverse events in the danicopan group included cholecystitis and COVID-19 in one patient each.

Danicopan carries a boxed warning of serious infections and is available only through a Risk Evaluation and Mitigation Strategy program.

Adding low-dose radiation to the current standard first-line treatment, durvalumab plus etoposide-platinum chemotherapy, appears to improve survival outcomes in patients with extensive-stage small cell lung cancer (SCLC), suggested new findings from a small, single-arm study.

The analysis, presented at the 2024 European Lung Cancer Congress, revealed that low-dose radiation improved patients’ median progression-free and overall survival compared with standard first-line treatment, reported in a 2019 trial, lead author Yan Zhang, MD, reported.

The standard first-line treatment results came from the 2019 CASPIAN trial, which found that patients receiving the first-line regimen had a median progression-free survival of 5 months and a median overall survival of 13 months, with 54% of patient alive at 1 year.

The latest data, which included a small cohort of 30 patients, revealed that adding low-dose radiation to the standard first-line therapy led to a higher median progression-free survival of 8.3 months and extended median overall survival beyond the study follow-up period of 17.3 months. Overall, 66% of patients were alive at 1 year.

These are “promising” improvements over CASPIAN, Dr. Zhang, a lung cancer medical oncologist at Sichuan University, Chengdu, China, said at the Congress, which was organized by the European Society for Medical Oncology.

Study discussant Gerry Hanna, PhD, MBBS, a radiation oncologist at Belfast City Hospital, Belfast, Northern Ireland, agreed. Although there were just 30 patients, “you cannot deny these are [strong] results in terms of extensive-stage small cell cancer,” Dr. Hanna said.

Although standard first-line treatment of extensive-stage SCLC is durvalumab plus etoposide-platinum chemotherapy, the benefits aren’t durable for many patients.

This problem led Dr. Zhang and his colleagues to look for ways to improve outcomes. Because the CASPIAN trial did not include radiation to the primary tumor, it seemed a logical strategy to explore.

In the current single-arm study, Dr. Zhang and his team added 15 Gy radiation in five fractions to the primary lung tumors of 30 patients during the first cycle of durvalumab plus etoposide-platinum.

Subjects received 1500 mg of durvalumab plus etoposide-platinum every 3 weeks for four cycles. Low-dose radiation to the primary tumor was delivered over 5 days at the start of treatment. Patients then continued with durvalumab maintenance every 4 weeks until progression or intolerable toxicity.

Six patients (20%) had liver metastases at the baseline, and three (10%) had brain metastases. Over half had prophylactic cranial radiation. Performance scores were 0-1, and all but one of the participants were men.

Six- and 12-month progression-free survival rates were 57% and 40%, respectively. Overall survival was 90% at 6 months and 66% at 12 months. Median overall survival was 13 months in the CASPIAN trial but not reached in Dr. Zhang’s trial after a median follow-up of 17.3 months, with the earliest deaths occurring at 10.8 months.

Grade 3 treatment-related adverse events occurred in 80% of patients, most frequently hematologic toxicities. Five patients (16.7%) had severe adverse reactions to radiation. Although the overall dose of radiation was low, at 3 Gy each, the fractions were on the large side.

Hanna wanted more information on the radiotoxicity issue, but even so, he said that adding low-dose radiation to our durvalumab-chemotherapy doublet warrants further investigation.

Both Dr. Hanna and Dr. Zhang thought that instead of killing cancer cells directly, the greatest benefit of upfront radiation, and the peritumoral inflammation it causes, is to augment durvalumab’s effect.

Overall, Dr. Hanna stressed that we haven’t had results like these before in a SCLC study, particularly for novel agents, let alone radiation.

The study was funded by AstraZeneca, maker of durvalumab. Dr. Zhang and Dr. Hanna didn’t have any relevant disclosures.

The US Food and Drug Administration has granted ponatinib (Iclusig, Takeda) accelerated approval for use with chemotherapy in adults with newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL).

The approval makes the third-generation tyrosine kinase inhibitor (TKI) the first targeted treatment approved for upfront use in adults with Ph+ ALL, Takeda said in a press release.

Ponatinib was previously approved as monotherapy for Ph+ ALL when no other kinase inhibitors are indicated or for T315I-positive Ph+ ALL, as well as for chronic myeloid leukemia.

Approval for the new indication was based on the PhALLCON trial. In the trial, 245 patients were randomized 2:1 to either ponatinib 30 mg once daily or the first-generation TKI imatinib (Gleevec, Novartis) 600 mg once daily on a chemotherapy background consisting of three cycles of vincristine/dexamethasone induction, six cycles methotrexate/cytarabine consolidation, and 11 cycles of vincristine/prednisone maintenance.

At the end of induction, 12% of patients in the imatinib arm vs 30% in the ponatinib group were in complete remission with no minimal residual disease. Event-free survival data are not yet mature.

At the 2023 American Society of Clinical Oncology annual meeting, an investigator on the trial said that ponatinib plus low-intensity chemotherapy has the potential to become the new standard of care for upfront Ph+ All. However, continued approval for the new indication may depend on trials confirming clinical benefit, Takeda said.

Ponatinib carries a boxed warning of arterial occlusive events, venous thromboembolic events, heart failure, and hepatotoxicity.

The most common adverse reactions reported in the PhALLCON trial were hepatic dysfunction, arthralgia, rash, headache, pyrexia, abdominal pain, constipation, fatigue, nausea, oral mucositis, hypertension, pancreatitis/elevated lipase, peripheral neuropathy, hemorrhage, febrile neutropenia, fluid retention and edema, vomiting, paresthesia, and cardiac arrhythmias.

The recommended ponatinib dose is 30 mg orally once daily until the end of induction, dropping down to 15 mg once daily in patients who go into remission with no minimal residual disease after induction, for up to 20 cycles or until loss of response or unacceptable toxicity.

Thirty tablets of 30 mg or 15 mg cost $21,944.54, according to Drugs.com.

The US Food and Drug Administration has granted accelerated approval to the Bruton’s kinase inhibitor zanubrutinib (Brukinsa, BeiGene USA) with obinutuzumab (Gazyva, Roche) for relapsed or refractory follicular lymphoma after two or more lines of systemic therapy.

Approval was based on the ROSEWOOD trial, which included 217 adults with relapsed or refractory follicular lymphoma randomized 2:1 to obinutuzumab plus zanubrutinib 160 mg orally twice daily until disease progression or unacceptable toxicity or to obinutuzumab alone. Participants had a median of three prior lines of treatment and as many as 11. 

The overall response rate was 69% with zanubrutinib add-on vs 46% with stand-alone obinutuzumab (P = .0012). After a median follow-up of 19 months, the median duration of response was 14 months with obinutuzumab alone but not reached in the combination arm and estimated to be 69% at 18 months.

Across clinical trials, the most common adverse events with zanubrutinib were decreased neutrophil counts (51%), decreased platelet counts (41%), upper respiratory tract infection (38%), hemorrhage (32%), and musculoskeletal pain (31%). Serious adverse reactions occurred in 35% of patients.

The recommended zanubrutinib dose is 160 mg taken orally twice daily or 320 mg taken orally once daily until disease progression or unacceptable toxicity.

Previously approved indications for the kinase inhibitor include mantle cell lymphoma, Waldenström’s macroglobulinemia, chronic lymphocytic leukemia, and small lymphocytic lymphoma.

The US Food and Drug Administration has granted accelerated approval to the Bruton’s kinase inhibitor zanubrutinib (Brukinsa, BeiGene USA) with obinutuzumab (Gazyva, Roche) for relapsed or refractory follicular lymphoma after two or more lines of systemic therapy.

Approval was based on the ROSEWOOD trial, which included 217 adults with relapsed or refractory follicular lymphoma randomized 2:1 to obinutuzumab plus zanubrutinib 160 mg orally twice daily until disease progression or unacceptable toxicity or to obinutuzumab alone. Participants had a median of three prior lines of treatment and as many as 11. 

The overall response rate was 69% with zanubrutinib add-on vs 46% with stand-alone obinutuzumab (P = .0012). After a median follow-up of 19 months, the median duration of response was 14 months with obinutuzumab alone but not reached in the combination arm and estimated to be 69% at 18 months.

The US Food and Drug Administration has approved nivolumab (Opdivo, Bristol-Myers Squibb) in combination with cisplatin and gemcitabine for first-line treatment of adults with unresectable or metastatic urothelial carcinoma.

Approval was based on the CHECKMATE-901 trial in 608 patients randomized equally to either cisplatin and gemcitabine for ≤ six cycles or nivolumab plus cisplatin and gemcitabine for ≤ six cycles, followed by nivolumab alone for ≤ 2 years. 

Median overall survival was 21.7 months with nivolumab add-on vs 18.9 months with cisplatin/gemcitabine alone (hazard ratio [HR], 0.78; P = .0171). The nivolumab group had a slightly higher median progression-free survival of 7.9 months vs 7.6 months in the cisplatin and gemcitabine group (HR, 0.72; P = .0012).

The most common adverse events, occurring in ≥ 15% of nivolumab patients, were nausea, fatigue, musculoskeletal pain, constipation, decreased appetite, rash, vomiting, peripheral neuropathy, urinary tract infection, diarrhea, edema, hypothyroidism, and pruritus.

Among numerous other oncology indications, nivolumab was previously approved for adjuvant treatment following urothelial carcinoma resection and for locally advanced or metastatic urothelial carcinoma that progresses during or following platinum-containing chemotherapy.

The US Food and Drug Administration has expanded the indication of inotuzumab ozogamicin (Besponsa, Pfizer) to include children aged ≥ 1 year with relapsed or refractory CD22-positive B-cell precursor acute lymphoblastic leukemia (ALL).

The CD22-directed antibody and cytotoxic drug conjugate was previously approved only for adults with the condition. 

Pediatric approval was based on a single-arm study of 53 children, of whom 12 were treated with an initial dose of 1.4 mg/m^{2 per} cycle and the rest with an initial dose of 1.8 mg/m² per cycle for a median of two cycles and a range of one to four cycles. 

Premedications included methylprednisolone plus an antipyretic and antihistamine.

Overall, 22 children (42%) had a complete remission, defined as < 5% blasts in the bone marrow, no leukemia blasts in peripheral blood, full recovery of peripheral blood counts, and resolution of extramedullary disease. The median duration of complete remission was 8.2 months. 

All but one child who went into complete remission (95.5%) had no minimal residual disease (MRD) by flow cytometry, and 19 (86.4%) were MRD negative by real-time quantitative polymerase chain reaction.

Adverse events in ≥ 20% of participants included thrombocytopenia, pyrexia, anemia, vomiting, infection, hemorrhage, neutropenia, nausea, leukopenia, febrile neutropenia, increased transaminases, abdominal pain, and headache.

The antibody-drug conjugate carries a black box warning of hepatotoxicity, including hepatic veno-occlusive and post-hematopoietic stem cell transplant mortality.

The initial recommended dose is 1.8 mg/m² per cycle, divided into 0.8 mg/m² on day 1, followed by 0.5 mg/m² on day 9 and 0.5 mg/m² on day 15. The initial 3-week cycle can be extended to 4 weeks for patients who have a complete remission or a complete remission with incomplete hematologic recovery and/or to recover from toxicities. 

According to drugs.com, 0.9 mg costs $23,423.47.
