Vyxeos, a liposome-encapsulated combination of daunorubicin and cytarabine, has been approved for the treatment of adults with newly-diagnosed therapy-related AML (t-AML) and AML with myelodysplasia-related changes (AML-MRC), the Food and Drug Administration announced on Aug. 3.

Vyxeos is the first FDA-approved treatment specifically for patients with t-AML or AML-MRC, the FDA said in its press release announcing the approval.



“Vyxeos is the first chemotherapy to demonstrate an overall survival advantage over the standard of care in a phase 3 randomized study of older adults with newly-diagnosed therapy-related AML or AML with myelodysplasia-related changes,” Jeffrey E. Lancet, MD, an investigator in the clinical trials of Vyxeos and chair of the department of malignant hematology at the H. Lee Moffitt Cancer Center in Tampa, Fla., said in a press release.

Vyxeos was associated with a median overall survival of 9.6 months and a standard combination of cytarabine and daunorubicin (7+3) was associated with a median survival of 5.9 months in a randomized, multicenter, open-label trial of 309 patients aged 60-75 years with newly-diagnosed t-AML or AML-MRC. Data from the study, which is NCT01696084, was the basis for the drug’s approval.

Vyxeos is a fixed-dose combination with each Vyxeos vial containing 44 mg daunorubicin and 100 mg cytarabine encapsulated together in liposomes. As dosing is based on the daunorubicin component, the corresponding cytarabine dose does not need to be calculated. Daunorubicin dosing is calculated on the basis of body surface area (mg/m2).

For the first induction cycle, the recommended Vyxeos dose is daunorubicin 44 mg/m2 (cytarabine 100 mg/m2) infused intravenously over 90 minutes on days 1, 3, and 5. If a second induction cycle is needed, the same dose is administered on days 1 and 3. The recommended dose of Vyxeos for each cycle of consolidation therapy is daunorubicin 29 mg/m2 (cytarabine 65 mg/m2) liposome via intravenous infusion over 90 minutes on days 1 and 3.

Adverse reactions occurring in at least 25% of treated patients in the clinical trial included hemorrhage, febrile neutropenia, rash, edema, nausea, mucositis, diarrhea, constipation, musculoskeletal pain, fatigue, abdominal pain, dyspnea, headache, cough, decreased appetite, arrhythmia, pneumonia, bacteremia, chills, sleep disorders, and vomiting.

The prescribing information includes a boxed warning not to substitute Vyxeos with other daunorubicin- or cytarabine-containing products. Full prescribing information is available at: www.accessdata.fda.gov/drugsatfda_docs/label/2017/209401s000lbl.pdf

The maker of Vyxeos is Jazz Pharmaceuticals.

LIFSCREEN data support broader cancer screening in Li-Fraumeni syndrome

Broader cancer screening of individuals with Li-Fraumeni syndrome (LFS), with or without whole-body magnetic resonance imaging, has a good diagnostic yield and identifies a wide range of cancers, according to a preliminary analysis of the ongoing LIFSCREEN phase 3, randomized, controlled trial.

Investigators led by Olivier Caron, MD, chair of the oncogenetics committee, department of medical oncology, at the Gustave Roussy University Hospital in Villejuif, France, enrolled in the trial 107 individuals from 75 families carrying a TP53 mutation, a genetic aberration commonly present in LFS that confers heightened risk of a variety of malignancies.

Participants had a median age at baseline of 32.9 years, with a range from 5 to 67 years. Fully 98% had a family history of cancer, and 48% had a personal history of cancer.

The participants were assigned to 5 years of standard screening – annual clinical examination, abdomen and pelvis ultrasound, brain MRI, complete blood cell count, and, for women older than 20 years, breast ultrasound and MRI – or intensive screening, entailing the addition of diffusion whole-body MRI.

At the time of the preliminary analysis, 15 patients had undergone only one round of screening; 35, two rounds; 19, three rounds; 24, four rounds; and 7, five rounds, Dr. Caron and associates reported in a research letter (JAMA Oncol. 2017; Aug 3 doi: 10.1001/jamaoncol.2017.1358).

Collectively, this amounted to 226.4 person-years of follow-up.

Screening with either trial strategy (with or without whole-body MRI) led to diagnosis of 23 new primary cancers in 20 patients. Nearly half of the total (12 cancers) were detected at the first round. Patients had a median age of 39.8 at the new cancer diagnosis, with a range from 6 to 70 years.

Of the new cancers, 10 belonged to the core LFS spectrum of breast cancer, sarcoma, and brain tumors. However, the other 13 were outside that spectrum, for example, lung adenocarcinomas, all seen in never or light smokers, and leukemias. Screening also detected three relapses of previous cancers.

Analyses further showed that prior cancer diagnosis was not a reliable marker for risk of new primaries. Although 12 of the patients with a screening-detected new primary had a personal cancer history, 8 did not (P = .22).

“The proportion and diversity of off–core LFS spectrum cancers detected in TP53 mutation carriers as reported by others give growing evidence of a broader LFS spectrum, in agreement with the permissive role of TP53 mutations,” write Dr. Caron and colleagues, who report having no relevant disclosures. “Our observations seem to support recent moves toward broader cancer screening in TP53 mutation carriers.”

The investigators continue to collect data in LIFSCREEN and plan to undertake main analysis later this year. “Our final analysis will help to determine the benefits and drawbacks (mostly related to false-positive test results) of whole-body MRI in TP53 mutation carrier surveillance,” they conclude. “Studies focused on TP53 mutation penetrance, using methods limiting selection bias, are required to refine cancer risks to improve TP53 mutation carrier management.”

FDA approves enasidenib to treat relapsed/refractory AML

Photo from Business Wire
Enasidenib (IDHIFA®)

The US Food and Drug Administration (FDA) has approved marketing of the oral IDH2 inhibitor enasidenib (IDHIFA®).

The drug is now approved to treat adults with relapsed or refractory acute myeloid leukemia (AML) and an IDH2 mutation, as detected by an FDA-approved test.

Enasidenib is available in 50 mg and 100 mg tablets. The recommended dose is 100 mg once daily until disease progression or unacceptable toxicity.

The prescribing information for enasidenib includes a boxed warning that the drug may cause differentiation syndrome, and this adverse event (AE) can be fatal if not treated.

Signs and symptoms of differentiation syndrome may include fever, dyspnea, acute respiratory distress, radiographic pulmonary infiltrates, pleural or pericardial effusions, rapid weight gain, peripheral edema, and hepatic, renal, or multi-organ dysfunction. At first suspicion of symptoms, doctors should treat patients with corticosteroids and monitor patients closely until symptoms resolve.

Companion diagnostic

Enasidenib was approved concurrently with the Abbott RealTime™ IDH2 companion diagnostic test, which was approved as an aid in identifying AML patients for treatment with enasidenib.

The FDA granted approval of enasidenib to Celgene Corporation and approval of the RealTime IDH2 Assay to Abbott Laboratories.

Enasidenib is licensed from Agios Pharmaceuticals.

Trial results

The FDA’s approval of enasidenib and the companion diagnostic test was based on data from a phase 1/2 trial (Study AG221-C-001, NCT01915498).

Data from this trial were recently presented at the ASCO 2017 Annual Meeting. However, the definitive data are included in the prescribing information for enasidenib.

The prescribing information includes efficacy data for 199 adults with relapsed/refractory AML and an IDH2 mutation. IDH2 mutations were identified or confirmed by the Abbott RealTime™ IDH2 test.

The 199 patients received enasidenib at a starting dose of 100 mg daily until disease progression or unacceptable toxicity. Dose reductions were allowed to manage side effects.

The patients’ median age was 68 (range, 19 to 100). They received a median of 2 prior anticancer regimens (range, 1 to 6). More than half (52%) were refractory to previous therapy.

The rate of complete response (CR) or CR with partial hematologic improvement (CRh) was 23% (n=46). The median duration of CR/CRh was 8.2 months (range, 4.3 to 19.4).

For patients who achieved a CR/CRh, the median time to first response was 1.9 months (range, 0.5 to 7.5), and the median time to best response of CR/CRh was 3.7 months (range, 0.6 to 11.2).

Among the 157 patients who were dependent on red blood cell (RBC) and/or platelet transfusions at baseline, 53 (34%) became independent of RBC and platelet transfusions during any 56-day period post-baseline.

Of the 42 patients who were independent of both RBC and platelet transfusions at baseline, 32 (76%) remained transfusion independent during any 56-day post-baseline period.

Researchers evaluated the safety of enasidenib in 214 patients. The median duration of exposure to enasidenib was 4.3 months (range, 0.3 to 23.6).

The most common AEs of any grade (≥20%) were nausea, vomiting, diarrhea, elevated bilirubin, and decreased appetite.

Serious AEs were reported in 77.1% of patients. The most frequent serious AEs (≥2%) were leukocytosis, diarrhea, nausea, vomiting, decreased appetite, tumor lysis syndrome, and differentiation syndrome.

The 30-day and 60-day mortality rates were 4.2% (9/214) and 11.7% (25/214), respectively.

Delirium linked to early death in advanced cancer patients

A diagnosis of delirium during a visit to the emergency department (ED) is a poor prognostic factor for patients with advanced cancer, according to research published in The Oncologist.

The study showed that patients with advanced cancer who were diagnosed with delirium during an ED visit were more likely to be admitted to the hospital or intensive care unit (ICU) and more likely to die earlier than patients without delirium.

This shows the importance of accurately diagnosing delirium in advanced cancer patients, said Ahmed Elsayem, MD, of the University of Texas MD Anderson Cancer Center in Houston.

Previous studies have shown that delirium is associated with poor survival in advanced cancer patients being treated in ICUs or receiving palliative care in hospices, but no one had investigated whether the same was true for patients visiting EDs.

“To the best our knowledge, this is the first study to show the poor survival of advanced cancer patients in the emergency department setting,” Dr Elsayem said.

He and his colleagues previously conducted a study in which they assessed the frequency of delirium in advanced cancer patients visiting the ED at MD Anderson. The researchers tested for delirium using 2 questionnaires—the Confusion Assessment Method (CAM) and Memorial Delirium Assessment Scale (MDAS).

Questioning 243 patients in total, the team found that 44 patients, or 18%, were suffering with delirium according to at least 1 of the questionnaires.

In the current study, Dr Elsayem and his colleagues determined how many of these cancer patients, with and without delirium, were subsequently admitted to hospital and ICUs, as well as how long the patients lived after their visit to the ED.

Results

The rate of hospitalization was 82% among patients with delirium according to CAM and/or MDAS, 77% among patients with delirium according to MDAS only, and 49% among patients without delirium (P=0.0013). Rates of ICU admission were 18%, 14%, and 2%, respectively (P=0.0004).

The median overall survival was 1.23 months for patients with delirium according to CAM and/or MDAS, 4.70 months for patients with delirium according to MDAS only, and 10.45 months for patients without delirium. The difference between the patients with and without delirium was significant (P<0.0001).

Given the influence delirium appears to have on survival, Dr Elsayem said prompt diagnosis and management in hospital EDs is essential.

He noted that, in many cases, delirium in advanced cancer patients can be resolved by simply stopping or modifying their medication and treating any associated infections.

“Treating the triggers if known—such as stopping medications—is the main treatment for an episode of delirium,” Dr Elsayem said.

He also suggested that further research needs to be done on this topic, including conducting similar studies on delirium in advanced cancer patients in other EDs and with larger groups of patients.

A diagnosis of delirium during a visit to the emergency department (ED) is a poor prognostic factor for patients with advanced cancer, according to research published in The Oncologist.

The study showed that patients with advanced cancer who were diagnosed with delirium during an ED visit were more likely to be admitted to the hospital or intensive care unit (ICU) and more likely to die earlier than patients without delirium.

This shows the importance of accurately diagnosing delirium in advanced cancer patients, said Ahmed Elsayem, MD, of the University of Texas MD Anderson Cancer Center in Houston.

Previous studies have shown that delirium is associated with poor survival in advanced cancer patients being treated in ICUs or receiving palliative care in hospices, but no one had investigated whether the same was true for patients visiting EDs.

“To the best our knowledge, this is the first study to show the poor survival of advanced cancer patients in the emergency department setting,” Dr Elsayem said.

He and his colleagues previously conducted a study in which they assessed the frequency of delirium in advanced cancer patients visiting the ED at MD Anderson. The researchers tested for delirium using 2 questionnaires—the Confusion Assessment Method (CAM) and Memorial Delirium Assessment Scale (MDAS).

Questioning 243 patients in total, the team found that 44 patients, or 18%, were suffering with delirium according to at least 1 of the questionnaires.

Enasidenib gets FDA approval for AML with IDH2 mutations

Article Type
Changed
Fri, 01/04/2019 - 10:07

 

Enasidenib has been approved for the treatment of adult patients with relapsed or refractory acute myeloid leukemia (AML) and specific mutations in the IDH2 gene, the U.S. Food and Drug Administration announced on Aug. 1.

The drug is approved for use with a companion diagnostic, the RealTime IDH2 Assay, which is used to detect IDH2 gene mutations. The FDA granted the approval of enasidenib (Idhifa) to the Celgene Corp. and the approval of the companion RealTime IDH2 Assay to Abbott Laboratories. Idhifa had Priority Review and Orphan Drug designations.

“Idhifa is a targeted therapy that fills an unmet need for patients with relapsed or refractory AML who have an IDH2 mutation,” said Richard Pazdur, MD, director of the FDA’s Oncology Center of Excellence and acting director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research. “The use of Idhifa was associated with a complete remission in some patients and a reduction in the need for both red cell and platelet transfusions.”

In data reported at the annual congress of the European Hematology Association, the overall response rate to enasidenib among 214 patients with IDH2 gene mutations treated at the 100-mg/day dose was 37%. This included 20.1% with a complete remission, 7.9% with complete remission with incomplete recovery of platelets or incomplete hematologic recovery, 3.7% with partial responses, and 5.1% with a morphologic leukemia-free state, according to Eytan M. Stein, MD, an internist and hematologic oncologist at the Memorial Sloan Kettering Cancer Center in New York.

According to an FDA press release, 34% of 157 patients who required transfusions of blood or platelets at the start of the study no longer required transfusions after treatment.

For 8%-19% of AML patients, the mutated IDH2 enzyme blocks normal blood cell development and results in an overabundance of immature blood cells, Celgene said in an announcement.

Common side effects of enasidenib, an isocitrate dehydrogenase-2 inhibitor, include nausea, vomiting, diarrhea, hyperbilirubinemia, and decreased appetite.

Fatal differentiation syndrome can occur and is treated with corticosteroids. The prescribing information for Idhifa includes a boxed warning regarding that risk. Symptoms of differentiation syndrome may include fever, dyspnea, acute respiratory distress, radiographic pulmonary infiltrates, pleural or pericardial effusions, rapid weight gain, peripheral edema, or hepatic, renal or multi-organ dysfunction, according to a press release issued by the FDA.

Examining Methods for Systematically Identifying Cytogenetic Testing Among Chronic Lymphoblastic Leukemia Patients

Article Type
Changed
Fri, 09/08/2017 - 12:05
Abstract 10: 2017 AVAHO Meeting

Purpose: To evaluate data extraction methods for identifying cytogenetic and fluorescence in situ hybridization (FISH) testing among chronic lymphoblastic leukemia (CLL) patients in the Veterans Health Administration (VHA).

Background: Cytogenetic/FISH testing are increasingly important for assessing risk and guiding therapy in patients with CLL. Administrative health data are frequently used to study testing practices; however, they are limited in their sensitivity and reliability. Increasing adoption of electronic health records (EHR) presents an opportunity to describe clinical practices in large patient populations. We compare three different EHR extraction methods to identify cytogenetic/ FISH testing in a cohort of CLL patients treated within the VHA.

Methods: CLL patients were identified using the VA Clinical Cancer Registry. Testing information was extracted from time of diagnosis to time of first treatment using three methods: (1) Current Procedural Terminology (CPT) codes; (2) Text mining of healthcare provider orders (HPO); (3) Clinical Lab Information Retrieval (CLIR), a previously validated conceptual framework that incorporates LOINC codes and test names that are then validated using test result information.

Results: 1,363 CLL patients were diagnosed and followed until their first line of therapy at VHA between 2008 and 2016: 635 (47%) had evidence of testing by text mining of HPO, 554 (41%) by CPT, and 399 (29%) by CLIR. Comparing CPT vs combined CLIR+HPO, CPT extraction had
a sensitivity of 52.8%, a precision of 73.1% and an F-measure of 0.613. Cytogenetic/FISH testing increased by nearly two-fold from 2008 to 2016, regardless of extraction method: HPO text mining (25% to 51%), CPT (20% to 54%), or CLIR (19% to 32%).

Conclusions: Advanced EHR extraction methods offer a more granular description of testing practices than administrative data alone as they examine multiple components of the EHR including the ordering, processing, and results of testing occurrences. Results suggest that there has been a slow increase in the number of CLL patients undergoing cytogenetic/FISH testing during the past decade, which is comparable to similar reports of testing practices outside the VHA, although approximately half of all CLL patients are not undergoing testing despite established clinical guideline recommendations.

Understanding childhood cancer in sub-Saharan Africa

Researchers say they have published the most extensive data ever collected on childhood cancer in sub-Saharan Africa.

On the African continent, only South Africa operates a childhood cancer registry on the national level.

Researchers brought together data from 16 of the smaller, local registries, collecting this information for the first time and presenting it in an accessible format.

The data were published in ecancermedicalscience.

Examining the data in context allowed the researchers to notice trends in cancer incidence. For example, they found that, in Blantyre, Malawi’s second-largest city, the cumulative risk of a child developing Burkitt lymphoma is 2 in every thousand.

The researchers called this incidence “remarkable” and noted that the global research community is largely unaware of this.

“Everything starts with awareness,” said study author Cristina Stefan, global clinical leader of oncology for Roche Diagnostics International Ltd of Switzerland and director of the African Medical Research and Innovation Institute.

“It is highly necessary to publicize these data, which, at the moment, represent the best image of the malignant disease in children in the respective regions.”

The researchers also noted that factors such as the prevalence of malaria and the Epstein-Barr virus contribute to the unique epidemiology of childhood cancer in Africa.

“Our colleagues can learn that the patterns and distribution of cancers in Africa are totally different from Europe, and there is a need for further research into the roles of factors such as genetic predispositions and the influence of infections and other comorbidities in the evolution of cancer,” Dr Stefan said.

“We have learned many universal lessons about data collection as we prepared this work. Our hope is that the publication of this monograph will open the forums for future discussions and that the work will be referenced for the better understanding of cancer in children in Africa and used to improve outcomes for children affected there.”

ASCO updates guidelines on antiemetic use in cancer patients

The American Society of Clinical Oncology (ASCO) has updated its clinical practice guidelines on the use of antiemetics in cancer patients.

The update, published in the Journal of Clinical Oncology, provides new evidence-based information on the appropriate use of olanzapine, NK1 receptor antagonists, and dexamethasone.

“The adverse impact of inadequately controlled nausea and vomiting on patients’ quality of life is well documented,” said Paul J. Hesketh, MD, co-chair of the ASCO expert panel that updated the guidelines.

“By following the ASCO antiemetics guideline, clinicians have the opportunity to improve patients’ quality of life by minimizing treatment-induced emesis.”

To update ASCO’s guidelines on antiemetics, the expert panel conducted a systematic review of the medical literature published between November 2009 and June 2016. The panel included members with expertise in medical oncology, radiation oncology, nursing, pharmacy, and health services research, as well as a patient representative.

“Tremendous progress has been realized over the last 25 years in the prevention of chemotherapy-induced nausea and vomiting with the introduction of new classes of antiemetic agents,” said Mark G. Kris, MD, co-chair of the expert panel that updated the guidelines.

“The full benefit of these treatment advances will only be realized, however, if evidence-based guidelines are fully implemented.”

Key recommendations in the updated guidelines include:

For adults receiving chemotherapy with a high risk for nausea and vomiting (eg, cisplatin or the combination of cyclophosphamide and an anthracycline), olanzapine should be added to standard antiemetic regimens (the combination of a 5-HT3 receptor antagonist, an NK1 receptor antagonist, and dexamethasone). Olanzapine also helps individuals who experience symptoms despite receiving medicines to prevent vomiting before chemotherapy is given.

For adults receiving carboplatin-based chemotherapy or high-dose chemotherapy and children receiving chemotherapy with a high risk for nausea and vomiting, an NK1 receptor antagonist should be added to the standard antiemetic regimen (the combination of 5-HT3 receptor antagonist and dexamethasone).

Dexamethasone treatment can be limited to the day of chemotherapy administration in patients receiving an anthracycline and cyclophosphamide.

Dronabinol and nabilone, cannabinoids approved by the US Food and Drug Administration, can be used to treat nausea and vomiting that is resistant to standard antiemetic therapies. Evidence remains insufficient to recommend medical marijuana for either prevention or treatment of nausea and vomiting in patients with cancer receiving chemotherapy or radiation therapy.

To update ASCO’s guidelines on antiemetics, the expert panel conducted a systematic review of the medical literature published between November 2009 and June 2016. The panel included members with expertise in medical oncology, radiation oncology, nursing, pharmacy, and health services research, as well as a patient representative.

“Tremendous progress has been realized over the last 25 years in the prevention of chemotherapy-induced nausea and vomiting with the introduction of new classes of antiemetic agents,” said Mark G. Kris, MD, co-chair of the expert panel that updated the guidelines.

“The full benefit of these treatment advances will only be realized, however, if evidence-based guidelines are fully implemented.”

Key recommendations in the updated guidelines include:

For adults receiving chemotherapy with a high risk for nausea and vomiting (eg, cisplatin or the combination of cyclophosphamide and an anthracycline), olanzapine should be added to standard antiemetic regimens (the combination of a 5-HT3 receptor antagonist, an NK1 receptor antagonist, and dexamethasone). Olanzapine also helps individuals who experience symptoms despite receiving medicines to prevent vomiting before chemotherapy is given.

For adults receiving carboplatin-based chemotherapy or high-dose chemotherapy and children receiving chemotherapy with a high risk for nausea and vomiting, an NK1 receptor antagonist should be added to the standard antiemetic regimen (the combination of 5-HT3 receptor antagonist and dexamethasone).

Dexamethasone treatment can be limited to the day of chemotherapy administration in patients receiving an anthracycline and cyclophosphamide.

Dronabinol and nabilone, cannabinoids approved by the US Food and Drug Administration, can be used to treat nausea and vomiting that is resistant to standard antiemetic therapies. Evidence remains insufficient to recommend medical marijuana for either prevention or treatment of nausea and vomiting in patients with cancer receiving chemotherapy or radiation therapy.

FDA grants drug breakthrough designation for AML

First month’s supply of venetoclax

The US Food and Drug Administration (FDA) has granted breakthrough therapy designation to venetoclax (Venclexta®).

The designation is for venetoclax in combination with low-dose cytarabine to treat elderly patients with previously untreated acute myeloid leukemia (AML) who are ineligible for intensive chemotherapy.

The FDA’s breakthrough designation is intended to expedite the development and review of new treatments for serious or life-threatening conditions.

Breakthrough designation entitles the company developing a therapy to more intensive FDA guidance on an efficient and accelerated development program, as well as eligibility for other actions to expedite FDA review, such as a rolling submission and priority review.

To earn breakthrough designation, a treatment must show encouraging early clinical results demonstrating substantial improvement over available therapies with regard to a clinically significant endpoint, or it must fulfill an unmet need.

About venetoclax

Venetoclax is a small molecule designed to selectively bind and inhibit the BCL-2 protein. The drug is being developed by AbbVie and Roche.

Last year, the FDA granted venetoclax accelerated approval to treat patients with chronic lymphocytic leukemia who have 17p deletion and have received at least one prior therapy. Continued approval of venetoclax for this indication may be contingent upon verification of clinical benefit in confirmatory trials.

The FDA granted venetoclax breakthrough therapy designation for the AML indication based on data from an ongoing phase 1/2 study. Preliminary data from the study were presented at the 22nd European Hematology Association (EHA) Annual Congress.

The presentation included data on 61 elderly patients (older than 65) with previously untreated AML who were ineligible for intensive chemotherapy.

They received venetoclax in combination with low-dose cytarabine (as well as prophylaxis for tumor lysis syndrome). The patients’ median time on treatment was 6 months (range, <1 to 19 months), and 72% of patients discontinued treatment.

The overall response rate was 65%. Twenty-five percent of patients achieved a complete response, 38% had a complete response with incomplete blood count recovery, and 2% had a partial response.

The 30-day death rate was 3%, the 60-day death rate was 15%, and the median overall survival was approximately 12 months.

The most common adverse events of any grade (occurring in at least 30% of patients) were nausea (74%), hypokalemia (46%), diarrhea (46%), fatigue (44%), decreased appetite (41%), constipation (34%), hypomagnesemia (34%), vomiting (31%), thrombocytopenia (44%), febrile neutropenia (38%), and neutropenia (33%).

Grade 3/4 adverse events (occurring in at least 10% of patients) included thrombocytopenia (44%), febrile neutropenia (36%), neutropenia (33%), anemia (28%), hypokalemia (16%), hypophosphatemia (13%), and hypertension (12%).

Developing better mouse models

Developing better mouse models

Researchers say they have developed a new approach to model human immune variation that overcomes the limitations of traditional mouse models.

With this approach, the team identified genetic markers that directly correlate with the outcome of inflammatory and malignant diseases in humans, including chronic lymphocytic leukemia and Burkitt lymphoma.

The findings suggest that accounting for immune diversity is critical to the success of predicting disease outcomes based on immune cell measurements.

The team reported these findings in Nature Communications.

Traditionally, researchers have relied on inbred mouse strains to gain insight into human diseases while reducing experimental noise.

“If you take a black, a brown, or a white mouse, each one will give you a different answer in the same assay,” said Klaus Ley, MD, of La Jolla Institute for Allergy and Immunology in California.

“For example, if you vaccinate them, their responses will be different, which creates a lot of experimental noise. However, when you think about patients, or even healthy people, we are all different.”

To mine those differences for information, the researchers embraced the experimental noise. Instead of analyzing a single inbred mouse strain, they turned to the hybrid mouse diversity panel (HDMP).

The HDMP is a panel of about 100 different inbred mouse strains that mirror the breadth of genetic and immunological diversity found in the human population.

The researchers studied the natural variation in the activation pattern of abdominal macrophages. Macrophages isolated from 83 different mouse strains from the HDMP were exposed to lipopolysaccharide (LPS), a major component of the outer wall of gram-negative bacteria.

“Fundamentally, when the immune system is confronted with gram-negative bacteria, it can deal with the situation in 2 ways—either it gets very angry and tries to kill the bacteria or it can wall them off in an attempt to live with it,” explained Dr Ley. “Both strategies carry a certain risk, but a long evolutionary history has ensured that mice and people can survive with either strategy.”

The LPS-induced reactions of the macrophages covered the whole spectrum—from very aggressive (LPS+) to very tolerant (LPS-), depending on the mouse strain.

Next, the researchers asked which genes were active during each type of response to identify gene signatures that correlated with LPS responsiveness.

The team then ran these gene signatures across various human gene expression data sets and discovered they strongly correlated with human disease outcomes.

For example, macrophages isolated from healthy joints were enriched in LPS-tolerant genes, whereas macrophages from rheumatoid arthritis patients were strongly skewed toward LPS-aggressive.

Since it was known that mice and people with the aggressive phenotype are better at fighting cancer, the researchers specifically asked whether the level of LPS responsiveness could predict tumor survival.

After analyzing data from 18,000 biopsies across 39 different tumor types, the team found the LPS+ gene signature strongly correlated with survival, while the LPS- signature correlated with cancer death.

The pattern was significant across many types of cancer, including chronic lymphocytic leukemia, Burkitt lymphoma, osteosarcoma, melanoma, and large-cell lung carcinoma.
