Zanubrutinib receives breakthrough designation for MCL
The (MCL) who have received at least one prior therapy.
Zanubrutinib (BGB-3111) is a Bruton’s tyrosine kinase inhibitor being developed by BeiGene as a potential treatment for B-cell malignancies.
Researchers have evaluated zanubrutinib in a phase 2 trial (NCT03206970) of patients with relapsed/refractory MCL. Results from this trial were presented at the 2018 annual meeting of the American Society of Hematology (Abstract 148).
As of March 27, 2018, 86 patients had been enrolled in the trial and received treatment. They had a median of two prior lines of therapy and they received zanubrutinib at 160 mg twice daily.
Eighty-five patients were evaluable for efficacy. The overall response rate was 83.5% (71/85), and the complete response rate was 58.8% (50/85). At a median follow-up of 24.1 weeks, the median duration of response and median progression-free survival had not been reached. The estimated 24-week progression-free survival rate was 82%. The most common adverse events (AEs) in this trial were decrease in neutrophil count (31.4%), rash (29.1%), upper respiratory tract infection (29.1%), and decrease in platelet count (22.1%). Common grade 3 or higher AEs included neutrophil count decrease (11.6%) and lung infection (5.8%).
Four patients had fatal treatment-emergent AEs. One death was caused by a traffic accident, one was due to cerebral hemorrhage, and one resulted from pneumonia. The fourth death occurred in a patient with infection, but the cause of death was unknown.
Breakthrough therapy designation is designed to expedite the development and review of a therapy for a serious or life-threatening disease, following preliminary clinical evidence indicating it demonstrates substantial improvement over existing therapies.

FDA labeling templates smooth way for OTC naloxone
Drug facts labels (DFLs) are required for all OTC drugs, and it’s usually up to manufacturers to develop and test their own to ensure that consumers understand how to use their products.
“Some stakeholders have identified the requirement ... as a barrier to development of OTC naloxone products,” so the agency developed two DFLs on its own – one for nasal spray naloxone, the other for auto-injectors – and completed the necessary label comprehension testing, according to an announcement from FDA Commissioner Scott Gottlieb, MD.
There’s not much else manufactures have to do, except deal with the details of their own products. They “can now focus their efforts on ... how well consumers understand the product-specific information that hasn’t been already tested in the model” DFLs, according to the announcement.
As deaths from opioid abuse continue to climb, the FDA is committed to increasing access to naloxone, which currently requires a prescription. The new DFLs “should jump-start the development of OTC naloxone products ... I personally urge companies to take notice of this pathway that the FDA has opened for them and come to the Agency with applications as soon as possible,” Dr. Gottlieb said.
Comprehension was assessed in more than 700 people, including heroin and prescription opioid users, their friends and families, and adolescents. “Overall, the study demonstrated that” the DFLs are “well-understood by consumers” and acceptable “for use by manufacturers in support of their ... development programs,” according to the announcement.
In a press statement, the American Medical Association applauded the agency’s move “to provide labeling that would allow for over-the-counter availability of naloxone, a move that will save people from opioid-related overdose ... The action should spur efforts by naloxone manufacturers to submit applications for their products to receive over-the-counter status.”

FDA approves cabozantinib for previously treated HCC
The Food and Drug Administration has approved cabozantinib tablets (Cabometyx) for patients with hepatocellular carcinoma (HCC) who have been previously treated with sorafenib.
Approval was based on an improvement in overall survival over placebo seen in the phase 3 CELESTIAL trial for patients with advanced HCC who received prior sorafenib.
Median overall survival was 10.2 months with cabozantinib versus 8.0 months with placebo (hazard ratio, 0.76; 95% confidence interval, 0.63-0.92; P = .0049). Median progression-free survival was 5.2 months with cabozantinib and 1.9 months with placebo (HR, 0.44; 95% CI, 0.36-0.52; P less than .0001). Objective response rates were 4% with cabozantinib and 0.4% with placebo (P = .0086), Exelixis, makers of the drug, said in a press release.
The most common grade 3 or 4 adverse events in the patients who received cabozantinib, compared with those who received placebo, were palmar-plantar erythrodysesthesia (17% vs. 0%), hypertension (16% vs. 2%), increased aspartate aminotransferase (12% vs. 7%), fatigue (10% vs. 4%), and diarrhea (10% vs. 2%). Treatment-related grade 5 adverse events occurred in six patients in the cabozantinib group (hepatic failure, esophagobronchial fistula, portal vein thrombosis, upper gastrointestinal hemorrhage, pulmonary embolism, and hepatorenal syndrome) and in one patient in the placebo group (hepatic failure).
Cabozantinib is also approved to treat renal cell carcinoma and medullary thyroid cancer.
Checkpoint inhibitor pembrolizumab was granted accelerated approval for the same HCC indication – to treat patients who have been previously treated with sorafenib – in late 2018.
Exelixis and its partner Ipsen have launched a phase 3 trial of cabozantinib in combination with the checkpoint inhibitor atezolizumab versus sorafenib in previously untreated advanced HCC. The trial will also explore single-agent activity of cabozantinib in the first-line setting, the company said in the press release.

Flu season showing signs of decline
The 2018-2019 flu season may have peaked as measures of influenza-like illness (ILI) activity dropped in the first week of the new year, according to the U.S. Centers for Disease Control and Prevention.
The proportion of outpatients visits for ILI dropped to 3.5% for the week ending Jan. 5, 2019, after reaching 4.0% the previous week. Outpatient ILI visits first topped the national baseline of 2.2% during the week ending Dec. 8, 2018, and have remained above that value for 5 consecutive weeks, the CDC’s influenza division said on Jan. 11.
Flu activity reported by the states reflects the national drop: 10 states came in at level 10 on the CDC’s 1-10 scale of activity for the week ending Jan. 5 – down from 12 the week before – and a total of 15 were in the high range from 8 to 10, compared with 19 the previous week, the CDC said. Two states, Mississippi and Texas, dropped from level 10 to level 7, which the CDC categorizes as moderate activity.
A total of 73 ILI-related deaths were reported during the week ending Dec. 29 (the latest with data available; reporting less than 68% complete), which already exceeds the 71 deaths reported for the week ending Dec. 22 (reporting 85% complete). Flu deaths totaled 437 through the first 13 weeks of the 2018-2019 season, compared with the 1,659 that occurred during weeks 1-13 of the very severe 2017-2018 season, CDC data show.
For the week ending Jan. 5, the CDC received reports of three flu-related pediatric deaths, all of which occurred the previous week. For the season so far, there have been 16 pediatric deaths, compared with 20 at this point in the 2017-2018 season.
Estimates released during the flu season for the first time show that between 6 and 7 million Americans have been infected since Oct. 1, 2018, and that 69,000-84,000 people have been hospitalized with the flu through Jan. 5, 2019. These cumulative totals have previously been available only at the end of the season, the CDC noted.

Sickle cell infusion gains FDA breakthrough designation
The in patients with sickle cell disease of all genotypes.
The designation allows the treatment to be reviewed on an expedited schedule.
Crizanlizumab, marketed by Novartis, is a humanized anti–P-selectin monoclonal antibody that has been shown to inhibit interactions between endothelial cells, platelets, red blood cells, sickled red blood cells, and leukocytes.
In the phase 2 SUSTAIN trial, crizanlizumab reduced the median annual rate of vasoocclusive crises that resulted in health care visits by about 45%, compared with placebo (1.63 vs. 2.98; P = .010). The drug also increased the percentage of patients who did not experience any vasoocclusive crises, compared with placebo (35.8% vs. 16.9%; P = .010).
The rates of treatment-emergent and serious adverse events was similar in the drug and placebo arms of the trial.

FDA approves new ALL treatment for children, young adults
The in pediatric and young adult patients aged 1 month to 21 years.
Calaspargase pegol-mknl is an asparagine-specific enzyme intended to provide a longer interval between doses, compared with other available pegaspargase products. The recommended dosage of calaspargase pegol-mknl is 2,500 units/m2 given no more frequently than every 21 days.
The FDA said it approved calaspargase pegol-mknl because the drug maintained nadir serum asparaginase activity above the level of 0.1 U/mL when given at 2,500 U/m2 every 3 weeks.
Calaspargase pegol-mknl was evaluated in Study DFCI 11-001, a trial of 237 children and adolescents with newly diagnosed ALL or lymphoblastic lymphoma. The patients’ median age was 5 years.
Study participants received calaspargase pegol-mknl at 2,500 U/m2 (n = 118) or pegaspargase at 2,500 U/m2 (n = 119) as part of a Dana-Farber Cancer Institute ALL Consortium backbone therapy. The median duration of exposure was 8 months for both calaspargase pegol-mknl and pegaspargase. Among the patients with B-cell lineage ALL, the complete remission rate was 98% in the calaspargase pegol-mknl arm and 99% in the pegaspargase arm. Estimated overall survival rates were comparable between the arms.
Common grade 3 or higher adverse events in the calaspargase pegol-mknl and pegaspargase arms included elevated transaminase (52% and 66%, respectively), bilirubin increase (20% and 25%), pancreatitis (18% and 24%), and abnormal clotting studies (14% and 21%). There was one fatal adverse event among patients on calaspargase pegol-mknl – multiorgan failure in the setting of chronic pancreatitis associated with a pancreatic pseudocyst.
The safety of calaspargase pegol-mknl was also evaluated in Study AALL07P4, a trial of patients with newly diagnosed, high-risk B-precursor ALL. The patients received calaspargase pegol-mknl at 2,500 U/m2 (n = 43) or 2,100 U/m2 (n = 68) or pegaspargase at 2,500 U/m2 (n = 52) as a component of an augmented Berlin-Frankfurt-Münster regimen. The patients’ median age was 11 years. The median duration of exposure was 7 months for both calaspargase pegol-mknl and pegaspargase. There were 3 induction deaths among the 111 patients who received calaspargase pegol-mknl (2.8%) but no induction deaths among the 52 patients treated with pegaspargase.

The FDA said it approved calaspargase pegol-mknl because the drug maintained nadir serum asparaginase activity above the level of 0.1 U/mL when given at 2,500 U/m2 every 3 weeks.
Calaspargase pegol-mknl was evaluated in Study DFCI 11-001, a trial of 237 children and adolescents with newly diagnosed ALL or lymphoblastic lymphoma. The patients’ median age was 5 years.
Study participants received calaspargase pegol-mknl at 2,500 U/m2 (n = 118) or pegaspargase at 2,500 U/m2 (n = 119) as part of a Dana-Farber Cancer Institute ALL Consortium backbone therapy. The median duration of exposure was 8 months for both calaspargase pegol-mknl and pegaspargase. Among the patients with B-cell lineage ALL, the complete remission rate was 98% in the calaspargase pegol-mknl arm and 99% in the pegaspargase arm. Estimated overall survival rates were comparable between the arms.
Common grade 3 or higher adverse events in the calaspargase pegol-mknl and pegaspargase arms included elevated transaminase (52% and 66%, respectively), bilirubin increase (20% and 25%), pancreatitis (18% and 24%), and abnormal clotting studies (14% and 21%). There was one fatal adverse event among patients on calaspargase pegol-mknl – multiorgan failure in the setting of chronic pancreatitis associated with a pancreatic pseudocyst.
The safety of calaspargase pegol-mknl was also evaluated in Study AALL07P4, a trial of patients with newly diagnosed, high-risk B-precursor ALL. The patients received calaspargase pegol-mknl at 2,500 U/m2 (n = 43) or 2,100 U/m2 (n = 68) or pegaspargase at 2,500 U/m2 (n = 52) as a component of an augmented Berlin-Frankfurt-Münster regimen. The patients’ median age was 11 years. The median duration of exposure was 7 months for both calaspargase pegol-mknl and pegaspargase. There were 3 induction deaths among the 111 patients who received calaspargase pegol-mknl (2.8%) but no induction deaths among the 52 patients treated with pegaspargase.
Additional details on these studies and calaspargase pegol-mknl can be found in the drug’s prescribing information. Calaspargase pegol-mknl is a product of Servier.
Flu season intensifies: High activity now in 19 states
The effects of the flu became much more widespread in the last full week of 2018 as the number of states with a high level of influenza activity more than doubled from the week before, according to the Centers for Disease Control and Prevention.
A total of 19 states were in the high range (8-10) on the CDC’s 1-10 scale of influenza-like illness (ILI) activity for the week ending Dec. 29, compared with 9 states the week before, the CDC’s influenza division reported Jan. 4. Of those 19 most-affected states, 12 were at level 10, 1 was at level 9, and 6 were at level 8. Geographic distribution of the virus was reported to be widespread in 24 states, the CDC said.
The proportion of outpatient visits for ILI – defined as fever (temperature of 100° F or greater) and cough and/or sore throat – rose to 4.1% for the week, which was up from 3.3% the previous week and well above the national baseline of 2.2%.
“The increase in the percentage of patient visits for ILI may be influenced in part by a reduction in routine health care visits during the winter holidays,” the report noted. There were 38 influenza deaths reported for the most recent week with available data (the week ending Dec. 22), although reporting for that week was just over 54% complete as of Jan. 4. For the previous weeks, 39 flu-related deaths occurred during the week ending Dec. 15 (reporting 84% complete) and 43 deaths during the week ending Dec. 8 (reporting 94% complete). For the respective weeks of last year’s flu season, total deaths were 359, 165, and 118, CDC data show.
For the week ending Dec. 29, two pediatric deaths were reported, one of which occurred the week before. For the 2018-2019 season so far, 13 flu-related pediatric deaths have been reported, the CDC said.

Synthetic opioids drive spike in U.S. fatal drug overdoses
New federal statistics suggest that the opioid epidemic in the United States is evolving as physicians crack down on the use of prescription painkillers: Fatal drug overdose deaths rose by 12% from 2016 to 2017, boosted by a wave of fatalities linked to illicit synthetic opioids like fentanyl that are now linked to an estimated 60% of opioid-related deaths.
“Overall, the overdose epidemic continues to worsen, and it has grown increasingly complex by coinvolvement of prescription and illicit drugs,” Lawrence Scholl, PhD, MPH, and his associates at the Centers for Disease Control & Prevention wrote in the Morbidity and Mortality Weekly Report.
The new statistics provide more evidence that 2017 marked “a sharp increase in what has characterized as the third wave of the opioid epidemic,” said drug and health policy researcher Stephen Crystal, PhD, of Rutgers University, New Brunswick, N.J., in an interview. He was referring to a wave that experts believe started in 2013 amid a spike in U.S. overdose deaths from fentanyl and other synthetic opioids.
The new report analyzes fatal drug overdose data from 2013 to 2017. According to the findings, the total number of those overdoses rose to 70,237 in 2017, up from 63,632 in 2016. The highest drug overdose death rates in 2017 were in West Virginia, followed by Ohio, Pennsylvania, and the District of Columbia.
Some statistics did not change much from 2016 to 2017: About two-thirds of the drug overdose deaths were linked to opioids in both years, and the death rate of cases linked to prescription drugs and heroin remained steady. (Death rates in the report were age adjusted.)
However, the percentage of fatal overdose cases linked to synthetic opioids grew 45% from 2016 to 2017. Overall, 60% of opioid-related fatal overdoses in 2017 involved synthetic opioids.
The report identifies increases in several areas from 2016 to 2017. Opioid-related drug overdose deaths among black people rose by 25%, and an analysis of data from 34 states and the District of Columbia found the highest increases in death rates in North Carolina (29%), Ohio (19%), and Maine (19%).
In regard to deaths linked to synthetic opioids specifically, the highest death rates in 2017 were in West Virginia (37 per 100,000), Ohio (32 per 100,000), and New Hampshire (30 per 100,000).
“Part of what we’re seeing in these increased numbers are individuals who have pain, can’t get prescribed opioids, and turn to street drugs,” Dr. Crystal said, adding that “abruptly cutting patients off is not good, and leaving patients with a lot of untreated pain is not good. If people are going to be discontinued [from opioids] or have their doses reduced, the taper needs to be done very slowly and carefully.”
Synthetic opioids were not the only drugs that are driving up fatal overdoses, as the death rates of cases linked to cocaine and psychostimulants (such as methamphetamine) jumped by more than a third in 2017.
“The most important thing these numbers are telling me is that it’s becoming more and more attractive to drug dealers to put fentanyl in the heroin, cocaine, and other drugs they sell,” Dr. Crystal said. “When that happens, dependence on street drugs becomes much more deadly. It’s almost impossible to get the dose right. Every time you shoot up, you’re taking a chance that you’ll overdose.”
The report had limitations, including the fact that details about drug use were missing from 12% (2016) and 15% (2017) of death certificates in fatal overdose cases. By state, the percentages of those death certificates that included drug information ranged from as little as 55% to 99%.
There’s some possible positive news: The report points to preliminary data from 2018 suggesting that the number of annual drug overdose deaths may be leveling off – although it says more analysis is needed to confirm the trend.
Dr. Crystal, however, is not celebrating. “I don’t see this as a good news story, really,” he said, adding that there’s “a little too much of people patting themselves on the back” because they’re proud of cutbacks in opioid prescriptions.
“This doesn’t have to do with the huge number of people who got started with opioids years ago” and are now at risk of using street drugs, he said. “We haven’t engaged that population at the rate we need to. And flattening out at 70,000 drug overdoses a year is not a good news story.”
Dr. Crystal reported no relevant disclosures.

FDA expands dasatinib indication to children with Ph+ ALL
The .
The tyrosine kinase inhibitor is now approved for use in combination with chemotherapy to treat pediatric patients aged 1 year and older who have newly diagnosed, Philadelphia-chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL).
Dasatinib is already approved for use in children aged 1 year and older who have chronic phase, Ph+ chronic myeloid leukemia (CML).
In adults, dasatinib is approved to treat newly diagnosed, Ph+, chronic phase CML; chronic, accelerated, or myeloid/lymphoid blast phase, Ph+ CML with resistance or intolerance to prior therapy including imatinib; and Ph+ ALL with resistance or intolerance to prior therapy. The approval in children with Ph+ ALL is based on data from a phase 2 study (CA180-372, NCT01460160).
In this trial, researchers evaluated dasatinib in combination with the AIEOP-BFM ALL 2000 multi-agent chemotherapy protocol in patients (aged 1-17 years) with newly diagnosed, B-cell precursor, Ph+ ALL.
There were 78 patients evaluated for efficacy in cohort 1. They received dasatinib at a daily dose of 60 mg/m2 for up to 24 months.
Patients with central nervous system 3 disease received cranial irradiation, and patients were assigned to stem cell transplant based on minimal residual disease if they were thought to have a high risk of relapse.
The 3-year event-free survival rate in the 78 patients was 64.1%.
There were 81 patients evaluable for safety who received dasatinib continuously in combination with chemotherapy. Their median duration of treatment was 24 months.
The most common adverse events (AEs) in these patients were mucositis, febrile neutropenia, pyrexia, diarrhea, nausea, vomiting, musculoskeletal pain, abdominal pain, cough, headache, rash, fatigue, and constipation.
Eight patients (10%) had AEs leading to treatment discontinuation. These included fungal sepsis, hepatotoxicity in the setting of graft-versus-host disease, thrombocytopenia, cytomegalovirus infection, pneumonia, nausea, enteritis, and drug hypersensitivity.
Three patients (4%) had fatal AEs, all infections.
This trial was sponsored by Bristol-Myers Squibb. Additional data are available in the prescribing information for dasatinib.

CDC: Flu activity ‘high’ in nine states
according to the Centers for Disease Control and Prevention.
Patients with ILI made up an estimated 3.3% of outpatient visits for the week, which is up from 2.7% the previous week and well above the baseline rate of 2.2%, which the 2018-2019 flu season has now exceeded for the past 3 weeks, the CDC reported Dec. 28. ILI is defined “as fever (temperature of 100°F [37.8°C] or greater) and cough and/or sore throat.”
Three states – Colorado, Georgia, and New Mexico – are now at the highest level of flu activity on the CDC’s 1-10 scale, and nine states are in the “high” range (8-10), compared with two states in high range (both at level 10) for the week ending Dec. 15. Another seven states and Puerto Rico are now in the “moderate” range of 6-7, data from the CDC’s Outpatient ILI Surveillance Network show.
Four flu-related deaths in children were reported during the week ending Dec. 22, two of which occurred in previous weeks, which brings the total to 11 for the 2018-2019 season, the CDC reported.
