The US Food and Drug Administration (FDA) has expanded the approved use of brentuximab vedotin (BV, ADCETRIS).

BV is now approved for adults with primary cutaneous anaplastic large-cell lymphoma (pcALCL) and CD30-expressing mycosis fungoides (MF) who have received prior systemic therapy.

This is the fourth FDA-approved indication for BV. The drug has regular approval for 2 indications in classical Hodgkin lymphoma and accelerated approval for the treatment of systemic ALCL.

In November 2016, the FDA granted BV breakthrough therapy designation for the treatment of patients with pcALCL and CD30-expressing MF who require systemic therapy and have received one prior systemic therapy. The agency also granted the supplemental biologics license application priority review.

The approval for BV in pcALCL and CD30-expressing MF is based on data from the phase 3 ALCANZA trial and a pair of phase 2 investigator-sponsored trials.

Phase 3 trial

Results from ALCANZA were presented at the 9th Annual T-cell Lymphoma Forum in January and published in The Lancet in June.

There were 128 patients in the intent-to-treat and safety populations. Sixty-four patients (48 with MF and 16 with pcALCL) were randomized to receive BV at 1.8 mg/kg every 3 weeks for up to 48 weeks.

The other 64 patients (49 with MF and 15 with pcALCL) were randomized to receive standard of care (SOC)—methotrexate at 5 mg to 50 mg weekly or bexarotene at a target dose of 300 mg/m² daily for up to 48 weeks.

The study’s primary endpoint was the rate of objective response lasting at least 4 months (ORR4). The ORR4 rate was significantly higher with BV than with SOC—56.3% and 12.5%, respectively (P<0.0001).

For patients with MF, the ORR4 was 50% with BV and 10% with SOC. For patients with pcALCL, the ORR4 was 75% with BV and 20% with SOC.

Overall, the complete response (CR) rates were 15.6% in the BV arm and 1.6% in the SOC arm (P=0.0046).

For patients with MF, the CR rate was 10% with BV and 0% with SOC. For patients with pcALCL, the CR rate was 31% with BV and 7% with SOC.

Progression-free survival (PFS) was significantly longer in the BV arm than the SOC arm. The median PFS was 16.7 months and 3.5 months, respectively. The hazard ratio was 0.270 (P<0.0001).

For patients with MF, the median PFS was 15.9 months with BV and 3.5 months with SOC. For patients with pcALCL, the median PFS was 27.5 months with BV and 5.3 months with SOC.

The most common adverse events (AEs) of any grade (occurring in 15% or more of patients in the BV and SOC arms, respectively) were peripheral neuropathy (67% and 6%), nausea (36% and 13%), diarrhea (29% and 6%), fatigue (29% and 27%), vomiting (17% and 5%), alopecia (15% and 3%), pruritus (17% and 13%), pyrexia (17% and 18%), decreased appetite (15% and 5%), and hypertriglyceridemia (2% and 18%).

Phase 2 trials

Data from the investigator-sponsored trials were published in the Journal of Clinical Oncology in 2015.

The first study was published in July of that year. The trial enrolled 32 patients with MF or Sézary syndrome. Thirty patients were evaluable for efficacy, and more than half had received 3 or more prior systemic therapies.

Patients received BV (1.8 mg/kg) every 3 weeks for a maximum of 16 doses. The primary endpoint was objective clinical response rate.

Seventy percent of patients (21/30) achieved an objective response across all stages of disease. One patient had a CR, 20 had a partial response, 4 had stable disease, 5 had progressive disease, and 2 were not evaluable for response.

The most common related AEs of any grade were peripheral neuropathy (66%), fatigue (47%), nausea (28%), hair loss (22%), and neutropenia (19%). Grade 3/4 related AEs included neutropenia (n=4), rash (n=3), and peripheral neuropathy (n=1).

The second phase 2 trial was published in August 2015. This trial enrolled CD30-positive patients with lymphomatoid papulosis (LyP), pcALCL, and MF.

Fifty-four patients were enrolled, and 48 were evaluable at the time of analysis. Patients had received an infusion of BV (1.8 mg/kg) every 21 days.

Seventy-three percent of patients (35/48) achieved an objective response, including 100% (20/20) with LyP and/or pcALCL and 54% (15/28) with MF. The CR rate was 35% (n=17).

The most common AEs were peripheral neuropathy (67%), fatigue (35%), skin rash (24%), diarrhea (15%), muscle pain (17%), localized skin infection (15%), neutropenia (15%), and hair loss (11%).

Grade 3/4 AEs included neutropenia (n=3), nausea (n=2), unstable angina or myocardial infarction (n=2), infection (n=2), joint pain (n=2), fatigue (n=1), deep vein thrombosis (n=1), pulmonary embolism (n=1), aminotransferase elevation (n=1), and dehydration (n=1).

The US Food and Drug Administration (FDA) has approved use of an intravenous (IV) formulation of aprepitant (CINVANTI™) to prevent chemotherapy-induced nausea and vomiting (CINV).

CINVANTI is intended to be used in combination with other antiemetic agents to prevent acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic chemotherapy (HEC) and moderately emetogenic chemotherapy (MEC).

CINVANTI is to be used in combination with a 5-HT3 receptor antagonist and dexamethasone.

The full prescribing information is available at www.cinvanti.com.

The US commercial launch of CINVANTI is planned for January 2018.

CINVANTI is the first IV formulation to directly deliver aprepitant, a substance P/neurokinin-1 (NK1) receptor antagonist.

Aprepitant is also the active ingredient in EMEND^® capsules, which were approved by the FDA in 2003. EMEND IV^®, which was approved in 2008, contains aprepitant’s prodrug, fosaprepitant.

Heron Therapeutics, Inc., developed CINVANTI in an attempt to provide an IV formulation of aprepitant that has the same efficacy as IV fosaprepitant but does not pose the risk of adverse events (AEs) related to polysorbate 80.

“Aprepitant has long been the standard in the NK1 class, and it remains the only single-agent NK1 with proven efficacy in preventing CINV in both the acute and delayed phases in HEC and MEC,” said Rudolph M. Navari, MD, PhD, of the University of Alabama Birmingham School of Medicine.

“Because CINVANTI is a novel, polysorbate 80-free, IV formulation of aprepitant, it enables physicians to provide patients with standard-of-care efficacy without the potential risk of polysorbate 80-related adverse events, such as infusion-site reactions.”

The FDA approved CINVANTI based on data demonstrating the bioequivalence of CINVANTI to EMEND IV.

A phase 1, randomized, 2-way cross-over study comparing the drugs enrolled 100 healthy subjects. The subjects received CINVANTI at 130 mg or EMEND IV at 150 mg, given over 30 minutes on day 1 of periods 1 and 2.

The researchers said 90% confidence intervals for CINVANTI AUC_0-t (area under the time-concentration curve from time 0 to the last measurable concentration), AUC_0-inf (area under the time-concentration curve from time 0 extrapolated to infinity), and C12h (plasma concentration at 12 hours) “were well within bioequivalence bounds,” which was 80% to 125%.

The team also found the incidence of treatment-emergent AEs was lower with CINVANTI than EMEND IV—21% and 28%, respectively. The same was true for related treatment-emergent AEs—15% and 28%, respectively.

These data were presented at the Hematology/Oncology Pharmacy Association Annual Conference in March/April and the Multinational Association of Supportive Care in Cancer (MASCC)/International Society of Oral Oncology (ISOO) Annual Meeting in June.

The US Food and Drug Administration (FDA) has granted orphan drug designation to artemisone, a product candidate for the treatment of malaria.

Artemisone is a synthetic derivative of the antimalarial drug artemisinin, which “has been optimized for potency, stability, and safety,” according to Artemis Therapeutics, Inc., the company developing artemisone.

The company said phase 2 trial data suggest artemisone is effective against Plasmodium falciparum malaria.

Ninety-five patients were enrolled in the trial, and they received a 2-day or 3-day course of artemisone. Patients also received a second antimalarial drug on the final day of artemisone treatment (in compliance with recommendations from the World Health Organization).

At 28 days, the cure rates were 100% in both the 2-day and 3-day course groups. However, parasite clearance time was 25% faster with the 2-day course.

Artemis Therapeutics, Inc. has not yet released safety data from this trial.

Phase 1 data suggested artemisone was well tolerated by healthy subjects. There were no serious adverse events in the trial and no clinically relevant changes in laboratory and vital parameters, according to researchers.

About orphan designation

The FDA grants orphan designation to products intended to treat, diagnose, or prevent diseases/disorders that affect fewer than 200,000 people in the US.

The designation provides incentives for sponsors to develop products for rare diseases. This may include tax credits toward the cost of clinical trials, prescription drug user fee waivers, and 7 years of market exclusivity if the product is approved.

The European Medicines Agency’s Committee for Medicinal Products for Human Use has granted accelerated assessment to a marketing authorization application (MAA) for CPX-351 (Vyxeos™), a fixed-ratio combination of cytarabine and daunorubicin inside a lipid vesicle.

The MAA is for CPX-351 to treat adults with high-risk acute myeloid leukemia (AML), defined as therapy-related AML or AML with myelodysplasia-related changes.

Accelerated assessment is designed to reduce the review timeline for products of major interest for public health and therapeutic innovation.

“If approved, Vyxeos will become the first new chemotherapy treatment option specifically for European patients with therapy-related AML or AML with myelodysplasia-related changes,” said Karen Smith, MD, PhD, executive vice president, research and development and chief medical officer at Jazz Pharmaceuticals, the company developing and marketing CPX-351.

The MAA for CPX-351 is supported by clinical data from 5 studies, including a phase 3 study. Results from this study were presented at the 2016 ASCO Annual Meeting.

In this study, researchers compared CPX-351 to cytarabine and daunorubicin (7+3) in 309 patients, ages 60 to 75, with newly diagnosed, therapy-related AML or AML with myelodysplasia-related changes.

The complete response rate was 38% in the CPX-351 arm and 26% in the 7+3 arm (P=0.036).

The rate of hematopoietic stem cell transplant was 34% in the CPX-351 arm and 25% in the 7+3 arm.

The median overall survival was 9.6 months in the CPX-351 arm and 5.9 months in the 7+3 arm (P=0.005).

All-cause 30-day mortality was 6% in the CPX-351 arm and 11% in the 7+3 arm. Sixty-day mortality was 14% and 21%, respectively.

Six percent of patients in both arms had a fatal adverse event (AE) on treatment or within 30 days of therapy that was not in the setting of progressive disease.

The rate of AEs that led to discontinuation was 18% in the CPX-351 arm and 13% in the 7+3 arm. AEs leading to discontinuation in the CPX-351 arm included prolonged cytopenias, infection, cardiotoxicity, respiratory failure, hemorrhage, renal insufficiency, colitis, and generalized medical deterioration.

The most common AEs (incidence ≥ 25%) in the CPX-351 arm were hemorrhagic events, 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 European Medicines Agency’s Committee for Medicinal Products for Human Use has granted accelerated assessment to a marketing authorization application (MAA) for CPX-351 (Vyxeos™), a fixed-ratio combination of cytarabine and daunorubicin inside a lipid vesicle.

The MAA is for CPX-351 to treat adults with high-risk acute myeloid leukemia (AML), defined as therapy-related AML or AML with myelodysplasia-related changes.

Accelerated assessment is designed to reduce the review timeline for products of major interest for public health and therapeutic innovation.

“If approved, Vyxeos will become the first new chemotherapy treatment option specifically for European patients with therapy-related AML or AML with myelodysplasia-related changes,” said Karen Smith, MD, PhD, executive vice president, research and development and chief medical officer at Jazz Pharmaceuticals, the company developing and marketing CPX-351.

The MAA for CPX-351 is supported by clinical data from 5 studies, including a phase 3 study. Results from this study were presented at the 2016 ASCO Annual Meeting.

In this study, researchers compared CPX-351 to cytarabine and daunorubicin (7+3) in 309 patients, ages 60 to 75, with newly diagnosed, therapy-related AML or AML with myelodysplasia-related changes.

The complete response rate was 38% in the CPX-351 arm and 26% in the 7+3 arm (P=0.036).

The rate of hematopoietic stem cell transplant was 34% in the CPX-351 arm and 25% in the 7+3 arm.

The median overall survival was 9.6 months in the CPX-351 arm and 5.9 months in the 7+3 arm (P=0.005).

All-cause 30-day mortality was 6% in the CPX-351 arm and 11% in the 7+3 arm. Sixty-day mortality was 14% and 21%, respectively.

Six percent of patients in both arms had a fatal adverse event (AE) on treatment or within 30 days of therapy that was not in the setting of progressive disease.

The rate of AEs that led to discontinuation was 18% in the CPX-351 arm and 13% in the 7+3 arm. AEs leading to discontinuation in the CPX-351 arm included prolonged cytopenias, infection, cardiotoxicity, respiratory failure, hemorrhage, renal insufficiency, colitis, and generalized medical deterioration.

The most common AEs (incidence ≥ 25%) in the CPX-351 arm were hemorrhagic events, 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 most common serious AEs (incidence ≥ 5%) in the CPX-351 arm were dyspnea, myocardial toxicity, sepsis, pneumonia, febrile neutropenia, bacteremia, and hemorrhage.

The US Food and Drug Administration (FDA) has approved ferric citrate (Auryxia) to treat iron-deficiency anemia in adults with chronic kidney disease (CKD) who are not on dialysis.

Ferric citrate was originally approved by the FDA in September 2014 for the control of serum phosphorus levels in patients with CKD who require dialysis.

The full prescribing information for the drug is available at www.Auryxia.com.

“We are pleased with the broad indication permitted by the FDA, as a first-line treatment option for adults with iron-deficiency anemia and chronic kidney disease not on dialysis,” said John Neylan, MD, senior vice president and chief medical officer of Keryx Biopharmaceuticals, Inc., the company marketing ferric citrate.

“Physicians and their patients now have a new treatment option to help manage a serious complication of this complex disease.”

The new approval of ferric citrate was based on results from a 24-week, placebo-controlled, phase 3  trial. Results from this trial were published in the Journal of the American Society of Nephrology in January.

The trial enrolled 234 adults with stage 3-5, non-dialysis-dependent CKD and iron-deficiency anemia. Patients had hemoglobin levels between 9.0 g/dL and 11.5 g/dL and were intolerant to or had an inadequate response to prior treatment with oral iron supplements.

The starting dose of ferric citrate was 3 tablets per day, taken with meals. The mean dose was 5 tablets per day. Patients were not allowed to receive any intravenous or oral iron or erythropoiesis-stimulating agents.

Significantly more patients in the ferric citrate arm than the placebo arm had increases in hemoglobin levels of at least 1 g/dL at any point during the trial’s 16-week efficacy period—52.1% (61/117) and 19.1% (22/115), respectively (P<0.001).

Likewise, significantly more patients in the ferric citrate arm than the placebo arm had a sustained increase in hemoglobin of at least 0.75 g/dL over any 4-week period during the trial—48.7% (n=57) and 14.8% (n=17), respectively (P<0.001).

Serious adverse events occurred in 12.0% of patients in the ferric citrate arm and 11.2% of patients in the placebo arm. There were 2 treatment-emergent deaths in the ferric citrate arm (and none in the placebo arm), but they were not considered drug-related.

The most common (≥5%) treatment-emergent adverse events in patients who received ferric citrate were diarrhea (20.5%), constipation (18.8%), discolored feces (14.5%), nausea (11.1%), abdominal pain (6.0%), and hyperkalemia (6.8%).

The US Food and Drug Administration (FDA) has expanded the approved use of vemurafenib (Zelboraf) to include the treatment of adults who have Erdheim-Chester disease (ECD) with BRAF V600 mutation.

Vemurafenib is a kinase inhibitor designed to inhibit some mutated forms of BRAF.

The drug was already approved by the FDA to treat patients with unresectable or metastatic melanoma with BRAF V600E mutation, as detected by an FDA-approved test.

Now, vemurafenib is the first FDA-approved treatment for ECD.

The FDA previously granted vemurafenib orphan drug and breakthrough therapy designations for this indication, and the supplemental new drug application for vemurafenib in ECD received priority review.

“Today’s approval of Zelboraf for patients with ECD demonstrates how we can apply knowledge of the underlying genetic characteristics of certain malignancies to other cancers,” 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.

“This product was first approved in 2011 to treat certain patients with melanoma that harbor the BRAF V600E mutation, and we are now bringing the therapy to patients with a rare cancer with no approved therapies.”

The application for vemurafenib in ECD was supported by data from the phase 2 VE-BASKET study. Initial results from this study were published in NEJM in August 2015.

VE-BASKET was designed to investigate the use of vemurafenib in patients with BRAF V600 mutation-positive diseases, including ECD.

In the 22 patients with ECD, the best overall response rate was 54.5%. Eleven patients experienced a partial response, and 1 patient achieved a complete response.

The median duration of response, progression-free survival, and overall survival were not reached at a median follow-up of 26.6 months.

The most common adverse events (>50%) were joint pain, rash, hair loss, fatigue, change in heart rhythm, and skin tags. The most common grade 3 or higher adverse events (≥10%) were new skin cancers, high blood pressure, rash, and joint pain.

Cancer drug costs in the US increase substantially after launch, regardless of competition, according to a study published in the Journal of Clinical Oncology.*

Researchers studied 24 cancer drugs approved over the last 20 years and found a mean cumulative cost increase of about 37%, or 19% when adjusted for inflation.

Among drugs approved to treat hematologic malignancies, the greatest inflation-adjusted price increases were for arsenic trioxide (57%), nelarabine (55%), and rituximab (49%).

The lowest inflation-adjusted price increases were for ofatumumab (8%), clofarabine (8%), and liposomal vincristine (18%).

For this study, Daniel A. Goldstein, MD, of Emory University in Atlanta, Georgia, and his colleagues measured the monthly price trajectories of 24 cancer drugs approved by the US Food and Drug Administration. This included 10 drugs approved to treat hematologic malignancies between 1997 and 2011.

To account for discounts and rebates, the researchers used the average sales prices published by the Centers for Medicare and Medicaid Services and adjusted to general and health-related inflation rates. For each drug, the researchers calculated the cumulative and annual drug cost changes.

Results

The mean follow-up was 8 years. The mean cumulative cost increase for all 24 drugs was +36.5% (95% CI, 24.7% to 48.3%).

The general inflation-adjusted increase was +19.1% (95% CI, 11.0% to 27.2%), and the health-related inflation-adjusted increase was +8.4% (95% CI, 1.4% to 15.4%).

Only 1 of the 24 drugs studied had a price decrease over time. That drug is ziv-aflibercept, which was approved to treat metastatic colorectal cancer in 2012.

Ziv-aflibercept was launched with an annual price exceeding $110,000. After public outcry, the drug’s manufacturer, Sanofi, cut the price in half. By the end of the study’s follow-up period in 2017, the cost of ziv-aflibercept had decreased 13% (inflation-adjusted decrease of 15%, health-related inflation-adjusted decrease of 20%).

Cost changes for the drugs approved to treat hematologic malignancies are listed in the following table.

Abbreviations: ALL, acute lymphoblastic leukemia; APL, acute promyelocytic leukemia; CLL, chronic lymphocytic leukemia; MCL, mantle cell lymphoma; MM, multiple myeloma; NHL, non-Hodgkin lymphoma; SD, standard deviation.

The researchers noted that there was a steady increase in drug costs over the study period, regardless of whether a drug was granted a new supplemental indication, the drug had a new off-label indication, or a competitor drug was approved.

The only variable that was significantly associated with price change was the amount of time that had elapsed from a drug’s launch.

This association was significant in models in which the researchers used prices adjusted to inflation (P=0.002) and health-related inflation (P=0.023). However, it was not significant when the researchers used the actual drug price (P=0.085).

The US Food and Drug Administration (FDA) has granted breakthrough therapy designation to GSK2857916, an anti-B-cell maturation antigen (BCMA) monoclonal antibody conjugated to the cytotoxic agent monomethyl auristatin-F via a non-cleavable linker.

The designation is for GSK2857916 as monotherapy for patients with multiple myeloma (MM) who have failed at least 3 prior lines of therapy, including an anti-CD38 antibody, and who are refractory to a proteasome inhibitor and an immunomodulatory agent.

The designation is based on results from a phase 1, dose-escalation and expansion study in patients with relapsed/refractory MM, irrespective of BCMA expression (NCT02064387).

Data from this ongoing trial are scheduled to be presented December 11 in an oral presentation at the 59th Annual Meeting of the American Society of Hematology (ASH) in Atlanta, Georgia.

GSK2857916 has also received orphan drug designation from the FDA and the European Medicines Agency (EMA) as well as PRIME designation from the EMA.

About breakthrough designation

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

Orphan and PRIME designations

The FDA grants orphan designation to therapies intended to treat conditions that affect fewer than 200,000 people in the US. The designation qualifies a drug’s sponsor for various development incentives of the Orphan Drug Act, including tax credits for qualified clinical testing and 7 years of market exclusivity.

In Europe, sponsors who obtain orphan designation for a potential new medicine benefit from a range of incentives, including protocol assistance, access to the centralized procedure, 10 years of market exclusivity, and fee reductions.

The EMA grants PRIME designation to enhance support for the development of medicines that target an unmet medical need. The designation is based on enhanced interaction between sponsor companies and the EMA to optimize development plans and speed up evaluation so these medicines can reach patients earlier.

The designation is based on results from a phase 1, dose-escalation and expansion study in patients with relapsed/refractory MM, irrespective of BCMA expression (NCT02064387).

Data from this ongoing trial are scheduled to be presented December 11 in an oral presentation at the 59th Annual Meeting of the American Society of Hematology (ASH) in Atlanta, Georgia.

GSK2857916 has also received orphan drug designation from the FDA and the European Medicines Agency (EMA) as well as PRIME designation from the EMA.

About breakthrough designation

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

Orphan and PRIME designations

The FDA grants orphan designation to therapies intended to treat conditions that affect fewer than 200,000 people in the US. The designation qualifies a drug’s sponsor for various development incentives of the Orphan Drug Act, including tax credits for qualified clinical testing and 7 years of market exclusivity.

In Europe, sponsors who obtain orphan designation for a potential new medicine benefit from a range of incentives, including protocol assistance, access to the centralized procedure, 10 years of market exclusivity, and fee reductions.

The EMA grants PRIME designation to enhance support for the development of medicines that target an unmet medical need. The designation is based on enhanced interaction between sponsor companies and the EMA to optimize development plans and speed up evaluation so these medicines can reach patients earlier.

The US Food and Drug Administration (FDA) has granted accelerated approval to the BTK inhibitor acalabrutinib (Calquence, formerly ACP-196).

The drug is now approved to treat adults with mantle cell lymphoma (MCL) who have received at least 1 prior therapy.

The FDA’s accelerated approval pathway is used for drugs intended to treat serious conditions where there is unmet medical need and when said drugs have demonstrated effects that suggest they will provide a clinical benefit to patients.

This means further study is required to verify and describe the anticipated clinical benefits of acalabrutinib, which was approved based on the overall response rate observed in a phase 2 trial.

The company developing acalabrutinib, AstraZeneca Pharmaceuticals LP, is currently conducting the necessary additional research.

The FDA previously granted AstraZeneca priority review, breakthrough therapy, and orphan drug designations for acalabrutinib as a treatment for MCL.

Phase 2 trial

The FDA approved acalabrutinib based on results of the phase 2 ACE-LY-004 trial. This single-arm trial enrolled 124 adults with relapsed or refractory MCL.

According to AstraZeneca, acalabrutinib produced an overall response rate of 80%, with 40% of patients achieving a complete response and 40% experiencing a partial response.

The most common adverse events (AEs) of any grade (occurring in at least 20% of patients) were anemia (46%), thrombocytopenia (44%), headache (39%), neutropenia (36%), diarrhea (31%), fatigue (28%), myalgia (21%), and bruising (21%).

Dosage reductions due to AEs occurred in 1.6% of patients. Discontinuations due to AEs occurred in 6.5% of patients. Increases in creatinine 1.5 to 3 times the upper limit of normal occurred in 4.8% of patients.

According to AstraZeneca, full results from ACE-LY-004 have been submitted for presentation at an upcoming medical meeting.

This will be the first MCL trial data to be presented from the acalabrutinib development program, which includes both monotherapy and combination therapies in hematologic and solid tumor malignancies.

The US Food and Drug Administration (FDA) will now recognize 8 European drug regulatory authorities as capable of conducting inspections of manufacturing facilities that meet FDA requirements.

This move is a step toward successful implementation of the amended Pharmaceutical Annex to the 1998 US-European Union (EU) Mutual Recognition Agreement.

This agreement enables US and EU regulators to utilize each other’s good manufacturing practice (GMP) inspections of pharmaceutical manufacturing facilities.

In June, the European Commission determined that the FDA “has the capability, capacity, and procedures in place to carry out GMP inspections at a level equivalent to the EU.”

Now, the FDA has followed suit. The agency said it will rely on inspections of manufacturing facilities conducted by regulatory authorities located in Austria, Croatia, France, Italy, Malta, Spain, Sweden, and the United Kingdom.

“Beginning November 1, we will take the unprecedented and significant step forward in realizing the key benefits of the Mutual Recognition Agreement with our European counterparts in that we will now rely on the inspectional data obtained by these 8 regulatory agencies,” said Dara Corrigan, the FDA’s acting deputy commissioner for global regulatory operations and policy.

“The progress made so far puts us on track to meet our goal of completing all 28 capability assessments in the EU by July 2019.”

The completion of these capability assessments is intended to reduce duplication of drug inspections and allow regulators to devote more resources to other manufacturing facilities in countries where there may be greater risk.

The FDA believes that, ultimately, the prioritization of such inspections will help identify potential drug quality problems more quickly and prevent poor quality drugs from entering the US market.

“At a time in which medical product manufacturing is truly a global enterprise, there is much to be gained by partnering with regulatory counterparts to reduce duplicative efforts and maximize global resources while realizing the greatest bang for our collective inspectional buck,” said FDA Commissioner Scott Gottlieb, MD.

“By partnering with these countries, we can create greater efficiencies and better fulfill our public health goals, relying on the expertise of our colleagues and refocusing our resources on inspections in higher-risk countries.”
