CHMP recommends inotuzumab ozogamicin for adult ALL
The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion of inotuzumab ozogamicin (Besponsa®).
The CHMP is recommending approval of inotuzumab ozogamicin for the treatment of adults with relapsed or refractory CD22-positive B-cell precursor acute lymphoblastic leukemia (ALL), including patients with Philadelphia chromosome-positive ALL who have failed treatment with at least one tyrosine kinase inhibitor.
The CHMP’s opinion will be reviewed by the European Commission, which is expected to issue a decision on approval within 67 days from adoption of the opinion.
Inotuzumab ozogamicin is an antibody-drug conjugate that consists of a monoclonal antibody targeting CD22 and a cytotoxic agent known as calicheamicin.
The product originates from a collaboration between Pfizer and Celltech (now UCB), but Pfizer has sole responsibility for all manufacturing and clinical development activities.
The application for inotuzumab ozogamicin is supported by results from a phase 3 trial, which were published in NEJM in June 2016.
The trial enrolled 326 adult patients with relapsed or refractory B-cell ALL and compared inotuzumab ozogamicin to standard of care chemotherapy.
The rate of complete remission, including incomplete hematologic recovery, was 80.7% in the inotuzumab ozogamicin arm and 29.4% in the chemotherapy arm (P<0.001). The median duration of remission was 4.6 months and 3.1 months, respectively (P=0.03).
Forty-one percent of patients treated with inotuzumab ozogamicin and 11% of those who received chemotherapy proceeded to stem cell transplant directly after treatment (P<0.001).
The median progression-free survival was 5.0 months in the inotuzumab ozogamicin arm and 1.8 months in the chemotherapy arm (P<0.001).
The median overall survival was 7.7 months and 6.7 months, respectively (P=0.04). This did not meet the prespecified boundary of significance (P=0.0208).
Liver-related adverse events were more common in the inotuzumab ozogamicin arm than the chemotherapy arm. The most frequent of these were increased aspartate aminotransferase level (20% vs 10%), hyperbilirubinemia (15% vs 10%), and increased alanine aminotransferase level (14% vs 11%).
Veno-occlusive liver disease occurred in 11% of patients in the inotuzumab ozogamicin arm and 1% in the chemotherapy arm.
There were 17 deaths during treatment in the inotuzumab ozogamicin arm and 11 in the chemotherapy arm. Four deaths were considered related to inotuzumab ozogamicin, and 2 were thought to be related to chemotherapy.

CHMP recommends approval for rituximab biosimilar
The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended marketing authorization for a biosimilar rituximab product called Rixathon.
The recommended authorization for Rixathon encompasses all the same indications as the reference medicine, MabThera, which includes non-Hodgkin lymphoma (NHL), chronic lymphocytic leukemia (CLL), rheumatoid arthritis (RA), granulomatosis with polyangiitis (GPA), and microscopic polyangiitis (MPA).
The CHMP’s recommendation for Rixathon has been forwarded to the European Commission, which normally decides whether it will grant marketing authorization for a product within 67 days from the time the CHMP adopts its opinion.
The active substance of Rixathon is rituximab, a monoclonal antibody that binds specifically to the transmembrane protein CD20, which is found on both malignant and normal B cells.
In NHL and CLL, this promotes destruction of malignant B cells and controls tumor growth. In RA, GPA, and MPA, it reduces B cells involved in their pathogenesis.
The reference product for Rixathon is Mabthera, which was authorized for use in the European Union in June 1998.
The CHMP says studies have shown Rixathon to have comparable quality, safety, and efficacy to Mabthera.1, 2, 3
The applicant for Rixathon is Sandoz GmbH.
If authorized by the European Commission, Rixathon will be available for the following indications.
NHL
Rixathon is indicated for use in combination with chemotherapy to treat previously untreated patients with stage III-IV follicular lymphoma (FL).
Rixathon maintenance therapy is indicated for the treatment of FL patients responding to induction therapy.
Rixathon monotherapy is indicated for the treatment of patients with stage III-IV FL who are chemo-resistant or are in their second or subsequent relapse after chemotherapy.
Rixathon is indicated for use in combination with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) for the treatment of patients with CD20-positive diffuse large B-cell lymphoma.
CLL
Rixathon in combination with chemotherapy is indicated for the treatment of patients with previously untreated and relapsed/refractory CLL.
The CHMP noted that limited efficacy and safety data are available for patients previously treated with monoclonal antibodies, including rituximab, or patients who are refractory to previous rituximab plus chemotherapy.
RA, GPA, and MPA
Rixathon in combination with methotrexate is indicated for the treatment of adults with severe, active RA who have had an inadequate response to or cannot tolerate other disease-modifying anti-rheumatic drugs, including one or more tumor necrosis factor inhibitor therapies.
Rixathon in combination with glucocorticoids is indicated for the induction of remission in adults with severe, active GPA or MPA.

CAR T-cell therapy receives breakthrough designation
The US Food and Drug Administration (FDA) has granted another breakthrough therapy designation to CTL019 (tisagenlecleucel-T), an investigational chimeric antigen receptor (CAR) T-cell therapy.
CTL019 now has breakthrough designation as a treatment for adults with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who have failed 2 or more prior therapies.
The FDA previously granted CTL019 breakthrough designation as a treatment for relapsed/refractory B-cell acute lymphoblastic leukemia (ALL) in pediatric and young adult patients.
Breakthrough designation is intended to expedite the development and review of new medicines that treat serious or life-threatening conditions, if those medicines have demonstrated substantial improvement over available therapies.
The breakthrough designation for CTL019 in DLBCL is based on data from the phase 2 JULIET trial (NCT02445248), in which researchers are evaluating the efficacy and safety of CTL019 in adults with relapsed/refractory DLBCL.
Findings from JULIET are expected to be presented at an upcoming medical meeting.
About CTL019
CTL019 consists of autologous T cells expressing a CD19-specific CAR. The therapy was first developed by the University of Pennsylvania.
In 2012, the university and Novartis entered into a global collaboration to further research, develop, and commercialize CAR-T cell therapies, including CTL019. Novartis holds the worldwide rights to CARs developed through the collaboration.
According to Novartis, regulatory submissions for CTL019 in the treatment of relapsed/refractory DLBCL are expected to be filed by the end of the year.
The company has already filed a biologics license application with the FDA for CTL019 as a treatment for patients with relapsed/refractory B-cell ALL. The FDA granted that application priority review.

Health Canada expands approval of daratumumab in MM
The drug is now approved for use in combination with lenalidomide and dexamethasone or bortezomib and dexamethasone to treat MM patients who have received at least 1 prior therapy.
Health Canada granted daratumumab priority review for this indication due to a high unmet medical need in patients with MM.
When a drug is granted priority review, Health Canada aims to complete its review of the drug within 180 days from the time an application is submitted.
Health Canada grants priority review to products intended for the treatment, prevention, or diagnosis of serious, life-threatening, or severely debilitating diseases or conditions.
About daratumumab
Daratumumab is a human IgG1k monoclonal antibody that binds to CD38, which is highly expressed on the surface of MM cells.
The drug is being developed by Janssen Biotech, Inc. under an exclusive worldwide license from Genmab.
Daratumumab received conditional approval in Canada last year.
In June 2016, Health Canada issued a Notice of Compliance with Conditions approving daratumumab for MM patients who had received at least 3 prior lines of therapy, including a proteasome inhibitor and an immunomodulatory agent, or patients who are refractory to both a proteasome inhibitor and an immunomodulatory agent.
Phase 3 trial data
Health Canada’s expanded approval for daratumumab is based on data from the phase 3 POLLUX and CASTOR trials.
In the POLLUX trial, researchers compared treatment with lenalidomide and dexamethasone to treatment with daratumumab, lenalidomide, and dexamethasone in patients with relapsed or refractory MM.
Patients who received daratumumab in combination had a significantly higher response rate and longer progression-free survival than patients who received the 2-drug combination.
However, treatment with daratumumab was associated with infusion-related reactions and a higher incidence of neutropenia.
Results from this trial were published in NEJM in October 2016.
In the CASTOR trial, researchers compared treatment with bortezomib and dexamethasone to treatment with daratumumab, bortezomib, and dexamethasone in patients with previously treated MM.
Patients who received the 3-drug combination had a higher response rate, longer progression-free survival, and a higher incidence of grade 3/4 adverse events than those who received the 2-drug combination.
Results from this trial were published in NEJM in August 2016.

FDA: REMS for ESAs no longer needed, though risks persist
The US Food and Drug Administration (FDA) has determined that the risk evaluation and mitigation strategy (REMS) for erythropoiesis-stimulating agents (ESAs) is no longer necessary.
The REMS was limited to the use of epoetin alfa (marketed as Epogen and Procrit) and darbepoetin alfa (marketed as Aranesp) to treat patients with anemia due to myelosuppressive chemotherapy.
The FDA said the REMS is no longer necessary to ensure that the benefits of Epogen/Procrit and Aranesp outweigh the risks these drugs pose, which include shortened overall survival and an increased risk of tumor progression or recurrence in patients with cancer.
The FDA has released the REMS requirements for these ESAs and said the risks the drugs pose can be communicated by the current product prescribing information.
The FDA decided the REMS is no longer needed based on its own analyses and an evaluation of the REMS assessment submitted by Amgen, Inc., the company that markets Epogen/Procrit and Aranesp.
Details on the analyses and evaluation are available from the following page on the FDA website: Information on Erythropoiesis-Stimulating Agents (ESA) Epoetin alfa (marketed as Procrit, Epogen), Darbepoetin alfa (marketed as Aranesp).

The US Food and Drug Administration (FDA) has granted orphan drug designation for tasquinimod as a treatment for multiple myeloma (MM).
Tasquinimod is an immunomodulatory, anti-metastatic, and anti-angiogenic compound being developed by Active Biotech AB.
The company says tasquinimod works by inhibiting the function of S100A9, a pro-inflammatory protein that is elevated in MM and other malignancies.
S100A9 is believed to aid cancer development by recruiting and activating immune cells such as myeloid-derived suppressor cells.
Active Biotech AB says that, by targeting the S100A9 pathway, tasquinimod interferes with the accumulation and activation of myeloid-derived suppressor cells in the tumor microenvironment, which decreases immune suppression and angiogenesis.
Tasquinimod also inhibits the hypoxic response in the tumor by binding to HDAC4, according to Active Biotech AB.
The company says tasquinimod has produced “robust results” in animal models of MM, and research presented at the AACR Annual Meeting 2015 supports this statement.
Investigators found that tasquinimod reduced tumor growth and improved survival in mouse models of MM. And these effects were associated with reduced angiogenesis in the bone marrow.
Tasquinimod was previously under development as a treatment for prostate cancer, but research suggested the drug did not have a favorable risk-benefit ratio in this patient population.
About orphan designation
The FDA grants orphan designation to drugs and biologics intended to treat, diagnose, or prevent rare diseases/disorders affecting fewer than 200,000 people in the US.
Orphan designation provides companies with certain incentives to develop products for rare diseases. This includes a 50% tax break on research and development, a fee waiver, access to federal grants, and 7 years of market exclusivity if the product is approved.

Topical HDAC inhibitor shows activity in MF
Results of a phase 2 trial suggest a topical, skin-directed histone deacetylase (HDAC) inhibitor can elicit responses in patients with early stage mycosis fungoides (MF).
The drug, remetinostat, was designed to be active in the skin but rapidly broken down and inactivated in blood in order to limit the adverse effects associated with systemic exposure to HDAC inhibitors.
The trial included 60 MF patients who were randomized to receive 0.5% remetinostat gel twice daily, 1% remetinostat gel once daily, or 1% remetinostat gel twice daily for between 6 and 12 months.
Results from this trial were recently released by Medivir AB, the company developing remetinostat.
The primary endpoint of the study was the proportion of patients with either a complete or partial confirmed response to therapy, assessed using the Composite Assessment of Index Lesion Severity.
Based on an intent-to-treat analysis, patients receiving the 1% remetinostat gel twice daily arm had the highest proportion of confirmed responses. Eight of 20 patients (40%) responded, which included 1 complete response.
Five of 20 patients (25%) receiving 0.5% remetinostat gel twice daily responded, as did 4 of 20 (20%) patients receiving 1% remetinostat gel once daily. None of these responses were complete responses.
Remetinostat was well-tolerated across all the dose groups, according to Medivir. There were no signs of systemic adverse effects, including those associated with systemic HDAC inhibitors.
Based on these data, Medivir expects to initiate discussions with regulatory authorities with the aim of initiating a phase 3 study later this year, and to present full phase 2 trial data at scientific meetings in the second half of 2017.
“Remetinostat was designed to effectively inhibit HDACs within cutaneous lesions but to be rapidly broken down in the bloodstream, preventing the side effects associated with systemically administered HDAC inhibitors,” said Richard Bethell, Medivir’s chief scientific officer.
“Based on the efficacy and safety data from this phase 2 study, we believe that remetinostat is capable of meeting a very important unmet need in patients with this chronic and poorly treated orphan disease.”

FDA approves drugs more quickly than EMA
The US Food and Drug Administration (FDA) reviews and approves new medicines in a shorter timeframe than the European Medicines Agency (EMA), according to an analysis published in NEJM.
The FDA has faced pressure from the public, politicians, and industry to accelerate review and approval of new medicines.
The FDA’s review process is currently being considered and reexamined as part of negotiations to reauthorize the law that directs funds to the agency—the Prescription Drug User Fee Act—which is due for reauthorization by October 2017.
To inform this debate, a group of researchers compared review times for new drugs approved by the FDA and the EMA between 2011 and 2015.
The results showed that the FDA approved more new drugs than the EMA—170 versus 144—during this time period.
The median review time was 306 days for FDA-approved drugs and 383 days for EMA-approved drugs (P<0.001).
Over the study period, the FDA approved 53 drugs intended to treat cancer/hematologic diseases, and the EMA approved 50. The median review times were 206 days and 379 days, respectively (P<0.001).
The FDA approved 74 orphan drugs, and the EMA approved 36. The median review times were 294 days and 403 days, respectively (P<0.001).
The current analysis is an update to a prior analysis, published in 2012, which showed the FDA approved new medicines more quickly than the EMA and Health Canada.
“The gap we had identified, where the FDA was 2 to 3 months faster, now it’s about 3 to 4 months faster,” said Joseph Ross, MD, of the Yale School of Medicine in New Haven, Connecticut, an author of both studies.
“This is more information that should inform upcoming debates. The FDA is already making decisions quickly, and increasing its regulatory speed shouldn’t be our number-one priority.”

Drug granted fast track designation for PNH
The US Food and Drug Administration (FDA) has granted fast track designation to Coversin™ for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) in patients who have polymorphisms conferring eculizumab resistance.
Coversin is a recombinant small protein (16,740 Da) derived from a native protein found in the saliva of the Ornithodoros moubata tick.
The drug is a second-generation complement inhibitor that acts on complement component C5, preventing release of C5a and formation of C5b-9, and also independently inhibits LTB4 activity.
Coversin is being developed by Akari Therapeutics.
Akari is evaluating Coversin in a pair of phase 2 trials.
In the first trial, researchers are evaluating Coversin in patients with PNH who have never received a complement-blocking therapy. Interim results from this ongoing trial are scheduled to be presented at Akari’s Research and Development Day on April 24 in New York, New York.
In the second phase 2 trial, researchers are evaluating Coversin in patients with PNH who have C5 polymorphisms that confer resistance to eculizumab.
One patient has been enrolled in this trial and has received Coversin for over a year. The treatment has resulted in significant lactate dehydrogenase reduction and complete complement blockade.
About fast track designation
The FDA created the fast track program to facilitate the development and expedite the review of drugs that show promise for treating serious or life-threatening diseases and address unmet medical needs.
Companies developing drugs that receive fast track designation benefit from more frequent communications and meetings with the FDA to review their drug’s development plan, including the design of proposed clinical trials, use of biomarkers, and the extent of data needed for approval.
Drugs with fast track designation may qualify for priority review as well, if relevant criteria are met. Priority review shortens the FDA review process from 10 months to 6 months.
Fast track designation also allows for a rolling review process, whereby completed sections of the investigational new drug application can be submitted for FDA review as they become available, instead of waiting for all sections to be completed.

FDA grants priority review to sBLA for blinatumomab
The US Food and Drug Administration (FDA) has accepted for priority review the supplemental biologics license application (sBLA) for blinatumomab (Blincyto®).
The aim of this application is to expand the indication for blinatumomab to include all patients with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (BCP-ALL) and to convert blinatumomab’s current accelerated approval to a full approval.
The FDA grants priority review to applications for products that may provide significant improvements in the treatment, diagnosis, or prevention of serious conditions.
The agency’s goal is to take action on a priority review application within 6 months of receiving it, rather than the standard 10 months.
The Prescription Drug User Fee Act target action date for the blinatumomab sBLA is August 14, 2017.
About blinatumomab
Blinatumomab is a bispecific, CD19-directed, CD3 T-cell engager (BiTE®) antibody construct that binds specifically to CD19 expressed on the surface of cells of B-lineage origin and CD3 expressed on the surface of T cells.
Blinatumomab currently has accelerated approval in the US as a treatment for adult and pediatric patients with Philadelphia chromosome-negative (Ph-) relapsed or refractory BCP-ALL.
The FDA-approved prescribing information for blinatumomab includes a boxed warning detailing the risk of cytokine release syndrome and neurologic toxicities.
Blinatumomab is also under a Risk Evaluation and Mitigation Strategy program in the US intended to inform healthcare providers about these risks.
Blinatumomab is being developed and marketed by Amgen.
About the sBLA
With this sBLA, Amgen is seeking to make blinatumomab available as a treatment for patients with Philadelphia chromosome-positive (Ph+) relapsed/refractory BCP-ALL (as well as Ph-).
To this end, the application includes data from the ALCANTARA study, which were just published in the Journal of Clinical Oncology.
In this trial, researchers evaluated blinatumomab in adults with Ph+ relapsed/refractory BCP-ALL who had failed treatment with at least 1 tyrosine kinase inhibitor.
Thirty-six percent of patients achieved a complete response or complete response with partial hematologic recovery within the first 2 cycles of blinatumomab treatment. Of these patients, 88% were minimal residual disease negative.
The most frequent adverse events (AEs) in this trial were pyrexia (58%), neurologic events (47%), febrile neutropenia (40%), and headache (31%). Three patients had grade 1/2 cytokine release syndrome, and 3 patients had grade 3 neurologic AEs.
The sBLA also includes overall survival (OS) data from the phase 3 TOWER trial, which is intended to support the conversion of blinatumomab’s accelerated approval to a full approval.
Results from the TOWER trial were recently published in NEJM.
In this study, researchers compared blinatumomab to standard of care (SOC) chemotherapy (4 different regimens) in adults with Ph- relapsed/refractory BCP-ALL.
Blinatumomab produced higher response rates and nearly doubled OS compared to SOC. The median OS was 7.7 months in the blinatumomab arm and 4 months in the SOC arm. The hazard ratio for death was 0.71 (P=0.012).
The incidence of grade 3 or higher AEs was higher in the SOC arm, but the incidence of serious AEs was higher in the blinatumomab arm.
