The US Food and Drug Administration (FDA) has granted breakthrough designation for the chimeric antigen receptor (CAR) T-cell therapy KTE-C19 as a treatment for refractory diffuse large B-cell lymphoma (DLBCL), primary mediastinal B-cell lymphoma (PMBCL), and transformed follicular lymphoma (TFL).

To create KTE-C19, T cells are modified to express a CAR designed to target CD19, a cell-surface protein expressed in B-cell lymphomas and leukemias.

Breakthrough therapy designation is designed to accelerate the development and review of medicines that demonstrate early clinical evidence of a substantial improvement over current treatment options for serious diseases.

The designation conveys all the features of the FDA’s fast track program, as well as more intensive FDA guidance on an efficient drug development program and eligibility for rolling review and priority review.

KTE-C19 research

In a study published in the Journal of Clinical Oncology last year, researchers evaluated KTE-C19 in 15 patients with advanced B-cell malignancies.

The patients received a conditioning regimen of cyclophosphamide and fludarabine, followed 1 day later by a single infusion of KTE-C19. The researchers noted that the conditioning regimen is known to be active against B-cell malignancies and could have made a direct contribution to patient responses.

Thirteen patients were evaluable for response. One patient was lost to follow-up because of noncompliance, and 1 died soon after treatment. The researchers said the cause of death was likely cardiac arrhythmia.

The overall response rate was 92%. Eight patients achieved a complete response (CR), and 4 had a partial response (PR).

Of the 7 patients with DLBCL, 4 achieved a CR, 2 achieved a PR, and 1 had stable disease. Three of the CRs were ongoing at the time of publication, with the duration ranging from 9 months to 22 months.

Of the 4 patients with chronic lymphocytic leukemia, 3 had a CR, and 1 had a PR. All 3 CRs were ongoing at the time of publication, with the duration ranging from 14 months to 23 months.

Among the 2 patients with indolent lymphomas, 1 achieved a CR, and 1 had a PR. The duration of the CR was 11 months at the time of publication.

KTE-C19 elicited a number of adverse events, including fever, hypotension, delirium, and other neurologic toxicities. All but 2 patients experienced grade 3/4 adverse events.

Three patients developed unexpected neurologic abnormalities. One patient experienced aphasia and right-sided facial paresis. One patient developed aphasia, confusion, and severe, generalized myoclonus. And 1 patient had aphasia, confusion, hemifacial spasms, apraxia, and gait disturbances.

KTE-C19 is currently under investigation in a phase 2 trial of refractory DLBCL, PMBCL, and TFL (ZUMA-1), a phase 2 trial of relapsed/refractory mantle cell lymphoma (ZUMA-2), a phase 1/2 trial of relapsed/refractory adult acute lymphoblastic leukemia (ZUMA-3), and a phase 1/2 trial of relapsed/refractory pediatric acute lymphoblastic leukemia (ZUMA-4).

Data from ZUMA-1 were presented at the 2015 ASH Annual Meeting (abstracts 2730 and 3991).

KTE-C19 is under development by Kite Pharma.

Warfarin tablets

A retrospective study published in The BMJ suggests the possibility of a significant drug interaction between warfarin and the sulfonylureas glipizide and glimepiride.

Taking either of these diabetes drugs in conjunction with warfarin was linked to increased hospitalizations for falls, altered mental state, and insulin shock among patients 65 and older.

Hospital admissions or emergency room visits were nearly 22% higher for patients who were taking warfarin with glipizide or glimepiride, compared to patients taking the diabetes drugs alone.

Clinical references warn doctors of a potential interaction between these drugs, but evidence of it has been thin, according to lead study author John Romley, PhD, of the University of Southern California (USC) in Los Angeles.

He and his colleagues said that, in their study, evidence of the drug-to-drug interaction was clear.

When taken with glipizide or glimepiride, warfarin can intensify their effects and send blood sugar levels crashing. Patients experiencing hypoglycemia may seem drunk, lightheaded, and confused, and are at risk of falling.

“The take-home message is simply that an interaction can occur that has clinical significance, so providers need to be aware in order to prevent a low blood sugar issue from occurring,” said Anne Peters, MD, also of USC.

“Sometimes this means having the patient monitor their blood sugar levels more often. There are many ways to deal with the issue if one is forewarned.”

Pharmacists don’t need to change patient instructions, added Bradley Williams, PharmD, of USC.

“What it does require is for pharmacists and other clinicians to be more vigilant when a sulfonylurea is added to a regimen that includes warfarin, as well as when a patient who is taking both has a change in their medical status,” Dr Williams said.

“I think additional research into the potential interactions between medications for diabetes and warfarin, as well as other drugs that affect blood clotting, is warranted because of the potential consequences of excessive bleeding.”

For the current study, the researchers analyzed a random sample of 465,918 Medicare beneficiaries with diabetes who filled a prescription for glipizide or glimepiride between 2006 and 2011. About 15% of these patients (n=71,895) also filled a prescription for warfarin.

The researchers found that hospital admissions or emergency department visits for hypoglycemia were more common with concurrent warfarin and glipizide/glimepiride use than with glipizide/glimepiride use alone. The adjusted odds ratio (AOR) was 1.22.

The risk of hypoglycemia associated with concurrent use was higher among patients taking warfarin for the first time, as well as in patients ages 65 to 74.

Concurrent use of warfarin and glipizide/glimepiride was also associated with hospital admission or emergency department visits for fall-related fractures (AOR=1.47) and altered consciousness/mental status (AOR=1.22).

The researchers said these findings may not be generalizable beyond the elderly Medicare population.

They also noted that their findings could be confounded by some unmeasured characteristics in patients that may be connected to warfarin use or a risk for hypoglycemia. Another limitation of this study is that the researchers did not measure drug use directly.

The US Food and Drug Administration (FDA) has approved a recombinant von Willebrand factor product, Vonvendi (formerly BAX 111), for use in adults with von Willebrand disease (VWD).

Vonvendi is the first FDA-approved recombinant von Willebrand factor.

It is now approved for the on-demand treatment and control of bleeding episodes in VWD patients 18 years of age and older.

Vonvendi is expected to be broadly available in the US in late 2016.

Compared to other marketed von Willebrand factor concentrates, Vonvendi contains a more consistent concentration of ultra-large-molecular-weight multimers. And the product is developed using a plasma- and albumin-free manufacturing method.

Vonvendi is the first von Willebrand factor concentrate in the US that contains only trace amounts of factor VIII (FVIII), offering the flexibility to administer FVIII only when needed.

The FDA’s approval of Vonvendi was based on results from a phase 3 trial recently published in Blood. The study included 49 patients with WWD who received Vonvendi with and without recombinant FVIII.

All participants reported successful treatment of bleeding episodes. Most (96.9%) treated bleeds (n=192 bleeds in 22 patients) achieved an “excellent” efficacy rating.

Most bleeds (81.8%) were resolved with a single infusion of Vonvendi, and the treatment had a mean half-life of 21.9 hours.

There were 8 adverse events considered related to Vonvendi, but only 2 of these were serious. One patient experienced 2 simultaneous serious adverse events—chest discomfort and increased heart rate—but these were resolved.

There were no thrombotic events in this trial, no treatment-related binding or neutralizing antibodies against von Willebrand factor, and no neutralizing antibodies against FVIII.

Vonvendi is manufactured by Baxalta Incorporated. Baxalta said it is building a robust clinical development program to optimize patient access to Vonvendi worldwide. A series of clinical programs are planned to evaluate its use for prophylaxis, surgical, and pediatric indications.

Baxalta expects to file for regulatory approvals in Europe in 2017 and in other markets around the world.

For more details on Vonvendi, see the product information.

The price of cancer drugs varies widely between European countries, Australia, and New Zealand, according to a study published in The Lancet Oncology.

The study indicates that, overall, the UK and Mediterranean countries such as Greece, Spain, and Portugal pay the lowest average unit manufacturer prices for a group of 31 originator cancer drugs (new drugs under patent).

And Sweden, Switzerland, and Germany pay the highest prices.

The greatest differences in price were noted for gemcitabine, which costs €209 per vial in New Zealand and €43 in Australia, and zoledronic acid, which costs €330 per vial in New Zealand but €128 in Greece.*

“Public payers in Germany are paying 223% more in terms of official prices for interferon alfa 2b for melanoma and leukemia treatment than those in Greece,” noted study author Sabine Vogler, PhD, of the WHO Collaborating Centre for Pharmaceutical Pricing and Reimbursement Policies in Vienna, Austria.

“For gefitinib to treat non-small-lung cancer, the price in Germany is 172% higher than in New Zealand.”

To uncover these price differences, Dr Vogler and her colleagues reviewed official drug price data from the Pharma Price Information (PPI) service of the Austrian Public Health Institute for 16 European countries**, and from the pharmaceutical schedules in Australia and New Zealand.

The researchers compared what manufacturers charged for a unit (ie, price per tablet or vial) of 31 originator cancer drugs in June 2013.

None of these drugs had a unit price lower than €10. Four drugs (13%) had an average unit manufacturer price between €250 and €500, and 2 drugs (6%) had an average unit price between €500 and €1000.

Seven drugs (23%) had an average unit price higher than €1000. For example, plerixafor cost over €5000 per injection.

The price differences between the highest- and lowest-priced countries ranged from 28% to 50% for a third of the drugs sampled, between 50% and 100% for half of the drugs, and between 100% and 200% for 3 drugs (10%).

The researchers noted that information on real drug prices is scarce. The cancer drug prices they surveyed did not include confidential discounts such as those agreed upon in managed-entry arrangements that are increasingly used in countries such as Australia, Italy, the UK, and the Netherlands.

“Some high-income countries have managed to barter the manufacturers down to lower prices, but these agreements, including the agreed prices, are confidential,” Dr Vogler explained.

“Although these agreements ensure patient access to new drugs, other countries risk overpaying when setting drug prices through the common practice of external price referencing, or international price comparison, because they can only use the official undiscounted prices as a benchmark. There needs to be far more transparency.”

“We hope that our findings will provide concrete evidence for policymakers to take action to address high prices and ensure more transparency in cancer drug pricing so that costs and access to new drugs does not depend on where a patient lives.”

*Gemcitabine and zoledronic acid have generic versions in several countries, and originator prices were decreased in some countries following patent expiry but not in others.

None of these drugs had a unit price lower than €10. Four drugs (13%) had an average unit manufacturer price between €250 and €500, and 2 drugs (6%) had an average unit price between €500 and €1000.

Seven drugs (23%) had an average unit price higher than €1000. For example, plerixafor cost over €5000 per injection.

The price differences between the highest- and lowest-priced countries ranged from 28% to 50% for a third of the drugs sampled, between 50% and 100% for half of the drugs, and between 100% and 200% for 3 drugs (10%).

The researchers noted that information on real drug prices is scarce. The cancer drug prices they surveyed did not include confidential discounts such as those agreed upon in managed-entry arrangements that are increasingly used in countries such as Australia, Italy, the UK, and the Netherlands.

“Some high-income countries have managed to barter the manufacturers down to lower prices, but these agreements, including the agreed prices, are confidential,” Dr Vogler explained.

“Although these agreements ensure patient access to new drugs, other countries risk overpaying when setting drug prices through the common practice of external price referencing, or international price comparison, because they can only use the official undiscounted prices as a benchmark. There needs to be far more transparency.”

“We hope that our findings will provide concrete evidence for policymakers to take action to address high prices and ensure more transparency in cancer drug pricing so that costs and access to new drugs does not depend on where a patient lives.”

*Gemcitabine and zoledronic acid have generic versions in several countries, and originator prices were decreased in some countries following patent expiry but not in others.

The price of cancer drugs varies widely between European countries, Australia, and New Zealand, according to a study published in The Lancet Oncology.

The study indicates that, overall, the UK and Mediterranean countries such as Greece, Spain, and Portugal pay the lowest average unit manufacturer prices for a group of 31 originator cancer drugs (new drugs under patent).

And Sweden, Switzerland, and Germany pay the highest prices.

The greatest differences in price were noted for gemcitabine, which costs €209 per vial in New Zealand and €43 in Australia, and zoledronic acid, which costs €330 per vial in New Zealand but €128 in Greece.*

“Public payers in Germany are paying 223% more in terms of official prices for interferon alfa 2b for melanoma and leukemia treatment than those in Greece,” noted study author Sabine Vogler, PhD, of the WHO Collaborating Centre for Pharmaceutical Pricing and Reimbursement Policies in Vienna, Austria.

“For gefitinib to treat non-small-lung cancer, the price in Germany is 172% higher than in New Zealand.”

Bristol-Myers Squibb

The US Food and Drug Administration (FDA) has approved elotuzumab (Empliciti) for use in combination with lenalidomide and dexamethasone to treat multiple myeloma (MM) patients who have received 1 to 3 prior therapies.

Elotuzumab is an immunostimulatory antibody that specifically targets signaling lymphocyte activation molecule family member 7 (SLAMF7), a cell-surface glycoprotein that is expressed on myeloma cells independent of cytogenetic abnormalities.

Elotuzumab is the first immunostimulatory antibody approved for MM.

Bristol-Myers Squibb said it expects to begin shipping elotuzumab this week. The drug will be available for injection for intravenous use in 300 mg and 400 mg vials.

Elotuzumab is currently under review by the European Medicines Agency and has been granted accelerated assessment.

The FDA previously granted elotuzumab breakthrough therapy designation, orphan drug designation, and priority review.

Bristol-Myers Squibb and AbbVie are co-developing elotuzumab, with Bristol-Myers Squibb solely responsible for commercial activities. For more details on the drug, see the full prescribing information.

ELOQUENT-2 trial

The FDA’s approval of elotuzumab is primarily based on data from the phase 3 ELOQUENT-2 trial, which were presented at ASCO 2015 and published in NEJM.

The trial included 646 MM patients who had received 1 to 3 prior therapies. Baseline patient demographics and disease characteristics were well balanced between treatment arms.

Patients were randomized 1:1 to receive either elotuzumab at 10 mg/kg in combination with lenalidomide and dexamethasone (len-dex) or len-dex alone in 4-week cycles until disease progression or unacceptable toxicity.

The minimum follow-up for all study subjects was 24 months. The co-primary endpoints were progression-free survival (PFS) and overall response rate.

The overall response rate was 78.5% in the elotuzumab arm and 65.5% in the len-dex arm (P=0.0002).

The median PFS was 19.4 months in the elotuzumab arm and 14.9 months in the len-dex arm (P=0.0004). At 1 year, the PFS was 68% in the elotuzumab arm and 57% in the len-dex arm. At 2 years, the PFS was 41% and 27%, respectively.

Serious adverse events occurred in 65.4% of patients in the elotuzumab arm and 56.5% in the len-dex arm. The most frequent serious adverse events in each arm, respectively, were pneumonia (15.4% vs 11%), pyrexia (6.9% vs 4.7%), respiratory tract infection (3.1% vs 1.3%), anemia (2.8% vs 1.9%), pulmonary embolism (3.1% vs 2.5%), and acute renal failure (2.5% vs 1.9%).

The most common adverse events in the elotuzumab arm and len-dex arm, respectively, were fatigue (61.6% vs 51.7%), diarrhea (46.9% vs 36.0%), pyrexia (37.4% vs 24.6%), constipation (35.5% vs 27.1%), cough (34.3% vs 18.9%), peripheral neuropathy (26.7% vs 20.8%), nasopharyngitis (24.5% vs 19.2%), upper respiratory tract infection (22.6% vs 17.4%), decreased appetite (20.8% vs 12.6%), and pneumonia (20.1% vs 14.2%).

The European Commission (EC) has granted marketing authorization for idarucizumab (Praxbind), a humanized antibody fragment designed to reverse the anticoagulant effects of dabigatran etexilate (Pradaxa) in cases of emergency surgery/urgent procedures or in situations of life-threatening or uncontrolled bleeding.

The EC’s decision applies to the 28 countries of the European Union (EU) as well as Iceland, Lichtenstein, and Norway.

Idarucizumab is the first specific reversal agent for a non-vitamin K antagonist oral anticoagulant to be approved for use in the EU. The drug was approved in the US last month.

The EC’s decision to approve idarucizumab was based on results in healthy volunteers and an interim analysis of the phase 3 RE-VERSE AD trial.

In the study of healthy volunteers, the pharmacokinetic profile of idarucizumab met the requirement for rapid peak exposure and rapid elimination, with no effect on pharmacodynamic parameters. And researchers said the drug was well-tolerated.

In RE-VERSE AD, researchers evaluated idarucizumab in emergency settings. The drug normalized diluted thrombin time and ecarin clotting time in a majority of dabigatran-treated patients with uncontrolled or life-threatening bleeding complications and most patients who required emergency surgery or an invasive procedure.

The researchers said there were no safety concerns related to idarucizumab. However, 23% of patients in this trial experienced serious adverse events, 20% of patients died, and several patients had thrombotic or bleeding events.

Boehringer Ingelheim, the company developing idarucizumab, said it is committed to making the drug available as widely as possible and will launch idarucizumab in European countries as soon as national requirements allow.

Boehringer Ingelheim is also the maker of dabigatran, which is currently approved in the EU for the following indications:

• Prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation and a risk factor for stroke
• Primary prevention of venous thromboembolic events in patients undergoing elective total hip replacement surgery or total knee replacement surgery
• Treatment of deep vein thrombosis and pulmonary embolism and the prevention of recurrent deep vein thrombosis and pulmonary embolism in adults.

The European Commission (EC) has granted conditional marketing authorization for blinatumomab (Blincyto) to treat adults with Philadelphia chromosome-negative (Ph-) relapsed or refractory B-precursor acute lymphoblastic leukemia (ALL).

This applies to the 28 member countries of the European Union as well as Iceland, Lichtenstein, and Norway.

Conditional marketing authorizations are valid for 1 year, on a renewable basis. The holder is required to complete ongoing studies or conduct new studies with the goal of confirming that a drug’s benefit-risk balance is positive.

Conditional marketing authorization is converted to a full authorization once these commitments have been fulfilled.

The EC granted conditional marketing authorization for blinatumomab based on a pair of phase 2 trials—Study ‘211 and Study ‘206.

Study ‘211

Results of Study ‘211 were presented at EHA 2014. The trial included 189 patients with Ph- relapsed or refractory B-precursor ALL.

The primary endpoint was complete remission or complete remission with partial hematologic recovery (CR/CRh). About 43% of patients achieved this endpoint within 2 cycles of therapy.

According to researchers, the most serious adverse events in this study were infection (31.7%), neurologic events (16.4%), neutropenia/febrile neutropenia (15.3%), cytokine release syndrome (CRS, 0.5%), and tumor lysis syndrome (0.5%).

Study ‘206

Results of Study ‘206 were presented at ASCO 2012. The trial included 36 patients with relapsed or refractory B-precursor ALL.

In this trial, the CR/CRh rate was 69.4% (25/36), with 15 patients achieving a CR (41.7%), and 10 patients achieving CRh (27.8%).

The “medically important” adverse events in this study, according to researchers, were CRS (n=3), central nervous system (CNS) events (3 seizures and 3 cases of encephalopathy), and fungal infection resulting in death (n=1).

However, the researchers found they could prevent CRS with dexamethasone. In addition, the CNS events were reversible, and blinatumomab could be reintroduced in 4 of the 6 patients with CNS events.

About blinatumomab

Blinatumomab is a bispecific T-cell engager (BiTE®) antibody construct that binds to CD19 on the surface of B cells and CD3 on the surface of T cells.

BiTE antibody constructs are intended to help the immune system detect and target malignant cells. The modified antibodies are designed to engage 2 different targets simultaneously, thereby juxtaposing T cells to cancer cells.

BiTE antibody constructs help place the T cells within reach of the targeted cells, with the intent of allowing T cells to inject toxins and trigger apoptosis in the cancer cells.

Blinatumomab was granted orphan drug designation by the European Medicines Agency in 2009 for the treatment of ALL.

The drug was granted breakthrough therapy designation and priority review by the US Food and Drug Administration.

Blinatumomab has conditional approval in the US to treat patients with relapsed or refractory Ph- B-precursor ALL. Continued approval for this indication may be contingent upon verification of clinical benefit in subsequent trials.

Blinatumomab is being developed by Amgen.

Blinatumomab is a bispecific T-cell engager (BiTE®) antibody construct that binds to CD19 on the surface of B cells and CD3 on the surface of T cells.

BiTE antibody constructs are intended to help the immune system detect and target malignant cells. The modified antibodies are designed to engage 2 different targets simultaneously, thereby juxtaposing T cells to cancer cells.

BiTE antibody constructs help place the T cells within reach of the targeted cells, with the intent of allowing T cells to inject toxins and trigger apoptosis in the cancer cells.

Blinatumomab was granted orphan drug designation by the European Medicines Agency in 2009 for the treatment of ALL.

The drug was granted breakthrough therapy designation and priority review by the US Food and Drug Administration.

Blinatumomab has conditional approval in the US to treat patients with relapsed or refractory Ph- B-precursor ALL. Continued approval for this indication may be contingent upon verification of clinical benefit in subsequent trials.

Blinatumomab is being developed by Amgen.

The European Commission (EC) has granted conditional marketing authorization for blinatumomab (Blincyto) to treat adults with Philadelphia chromosome-negative (Ph-) relapsed or refractory B-precursor acute lymphoblastic leukemia (ALL).

This applies to the 28 member countries of the European Union as well as Iceland, Lichtenstein, and Norway.

Conditional marketing authorizations are valid for 1 year, on a renewable basis. The holder is required to complete ongoing studies or conduct new studies with the goal of confirming that a drug’s benefit-risk balance is positive.

Conditional marketing authorization is converted to a full authorization once these commitments have been fulfilled.

The EC granted conditional marketing authorization for blinatumomab based on a pair of phase 2 trials—Study ‘211 and Study ‘206.

Study ‘211

Results of Study ‘211 were presented at EHA 2014. The trial included 189 patients with Ph- relapsed or refractory B-precursor ALL.

The primary endpoint was complete remission or complete remission with partial hematologic recovery (CR/CRh). About 43% of patients achieved this endpoint within 2 cycles of therapy.

According to researchers, the most serious adverse events in this study were infection (31.7%), neurologic events (16.4%), neutropenia/febrile neutropenia (15.3%), cytokine release syndrome (CRS, 0.5%), and tumor lysis syndrome (0.5%).

Study ‘206

Results of Study ‘206 were presented at ASCO 2012. The trial included 36 patients with relapsed or refractory B-precursor ALL.

In this trial, the CR/CRh rate was 69.4% (25/36), with 15 patients achieving a CR (41.7%), and 10 patients achieving CRh (27.8%).

The “medically important” adverse events in this study, according to researchers, were CRS (n=3), central nervous system (CNS) events (3 seizures and 3 cases of encephalopathy), and fungal infection resulting in death (n=1).

However, the researchers found they could prevent CRS with dexamethasone. In addition, the CNS events were reversible, and blinatumomab could be reintroduced in 4 of the 6 patients with CNS events.

Antihemophilic factor

The European Commission (EC) has approved the recombinant factor VIII Fc fusion protein efmoroctocog alfa (Elocta) to treat patients with hemophilia A in the European Union (EU) as well as Iceland, Liechtenstein, and Norway.

Efmoroctocog alfa is indicated for both on-demand and prophylactic treatment of hemophilia A in patients of all ages.

Research has shown that efmoroctocog alfa has an extended half-life compared to recombinant factor VIII.

Efmoroctocog alfa will be the first hemophilia A treatment in the EU to offer prolonged protection against bleeding episodes with prophylactic injections every 3 to 5 days.

The product is expected to launch in initial EU countries in early 2016.

The EC’s approval of efmoroctocog alfa was based on data from 2 phase 3 studies: A-LONG and Kids A-LONG.

A-LONG

The A-LONG study included 165 previously treated males 12 years of age and older with severe hemophilia A. Researchers evaluated individualized and weekly prophylaxis to reduce or prevent bleeding episodes and on-demand dosing to treat bleeding episodes.

Prophylaxis with efmoroctocog alfa resulted in low annualized bleeding rates, and a majority of bleeding episodes were controlled with a single injection of efmoroctocog alfa.

None of the patients developed neutralizing antibodies, efmoroctocog alfa was considered well-tolerated, and the product had a prolonged half-life when compared with recombinant factor VIII.

Kids A-LONG

The Kids A-LONG study included 71 boys (younger than 12) with severe hemophilia A who had at least 50 prior exposure days to factor VIII therapies.

The children saw their median annualized bleeding rate decrease with efmoroctocog alfa, and close to half of the children did not have any bleeding episodes while they were receiving efmoroctocog alfa.

None of the patients developed inhibitors, and researchers said adverse events were typical of a pediatric hemophilia population.

ASPIRE

Participants in both the A-LONG and Kids A-LONG trials were able to enroll in ASPIRE, a phase 3 extension study evaluating the long-term safety and efficacy of efmoroctocog alfa.

Interim results of ASPIRE suggested that extended treatment with efmoroctocog alfa was largely safe and effective.

About efmoroctocog alfa

Efmoroctocog alfa was developed by fusing B-domain deleted factor VIII to the Fc portion of immunoglobulin G subclass 1. It is believed that this enables efmoroctocog alfa to utilize a naturally occurring pathway to prolong the time the therapy remains in the body.

Sobi and Biogen are collaborators in the development and commercialization of efmoroctocog alfa for hemophilia A.

Last year, Sobi exercised its opt-in right to assumeefmoroctocog alfa’s final development and commercialization in pre-specified territories, which includes Europe, North Africa, Russia, and certain countries in the Middle East.

Biogen leads development and manufacturing of the product and holds commercialization rights in North America and all other regions in the world outside of the Sobi territories.

Elocta is the trade name for efmoroctocog alfa in Sobi’s territory. The product is approved under the name Eloctate (Antihemophilic Factor [Recombinant], Fc Fusion Protein) in the US, Canada, Australia, New Zealand, and Japan.
