FDA rejects ready-to-use bivalirudin formulation
Image by Kevin MacKenzie
The US Food and Drug Administration (FDA) has said it cannot, at present, approve a ready-to-use (RTU) formulation of bivalirudin (Kangio).
The product is a liquid, intravenous formulation of 5 mg/mL of bivalirudin in a 50-mL vial.
It does not require reconstitution before administration.
This RTU bivalirudin is intended for use as an anticoagulant in patients with unstable angina who are undergoing percutaneous transluminal coronary angioplasty.
The drug is also intended for patients undergoing percutaneous coronary intervention (PCI) with provisional use of a glycoprotein IIb/IIIa inhibitor and for patients undergoing PCI who have or are at risk of developing heparin-induced thrombocytopenia and thrombosis syndrome.
The RTU bivalirudin contains the same active ingredient and is designed to be given at the same dose and rate as Angiomax, a lyophilized powder form of bivalirudin that must be reconstituted. The RTU formulation does not require any reconstitution or initial dilution, which is intended to reduce work flow and the risk of dosing errors.
The FDA issued a complete response letter to the company developing the RTU formulation of bivalirudin, Eagle Pharmaceuticals.
The FDA issues complete response letters to communicate that the initial review of an application is complete, but the agency cannot approve the application in its present form and requests additional information.
In its letter to Eagle Pharmaceuticals, the FDA requested further characterization of bivalirudin-related substances in the drug product. The company said it will work directly with the FDA to determine an appropriate path forward to address the comments.
“We are evaluating the FDA’s response and will work closely with the agency to better understand and address their comments regarding Kangio,” said Scott Tarriff, president and chief executive officer of Eagle Pharmaceuticals.
“We remain committed to Kangio as an important new formulation of bivalirudin for intravenous use, offering multiple benefits for patients and caregivers.”

FDA approves product for hemophilia A
Photo by Bill Branson
The US Food and Drug Administration (FDA) has approved the recombinant antihemophilic factor Kovaltry for the treatment of adults and children with hemophilia A.
Kovaltry is an unmodified, full-length factor VIII compound indicated for on-demand treatment and control of bleeding episodes, perioperative management of bleeding, and routine prophylaxis to reduce the frequency of bleeding episodes.
Dosing of Kovaltry should be individualized based on each patient’s clinical response.
The recommended dosing for adults and adolescents is 20 to 40 IU per kg of body weight 2 or 3 times per week. The recommended dosing for children age 12 and younger is 25 to 50 IU per kg of body weight twice weekly, 3 times weekly, or every other day, according to individual requirements.
For more details, see the full prescribing information.
The FDA’s approval of Kovaltry is based on results from the LEOPOLD trials—3 multinational trials of patients with severe hemophilia A. The trials were supported by Bayer HealthCare AG, the company developing Kovaltry.
LEOPOLD I
LEOPOLD I is an open-label, cross-over, phase 3 study of males, ages 12 to 65, with severe hemophilia A. Sixty-two patients were assigned to either 2- or 3-times-weekly dosing with Kovaltry, based on each patient’s phenotype, prior bleeding history, and other factors.
The median annualized bleeding rate (ABR) was 1.0 for all the patients who received Kovaltry prophylaxis, 1.0 for patients who received twice-weekly prophylaxis, and 2.0 for patients who received thrice-weekly prophylaxis.
LEOPOLD II
LEOPOLD II is a randomized, cross-over, open-label trial conducted in males ages 12 to 65. In this phase 3 study, 80 subjects were randomized to receive Kovaltry as a low-dose prophylaxis regimen (n=28) twice per week, high-dose prophylaxis (n=31) 3 times a week, or on-demand treatment (n=21).
The median ABR was significantly lower in patients who received either prophylactic regimen than those who received on-demand treatment—2.0 and 60.0, respectively (P<0.0001). The median ABR was 4.0 for patients who received twice-weekly prophylaxis and 2.0 for patients who received thrice-weekly prophylaxis.
LEOPOLD Kids
LEOPOLD Kids is an open-label, non-randomized, phase 3 study designed to evaluate Kovaltry in children age 12 and younger. The study is divided into 2 parts. Part A enrolled only previously treated children, and part B, which is ongoing, includes only untreated children.
For part A, 51 children received Kovaltry twice a week, 3 times a week, or every other day (according to investigator decision) for at least 50 exposure days. The median ABR within 48 hours of prophylactic injection was 0, and the median ABR independent of the time of injection was 1.9.
Safety results
For all 3 trials, 193 patients were evaluable for safety. Adverse reactions were defined as treatment-emergent adverse events with at least a reasonable suspected causal relationship to Kovaltry.
The researchers said the frequency, type, and severity of adverse reactions in children were similar to those observed in adults and adolescents.
The adverse reactions included headache (7.3%), pyrexia (4.1%), pruritus (3.1%), injection site reactions (2.6%), insomnia (2.6%), rash (2.6%), abdominal pain (2.1%), dyspepsia (2.1%), abdominal discomfort (1.6%), lymphadenopathy (1%), dizziness (1%), allergic dermatitis (1%), heart palpitations (1%), sinus tachycardia (1%), chest discomfort (1%), hypersensitivity (0.5%), dysgeusia (0.5%), urticaria (0.5%), and flushing (0.5%).
None of the patients developed factor VIII inhibitors.

FDA approves drug for 2 indications in MM

Spectrum Pharmaceuticals
The US Food and Drug Administration (FDA) has approved a new formulation of melphalan for injection (Evomela) for 2 indications.
The drug is now approved for use as a high-dose conditioning treatment prior to autologous hematopoietic stem cell transplant (HSCT) in patients with multiple myeloma (MM) and for the palliative treatment of patients with MM for whom oral therapy is not appropriate.
Evomela is the first product to be FDA-approved for the high-dose conditioning indication in MM. The FDA previously granted the drug orphan designation for this indication.
About Evomela
Evomela is a Captisol-enabled, propylene glycol-free melphalan formulation. This formulation eliminates the need to use a propylene glycol-containing custom diluent, which is required with other intravenous melphalan formulations and has been reported to cause renal and cardiac side effects.
Captisol is a chemically modified cyclodextrin with a structure designed to optimize the solubility and stability of drugs.
The use of Captisol technology to reformulate melphalan is reported to improve the drug’s stability, extending its use time. The technology allows the admixture solution to be stable for 4 hours at room temperature, in addition to the 1 hour following reconstitution, and for 24 hours at refrigerated temperature (5°C).
This is anticipated to simplify preparation and administration logistics and allow for slower infusion rates and longer administration durations for pre-transplant chemotherapy.
The full prescribing information for Evomela is available at www.evomela.com.
Spectrum Pharmaceuticals gained global development and commercialization rights to Evomela from Ligand Pharmaceuticals Incorporated in March 2013.
Spectrum assumed responsibility for completing the pivotal phase 2 trial of Evomela and was responsible for filing the new drug application. Spectrum filed the application in December 2014, and the FDA accepted it the following March.
Phase 2 study
Evomela was approved by the FDA based on its bioequivalence to the standard melphalan formulation (Alkeran) in a phase 2 study.
Initial results from this trial (phase 2a) were published in Bone Marrow Transplantation in June 2014. Phase 2b results were published in Biology of Blood and Marrow Transplantation in September 2015.
Phase 2b included 61 patients. Fifty-six had newly diagnosed MM, and 5 had relapsed MM following prior HSCT.
The patients received Evomela at 200 mg/m2, given as 2 doses on day -3 and day -2 prior to autologous HSCT (day 0).
All 61 patients achieved myeloablation at a median of 5 days post-HSCT. And all patients had successful neutrophil and platelet engraftment at a median of 12 days and 13 days post-HSCT, respectively.
Efficacy was assessed by clinical response at day 100. According to investigator assessment, the overall response rate was 95%, and the complete response (CR) rate was 31%.
According to independent pathology review, the overall response rate was 100%, and the CR rate was 21%. The lower rate of confirmed CRs in the independent review was due to missing data.
Treatment-related mortality was 0%, and non-hematologic adverse events were mostly grade 1 and 2 in severity. The incidence of grade 3 mucositis and grade 3 stomatitis were 10% and 5%, respectively, with no grade 4 mucositis or stomatitis reported.
Twenty percent of patients experienced treatment-emergent serious adverse events, most of which were grade 3 and consisted of events commonly reported in patients undergoing myeloablative chemotherapy. No new safety signals were identified.

Gilead Sciences
The US Food and Drug Administration (FDA) has reported that Gilead Sciences, Inc., is stopping 6 clinical trials of idelalisib (Zydelig) due to adverse events (AEs) observed in patients receiving idelalisib in combination with other drugs.
The AEs, which include deaths, were mostly related to infections.
The trials include patients with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma, and indolent non-Hodgkin lymphomas.
The FDA said it is reviewing the findings of these trials and will communicate new information as necessary.
A few days ago, the European Medicines Agency (EMA) announced its decision to review the safety of idelalisib due to the aforementioned AEs. The EMA said it is reviewing data from 3 idelalisib trials.
While this review is underway, the EMA advised that patients starting or already on treatment with idelalisib be carefully monitored for signs of infection. If the drug is well tolerated, treatment should not be stopped.
The FDA has not made any recommendations about treatment with idelalisib.
About idelalisib
Idelalisib is currently approved by the FDA for use in combination with rituximab to treat patients with relapsed CLL who cannot receive rituximab alone.
Idelalisib also has accelerated approval from the FDA to treat patients with relapsed follicular lymphoma who have received at least 2 prior systemic therapies and patients with relapsed small lymphocytic lymphoma who have received at least 2 prior systemic therapies.
In the European Union, idelalisib is approved for use in combination with rituximab to treat adults with CLL who have received at least 1 prior therapy or as first-line treatment in the presence of 17p deletion or TP53 mutation in CLL patients deemed unsuitable for chemo-immunotherapy.
Idelalisib is also approved in the European Union as monotherapy for adults with follicular lymphoma that is refractory to 2 prior lines of treatment.

Drug granted orphan designation for DLBCL
The US Food and Drug Administration (FDA) has granted orphan designation to the oncology drug candidate PNT2258 for the treatment of diffuse large B-cell lymphoma (DLBCL).
The FDA grants orphan designation to drugs intended to treat conditions affecting fewer than 200,000 patients in the US.
The designation provides the drug’s sponsor with various development incentives, including opportunities to apply for research-related tax credits and grant funding, assistance in designing clinical trials, and 7 years of US market exclusivity if the drug is approved.
About PNT2258
PNT2258 is designed to target cancers that overexpress BCL2, and BCL2 overexpression is thought to be a key driver of DLBCL.
PNT2258 consists of a single-stranded, 24-base DNAi oligonucleotide known as PNT100 that is encapsulated in lipid nanoparticles (LNPs).
The DNAi technology platform is based on a discovery that single-stranded DNA oligonucleotides can interact with genomic DNA to interfere with oncogenes. PNT100 DNAi is designed to target a genetic regulatory region associated with BCL2.
The LNPs are designed to provide enhanced serum stability and optimized pharmacokinetic properties to facilitate broad systemic distribution after intravenous infusion. Within the acidic environment found in tumors, the LNPs become positively charged and therefore more amenable to cellular uptake and cytoplasmic release of their payloads.
Trials of PNT2258
PNT2258 is being developed by ProNAi Therapeutics, Inc. The company has completed 2 trials of PNT2258 to date—a phase 1 trial of patients with solid tumors and a phase 2 trial of patients with non-Hodgkin lymphoma.
The phase 1 trial enrolled 22 patients with relapsed or refractory solid tumor malignancies. Results were published in Cancer Chemotherapy and Pharmacology in February 2014.
PNT2258 was deemed well-tolerated in this trial. There was no evidence of a systemic immune response to the LNPs or PNT100. There were no significant changes in immune-stimulatory cytokines or clinical signs of anaphylaxis following PNT2258 administration.
The phase 2 trial enrolled 13 patients with relapsed or refractory non-Hodgkin lymphoma. Results were presented at ASH 2014 (abstract 1716).
Six patients responded to PNT2258—4 with complete responses and 2 with partial responses. Five patients had stable disease, and 2 progressed. All 4 of the DLBCL patients in this trial responded—3 with complete responses and 1 with a partial response.
Adverse events reported in this trial include nausea (n=11), pain (n=9), chills (n=7), diarrhea (n=7), vomiting (n=7), fatigue (n=6), fever (n=6), headache (n=6), dyspnea (n=5), generalized aching (n=4), anorexia (n=4), back pain (n=4), sensory neuropathy (n=4), hypophosphatemia (n=4), anemia (n=3), hypokalemia (n=3), hyperuricemia (n=2), neutropenia (n=2), thrombocytopenia (n=4), and elevated AST/ALT (n=1).
ProNAi Therapeutics is now enrolling patients in “Wolverine,” a phase 2 trial evaluating PNT2258 in patients with relapsed or refractory DLBCL, and in “Brighton,” a phase 2 trial evaluating PNT2258 for the treatment of Richter’s transformation.
The US Food and Drug Administration (FDA) has granted orphan designation to the oncology drug candidate PNT2258 for the treatment of diffuse large B-cell lymphoma (DLBCL).
The FDA grants orphan designation to drugs intended to treat conditions affecting fewer than 200,000 patients in the US.
The designation provides the drug’s sponsor with various development incentives, including opportunities to apply for research-related tax credits and grant funding, assistance in designing clinical trials, and 7 years of US market exclusivity if the drug is approved.
About PNT2258
PNT2258 is designed to target cancers that overexpress BCL2, and BCL2 overexpression is thought to be a key driver of DLBCL.
PNT2258 consists of a single-stranded, 24-base DNAi oligonucleotide known as PNT100 that is encapsulated in lipid nanoparticles (LNPs).

Gilead Sciences, Inc.
The European Medicines Agency (EMA) is reviewing the safety of idelalisib (Zydelig), a drug approved to treat chronic lymphocytic leukemia (CLL) and follicular lymphoma in the European Union (EU).
The European Commission (EC) requested the review because of serious adverse events (AEs), including deaths, reported in 3 clinical trials investigating idelalisib in combination with other drugs.
The AEs were mostly infection-related.
The EMA is reviewing data from these studies to assess whether the findings have any consequences for the authorized uses of idelalisib.
In the meantime, the EMA advises that patients starting or already on treatment with idelalisib be carefully monitored for signs of infections. If the drug is well tolerated, treatment should not be stopped.
The EMA is considering whether any other immediate measures are necessary during the review period. The agency said it will communicate further and keep doctors and patients informed as appropriate.
About idelalisib
In the EU, idelalisib is approved for use in combination with rituximab to treat adults with CLL who have received at least 1 prior therapy or as first-line treatment in the presence of 17p deletion or TP53 mutation in CLL patients unsuitable for chemo-immunotherapy.
Idelalisib is also approved as monotherapy for adults with follicular lymphoma that is refractory to 2 prior lines of treatment.
About the trials
The trials in which patients have experienced serious AEs involve patients with CLL and indolent non-Hodgkin lymphoma (NHL).
In one trial (NCT01732926), researchers are evaluating idelalisib in combination with bendamustine and rituximab for previously treated indolent NHL.
In another (NCT01732913), researchers are testing idelalisib in combination with rituximab for previously treated indolent NHL.
And in the third (NCT01980888), researchers are evaluating idelalisib in combination with bendamustine and rituximab in patients with previously untreated CLL.
The EMA noted that these studies are investigating combinations of drugs that are currently not approved in the EU and include patients with disease characteristics different from those covered by the approved indications for idelalisib.
About the review
The EMA has begun the review of idelalisib at the request of the EC, under Article 20 of Directive 2001/83/EC.
The review is being carried out by the EMA’s Pharmacovigilance Risk Assessment Committee, the committee responsible for the evaluation of safety issues for human medicines, which will make a set of recommendations.
Those recommendations will then be forwarded to the Committee for Medicinal Products for Human Use, which is responsible for questions concerning medicines for human use and will adopt a final opinion on the safety of idelalisib.
The final stage of the review procedure is the EC’s adoption of a legally binding decision that is applicable in all EU member states.

Program can predict drug side effects
Photo by Darren Baker
Scientists say they have developed a computer program that can predict whether or not a given pharmaceutical agent will produce certain side effects.
The software takes an “ensemble approach” to assessing the chemical structure of a drug molecule and can determine whether key substructures are present in the molecule that are known to give rise to side effects in other drugs.
Md Jamiul Jahid and Jianhua Ruan, PhD, both of the University of Texas at San Antonio, developed the computer program and described it in the International Journal of Computational Biology and Drug Design.
The pair tested the software’s ability to predict 1385 side effects associated with 888 marketed drugs and found that the program outperformed earlier software.
The team also used their new software to test 2883 uncharacterized compounds in the DrugBank database. The program proved capable of predicting a wide variety of side effects, including some effects that were missed by other screening methods.
The scientists believe their software could be used to alert regulatory authorities and healthcare workers as to what side effects might occur when a new drug enters late-stage clinical trials and is ultimately brought to market.
But the program may have an additional benefit as well. By identifying substructures that are associated with particular side effects, the software could be used to help medicinal chemists understand the underlying mechanism by which a side effect arises.
The chemists could then eliminate the offending substructures from drug molecules in the future, thereby reducing the number of drugs that go through the research and development pipeline and then fail in clinical trials due to severe side effects.

FDA lifts partial clinical hold on pidilizumab
The US Food and Drug Administration (FDA) has lifted the partial clinical hold on the investigational new drug (IND) application for pidilizumab (MDV9300) in hematologic malignancies.
This means the phase 2 trial of pidilizumab in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), as well as other studies that cross-reference the IND for the drug, may now proceed.
The partial clinical hold on pidilizumab was not related to any safety concerns.
The FDA placed the hold because the company developing pidilizumab, Medivation Inc., determined that the drug is not an inhibitor of PD-1, as researchers previously thought.
The phase 2 trial of pidilizumab in DLBCL was launched in late 2015 but had not enrolled any patients before the FDA placed the partial clinical hold.
Patients who were receiving pidilizumab through investigator-sponsored trials have continued to receive treatment despite the hold, and those investigators have been told to update their protocols and informed consent documents to reflect that pidilizumab is not an anti-PD-1 antibody.
Medivation has likewise revised the investigator brochure, protocols, and informed consent documents related to the phase 2 trial of DLBCL patients.
The company said it is still trying to determine pidilizumab’s mechanism of action.
“We are delighted that the FDA has lifted the partial clinical hold and that we may proceed with our potentially pivotal trial in this area of high unmet medical need,” said David Hung, MD, founder, president, and chief executive officer of Medivation.
“As we move forward, we also are working to determine the compound’s exact binding mechanism which, we believe, modulates the body’s innate immune response and differentiates it from the heavily crowded immuno-oncology space that targets the adaptive side of immunity.”
Medivation said it intends to submit an amendment to the Chemistry, Manufacturing, and Controls section of the IND for pidilizumab to provide for larger manufacturing lot sizes to better support the current and planned clinical activities for the drug.
The company also said it plans to resume the phase 2 trial of pidilizumab in DLBLCL in the second half of this year.
The trial is expected to enroll approximately 180 patients who had an incomplete response to salvage therapy or autologous stem cell transplant for relapsed or refractory CD20+ DLBCL, transformed indolent lymphoma, or primary mediastinal B-cell lymphoma.
The patients will be assessed in 2 parallel cohorts of approximately 90 patients each. One cohort will enroll patients who have received an autologous stem cell transplant, and the other will enroll patients who have received salvage chemotherapy but are ineligible for transplant.
Pidilizumab will be given at a dose of 200 mg by intravenous infusion. The primary endpoint of the trial is best overall response rate.

EMA initiative aims to accelerate drug development

The European Medicines Agency (EMA) has launched PRIME (PRIority MEdicines), an initiative intended to accelerate the development of drugs that target unmet medical needs.
These “priority medicines” may offer a major therapeutic advantage over existing treatments or benefit patients who currently have no treatment options in the European Union (EU).
Through PRIME, the EMA will offer early support to drug developers to optimize the generation of robust data on a treatment’s benefits and risks and enable accelerated assessment of an application for marketing authorization.
By engaging with developers early, the EMA aims to strengthen the design of clinical trials to facilitate the generation of high quality data to support an application for marketing authorization.
PRIME builds on the existing regulatory framework and available tools such as scientific advice and accelerated assessment.
To be accepted for PRIME, a treatment has to show the potential to benefit patients with unmet medical needs based on early clinical data.
Once a candidate medicine has been selected for PRIME, the EMA:
- Appoints a rapporteur from the Committee for Medicinal Products for Human Use (CHMP), or from the Committee on Advanced Therapies (CAT) in the case of an advanced therapy, to provide continuous support and help to build knowledge before a company submits an application for marketing authorization
- Organizes a kick-off meeting with the CHMP/CAT rapporteur and a multidisciplinary group of experts from relevant EMA scientific committees and working parties, and provides guidance on the overall development plan and regulatory strategy
- Assigns a dedicated EMA contact point
- Provides scientific advice at key development milestones, involving additional stakeholders such as health technology assessment bodies to facilitate quicker access to the new drug
- Confirms potential for accelerated assessment when an application for marketing authorization is submitted.
PRIME is open to all drug companies on the basis of preliminary clinical evidence. However, micro-, small- and medium-sized enterprises and applicants from the academic sector can apply earlier on the basis of compelling non-clinical data and tolerability data from initial clinical trials. They may also request fee waivers for scientific advice.
The EMA has released guidance documents on PRIME as well as a comprehensive overview of the EU early access regulatory tools—ie, accelerated assessment, conditional marketing authorization, and compassionate use.
The agency has also published revised guidelines on the implementation of accelerated assessment and conditional marketing authorization. These tools are reserved for treatments addressing major public health needs, and the revised guidelines provide more detailed information based on past experience.
Although PRIME is specifically designed to promote accelerated assessment, the EMA said the initiative will also help drug developers make the best use of other EU early access tools and initiatives, which can be combined whenever a drug fulfills the respective criteria.
PRIME was developed in consultation with the EMA’s scientific committees, the European Commission and its expert group on Safe and Timely Access to Medicines for Patients, as well as the European medicines regulatory network.
The main principles of PRIME were released for a 2-month public consultation in 2015, and the comments received were taken into account in the final version.

However, micro-, small- and medium-sized enterprises and applicants from the academic sector can apply earlier on the basis of compelling non-clinical data and tolerability data from initial clinical trials. They may also request fee waivers for scientific advice.
The EMA has released guidance documents on PRIME as well as a comprehensive overview of the EU early access regulatory tools—ie, accelerated assessment, conditional marketing authorization, and compassionate use.
The agency has also published revised guidelines on the implementation of accelerated assessment and conditional marketing authorization. These tools are reserved for treatments addressing major public health needs, and the revised guidelines provide more detailed information based on past experience.
Although PRIME is specifically designed to promote accelerated assessment, the EMA said the initiative will also help drug developers make the best use of other EU early access tools and initiatives, which can be combined whenever a drug fulfills the respective criteria.
PRIME was developed in consultation with the EMA’s scientific committees, the European Commission and its expert group on Safe and Timely Access to Medicines for Patients, as well as the European medicines regulatory network.
The main principles of PRIME were released for a 2-month public consultation in 2015, and the comments received were taken into account in the final version.

The European Medicines Agency (EMA) has launched PRIME (PRIority MEdicines), an initiative intended to accelerate the development of drugs that target unmet medical needs.
These “priority medicines” may offer a major therapeutic advantage over existing treatments or benefit patients who currently have no treatment options in the European Union (EU).
Through PRIME, the EMA will offer early support to drug developers to optimize the generation of robust data on a treatment’s benefits and risks and enable accelerated assessment of an application for marketing authorization.
By engaging with developers early, the EMA aims to strengthen the design of clinical trials to facilitate the generation of high quality data to support an application for marketing authorization.
PRIME builds on the existing regulatory framework and available tools such as scientific advice and accelerated assessment.
To be accepted for PRIME, a treatment has to show the potential to benefit patients with unmet medical needs based on early clinical data.
Once a candidate medicine has been selected for PRIME, the EMA:
- Appoints a rapporteur from the Committee for Medicinal Products for Human Use (CHMP), or from the Committee on Advanced Therapies (CAT) in the case of an advanced therapy, to provide continuous support and help to build knowledge before a company submits an application for marketing authorization
- Organizes a kick-off meeting with the CHMP/CAT rapporteur and a multidisciplinary group of experts from relevant EMA scientific committees and working parties, and provides guidance on the overall development plan and regulatory strategy
- Assigns a dedicated EMA contact point
- Provides scientific advice at key development milestones, involving additional stakeholders such as health technology assessment bodies to facilitate quicker access to the new drug
- Confirms potential for accelerated assessment when an application for marketing authorization is submitted.

FDA approves long-acting hemophilia B therapy
The US Food and Drug Administration (FDA) has approved Idelvion (Coagulation Factor IX [Recombinant], Albumin Fusion Protein) for the treatment of hemophilia B.
The product—a fusion protein linking recombinant coagulation factor IX with recombinant albumin—is intended for use in children and adults for routine prophylaxis to prevent or reduce the frequency of bleeding episodes, for on-demand control and prevention of bleeding episodes, and for the perioperative management of bleeding.
Appropriate patients age 12 and older can go up to 14 days between Idelvion infusions. This dosing interval has been achieved while maintaining high levels of factor IX activity—above 5% over 14 days at 75 IU/kg.
Idelvion is the first FDA-approved recombinant factor IX therapy that can extend the dosing interval up to 14 days.
Idelvion is expected to be available in the US later this month. The product is being developed by CSL Behring. For more details on the drug, see the full prescribing information.
Phase 3 trial
The FDA approved Idelvion based on results of the PROLONG-9FP clinical development program. PROLONG-9FP includes phase 1, 2, and 3 studies evaluating the safety and efficacy of Idelvion in adults and children (ages 1 to 61) with hemophilia B.
Data from the phase 3 study were recently published in Blood. This study included 63 previously treated male patients with severe hemophilia B. They had a mean age of 33 (range, 12 to 61).
The patients were divided into 2 groups. Group 1 (n=40) received routine prophylaxis with Idelvion once every 7 days for 26 weeks, followed by a 7-, 10- or 14-day prophylaxis regimen for a mean of 50, 38, or 51 weeks, respectively.
Group 2 received on-demand treatment with Idelvion for bleeding episodes for 26 weeks (n=23) and then switched to a 7-day prophylaxis regimen for a mean of 45 weeks (n=19).
The median annualized bleeding rate (ABR) was 2.0 in the prophylaxis arm (group 1) and 23.5 in the on-demand treatment arm (group 2). The median spontaneous ABRs were 0.0 and 17.0, respectively.
For patients in group 2, there was a significant reduction in median ABRs when patients switched from on-demand treatment to prophylaxis—19.22 and 1.58, respectively (P<0.0001). And there was a significant reduction in median spontaneous ABRs—15.43 and 0.00, respectively (P<0.0001).
Overall, 98.6% of bleeding episodes were treated successfully, including 93.6% that were treated with a single injection of Idelvion.
None of the patients developed inhibitors or experienced thromboembolic events, anaphylaxis, or life-threatening adverse events (AEs).
There were 347 treatment-emergent AEs reported in 54 (85.7%) patients. The most common were nasopharyngitis (25.4%), headache (23.8%), arthralgia (4.3%), and influenza (11.1%).
Eleven mild/moderate AEs in 5 patients (7.9%) were considered possibly related to Idelvion. Two patients discontinued treatment due to AEs—1 with hypersensitivity and 1 with headache.
