The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended approval for Obizur, a recombinant porcine

factor VIII (FVIII) product, to treat bleeding episodes in adults with acquired hemophilia A.

If the European Commission approves Obizur, it will be the first recombinant porcine FVIII treatment available in the European Union (EU) for this patient population. Obizur already has orphan designation in the EU.

The European Commission is expected to make a decision on Obizur later this year. The decision will be applicable to all 28 EU member states plus Iceland, Norway, and Liechtenstein.

About Obizur

Acquired hemophilia A is caused by the formation of antibodies directed against the body’s own FVIII. The underlying cause of this may be pregnancy, cancer, or the use of certain medications, but the cause is often unknown.

Obizur replaces inhibited human FVIII with a recombinant porcine sequence FVIII based on the rationale that porcine FVIII is less susceptible to inactivation by circulating human FVIII antibodies. Physicians can monitor patients’ response to Obizur by measuring FVIII activity levels.

The CHMP’s positive opinion of Obizur is based on a phase 2/3 trial in which patients with acquired hemophilia A received the drug as treatment for serious bleeding episodes.

Twenty-nine patients were enrolled and evaluated for safety. Researchers determined that one of the patients did not actually have acquired hemophilia A, so this patient could not be evaluated for efficacy.

At 24 hours after the initial infusion, all 28 patients in the efficacy analysis had a positive response to Obizur. This meant that bleeding stopped or decreased, the patients experienced clinical stabilization or improvement, and FVIII levels were 20% or higher.

Eighty-six percent of patients (24/28) had successful treatment of their initial bleeding episode. The overall treatment success was determined by the investigator based on the ability to discontinue or reduce the dose and/or dosing frequency of Obizur.

The adverse event most frequently reported in the 29 patients in the safety analysis was the development of inhibitors to porcine FVIII.

Nineteen patients were negative for anti-porcine FVIII antibodies at baseline, and 5 of these patients (26%) developed anti-porcine FVIII antibodies following exposure to Obizur.

Of the 10 patients with detectable anti-porcine FVIII antibodies at baseline, 2 (20%) experienced an increase in titer, and 8 (80%) decreased to a non-detectable titer.

Obizur is under development by Baxalta Incorporated. The product is already approved in the US and is under regulatory review in Canada, Switzerland, Australia, and Colombia.

A new study indicates that drug manufacturers fail to report about 10% of serious and unexpected adverse events (AEs) within the timeframe set out in federal regulations.

Manufacturers are required to report a serious AE (death, hospitalization, disability, etc.) or unexpected AE (anything not listed in the drug’s label) to the US Food and Drug Administration (FDA) within 15 calendar days of learning about the event.

But an analysis of more than 1.6 million AE reports showed that manufacturers failed to meet this requirement for nearly 10% of AEs.

Pinar Karaca-Mandic, PhD, of the University of Minnesota School of Public Health in Minneapolis, and her colleagues conducted the analysis and detailed the results in JAMA Internal Medicine.

The team examined data from the FDA Adverse Event Reporting System for AE reports made from January 2004 through June 2014. The final study sample included only reports that were subject to the regulation requiring submission within 15 days—a total of 1,613,079 reports.

The researchers found that 9.94% of reports were not received by the FDA within the 15-day timeframe. This was a total of 160,383 reports—40,464 cases in which patients died and 119,919 in which they did not.

So 90.06% of reports (n=1,452,696) were reported within 15 days, 5.28% (n=85,161) were reported within 16 to 90 days, 2.19% (n=35,392) were reported within 91 to 180 days, and 2.47% (n=39,830) were reported after 180 days.

Multivariate analysis revealed that patient death was positively associated with delayed AE reporting. About 91% (90.71%) of AEs that did not involve death were reported within 15 days, compared to 88.25% of AEs that did involve death.

The percentage of reports received within 16 to 90 days was 5.19% for AEs without death and 6.42% for AEs with death. The percentage of reports received within 91 to 180 days was 1.98% and 2.53%, respectively. And the percentage of reports received after 180 days was 2.12% and 2.80%, respectively.

The researchers said perhaps manufacturers spend additional time verifying reports concerning deaths, but this discretion is outside the scope of the current regulatory regime.

In a related Editor’s Note, Rita F. Redberg, MD, editor of JAMA Internal Medicine, wrote that delays in reporting AEs should never occur because they mean exposing patients to serious harm, including death, that could potentially be avoided.

“One improvement would be for AE reports to go directly to the FDA instead of via the manufacturer . . . ,” she wrote. “Physicians and their patients must be knowledgeable of benefits, harms, and alternatives for a wide choice of treatments, especially those recently approved for which clinical experience is limited.”

The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended approval for eltrombopag (Revolade) as a treatment for adults with severe aplastic anemia (SAA) who have had an insufficient response to immunosuppressive therapy (IST) and are not eligible to receive a hematopoietic stem cell transplant (HSCT).

If approved by the European Commission, eltrombopag would be the first treatment option in its class for these patients.

The European Commission will review the CHMP recommendation and is expected to deliver its final decision within 3 months. The decision will be applicable to all 28 European Union member states plus Iceland, Norway, and Liechtenstein.

Phase 2 trial of eltrombopag in SAA

The CHMP’s positive opinion of eltrombopag is mainly based on results of a phase 2 trial (NCT00922883). Results from this ongoing study were published in NEJM in 2012 and Blood in 2013.

The trial has enrolled 43 patients with SAA who had an insufficient response to at least one prior IST and who had a platelet count of 30 x 10⁹/L or less.

At baseline, the median platelet count was 20 x 10⁹/L, hemoglobin was 8.4 g/dL, the absolute neutrophil count was 0.58 x 10⁹/L, and absolute reticulocyte count was 24.3 x 10⁹/L.

Patients had a median age of 45 (range, 17 to 77), and 56% were male. The majority of patients (84%) received at least 2 prior ISTs.

Patients received eltrombopag at an initial dose of 50 mg once daily for 2 weeks. The dose increased over 2-week periods to a maximum of 150 mg once daily.

The study’s primary endpoint was hematologic response, which was initially assessed after 12 weeks of treatment. Treatment was discontinued after 16 weeks in patients who did not exhibit a hematologic response.

Forty percent of patients (n=17) experienced a hematologic response in at least one lineage—platelets, red blood cells (RBCs), or white blood cells—after week 12.

In the extension phase of the study, 8 patients achieved a multilineage response. Four of these patients subsequently tapered off treatment and maintained the response. The median follow up was 8.1 months (range, 7.2 to 10.6 months).

Ninety-one percent of patients were platelet-transfusion-dependent at baseline. Patients who responded to eltrombopag did not require platelet transfusions for a median of 200 days (range, 8 to 1096 days).

Eighty-six percent of patients were RBC-transfusion-dependent at baseline. Patients who responded to eltrombopag did not require RBC transfusions for a median of 208 days (range, 15 to 1082 days).

The most common adverse events (≥20%) associated with eltrombopag were nausea (33%), fatigue (28%), cough (23%), diarrhea (21%), and headache (21%).

Patients were also evaluated for cytogenetic abnormalities. Eight patients had a new cytogenetic abnormality after treatment, including 5 patients who had complex changes in chromosome 7.

Patients who develop new cytogenetic abnormalities while on eltrombopag may need to be taken off treatment.

About eltrombopag

Eltrombopag is already approved to treat SAA in the US and Canada. The drug recently gained approval in the US to treat children age 6 and older who have chronic immune thrombocytopenia and have had an insufficient response to corticosteroids, immunoglobulins, or splenectomy.

Eltrombopag is approved in more than 100 countries to treat adults with chronic immune thrombocytopenia who have had an inadequate response to or are intolerant of other treatments. The drug is approved in more than 45 countries for the treatment of thrombocytopenia in patients with chronic hepatitis C to allow them to initiate and maintain interferon-based therapy.

Eltrombopag is marketed under the brand name Promacta in the US and Revolade in most other countries. For more details on the drug, see the European Medicines Agency’s Summary of Product Characteristics.

Carfilzomib (Kyprolis)

The US Food and Drug Administration (FDA) has approved carfilzomib (Kyprolis) in combination with lenalidomide and dexamethasone to treat patients with relapsed multiple myeloma (MM) who have received 1 to 3 prior lines of therapy.

Carfilzomib already has accelerated approval from the FDA as monotherapy for MM patients who have received at least 2 prior therapies, including bortezomib and an immunomodulatory agent, and have demonstrated disease progression on or within 60 days of completing their last treatment.

The FDA’s expanded approval was based on results of the phase 3 ASPIRE trial.

The trial enrolled 792 patients with relapsed or refractory MM who had received 1 to 3 prior lines of therapy. The patients were randomized (1:1) to receive lenalidomide and dexamethasone with or without carfilzomib for 18 cycles.

Lenalidomide and dexamethasone were continued thereafter until disease progression. There was no planned cross-over from the control arm to treatment with carfilzomib.

There was a statistically significant prolongation of progression-free survival (PFS), as determined by an independent review committee, in the carfilzomib arm (hazard ratio=0.69, P=0.0001). The median PFS was 26.3 months in the 3-drug arm and 17.6 months in the 2-drug arm.

A treatment effect was observed across all subgroups tested, but the magnitude of the treatment effect was reduced in patients with higher tumor burden at baseline. The improvement in median PFS was 11 months for patients with International Staging System (ISS) Stage I disease, 8 months for ISS Stage II, and 2 months for ISS Stage III.

An interim analysis of overall survival, the key secondary endpoint, was conducted at the same time. The difference in overall survival did not reach the prespecified boundary for statistical significance.

The overall response rate (partial response or better) was 87% in the 3-drug arm and 67% in the 2-drug arm.

The safety profile of carfilzomib in the 3-drug combination was similar to that described on the current label.

Cardiovascular events, venous thromboembolic events (VTE), and thrombocytopenia occurred more frequently in the 3-drug arm than in the 2-drug arm. In cycles 1 to 12, the VTE rate was 13% and 6%, respectively, despite protocol-mandated use of thromboprophylaxis.

The revised labeling for carfilzomib includes new Warnings and Precautions for VTE, cardiac toxicities, acute renal failure, pulmonary toxicities, and hypertension. The increased safety risks, including mortality, for elderly patients is described. Detailed safety information in the prescribing information was also updated for the use of carfilzomib monotherapy.

The recommended dose schedule for carfilzomib has been revised for both monotherapy and combination treatment. For details, see the full prescribing information.

Carfilzomib is marketed as Kyprolis in the US by Onyx Pharmaceuticals, Inc., an Amgen subsidiary.

Cardiovascular events, venous thromboembolic events (VTE), and thrombocytopenia occurred more frequently in the 3-drug arm than in the 2-drug arm. In cycles 1 to 12, the VTE rate was 13% and 6%, respectively, despite protocol-mandated use of thromboprophylaxis.

The revised labeling for carfilzomib includes new Warnings and Precautions for VTE, cardiac toxicities, acute renal failure, pulmonary toxicities, and hypertension. The increased safety risks, including mortality, for elderly patients is described. Detailed safety information in the prescribing information was also updated for the use of carfilzomib monotherapy.

The recommended dose schedule for carfilzomib has been revised for both monotherapy and combination treatment. For details, see the full prescribing information.

The US Food and Drug Administration (FDA) has approved carfilzomib (Kyprolis) in combination with lenalidomide and dexamethasone to treat patients with relapsed multiple myeloma (MM) who have received 1 to 3 prior lines of therapy.

Carfilzomib already has accelerated approval from the FDA as monotherapy for MM patients who have received at least 2 prior therapies, including bortezomib and an immunomodulatory agent, and have demonstrated disease progression on or within 60 days of completing their last treatment.

The FDA’s expanded approval was based on results of the phase 3 ASPIRE trial.

The trial enrolled 792 patients with relapsed or refractory MM who had received 1 to 3 prior lines of therapy. The patients were randomized (1:1) to receive lenalidomide and dexamethasone with or without carfilzomib for 18 cycles.

Lenalidomide and dexamethasone were continued thereafter until disease progression. There was no planned cross-over from the control arm to treatment with carfilzomib.

There was a statistically significant prolongation of progression-free survival (PFS), as determined by an independent review committee, in the carfilzomib arm (hazard ratio=0.69, P=0.0001). The median PFS was 26.3 months in the 3-drug arm and 17.6 months in the 2-drug arm.

A treatment effect was observed across all subgroups tested, but the magnitude of the treatment effect was reduced in patients with higher tumor burden at baseline. The improvement in median PFS was 11 months for patients with International Staging System (ISS) Stage I disease, 8 months for ISS Stage II, and 2 months for ISS Stage III.

An interim analysis of overall survival, the key secondary endpoint, was conducted at the same time. The difference in overall survival did not reach the prespecified boundary for statistical significance.

The overall response rate (partial response or better) was 87% in the 3-drug arm and 67% in the 2-drug arm.

The safety profile of carfilzomib in the 3-drug combination was similar to that described on the current label.

Micrograph showing MM

The US Food and Drug Administration (FDA) has granted orphan designation for the drug CB-5083 to treat multiple myeloma (MM).

CB-5083 works by inhibiting p97, an enzyme that controls various aspects of protein homeostasis.

Inhibiting p97 function in cancers has been shown to generate irresolvable endoplasmic reticulum stress that induces a lethal unfolded protein response, which leads to apoptosis and antitumor activity.

CB-5083 has exhibited anticancer activity in preclinical research, and the drug is currently under investigation in two phase 1 studies—one in MM and one in solid tumor malignancies.

Research in MM

Preclinical research presented at ASH 2014 showed that CB-5083 inhibits MM cell viability in vitro. The drug also inhibited tumor growth in xenograft models of MM and in an orthometastatic model of MM.

In addition, CB-5083 demonstrated synergy with carfilzomib, bortezomib, and combination lenalidomide-dexamethasone.

CB-5083 is now under investigation in a phase 1 dose-escalation/dose-expansion trial of MM patients.

Researchers are evaluating the safety, pharmacokinetics, pharmacodynamics, and antitumor activity of the drug in patients who have relapsed/refractory or refractory MM after receiving 2 or more lines of therapy, including an immunomodulatory agent and a proteasome inhibitor.

The goal is to enroll up to 60 patients in this trial at multiple US cancer centers that are part of the Multiple Myeloma Research Consortium. More information about the trial is available at www.clinicaltrials.gov (NCT02223598).

About orphan designation

The FDA grants orphan designation to drugs that are intended to treat diseases or conditions affecting fewer than 200,000 patients in the US. Orphan designation provides the sponsor of a drug with various development incentives.

The orphan designation for CB-5083 provides Cleave Biosciences with opportunities to apply for research-related tax credits and grant funding, assistance in designing clinical trials, 7 years of US marketing exclusivity if the drug is approved, and other benefits.

The UK’s National Institute for Health and Care Excellence (NICE) has issued a draft guidance recommending the oral anticoagulant edoxaban tosylate (Lixiana) as an option for treating and preventing the recurrence of venous thromboembolism (VTE).

A committee advising NICE concluded that edoxaban is clinically effective, and the drug will be a cost-effective use of National Health Service resources.

“The newer oral anticoagulants like edoxaban tosylate are an alternative to warfarin as the mainstay of treatment to prevent recurrent blood clots,” said Carole Longson, NICE Health Technology Evaluation Centre Director.

“The committee concluded that patients value newer oral anticoagulants such as edoxaban tosylate, which cause less disruption to their day-to-day lives than warfarin. We are pleased, therefore, to be able to recommend edoxaban tosylate as a further cost-effective option for treating [VTE] and preventing further episodes in adults.”

Clinical effectiveness

Edoxaban was recently approved in the European Union to treat and prevent deep vein thrombosis (DVT) and pulmonary embolism (PE). This approval was based on results of the Hokusai-VTE trial. The committee advising NICE analyzed data from this trial when considering the clinical effectiveness of edoxaban.

For Hokusai-VTE, researchers evaluated edoxaban in 4921 patients with DVT and 3319 with PE. Patients received initial treatment with low-molecular-weight heparin and were then randomized to receive edoxaban or warfarin daily for 3 to 12 months.

Overall, edoxaban proved as effective as warfarin. Recurrent, symptomatic VTE occurred in 3.2% and 3.5% of patients, respectively (P<0.001 for non-inferiority).

In addition, the incidence of clinically relevant bleeding was significantly lower in the edoxaban arm than the warfarin arm—8.5% and 10.3%, respectively (P=0.004 for superiority).

Cost-effectiveness

The recommended dose of edoxaban is 60 mg once daily, or 30 mg once daily in specific patient groups—those with renal impairment, low body weight (60 kg or less), or concomitant use of potent permeability glycoprotein inhibitors—following treatment with a parenteral anticoagulant for at least 5 days.

Edoxaban costs £2.10 per 15 mg, 30 mg, or 60 mg tablet (excluding value-added tax). Costs may vary in different settings because of negotiated procurement discounts.

Taking into account the lack of any clear evidence that edoxaban is significantly different from the other new oral anticoagulants, as well as the testimony of experts, the committee advising NICE concluded that the most plausible incremental cost-effectiveness ratio for edoxaban was likely to be in line with the other oral anticoagulants already recommended by NICE.

The draft guidance for edoxaban is now with consultees, who have the opportunity to appeal against it. Once NICE issues its final guidance on a technology, it replaces local recommendations.

Micrograph showing WM

The European Commission has granted marketing authorization for ibrutinib (Imbruvica) to treat Waldenstrom’s macroglobulinemia (WM).

The Bruton’s tyrosine kinase inhibitor is now approved to treat adults with WM who have received at least one prior therapy or as first-line treatment for patients considered unsuitable for chemo-immunotherapy.

Ibrutinib is the first therapy approved specifically for WM in the European Union (EU). The approval applies to all 28 EU member states, plus Iceland, Norway, and Liechtenstein.

Ibrutinib is already approved to treat WM in the US. The drug is also approved in the EU, the US, and other countries to treat chronic lymphocytic leukemia and mantle cell lymphoma.

Janssen-Cilag International NV holds the marketing authorization for ibrutinib in Europe, and its affiliates market the drug in Europe and the rest of the world. In the US, ibrutinib is under joint development by Pharmacyclics and Janssen Biotech, Inc.

Phase 2 study

The European Commission’s approval of ibrutinib was based on a multicenter, phase 2 study in which researchers tested the drug (given at 420 mg once daily) in 63 patients with previously treated WM.

Initial data showed an overall response rate of 87.3% in patients who received the drug for a median of 11.7 months.

Updated results from the study were published in NEJM in April. After a median treatment duration of 19.1 months, the overall response rate was 91%.

At 24 months, the estimated rate of progression-free survival was 69%, and the estimated rate of overall survival was 95%.

The most common grade 2-4 adverse events were neutropenia (22%) and thrombocytopenia (14%). Ibrutinib-related neutropenia and thrombocytopenia were reversible but required a dose reduction in 3 patients and treatment discontinuation in 4 patients.

Grade 2 or higher bleeding events occurred in 4 patients, and there were 15 infections considered possibly related to ibrutinib.

Treatment-related atrial fibrillation (AFib) occurred in 3 patients, all of whom had a prior history of paroxysmal AFib. AFib resolved when treatment was withheld, and all 3 patients were able to continue on therapy per protocol without an additional event.

The European Commission (EC) has approved edoxaban (Lixiana), an oral factor Xa inhibitor, for use in patients with venous thromboembolism (VTE) or nonvalvular atrial fibrillation (NVAF).

The drug can now be used to treat and prevent the recurrence of deep vein thrombosis (DVT) and pulmonary embolism (PE).

It can also be used to prevent stroke and systemic embolism in adults with NVAF who have one or more risk factors for stroke or systemic embolism, such as congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, prior stroke, or transient ischemic attack.

The EC’s decision affects all 28 European Union member states, plus Iceland, Norway, and Liechtenstein. Edoxaban is already approved for use in the US, Japan, and Switzerland.

The EC based its approval of edoxaban on results of 2 phase 3 clinical trials, ENGAGE AF-TIMI 48 and Hokusai-VTE.

Hokusai-VTE

In the Hokusai-VTE trial, researchers evaluated edoxaban in 4921 patients with DVT and 3319 with PE. Patients received initial treatment with low-molecular-weight heparin and were then randomized to receive edoxaban or warfarin daily for 3 to 12 months.

In addition, the incidence of clinically relevant bleeding was significantly lower in the edoxaban arm than the warfarin arm—8.5% and 10.3%, respectively (P=0.004 for superiority).

ENGAGE-AF TIMI 48

In the ENGAGE AF-TIMI 48 trial, researchers compared edoxaban and warfarin as prophylaxis for stroke or systemic embolism in patients with NVAF.

The trial included 21,105 patients who were randomized to receive warfarin (n=7036), edoxaban at 60 mg (n=7035), or edoxaban at 30 mg (n=7034).

Edoxaban was at least non-inferior to warfarin with regard to efficacy. The annual incidence of stroke or systemic embolism was 1.50% with warfarin, 1.18% with edoxaban at 60 mg (P<0.001 for non-inferiority), and 1.61% with edoxaban at 30 mg (P=0.005 for non-inferiority).

In addition, edoxaban was associated with a significantly lower rate of major and fatal bleeding. The annual incidence of major bleeding was 3.43% with warfarin, 2.75% with edoxaban at 60 mg (P<0.001), and 1.61% with edoxaban at 30 mg (P<0.001).

Fatal bleeds occurred at an annual rate of 0.38% with warfarin, 0.21% with edoxaban at 60 mg (P=0.006), and 0.13% with edoxaban at 30 mg (P<0.001).

Edoxaban was at least non-inferior to warfarin with regard to efficacy. The annual incidence of stroke or systemic embolism was 1.50% with warfarin, 1.18% with edoxaban at 60 mg (P<0.001 for non-inferiority), and 1.61% with edoxaban at 30 mg (P=0.005 for non-inferiority).

In addition, edoxaban was associated with a significantly lower rate of major and fatal bleeding. The annual incidence of major bleeding was 3.43% with warfarin, 2.75% with edoxaban at 60 mg (P<0.001), and 1.61% with edoxaban at 30 mg (P<0.001).

Fatal bleeds occurred at an annual rate of 0.38% with warfarin, 0.21% with edoxaban at 60 mg (P=0.006), and 0.13% with edoxaban at 30 mg (P<0.001).

Edoxaban is under development by Daiichi Sankyo Co., Ltd.

The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) is recommending regulatory approval for panobinostat (Farydak) to treat relapsed and/or refractory multiple myeloma (MM).

The drug is indicated for use in combination with bortezomib and dexamethasone to treat adults with MM who have received at least 2 prior treatment regimens, including bortezomib and an immunomodulatory agent (IMiD).

Panobinostat is already approved for this indication in the US and Chile.

If the European Commission follows the CHMP’s recommendation, panobinostat will be the first histone deacetylase (HDAC) inhibitor approved to treat MM in the European Union.

The European Commission generally follows CHMP recommendations and delivers its final decision within 3 months of the recommendation. The decision will be applicable to all 28 European Union member states, plus Iceland, Norway, and Liechtenstein.

“Panobinostat is the first and only HDAC inhibitor recommended by the CHMP for the treatment of patients living with multiple myeloma who have progressed after standard-of-care therapy with bortezomib and an IMiD,” said Alessandro Riva, MD, Global Head of Oncology Development and Medical Affairs at Novartis Oncology, the company developing panobinostat.

“We are pleased with the positive CHMP opinion on panobinostat for previously treated patients because it brings us one step closer to providing a new treatment option for patients in need in Europe.”

The CHMP’s recommendation is based on efficacy and safety data in a subgroup analysis of 147 patients on the phase 3 PANORAMA-1 trial. Results from this analysis were recently presented at the 2015 ASCO Annual Meeting.

PANORAMA-1 was designed to compare panobinostat in combination with bortezomib and dexamethasone to bortezomib and dexamethasone alone in patients who had relapsed or relapsed and refractory MM.

At ASCO, researchers presented results in 147 patients who had received 2 or more prior treatment regimens, including bortezomib and an IMiD.

The patients who received panobinostat, bortezomib, and dexamethasone had a longer median progression-free survival than patients who received bortezomib and dexamethasone alone—12.5 months and 4.7 months, respectively (hazard ratio=0.47).

Common grade 3/4 adverse events in both treatment arms were thrombocytopenia, lymphopenia, neutropenia, diarrhea, asthenia/fatigue, and peripheral neuropathy. About 7% of patients in both arms died while on treatment.

The US Food and Drug Administration (FDA) has granted a novel vaccine orphan designation as a treatment for multiple myeloma (MM).

The vaccine, known as ImMucin, targets the signal peptide domain of the MUC1 tumor antigen.

ImMucin works by “teaching” the immune system to identify and destroy cells that display a short, specific, 21-mer portion from MUC1, which appears on 90% of all cancer cells but not in patients’ blood.

Results of a phase 1/2 trial suggested that ImMucin was safe and active in MM patients. The trial included 15 MUC1-positive patients who had residual or biochemically progressive disease after autologous stem cell transplant.

The patients received 6 or 12 bi-weekly intradermal doses of ImMucin co-administered with human granulocyte-macrophage colony-stimulating factor.

The researchers said the vaccine was well-tolerated, as all adverse events were temporary, grade 1-2 in nature, and resolved spontaneously.

There was a significant decrease in soluble MUC1 levels in 9 patients, and 11 patients had stable disease or clinical improvement that persisted for 17.5 months to more than 41.3 months.

A follow-on study (which is ongoing) in patients who responded to ImMucin has shown that some patients can go more than 4 years without requiring any further treatment for their disease.

ImMucin is under development by Vaxil Biotherapeutics Ltd. The vaccine also has orphan designation as a treatment for MM in the European Union.

About orphan designation

The FDA grants orphan designation to encourage companies to develop therapies for diseases that affect fewer than 200,000 individuals in the US.

Orphan designation provides a company with research and development tax credits, an opportunity to obtain grant funding, exemption from FDA application fees, and other benefits.

If the FDA approves ImMucin to treat patients with MM, orphan designation will provide Vaxil Biotherapeutics with 7 years of marketing exclusivity in the US.
