Monitoring International Trends

posted August 2015

The NBA monitors international developments that may influence the management of blood and blood products in Australia. Our focus is on:

  • Potential new product developments and applications;
  • Global regulatory and blood practice trends;
  • Events that may have an impact on global supply, demand and pricing, such as changes in company structure, capacity, organisation and ownership; and
  • Other emerging risks that could potentially put financial or other pressures on the Australian sector.

1.Products

Here the NBA follows the progress in research and clinical trials that may within a reasonable timeframe make new products available, or may lead to new uses or changes in use for existing products.

Clotting factors

a)Pivotal data for Baxalta’s BAX 855 was published in the journal Blood. The company says the drug has the potential to provide strong bleed prevention in haemophilia A patients with twice weekly dosing. The drug is based on Advate and when approved by the FDA will be marketed in the US as Adynovate. The trial showed a mean half-life extension of 1.4 to 1.5fold compared with Advate. Baxalta expects to file for marketing authorization with the European Medicines Agency in 2016. A regulatory application was filed in Japan earlier this year.

b)Baxalta announced the publication[1] of pivotal phase III data for BAX 111, a highly purified recombinant von Willebrand factor (rVWF) candidate. The data showed that 100 per cent of the patients treated with BAX 111 achieved success in the management of bleeding episodes[2].BAX 111 is currently under review by the US Food and Drug Administration (FDA). If approved, BAX 111 would become the first recombinant replacement treatment for managing bleeding episodes for von Willebrand patients. BAX 111 was developed using a plasma- and albumin-free manufacturing method.Both the FDA and the European Medicines Agency granted orphan drug designation in November 2010, which is reserved for products that meet medical needs for a disease that is classified as rare.

Other

a)CSL is recruiting 1200 patients for a Phase IIB study of its drug CSL112 for acute coronary syndrome, designed to prevent a second heart attack after a patient has already suffered the first.

b)A study conducted at the Royal Free Hospital in Kuala Lumpur suggested that patients with gastrointestinal symptoms related to systemic sclerosis may benefit from treatment with intravenous immunoglobulin[3]

c)Researchers from Pohang University of Science and Technology reported “a new light-activated, mussel protein-based bioadhesive (LAMBA) inspired by mussel adhesion and insect dityrosine crosslinking chemistry. LAMBA exhibited substantially stronger bulk wet tissue adhesion than commercially available fibrin glue and good biocompatibility in both invitro and invivo studies”[4]. The researchers praised the potential of their product assurgical glue for sutureless wound closures, both internal and external.

d)Israeli startup LifeBond has developed a firm but elastic hydrogel matrix using a combination of gelatin and microbial transglutaminase (mTG) enzyme. Investors have now made $US 27 million available to fund a US trial of this LifeSeal Surgical Sealant in minimizing postoperative complications such as staple-line leakage in gastro-intestinal and bariatric surgeries. The product has previously undergone a multinational, randomized controlled pilot in Europe and is expected to be granted a CE mark.

e)Vic Convertino (senior scientist for the US Army Combat Casualty Care Research program at Joint Base San Antonio in Texas) and his fellow researchers say they are nearing approval by the FDA for a small device[5] that allows trauma medics to monitor precisely the rate at which a bleeding patient will reach “decompensation,” the point when the body can no longer offset blood loss, shock sets in and death soon follows. Such a device could be of use on the battlefield, where a blood pressure monitor may not indicate much change even when a soldier is losing a significant amount of blood.

2.Regulatory

The NBA monitors overseas regulatory decisions on products, processes or procedures which are or may be of relevance to its responsibilities.

Plasma and recombinant products

a)Baxalta announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency expressed a positive opinion for the marketing authorization of Obizur [Antihaemophilic Factor (Recombinant), Porcine Sequence]. Baxalta requested authorization for the treatment of bleeding episodes in adult patients with acquired haemophilia[6] caused by antibodies to Factor VIII (FVIII).The European Commission has yet to announce its decision on the recommendation[7]. John Orloff, head of Research & Development and chief scientific officer, Baxalta, said: “The marketing authorization anticipated later this year for Obizur will be an important milestone, offering patients with acquired haemophilia A in Europe a treatment option that transforms their care by allowing physicians to monitor treatment response”. The CHMP positive opinion follows a global, prospective, controlled, multi-centre Phase II/III open-label clinical trial testing the efficacy of Obizur in treating serious bleeding episodes in adults with acquired haemophilia A. All 28 patients treated with Obizur had their bleeding stopped or decreased. Adverse reactions were development of inhibitors to porcine FVIII. Obizur is already approved in the US and is being reviewed by regulators in Australia, Canada, Switzerland, and Colombia.

b)The FDA accepted for review CSL Behring's Biologics License Application (BLA) for its recombinant factor VIII single-chain (rVIIISingleChain or CSL 627), designed for molecular stability in treating haemophilia A. The product met all primary endpoints in the pivotal trial. The BLA relies on the AFFINITY clinical development program, including a phase I/III open-label, multi-centre trial examining safety and efficacy. Pharmacokinetics were compared with a current standard of care, recombinant human anti-haemophilic factor VIII (octocog alfa). CSL627 has a strong affinity for von Willebrand factor, leading to greater stability and integrity of FVIII in circulation.

c)Swissmedic accepted for review a Marketing Authorization Application for CSL Behring’s long-acting fusion protein linking recombinant coagulation factor IX with recombinant albumin (rIX-FP) for the prophylaxis and treatment of bleeding episodes in haemophilia B. This rIX-FP allows dosing intervals up to 14 days.

d)Baxalta announced in the US that the Centers for Medicare and Medicaid Services (CMS) have expanded coverage to include in-home use of Hyqvia [Immune Globulin Infusion 10% (Human) with Recombinant Human Hyaluronidase], a treatment for adults with primary immunodeficiency (PI). After the FDA approved Hyqvia in 2014, CMS covered both provider facility and in-office treatment with Hyqvia. This new decision expands its provisions to include durable medical equipment coverage of the infusion pump required to administer Hyqvia, facilitating the self-administration (at home) option for patients. In the clinical trial for Hyqvia, the majority of PI patients expressed a desire for the ability to administer infusions at home.

e)ADMA Biologics has submitted its Biologics License Application to the FDA seeking marketing authorization for RI-002. This is a plasma-derived, polyclonal, intravenous immune globulin derived from human plasma containing naturally occurring polyclonal antibodies (Streptococcus pneumoniae, H. influenza type B, cytomegalovirus (CMV), measles, tetanus, etc.) as well as standardized, high levels of antibodies to respiratory syncytial virus (RSV)[8]. In a Phase III study in patients with primary immunodeficiency, RI-002 met its primary endpoint of no serious bacterial infections (SBI). The requirement specified by FDA guidance is ≤ 1 SBI per patient-year.

Other

a)FDA officials have met with Google to “begin a discussion on how we might collaborate with Google on identifying adverse event data, using Google’s technologies and data.”[9]

b)The FDA granted Fresenius Kabi approval for a labelling change that permits blood centres to use the Fenwal Amicus system for the storage of Amicus-derived platelets in plasma for up to seven days. Where blood centres do store apheresis-derived platelets for seven days they must label each product with a statement that the product must be tested with a bacterial detection device cleared by FDA and labelled as a “safety measure”. Fresenius Kabi is the sole distributor of the Verax Platelet PGD test, a rapid test approved by the FDA as a “safety measure” for leukoreduced apheresis platelets within 24 hours prior to transfusion.

c)Hospira received approval from the FDA to launch bivalirudin for injection, a generic version of The Medicines Company's Angiomax. Bivalirudin is a direct thrombin inhibitor indicated amongst other things for use as an anticoagulant in patients with unstable angina undergoing percutaneous transluminal coronary angioplasty.

d)The FDA, the US Department of Homeland Security’s Industrial Control Systems Cyber Emergency Response Team, and Hospira announced that Hospira’s Symbiq Infusion System could be accessed remotely through a hospital’s network. An unauthorized user could control the device and change the dosage the pump delivers. While neither the FDA nor Hospira are aware of any unauthorized access of a Symbiq Infusion System in a US health care setting, the FDA urged health care facilities to discontinue use of these pumps.
