Biodel's Glucagon Formulation for Use in a Proprietary Auto-Reconstitution Device for the Treatment of Severe Hypoglycemia Meets Primary Efficacy Endpoint in Phase 1 Clinical Trial

BIOD-961 Administration Results in Glucagon Exposure and Glucose Response That Meets Standard Bioequivalence Criteria When Compared to Marketed Glucagon; Conference Call and Webcast Will be Held on Monday, March 16, 2015 at 8:30 a.m. Eastern Daylight Time

DANBURY, CT--(Marketwired - March 16, 2015) - Biodel Inc. (NASDAQ: BIOD) announced positive preliminary results from Study 6-101, a Phase 1 clinical trial comparing Biodel's lyophilized glucagon formulation BIOD-961, designed for use in a proprietary Glucagon Emergency Management (GEM) auto-reconstitution device, to Eli Lilly's Glucagon Emergency Rescue Kit and Novo Nordisk's GlucaGen® HypoKit™, which are marketed for the treatment of severe hypoglycemia. Study 6-101 was a randomized, single-center, double blind, six-period cross over study in 15 healthy volunteers who received each glucagon administered subcutaneously (SC) and intramuscularly (IM) in a randomized treatment sequence. The objectives of the study were to compare the pharmacokinetic (PK) profiles, the pharmacodynamic (PD, glucose) responses, and the PK/PD relationships of IM and SC dosing, as well as to assess safety profiles of the three test glucagons. 

Data Highlights

  • Overall, PK and PD (glucose response) profiles among all three glucagon formulations were statistically indistinguishable.
  • Although this study was designed as an exploratory comparison of PK and PD profiles, standard regulatory criteria for PK and PD bioequivalence were satisfied when comparing BIOD-961 to Eli Lilly's Glucagon Emergency Rescue Kit and Novo Nordisk's GlucaGen® HypoKit™.
  • As expected, nausea was the most common adverse event for all glucagon formulations. The incidence of adverse events was similar among treatments.

Biodel formulated BIOD-961 for use in a user-friendly injection device, referred to as the Glucagon Emergency Management (GEM) system. The GEM device is a customized version of an auto-reconstitution syringe developed by Unilife Corporation. The device is specifically designed to address and expand an underserved market currently wrestling with cumbersome glucagon kits that are especially difficult to use and operate during an emergency for the treatment of severe hypoglycemia.

Dr. Alan Krasner, chief medical officer of Biodel, stated: "We are very pleased that in this exploratory trial BIOD-961 shows the ability to meet pharmacokinetic and pharmacodynamic criteria for bioequivalence to a marketed glucagon formulation. The FDA requires PK and PD bioequivalence as co-primary objectives of our pivotal trial for approval of this product. We look forward to sharing these data with the FDA and discussing the components of the remaining development program, including the design of the pivotal bioequivalence trial." 

Dr. Errol De Souza, president and chief executive officer of Biodel, stated: "The results of this study exceeded expectations. This is the first glucagon formulation in development for the treatment of severe hypoglycemia which has demonstrated comparable pharmacokinetic and pharmacodynamic profiles to marketed glucagon formulations. In addition to the pivotal clinical trial, a human factors study is planned for the first half 2015 to compare the usability of the GEM device to the existing manually reconstituted commercial glucagon kits in the hands of representative caregivers, with the final pivotal human factors study expected to be completed by the end of 2015. We plan to request an end-of-Phase 2 meeting with the FDA in the second calendar quarter of 2015 and submit the NDA in mid-2016."

Study Design

Study 6-101 was a Phase 1 randomized, single-center, double blind, six-period cross over study designed to evaluate the PK and PD profiles of BIOD-961 compared to marketed glucagon formulations manufactured by Eli Lilly and Novo Nordisk. BIOD-961 is a lyophilized glucagon formulation designed for use in the GEM auto-reconstitution device. On six separate dosing days, each subject received 1 mg of one of the test glucagons delivered either SC or IM. Fifteen normal, healthy subjects were randomized into the study and ten completed all dosings. The objectives of the study were to compare the PK profiles, the PD (glucose) responses, and the PK/PD relationships of IM and SC dosing, as well as to assess safety profiles of the three test glucagons. These data will facilitate selection of an appropriate marketed glucagon to use as a comparator in the planned pivotal study, in which the primary efficacy endpoint for approval is to demonstrate PK and PD bioequivalence of BIOD-961 to one of the marketed comparators.

About Glucagon Emergency Management (GEM) Device for the Treatment of Severe Hypoglycemia

Biodel's Glucagon Emergency Management (GEM) system is a lyophilized glucagon formulation provided in a proprietary auto-reconstitution device intended for the rescue treatment of patients with severe hypoglycemia. GEM is expected to be available in separate presentations for the delivery of pediatric (0.5 mg) and adult (1.0 mg) dosages of glucagon. The GEM device provides automatic needle retraction after dose delivery. 

There is currently an unmet medical need for a more user-friendly glucagon emergency injection device since the complexity of existing kits increases caregiver training requirements, the likelihood of dosing errors (especially dosing only with diluent) and the time required to deliver the rescue therapy. It is believed that these factors lead to relatively low prescription, fill, refill and usage rates of existing glucagon emergency kits. The annual U.S. glucagon market for the treatment of severe hypoglycemia is approximately $160 million.

The GEM device has been designed to require little to no training for use and is intended to be a more user-friendly glucagon presentation compared to emergency kits currently marketed by Eli Lilly and Novo Nordisk. The automatic reconstitution of the glucagon formulation eliminates the possibility of dosing only with diluent. The automatic needle retraction after dose delivery reduces the risk of accidental needle stick injuries. Dating and storage of the GEM device is anticipated to be comparable to existing glucagon kits.
