Genmab's HuMax-EGFr Awarded Fast Track Status From FDACOPENHAGEN, Denmark, Jan. 3 (HSMN NewsFeed) -- Genmab A/S (CSE: GEN ) announced today that HuMax-EGFr has been designated a Fast Track Product by the US Food and Drug Administration (FDA). This designation covers patients with head and neck cancer who have previously failed standard therapies. Genmab presented positive results from the Phase I/II study of HuMax-EGFr in May 2005.
Fast Track Product status allows the FDA to facilitate the development and expedite the review of a drug if it is intended for the treatment of a serious or life-threatening condition, and if it demonstrates the potential to address unmet medical needs for such a condition.
This fast track designation gives Genmab the opportunity to submit a Biologics License Application (BLA) in sequential sections, and have these sections reviewed as they are submitted, thus saving development time. A BLA is the biologic products' equivalent to a New Drug Application and is the final stage before a drug is approved for the market by the FDA. Fast track status also opens the possibility for receiving a priority review or accelerated approval of the BLA where the review time would be halved to just 6 months.
"We are very pleased that HuMax-EGFr has been designated a Fast Track product and is now poised to move forward to pivotal studies which we hope to begin this year," said Lisa N. Drakeman, Ph.D., Chief Executive Officer of Genmab.
HuMax-EGFr is a fully human, high-affinity antibody targeted at the Epidermal Growth Factor receptor (EGFr). EGFr is a receptor molecule found on the surface of many cancer cells. Activation of EGFr by the appropriate growth factor molecule promotes the growth of tumor cells.
In September 2003, Genmab initiated an open label Phase I/II clinical trial using HuMax-EGFr to treat patients suffering from confirmed recurrent or metastatic squamous cell carcinoma of the head and neck who had previously failed standard therapies. Twenty-four patients were included in the initial trial, which was extended in October 2004 to include three additional patients. Patients were divided into six dose groups and received IV infusions of HuMax-EGFr at doses of 0.15, 0.5, 1, 2, 4, or 8 mg/kg. Twenty patients received all five infusions. The primary and secondary endpoints of the study were safety and efficacy of HuMax-EGFr.
Clinical and metabolic response was demonstrated by two types of scanning. Assessed by FDG-PET, which visualizes tumor metabolism, 7 of 18 evaluable patients achieved partial metabolic response (PMR) and 4 had stable metabolic disease (SMD) one week after their fifth and last infusion. In the two highest dose groups, 9 out of 11 patients obtained PMR or SMD.
Clinical response evaluated by computerized tomography (CT scan) supported the positive FDG-PET results. Two of 19 evaluable patients achieved partial response (PR) and 9 patients had stable disease (SD) according to RECIST criteria. The partial response was maintained at week 12 by one of the two patients. The other patient's disease progressed five weeks after the last treatment, but following additional HuMax-EGFr treatment at 8 mg/kg on a compassionate use basis, the patient re-obtained the partial response. In the two highest dose groups 7 out of 10 patients obtained PR or SD.
Results from the trial indicate that HuMax-EGFr is well tolerated by head and neck cancer patients. Furthermore, no patients experienced Dose Limiting Toxicity when treated with the highest dose of 8 mg/kg. The most frequent adverse event was acneiform rash demonstrating biological activity of HuMax- EGFr in 56% of the patients. The occurrence increased with dose, with 10 of 11 patients in the 4 and 8 mg/kg dose groups experiencing rash. Other adverse events included rigors, fatigue, pyrexia, nausea, flushing and increased sweating. One case of grade 3 rash was reported. One patient reported a serious adverse event considered related to treatment with HuMax-EGFr, grade 2 pyrexia, which developed during the first infusion. The patient recovered and completed the study.
