CASI Pharmaceuticals Announces Receipt Of Final Minutes From FDA Meeting Regarding Clinical And Regulatory Path Of ENMD-2076 For The Treatment Of Patients With Fibrolamellar Carcinoma (FLC)

ROCKVILLE, Md., Feb. 9, 2015 /PRNewswire/ -- CASI Pharmaceuticals, Inc. (Nasdaq: CASI), a biopharmaceutical company dedicated to the acquisition, development and commercialization of innovative therapeutics addressing cancer and other unmet medical needs for the global market with a commercial focus on China, is pleased to announce that it has received formal meeting minutes from the U.S. Food and Drug Administration (FDA) regarding the clinical and regulatory path leading to market approval of ENMD-2076 for the treatment of Fibrolamellar Carcinoma (FLC).  The meeting minutes stem from a recent informative meeting between CASI and the FDA.

"We are strongly encouraged by the FDA's feedback and appreciate their guidance and support of our development program," commented Ken K. Ren, Ph.D., CASI's Chief Executive Officer. "Based on our meeting, we believe the FDA has provided us with a clear direction for the clinical and regulatory path forward, particularly regarding the design of our clinical trial, which may support a New Drug Application (NDA) of ENMD-2076 as the first line therapy for FLC."

Dr. Ren commented further, "As confirmed by the FDA, below are the key elements of our clinical and regulatory path:

• We plan to conduct a single arm trial to evaluate the overall response rate (ORR) of ENMD-2076 in FLC patients as the primary endpoint.
• The trial will be conducted as a Simon 2-stage study with interim futility analysis released after 16 patients reach a clinical endpoint.  Futility would be declared if none of the patients experience a response and would result in the termination of the study. 
• If, however, one or more patients experience a response according to the RECIST 1.1 criteria, the study would continue with additional patients.  At that time, we would expect to meet with the FDA to discuss what tumor response criteria would be considered reasonably likely to provide clinical benefit and support an accelerated approval based on the surrogate endpoint of tumor response.
• Assuming that the results of the proposed study show that ENMD-2076 improves overall tumor response, CASI would expect to propose a confirmatory clinical trial and, in parallel, submit an NDA under subpart H for accelerated approval of new drugs for serious or life-threatening illnesses based on overall tumor response rates.
• CASI will submit to the FDA a request for Breakthrough Therapy designation whenever clinical data meets the appropriate criteria."

"While fulfilling the FDA's other regulatory requirements, including a food effect study of ENMD-2076 in healthy human subjects, we intend to move forward and are working with our dedicated investigators and the FLC patient community to initiate the trial as soon as possible and will update our study protocol at www.clinicaltrials.gov once a final version of the protocol is available.  We have received orphan drug designation for hepatocellular carcinoma, from the FDA in the U.S. and intend to file for orphan drug designation for FLC in the EU."
