CASI Pharmaceuticals Reports Second Quarter 2014 Financial Results

ROCKVILLE, Md., Aug. 14, 2014 - CASI Pharmaceuticals, Inc. (CASI) , a clinical-stage pharmaceutical company developing therapeutics for the treatment of cancer and other diseases, today reported financial results for the three and six months ended June 30, 2014.

CASI reported a net loss for the second quarter of 2014 of ($1.6 million), or ($0.06) per share. This compares with a net loss of ($1.9 million), or ($0.07) per share, for the same period last year. For the first six months of 2014 the net loss was ($3.1 million), or ($0.11) per share, compared with a net loss of ($3.0 million), or ($0.12) per share, for the first six months of 2013.

As of June 30, 2014, CASI had cash and cash equivalents of approximately $13.1 million.

Sara B. Capitelli, CASI’s Vice President, Finance, commented on the second quarter results, “Our second quarter 2014 financial results were in line with expectations. Research and development expenses decreased compared with the previous year due to lower non-cash stock-based compensation expense of $0.2 million, partially offset by increases in costs associated with the manufacturing and clinical development of ENMD-2076 in the U.S. and our research and development operations in China. General and administrative expenses for the second quarter of 2014 decreased compared with the previous year, reflecting lower non-cash stock-based compensation expense of $0.2 million, partially offset by an increase in corporate business development activities. As we continue to execute our clinical development plan, we expect operating expenses to increase in 2014.”

Ken K. Ren, Ph.D., CASI’s Chief Executive Officer, stated, “We are pleased with our financial position and will continue to manage expenditures as we advance the development of ENMD-2076.”

Commenting on the Company’s most recent milestones, Dr. Ren added, “Subsequent to the close of the second quarter the Company was granted Orphan Drug designation by the U.S. Food and Drug Administration (FDA) for ENMD-2076 in hepatocellular carcinoma and was also granted approval from China’s Food and Drug Administration (CFDA) to start a Phase II trial of ENMD-2076 in Chinese patients with triple-negative breast cancer (TNBC). CFDA’s approval will allow CASI to fully embrace our U.S./China business strategy and we look forward to starting a TNBC trial in China. The data from these patients will also be used in support of our U.S. regulatory strategy.”

About ENMD-2076

ENMD-2076 is an orally-active, Aurora A/angiogenic kinase inhibitor with a unique kinase selectivity profile and multiple mechanisms of action. ENMD-2076 has been shown to inhibit a distinct profile of angiogenic tyrosine kinase targets in addition to the Aurora A kinase. Aurora kinases are key regulators of mitosis (cell division), and are often over-expressed in human cancers. ENMD-2076 also targets the VEGFR, Flt-3 and FGFR3 kinases, which have been shown to play important roles in the pathology of several cancers. ENMD-2076 has shown promising activity in Phase I clinical trials in solid tumor cancers including ovarian, breast, liver, renal and sarcoma, as well as in leukemia and multiple myeloma. CASI is completing a Phase II trial of ENMD-2076 in ovarian cancer. In addition, CASI is conducting a dual-institutional Phase II study of ENMD-2076 in triple-negative breast cancer, a Phase II study in advanced/metastatic soft tissue sarcoma and a Phase II ovarian clear cell carcinomas. ENMD-2076 has received orphan drug designation from the U.S. FDA for the treatment of ovarian cancer, multiple myeloma, acute myeloid leukemia, and hepatocellular carcinoma.
