CASI PHARMACEUTICALS ANNOUNCES

SECOND QUARTER 2024 BUSINESS AND FINANCIAL RESULTS

BEIJING, China (August 16, 2024) CASI Pharmaceuticals, Inc. (Nasdaq: CASI) (“CASI” or the “Company”), a Cayman incorporated biopharmaceutical company specializing in the development and commercialization of innovative therapeutics and pharmaceutical products, today reported business updates and financial results for the three months ended June 30, 2024.

“The second quarter of 2024 was a period of significant progress for CASI as we shifted our Company’s strategy to the development of therapeutics for organ transplant rejection and autoimmune disease,” said Dr. Wei-Wu He, Chairman and CEO of CASI Pharmaceuticals. “The keystone of our strategic pivot is CID-103, an anti-CD38 antibody that we believe has potential for therapeutic use across multiple areas of unmet need, including antibody-mediated rejection (AMR) and idiopathic thrombocytopenia purpura (ITP). Ultimately, we believe CID-103 has widespread therapeutic use in many immune-mediated diseases. We are structuring our resources according to this expectation and will aim to advance our anti-CD38 programs at a brisk pace.”

Dr. He continued: “For both AMR and ITP, we are anticipating clinical study initiation on an efficient timeline. We are pleased that the U.S. FDA recently cleared our Investigational New Drug (IND) application for CID-103 for the treatment of adults with ITP, and we expect to initiate our planned Phase 1 study by year end. We anticipate that we will submit an IND for CID-103 in AMR in the fourth quarter of this year. We are especially pleased to have recently announced a $15 million private placement financing by Venrock Healthcare Capital Partners, Foresite Capital, and Panacea Venture in support of our strategy and its execution.”

CASI’s Board of Directors has formed a special committee to evaluate Dr. He’s proposal letter dated June 21, 2024, to acquire the entire business operations of the Company in China, including all license-in, distribution and related rights in Asia (excluding Japan), for an aggregate purchase price of $40.0 million. The offer price includes assumption of up to $20.0 million of the Company’s debt.
