~ EVOMELA^® (melphalan for injection) Fourth Quarter 2021 Revenue Continues Strong Upward Trend, exceeding guidance ~

ROCKVILLE, Md. and BEIJING, March 28, 2022 /PRNewswire/ -- CASI Pharmaceuticals, Inc. (Nasdaq: CASI), a U.S. biopharmaceutical company focused on developing and commercializing innovative therapeutics and pharmaceutical products, today reported financial results for the year ended December 31, 2021, and provided an update on key highlights for 2022. 

Wei-Wu He, Ph.D., CASI's Chairman, and Chief Executive Officer, commented, "We are pleased to report $9.12 million in EVOMELA^® revenues for the fourth quarter of 2021. We have achieved our goal for full-year 2021 revenue growth to reach 100% growth. Through the efforts of the global CASI team and our commercial group of more than 100 hematology sales and medical marketing specialists in China, we have built a strong foundation for our commercial franchise. We plan to continue building our commercial franchise throughout 2022 and beyond."

Dr. He continued, "As we assemble a world-class pipeline of assets and drive existing development forward, we continue to execute on several key milestones across our broad portfolio. In 2021, our team prepared for the anticipated China NDA filing of the CD19 CAR-T program, which we currently expect to be in the second half of 2022. We anticipate that EVOMELA will continue to be the core of our commercial operations in the quarters ahead. During 2022, we also expect the start of the BI-1206 Phase I trial in China, receipt of CTA approval from NMPA for CB-5339, and the continued progression of the Phase I study of CID-103."

Key Highlights for 2022

EVOMELA^® (melphalan for injection)

Prior to EVOMELA's entry into the Chinese market, an average of 800 stem cell transplants per year were conducted in the multiple myeloma treatment setting. Following EVOMELA's launch in August 2019, CASI worked closely with key opinion leaders to drive market awareness and expedite EVOMELA adoption in the Chinese market. In 2021, EVOMELA was used in the treatment of nearly 6,000 patients in China. CASI continues to pursue a similar strategy with respect to marketing efforts and physician visits to further the adoption of stem cell transplantation as a standard of care in the multiple myeloma treatment setting and will continue working to address the persistent high unmet need in this patient population.

CNCT19 (CD19 CAR-T)

Our partner, Juventas Cell Therapy Ltd (Juventas), continues the development of CNCT19, an autologous CD19 CAR-T investigative product for which CASI has co-commercial and profit-sharing rights. CNCT19 is being developed as a potential treatment for patients with hematological malignancies which express CD19 including, B-cell acute lymphoblastic leukemia (B-ALL) and B-cell non-Hodgkin lymphoma (B-NHL). The Phase 2 B-ALL and B-NHL registration studies are both currently enrolling. In December 2020, CNCT19 received Breakthrough Therapy Designation based on initial data from the ongoing single-arm, open-label, non-randomized, dose-escalation, Phase 1 study designed to determine the safety and efficacy of CNCT19 in B-ALL. Earlier this year, the U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation (ODD) to Juventas, for CNCT19, for the treatment of patients with Acute Lymphoblastic Leukemia (ALL). Currently, there are no CD-19 CAR-T therapies marketed in China based on domestically developed CAR-T technology. CASI intends for CNCT19 to be locally developed and manufactured to be more affordable and widely accessible to patients.

BI-1206 (Anti-FcyRIIB antibody)

Along with our partner, BioInvent, we continue to progress the development and regulatory framework for BI-1206 in China. The National Medical Products Administration (NMPA) granted BI-1206 Clinical Trial Application (CTA) approval in December 2021. Ethics committee approval from a leading investigational site was granted in January 2022. BI-1206 is currently being investigated outside of China in two Phase 1/2 trials. One is evaluating the BI-1206 combination with rituximab for the treatment of non-Hodgkin lymphoma (NHL), which includes patients with follicular lymphoma (FL), mantle cell lymphoma (MCL), and marginal zone lymphoma (MZL) who have relapsed or are refractory to rituximab. A second Phase 1/2 trial is investigating BI-1206 in combination with anti-PD1 therapy Keytruda^® (pembrolizumab) in solid tumors. Earlier this year, the U.S. FDA granted Orphan Drug Designation, for BI-1206, for the treatment of follicular lymphoma, the most common form of slow-growing non-Hodgkin lymphoma.

CB-5339 (VCP/p97 inhibitor)

CB-5339 CTA application for the multiple myeloma indication is in preparation after receiving an acceptance letter for the CB-5339 IND package from the China Center of Drug Evaluation. Cleave Therapeutics is responsible for the ex-China development of CB-5339, an oral second-generation, small molecule VCP/p97 inhibitor, and is evaluating the molecule in a Phase 1 clinical trial in patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS).

CID-103 (Anti-CD38 Mab)

CID-103 is a fully human IgG1 anti-CD38 monoclonal antibody recognizing a unique epitope that has demonstrated encouraging preclinical efficacy and safety profile compared to other anti-CD38 monoclonal antibodies. CASI maintains exclusive global rights and is developing CID-103 for the treatment of patients with multiple myeloma. The Phase 1 dose escalation and expansion study of CID-103 in patients with previously treated relapsed or refractory multiple myeloma is ongoing in France and the UK.

Full-Year 2021 Financial Highlights

• Revenues consist primarily of product sales of EVOMELA. Revenue was $30.0 million for the year ended December 31, 2021, compared to $15.0 million for the year ended December 31, 2020.
• Costs of revenues were $12.6 million for the year ended December 31, 2021, compared to $9.5 million for the year ended December 31, 2020, which includes royalty payment of $5.9 million and $3.0 million for the same period. Costs of revenues excluding royalty were approximately $6.6 million and $6.6 million for the year ended December 31, 2021, and December 31, 2020 respectively. Costs of revenues, excluding royalty as a percentage of revenues, decreased significantly for the year ended December 31, 2021, compared to 2020; and, secondarily, such decrease in costs of revenues, excluding royalty as a percentage of revenues, resulted from a decrease in the unit cost of inventories of EVOMELA.

• Selling and marketing expenses for the year ended December 31, 2021, were $14.7 million, compared with $7.8 million for the year ended December 31, 2020. The increase in selling and marketing expenses primarily was due to the expansion of the sales team in China in 2021.
• Net loss for the year ended December 31, 2021, was $35.8 million compared to $47.5 million for the year ended December 31, 2020, primarily due to the increase in revenues.
