The American Academy of Dermatology is the largest, most influential, and representative dermatology group in the United States. The poster features preliminary findings on disease control from a phase 1 study, evaluating the safety and efficacy of Silmitasertib in patients with advanced BCC.

"We are very pleased with the preliminary results of this phase 1 study and we look forward to the final results at the conclusion of the study," said Dr. John Soong, Chief Medical Officer of Senhwa Biosciences.

BCC is the most common type of skin cancer. Most basal cell carcinomas can be surgically removed; however, for unresectable tumors there are two approved targeted drugs and both are characterized as smoothened inhibitors (SMOi). SMOi target the Hedgehog (Hh) pathway and have been approved for the treatment of patients with locally advanced BCC (laBCC) or metastatic BCC (mBCC).

Unfortunately, drug resistance to SMOi is common but targeting the signaling cascade downstream of SMOi could avoid this issue. Casein Kinase 2 (CK2) affects the terminal component of the Hh signaling pathway by promoting GLI-1 stability and GLI-1’s interaction with target genes. Given the interplay between CK2 and GLI-1 and the importance of Hh signaling activation, Senhwa’s Silmitasertib (CX-4945), a potent CK2 inhibitor, may provide benefits for BCC patients with SMOi resistant cancers.

About Silmitasertib

Silmitasertib is a first-in-class small molecule drug that targets the CK2 pathway and acts as a CK2-inhibitor. Clinical studies thus far have shown Silmitasertib to be safe and well-tolerated in humans and is easily administered due to its oral formulation. Silmitasertib is currently under development in several oncology programs in adults and children with recurrent/advanced or metastatic cancer. To date, three Phase I trials and one Phase II trial of Silmitasertib in cancer patients have been completed; currently, there are two ongoing Phase I/II studies of Silmitasertib.

The US FDA has granted Silmitasertib key drug designations: Orphan Drug Designation for the treatment of Cholangiocarcinoma in December 2016, Rare Pediatric Disease Designation and Orphan Drug Designation for the treatment of Medulloblastoma in July 2020 and December 2021, respectively. Fast Track Designation was granted in August 2021 for the treatment of recurrent Sonic Hedgehog driven Medulloblastoma.

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.
Research and development expenses for the year ended December 31, 2021, were $14.4 million, compared with $11.5 million for the year ended December 31, 2020.
General and administrative expenses for the year ended December 31, 2021, were $23.8 million, compared with $19.7 million for the year ended December 31, 2020.
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.
As of December 31, 2021, CASI had cash and cash equivalents of $38.7 million compared to $57.1 million as of December 31, 2020.

Avera has a long-standing history of leading the way in precision oncology with patients’ tumors being genetically sequenced to guide individualized cancer care. Theralink, with its patented protein and phosphoprotein biomarker platform and lab developed test, is the only commercially available assay for clinical use that measures the tumor cell levels of activated proteins, which are the primary targets of most FDA-approved therapies and biopharmaceutical investigational drugs.

Theralink will provide key patient-specific information about which drug targets are activated and "in use" in each patient tumor sample. This information, coupled with the genomics findings, will provide a comprehensive molecular profile for all Avera oncology patients by way of a multiomic report used for physician treatment decisions.

"Avera has been a cancer care leader in our region for many years. Avera Cancer Institute is focused on actionable insights for our physicians and patients to make treatment decisions that are personalized," said Casey Williams, Chief Scientific Officer and Executive Director of Cancer Research. "We understand the role this innovative approach plays in generating better health outcomes for our patients, and Theralink will play a key role in that process."

"We believe that the Theralink protein/phosphoprotein data, combined with the next generation sequencing data, may give Avera Cancer Institute the most cutting edge and best precision oncology data in the world, potentially creating a step change in cancer care," said Mick Ruxin, M.D., President & CEO of Theralink. He went on to say, "It is gratifying to know that a large, prestigious, midwest cancer program, Avera Health, has realized the significant potential value of our Theralink assay for their cancer patients." Dr. Ruxin continued, "We expect great results from working with Avera and their patients in our goal to decrease the morbidity and mortality of cancer patients."

As part of this collaboration, Avera will assist Theralink Technologies in validating new clinical assays for additional tumors (such as GYN, Head and Neck, GI, Lung, Kidney, Liver and Prostate) through retrospective case analysis and population-based data. This may bring new capability and insights to precision oncology care and allow for the Theralink assay to become a pan-tumor assay.

"We’re excited for GTB-3650’s prospects in the new year as we advance the Company’s second-generation Tri-specific NK cell engager (TriKE) technology into an IND-enabling study. The development of GTB-3650, our lead-asset second generation nanobody TriKE has been significantly de-risked, propelled by GTB-3550 predecessor data published in 2021 including: positive first-in-human Phase 1 data; and in-vivo animal model data, conducted in combination with a bispecific killer cell engager asset," said Michael Breen, Executive Chairman and Interim Chief Executive Officer. "Our optimism continues to rise as these proof-of-concept data demonstrate a well-tolerated safety profile and strong NK cell activation against a broad range of tumors. In total, the Company’s TriKE nanobody platform, a rich platform technology, has demonstrated broad utility. We are confident in our ability to develop these assets as a monotherapy, as a combination therapy with conventional chemotherapy, or in combination with other potential joint commercialization technologies."

Quarterly Highlights
The Company presented pre-clinical TriKE data in an oral poster-presentation both virtually and in-person at ESMO (Free ESMO Whitepaper) Targeted Anticancer Therapies (TAT) Congress, March 7–8, 2022.
The pre-clinical evidence suggests, despite the difference in circulating immune cells of Stage IVB NSCLC patients, mesothelin-targeted TriKE can work alongside current standard of care and provide benefit even in the hypoxic environment of a solid tumor.
Dr. Jeffrey Miller, GT Biopharma consultant Chief Scientific Officer, also participated in an oral poster-presentation session at the European Society for Medical Oncology Immuno-Oncology (ESMO IO) Congress, December 8–11, 2021.
The presentation highlighted the broad activity of GTB-5550, which harbors wild-type IL-15 in combination with TriKE against B7-H3-expressing tumors.
Upcoming Conference Participation
GT Biopharma will participate in poster-presentation sessions at the following upcoming medical conferences:
EBMT Abstract AS_EBMT-2022-00508, "A Tri-specific Killer Engager (TriKE) against B7-H3 enhances NK cell mediated killing of multiple myeloma"
AACR Abstract 3435, "GTB-5550 (cam16-IL15-camB7H3) Tri-specific Killer Engager (TriKE) drives natural killer cell activation and antibody dependent cellular cytotoxicity against head and neck squamous cell carcinomas"

About Camelid Antibodies
Camelid antibodies are single domain antibodies (sdAbs) from the Camelidae family of mammals that include llamas, camels, and alpacas. These animals produce two main types of antibodies. One type of antibody camelids produce is the conventional antibody that is made up of two heavy chains and two light chains. They also produce another type of antibody that is made up of only two heavy chains and no light chain. This is known as heavy chain IgG (hcIgG). While these antibodies do not contain the CH1 region, they retain an antigen binding domain called the VHH region. VHH antibodies, also known as single domain antibodies, contain only the VHH region from the camelid antibody. Camelid antibodies have key characteristics, which include high affinity and specificity (equivalent to conventional antibodies), high thermostability, good solubility and strictly monomeric behavior, small size, relatively low production cost, ease of genetic engineering, format flexibility or modularity, low immunogenicity, and a higher penetration rate into tissues.
