CGEM Cullinan Therapeutics Inc

Cullinan Therapeutics, Inc. (Nasdaq: CGEM; “Cullinan”), a biopharmaceutical company focused on developing modality-agnostic targeted therapies, today reported recent and anticipated business highlights and announced its financial results for the second quarter ended June 30, 2024.

“We are keenly focused on executing on the strategic plans we made during the first half of 2024, including our expansion into autoimmune diseases and continued advancement of our oncology pipeline, each facilitated by our recent oversubscribed financing,” said Nadim Ahmed, Chief Executive Officer of Cullinan Therapeutics. “During the second half of 2024, we will advance CLN-978 toward a first global clinical study in systemic lupus erythematosus (SLE) and remain on track to file an investigational new drug (IND) application in the third quarter of this year. We are committed to exploring the broad potential of CLN-978 across autoimmune diseases and will pursue rheumatoid arthritis (RA) as our next indication, where there is both significant unmet patient need and clinical validation for CD19 T cell engagers. We are excited to collaborate with FAU Erlangen-Nuremberg and Università Cattolica del Sacro Cuore, Rome to conduct a clinical trial of CLN-978 in patients with RA. Both are pioneering centers of excellence in the field of T cell redirecting therapies for autoimmune diseases and the first to demonstrate the potential of a CD19 T cell engager in RA. Finally, to focus our resources on our most promising programs, we will discontinue development of CLN-418 based on initial clinical observations.”

“At FAU, we are excited about the prospect of a clinical trial of a new T cell engager in RA,” said Dr. Ricardo Grieshaber-Bouyer, M.D., Ph.D., Professor of Clinical Systems Immunology and Head of the Clinical Trials Unit at FAU Erlangen-Nuremberg, “There is a significant unmet need in treating patients with RA who are refractory to currently available treatments. Our team at Erlangen has already demonstrated that a T cell engager targeting CD19 has potential to dramatically alter the course of disease in these patients, and we look forward to furthering our initial groundbreaking work in this area with CLN-978, which could potentially offer significant benefit to patients with convenient, off-the-shelf subcutaneous administration and a favorable safety profile.”

Portfolio Highlights

     Immunology

• CLN-978 (CD19xCD3 T cell engager): Systemic lupus erythematosus and rheumatoid arthritis
  • Cullinan remains on-track to submit an IND application for the global SLE study to the U.S. Food and Drug Administration in the third quarter of 2024.
  • The company plans to explore CLN-978 in rheumatoid arthritis as its second autoimmune indication and will collaborate with FAU Erlangen-Nuremberg in Germany and Università Cattolica del Sacro Cuore, Rome to conduct a company sponsored clinical trial in that indication.

     Oncology

• CLN-619 (Anti-MICA/MICB monoclonal antibody): Solid tumors and hematological malignancies
  • Cullinan presented initial data from the combination dose escalation module, as well as an update on the monotherapy dose escalation, during a poster session at the 2024 ASCO Annual Meeting on June 1, 2024.
  • The combination therapy data demonstrated objective responses in patients with non-small cell lung cancer (NSCLC) with oncogenic mutations, which is typically unresponsive to checkpoint inhibitors. The monotherapy data demonstrated durability of clinical benefit with longer follow-up.
  • Based on the observed data, the company announced additional disease expansion cohorts for both monotherapy and in combination with pembrolizumab in NSCLC as well as in combination with chemotherapy in platinum resistant ovarian cancer.
  • Cullinan remains on track to report initial data from disease-specific dose expansion cohorts in endometrial and cervical cancers in the first half of 2025.
• Zipalertinib (EGFR ex20ins inhibitor), collaboration with Taiho Oncology: EGFR ex20ins NSCLC
  • In June, Cullinan announced positive initial data from the pivotal Phase 2b portion of the REZILIENT1 study in patients with EGFR ex20ins NSCLC who have progressed after prior chemotherapy as well as the exon 20 targeted therapy amivantamab. The results in this emerging patient population showed similar efficacy and safety for zipalertinib as seen in patients progressing after prior chemotherapy alone.
  • An update to these initial REZILIENT1 results in patients with EGFR ex20ins NSCLC who have progressed after both prior chemotherapy and amivantamab will be presented in a mini oral presentation at the European Society for Medical Oncology (ESMO) meeting in September.
  • Cullinan expects to complete enrollment in the pivotal Phase 2b portion of REZILIENT1 by year-end 2024.
• CLN-049 (FLT3xCD3 T cell-engaging bispecific antibody): AML and MDS
  • Following a review of the data from the Phase 1 study of CLN-049, Cullinan is reporting that in the ongoing Phase 1 study in patients with relapsed/refractory AML and MDS, dose-limiting injection site reactions were observed during dose escalation with subcutaneous administration. Based on these findings, together with observations of preliminary clinical activity, dose escalation is now continuing in the study with IV administration.
• CLN-617 (IL-2 and IL-12 cytokine fusion protein): Solid tumors
  • Enrollment continues in the ongoing Phase 1 study in patients with advanced solid tumors.
• CLN-418 (B7H4x4-1BB bispecific immune activator): Solid tumors
  • Following a review of the data from the Phase 1 study of CLN-418, Cullinan plans to discontinue development and has notified Harbour BioMed of termination of the license agreement. In connection with the termination, Cullinan will return development and commercial rights to Harbour BioMed.

Corporate Updates

• In April, the Company completed an oversubscribed private placement of common stock grossing $280 million. The financing included new and existing leading life sciences institutional investors.
• In August, the Company added experienced biotech executive Mary Thistle to its Board of Directors. Ms. Thistle brings thirty years of operational and business development expertise, including experience in autoimmune diseases, that will add significant value to Cullinan’s growth strategy.
