CAMBRIDGE, Mass., March 17, 2022 (GLOBE NEWSWIRE) — Cullinan Oncology, Inc. (Nasdaq: CGEM), a biopharmaceutical company focused on developing a diversified pipeline of targeted therapies for patients with cancer, today reported on recent and upcoming business highlights and announced its financial results for the fourth quarter and full year ended December 31, 2021.

“Cullinan Oncology is dedicated to developing new standards of care in cancer therapy and we made considerable progress toward this goal in 2021, including advancing additional programs into the clinic, adding new assets to our pipeline, and deepening our oncology expertise with new additions to our board and leadership team,” said Nadim Ahmed, Chief Executive Officer of Cullinan Oncology. “In the fourth quarter of 2021, we reported compelling data from the ongoing Phase 1/2a trial of our lead program, CLN-081. We were also pleased to announce in January of this year that the FDA granted CLN-081 Breakthrough Therapy Designation, a distinction that further supports its differentiated clinical profile in NSCLC patients with EGFR exon 20 insertion mutations. We look forward to providing a regulatory update in the coming weeks.”

Mr. Ahmed continued, “Additionally, we initiated clinical trials for two other differentiated oncology programs, CLN-619 and CLN-049, while further expanding our pipeline with the addition of an HPK1 degrader collaboration with the Icahn School of Medicine at Mount Sinai. Finally, we expanded our late-stage oncology expertise and leadership with the recent appointments of Dr. Jeff Jones as Chief Medical Officer and Dr. Anne-Marie Martin as an independent director. Finishing the year with over $430 million of cash and investments, we remain well positioned to continue advancing our broad pipeline of first- and/or best-in-class oncology molecules as we work toward our mission of developing new therapeutic solutions for people living with cancer.”

Portfolio Highlights

• CLN-081 (Pearl): During the fourth quarter of 2021, Cullinan reported updated Phase 1/2a data for CLN-081 in NSCLC patients harboring epidermal growth factor (EGFR) exon 20 insertion mutations who have previously received platinum-based systemic chemotherapy. The update included safety and efficacy data from 73 patients treated across all five dose levels (30 – 150mg BID). At the 100mg BID dose level, 35 of 36 (97%) response evaluable patients achieved a best response of partial response or stable disease, with 14 (39%) patients achieving a confirmed partial response. Among patients enrolled in the initial Phase 1 cohort at 100mg BID (n=13), the estimated median duration of response was greater than 15 months and the estimated median progression free survival was 12 months. In January 2022, Cullinan announced that CLN-081 received Breakthrough Therapy Designation. Cullinan will provide a regulatory update on CLN-081 on March 28th, 2022.
• CLN-049 (Florentine): CLN-049 is a FLT3/CD3-bispecific T cell-engaging antibody in an IgG format for the treatment of acute myeloid leukemia (AML). CLN-049 targets the extracellular domain of FLT3, regardless of mutant or wild type-based expression. In December 2021, patient dosing was initiated in a first-in-human clinical trial evaluating CLN-049 in patients with relapsed/refractory AML. A more extensive preclinical characterization of CLN-049 has been published in the Journal for Immunotherapy of Cancer (JITC), titled, “A Novel IgG-based FLT3xCD3 Bispecific Antibody for the Treatment of AML and B-ALL.” Initial clinical data are expected by mid-2023.
• CLN-619 (MICA): CLN-619 is a first-in-class monoclonal antibody that stabilizes MICA/MICB on the tumor cell surface to promote an antitumor response via activation of both natural killer (NK) cells and certain T cells, with broad therapeutic potential across multiple cancer indications. In December 2021, patient dosing was initiated in a first-in-human clinical trial evaluating CLN-619 in patients with advanced tumors. The trial design includes parallel evaluation of CLN-619 as a monotherapy and in combination with checkpoint inhibitor therapy in separate modules. Initial clinical data are expected by mid-2023.
• Preclinical Portfolio: Continued advancement of five additional oncology programs with the following highlights:
  • Preclinical data across five distinct programs will be presented at the American Association for Cancer Research (AACR) 2022 Annual Meeting, including CLN-049, CLN-619, CLN-617 (Amber), CLN-978 (NexGem) and Opal (additional information can be found in this press release on our company website).
  • Cullinan recently announced a collaboration with the Icahn School of Medicine at Mount Sinai to develop oral protein degraders targeting hematopoietic progenitor kinase 1 (HPK1), a key regulator of immune cell activation and a high-priority target in immune-oncology. Preclinical research has shown that a degrader approach to targeting HPK1 may be more effective at controlling tumor growth than inhibition of HPK1 kinase activity.
  • In 2021, Cullinan advanced two programs into IND-enabling studies: CLN-617, a cytokine fusion protein uniquely combining IL-12 and IL-2 with a collagen binding domain for retention in the tumor microenvironment (TME), and CLN-978, a novel CD19/CD3-bispecific construct with extended serum half-life and high potency against target cells expressing very low levels of CD19. Cullinan expects to submit INDs for both programs by the end of the first half of 2023.
• Organizational Announcements: Expanded late-stage oncology expertise with appointments of Jeffrey Jones, M.D., MPH, MBA as Chief Medical Officer and Anne-Marie Martin, Ph.D., as an independent director. Dr. Jones joins from Bristol Myers Squibb Company, where he held positions of increasing responsibility in oncology clinical development. Dr. Martin is currently the Senior Vice President, Global Head of the Experimental Medicine Unit at GlaxoSmithKline plc. and joins Cullinan with over 25 years of translational medicine and clinical research expertise.

Fourth Quarter 2021 Financial Results

• Cash Position: Cash, cash equivalents and investments were $430.9 million as of December 31, 2021. We expect that this balance will be sufficient to fund operations through 2024.
• R&D Expenses: Research and development (R&D) expenses were $20.9 million for the fourth quarter of 2021, compared to $12.7 million for the third quarter of 2021. R&D expenses in the fourth and third quarters of 2021 included $2.6 million and $2.5 million of equity-based compensation expenses, respectively. The increase in R&D expenses is primarily related to expanded clinical and chemistry, manufacturing, and controls (CMC) activity for CLN-081 and discovery and development of our preclinical programs.
• G&A Expenses: General and administrative (G&A) expenses were $13.5 million for the fourth quarter of 2021, compared to $5.7 million for the third quarter of 2021. G&A expenses in the fourth and third quarters of 2021 included $9.6 million and $2.1 million of equity-based compensation expenses, respectively. The increase in G&A expenses is primarily related to a non-recurring charge to equity-based compensation expense due to the transition of our chief executive officer.
• Net Loss: The Company’s net loss (before items attributable to noncontrolling interest) was $34.4 million for the fourth quarter of 2021, compared to $18.4 million for the third quarter of 2021. The increase in net loss related primarily to CLN-081 CMC investment, R&D portfolio advancement, and non-recurring equity-based compensation expenses.

Full Year 2021 Financial Results

• R&D Expenses: R&D expenses were $57.8 million for the year ended December 31, 2021, compared to $43.2 million for the year ended December 31, 2020. R&D expenses for the full years 2021 and 2020 included $8.9 million and $5.9 million of equity-based compensation expenses, respectively. The increase in R&D expenses is primarily related to expanded trial enrollment, CMC activities, and a sub-licensing fee relating to CLN-081, as well as increases in pre-clinical and CMC costs to support IND enabling activities for other programs.
• G&A Expenses: G&A expenses were $29.1 million for the year ended December 31, 2021, compared to $17.1 million for the year ended December 31, 2020. G&A expenses for the full years 2021 and 2020 included $15.4 million and $9.0 million of equity-based compensation expenses, respectively. The increase in G&A expenses is primarily related to a non-recurring charge to equity-based compensation expense in the fourth quarter due to the transition of our chief executive officer, as well as increased headcount, legal expenses, insurance costs, and IT systems upgrades to support our operations as a public company.
• Net loss: The Company’s net loss (before items attributable to non-controlling interest) was $67.5 million for the year ended December 31, 2021, compared to $59.5 million for the year ended December 31, 2020. Net loss for the year ended December 31, 2021 included $18.9 million of revenue from the upfront payment pursuant to the license agreement with Zai Lab (Shanghai) Co., Ltd. for the development and commercialization rights to CLN-081 in Greater China, $3.0 million of sub-licensing expense associated with that transaction, and $24.4 million of non-cash equity-based compensation expense.
