Follow-up Cullinan Pearl data from Phase 1 portion of ongoing trial showed increased disease control rate (DCR) of 92% in the 100mg dose cohort

IND clearance of two immuno-oncology pipeline programs, Cullinan MICA and Cullinan Florentine, with clinical trial starts for each program expected in 2H 2021

Strong balance sheet with cash and investments of $456.3 million as of June 30, 2021

CAMBRIDGE, Mass., Aug. 10, 2021 (GLOBE NEWSWIRE) -- Cullinan Oncology, Inc. (Nasdaq: CGEM), an oncology company seeking to drive shareholder returns by focusing on the patient, today announced its financial results for the second quarter ended June 30, 2021 and reported on recent business highlights.

“Solid execution led to the advancement of our clinical pipeline this quarter,” stated Owen Hughes, Chief Executive Officer of Cullinan Oncology. “We are pleased with the encouraging results of Cullinan Pearl (EGFR exon 20) showcased at ASCO as well as the recent IND clearance for the first two programs in our immuno-oncology pipeline, Cullinan MICA (MICA/B antibody) and Cullinan Florentine (FLT3 bispecific). With over $456 million of cash and investments on hand, we remain well capitalized to advance our broad pipeline through multiple clinical readouts. In the near term, we expect to provide updated preclinical data on Cullinan Amber at the Next-Gen Cytokine Therapeutics Summit in September as well as a Cullinan Pearl clinical and regulatory update in the fourth quarter.”

Q2 2021 Portfolio Highlights

  • Cullinan Pearl: Presented interim data at ASCO 2021 from ongoing Phase 1/2a trial evaluating CLN-081 in non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) exon 20 mutations (press release).
    • Safety: CLN-081 continues to demonstrate promising overall safety and tolerability, with an encouraging GI toxicity profile.
    • Efficacy: As of the ASCO data cutoff, there were 5 pending partial responses (PR), 4 of which subsequently confirmed. In addition, follow-up data from patients in the 100mg Phase 1 cohort showed the DCR, defined as best response of PR + stable disease ≥6 months, increased to 92% (12 / 13 patients).
    • Phase 1/2a trial status: Cullinan recently completed enrollment of the Phase 2a 100mg expansion cohort (total n=36) and initiated expansion at 150mg (from 7 patients treated to date to 13 total). Cullinan intends to provide a clinical and regulatory update in Q4 2021.
  • Cullinan MICA: Received U.S. Food and Drug Administration (FDA) clearance of Investigational New Drug application (IND) for CLN-619, a novel MICA/B-targeted antibody for the treatment of solid tumors (press release). CLN-619 is a first-in-class monoclonal antibody designed to promote an antitumor response by engaging both natural killer (NK) and T cells through the MICA/B–NKG2D axis, with therapeutic potential for both solid and liquid tumor indications. Cullinan intends to initiate a first-in-human (FIH) trial of CLN-619 in 2H 2021, including a dose escalation cohort followed by dose expansion cohorts as a monotherapy and in combination with checkpoint inhibitor therapy.
  • Cullinan Florentine: Received FDA clearance of IND for CLN-049, a FLT3 x CD3 bispecific antibody for the treatment of relapsed/refractory acute myeloid leukemia (AML) (press release). CLN-049 is designed to simultaneously bind to FLT3 on target leukemic cells and to CD3 on T cells, triggering the T cells to kill the targeted cancer cells via their intrinsic cytolytic mechanisms. Studies have shown that FLT3 is expressed on AML blasts in over 75% of AML patients, regardless of FLT3 mutational status. Cullinan intends to initiate a FIH trial of CLN-049 in 2H 2021.
  • Cullinan Amber: Continued progress towards final candidate selection for CLN-617, a fusion protein combining two potent antitumor cytokines, IL-2 and IL-12, in a single molecule with a collagen-binding tumor retention domain for the treatment of solid tumors. IND-enabling studies are planned to commence in the 2H 2021.
  • Cullinan NexGem: Continued to progress CLN-978, an internally developed half-life extended T cell engager designed to simultaneously engage CD19 and CD3, through IND-enabling development.

Q2 2021 Financial Results

  • Cash Position: Cash, cash equivalents and investments were $456.3 million as of June 30, 2021, compared to $473.0 million as of March 31, 2021. Net cash used in operating activities for the second quarter of 2021 was $16.4 million.
  • R&D Expenses: Research and development (R&D) expenses were $11.8 million for the second quarter of 2021, including $2.3 million of non-cash equity-based compensation expense, compared to $12.5 million for the second quarter of 2020. The decrease in R&D expenses is primarily related to a non-recurring non-cash charge related to the MICA acquisition in the second quarter of 2020, partially offset by increased expenses from headcount growth as well as expanded clinical and CMC activity from other portfolio programs.
  • G&A Expenses: General and administrative (G&A) expenses were $4.8 million for the second quarter of 2021, including $1.9 million of non-cash equity-based compensation expense, compared to $1.6 million for the second quarter of 2020. The increase in G&A expenses is primarily related to headcount growth as well as additional costs associated with operations as a public company.
  • Net loss: The Company’s net loss (before items attributable to noncontrolling interest) was $16.4 million for the second quarter of 2021, compared to $13.9 million for the second quarter of 2020, driven predominantly by increases in costs associated with public company operations and non-cash equity-based compensation expenses.
