Cash and investments of $656 million1 as of June 30, 2022 expected to provide runway through 2026.

CAMBRIDGE, Mass., Aug. 10, 2022 (GLOBE NEWSWIRE) -- Cullinan Oncology, Inc. (Nasdaq: CGEM), a biopharmaceutical company focused on developing a diversified pipeline of targeted therapeutic candidates across multiple modalities for patients with cancer, today reported on recent and upcoming business highlights and announced its financial results for the second quarter ended June 30, 2022.

“In the second quarter of 2022, Cullinan Oncology demonstrated significant portfolio advancement, including the closing of our agreement with Taiho Pharmaceutical for CLN-081, an oral presentation for CLN-081 at the American Society of Clinical Oncology (ASCO) 2022 Annual Meeting, and continued progression of our pipeline of potential first-in-class and best-in-class oncology assets. These achievements demonstrate our commitment to creating new standards of care for patients with unmet need,” said Nadim Ahmed, Chief Executive Officer of Cullinan Oncology.

“We are pleased with the continued strengthening of CLN-081’s clinical profile,” Ahmed continued. “Updated data released at ASCO highlighted a high response rate, favorable safety and tolerability, and improving durability of response from the ongoing Phase 1/2a study for patients with EGFR exon 20 insertion mutation non-small-cell lung cancer. Financially, the closing of the Taiho transaction for CLN-081 has extended our cash runway through 2026, giving us the financial flexibility to accelerate and expand the development of our diverse pipeline as well as obtain promising new oncology assets. Looking ahead, we continue to advance our earlier-stage programs, including CLN-619 and CLN-049, with initial Phase 1 data readouts expected by mid-2023, as well as CLN-617 and CLN-978, for which we anticipate IND filings in the first half of next year.”

Portfolio Highlights

  • CLN-081:  In June, Cullinan Oncology completed its strategic agreement with Taiho Pharmaceutical Co., Ltd. (Taiho Pharmaceutical) pursuant to which Cullinan Oncology received a $275 million upfront payment and is eligible to receive an additional $130 million tied to EGFR exon 20 non-small-cell lung cancer regulatory milestones in exchange for selling its equity interest in Cullinan Pearl, which holds worldwide rights to CLN-081 outside of Japan and Greater China. Additionally, Cullinan Oncology entered into an agreement with Taiho Oncology, Inc. (Taiho Oncology), a subsidiary of Taiho Pharmaceutical, to jointly develop and commercialize CLN-081 in the U.S. Pursuant to the co-development agreement, Cullinan Oncology and Taiho Oncology will share equally in the development expenses and future potential U.S. profits and losses for CLN-081.

  • Also in June, Cullinan Oncology presented updated data from its ongoing Phase 1/2a clinical study of CLN-081 in an oral presentation at the ASCO 2022 Annual Meeting. The updated data showed a median duration of response greater than 21 months, median progression free survival of 12 months and a confirmed overall response rate of 41% among 39 patients treated at the 100 mg BID dose, along with a continued favorable safety and tolerability profile. In collaboration with its partner, Taiho Oncology, Cullinan Oncology intends to initiate a pivotal study for CLN-081 in the second half of 2022 under the co-development agreement.

  • CLN-049: Cullinan Oncology continued dosing patients in its first-in-human clinical trial evaluating CLN-049 in patients with relapsed/refractory acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). Initial clinical data are expected by mid-2023. CLN-049 is a FLT3/CD3-bispecific T cell-engaging antibody in an IgG format for the treatment of AML and MDS. CLN-049 targets the extracellular domain of FLT3, regardless of mutant or wild type FLT3 status.

  • CLN-619: Cullinan Oncology continued dosing subjects in its first-in-human clinical trial evaluating CLN-619 alone and in combination with pembrolizumab in patients with advanced tumors. Initial clinical data are expected by mid-2023. CLN-619 is a first-in-class monoclonal antibody with broad therapeutic potential across multiple cancer indications. CLN-619 stabilizes expression of MICA/MICB on the tumor cell surface to promote an antitumor response via activation of both natural killer (NK) cells and certain T cells.

  • Preclinical Portfolio:

    • Cullinan Oncology remains on track for Investigational New Drug (IND) submissions in the first half of 2023 for its two most advanced preclinical programs:

      • CLN-617, a cytokine fusion protein uniquely combining IL-12 and IL-2 with a collagen binding domain designed for retention in the tumor microenvironment (TME) following intratumoral injection, and

      • CLN-978, a novel CD19/CD3-bispecific construct with extended serum half-life and high potency against target cells expressing low levels of CD19.

    • Cullinan Oncology continues to progress its additional 3 preclinical programs, including Jade, Opal, and the HPK1 degrader collaboration with Icahn Mount Sinai.
