• Expanded clinical stage portfolio through licensing of U.S. rights to CLN-418
  
• Received FDA clearance of IND application for CLN-978; submitted IND application for CLN-617
• Initial clinical data updates for CLN-049 and CLN-619 on track for mid-2023
• Potential for 6 clinical stage programs by year end and cash runway into 2026

CAMBRIDGE, Mass., March 09, 2023 (GLOBE NEWSWIRE) -- Cullinan Oncology, Inc. (Nasdaq: CGEM; “Cullinan”) a biopharmaceutical company focused on modality-agnostic targeted oncology therapies, today reported on recent and upcoming business highlights and announced its financial results for the fourth quarter and full year ended December 31, 2022.

“2022 was a year of remarkable execution at Cullinan Oncology, and the momentum with which we ended the year has continued into early 2023. With our partners at Taiho Oncology, we initiated the pivotal study of zipalertinib in the fourth quarter, while continuing to advance enrollment in the Phase 1 trials of CLN-049 and CLN-619, with initial clinical data expected mid-year," said Nadim Ahmed, Chief Executive Officer of Cullinan. “The first two months of 2023 have resulted in similarly exciting developments, as we recently expanded our pipeline through the licensing of U.S. development and commercial rights to CLN-418, a potential first-in-class B7H4x4-1BB bispecific immune activator currently in a Phase 1 study across a variety of solid-tumor indications. This transaction provides us with the opportunity to have six programs in the clinic by the end of the year, as we recently received IND clearance for CLN-978 and also recently filed the IND for CLN-617, consistent with prior guidance. Importantly, our cash position following the CLN-418 transaction provides us with runway into 2026 which gives us the flexibility needed to fund our ongoing development efforts and reach multiple potential value creating milestones.”

Portfolio Highlights

• Zipalertinib:  In the fourth quarter of 2022, Cullinan Oncology, in collaboration with our partners at Taiho Oncology, Inc., initiated a pivotal study of zipalertinib in EGFR exon 20 insertion mutation non-small-cell lung cancer patients progressing after prior systemic therapy. As previously planned, the study will enroll patients at the 100mg BID dose under fasted conditions, and also will include a limited cohort of patients to evaluate safety and efficacy at 150mg BID administered with food.
• CLN-049: CLN-049 is a FLT3xCD3 T cell-engaging bispecific antibody being investigated in patients with relapsed/refractory acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). Enrollment continues in the ongoing Phase 1 dose escalation clinical study with initial clinical data expected in mid-2023.
• CLN-619: CLN-619 is a monoclonal antibody that stabilizes expression of MICA/MICB on the tumor cell surface to promote tumor cell lysis by both cytotoxic innate and adaptive immune cells. CLN-619 has broad therapeutic potential and is being investigated as both monotherapy and in combination with checkpoint inhibitor therapy in an ongoing Phase 1 dose escalation study in patients with advanced solid tumors with initial clinical data expected in mid-2023.
• CLN-418: CLN-418 is a B7H4x4-1BB fully human bispecific immune activator designed to achieve conditional activation of 4-1BB by targeting B7H4, a tumor associated antigen that is highly expressed across multiple cancers with minimal expression on normal tissues. Enrollment is ongoing in a Phase 1 dose escalation study at U.S. and Australian sites in patients with advanced solid tumors with initial clinical data expected in 2024.
  • In February, Cullinan Oncology licensed the exclusive U.S. development and commercial rights to CLN-418 from Harbour Biomed for an upfront fee of $25 million, with the potential for up to an additional $148 million in development and regulatory milestones and up to $415 million in sales-based milestones, as well as tiered royalties on potential U.S. commercial sales.

• CLN-978: CLN-978 is a novel CD19xCD3-bispecific therapeutic with extended serum half-life and robust potency against target cells expressing low levels of CD19. Consistent with prior guidance, Cullinan received FDA clearance of its Investigational New Drug (IND) application for CLN-978 in January and anticipates initiating a Phase 1 clinical study by the end of 2023.

• CLN-617: CLN-617 is 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. Consistent with prior guidance, Cullinan recently filed the IND application for CLN-617 in February 2023 and intends to initiate a Phase 1 clinical study by the end of 2023, pending IND clearance.

Fourth Quarter 2022 Financial Results

• Cash Position: Cash and investments were $550.1 million as of December 31, 2022. During the fourth quarter of 2022, Cullinan acquired additional equity in its subsidiary, Cullinan Mica, which holds the worldwide rights to CLN-619, for $33 million, increasing its ownership from 54% to 95% of the entity. In the first quarter of 2023, the Company spent $25 million on the upfront payment under the recently announced licensing agreement for CLN-418 with Harbour Biomed. Cullinan expects its cash resources to provide runway into 2026 based on its current operating plan.
• R&D Expenses: Research and development (R&D) expenses were $21.3 million for the fourth quarter of 2022, compared to $19.7 million for the third quarter of 2022. R&D expenses for the fourth and third quarters of 2022 included $2.9 million and $1.1 million of equity-based compensation expenses, respectively. Excluding the impact of equity-based compensation expenses, the decrease in R&D expenses was primarily related to a decrease in preclinical costs, partially offset by increased personnel costs.
• G&A Expenses: General and administrative (G&A) expenses were $11.3 million for the fourth quarter of 2022, compared to $10.1 million for the third quarter of 2022. G&A expenses in the fourth and third quarters of 2022 included $4.6 million and $4.2 of equity-based compensation expenses, respectively. The increase in G&A expenses was primarily driven by increased personnel costs.
• Net Loss: Net loss (before items attributable to noncontrolling interest) for the fourth quarter of 2022 was $27.1 million, compared with net loss of $24.9 million for the third quarter of 2022. Net losses included the items described above, partially offset by interest income of $3.4 million and $2.4 million and income tax benefit recognized of $1.9 million and $2.5 million in the fourth and third quarters of 2022, respectively.

Full Year 2022 Financial Results

• R&D Expenses:  R&D expenses were $91.9 million for 2022, compared to $57.8 million for 2021. R&D expenses for 2022 and 2021 included $11.0 million and $8.9 million of equity-based compensation expenses, respectively. The increase in R&D expenses was primarily related to CRO and CMC activities to support our ongoing clinical trials and pre-clinical research and CMC costs to support IND enabling activities.
• G&A Expenses:  G&A expenses were $40.2 million for 2022, compared to $29.1 million in 2021. G&A expenses in 2022 and 2021 included $16.9 million and $15.4 million of equity-based compensation expenses, respectively. The increase in G&A expenses was primarily driven by increase in personnel and professional services due to increased headcount to support our expanded operations, and non-recurring costs related to the previously announced Cullinan Pearl sale, described below.
• Gain on sale of Cullinan Pearl: In June 2022, Cullinan sold its equity interest in its subsidiary, Cullinan Pearl, which has worldwide rights to zipalertinib, excluding Japan and Greater China, to Taiho Pharmaceutical Co., Ltd. (Taiho). Cullinan recognized a gain from the sale of $276.8 million, which includes the upfront payment of $275 million, as well as the impact of net liabilities transferred to Taiho. Cullinan also recognized income tax expenses of $42.1 million as a result of the gain and offsetting operating expenses.
• Net Income (Loss): Net income (before items attributable to noncontrolling interest) for 2022 was $109.2 million, compared with a net loss of $67.5 million in 2021. Net income in 2022 was related to the items described above, as well as $6.6 million of interest income. In 2021, operating expenses described above were partially offset by $18.9 million of license revenue.
