SALT LAKE CITY, UT, USA I October 02, 2024 I Recursion (NASDAQ: RXRX), a leading clinical stage TechBio company decoding biology to industrialize drug discovery, today announced that the U.S. Food and Drug Administration (FDA) has cleared an investigational new drug (IND) application for a Phase 1/2 clinical trial of REC-1245, a new chemical entity for the treatment of biomarker-enriched solid tumors and lymphoma. Chris Gibson, Ph.D., Co-founder and CEO of Recursion said, “REC-1245 is a prime example of using an expansive AI-enabled platform for drug discovery. After exploring many predicted biological and chemical relationships across our maps of biology, we identified RMB39 as a novel target that looks functionally similar to the well-known but hard to drug target CDK12. We also identified and optimized small molecules that target RBM39 without directly impacting CDK12 or CDK13 using these same AI-enabled maps. In under 18 months , leveraging some of our newer chemistry tools, Recursion rapidly progressed REC-1245 from novel target biology to preclinical drug candidate, more than twice the speed of industry average.” Recursion identified the novel regulatory role of RBM39 associated with CDK12 using its maps of biology and first reported this relationship in early 2023 at Download Day, Recursion’s R&D and investor event. Recursion believes the modulation of RBM39 may be associated with a therapeutic effect in certain biomarker-enriched solid tumors and lymphoma. Additionally, Recursion estimates that the initially addressable population for this potential therapeutic to be >100,000 patients in the US and EU5. REC-1245 is a potent and selective RBM39 degrader with a potential first-in-class profile. Preclinical data support that RBM39 degradation induces splicing defects which downregulate DNA Damage Response (DDR) networks and cell cycle checkpoints. “RBM39 degraders may offer a promising therapeutic approach for patients with solid tumors, particularly those with limited treatment options,” said Najat Khan, Ph.D., Chief R&D Officer and Chief Commercial Officer at Recursion. “Recursion’s platform was among the first to rapidly uncover the therapeutic potential of RBM39 degradation, a finding now validated by independent research. This mechanism provides new opportunities for targeting tumors, which are often resistant to conventional treatments. By advancing this research, we aim to deliver a critical option for patients facing significant unmet needs, ultimately improving their prognosis and quality of life.” The Phase 1/2 clinical trial will evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and potential monotherapy efficacy of REC-1245, and is expected to initiate in Q4 2024.

BOSTON, Sept. 23, 2024 (GLOBE NEWSWIRE) -- Carrick Therapeutics Inc., an oncology-focused biopharmaceutical company discovering and developing highly differentiated therapies, today announced that the first patient has been dosed in the Phase 1 clinical trial evaluating CT7439, a novel cyclin dependent kinase 12/13 (CDK12/13) inhibitor / Cyclin-K glue-degrader. CDK12/13 is implicated in multiple cancer types, as they regulate transcription elongation, RNA splicing, as well as cleavage and polyadenylation. DNA damage response genes are particularly suppressed by loss of CDK12/13 activity. The clinical trial is enrolling patients with advanced solid tumors, including ovarian, breast and Ewing's Sarcoma. "Initiation of our CT7439 Phase 1 clinical trial marks the advancement of our second therapeutic into the clinic for aggressive and resistant forms of cancer,” said Tim Pearson, Chief Executive Officer of Carrick Therapeutics. “CT7439 is the first CDK12/13 inhibitor to enter clinical development, and we are encouraged by its potential as monotherapy or combination therapy across multiple tumor types.” The Phase 1 clinical trial is a modular design, beginning with a dose escalation for the initial administration of CT7439 to patients. The initial clinical evaluation will be focused on safety and pharmacokinetics, with an opportunity for early Proof of Principle using a blood based pharmacodynamic assay of the homologous recombination repair (HRR) pathway. Clinical trial details can also be found on www.clinicaltrials.gov under study ID: NCT06600789. For additional information on the clinical trial, please contact hello@carricktherapeutics.com. About CT7439CT7439 is an inhibitor of CDK12/13 as well as a 'glue degrader' of Cyclin-K, which is the obligate co-factor for CDK12/13, giving both first-in-class and best-in-class potential. This dual modality significantly increases the potency of the compound and leads to the inhibition of DNA repair at the transcriptional level. CDK12/13 regulates gene transcription through the activation of RNA Polymerase II. It has the potential to synergise with other agents targeting DDR such as the PARP inhibitors in multiple cancer types, including breast, ovarian and Ewing’s Sarcoma. About Carrick TherapeuticsCarrick Therapeutics is an oncology-focused biopharmaceutical company developing highly differentiated novel therapies that address significant unmet needs. The Company’s lead program, samuraciclib, is a novel oral first-in-class inhibitor of CDK7 currently in multiple Phase 2 clinical trials for metastatic HR+ breast cancer. The Company is collaborating with Roche, Menarini Group and Arvinas/Pfizer to evaluate novel combinations of samuraciclib with oral SERD endocrine therapies. Additionally, Carrick is developing CT7439, a novel CDK12/13 inhibitor / Cyclin-K glue-degrader, which is currently in a Phase 1 clinical trial.
