Treadwell Therapeutics Announces A Presentation at the 2022 SITC Annual Meeting Featuring a Clinical Trial Update on CFI-402411, a First-in-Class HPK1 inhibitor
"We are encouraged by the emerging clinical profile of CFI-402411," said Dr. Michael Tusche , co-Chief Executive Officer at Treadwell Therapeutics. "We hope to define the Recommended Phase 2 dose for the molecule in the near term, and are excited about the next stage of development for CFI-402411 both as a monotherapy and in combination with checkpoint blockade."

In the presentation titled, " CFI-402411 demonstrated a clinically manageable safety profile at doses up to 560 mg QD with exposures increasing proportionately with dose. In the efficacy evaluable population (N=31), 2 patients achieved partial response as best response. Both of responses were in Head and Neck Squamous Cell Carcinoma (HNSCC) patients previously treated with pembrolizumab. One patient was treated as a monotherapy (400 mg) and the other treated in combination (60 mg + pembrolizumab) with 36% and 81% reduction in target lesions, respectively. Nine patients had best response as stable disease and stayed on study for at least 4 cycles. The most common treatment emergent toxicities of any grade, which occurred in greater than 10% of patients, were diarrhea (61%), fatigue (39%), nausea (33%), decreased appetite (30%), vomiting (26%), dehydration (17%), ALT increase (15%). dyspepsia (15%) and back pain (11%).
CFI-402411 is a highly potent inhibitor of HPK1, which in preclinical studies has been shown to have an immune-activating effects including the alleviation of inhibition of T cell receptors (TCR), disruption of abnormal cytokine expression, alteration of the tumor immunosuppressive environment through effector cells (i.e. Regulatory T cells or Treg), and potent anti-leukemic effects in several mouse models.
TWT-101 is a Phase 1/2 clinical trial of CFI-402411 in advanced solid malignancies. The study is designed to assess the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of CFI-402411, as well as to determine optimal dosing as a monotherapy and in combination with the anti-PD1 antibody, pembrolizumab. The trial could enroll up to 170 patients at up to 15 sites in North America and Asia . It will involve 5 arms including monotherapy and combination dose escalation and expansion in a variety of tumor types, as well as biomarker backfills
