741 TWT-101: a first-in-clinic study of CFI-402411, a hematopoietic progenitor Kinase-1 (HPK1) inhibitor, as single agent or combined with pembrolizumab in subjects with advanced solid malignancies
Notice bibliographique
Résumé
<h3>Background</h3> CFI-402411, a potent HPK1 inhibitor, may promote T-cell response to tumors through a variety of mechanisms that enhance T-cell function in the cancer immunity cycle, and potentially in settings where antigens are expressed poorly and heterogeneously.<sup>1</sup> Preliminary results demonstrated tolerable safety profile with efficacy signals in select tumor types.<sup>2</sup> <h3>Methods</h3> In this ongoing phase 1/2 study, part A evaluates CFI-402411 daily dose (3+3 design) and dose expansion; part B evaluates CFI-402411 in combination with pembrolizumab (200mg) as BOIN design and dose expansion in pembrolizumab eligible tumors. Dose limiting toxicity (DLT) is any grade ≥3 toxicity in cycle 1. Starting dose was 80mg. <h3>Results</h3> At 02-May-2023 the study enrolled 59 patients (pts; A, 40pts; B, 19pts). In US, checkpoint inhibitor (CPI) pretreated patients were eligible. Diagnoses in ≥2pts for A: colorectal (11pts), melanoma (6pts), pancreatic (5pts) and non-small cell lung and prostate (2pts each) cancers; for B: head and neck squamous cell (HNSCC; 3pts) and esophageal, non-small cell lung and small cell lung cancers (2pts, each). Part A tested 9 dose levels (80 - 800mg). B tested 5 dose levels (60 - 400mg) to date. Immune-related AEs (irAE) were reported in 7 pts (A; 18%) and 5 pts (B; 26%). Grade ≥3 AEs occurred in 25 pts (A: 63%) and 10pts (B: 53%). SAE’s occurred in 21 pts (A: 53%) and 11 pts (B: 58%). Diarrhea was the most common TEAE (A: 73%; B: 47%), related AE (A: 63%; B: 42%), irAE (A: 15%; B: 11%), and grade ≥3 AE in A (18%). Most common grade ≥3 AE in B was pulmonary embolism (PE) and AST increase (11% both). The most common SAE was sepsis (A: 15%) and PE (B: 11%). Diarrhea was the most common DLT occurring at 400mg+pembro; 800mg, 720mg, 640mg monotherapy doses. Disease control rates (CR, PR, or SD ≥ 6 weeks from baseline) at 3 months were 18% (A) and 29% (B). Two HNSCC pts achieved a PR (A: 400mg) and confirmed CR (B: 60mg+pembro). A third HNSCC pt’s (B: 400mg+pembro) tumor lesion size reduced 16% at week 5 and pt remains on study. One RCC pt achieved long term SD, 2 years. All 4 pts had prior CPI exposure. <h3>Conclusions</h3> CFI-402411 is well-tolerated with a manageable AE profile. Responses as monotherapy and in combination with CPI in CPI exposed patients were seen. Monotherapy part A expansion at 560 mg is underway in HNSCC and RCC. <h3>Acknowledgements</h3> Treadwell Therapeutics would like to thank both the patients and the research staff at enrolling centers who have helped to bring this novel therapy to the clinic. <h3>Trial Registration</h3> NCT04521413 <h3>References</h3> You D, Hillerman S, Locke G, <i>et al.</i> Enhanced antitumor immunity by a novel small molecule HPK1 inhibitor. <i>J Immunother Cancer</i> 2021;<b>9</b>(1):e001402 Papadopoulos K, Fu S, Hamilton E<i>, et al.</i> TWT-101: a first-in-clinic, phase 1/2 study of CFI-402411, a hematopoietic progenitor kinase-1 (HPK1) inhibitor, as a single agent and in combination with pembrolizumab in subjects with advanced solid malignancies. <i>Journal for ImmunoTherapy of Cancer</i> 2022;<b>10:</b>doi: 10.1136/jitc-2022-SITC2022.0750 <h3>Ethics Approval</h3> This study obtained ethics approvals; Papadopoulos; ID: Pro00051609 Fu; ID2020–0678 Hamilton; ID: Pro00051611 Spira; ID: Pro00043629 Laurie; CTO Project ID 3320 Wang; ID: Pro00051611 Ma; CREC Ref: 2020.367-T Spreafico; CTO Project ID 3320 Sharma; ID Pro00051609 Chu; ID: HREBA.CC-20–0504_REN1 Hamid; IRB: 2020236 <h3>Consent</h3> As evidenced by verified clinical database information all subjects gave informed consent before taking part in this clinical trial.
