Brief Title: TTX-080 HLA-G Antagonist in Subjects With Advanced Cancers
Official Title: A Phase 1a/1b Dose Escalation/Expansion Study of TTX-080, an HLA-G Antagonist, as Monotherapy and in Combination With Pembrolizumab or Cetuximab in Patients With Advanced Solid Refractory/Resistant Malignancies
Study ID: NCT04485013
Brief Summary: TTX-080-001 is a Phase 1, open label, dose escalation and dose expansion clinical study to determine the safety, tolerability, and recommended Phase 2 dose of TTX-080 monotherapy (HLA-G inhibitor) and in combination with either pembrolizumab (PD-1 inhibitor) or cetuximab (EGFR inhibitor) in patients with advanced refractory / resistant solid malignancies.
Detailed Description: TTX-080 is a fully human mAb designed to block the interaction of HLA-G with its known ligands, ILT2 and ILT4 molecules. The Phase 1a was an open label, multicenter, dose escalation clinical trial to determine the safety, tolerability, MTD or OBD and the RP2D of TTX-080 when administered as a single agent. The Phase 1b is a dose expansion of TTX-080 monotherapy and in combination with either pembrolizumab or cetuximab in adult subjects with advanced refractory/resistant solid malignancies, including Head and Neck squamous cell carcinoma (HNSCC), Non-Small Cell Lung Cancer (NSCLC), Colorectal cancer (CRC), triple negative breast cancer (TNBC), renal cell carcinoma (RCC), and acral melanoma. Additionally, the study will seek to evaluate the pharmacokinetics and immunogenicity of TTX-080, and preliminary efficacy of TTX-080 as a monotherapy and in combination with pembrolizumab or cetuximab.
