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), cetuximab (EGFR inhibitor) or FOLFIRI plus cetuximab (EGFR inhibitor) in patients with advanced refractory / resistant solid malignancies including metastatic colorectal cancer (mCRC) patients.
Accepts Healthy Volunteers

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies. |

Trial ID:
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries. |
NCT04485013 |
Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |

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 Phase 1b includes randomized arms with TTX-080 in combination with FOLFIRI plus cetuximab compared to FOLFIRI plus cetuximab in metastatic Colorectal cancer. The study will seek to evaluate the pharmacokinetics and immunogenicity of TTX-080, and characterize the anti-tumor activity of TTX-080 as a monotherapy and in combination with pembrolizumab, cetuximab or FOLFIRI plus cetuximab.

Prior bevacizumab allowed. No prior EGFR inhibitor.
Experimental: FOLFIRI plus cetuximab
