Recruiting now Phase 1 NCT06462183
Run by Rgenta Therapeutics Inc · for 18 and older · All sexes
What this study is about
Phase 1 study to evaluate safety, tolerability and anti-tumor activity of RGT-61159 in patients with ACC or CRC
Who can join (things the study team will check)
✅ You may be able to join if…
- Histologically confirmed ACC or CRC
- Radiographically measurable disease as assessed per RECIST 1.1, with at least 1 site of disease that is measurable and that has not been previously irradiated; or, if the patient has had previous radiation to the target lesion(s), there must be evidence of progression since the radiation
- Patients with locally relapsed/refractory (R/R) advanced or metastatic ACC not amenable to potentially curative surgery or radiotherapy and progression of disease within 12 months at study entry
- Patients with CRC must have locally R/R advanced or metastatic disease not amenable to potentially curative surgery or radiotherapy; must have been previously treated with, or are not considered candidates for, available therapies including fluoropyrimidines-, oxaliplatin-, and irinotecan-based chemotherapies, anti-VEGF agents, and if RAS wild-type, an anti-EGFR therapy.
- Adequate hematologic status, organ function, renal function, liver function and prothrombin time (PT) or INR ≤ 1.5 × ULN and partial thromboplastin time (PTT) or activated partial thromboplastin time (aPTT) ≤ 1.5 × ULN
- Resolved acute effects of any prior therapy to baseline
🚫 You may not be able to join if…
- Major surgery or significant traumatic injury within 28 days prior to Cycle 1 Day 1
- Chemotherapy within 14 days prior to Cycle 1 Day 1
- Use of nitrosoureas or mitomycin C within 6 weeks prior to Cycle 1 Day 1

- Refractory nausea and vomiting, malabsorption, external biliary shunt, or significant small bowel resection that would preclude adequate absorption
- Uncontrolled diabetes
- Treatment with a long-acting hematopoietic growth factor within 14 days before Cycle 1 Day 1 or a short-acting hematopoietic growth factor within 7 days before Cycle 1 Day 1
- Treatment with high-dose chemotherapy and stem-cell rescue (autologous stem cell transplant) or allogeneic stem cell transplant within 90 days before Cycle 1 Day 1
- Patients with central nervous system (CNS) metastases are not eligible, unless they have completed local therapy and have discontinued the use of corticosteroid throughout this indication for at least 4 weeks before starting treatment in this study
- History of solid organ transplantation
