What this trial studies

This clinical trial aims to assess the safety, tolerability, and pharmacokinetics of ADRX-0706 in patients with select advanced solid tumors, including triple negative breast cancer, urothelial cancer, and cervical cancer. The study is divided into two parts: Phase 1a focuses on dose escalation to determine the recommended dose, while Phase 1b will further evaluate safety, tolerability, and preliminary efficacy at the identified optimal dose. Participants must have previously received systemic treatment and have no available standard therapy options.

Who should consider this trial

Good fit: Ideal candidates include patients with advanced solid tumors, specifically urothelial cancer, triple negative breast cancer, or cervical cancer, who have experienced disease progression after prior treatments.

Not a fit: Patients with early-stage tumors or those who have not received prior systemic therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with advanced solid tumors who have limited therapeutic alternatives.

How similar studies have performed: Other studies have shown promise with similar approaches in targeting advanced solid tumors, indicating potential for success in this trial.

* Phase 1a Dose Escalation: Subjects with histologically confirmed select advanced solid tumors, including urothelial carcinoma (UC), head and neck squamous cell carcinoma (HNSCC), breast cancer, cervical cancer, ovarian cancer, non-small cell lung cancer (NSCLC), and pancreatic cancer. Subjects must have received at least one prior systemic regimen and have no other therapy available known to provide meaningful clinical benefit in the opinion of the investigator.
* Phase 1b Dose Expansion: Subjects with urothelial cancer, triple negative breast cancer or cervical cancer with disease progression after at least one prior systemic regimen and no standard treatment options available and considered appropriate in the opinion of the investigator, unless subject refuses standard therapy.
* Measurable disease according to RECIST version 1.1
* Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
* Adequate hematologic, liver, and renal function
