Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with unresectable advanced solid tumors who have progressed after standard therapies.

Probably not a fit

Patients with resectable tumors or those who have not yet undergone systemic therapy may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This first-in-human trial aims to assess the safety, tolerability, and anti-tumor activity of AMT-116 in patients with advanced solid tumors. The study will determine the Maximum Tolerated Dose (MTD) and the Recommended Phase 2 Dose (RP2D) while also evaluating pharmacokinetics and pharmacodynamics. Eligible participants must have histologically confirmed unresectable tumors and have experienced disease progression after standard therapies. The trial will involve multiple research sites to gather comprehensive data on the treatment's effectiveness.

Why it matters

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

How similar studies have gone: While this approach is novel, similar studies targeting advanced solid tumors have shown promise in evaluating new therapies.

* Systemic anti-neoplastic therapy within five half-lives or 21 days, whichever is shorter, prior to first dose of the IMP.
* Radiotherapy to lung field at a total radiation dose of ≥20 Gy within 6 months, wide-field radiotherapy (e.g., \> 30% of marrow-bearing bones) within 28 days.
* Major surgery (not including placement of vascular access device or tumor biopsies) within 28 days prior to the first dose of the IMP, or no recovery from side effects of such intervention.
