Is this trial a fit for you?

Likely a good fit

Adults aged 18–75 with advanced NSCLC, recurrent/metastatic HNSCC, colorectal adenocarcinoma, or other advanced solid tumors who have ECOG 0–1 and meet the study's prior-treatment criteria are the intended participants.

Probably not a fit

Patients with poor performance status (ECOG >1), life expectancy under three months, cancers not listed, or who do not meet the cohort-specific prior-treatment requirements are unlikely to 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 is an open-label, multicenter phase Ib/II trial designed to confirm the recommended Phase II dose (RP2D) and to evaluate safety and early signs of efficacy for AK129 given in combination with standard chemotherapies. The program uses dose-escalation cohorts followed by expansion cohorts in tumor-specific groups including NSCLC, HNSCC, and colorectal adenocarcinoma. Interventions include AK129 at two dose levels combined with agents such as pemetrexed, paclitaxel, or carboplatin depending on the cohort. Eligible patients are adults (18–75) with ECOG 0–1 and meet tumor- and prior-treatment–specific criteria, and primary endpoints focus on safety and dose with secondary endpoints addressing anti-tumor activity.

Why it matters

Potential benefit: If successful, these AK129 combinations could provide a new treatment option that improves tumor control or extends survival for some patients with advanced solid tumors.

How similar studies have gone: Combining novel agents with platinum-based chemotherapy and PD-(L)1–directed approaches has shown benefit in some cancer types, but AK129 appears to be a novel agent with limited published clinical data to date.
