Testing AK109 and AK104 for advanced stomach cancer treatment
Official title: A Multicentre, Phase Ib/II Clinical Study of AK109 and AK104 With or Without Chemotherapy in Second-line Treatment of Advanced Gastric Adenocarcinoma or Gastroesophageal Junction Adenocarcinoma
Run by Akeso · NCT04982276 · Data updated 2026-11-12
This study is testing two new treatments, AK109 and AK104, to see if they can help people with advanced stomach cancer who haven't had success with other therapies.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 to 75 with advanced unresectable or metastatic gastric adenocarcinoma or gastroesophageal junction adenocarcinoma who have failed first-line treatment.
✕Probably not a fit
Patients with other invasive malignancies or those who have previously received systemic therapy targeting VEGF may not benefit from this study.

What this trial studies
This clinical trial evaluates the effectiveness of AK109 and AK104, with or without chemotherapy, in patients with advanced gastric adenocarcinoma or gastroesophageal junction adenocarcinoma who have failed first-line treatments. It is a multicenter Phase Ib/II study designed to assess safety, tolerability, and preliminary efficacy of these interventions. Participants will receive either AK109, AK104, or paclitaxel as part of their treatment regimen. The study aims to provide new therapeutic options for patients with limited treatment alternatives.
Why it matters
Potential benefit: If successful, this study could offer a new treatment option for patients with advanced gastric cancer who have not responded to previous therapies.
How similar studies have gone: Other studies have explored similar treatment approaches for gastric cancer, but the specific combination of AK109 and AK104 is novel.
