Description of intervention(s) / exposure
Treatment: Drugs - S095029
Treatment: Drugs - pembrolizumab 200 mg (KEYTRUDA ®)

Experimental: S095029 and pembrolizumab - Participants diagnosed with gastric cancer (GC) or gastroesophageal junction cancer (GEJ), not previously treated with checkpoint inhibitors (CPIs) may first be enrolled into a Phase 1b safety lead-in part which will be used to identify the recommended Phase 2 dose (RP2D) of S095029 in combination with pembrolizumab. During the Phase 2 part, participants will receive the recommended Phase 2 dose (RP2D) of S095029, along with pembrolizumab.


Treatment: Drugs: S095029
Participants will be treated with S095029 via intravenous (IV) infusion every 3 weeks (Q3W).

Treatment: Drugs: pembrolizumab 200 mg (KEYTRUDA ®)
Participants will be treated with 200 mg of pembrolizumab via intravenous (IV) infusion every 3 weeks (Q3W).
