7MW3711 plus JS207 for advanced solid tumors
Official title: A Multi-center, Open-label, Phase Ib/II Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetic and Preliminary Efficacy of 7MW3711 in Combination With JS207 With or Without Chemotheray in Patients With Advanced Solid Tumors
Run by Mabwell (Shanghai) Bioscience Co., Ltd. · NCT07466160 · Data updated 2026-11-12
This trial tests whether combining the experimental drugs 7MW3711 and JS207, with or without platinum chemotherapy, can help adults with advanced or metastatic solid tumors that have progressed after standard treatments.

Is this trial a fit for you?
✓Likely a good fit
Adults with histologically or cytologically confirmed locally advanced or metastatic solid tumors, measurable disease, ECOG 0–1, adequate organ function, and progression after or intolerance of standard therapies are the intended participants.
✕Probably not a fit
Patients with active or untreated central nervous system metastases, recent other malignancies within three years, or inadequate hematologic, renal, or hepatic function are unlikely to qualify and may not benefit from this investigational regimen.

What this trial studies
This multicenter, open-label Phase Ib/II study gives escalating doses of 7MW3711 with JS207, with or without cisplatin or carboplatin, to evaluate safety, tolerability, pharmacokinetics and preliminary antitumor activity. Phase Ib uses dose-escalation to identify recommended doses and characterize side effects, while Phase II expands selected tumor cohorts to measure response by RECIST v1.1. Eligible patients must have measurable disease, ECOG 0–1, adequate organ function, and prior progression on or intolerance to standard therapies. Patients receive study drugs per protocol with regular imaging and laboratory monitoring for efficacy and adverse events.
Why it matters
Potential benefit: If successful, the combination could provide a new treatment option that shrinks tumors or slows disease progression for some patients with advanced solid tumors.
How similar studies have gone: Some investigational agent plus platinum combinations have shown activity in particular solid tumors, but 7MW3711 and JS207 are novel agents with limited prior clinical data and remain unproven.
