Is this trial a fit for you?

Likely a good fit

Adults aged 18 to 75 with histologically or cytologically confirmed advanced SCLC, at least one measurable lesion, ECOG 0–1, and adequate organ function.

Probably not a fit

Patients without measurable disease, unfavorable performance status, or those who discontinue due to adverse events or disease progression may not receive benefit.

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

What this trial studies

This is a multi-regional, open-label Phase 1 trial evaluating the safety, tolerability, and preliminary activity of IBI115 as a single agent and in combination therapy for adults with advanced small cell lung cancer. Participants must have measurable disease, good performance status, and adequate organ function. The study screens for eligibility and monitors adverse events, tumor response by RECIST, and preliminary efficacy signals to guide further development. Enrollment is at a single site in Chongqing, China, sponsored by Innovent Biologics with collaboration from the hospital site.

Why it matters

Potential benefit: If successful, participants might experience stabilization or reduction of tumors and manageable side effects, potentially informing future therapies for SCLC.

How similar studies have gone: Previous early-phase studies of similar investigational agents in SCLC have shown safety signals and hints of activity, but full efficacy remains to be demonstrated in larger trials.
