Recruiting studies
- NCT05924841RecruitingPhase 2
Study drugs for advanced small cell lung cancer after prior treatments
This Phase 2 trial tests how well two study drugs (and a combination of them) work in people with extensive-stage small cell lung cancer. It’s mainly for patients whose cancer has come back or who couldn’t tolerate at least some standard treatments, and it aims to see if treatment can shrink tumors and be tolerable.
Changchun, JilinAges 18–75 - NCT05956587RecruitingPhase 2
Testing two study drugs for advanced lung cancer and other tumors
This Phase 2 study tests a combination of two experimental medicines in people with advanced or metastatic solid cancers, including non-small cell lung cancer and nasopharyngeal cancer. It aims to see whether the drugs can shrink tumors and improve outcomes, while carefully checking safety and eligibility.
Chongqing, Chongqing MunicipalityAges 18–75 - NCT05965856RecruitingPhase 2
Testing two antibody medicines for advanced bladder and other cancers
This Phase 2 trial studies whether the study medicines SI-B003 alone or together with BL-B01D1 plus SI-B003 can shrink or control advanced cancers that have not responded to standard treatment (or where standard treatment isn’t possible). It also looks at safety and how well the treatment works in people whose cancer can be measured on scans.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05990803RecruitingPhase 2
Testing new drugs for advanced cervical and gynecologic cancers
This trial tests a new drug called BL-B01D1, alone or combined with another drug (SI-B003), for people with cervical or other gynecologic cancers that have spread or come back after standard treatments. The goal is to see if this treatment can help when other options have stopped working.
Beijing, Beijing MunicipalityAges 18–75 - NCT06006169RecruitingPhase 2
Study of new drugs for head and neck cancer and other solid tumors
This trial tests two new drugs, BL-B01D1 and SI-B003, alone or together, for people with head and neck squamous cell carcinoma that has come back or spread. It may also include other solid tumors. The goal is to see if these drugs can shrink tumors or slow their growth.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06008054RecruitingPhase 2
New drug combo for advanced gastrointestinal cancers
This trial tests two new drugs (BL-B01D1 and SI-B003) alone or with a standard immunotherapy for advanced gastrointestinal cancers. The goal is to see if these combinations shrink tumors and are safe.
Beijing, Beijing MunicipalityAges 18–75 - NCT06042894RecruitingPhase 2
Study of two drugs for advanced HER2-negative breast cancer
This trial tests two experimental drugs, SI-B003 and BL-B01D1 plus SI-B003, for people with HER2-negative breast cancer that has spread or cannot be removed by surgery. It is for those who have tried standard treatments or cannot have them.

Common questions
- Are there clinical trials studying SI-B003?
- Yes. Clin2 currently lists 7 recruiting studies that include SI-B003, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a SI-B003 trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is SI-B003 an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether SI-B003 or a specific trial is right for you.
