SNC115 injections for patients with advanced lung cancer

To Evaluate the Safety and Pharmacokinetic of SNC115 Injections in Patients With Recurrent/Refractory Small Cell Lung Cancer and Lung Large Cell Neuroendocrine Crcinoma: an Open-label, Single-arm, Dose Escalation Exploratory Study

Phase 1 Interventional Shanghai Simnova Biotechnology Co.,Ltd. · NCT06384482

This study is testing a new injection called SNC115 to see if it is safe and effective for people with advanced lung cancer that hasn't responded to other treatments.

What this trial studies

This clinical trial is a first-in-human dose escalation study designed to evaluate the safety and pharmacokinetics of SNC115 injections in patients with recurrent or refractory small cell lung cancer and lung large cell neuroendocrine carcinoma. The study will enroll up to 35 participants, who will receive varying doses of the treatment based on a predetermined escalation plan. Participants will undergo a series of procedures including mononuclear cell acquisition, lymphodepletion, and follow-up assessments over a period of 1 to 5 years to monitor treatment effects and safety outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with recurrent or refractory small cell lung cancer or lung large cell neuroendocrine carcinoma who have not responded to standard therapies.

Not a fit: Patients with known allergies or contraindications to SNC115 injection will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat lung cancers.

How similar studies have performed: While this approach is novel, similar CAR-T therapies have shown promise in other cancer types, indicating potential for success.
