A Study to Investigate the Efficacy and Safety of Tislelizumab Combined With Anlotinib as Maintenance Therapy for ES-SCLC

ClinConnect Summary

This clinical trial is studying a new treatment combination for patients with extensive stage small cell lung cancer (ES-SCLC) who have not received any prior treatment. The trial is looking at whether combining two medications, called tislelizumab and Anlotinib, can be safely used as maintenance therapy after patients have received chemotherapy. Maintenance therapy aims to help keep the cancer from growing or coming back after initial treatment. This study is currently recruiting participants aged 18 to 75 who have been diagnosed with ES-SCLC and meet certain health criteria, such as having a good performance status and adequate organ function.

If you or someone you know is interested in participating, you can expect to receive the study medications and regular check-ups to monitor your health and the effects of the treatment. Participants will also need to follow some guidelines regarding their health and treatments received before joining. It’s important to note that this study is not for everyone, as there are specific exclusion criteria like recent treatments, certain health conditions, or active infections that could affect participation. If eligible, this trial could provide access to a potentially beneficial treatment while contributing to important research in cancer care.

• • only supratentorial metastases allowed.
• • No radiotherapy for the central nervous system within 14 days prior to screening.
• • Untreated and Asymptomatic patients with brain metastasis brain metastases can be included in the study after judgment by the investigators, but regular brain imaging examinations of the disease site are required.
