A Prospective, Multicenter Exploratory Clinical Study on Consolidation Therapy With Tislelizumab Combined With Nintedanib for Limited-stage Small Cell Lung Cancer

This study is a prospective, single-arm, multicenter, exploratory clinical trial. It aims to evaluate the efficacy and safety of tislelizumab combined with nintedanib as consolidation therapy for patients with limited-stage small cell lung cancer after concurrent chemoradiotherapy, and to explore the prognostic markers related to the therapeutic effect.

Concurrent Chemoradiotherapy Combined With Toripalimab and Surufatinib in the Treatment of Limited-Stage Small Cell Lung Cancer

Based on the preclinical rationale for combining surufatinib with immunotherapy, and the clinical efficacy observed with surufatinib in extensive-stage small cell lung cancer (ES-SCLC), the investigators hypothesize that incorporating surufatinib into the ADRIATIC regimen could further enhance survival in LS-SCLC. To evaluate this approach, the investigators plan to conduct a single-arm Phase II study to explore the safety and efficacy of concurrent chemoradiotherapy combined with toripalimab and surufatinib in treating LS-SCLC.

A Study of QL1706 Combined With Chemotherapy Induction on Sequential Immunotherapy Consolidation in Patients With Limited-Stage Small Cell Lung Cancer After Chemoradiotherapy

The study is being conducted to evaluation of the Efficacy and Safety of QL1706 Combined with Chemotherapy Induction in Sequential Immunotherapy Consolidation After Concurrent Chemoradiotherapy for Limited-Stage Small Cell Lung Cancer(LS-SCLC), and Exploration of the Correlation Between Biomarkers (PD-L1, TMB, ctDNA, etc.) Related to QL1706 Treatment and Treatment Efficacy and Prognosis. QL1706 (Iparomlimab and Tuvonralimab) is a single bifunctional MabPair product against PD-1 and CTLA-4. QL1604 is a monoclonal antibody against PD-1.

Hypofractionated Radiotherapy Followed by Chemo-immunotherapy Induction Therapy

Radiotherapy can activate local and systemic immune responses through a variety of mechanisms, which can enhance anti-tumor immune effects. The dose fractionation pattern of radiotherapy has an important influence on the occurrence of immune-induced effects. Stereotactic body radiation therapy (SBRT) has obvious advantages in activating interferon effects and inducing abscopal effects. SBRT combined with immunity can enhance the abscopal effect induced by radiotherapy and play a synergistic role. The 8Gy×3 fractionation scheme is currently the most widely used stereotactic radiotherapy scheme. Because we conducted this study, the primary lesion received large-fraction partial tumor irradiation and then received adebrelimab combined with chemotherapy induction treatment for 2 cycles, followed by sequential chest radiotherapy for the treatment of limited-stage small cell lung cancer, to explore the effectiveness and safety.

Prediction of Response to PD-L1 Inhibitor After Chemoradiotherapy in Limited-Stage Small-Cell Lung Cancer Using Multi-omics-based Liquid Biopsy

This study aims to explore the efficacy and safety of immunotherapy (PD-L1 inhibitor) maintenance following high-dose hyperfractionated simultaneous integrated boost radiotherapy concurrent chemotherapy in patients with limited-stage small cell lung cancer (LS-SCLC). This study is a prospective observational study. Additionally, liquid biopsy technology will be employed to identify biomarkers that can predict the efficacy of PD-L1 inhibitor after chemoradiotherapy in LS-SCLC.

Adjuvant Adebrelimab Plus Apatinib After Chemoradiation in Limited-Stage Small Cell Lung Cancer

The study includes the screening period (from the time the subject signs the informed consent form to no more than 28 days before the first dose, imaging evaluations are allowed within 28 days before the first dose, and 5-14 days after the last radiotherapy/chemotherapy treatment, as close as possible to the treatment start date and the start of the study treatment), tumor tissue biopsy collection based on the subject's hospital, with preferred samples obtained within ≤3 months, but archived samples within 6 months before the first dose are also acceptable. The treatment period (until disease progression/worsening or confirmed radiological disease progression, or withdrawal for any reason) and the follow-up period (from the last dose to 36 months, including safety follow-up and survival follow-up). \*\*Screening Period:\*\* Subjects who have received 2-4 cycles of platinum-based concurrent or induction chemotherapy (cCRT) and are evaluated as having non-progressive disease after cCRT, with the cCRT treatment ending within 1-42 days before the first dose, and the last radiotherapy session as the final end time. Consolidation chemotherapy after radiotherapy is not allowed. Screening evaluation must be performed within 28 days before the first dose to determine eligibility. Tumor tissue samples should be collected based on the subject's hospital. The preferred samples are archived or freshly obtained tumor tissue wax blocks or pathological biopsy slides within ≤3 months, but archived samples within 6 months before the first dose are also acceptable. \*\*Treatment Period:\*\* Each treatment cycle is 3 weeks. Atezolizumab 1200mg is administered via intravenous infusion, and Apatinib 250mg is taken orally after meals, once daily, for continuous use. Subjects must undergo a comprehensive examination at the end of the study treatment or when withdrawing from the study, including vital signs, physical examination, laboratory tests, quality of life assessment, clinical tumor imaging evaluation (CT or MRI), and other necessary checks. \*\*Follow-up Period:\*\* After the study treatment ends or the subject withdraws from the study, safety follow-up should be conducted. Subjects should be followed up every 30±7 days until 90 days. The first (30±7 days after withdrawal from the group) safety visit must be conducted at the research center, and vital signs, physical examination, laboratory tests, etc., should be assessed for AEs, concomitant medications, and supportive treatments. The other two visits (60±7 days and 90±7 days after withdrawal from the group) will be conducted by telephone, collecting survival information, AEs, concomitant medications, and supportive treatments. After the safety follow-up is completed, subjects will be followed up every 3 months by phone to monitor survival status until death, loss to follow-up, withdrawal of informed consent, observation for 3 years, or termination of the study.

Phase 3 Study of Toripalimab Alone or in Combination With Tifcemalimab as Consolidation Therapy in Patients With Limited-stage Small Cell Lung Cancer (LS-SCLC)

The Study is a Phase 3, randomized, three-arm, double-blind, placebo-controlled, multi-regional clinical research study to evaluate the safety and efficacy use of toripalimab alone or in combination with tifcemalimab as consolidation therapy in patients with limited-stage small cell lung cancer without disease progression following chemoradiotherapy. Tifcemalimab is a monoclonal antibody against B and T lymphocyte attenuator (BTLA). Toripalimab is a monoclonal antibody against programmed death protein-1 (PD-1). Neither drug is approved for treatment of This combination regimen is investigational in limited stage-small cell lung cancer in any country.
