A Randomized, Double-Blind, Placebo-Controlled, Multi-Regional Phase III Clinical Study of Toripalimab Alone or in Combination With Tifcemalimab (JS004/TAB004) as Consolidation Therapy in Patients With Limited-Stage Small Cell Lung Cancer Without Disease Progression Following Chemoradiotherapy

Summary
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.
Eligibility
Inclusion Criteria8
- Male or female with age ≥ 18 years old at the time of informed consent.
- Histologically or cytologically confirmed LS-SCLC using the Veteran's Administration Lung Study Arm (VALSG) staging criteria (Appendix 3). Patients with TNM Stage I or II disease per AJCC 8th edition must be medically inoperable (as determined by the Investigator) or the patient must refuse surgery.
- Received CRT defined as: (1) 4 cycles of chemotherapy consisting of carboplatin or cisplatin and intravenously administered etoposide; (2) a total radiation dose of 60-66 Gy for the standard once daily (QD) radiotherapy regimen or 45 Gy for the hyperfractionated twice daily (BID) radiotherapy regimen; (3) Patients must begin investigational interventions within 42 days of the last dose of chemotherapy.
- Patients must have achieved a complete response (CR), partial response (PR), or stable disease (SD) after receiving curative platinum-based CRT and must not have developed progressive disease (PD) prior to study entry.
- Eastern Cooperative Oncology Group (ECOG) performance status (PS) score of 0-1 .
- Adequate organ function
- Female patients of childbearing potential and male patients whose partners are women of childbearing age.
- Voluntarily agree to participate in the study, sign the informed consent form, and agree to comply with all study and follow-up procedures.
Exclusion Criteria9
- Patients will be excluded from the study if they meet any of the following criteria.
- Mixed SCLC and non-small cell lung cancer (NSCLC).
- Received sequential chemoradiotherapy for LS-SCLC.
- Patients with active autoimmune disease, history of autoimmune disease.
- History of immunodeficiency, including HIV seropositivity, other acquired congenital immunodeficiency diseases, or a history of organ transplantation or allogeneic bone marrow transplantation.
- History of confirmed or suspected interstitial lung disease or pneumonitis (except for Grade 1 radiation pneumonitis not treated with corticosteroids).
- The presence of active hepatitis B (HBV DNA ≥ 500 IU/mL), hepatitis C (hepatitis C antibodies positive and HCV-RNA higher than the lower limit of detection of the analytical method).
- Any other malignancy diagnosed prior to the first dose of investigational intervention, except those with a low risk for the development of metastases (5-year survival rate \> 90%), such as adequately treated basal cell or squamous cell skin cancer, carcinoma in situ of the cervix or breast, or adequately treated localized prostate cancer.
- Women who are pregnant or breastfeeding.
