A Real-World Study of Toripalimab in Chinese Patients With Lung Cancer(THUNDER Study)

Study Overview
=================
Brief Summary
-----------------
Our project is going to clarify the efficacy and safety of Toripalimab in lung cancer in the real world, and to evaluate the incidence of adverse events (AEs) of special interest during Toripalimab immunotherapy.

Detailed Description
-----------------
Tumor immunotherapy, as another important treatment after surgical treatment, chemoradiotherapy and targeted therapy, has achieved great success and gradually become one of the standard treatment methods for tumors. Toripalimab is the first Chinese PD-1 inhibitor approved for the treatment of nasopharyngeal carcinoma, malignant melanoma, urothelial carcinoma, esophageal squamous cell carcinoma and non-small cell lung cancer. It has been widely used in clinical practice. Several clinical studies have confirmed that it is safe and effective. In recent years, several clinical studies have reported that Toripalimab alone or in combination can improve the response rate of cancer treatment and improve survival. The results of Toripalimab research are mainly derived from rigorously designed randomized controlled trials (RCTs), and the efficacy and safety in the real world still need to be further explored. Real world studies, based on a large sample size, non-randomly select treatment measures according to the actual condition and wishes of patients, and pay attention to meaningful outcome treatment, which is closer to real clinical practice, without extrapolation difficulties, and has more clinical practical value. Therefore, it is of great significance to carry out a real-world study to investigate the differences in the efficacy and adverse reactions of Toripalimab immunotherapy in Chinese lung cancer patients in order to better guide clinical practice, which also provides research direction and data support for further prospective studies.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Immunotherapy Regimen<br>Patients receiving different treatment regimens of Toripalimab in each center were consecutively enrolled from January 1, 2019 to December 31, 2022 | Drug: Toripalimab<br>* Toripalimab injection, recommended dose is 3 mg/kg, intravenous infusion every 2 weeks or 240 mg fixed dose, intravenous infusion every 3 weeks. Other treatment options are individualized according to the diagnosis and treatment experience of doctors in each center, diagnosis and treatment specifications and individual conditions of patients.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall survival(OS) | OS was calculated from the date of randomization to death from any cause. | 2 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression Free Survival(PFS) | PFS was defined as the time from the first day of study treatment to the first documented disease progression per irRC or death due to any cause, whichever occurred first. | 2 years | 
| Overall Response Rate (ORR) | ORR was defined as the percentage of participants in the analysis population who had a Complete Response (CR; disappearance of all target lesions) or Partial Response (PR; at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters). | 1 year | 
| Disease Control Rate(DCR) | The percentage of cases with remission (PR + CR) and stable lesions (SD) after treatment was assessable. | 1 year | 
| Health-related quality of life (HRQoL) | HRQoL measured by standardized EORTC questionaires (EORTC QLQ-C30) | Within 1 year after starting Toripalimab treatment |
