Trial summary

Androgen Deprivation Therapy (ADT) triggers thymic revitalization and increases thymic output, enhancing baseline anti-tumor immunity and responses to immunotherapies. Anti-tumor synergism has been identified by combining ADT with anti-PD-1 immunotherapy for androgen-independent tumors. Read more about this study

About this study

Official title: A Clinical Investigation on the Efficacy of Leuprorelin Acetate (Androgen Deprivation Therapy) Combined With Sintilimab (Anti-PD-1) in Advanced Lung Cancer

Androgen Deprivation Therapy (ADT) triggers thymic revitalization and increases thymic output, enhancing baseline anti-tumor immunity and responses to immunotherapies. Anti-tumor synergism has been identified by combining ADT with anti-PD-1 immunotherapy for androgen-independent tumors. This study is to investigate the combination of Leuprorelin ADT and Sintilimab (anti-PD-1) therapy in patients with advanced lung cancer.

Read the detailed description

Immune checkpoint blockades (ICBs) are widely used in the clinical treatment of lung cancer. Studies have shown that the quantity and function of tumor-infiltrating lymphocytes (TILs) are associated with the effectiveness of PD-1 inhibitors in treating advanced NSCLC. The thymus is crucial for the differentiation, development, and maturation of T cells. With age, thymic atrophy leads to immunosenescence, significantly affecting baseline anti-tumor immunity and responses to immunotherapies. Preliminary findings have indicated that androgen deprivation therapy (ADT) not only directly induces apoptosis in prostate cancer cells but also may exert anti-tumor effects by promoting thymic regeneration. Furthermore, anti-tumor synergism has been identified by combining ADT with anti-PD-1 immunotherapy for androgen-independent tumors. Therefore, this study aims to investigate the combination of Leuprorelin ADT and Sintilimab (anti-PD-1) therapy in patients with advanced lung cancer.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants with Complete Response (CR)

    Disappearance of all target lesions, with nodular diseases excluded and target nodules reduced to <10mm in short axis.

    Measured: Efficacy evaluations are scheduled at 6 weeks,12 weeks and 18 weeks post treatment

  2. Number of Participants with Partial Response (PR)

    Reduction of at least 30% in the sum of diameters of all measurable target lesions compared to baseline

    Measured: Efficacy evaluations are scheduled at 6 weeks,12 weeks and 18 weeks post treatment

  3. Number of Participants with Disease Progression (PD)

    A 20% increase in the sum of the diameters of all measurable target lesions over the entire study period (using the smallest baseline value if it is the smallest), coupled with an absolute increase in the sum of diameters of at least 5mm. The appearance of one or more new lesions is also considered disease progression.

    Measured: Efficacy evaluations are scheduled at 6 weeks,12 weeks and 18 weeks post treatment

  4. Number of Participants with Stable Disease (SD)

    Lesion reduction not meeting PR criteria nor sufficient increase for PD, falling in between these two endpoints. The minimum sum of diameters during the study period can be used as a reference.

    Measured: Efficacy evaluations are scheduled at 6 weeks,12 weeks and 18 weeks post treatment

  5. Quantity of Peripheral Blood Lymphocytes

    Assessment of peripheral blood lymphocyte quantity, comparing patients before and after a treatment cycle

    Measured: Laboratory evaluations are scheduled before treatment, at 3 weeks post-treatment, and at 6 weeks post-treatment

  6. Composition of Peripheral Blood Lymphocytes

    Assessment of peripheral blood lymphocyte composition, comparing patients before and after a treatment cycle

    Measured: Laboratory evaluations are scheduled before treatment, at 3 weeks post-treatment, and at 6 weeks post-treatment.

  7. Status of Recent Thymic Emigrants (RTEs)

    Assessment of the status of Recent Thymic Emigrants (RTEs), comparing patients before and after a treatment cycle

    Measured: Evaluations are scheduled before treatment, at 3 weeks post-treatment, and at 6 weeks post-treatment.
