Immunotherapy Rechallenge in Patients with Solid Tumors in Clinical Trials

NCT ID: NCT06612632

Last Updated: 2024-09-25

Basic Information

• Recruitment Status: RECRUITING
• Clinical Phase: PHASE1/PHASE2
• Total Enrollment: 100 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2024-05-24
• Study Completion Date: 2028-06-30

Brief Summary

This study plans to include approximately 60-100 patients with advanced solid tumors who have progressed on clinical trial drugs. It will use an open-label, single-arm, multi-cohort umbrella design. In the first phase, patients who have progressed during treatment with novel tumor immunotherapy drugs will initially be targeted, combining or sequencing with PD-1 monoclonal antibody therapy. The inclusion criteria for frontline clinical trials are as follows: priority will be given to phase I clinical trials of novel immunotherapeutics as monotherapy, such as tumor vaccines, NK cell therapy, and new immune checkpoint inhibitors. Based on preliminary data, these have shown synergistic effects with PD-1/L1 monoclonal antibodies. In principle, the same investigational drug will only be used in either a combination or sequencing cohort. Subsequently, the study will expand to include patients who have progressed on other clinical trial treatments, combining or sequencing with other immune mechanism drugs.

Detailed Description

This study plans to include approximately 60-100 patients with advanced solid tumors who have progressed on clinical trial drugs, using an open-label, single-arm, multi-cohort umbrella design. In the first phase, patients who have progressed during treatment with novel tumor immunotherapy drugs will initially be targeted, combining or sequencing with PD-1 monoclonal antibody therapy. The selection criteria for frontline clinical trials are as follows: priority will be given to phase I clinical trials of novel immunotherapeutics as monotherapy, such as tumor vaccines, NK cell therapy, and new immune checkpoint inhibitors. Based on preliminary data, these have shown synergistic effects with PD-1/L1 monoclonal antibodies. In principle, the same investigational drug will only be used in either a combination or sequencing cohort. Subsequently, the study will expand to include patients who have progressed on other clinical trial treatments, combining or sequencing with other immune mechanism drugs.

Based on the interventions, the study is divided into combination therapy cohorts, sequential therapy cohorts, and real-world cohorts. The combination therapy cohorts will be further subdivided according to the investigational drug the patients received in the frontline setting: for instance, patients who have progressed on investigational drug A (e.g., SG1827) will receive drug A combined with PD-1 monoclonal antibody therapy (cohort A), and patients who have progressed on investigational drug B (e.g., ABO2011) will receive drug B combined with PD-1 monoclonal antibody therapy (cohort B), and so on. In the sequential therapy cohorts, regardless of the investigational drug used in the frontline setting, patients will receive PD-1 monoclonal antibody therapy. The real-world cohorts will include patients who do not meet the inclusion criteria for the aforementioned cohorts or refuse to participate in the interventional trials, with only subsequent treatment information, tumor progression, and overall survival being collected.

No specific sample size is predetermined for each cohort, and the study team may adjust the cohort sizes based on preliminary study results. In the combination therapy cohorts, the dosage and administration method of the investigational drugs will continue as per the patients' previous trial treatments. In both the combination and sequential therapy cohorts, the PD-1 monoclonal antibody will be administered at a fixed dose of 200 mg every 21 days or 3 mg/kg every 14 days. The treatments will continue until disease progression, death, or the occurrence of intolerable toxicity.

Eligibility Criteria

Inclusion Criteria

1. Recurrent or metastatic solid tumors confirmed by histopathology that cannot be treated with curative local therapy

2. Prior systemic anti-tumor treatment requirements: Previous first-line treatment involved a clinical trial of a new drug, with disease progression, and deemed by the investigator to no longer benefit from it

3. Suggested first dose administered within 12 weeks after the last treatment.

4. According to the RECIST 1.1 criteria, there should be at least one measurable lesion or more

5. ECOG PS 0-2 points

6. expected survival ≥ 3 months

7. as assessed by the investigator, major organ functions are good enough and can tolerate the experimental treatment regimen used in this study

8. subjects can understand and comply with the study procedures, sign the informed consent form, and voluntarily participate in this study

Exclusion Criteria

1. Previous exposure to immunotherapy (standard treatment or clinical trials) resulted in severe immune-related adverse events, as assessed by the investigator, making the re-administration of immunotherapy inappropriate.

2. Previous adverse reactions to advanced solid tumors have persisted, and the investigator anticipates these might impact the safety evaluation of the investigational drug

3. Previously experienced hyperprogression during immune therapy (conventional treatment or clinical trials), and the Other conditions deemed unsuitable for participation in this study by the investigator believes that no further benefit can be gained from this study. Criteria include: (1) Tumor progression time less than two months during immunotherapy

4. (2) Tumor burden increased by over 50% compared to baseline

5. (3) Tumor growth rate post-immunotherapy exceeds twice the previous rate

6. Central nervous system metastases or leptomeningeal metastases with clinical symptoms

7. During the screening period, subjects are determined by the investigator to have severe or uncontrolled underlying diseases (such as hypertension, diabetes, cardiovascular diseases, pulmonary diseases, autoimmune diseases, etc.)

8. Received other anti-tumor therapy between the last front-line therapy and the first dose of the study drug

9. Other conditions deemed unsuitable for participation in this study by the investigator

• Minimum Eligible Age: 18 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
