Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

At the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting, investigators reported that neoadjuvant camrelizumab combined with induction chemotherapy, followed by camrelizumab plus concurrent chemoradiotherapy and subsequent camrelizumab maintenance, achieved an overall response rate of 100 % in patients with locally advanced cervical cancer, with an acceptable safety profile.

Pre-clinical studies have suggested that concurrent chemoradiotherapy may dampen immune activation in cervical cancer, including reductions in the CD4+/CD8+ T-cell ratio and decreased T-cell receptor (TCR) diversity. These findings imply that administration of immunotherapy prior to chemoradiotherapy might be more effective than giving it concomitantly or afterwards.

Informed by these clinical and translational data, we propose to conduct an initial, prospective phase II trial to evaluate the efficacy and safety of neoadjuvant chemo-immunotherapy followed by concurrent chemoradiotherapy plus immunotherapy in patients with locally advanced cervical cancer, thereby laying the groundwork for a subsequent phase III investigation.

Phase

Phase

The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
