Study Overview

Status

Status

Completed

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

This is a dose-escalation study of Low-dose Radiation in combination with CS1001 in relapsed SCLC patients. Patients are assigned to 3 treatment groups received from 3 Gy to 15Gy, to determine the safety, tolerability and the maximal tolerant dose. Biomarkers and immunological markers are collected and analyzed as well.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). 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.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

  1. Patients with histologically or cytologically confirmed LS-SCLC or ES-SCLC and experienced progression since first-line standard platinum containing dual-drug chemotherapy.
  2. Patients whose initial diagnosis was limited must undergo radical chest radiotherapy and the time of tumor progression is not less than 3 months from the end of radiotherapy, or cannot receive radical chest radiotherapy due to specific reasons
  3. At least one extracranial measurable lesion (RECIST v1.1), and for a lesion that has received radiotherapy, progression of the lesion after radiotherapy must be confirmed.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
To determine the recommended radiation dose and preliminarily evaluate the anti-tumor efficacy of CS1001 in combination with low-dose radiotherapy in subjects with limited or extensive stage SCLC who failed the firstline treatment
Time Frame: From date of the first dose until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 2 years.
From date of the first dose until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 2 years.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Incidence of Adverse Events (AE) and Dose-Limiting Toxicity (DLT) as assessed by Common Terminology Criteria for Adverse Events (CTCAE) V4.03
Time Frame: From first dose to 30 days after last dose of CS1001, up to 2 years.
From first dose to 30 days after last dose of CS1001, up to 2 years.
Cmax: Peak concentration, the maximum drug concentration measured during one dosing cycle
Time Frame: From first dose to 30 days after last dose of CS1001, up to 2 years.
From first dose to 30 days after last dose of CS1001, up to 2 years.
The number and percentage of subjects with detectable Anti-drug Antibody (ADA)
Time Frame: From first dose to 30 days after last dose of CS1001, up to 2 years.
From first dose to 30 days after last dose of CS1001, up to 2 years.
