About this study

Official title: An Open-Label Single-Arm Phase Ⅱ Study to Evaluate Efficacy and Safety of Sintilimab Combined With Metformin Hydrochloride in Patients With Advanced Non-small Cell Lung Cancer Refractory to First-Line Treatment

Evaluate the Efficacy and Safety of Sintilimab Combined with Metformin Hydrochloride in Patients with Advanced Non-small Cell Lung Cancer Refractory to First-Line Platinum-Containing Chemotherapy

Read the detailed description

This study is an open-label, single-arm, phase II clinical study on the efficacy and safety of Sintilimab combined with metformin in the treatment of locally advanced, recurrent or metastatic NSCLC patients who fail to receive first-line platinum-containing chemotherapy in patients with locally advanced, recurrent or metastatic non-small-cell lung cancer in China. Simon two stages optimal design criteria are used in the test, and 18 subjects are enrolled in the first stage, and if two or more patients reach the PR/CR evaluation criteria, the sample size will be increased to 43. If 7 or more of the 43 subjects meets the PR/CR evaluation criteria, it indicates that the test achieves the expected results. After the subject signs the informed consent, the subject will receive the treatment of 200 mg IV Q3W (3 weeks using a) of Sintilimab combine with 500mg of metformin for oral bid until disease progression, death, toxicity intolerance, withdrawal of the informed consent, initiation of new anti-tumor treatment or termination of treatment for other reasons specified in the program. The longest duration of treatment for Sintilimab is 24 months. The main endpoint of the study is ORR evaluated by the researchers based on RECIST v1.1.

RECIST v1.1 is used for clinical tumor imaging evaluation. Based on the clinical conditions of the patients, it is used every 2 cycles (±7 days) until disease progression, initiation of new anti-tumor therapy, withdrawal of Inform Consent Form (ICF) or death of the subjects. For the first time, if the clinical status of the subjects with disease progression is stable, those who meet the criteria determined by the investigator can continue to receive treatment of Sintilimab combined with metformin, and must undergo imaging evaluation after 4 weeks (± 7 days) to confirm the disease progression. Patients with disease progression will enter the survival follow-up stage (every 60 ± 7 days); Patients who stop treatment due to other causes other than disease progression will continue to receive the tumor assessment every 6 weeks (± 7 days) until the next event (initiation of new anti-tumor treatment, disease progression, withdrawal of ICF or death), and then enter the survival follow-up stage (every 60 ± 7 days).

The investigator will evaluate and manage the adverse reactions during the treatment period and within 30 ± 7 days after the last use of the study drug in accordance with the NCI Common Terminology Criteria for Adverse Events (CTCAE) 4.0 and immune-related adverse reactions standard Immune-Related Response Criteria (irRC), evaluation and management of severe adverse reactions during the treatment period and 90 ± 7 days after the last use of the study drug (unless patients start new anti-tumor treatment 31 to 90 days after the last use of the study drug).

What is being measured

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

  1. Objective Response Rate (ORR)

    ORR is defined as participants who had complete response (CR) or partial response(PR) divided by the total number of patients.

    Measured: each 42 days up to intolerance the toxicity or PD (up to 24 months)

Secondary outcomes (4)

  1. Overall Survival (OS)

    OS is defined as time from date of enrollment to date of death due to any cause. For participants still alive at the time of analysis, OS time was censored on last date that participants were known to be alive.

    Measured: From enrollment until death (up to 24 months)

  2. Progress free survival (PFS）

    The PFS time is defined as time from enrollment to locoregional or systemic recurrence, second malignancy or death due to any cause; censored observations will be the last date of : "death", "last tumor assessment", "last follow up date" or "last date in drug log"

    Measured: each 42 days up to PD or death (up to 24 months)

  3. Disease Control Rate (DCR）

    DCR is defined as the percentage of participants with Disease Control best overall response (complete response, partial response or stable disease).

    Measured: each 42 days up to intolerance the toxicity or PD (up to 24 months)

  4. Duration of Response (DOR)

    For participants with response (CR or PR), the duration of response: the time from the first response date to disease progression or death, and the date of the final imaging evaluation was deleted for participants without PD or death.

    Measured: From the first response date to PD or death (up to 24 months)

What is this clinical trial studying?

A Phase 2 study testing Sintilimab and Metformin Hydrochloride in people with Non Small Cell Lung Cancer, run by Tianjin Medical University Cancer Institute and Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 19 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Dingzhi Huang, M.D. (+86 18622221232, dingzhih72@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective Response Rate (ORR) (time frame: each 42 days up to intolerance the toxicity or PD (up to 24 months)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03874000, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Mar 2019.
