About this study

Official title: Safety and Efficacy of Sintilimab(S) in Combination With Histone Deacetylase Inhibitor (Chidamide, C) in Refractory and Relapsed (R) Angioimmunoblastic T-cell Lymphoma (AT): A Single-arm, Multicenter Phase II Study(SCRAT)

Angioimmunoblastic T-cell lymphoma (AITL) belongs to a subtype of peripheral T-cell lymphoma (PTCL) and is also a distinct type of non-Hodgkin lymphoma (NHL). The clinical outcomes of AITL is poor and optimal treatment strategies for AITL have not been fully defined. Patients with disseminated or relapsed disease have a very poor outcome, and there is no standard management for relapsed or refractory disease. Epigenetic drugs have been widely used to treat patients with refractory/relapse AITL. Several phase II clinical trails demonstrated the ORR of 33-50% in patients with r/r AITL treated with HDAC inhibitors (including Belimastat, Romidepsin, Chidamide). HDAC inhibitors are important drugs for the current treatment of AITL, but still more than half of the patients can not benefit from it. PD1/PD-L1 blockade was a potent strategy for r/r PTCL in two small sample studies. Current studies have found that HDACi can upregulate the expression of PDL1, In vivo testing of C57BL/6 mice revealed a synergistic tumor suppression after combining HDACi and PD-1 blockade. We carried out a single, open-label, multicenter clinical trial enrolled patients with relapsed/refractory AITL to investigate the safety and efficacy of sintilimab in combination with chidamide.

What is being measured

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

  1. Objective response rate (ORR), complete response rate (CRR), partial response rate (PRR)

    Assessed by the RECIL 2017 Response Criteria for Malignant Lymphoma

    Measured: Up to 24 months

Secondary outcomes (6)

  1. Progression-Free Survival (PFS)

    PFS is defined as the time from the treatment date to the date of disease progression per the RECIL 2017 Response Criteria for Malignant Lymphoma or death regardless of cause.

    Measured: Up to 24 months

  2. Overall Survival (OS)

    OS is defined as the time from treatment to the date of death.

    Measured: Up to 24 months

  3. Duration of Response (DOR)

    Among participants who experience an objective response, DOR is defined as the date of their first objective response (which is subsequently confirmed) to disease progression per the RECIL 2017 Response Criteria for Malignant Lymphoma or death regardless of cause.

    Measured: Up to 24 months

  4. Time to disease response (TTR)

    Among participants who experience an objective response, TTR is defined as the date of their first administration to the day of their first objective response (which is subsequently confirmed) per the RECIL 2017 Response Criteria for Malignant Lymphoma.

    Measured: Up to 24 months

  5. Time to progression (TTP)

    Among all participants, TTP is defined as the date of their first administration to the day of disease progression per the RECIL 2017 Response Criteria for Malignant Lymphoma or death regardless of cause.

    Measured: Up to 24 months

  6. The frequency of adverse events (adverse events, AEs) and serious adverse events (SAEs)

    An adverse event (AE) is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. TEAE were defined as AEs with onset during the treatment period or that are a consequence of a pre-existing condition that has worsened since baseline.

    Measured: Up to 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Sintilimab and Chidamide in people with Angioimmunoblastic T-cell Lymphoma, run by Sun Yat-sen University 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 13 inclusion and 26 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 5 Apr 2021. 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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective response rate (ORR), complete response rate (CRR), partial response rate (PRR) (time frame: 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 NCT04831710.

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 5 Apr 2021.
