  • Be willing and able to provide written informed consent/assent for the trial.
  • Be 18 years of age on day of signing informed consent.
  • Be willing to provide tissue from a newly obtained core or excisional biopsy of a tumor lesion. Newly-obtained is defined as a specimen obtained up to 6 weeks (42 days) prior to initiation of treatment on Day 1.

  • Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication. Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year.
  • Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy.

Who cannot join

  • Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment.

About this study

Official title: PD-1 Blockade With Pembrolizumab in Relapsed/Refractory Mature T-cell and NK-cell Lymphomas

Conventional chemotherapeutic regimens designed for aggressive B-cell lymphomas are generally less effective when applied to mature T-cell or NK-cell lymphomas. The treatment outcome for relapsed or refractory disease is especially poor.

This is a single centre, prospective, non-randomized, open-label, phase II study to evaluate the efficacy of pembrolizumab in patients with relapsed or refractory mature T-cell or NK-cell lymphomas. Patients will receive pembrolizumab 200mg i.v. once every 3 weeks until disease progression or unacceptable toxicity.

A baseline radiological assessment by positron emission tomography / computed tomography (PET/CT) scan is obtained before commencement of treatment. Tumor response and progression are evaluated by physical examination, standard laboratory tests, and PET/CT scan according to standard criteria. Standard response criteria for non-Hodgkin lymphomas are used for assessment . PET/CT scan will be done at week 12, week 24, week 36 and every 18 weeks thereafter.

Read the detailed description

Pembrolizumab is a potent and highly selective humanized monoclonal antibody (mAb) of the IgG4/kappa isotype against PD-1, designed to directly block its interaction with PD-L1 and PD-L2. KeytrudaTM (pembrolizumab) has recently been approved in the United Stated for the treatment of melanoma that is unresectable or metastatic, or has progressed following ipilumumab and, (if BRAF V600 mutation positive), a BRAF inhibitor.

Mature T-cell and nature killer (NK)-cell lymphomas are lymphoid malignancies that are derived from T-cell and NK-cell lineages. They are less prevalent than B-cell lymphomas. Interestingly, there are distinct geographic differences in their distribution and prevalence. Nodal lymphomas including peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS), angioimmunoblastic T-cell lymphoma (AITL), anaplastic large cell lymphoma (ALCL) and cutaneous T-cell lymphomas (CTCL) predominate in Western populations, accounting for about 10% of all lymphomas. In Asian countries, however, extranodal NK/T-cell lymphoma, nasal type, is much more prevalent, constituting 10% of all lymphomas; with AITL, ALCL and PTCL-NOS accounting for another 10%. Epstein Barr virus (EBV) infection is found in all cases of extranodal NK/T-cell lymphomas, the majority of AITL, and a significant proportion of PTCL-NOS, implying that it plays an important pathogenetic role.

Conventional chemotherapeutic regimens designed for aggressive B-cell lymphomas are generally less effective when applied to mature T-cell or NK-cell lymphomas. The treatment outcome for relapsed or refractory disease is especially poor. In a recent retrospective analysis, the median overall survival (OS) and progression-free survival (PFS) in patients with disease relapse were found to be only 5.5 and 3.1 months respectively. The efficacy of newly approved agents such as pralatrexate and romidepsin for relapsed or refractory T-cell lymphomas is modest, with an average overall response rate (ORR) of around 20-30% only. Novel therapeutic approaches are therefore needed for this group of patients with dismal prognosis.

PD-1 blockade using anti-PD1 monoclonal antibody has been shown to be highly effective for relapsed/refractory classical Hodgkin lymphoma. Furthermore, clinical response has also been seen in relapsed T-cell lymphomas after treatment with anti-PD-1 antibody in phase I studies. In addition, previous reports have shown that EBV infection may enhance the expression of PD-L1 in tumour cells, and that some EBV-associated lymphomas such as NK/T-cell lymphoma express high level of PD-L1, suggesting that EBV-associated mature T-cell and NK-cell lymphomas may be more susceptible to PD-1 blockade.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing pembrolizumab in people with T-Cell Lymphoma and NK-Cell Lymphoma, run by The University of Hong Kong at 1 site in Hong Kong.

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 8 inclusion and 21 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 17 Apr 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 Hong Kong. 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 Eric Tse, PhD(Cantab) (85222554361, ewctse@hku.hk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Complete remission rate (CR) (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 17 Apr 2019.
