Response Adapted Incorporation of Tislelizumab Into the Front-line Treatment of Older Patients With Hodgkin lYmphoma
A Phase 2 study testing Tislelizumab, AVD, Radiotherapy in people with Hodgkin Lymphoma, run by University College, London.
Trial summary
The goal of this clinical trial is to test the effect of tislelizumab treatment in patients with Hodgkin lymphoma. The main question it aims to answer is whether including a drug called tislelizumab in first-line treatment of Hodgkin lymphoma for patients age 60 years and older is effective and well-tolerated.

About this study
Official title: Response Adapted Incorporation of Tislelizumab Into the Front-line Treatment of Older Patients With Hodgkin lYmphoma (RATiFY)
The goal of this clinical trial is to test the effect of tislelizumab treatment in patients with Hodgkin lymphoma. The main question it aims to answer is whether including a drug called tislelizumab in first-line treatment of Hodgkin lymphoma for patients age 60 years and older is effective and well-tolerated.
Participants will initially receive tislelizumab infusion every 21 days for 3 doses. After this a PET scan will be performed to assess the response. The subsequent treatment patients receive will depend on the following factors:
- The lymphoma stage (early stage or advanced stage)
- The presence or absence of specific high-risk features at the time of diagnosis
- How well the lymphoma responds to the initial 3 doses of tislelizumab
Read the detailed description
Trial patients who are deemed eligible for the trial will receive 3 cycles of tislelizumab which will be administered at a dose of 200 mg (IV) on day 1 of each 21-day cycle. Patients will then undergo a PET-CT scan (PET1). Subsequent treatment is determined by the patient's stage and response to tislelizumab (as determined by PET1).
Patients with early stage lymphoma and no high-risk features who respond very well to the initial 3 doses of tislelizumab will receive a further 2 doses of tislelizumab, followed by radiotherapy, followed by tislelizumab once every 21 days for up to 2 years.
All other patients will receive a combination of tislelizumab with chemotherapy for between 2 and 6 cycles. Each cycle will last 28 days. Tislelizumab will be given on day 1 and chemotherapy (doxorubicin (also known as Adriamycin), vinblastine and dacarbazine, or AVD) will be given on days 1 and 15, as injections or infusions into a vein. Following this some patients may require radiotherapy depending on their response to treatment.
Patients who are in complete metabolic response (CMR) at PET1 will receive 2 fewer cycles of tislelizumab and AVD therapy than those not in CMR.
A further 1 or 2 PET scans will be performed to assess how well the lymphoma has responded to the trial treatment, depending on the results of previous scans. After completing the treatment patients will then be followed-up for at least 2 years from the start of their participation in the trial.
Note: Initial patients will be recruited to a safety run in. Once 6 evaluable patients have completed 2 cycles of tislelizumab and AVD after PET1 the independent data monitoring committee (IDMC) will review the data, and if considered tolerable, recruitment will continue to the full sample size (80 patients).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Tislelizumab, AVD, Radiotherapy in people with Hodgkin Lymphoma, run by University College, London.
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 12 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: opening soon, as of the sponsor's last update on 29 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.
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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact RATiFY Trial Coordinator (+44 (0)2076799860, ctc.ratify@ucl.ac.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Two-year event-free survival (EFS) (time frame: 2 years after start of treatment). 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 29 Nov 2023; AzTrials last refreshed its copy on 8 Nov 2026.
