Summary of treatment regimen

Patients with Early-stage Unfavourable Hodgkin Lymphoma (HL)
• 3 cycles of lead in Tislelizumab
• 4 total cycles Tis-CHOP or mini-CHOP
• Radiation Therapy (RT)

Patients with Advanced stage HL
• 3 cycles of Lead in Tislelizumab
• 6 total cycles of Tis-CHOP/mini-CHOP
• Patients whose response is classified a partial response can either receive RT OR receive 4 doses of Consolidation-Tislelizumab therapy starting 1-3 weeks after the PET-CT scan.

For patients who achieve a complete response (CR), the duration of systemic therapy will be for 21 weeks for early-stage HL or 27 weeks for advanced stage HL.

Patients will be followed for at least 2 years after end of treatment. All patients will be followed until the last patient has 2 years of follow-up post completion of treatment.


Detailed Treatment Plan
Optional pre-phase corticosteroid can be given after the screening PET-CT scan in those with very symptomatic HL. The dose can be up to 75mg of prednisone orally for up to 7 days and must be stopped at least 24 hours prior to tislelizumab.

Immunotherapy Lead In phase:
• Tislelizumab is given at 200mg intravenously (IV) on day 1
• Cycles are every 3 weeks for 3 cycles from cycle 1-3
• A PET-CT scan (PET-CT1) will be conducted 3-4 weeks after cycle 3, day 1 of the Tisleleluzimab lead in phase

Chemotherapy - Immunotherapy phase:
• This treatment phase will commence 4 - 5 weeks after cycle 3 day 1 of the lead in phase
• This treatment phase includes Tislelizumab and chemotherapy backbone of CHOP or mini-CHOP
• Cycles are every 21 days for 4-6 cycles, depending on the treatment stage eg advanced or early stage HL:
• Tislelizumab is given at 200mg intravenously (IV) on day 1
• The CHOP regimen is:
• Doxorubicin 50mg mg/m2 is given IV on day 1
• Vincristine 1.4mg/m2 (capped at 2mg) is given IV on day 1
• Cyclophosphamide 750mg/m2 is given IV on day 1
• Prednisone 40mg/m2 is given orally daily from day 1 to 5

• The mini-CHOP regimen is:
• Doxorubicin 25mg mg/m2 given IV on day 1
• Vincristine 1mg flat dose given IV on day 1
• Cyclophosphamide 400 mg/m2 given IV on day 1
• Prednisone 40mg/m2 given orally on days 1 to 5

For early stage patients, a final PET-CT scan is had at the end of the last treatment cycle to determine response

Immunotherapy Consolidation Phase:
• This treatment phase is only for those patients treated as advanced HL who are in a partial response on their end of treatment PET-CT.
• Tislelizumab 200mg is given IV on day 1
• Cycles are every 3 weeks for 4 cycles.
• A final PET-CT scan is had to determine response

Radiotherapy:
• For early-stage HL should be according to institutional guidelines
• For patients with advanced stage HL, radiotherapy is usually not indicated for those who have achieved a complete response. For those patients in a partial response, RT can be given according to investigator discretion, OR the patient can proceed to immunotherapy consolidation phase with Tislelizumab


Please note the following points:
• Mini-CHOP should be prescribed to all patients over the age of 80 at time of study registration.
• Patients aged 80 or less, should be prescribed CHOP if possible, however mini-CHOP can be prescribed provided there is a clearly documented reason that is communicated to the CI such as a high frailty score (6 or higher) or notable co-morbidities that the local investigator believes may preclude the use of full dose CHOP.
* Patients will be provided with dosing diaries to assist with compliance.

Outcomes
Primary outcome [1] 329582 0
The primary endpoint is complete metabolic response (CMR) of immunotherapy lead in with tislelizumab monotherapy in a dedicated treatment naïve elderly HL population. CMR will be assessed using a PET-CT scan.
Timepoint [1] 329582 0
This endpoint will be assessed when all patients have completed treatment and had their final PET-CT scan. Timing of the PET-CT scan is dependent on the patient's stage of disease and response, and will occur after the end of the last immunotherapy treatment cycle.
Primary outcome [2] 329583 0
The deliverability of immunotherapy lead in with tislelizumab monotherapy in a dedicated treatment naïve elderly HL population will also be assessed. This will be completed by reviewing physical exam and blood markers for adverse events and disease progression (composite primary outcome).
Timepoint [2] 329583 0
This endpoint will be assessed when all patients have completed or withdrawn from treatment.
Secondary outcome [1] 403101 0
The rate of adverse events (AE) will be calculated. AEs will be determined from blood markers and from the patients medical notes.
Timepoint [1] 403101 0
This outcome will be calculated when all patients have completed treatment. Adverse events will be collected at the patients standard of care visits from treatment commencement to 2 years after therapy completion.
Secondary outcome [2] 403102 0
The overall response rate (ORR) of Tisleluzimab monotherapy will be assessed. This will be completed using response data from the PET-CT scans.
Timepoint [2] 403102 0
This endpoint will be assessed when all patients have completed treatment and had their final PET-CT scan. Timing of the PET-CT scan is dependent on the patient's stage of disease and response, and will occur after the end of the last immunotherapy treatment cycle.
Secondary outcome [3] 403103 0
The CMR rate at the end of cycle 2 of the immunotherapy-chemotherapy phase will be assessed. PET-CT scan will be used to determine CMR.
Timepoint [3] 403103 0
This endpoint will be completed when all patients have completed all treatment.. Results will be taken from the PET-CT scan undertaken after the immunotherapy-chemotherapy phase.
Secondary outcome [4] 403107 0
The overall response rate (ORR) will be assessed at the end the immunotherapy and chemotherapy phases. ORR will be assessed using a PET-CT.
Timepoint [4] 403107 0
This endpoint will be analysed once all patients have completed treatment. Results will be taken from the PET-CT scan undertaken after the immunotherapy-chemotherapy phase.
Secondary outcome [5] 403108 0
Overall survival will be analysed using data from patient clinic visits.
Timepoint [5] 403108 0
This will calculated at 1 and 2 years after therapy completion.
Secondary outcome [6] 403109 0
Progression Free Survival will be calculated. This endpoint will use the PET-CT results to assess progression.

Summary
Brief summary
This study aims to assess the effect of Tislelizumab (an immunological treatment) in combination with CHOP or mini-CHOP (chemotherapy regimes) for the treatment of elderly patients with early- or advanced-stage Hodgkin Lymphoma.

Who is it for?
You may be eligible for this study if you are aged 61 years or older and have a diagnosis of stage IIA to IVB Hodgkin Lymphoma.

Study details
Participants who choose to participate in this clinical trial will receive 3 cycles (each cycle is 3 weeks) of intravenous Tislelizumab given on day 1 of the cycle. Four-5 weeks later, treatment with Tislelizumab will continue for another 4-6 cycles (each cycle is 21 days) in combination with CHOP or mini-CHOP, which is a lower-dose version of CHOP that may be given to patients over the age of 80 or who would not tolerate the full dose CHOP. This will be followed by a further four 3-week cycles of Tislelizumab, or may be followed by radiotherapy at the discretion of the investigator. For participants who achieve a complete response, the total duration of therapy will be for 21 weeks for those with early-stage disease or 27 weeks for those with advanced stage disease. All participants will be followed-up for a minimum of 2 years after the end of treatment, which will continue until the last patient has completed their 2-year follow-up. PET-CT scans will be used to monitor the response to treatment throughout, and any side effects of treatment will be monitored through regular physical examinations, blood tests, and a questionnaire.

It is hoped this research will determine whether Tislelizumab in combination with CHOP or mini-CHOP is effective and safe at treating Hodgkin Lymphoma in older patients, with tolerable toxicity.
