NCT05502250

Brief Summary

This trial investigates the efficacy and safety of the drug tislelizumab in combination with chemotherapy as a treatment for patients with R/R HL. Tislelizumab is given in combination with chemotherapy (gemcitabine and cisplatin) followed by consolidation with tislelizumab alone. The study primary question is whether this strategy works as well as the standard treatment with intensive chemotherapy and autologous stem cell transplant.

Outcome Measures

Primary Outcomes (1)

  • Progression free survival (PFS) probability at 2 years after registration. PFS is defined as time from registration to progression or death from any cause, whichever comes first.

    Single-arm

    Approximately up to 48 months following first patient enrollment

Secondary Outcomes (8)

  • Overall response rate (ORR: mCR and mPR rates) (as assessed by FDG-PET/CT) after 2 and 4 cycles of tislelizumab in combination with GP chemotherapy induction.

    Approximately up to 28 months following first patient enrollment

  • Rate of CTCAE grade 3/4 toxicities of tislelizumab in combination with GP chemotherapy.

    Approximately up to 28 months following first patient enrollment

  • Rate of CTCAE grade 2 to 4 immune related toxicities of tislelizumab in combination with GP chemotherapy.

    Approximately up to 36 months following first patient enrollment

  • Rate of CTCAE grade 3/4 toxicities of tislelizumab consolidation treatment.

    Approximately up to 36 months following first patient enrollment

  • Progression free survival (PFS) as time-to-event outcome.

    Approximately up to 36 months following first patient enrollment

  • +3 more secondary outcomes

Study Arms (1)

Single-arm

EXPERIMENTAL

4 cycles of gemcitabine and cisplatin (GP) + tislelizumab followed by 13 cycles of tislelizumab

Drug: gemcitabine, cisplatin and tislelizumab

Interventions

All patients will receive 2 cycles of gemcitabine and cisplatin (GP) + tislelizumab. Each cycle lasts 21 days. Treatment is given through an IV line on day 1 and 8. After 2 cycles a FDG-PET-CT scan will be performed. Patients who respond well will proceed with 2 additional cycles of GP + tislelizumab . Patients with insufficient response will stop with the study treatment and they will continue treatment according to local practice. After 4 cycles of GP + tislelizumab another FDG-PET-CT scan will be performed. If this scan shows that the disease is under control (metabolic complete remission) patients will proceed with 13 cycles of tislelizumab consolidation treatment (21 day cycles). Treatment is given on day 1 through an IV line.

Single-arm

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically confirmed classical HL (according to the latest version of the WHO classification).
  • Primary refractory to first line chemotherapy, or in first relapse after any polychemotherapy regimen (e.g. ABVD, baseline BEACOPP or escalated BEACOPP, or other induction regimens).
  • In case of relapse, the relapse must be histologically confirmed. In case histologic biopsy is not possible, at least confirmation of the relapse by fine needle aspirate (FNA) or sequential imaging is required.
  • Measurable disease, based on Lugano criteria 2014 \[40\]; i.e. CT scans showing at least 2 or more clearly demarcated lesions with a long axis ≥ 1.5 cm and a short axis diameter ≥ 1.0 cm, or 1 clearly demarcated lesion with a long axis ≥ 2.0 cm and a short axis diameter ≥ 1.0 cm. These lesions must be FDG-PET-positive.
  • Age 18-70 years inclusive.
  • WHO/ECOG Performance Status ≤ 1 (see appendix C).
  • No major organ dysfunction, unless HL-related:
  • Total bilirubin \< 1.5x ULN (unless due to lymphoma involvement of the liver or a known history of Gilbert's syndrome; in that case bilirubin may be elevated up to 3 x ULN).
  • ALT/AST \< 3x ULN (unless due to lymphoma involvement of the liver; in that case ALT/AST may be elevated up to 5 x ULN).
  • GFR \> 60 ml/min as estimated by the Cockcroft\&Gault formula.
  • Adequate BM function defined as:
  • Absolute neutrophil count ≥ 1.5x109/L, unless caused by diffuse bone marrow infiltration by the HL.
  • Platelets ≥ 75 x109/L, unless caused by diffuse bone marrow infiltration by the HL.
  • Hemoglobin must be ≥ 8 g/dL (5 mmol/L).
  • Resolution of toxicities from first-line therapy.
  • +6 more criteria

You may not qualify if:

  • Previous treatment with an PD-1 or PDL-1 blocking agent.
  • Patients who have been using other investigational agents within at least 5 half lives or 4 weeks, whichever is longer, of the most recent agent used prior to start of protocol treatment.
  • Patients who were treated with myelosuppressive chemotherapy or biological therapy within at least 5 half lives or 4 weeks, whichever is longer, before start of protocol treatment.
  • Patients who were treated with steroids for more than 25 mg /day for at least 14 days before start of protocol treatment.
  • Patients receiving radiation therapy within 2 weeks prior to start of protocol treatment. Emergency radiation therapy is allowed, as long as measurable disease (at non-irradiated sites) persists.
  • Prior allogeneic stem cell transplantation or solid organ transplantation.
  • Peripheral neuropathy \> grade 2.
  • Active autoimmune diseases or history of autoimmune diseases that may relapse.
  • Note: Patients with the following diseases are not excluded and may proceed to further screening:
  • Controlled Type I diabetes.
  • Hypothyroidism (provided it is managed with hormone replacement therapy only).
  • Controlled celiac disease.
  • Skin diseases not requiring systemic treatment (eg, vitiligo, psoriasis, alopecia).
  • Any other auto-immune disease that is not expected to recur due to the protocol treatment.
  • Any condition that required systemic treatment with either corticosteroids (\> 10 mg daily of prednisone or equivalent) or other immunosuppressive medication ≤ 14 days before study treatment.
  • +17 more criteria
