NCT04546620

Brief Summary

This study evaluates the addition of Acalabrutinib to current standard therapy of Rituximab, Cyclophosphamide, Doxorubicin, Vincristine and Prednisolone (R-CHOP) for patients with previously untreated CD20 positive Diffuse Large B-cell Lymphoma (DLBCL) requiring full course chemoimmunotherapy. All patients will receive one cycle of R-CHOP. Two thirds of patients (Arm B) will go on to receive a further 5 cycles (every 21 days) of R-CHOP with Acalabrutinib. Acalabrutinib will be taken orally twice daily continuously in 21 day cycles. One third of patients (Arm A) will continue with 5 cycles of R-CHOP. Patients will be followed up initially for 24 months and then for disease status and survival until 114 progression events have been observed.

Outcome Measures

Primary Outcomes (1)

  • To establish if combining acalabrutinib with R-CHOP improves efficacy, compared to RCHOP alone, for the treatment of previously untreated patients with DLBCL to a degree that justifies further development of this approach.

    Progression-free survival (PFS) is defined as time from registration to progression/death from any cause.

    Last patient's last follow up, approximately 4.5 years. Patients who do not experience a PFS event will be censored at the date of last follow up.

Secondary Outcomes (10)

  • To compare PFS between molecular groups.

    Last patient's last follow-up, approximately 4.5 years.

  • To compare PFS between treatment groups.

    Last patient's last follow-up, approximately 4.5 years.

  • To compare overall survival (OS) between both treatment and molecular groups.

    Last patient's last follow-up, approximately 4.5 years. Patients who do not experience an OS event will be censored at the date of last follow-up.

  • To compare event free survival (EFS) between both treatment and molecular groups.

    Last patient's last follow-up, approximately 4.5 years. Patients who do not experience an EFS event will be censored at the date of last follow-up.

  • To compare disease free survival (DFS) between both treatment and molecular groups.

    Last patient's last follow-up, approximately 4.5 years. Patients who do not experience a DFS event will be censored at the date of last follow-up.

  • +5 more secondary outcomes

Other Outcomes (5)

  • To explore correlation of molecular characteristics in tumour material to clinical outcomes.

    At baseline, cycle 2 day 1, cycle 3 day 1, end of treatment and at 3, 6, 9 and 12 month follow-ups. Each cycle is 21 days.

  • To explore correlation of baseline PET features including tumour burden and bone marrow involvement to clinical outcomes.

    Baseline and end of treatment (up to 21 weeks).

  • To explore combination(s) of clinical risk factors, molecular characteristics and PET features to clinical outcomes.

    Baseline and end of treatment (up to 21 weeks).

  • +2 more other outcomes

Study Arms (2)

Eligibility Criteria

Age16 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically confirmed DLBCL, expressing CD20. Sufficient diagnostic material must be available to forward to HMDS for gene expression profiling and central pathology review. The following diagnoses by 2016 WHO classification of lymphoid neoplasms may be included:
  • DLBCL, not otherwise specified (NOS)
  • T-cell/histiocyte-rich large B-cell lymphoma
  • Epstein-Barr virus positive DLBCL, NOS
  • ALK-positive large B-cell lymphoma
  • HHV8-positive DLBCL, NOS
  • High-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements (double-hit or triple-hit lymphoma)
  • High-grade B-cell lymphoma, NOS
  • At least one bi-dimensionally measurable lesion, defined as \>1.5 cm in its longest dimension as measured by CT.
  • Not previously treated for lymphoma and fit enough to receive combination chemoimmunotherapy with curative intent.
  • Stage IAX (bulk defined as lymph node mass \[either single or conglomerate\] diameter \>7.5cm) to stage IV disease and deemed to require a full course of chemotherapy. Patients with non-bulky IE disease will not be eligible.
  • ECOG performance status 0-2 or 3 if this is directly attributable to lymphoma.
  • Adequate bone marrow function with platelets \> 100x109/L; neutrophils \> 1.0x109/L at study entry, unless lower figures are attributable to lymphoma.
  • Measured or calculated creatinine clearance \> 30mls/min, (calculated using the formula of Cockcroft and Gault \[(140-Age) x Mass (kg) x (1.04 (for women) or 1.23 (for men))/Serum Creatinine (μmolL)\]).
  • Serum bilirubin \< 35μmol/L and transaminases \< 1.5x upper limit of normal at time of study entry.
  • +6 more criteria

You may not qualify if:

  • Previous history of treated or untreated indolent lymphoma. However newly diagnosed patients with DLBCL who are found to also have small cell infiltration of the bone marrow or other diagnostic material (discordant lymphoma) will be eligible.
  • Patients who have received immunisation with a live vaccine within four weeks prior to enrolment will be ineligible.
  • Diagnosis of primary mediastinal lymphoma.
  • Diagnosis of primary Central Nervous System lymphoma or secondary CNS involvement. Those patients presenting with neurological symptoms should be investigated for CNS involvement. Routine CNS imaging or diagnostic lumbar puncture will not be required in the absence of symptoms.
  • History of stroke or intracranial haemorrhage in preceding 6 months.
  • History of bleeding diathesis (eg, haemophilia, von Willebrand disease).
  • History of drug-specific hypersensitivity or anaphylaxis to any study drug (including active product or excipient components).
  • Requires or receiving anticoagulation with warfarin or equivalent antagonists (eg, phenprocoumon) within 7 days of first dose of acalabrutinib. However patients using therapeutic low molecule weight heparin or low dose aspirin will be eligible as will those receiving direct oral anticoagulants.
  • Prior exposure to an inhibitor in the BCR pathway (eg, Btk inhibitors, phosphoinositide-3 kinase (PI3K), or Syk inhibitors) or BCL-2 inhibitor (eg, ABT-199).
  • Requires treatment with a strong cytochrome P450 3A4 (CYP3A4) inhibitor/inducer.
  • Requires treatment with proton pump inhibitors (eg, omeprazole, esomeprazole, lansoprazole, dexlansoprazole, rabeprazole, or pantoprazole). Patients receiving proton pump inhibitors should switch to short-acting H2-receptor antagonists or antacids prior to the commencement of acalabrutinib, if randomised to receive acalabrutinib.
  • Active significant infection (e.g. progressive multifocal leukoencephalopathy (PML)).
  • Uncontrolled autoimmune haemolytic anaemia (AIHA) or idiopathic thrombocytopenic purpura (ITP).
  • Major surgery in the preceding 4 weeks of first dose of acalabrutinib (if applicable). If a subject had major surgery, they must have recovered adequately from any toxicity and/or complications from the intervention before the first dose of acalabrutinib (if applicable).
  • Corticosteroid use \>30 mg/day of prednisone or equivalent, for purposes other than for lymphoma symptom control. Patients receiving corticosteroid treatment with \<30 mg/day of prednisone or equivalent must be documented to be on a stable dose of at least 4 weeks' duration prior to the start of Cycle 1. If glucocorticoid treatment is urgently required for lymphoma symptom control prior to the start of study treatment, prednisone 100 mg or equivalent could be given for a maximum of 14 days as a prephase. A dose of up to 30mg or prednisolone or equivalent may be used during the screening phase to control symptoms.
