Brief Summary:
NCCN guidelines for B cell lymphoma suggest that patients with relapsed/refractory aggressive NHL who are candidate for high-dose therapy should receive combination of cytotoxic chemotherapies as 2nd line treatment. However, proportion of patients who are adequately salvaged by second line chemotherapy and high-dose chemotherapy with stem cell rescue is unsatisfactory. Moreover, many fragile patients are unfit for salvage cytotoxic chemotherapy and/or high-dose chemotherapy. Hence, most of patients with relapsed/refractory aggressive B-cell NHL is ultimately candidate for less-cytotoxic drugs with targeted approach. This trial is phase II trial of acalabrutinib in combination with rituximab and lenalidomide for these patients.

Arm Intervention/treatment
Experimental: Treatment arm

Acalabrutinib is provided as hard gelatin capsules for oral administration. Acalabrutinib 100 mg will be administered approximately every 12 hours from day 1 to day 28 Rituximab is provided as single-use vials for intravenous administration only. Rituximab 375 mg/m2 will be administered on day 1.

Lenalidomide is provided as opaque hard capsules for oral administration. Lenalidomide 20 mg will be administered once daily from day 1 to day 21

Drug: Acalabrutinib

Acalabrutinib, lenalidomide, rituximab will be given as described in the "Arms" decriptions. Day 1 to day 28 is considered one cycle, and cycles will be repeated every 4-weeks, for 6 cycles.

After 6 cycles, maintenance of acalabrutinib 100mg bid will be administered up to 1 year for subjects whose best responses- to the regimen are partial response or complete remission.

Other Names:
  • Lenalidomide
  • Rituximab

Primary Outcome Measures :
  1. Objective Response Rate (ORR) [ Time Frame: within 4 weeks after the 6 cycles of combination therapy (each cycle is 28 days) ]
    ORR is defined as the percentage of subjects with evidence of a confirmed complete response (CR) or partial response (PR) as per Lugano criteria

Secondary Outcome Measures :
  1. Duration of response [ Time Frame: Tumor status will be assessed at Week 8, 16, 24 (± 7 days), then every 3 months (± 14 days) ]
  2. Complete remission rate [ Time Frame: Response will be assessed at Week 8, 16, 24 (± 7 days) ]
  3. Progression free survival [ Time Frame: Tumor status will be assessed at Week 8, 16, 24 (± 7 days), then every 3 months (± 14 days) ]
  4. Overall survival [ Time Frame: Tumor status will be assessed at Week 8, 16, 24 (± 7 days), then every 3 months (± 14 days) ]

Urine hCG test must be done 4 weeks after the last dose of acalabrutinib, lenalidomide and rituximab.
