A Study of TAK-981 in Combination with Rituximab in Participants with Relapsed/Refractory (r/r) CD20-positive (CD20+) Non-Hodgkin Lymphoma (NHL)


About this study

The purpose of this study is to determine the safety and tolerability of TAK-981 in combination with rituximab in participants with r/r CD20+ NHL in Phase 1b, and to evaluate the effectiveness of TAK-981 in combination with rituximab in r/r CD20+ NHL in Phase 2.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

Each participant must meet all the following inclusion criteria to be enrolled in the

1. Participant Population:

o. For Phase 1 Dose Escalation: o. aNHL including mantle cell lymphoma and DLBCL
histologies such as transformed DLBCL from low-grade lymphoma (follicular or others),
DLBCL associated with small-cell infiltration in bone marrow, B-cell lymphoma with
intermediate features between DLBCL and Burkitt's lymphoma or with intermediate
features between DLBCL and Hodgkin lymphoma, FL grade 3B, and aggressive B-cell
lymphoma unclassifiable who must have previously received rituximab, cyclophosphamide,
doxorubicin (hydroxydaunorubicin), vincristine, (Oncovin) and prednisone (R-CHOP) (or
equivalent anti-CD20 containing therapy) and 1 additional line of therapy in the r/r

o. iNHL (including FL of grades 1-3A and marginal zone lymphoma) refractory to
rituximab or to any other anti-CD20 monoclonal antibodies, who have received at least
1 prior systemic therapy for r/r iNHL.

o. Rituximab or anti-CD20 refractoriness is defined as failure to respond to, or
progression during, any previous rituximab/anti-CD20-containing regimen (monotherapy
or combined with chemotherapy), or progression within 6 months of the last rituximab
or anti-CD20 dose.

Note: The minimum qualifying rituximab/anti-CD20 dose is 1 full cycle (that is,
weekly*4 doses monotherapy or 1 complete dose if combined with chemotherapy). Prior
anti-CD20 antibody or cytotoxic drugs may have been administered as single agents or
as components of combination therapies. Each repeated course of the same single-agent
or combination is considered an independent regimen.

o. For Phase 2, the following confirmed CD20+: o. r/r DLBCL progressed or relapsed
after a prior CAR T-cells therapy that has received approval by a health authority for
the treatment of DLBCL (Cohort A).

o. r/r DLBCL that has progressed or relapsed after at least 2 but no more than 3 prior
lines of systemic therapy and has not I prior cellular therapy. At least one prior
line of therapy must have included a CD20-targeted therapy (Cohort B).

o. r/r FL that has progressed or relapsed after at least 2 but no more than 3 prior
lines of systemic therapy. At least 1 prior line of therapy must have included a
CD20-targeted therapy (Cohort C).

2. Must be considered ineligible in the opinion of the investigator, or refused
autologous stem-cell transplantation (ASCT).

3. Eastern Cooperative Oncology Group (ECOG) performance score of less than or equal to
(<=) 2.

4. Adequate bone marrow function per local laboratory reference range at screening as

o Platelet count greater than or equal to (>=) 75.0*10^9/L, Grade 2 thrombocytopenia
(platelet count >=50.0*10^9 per liter [/L]) is allowed if it is clearly due to marrow
involvement with no evidence of myelodysplastic syndrome or hypoplastic bone marrow if
found. Absolute neutrophil count (ANC) >=1.0*10^9/L. Hemoglobin >=85 gram per liter
(g/L) (red blood cell [RBC] transfusion allowed >=14 days before assessment).

5. Adequate renal and hepatic function, per local laboratory reference range at screening
as follows:

- Calculated creatinine clearance >=30 milliliter per minute (mL/min) calculated
with Cockcroft-Gault formula.

- Potassium levels >=lower limit of normal (LLN). For potassium >upper limit of
normal (ULN) discussion with Takeda medical monitor (MM)/designee recommended.

- Aspartate aminotransferase and alanine aminotransferase <=3.0*the ULN of the
institution's normal range; bilirubin <=1.5*ULN. Participants with Gilbert's
syndrome may have a bilirubin level >1.5*ULN, per discussion between the
investigator and the medical monitor.

6. Left ventricular ejection fraction (LVEF) >=40 percent (%); as measured by
echocardiogram or multiple gated acquisition (MUGA) scan.

7. Suitable venous access for safe drug administration and the study-required PK and
pharmacodynamic sampling.

8. Have at least 1 bidimensionally measurable lesion per Lugano Classification by
computed tomography (CT). Tumor lesions situated in a previously irradiated area are
considered measurable if progression has been demonstrated in such lesions.

9. Willing to consent to 1 mandatory pretreatment and 1 on-treatment skin biopsy during
Phase 1. The skin biopsy entry requirement may be discontinued by the sponsor once
there is enough pharmacodynamic evidence of target engagement.

10. For participants enrolled in Phase 2, if available, mandatory submission of archival
tumor tissue acquired ≤12 months prior to screening.

11. Recovered to Grade 1, baseline or established as sequela, from all toxic effects of
previous therapy (except alopecia, neuropathy, autoimmune endocrinopathies with stable
endocrine replacement therapy, neurotoxicity [Grade 1 or 2 permitted], or bone marrow
parameters [any of Grade 1, 2, permitted if directly related to bone marrow
