Knight entered into an exclusive supply and distribution agreement with Incyte (NASDAQ: INCY) in September 2021 for tafasitamab (commercialized as MONJUVI (tafasitamab-cxix) in the United States and MINJUVI ex-USA) across Latin America. Knight has launched MINJUVI in Brazil, Mexico and Argentina for use in combination with lenalidomide, followed by MINJUVI monotherapy, for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), who are not eligible for autologous stem cell transplantation (ASCT). In March 2026, Knight announced the approval and launch of MINJUVI in combination with rituximab and lenalidomide for the treatment of adult patients with relapsed or refractory FL in Brazil.1
"In past two years we have launched MINJUVI for the treatment of diffuse large B-cell lymphoma in Brazil, Mexico, and Argentina. More recently, MINJUVI received regulatory approval for the treatment of refractory follicular lymphoma in Brazil," said Samira Sakhia President and Chief Executive Officer of Knight Therapeutics. "We continue to advance our pipeline with the submissions for MINJUVI in both Argentina and Mexico. More importantly, MINJUVI is more than a single product. With approvals across distinct indications, it effectively represents multiple therapies within one brand, expanding the ways physicians can use MINJUVI to address different patient needs. I am proud of the progress we have made with MINJUVI and look forward to continuing our mission to bring high-quality pharmaceuticals that improve patients’ health in our markets."
About MINJUVI (tafasitamab)
MINJUVI (tafasitamab) is a humanized Fc-modified cytolytic CD19 targeting monoclonal antibody. Tafasitamab incorporates an XmAb engineered Fc domain, which mediates B-cell lysis through apoptosis and immune effector mechanism including Antibody-Dependent Cell-Mediated Cytotoxicity (ADCC) and Antibody-Dependent Cellular Phagocytosis (ADCP). Incyte licenses exclusive worldwide rights to develop and commercialize tafasitamab from Xencor, Inc.
In the U.S., MONJUVI is approved by the U.S. FDA in combination with lenalidomide and rituximab for the treatment of adult patients with relapsed or refractory follicular lymphoma (FL).
MONJUVI is not approved and is not recommended for the treatment of patients with relapsed or refractory marginal zone lymphoma outside of controlled clinical trials.
Additionally, MONJUVI received accelerated approval in the United States and Canada in combination with lenalidomide for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) not otherwise specified, including DLBCL arising from low grade lymphoma, and who are not eligible for autologous stem cell transplant (ASCT).
In Europe, MINJUVI (tafasitamab) received conditional Marketing Authorization from the European Medicines Agency in combination with lenalidomide, followed by MINJUVI monotherapy, for the treatment of adult patients with relapsed or refractory DLBCL who are not eligible for ASCT. Additionally, MINJUVI is approved in combination with lenalidomide and rituximab for the treatment of adult patients with relapsed or refractory follicular lymphoma (FL) (Grade 1-3a) after at least one line of systemic therapy in Europe.
In Japan, MINJUVI is approved in combination with rituximab and lenalidomide for adult patients with relapsed or refractory follicular lymphoma (2L+ FL).
In Brazil, MINJUVI is approved for use in combination with lenalidomide followed by MINJUVI monotherapy for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), including DLBCL arising from low grade lymphoma in Brazil, who are not eligible for autologous stem cell transplantation (ASCT) and is also approved in MINJUVI, in combination with rituximab and lenalidomide for the treatment of adult patients with relapsed or refractory follicular lymphoma (FL). MINJUVI is not approved and is not recommended for the treatment of patients with relapsed or refractory marginal zone lymphoma outside of controlled clinical trials.

About Follicular Lymphoma (FL)
FL is the most common subtype of indolent non-hodgkin lymphoma (NHL).2-4 FL typically presents with generalized painless lymphadenopathy that waxes and wanes. It commonly affects the axillary, cervical, femoral, and inguinal lymph nodes. Rarely, it may appear as an asymptomatic large mediastinal mass. Roughly 20% of FL patients experience B symptoms such as night sweats, fever, and weight loss.5 Although patients usually respond to initial therapy, FL will typically relapse over time and is therefore considered incurable.6,7 Approximately a quarter of FL patients are refractory to first-line immunochemotherapy.8 Additionally, there is a risk of histologic transformation to DLBCL or high-grade B-cell lymphomas, which occurs at an estimated annual rate of 2% to 3% and is generally associated with a poor clinical outcomes.9-12
About inMIND Study
The inMIND study (INCMOR 0208-301) was a Phase 3, randomized, double-blind, placebo-controlled, multicenter study in participants with relapsed/refractory FL or relapsed/refractory marginal zone lymphoma (MZL) who had been previously treated with at least one prior line of systemic therapy, including an anti-CD20 antibody. Patients were randomized to receive either tafasitamab + R2 (n = 273) versus placebo + R2 (n = 275). The estimated median progression free survival (PFS; primary endpoint) was 22.37 months (95% CI: 19.22, NE) in the tafasitamab + R2 group compared with 13.93 months (95% CI: 11.53, 16.39) in the placebo + R2 group, with a HR of 0.434 (95% CI: 0.324, 0.580) and a p < 0.0001. Overall, adding tafasitamab to lenalidomide plus rituximab led to a statistically significant, clinically meaningful improvement in PFS, corresponding to a 57% lower risk of progression, relapse, or death in patients with relapsed/refractory follicular lymphoma.13 The most common adverse reactions (≥ 20%) in patients with relapsed or refractory FL were respiratory tract infections, diarrhea, rash, fatigue, constipation, musculoskeletal pain, and cough. The most common Grade 3 or 4 laboratory abnormalities (≥ 20%) were decreased neutrophils and decreased lymphocytes.
