Knight Therapeutics Inc., (TSX: GUD) ("Knight") a pan-American (ex-USA) specialty pharmaceutical company, announced today that its Brazilian affiliate, United Medical Ltd., has received pricing approval for Minjuvi® (tafasitamab) from the Drugs Market Regulation Chamber ("CMED"). As a result, Knight expects to launch Minjuvi® in Brazil in the second quarter of 2024.

In July 2023, ANVISA (Agência Nacional de Vigilância Sanitária) granted Market Authorization under their rare disease designation according to Resolution RDC 205/2017 for Minjuvi® 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, and who are not eligible for autologous stem cell transplantation (ASCT).

Diffuse large B-cell lymphoma is a type of aggressive non-Hodgkin lymphoma, with suboptimal efficacy results with standard available therapies for patients who have failed to previous treatments and are not candidates for transplant.

"Considering the nature of the disease and the current unmet medical need, there is still space to improve the treatment of patients with relapsed or refractory diffuse large B-cell lymphoma in Brazil," said Dr. Danielle Leão, Head of the Hematology Department from Beneficência Portuguesa Hospital in São Paulo. "Minjuvi® is an innovative therapy with proven efficacy and safety profile. There is no other effective alternative approved in the country in the second line of treatment for relapsed or refractory DLBCL".

The approval is based on the data from L-MIND, an open label, multicenter, single arm Phase 2 study, that evaluated Minjuvi® in combination with lenalidomide for the treatment of adult patients with relapsed or refractory DLBCL. The study primary analysis results showed an objective response rate (ORR, primary endpoint) of 60%, including a complete response rate (CR) of 43% and a disease control rate (DCR) of 75%.

"We're excited to continue to advance the approval of Minjuvi® in Brazil, a new treatment option for a current unmet need. We look forward to launching Minjuvi® in Brazil and obtaining approval in other key markets in Latin America," said Samira Sakhia, Knight Therapeutics President and CEO.

In September 2021, Knight entered into a supply and distribution agreement with Incyte (NASDAQ: INCY), for the exclusive rights to distribute pemigatinib (Pemazyre®) as well as tafasitamab (sold as Monjuvi® in the United States and Minjuvi® in Europe) in Latin America.

With the price approval Minjuvi® will be available for commercialization in the Brazilian market. "Knight's team is working diligently with physicians, key institutions and payors to ensure patients have access to Minjuvi®," said Cristiane Coelho, Knight Therapeutics Brazil General Manager.

About Minjuvi® (tafasitamab)

Minjuvi® (tafasitamab) is a humanized Fc-modified cytolytic CD19 targeting immunotherapy. In 2010, MorphoSys licensed exclusive worldwide rights to develop and commercialize tafasitamab from Xencor, Inc. 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).

In the United States, Monjuvi® (tafasitamab-cxix) is approved by the U.S. Food and Drug Administration in combination with lenalidomide for the treatment of adult patients with relapsed or refractory DLBCL not otherwise specified, including DLBCL arising from low grade lymphoma, and who are not eligible for autologous stem cell transplantation (ASCT). This indication is approved under accelerated approval based on overall response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s). Please see the U.S. full Prescribing Information for Monjuvi for important safety information.

In Europe, Minjuvi® (tafasitamab) received conditional approval, 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).

Tafasitamab is being clinically investigated as a therapeutic option in B-cell malignancies in several ongoing combination trials. Its safety and efficacy for these investigational uses have not been established in pivotal trials.

Minjuvi® and Monjuvi® are registered trademarks of MorphoSys AG. Tafasitamab is co-marketed by Incyte and MorphoSys under the brand name Monjuvi® in the U.S., and marketed by Incyte under the brand name Minjuvi® in Region Europe, the United Kingdom and Canada. As part of its agreement with MorphoSys, Incyte received exclusive commercialization rights for tafasitamab outside the United States.

About Pemigatinib (Pemazyre®)

Pemigatinib is a kinase inhibitor indicated in the United States for the treatment of adults with previously treated, unresectable locally advanced or metastatic cholangiocarcinoma with a fibroblast growth factor receptor 2 (FGFR2) fusion or other rearrangement as detected by an FDA-approved test. This indication is approved under accelerated approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

The FDA approval in the USA is based on a multicenter, open-label, single-arm, multicohort, phase 2 study (FIGHT-202), that evaluated the safety and antitumor activity of pemigatinib in patients with previously treated, locally advanced or metastatic intrahepatic cholangiocarcinoma with and without FGFR2 fusions or rearrangements, in patients aged 18 years or older with disease progression following at least one previous treatment.

The overall response rate was 36%, with 2.8% of patients having a complete response and 34% having a partial response. Median duration of response was 9.1 months. The most common adverse reactions occurring in 20% or more of patients who received pemigatinib are hyperphosphatemia, alopecia, diarrhea, fatigue, dysgeusia, nausea and stomatitis.

Pemigatinib is also the first targeted treatment approved for use in the United States for treatment of adults with relapsed or refractory myeloid/lymphoid neoplasms (MLNs) with FGFR1 rearrangement.

In Japan, pemigatinib is approved for the treatment of patients with unresectable biliary tract cancer (BTC) with a fibroblast growth factor receptor 2 (FGFR2) fusion gene, worsening after cancer chemotherapy.

In Europe, pemigatinib is approved for the treatment of adults with locally advanced or metastatic cholangiocarcinoma with a fibroblast growth factor receptor 2 (FGFR2) fusion or rearrangement that have progressed after at least one prior line of systemic therapy.

Pemazyre® is marketed by Incyte in the United States, Europe and Japan.
