Knight Therapeutics Announces Launch of Minjuvi® in Brazil

Knight Therapeutics Inc., (TSX: GUD) ("Knight"), a pan-American (ex-USA) specialty pharmaceutical company, announced today the launch of Minjuvi ® (tafasitamab) by its Brazilian affiliate, United Medical Ltda. Minjuvi ® is indicated 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 transplant (ASCT).

DLBCL, the most common subtype of non-Hodgkin lymphoma, presents an aggressive clinical profile. Although a significant number of patients can be cured with standard front-line therapy, many will exhibit refractory disease or relapse following an initial response and are ineligible to transplant. These patients face a very poor prognosis and need novel treatment option to improve their outcomes ¹ .

According to NCCN Guidelines, Minjuvi ^® is listed as one of the preferred 2 ^nd line treatments for DLBCL patients who are ineligible for transplantation ² . The marketing authorization was based on the data from L-MIND study, an open label, multicenter, single arm Phase 2 trial. The primary endpoint results showed an objective response rate (ORR) of 60%, which includes a complete response rate (CR) of 43% and a disease control rate (DCR) of 75% ³ .

"The launch of Minjuvi ^® brings a new treatment option to relapsed or refractory non-transplant eligible DLBCL adult patients due to its innovative characteristics and proven efficacy, with a reasonable safety profile," said Dr Guilherme Perini, hematologist specialized in Lymphomas at Hospital Israelita Albert Einstein. "Minjuvi ^® will improve patients' standard of care and it is a highly anticipated therapy for our patients," added Dr Perini.

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. In July 2023, ANVISA (Agência Nacional de Vigilância Sanitária) granted Market Authorization for Minjuvi ^® under the rare disease designation according to Resolution RDC 205/2017. Additionally, in October 2023, Knight received pricing approval for Minjuvi ^® from the Drugs Market Regulation Chamber ("CMED").

"In line with Knight's commitment to advancing healthcare in Latin America, we are excited to launch Minjuvi in Brazil, an innovative treatment option for addressing a current unmet medical need," said Samira Sakhia, Knight Therapeutics President and CEO.

"Knight's team in Brazil is thrilled to make Minjuvi ^® available to health care professionals and centers, improving DLBCL patient care in the country," said Cristiane Coelho, Knight Therapeutics Brazil General Manager.

About 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. In 2024, Incyte was assigned such license and now exclusively holds such rights. 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 has received accelerated approval based on the overall response rate. Continued approval for this indication may be contingent upon verification and description of the clinical benefit in confirmatory trial(s).

In Europe, Minjuvi ^® (tafasitamab) received conditional marketing authorization, 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 indications have not been established in pivotal trials.
