Approval decision expected in 4Q 2022
LAUSANNE, Switzerland, September 16, 2022--(BUSINESS WIRE)--ADC Therapeutics SA (NYSE: ADCT) and Swedish Orphan Biovitrum AB (Sobi®) today announced the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency has adopted a positive opinion recommending the marketing authorization of ZYNLONTA® (loncastuximab tesirine) for the treatment of relapsed or refractory diffuse large B-cell lymphoma (DLBCL). The positive opinion from the CHMP is now referred to the European Commission for an approval decision.
Earlier this year, ADC Therapeutics announced an exclusive license agreement with Sobi to develop and commercialize ZYNLONTA for all hematologic and solid tumor indications in Europe and select international territories.
"The positive CHMP opinion demonstrates significant progress toward bringing ZYNLONTA to DLBCL patients in Europe," said Ameet Mallik, Chief Executive Officer of ADC Therapeutics. "We are committed, along with our partners, to making ZYNLONTA available to as many patients as possible worldwide and look forward to the European Commission’s final decision, which is anticipated in the fourth quarter of 2022."
"Today’s announcement marks an important step toward meeting the critical needs of patients with relapsed and refractory large B-cell lymphoma across the EU," said Anders Ullman, Head of Research & Development and Chief Medical Officer at Sobi. "We believe Sobi's heritage and strong presence in hematology will provide a competitive platform for bringing loncastuximab tesirine to more patients."
The opinion is based on data from LOTIS-2, a large (n=145) Phase 2 multinational, single-arm clinical trial of ZYNLONTA for the treatment of adult patients with relapsed or refractory DLBCL following two or more prior lines of systemic therapy. In April 2021, the U.S. Food and Drug Administration (FDA) granted accelerated approval of ZYNLONTA as the first CD19-targeted antibody drug conjugate (ADC) as a single-agent treatment for adult patients with relapsed or refractory DLBCL after two or more lines of systemic therapy. In September 2021, the European Commission granted Orphan Drug Designation to ZYNLONTA for the treatment of DLBCL.
"The results of the LOTIS-2 study demonstrated significant clinical benefit for patients with recurrent diffuse large B-cell lymphoma, an aggressive subtype of non-Hodgkin lymphoma," said John Radford, Professor of Medical Oncology at The University of Manchester and The Christie NHS Foundation Trust in Manchester, UK. "I am encouraged by the potential of ZYNLONTA to help patients in this underserved treatment population. If approved by the European Commission, ZYNLONTA will offer a new therapeutic option to patients with this difficult to treat lymphoma and gives hope to them and their families."
ADC Therapeutics has an exclusive license agreement with Mitsubishi Tanabe Pharma Corporation (MTPC) for the development and commercialization of ZYNLONTA for all hematologic and solid tumor indications in Japan. In addition, Overland ADCT BioPharma, a joint venture formed by Overland Pharmaceuticals and ADC Therapeutics, is working to develop and commercialize ZYNLONTA in greater China and Singapore. Overland ADCT BioPharma is now conducting a registrational pivotal Phase 2 clinical trial of ZYNLONTA in relapsed or refractory DLBCL in China.
About ZYNLONTA® (loncastuximab tesirine-lpyl)
ZYNLONTA® is a CD19-directed antibody drug conjugate (ADC). Once bound to a CD19-expressing cell, ZYNLONTA is internalized by the cell, where enzymes release a pyrrolobenzodiazepine (PBD) payload. The potent payload binds to DNA minor groove with little distortion, remaining less visible to DNA repair mechanisms. This ultimately results in cell cycle arrest and tumor cell death.
The U.S. Food and Drug Administration (FDA) has approved ZYNLONTA (loncastuximab tesirine-lpyl) for the treatment of adult patients with relapsed or refractory (r/r) large B-cell lymphoma after two or more lines of systemic therapy, including DLBCL not otherwise specified, DLBCL arising from low-grade lymphoma and also high-grade B-cell lymphoma. The trial included a broad spectrum of heavily pre-treated patients (median three prior lines of therapy) with difficult-to-treat disease, including patients who did not respond to first-line therapy, patients refractory to all prior lines of therapy, patients with double/triple hit genetics and patients who had stem cell transplant and CAR-T therapy prior to their treatment with ZYNLONTA. This indication is approved by the FDA under accelerated approval based on overall response rate and continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.
ZYNLONTA is also being evaluated as a therapeutic option in combination studies in other B-cell malignancies and earlier lines of therapy.
