Takeda Pharmaceutical Company Limited announced that the FDA has approved LIVTENCITY™ (maribavir) for the treatment of adults and pediatric patients (12 years of age or older and weighing at least 35 kg) with post-transplant cytomegalovirus (CMV) infection/disease that is refractory to treatment (with or without genotypic resistance) with ganciclovir, valganciclovir, cidofovir, or foscarnet.1 Overall, more than twice the proportion of adult transplant patients with refractory or resistant (R/R) CMV infection/disease achieved confirmed CMV DNA level <LLOQ* (lower limit of quantification, i.e. <137 IU/mL) at Week 8 (end of treatment phase), the study’s primary endpoint, with LIVTENCITY (56%; n=131/235), compared to those treated with conventional antiviral therapies (24%; n=28/117) (adjusted difference: 33%, 95% CI: 23–43; p<0.001). LIVTENCITY is Takeda’s second new molecular entity to receive FDA approval in FY2021.
“Today’s announcement redefines the management of post-transplant CMV with the approval of the first and only treatment for transplant patients with CMV that is refractory with or without resistance, a significantly underserved and vulnerable patient community,” said Ramona Sequeira, President, U.S. Business Unit and Global Portfolio Commercialization, Takeda Pharmaceutical Company Limited. “People undergoing transplants have a lengthy and complex healthcare journey; with the approval of this treatment, we’re proud to offer these individuals a new oral antiviral to fight CMV infection and disease. We are grateful for the contributions of the patients and clinicians who participated in our clinical trials, as well as the dedication of our scientists and researchers.”
LIVTENCITY is a new molecular entity which targets CMV at pUL97, resulting in inhibition of viral DNA replication, encapsidation and nuclear egress. Though a rare disease overall, CMV is one of the most common infections experienced by transplant recipients, with an estimated incidence rate of around 16%–56% in solid organ transplant (SOT) recipients and 30%–70% in hematopoietic stem cell (HSCT) transplant patients. CMV can be acquired or reactivated following transplant leading to serious consequences—including loss of the transplanted organ and failure of the graft—or loss of life. In patients with compromised immunity, CMV causes clinically challenging complications that can be fatal.
