NICE recommends LIVTENCITY®▼ (maribavir) for the treatment of adults with post-transplant cytomegalovirus (CMV) refractory (with or without resistance) to prior therapies

  • Takeda UK Ltd. is pleased to announce that NICE has recommended the use of LIVTENCITY®▼ (maribavir) as a twice daily oral treatment for adult patients with post-transplant cytomegalovirus (CMV) infection and/or disease that is refractory (with or without resistance) to one or more prior therapies, within their final appraisal determination (FAD) published today.[i],[ii]

  • CMV is a frequent complication after transplantation and can lead to serious morbidity, including rejection of Transplanted Organ and Failure of Graft, and in some cases mortality. [iii], [iv]

  • LIVTENCITY is the first and only oral treatment that inhibits CMV-specific UL97 protein kinase and its natural substrates.[v]

LONDON, Dec. 8, 2022 /PRNewswire/ -- Takeda UK Ltd. today announced that the National Institute for Health and Care Excellence (NICE), the health technology appraisal body in England and Wales, has issued its Final Appraisal Determination (FAD) recommending LIVTENCITY®▼ (maribavir) in line with its license, for the treatment of cytomegalovirus (CMV) infection and/or disease that is refractory (with or without resistance) to one or more prior therapies, including ganciclovir, valganciclovir, cidofovir or foscarnet in adult patients who have undergone a hematopoietic stem cell transplant (HSCT) or solid organ transplant (SOT).ii This recommendation follows recent Marketing Authorisation granted by the Medicines and Healthcare products Regulatory Agency (MHRA) on 11th November 2022. LIVTENCITY will be made available on the NHS to eligible patients within 90 days, in line with NICE guidance.

Cytomegalovirus (CMV) infection can be a significant complication after transplantation[iii],[vi] and can lead to increased organ rejection and higher hospitalisation rates.[iv],[vii]  Existing therapies to treat post-transplant CMV infections may demonstrate serious side effects or may fail to adequately suppress viral replication.[viii] Until today there have been no treatments recommended by NICE for treating CMV infection that is refractory or resistant to other treatments. CMV infections that are refractory or resistant to currently available antivirals are a major cause of morbidity and mortality among solid organ transplant (SOT) and allogeneic haematopoietic stem cell transplant (HSCT) recipients.[ix]  Additionally, existing therapies may require or prolong hospitalisation due to administration and may be poorly tolerated.[x],[viii]   

Rachel Miller, Lead Nurse of Anthony Nolan, a UK charity that provides donor grafts for hematopoietic stem cell transplantation and supports transplant and cell therapy patients through multidisciplinary research and patient advocacy, said, "CMV reactivation can have a significant impact for some post-transplant patients with weak immune systems. Often infections can persist over a prolonged period, resulting in patients having to stay in hospital for longer or managing repeated hospital visits. Patients who experience CMV reactivation tend to have a reduced quality of life, impacting recovery both physically and psychologically. This is why it's so important that new and effective therapeutic options are developed and made available to improve patients' outcomes."

In the United Kingdom, there are approximately over 4,700 solid organ transplant (SOT) procedures and over 1,700 allogeneic haematopoietic stem cell transplant (HSCT) procedures every year[xi], [xii]. CMV infection occurs in approximately 18% of SOT patients overall[xiii] and approximately 50% of allogeneic HSCT patients[xiii].  Current antiviral treatment options for post-transplant CMV infections have unfavourable toxicities, such as neutropenia or nephrotoxicity, that may impact patient care and transplant outcomes.[xiv] In the SOLSTICE trial fewer patients were seen to have these toxicities.[xv]

"Transplant patients with a weak immune system are particularly vulnerable to the risk of CMV infection. The infection itself can affect multiple organs, including the lungs, liver, kidney, stomach and eyes, causing severe damage and even loss of the transplanted organ", said, Dr Mark Harber, Consultant Nephrologist at the Royal Free London NHS Foundation Trust, UK. "Standard anti-CMV treatments are hampered by dose related toxicities and require a complex balancing act of dose adjustments to minimise adverse events such as nephrotoxicity. I welcome the approval of maribavir for patients with difficult to treat CMV infection. This new oral anti-CMV treatment which appears to have few significant side effects is a welcome addition to the options for treating this infection and has the potential to improve the outcome of many of these patients."

The NICE recommendation was based on the Phase 3 SOLSTICE trial, which evaluated the safety and efficacy of maribavir versus conventional antiviral therapies - ganciclovir, valganciclovir, cidofovir or foscarnet - for the treatment of adult HSCT and SOT recipients with resistant/ refractory CMV infection.[xv]

Commenting on the recommendation, Simon Meadowcroft, Country Medical Director, Takeda UK & Ireland, said, "We are delighted that NICE has chosen to make LIVTENCITY available via NHS England for patients who have received ether a haematopoietic stem cell transplant or an organ transplant, and are suffering from infection with the CMV virus which has not been successfully treated with currently available antiviral medicines. Infection with CMV, one of the most common and serious post-transplant infections, can have serious consequences for patients including potential failure of the transplanted organ. The availability of a new treatment option will make a real difference to this vulnerable group of patients."

Peter Wheatley-Price, Market Access & Pricing Director, Takeda UK & Ireland, said, "This is a great example of how Takeda UK and NICE have worked in partnership to get access for this therapy. We are pleased to build on our great working relationship with NICE to achieve this positive outcome."

Notes to Editors

About LIVTENCITY (maribavir)

Maribavir, an orally bioavailable anti-CMV compound, is the first and only antiviral agent that targets and inhibits the pUL97 protein kinase and its natural substrates.[v], [ii]

On 11th November 2022, the MHRA granted Marketing Authorization for LIVTENCITY (maribavir) for the treatment of CMV infection and/or disease that is refractory (with or without resistance) to one or more prior therapies, including ganciclovir, valganciclovir, cidofovir or foscarnet in adult patients who have undergone a HSCT or SOT.  LIVTENCITY is approved in this indication in the UK, the EU and EEA (European Economic Area), In November 2021, maribavir received U.S. Food and Drug Administration (FDA) approval, under the brand name LIVTENCITY for the treatment of adults and paediatric 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. U.S., Canada, and Australia.ii Regulatory filings are underway with other health authorities worldwide.
