Novartis has received green lights from both the European Commission and the UK's Medicines and Healthcare products Regulatory Agency (MHRA) for multiple sclerosis (MS) therapy Kesimpta (ofatumumab).
The drug is a fully human anti-CD20 monoclonal antibody (mAb) thought to work by binding to a distinct epitope on the CD20 molecule, inducing potent B-cell lysis and depletion. It enables faster repletion of B cells versus other anti-CD20 monoclonal antibodies and so may offer flexibility in the management of RMS, according to the drugmaker.
As per its licence, Kesimpta can be used to treat adults with relapsing forms of multiple sclerosis (RMS) with active disease, defined by clinical or imaging features.
Novartis says it has the potential to become a recognised treatment option for eligible UK patients that can be self-administered, with initial guidance from an appropriately trained healthcare professional, once monthly at home via the Sensoready autoinjector pen.
Initial decisions on NHS use of Kesimpta from the National Institute for Health and Care Excellence (NICE) and the Scottish Medicine Consortium (SMC) are expected later this year.
The drug's approval rides on the back of two Phase III ASCLEPIOS studies, which met primary endpoints demonstrating a significant reduction in the number of relapses versus teriflunomide, evaluated as the annualised relapse rate (ARR).
Across both studies, 946 patients were assigned to receive Kesimpta and 936 teriflunomide; Kesimpta showed a significant reduction in ARR by 50.5% and 58.5% compared with teriflunomide in ASCLEPIOS I and II, respectively.
“The MS Trust is delighted that ofatumumab, the first self-administered B-cell therapy for people with relapsing forms of MS with active disease, has been granted both MHRA and EMA licences. Relapsing forms of MS can have a serious and difficult impact on all aspects of people’s lives,” said David Martin, chief executive, Multiple Sclerosis Trust. “Ofatumumab can potentially give independence to a group of people who have previously had to rely upon regular medical visits to treat this life-changing condition. We hope ofatumumab will provide people living with relapsing forms of MS a sense of independence, and positively impact their lives by reducing their disease progression.”
“The MS clinical community welcomes [Kesimpta's approval], which provides us with a new treatment option to support a group of patients who, to date, have continued to experience disease activity with this devastating condition,” added consultant neurologist Dr Owen Pearson at Morriston Hospital, Swansea. “MS is a complex disease, and each individual will respond differently to disease-modifying therapies. The self-administration of ofatumumab benefits both the clinical community and eligible patient community.”
NHS England is rolling out an injection that dramatically cuts the amount of time breast cancer patients spend in hospital from two and a half hours to as little as five minutes across the country, following a deal with its manufacturer Roche.
Phesgo is a new fixed-dose combination of pertuzumab with trastuzumab that previously would have been given as separate IV infusions. More than 3,600 new patients each year will benefit from the treatment, as well as others who will switch from their current therapy to the single injection.
The injection will be offered to eligible people with HER2-positive breast cancer, which accounts for 15% of all breast cancers, and can be given alongside chemotherapy or on its own.
NHS England notes that the five-minute jab also “significantly cuts the COVID infection risk for cancer patients by reducing the amount of time spent in hospital and frees up time for clinicians in chemotherapy units”.
The agreement between the health service, NICE and Roche means Phesgo comes at no extra cost to the NHS.
“Approval of Phesgo being used on the NHS in England is fantastic news as thousands of women with HER2 positive breast cancer will now benefit from a quicker and kinder treatment method,” said Baroness Delyth Morgan, chief executive at Breast Cancer Now. “Reducing the time patients need to spend in hospital, this more efficient treatment method also promises to free up precious time for healthcare professionals when the NHS is already under unprecedented strain due to COVID-19.
Exscientia has announced that the world's first artificial intelligence (AI)-designed molecule for immuno-oncology has entered human clinical trials.
The A2a receptor antagonist, which is in development for adult patients with advanced solid tumours, was co-invented and developed through a joint venture between Exscientia and Evotec.
Tumour cells produce high levels of adenosine, a molecule that helps them escape immune system detection by binding to the A2a receptor on cancer fighting T-cells, reducing T-cell ability to eliminate disease. The AI-designed A2a receptor antagonist is being investigated for its ability to prevent adenosine from binding to the T-cell receptor and potentially promote anti-tumour T-cell activity.
According to the company, the drug candidate has potential for best-in-class characteristics, “with high selectivity for the target receptor, bringing together potential benefits of reduced systemic side effects as well as minimal brain exposure to avoid undesired psychological side effects”.
“Our selective A2a receptor antagonist addresses a next-generation immuno-oncology strategy to empower the human immune system by reversing the effects of high adenosine concentrations,” noted Andrew Hopkins, Exscientia's chief executive. “We set ambitious therapeutic objectives for this project, especially high selectivity for the A2a receptor and central nervous system (CNS) sparing properties, in order to reduce the likelihood of systemic side effects. Even with these challenging objectives, we were able to discover our candidate molecule within eight months of project initiation.”
