Scottish Medicines Consortium (SMC) Approves First Subcutaneous Bispecific Treatment Option Tepkinly®▼(epcoritamab) for Adults with an Aggressive Form of Blood Cancer After Two or More Lines of Systemic Therapy

  • For the first time, adults in Scotland with diffuse large B-cell lymphoma (DLBCL) whose cancer has returned or not responded to at least two prior treatments, will have access to a subcutaneous bispecific treatment option administered as an injection under the skin[1],[2].
  • Epcoritamab is part of a new class of therapies called bispecific antibodies. Bispecific antibodies help the body’s immune system to attack and destroy cancerous cells[3].
  • DLBCL is an aggressive blood cancer, with approximately 430 adults diagnosed with the disease in Scotland each year. For patients whose cancer has returned or has not responded to at least two prior treatments, prognosis is poor[4],[5],[6].

MAIDENHEAD, UK, [10th June 2024] – AbbVie (NYSE: ABBV) today announced that the Scottish Medicines Consortium (SMC) has recommended Tepkinly® (epcoritamab) as a treatment option for adults with DLBCL whose cancer has returned or not responded to at least two prior treatments1. Following the recommendation by the National Institute for Health and Care Excellence (NICE) in March 2024, this means that epcoritamab is available for use within the NHS across the UK.

The SMC recommendation is based on the single-arm Phase 1/2 EPCORE NHL-1 trial data, in which subcutaneous epcoritamab monotherapy demonstrated responses in challenging-to-treat, relapsed or refractory (R/R) DLBCL patients who had received at least two prior treatments[7]. An overall response rate of 62% (n=86/139) was seen in this study, meaning 62% of participants’ blood cancer either went down by half (partial response) or showed no evidence of disease from tests and scans (complete response), and 39% (n=54/139) of patients achieved a complete response, where there is no evidence of disease from tests and scans2,7,[8],[9].

Epcoritamab is the first and only subcutaneous T-cell engaging bispecific antibody licensed for the treatment of adult patients with R/R DLBCL after two or more lines of systemic therapy1.

‘We are delighted that the SMC has made epcoritamab available to eligible people in Scotland living with this aggressive blood cancer. Epcoritamab is a bispecific antibody, administered as an injection under the skin, designed to recognise and attach to the cancer cells and immune cells, so that the body’s immune system can destroy them,’ said Blood Cancer UK’s Scotland Policy Officer, Josh Hill. ‘While most people go into remission after standard treatment, some people can see their cancer returning after each treatment option they try, leaving them feeling unsettled about what the future holds and what the next treatment option will entail.’

DLBCL is an aggressive blood cancer, with approximately 430 adults in Scotland, and nearly 5,500 adults across the UK being diagnosed each year 5,6,[10]. For patients who have R/R DLBCL, meaning their cancer has returned or has not responded to at least two prior treatments, prognosis is poor4. There are few treatments available for this patient population, and these are typically administered intravenously, via a needle or tube inserted into a vein, in a hospital setting[11].

Epcoritamab is part of a new class of therapies called bispecific antibodies. Bispecific antibodies help the body’s immune system to attack and destroy cancerous cells. Epcoritamab is designed to simultaneously attach to two different cells, one immune T cell and one cancerous lymphoma cell, bringing them together so that the immune T cell is activated to destroy the cancerous lymphoma cell2,3. While epcoritamab is given in a hospital setting, it is administered subcutaneously, meaning it is an injection under the skin2.

‘Adults with DLBCL who have already been through two treatment options, but whose cancer has returned or has not responded, face limited alternative treatment options. It is important for physicians to have multiple treatment options, including products with different mechanisms of action and modes of administration, to provide patients with the choice of a treatment that is right for them. That’s why today’s approval is welcomed news for clinicians and eligible DLBCL patients.’ said Dr Angus Broom, Consultant Haematologist at the Western General Hospital in Edinburgh.

‘Epcoritamab is the first bispecific treatment option in this disease area that can be administered as an injection under the skin, in a hospital setting. This could allow patients to potentially be treated close to home, as this treatment can be delivered in a wider hospital setting rather than just specialist centres.’

In contrast to some existing therapeutic options, epcoritamab does not require cell collection and engineering2. The treatment is given to eligible patients by a blood cancer specialist doctor or nurse as an injection under the skin, weekly for 12 weeks, then every other week for 24 weeks (12 injections), before continuing as one injection every 4 weeks until treatment is discontinued, either due to cancer progression or side effects2. Eligible patients can start epcoritamab therapy after appropriate pre-medication has been administered and monitoring for adverse events is available2. Patients stay in hospital for 24 hours after the first full dose to monitor for side effects2.

In the Phase 1/2 NHL-1 clinical trial, epcoritamab prevented growth or spread of the cancer for an average of 15.6 months, and the patients lived for an average of 19.4 months from the start of epcoritamab therapy2,7. The most common adverse reactions of any grade (≥20%) observed in the trial were cytokine release syndrome (CRS), fatigue, neutropenia, injection-site reactions, abdominal pain, pyrexia, nausea and diarrhoea2.

‘Knowing that relapsed or refractory patients with DLBCL have limited treatment options, and the impact this may have on both their prognosis, mental wellbeing, and quality of life, drives us at AbbVie to advance standards of care. Today’s SMC decision is a result of our commitment to bring innovation to relapsed/refractory DLBCL patients and their loved ones.,’ said Rachael Millward, Medical Director, AbbVie UK.

About DLBCL

Lymphoma is a blood cancer that causes tumours to form in the lymphatic system10. Lymphoma is divided into two main types: Hodgkin’s lymphoma and non-Hodgkin’s lymphoma (NHL)[13]. DLBCL is a type of NHL, and makes up almost 30% of all cases of NHL globally[14]. There are approximately 5,500 new cases of DLBCL in the UK each year, with approximately 430 adults being diagnosed with the disease in Scotland5,6,10. For around 700 of these patients in the UK whose cancer has returned or has not responded to at least two prior treatments, prognosis is poor4,5,[15]. Patients with DLBCL typically have swollen lymph nodes in the neck, armpit or groin10.

About Tepkinly (epcoritamab)

Epcoritamab is recommended by the SMC as a subcutaneous injection to treat adults in Scotland with DLBCL that has come back (relapsed) or that did not respond to prior treatment (refractory), and who have received two or more treatments for their cancer1. The treatment is given to eligible patients by a blood cancer specialist doctor or nurse as an injection under the skin, weekly for 12 weeks, then every other week for 24 weeks (12 injections), before continuing as one injection every 4 weeks until treatment is discontinued, either due to cancer progression or side effects2.

 

Epcoritamab is an immunoglobulin G1 bispecific antibody created using Genmab’s proprietary DuoBody® technology3. Genmab’s DuoBody®-CD3 technology is designed to direct cytotoxic T cells selectively to elicit an immune response towards target cell types3. Epcoritamab is designed to simultaneously bind to cluster of differentiation (CD) 3 on T cells and CD20 on B cells, and induces T-cell-mediated killing of CD20+ cells3. CD20 is expressed on B cells, and is a clinically validated therapeutic target in many B-cell malignancies, including DLBCL[16],[17]. Epcoritamab was designed specifically for high-specificity binding3.

Epcoritamab is being co-developed by AbbVie and Genmab as part of the companies’ oncology collaboration. The companies will share commercial responsibilities in the U.S. and Japan, with AbbVie responsible for further global commercialisation.

About the EPCORE NHL-1 clinical trial[18],[19]

EPCORE™ NHL-1 is a single-arm, open-label, multicentre, safety and preliminary efficacy trial of epcoritamab that includes a Phase 1 first-in-human dose escalation part; a Phase 2a expansion part; and a dose optimisation part. The trial was designed to evaluate subcutaneous epcoritamab in patients with relapsed, progressive or refractory CD20+ mature B-cell NHL, including DLBCL. Data from the dose escalation part of the study, which determined the recommended Phase 2 dose, were published in September 2021. In the Phase 2 expansion part, additional patients were treated with epcoritamab to further explore the safety and efficacy of epcoritamab, in three cohorts of patients with different types of R/R B-cell NHL who had limited therapeutic options.

The primary endpoint of the Phase 2 expansion part was overall response rate as assessed by an independent review committee. Secondary efficacy endpoints included duration of response, complete response rate, progression-free survival, overall survival, time to response, time to next therapy and rate of minimal residual disease negativity. The most common adverse reactions of any grade (≥20%) observed in the trial were CRS (50.9%), fatigue (30.5%), neutropenia (30.5%), injection-site reactions (29.9%), pyrexia (23.4%), abdominal pain (23.4%), nausea (21.6%) and diarrhoea (21.0%). The most common Grade 3–4 adverse reactions (≥2%) were neutropenia (23.4%), anaemia (10.2%), thrombocytopenia (7.2%), pneumonia (6.0%), fatigue (3.0%), CRS (3.0%), febrile neutropenia (2.4%), oedema (2.4%) and hypophosphataemia (2.4%). The most common serious adverse reactions (≥2%) were CRS (31.1%), pneumonia (7.2%), upper respiratory tract infections (2.4%), febrile neutropenia (2.4%), immune effector cell-associated neurotoxicity syndrome (ICANS; 2.4%) and pyrexia (2.4%). Four patients (2.4%) experienced a fatal adverse reaction (ICANS in one patient [0.6%] and pneumonia in three patients [1.8%]).

Results from the Phase 2 expansion part of the study were published in December 2022.18 More information can be found at https://classic.clinicaltrials.gov/ct2/show/NCT03625037.
