PRESS RELEASE - For UK consumer, medical and trade media only

  • Diffuse large B-cell lymphoma (DLBCL) is an aggressive sub-type of non-Hodgkin’s lymphoma, with nearly 5,500 new diagnoses in the UK each year1
  • Bispecific antibodies represent a new class of therapies that work by introducing a local immune cell to a cancer cell, enabling the immune cell to attack and destroy the cancer2
     
  • As the first and only subcutaneous bispecific injection, epcoritamab could offer eligible patients an additional treatment option3

MAIDENHEAD, UK, [23 October 2023] – AbbVie (NYSE: ABBV) today announced that the UK Medicines and Healthcare products Regulatory Agency has granted conditional Marketing Authorisation for Tepkinly®▼ (epcoritamab) as a monotherapy for the treatment of adults with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL), after two or more systemic therapies4. The conditional Marketing Authorisation for Great Britain is based on the single-arm Phase 1/2 EPCORE NHL-1 trial data, which demonstrated a 62% (86/139) overall response rate and 39% (54/139) complete response rate in patients. However, further data are awaited from an ongoing phase 3 confirmatory study4,5,6.

Epcoritamab is the first and only licensed subcutaneous bispecific treatment option for adult patients with R/R DLBCL after two or more lines of systemic therapy, in Great Britain4. In contrast to some existing therapeutic options, epcoritamab does not require cell collection and engineering4,5,7. The treatment is administered to eligible patients by clinicians as a weekly subcutaneous injection for 12 weeks, then moves to 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 effects4. Eligible patients are able to start epcoritamab therapy after appropriate pre-medication has been administered and monitoring for adverse events is available4,5. Patients stay in hospital for 24 hours after the first full dose to monitor for side effects4,5.

DLBCL is the most common sub-type of non-Hodgkin’s lymphoma (NHL), an aggressive blood cancer that develops in the lymphatic system, causing B-cell lymphocytes, a type of white blood cell, to grow abnormally1. There are nearly 5,500 new DLBCL diagnoses each year in the UK1. For the approximately 700 people in the UK with R/R DLBCL who have already received two or more treatments and require further therapy, prognosis is poor8. There are few treatments available for this patient population, and these are typically administered intravenously, via a needle or tube inserted into a vein9.

“Despite recent therapeutic advances, treatment options for patients with R/R DLBCL after two previous therapies are limited. For such patients living with this type of aggressive blood cancer, many experience disease progression and have poor prognosis”, said Professor Chris Fox, Professor of Haematology, School of Medicine, University of Nottingham and Honorary Consultant Haematologist, Nottingham University Hospitals NHS Trust. “As a novel bispecific antibody, given as a subcutaneous injection, epcoritamab offers a new treatment option for this difficult-to-treat patient group.”

Bispecific antibodies represent a new class of therapies that use the body’s immune system to kill cancer cells2. Epcoritamab is a bispecific antibody designed to simultaneously bind to two proteins, cluster of differentiation (CD)3 on T cells in the immune system and CD20 on cancerous B cells (a type of white blood cell), in order to induce T-cell mediated killing of cancerous B cells2. By targeting two cells, epcoritamab brings the immune T cell together with the cancerous B cell and activates the T cell to destroy the B cell2. Epcoritamab must be delivered under the supervision of a healthcare professional qualified in the use of anti-cancer therapies with access to appropriate medical support to manage potential serious side effects, such as cytokine release syndrome (CRS) events4,5.

Common serious adverse reactions observed in the single-arm Phase 1/2 EPCORE NHL-1 trial included CRS events, pneumonia, upper respiratory tract infections, febrile neutropenia, immune effector cell-associated neurotoxicity syndrome (ICANS) and pyrexia4,5.

The conditional Marketing Authorisation is based on data from the single-arm Phase 1/2 EPCORE NHL-1 trial investigating epcoritamab as monotherapy for 139 patients with R/R DLBCL after two or more lines of systemic therapy4,5. In the Phase 1/2 NHL-1 clinical trial, the overall response rate was 62% (n=86/139), meaning 62% of participants’ blood cancer went down by half or they had no cancerous cells remaining in their body (partial response or complete response)10. The complete response rate was 39% (n=54/139), meaning there is no evidence of disease from tests and scans in 39% of these hard-to-treat patients, who on average had already been through three types of treatment before starting the trial10,11. The NHL-1 trial results demonstrate that 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 therapy4,5,10.

“AbbVie is committed to advancing care for people living with blood cancer. Today’s news is an important step forward in enabling us to provide this hard-to-treat patient group with an innovative subcutaneous treatment option”, said Belinda Byrne, Medical Director, AbbVie UK. “We are working with the NHS and relevant authorities to bring access to eligible patients and clinicians throughout the UK as quickly as possible.”

NOTES TO EDITORS:

Glossary

B cells / B lymphocytes: A type of white blood cell (an immune cell) that fights infection by producing antibodies12. This is the blood cell that becomes cancerous in DLBCL1.
Complete response rate of 39% (n=54/139)10: The total number of people in the trial who experienced the disappearance of all evidence of lymphoma in the body from tests and scans after treatment14.
Conditional Marketing Authorisation: The conditional Marketing Authorisation is based on data from the single-arm Phase 1/2 EPCORE NHL-1 trial investigating epcoritamab as monotherapy for 139 patients with R/R DLBCL after two or more lines of systemic therapy3,9. The Medicines and Healthcare products Regulatory Agency may grant a conditional Marketing Authorisation where a medicinal product fulfils an unmet medical need and where comprehensive clinical data is not yet complete, but it is judged that such data will become available soon.
Median duration of response of 15.6 months4: The average length of time that a tumour continues to respond to treatment without the cancer growing or spreading13.
Median overall survival of 19.4 months10: The average time patients live for from the time they start treatment with epcoritamab13.
Overall response rate of 62% (n=86/139)10: The total number of people in the trial whose cancer has either gone away (a complete response) or shrunk (a partial response)14.
Refractory: Lymphoma that does not respond well to the first choice of treatment, and patient does not go into remission1.
Relapse: Lymphoma that comes back after successful treatment and a period of remission1.
Remission: When there is no evidence of lymphoma in the body from tests and scans after treatment, and no symptoms1.
T cells / T lymphocytes: A type of white blood cell (immune cells) that help to protect us from viruses and cancers by attacking them directly12.

About DLBCL
Lymphoma is a blood cancer that causes tumours to form in the lymphatic system1. Lymphoma is divided into two main types called Hodgkin’s lymphoma and NHL15. DLBCL is a type of NHL and makes up almost 30% of all cases of NHL globally16. There are approximately 5,500 new cases of DLBCL in the UK each year1. Patients with DLBCL typically have swollen lymph nodes in the neck, armpit or groin1.

About TEPKINLY® (epcoritamab)
Epcoritamab has been granted conditional Marketing Authorisation as a subcutaneous injection to treat adults in Great Britain with DLBCL that has come back (relapsed) or that did not respond to previous treatment (refractory), and who have received two or more treatments for their cancer4. The treatment is administered to eligible patients by clinicians as a weekly subcutaneous injection for 12 weeks, then moves to 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 effects4. 

Epcoritamab is an immunoglobulin G1-bispecific antibody created using Genmab’s proprietary DuoBody® technology2. Genmab’s DuoBody®-CD3 technology is designed to direct cytotoxic T cells selectively to elicit an immune response towards target cell types2. Epcoritamab is designed to simultaneously bind to CD3 on T cells and CD20 on B cells and induces T-cell mediated killing of CD20+ cells2. CD20 is expressed on B cells and is a clinically validated therapeutic target in many B-cell malignancies, including DLBCL17,18. Epcoritamab was designed specifically for high-specificity binding2.

About the EPCORE™ NHL-1 clinical trial3,4,19
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 NHLs 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%), 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. More information can be found at https://classic.clinicaltrials.gov/ct2/show/NCT03625037.
