PRESS RELEASE
Immunocore announces the presentation of initial data from the Phase 1 ImmTAV® trial for chronic Hepatitis B at the EASL International Liver Congress™
IMC-I109V, T cell receptor bispecific, targets an envelope antigen
Single Ascending Dose portion of Phase 1 study to evaluate safety, antiviral activity, and pharmacokinetics
In the initial cohort, HBsAg declines and ALT elevations indicated that a single, very low dose of IMC-I109V elicited on-target activity, consistent with mechanism of action and without any adverse
events
(OXFORDSHIRE, England & CONSHOHOCKEN, Penn. & ROCKVILLE, Md., US, 25 June 2022) Immunocore Holdings plc (Nasdaq: IMCR) (“Immunocore” or the “Company”), a commercial-stage biotechnology company pioneering the
development of a novel class of T cell receptor (TCR) bispecific immunotherapies designed to treat a broad range of diseases, including cancer, autoimmune and infectious diseases, today announced that initial data from the first three patients in
the first-in-human clinical trial of IMC-I109V was presented at the EASL International Liver Congress in London, UK.
IMC-I109V is a TCR bispecific designed to specifically eliminate HBV-infected hepatocytes expressing hepatitis B surface antigen (HBsAg) via T cell redirection. IMC-I109V is designed to overcome T cell dysfunction by
recruiting non-exhausted T cells to eliminate hepatocytes harbouring covalently closed circular DNA or integrated HBV DNA. Elimination of these cells is necessary to achieve a state of ‘functional cure’ defined as sustained HBsAg loss in addition
to undetectable HBV DNA 6 months post-treatment. Since the mechanism results in hepatocyte lysis, transient liver enzyme increases are expected, necessitating a conservative dosing schedule in the Company’s first-in-human study of IMC-I109V.
In this first cohort, three patients each received a single dose of 0.8 mcg, based on the minimum anticipated biological effect level (MABEL). The dose in this initial cohort was well tolerated and was not associated
with adverse events were reported in any patient. The maximum serum concentrations of IMC-I109V were consistent with the dose level. By hour 12, serum concentrations declined below the lower limit of quantification. IL-6 cytokine levels increased
within the first 24 hours in all three patients, which is consistent with the IMC-I109V mechanism of action. Small and transient increases in alanine transaminase (ALT), albeit within the normal range, were observed in the first few days after
dosing, before returning to normal levels. In two of the three patients, serum HBsAg levels transiently decreased, with the same kinetics as ALT, by 11-15% during Days 3-15 post infusion, before returning to baseline within 3 weeks post-infusion.
“We designed our T cell receptor based bispecific proteins to harness the immune system to potentially achieve a functional cure for HBV,” said David Berman, Head of Research &
Development at Immunocore. “Although only a few patients received a single, very low dose of IMC-I109V, we are very encouraged by our observations of transient decrease in HBV surface antigen, as well as transient elevations in ALT and
cytokines, which match the profile we had hypothesized based on the IMC-I109V mechanism of action. We look forward to enrolling more patients at higher doses in the Phase 1 program.”

The trial is an open label study evaluating the safety, antiviral activity, and pharmacokinetics of IMC-I109V in HLA-A*02:01 positive patients with chronic hepatitis B who are non-cirrhotic, HBeAg-negative and
virally suppressed on nucleos(t)ide analogues. Part 1 is a single ascending dose to identify a safe and pharmacologically active dose. Part 2 is a multiple ascending dose to evaluate safety and anti-HBV activity of repeated doses over 24 weeks.

About ImmTAV molecules and infectious diseases
ImmTAV (Immune mobilising monocolonal TCRs Against Virus) molecules are novel bispecific molecules that, like ImmTAC (Immune mobilising monoclonal TCRs Against Cancer) molecules, are designed to
enable the immune system to recognize and eliminate virally infected cells.
Immunocore is advancing clinical candidates to cure patients with HIV and HBV. The Company aims to achieve a reduction in viral reservoirs to enable sustained control of HIV after stopping
antiretroviral therapy (ART), without the risk of virological relapse or onward transmission. This is known as ‘functional cure’. For the treatment of HBV, the Company aims to achieve sustained loss of circulating viral antigens and markers of
viral replication after stopping medication for people living with chronic hepatitis B.
About Immunocore
Immunocore is a commercial-stage biotechnology company pioneering the development of a novel class of TCR bispecific immunotherapies called ImmTAX – Immune mobilizing monoclonal TCRs Against X disease – designed to treat a broad range of diseases,
including cancer, autoimmune, and infectious disease. Leveraging its proprietary, flexible, off-the-shelf ImmTAX platform, Immunocore is developing a deep pipeline in multiple therapeutic areas, including five clinical stage programs in oncology and
infectious disease, advanced pre-clinical programs in autoimmune disease and multiple earlier pre-clinical programs. Immunocore’s most advanced oncology TCR therapeutic, KIMMTRAK (tebentafusp-tebn), has been approved by the U.S. FDA for the treatment
of HLA-A*02:01-positive adult patients with unresectable or metastatic uveal melanoma (mUM) having demonstrated an overall survival benefit in a randomized Phase 3 clinical trial in metastatic uveal melanoma, a cancer that has historically proven to
be insensitive to other immunotherapies.

provisions of the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical facts, included in this press release are forward-looking statements. These statements include, but are not limited to,
statements regarding: the therapeutic potential of IMC-I109V to be an effective treatment for patients with HBV; the expected clinical benefits of IMC-I109V including its potential as a “functional cure”; anticipated results from the Phase 2 portion of the clinical trial of IMC-I109V and expectations regarding the ability to
recruit and enroll additional patients in the clinical trial of IMC-I109V. Any forward-looking statements are based on management’s current expectations of future events and are subject to a number of
risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in or implied by such forward-looking statements, many of which are beyond the Company’s control. These risks and uncertainties
include, but are not limited to, the impact of the ongoing COVID-19 pandemic and the Omicron variant on the Company’s business, strategy clinical trials and financial position; Immunocore’s ability to maintain regulatory approval of KIMMTRAK;
its ability to execute its commercialization strategy for KIMMTRAK including the timing or likelihood of expansion into additional markets or geographies; its ability to develop, manufacture and commercialize its other product candidates;
commercial supply of KIMMTRAK or any future approved products, and launching, marketing and selling of KIMMTRAK or any future approved products; Immunocore’s ability and plans in continuing to establish and expand a commercial infrastructure

results from required later pre-clinical studies and future clinical trials; actions of regulatory agencies, which may affect the initiation, timing and progress of clinical trials or future regulatory approval; Immunocore’s ability to obtain,
maintain and enforce intellectual property protection for KIMMTRAK or any product candidates it is developing; unexpected safety or efficacy data observed during preclinical studies or clinical trials; clinical trial site activation or
enrollment rates that are lower than expected; changes in expected or existing competition; and the success of Immunocore’s current and future collaborations, partnerships or licensing arrangements. These and other risks and uncertainties are
