(OXFORDSHIRE, England & CONSHOHOCKEN, Penn. & ROCKVILLE, Md., US, 11 May 2022) Immunocore Limited (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 its financial results for the first quarter ended March 31, 2022 and provided a business update.

Bahija Jallal, Chief Executive Officer of Immunocore, said: “This has been an exciting start to the year for Immunocore, during which we have continued to establish ourselves as a pioneer in TCR therapeutics. Our gp100 and CD3 targeting ImmTAC, KIMMTRAK, the first in this new class of TCR treatments for cancer and other diseases, has now received regulatory approval for the treatment of unresectable or metastatic uveal melanoma in the United States and European Union. We look forward later this year to exploring KIMMTRAK in cutaneous melanoma and to learning more about the broader potential of our TCR platform with data readouts from our programs targeting PRAME and MAGE.”

Ralph Torbay, Head of Commercial, said: “KIMMTRAK is now approved in 30 countries globally. In the U.S., we have successfully transitioned all early access patients onto commercial product and our team is working closely with healthcare providers to change medical practice and rapidly identify new eligible patients who could benefit from KIMMTRAK. Furthermore, we were delighted that the U.S. National Comprehensive Cancer Network (NCCN) has added KIMMTRAK to the Clinical Practice Guidelines as a Category 1 treatment for unresectable or metastatic uveal melanoma, effectively positioning KIMMTRAK as a standard of care. In Europe, KIMMTRAK is now being promoted in Germany and France, and we expect launches to follow in additional priority countries.”

First Quarter2022Highlights (including post-period)

KIMMTRAK® (tebentafusp-tebn)

In January, the U.S. Food and Drug Administration (FDA) approved KIMMTRAK (tebentafusp-tebn) for the treatment of patients with unresectable or metastatic uveal melanoma (mUM). KIMMTRAK is the first TCR therapeutic, the first bispecific T cell engager to treat a solid tumor, and the first and only therapy for the treatment of unresectable or mUM to receive approval from the FDA.

In February, the Committee for Medicinal Products for Human Use, or CHMP, of the European Medicines Agency, or the EMA, adopted a positive opinion recommending the approval of KIMMTRAK for the treatment of HLA-A*02:01-positive adult patients with unresectable or mUM.

In March, Immunocore successfully transitioned all patients from U.S. early access program (EAP) onto commercial supply. KIMMTRAK was commercially available less than four weeks after FDA approval.

For the first quarter ended, March 31, 2022, Immunocore reported combined net KIMMTRAK and pre-product revenues of £10.5 million (or $13.8 million). U.S. net product revenue from the sale of KIMMTRAK in the first quarter was £7.7 million (or $10.1 million), this is largely due to the successful transition of patients from the EAP onto commercial supply. Pre-product revenue in France for the first quarter was £2.8 million (or $3.7 million).

In April, the EC approved KIMMTRAK (tebentafusp) for the treatment of HLA-A*02:01-positive adult patients with unresectable or metastatic uveal melanoma (mUM). With this approval, KIMMTRAK has received marketing authorisation in all European Union, or EU, member states, and following completion of related national procedures, will also be eligible for sale in Iceland, Liechtenstein, and Norway. We plan to pursue regulatory approval for the marketing authorization of KIMMTRAK in all 27 member states of the EU. Following the approval of KIMMTRAK in the EU, the Company plans to transition patients from the early access programs. There are currently over 130 patients on EAP in the EU and UK.

In April, KIMMTRAK was added as a recommended Category 1 treatment in the latest National Comprehensive Cancer Network® (NCCN®) Clinical Practice Guidelines in Oncology for metastatic uveal melanoma (mUM). NCCN publishes evidence-based guidelines that are followed by many healthcare professionals in the U.S. and globally.

In May, the Company began the commercial launch of KIMMTRAK in Germany. The company has begun transitioning patients from the EAP onto commercial supply and enabling the identification of new patients.

Financial Results

Basic and diluted loss per share was £0.37 (or $0.48) for the three months ended March 31, 2022 compared to £0.76 for the three months ended March 31, 2021. Total operating loss for the three months ended March 31, 2022 was £16.5 million (or $21.6 million) compared to £31.9 million for the same period last year.

Total revenue for the three months ended March 31, 2022 was £22.5 million (or $29.6 million), as compared to £8.3 million for the three months ended March 31, 2021. Revenue in the three months ended March 31, 2022 consisted of net product revenue from the sale of KIMMTRAK in the United States, net pre-product revenue under a compassionate use and an early access program in France, and collaboration revenue. Revenue in the three months ended March 31, 2021 was generated solely from the Group’s collaborations.

Net product revenue from the sale of KIMMTRAK in the three months ended March 31, 2022 was £7.7 million (or $10.1 million) following FDA approval in January 2022. This is largely due to the successful transition of patients from the EAP in the U.S. to commercial supply. Net pre-product revenue for the first quarter was £2.8 million (or $3.7 million). Collaboration revenue increased by £3.7 million to £12.0 million (or $15.7 million) in the three months ended March 31, 2022 compared to £8.3 million for the three months ended March 31, 2021, primarily due to the recognition of remaining revenue under the Lilly Collaboration following termination of the agreement in the three months ended March 31, 2022.

For the three months ended March 31, 2022, our research and development (“R&D”) expenses were £18.6 million (or $24.4 million), respectively, as compared to £19.9 million for the three months ended March 31, 2021. The reduction was driven by lower R&D costs incurred in relation to tebentafusp following the launch of KIMMTRAK.

For the three months ended March 31, 2022, our administrative expenses were £20.1 million (or $26.4 million), respectively, compared to £20.2 million for the three months ended March 31, 2021.

Cash and cash equivalents were £205.9 million or approximately $270.7 million as of March 31, 2022 compared to £237.9 million as of December 31, 2021.

About KIMMTRAK®
KIMMTRAK is a novel bispecific protein comprised of a soluble T cell receptor fused to an anti-CD3 immune-effector function. KIMMTRAK specifically targets gp100, a lineage antigen expressed in melanocytes and melanoma. This is the first molecule developed using Immunocore’s ImmTAC technology platform designed to redirect and activate T cells to recognize and kill tumor cells. KIMMTRAK has been granted Breakthrough Therapy Designation, Fast Track designation and orphan drug designation by the FDA in the United States, Accelerated Assessment by the EMA, and Promising Innovative Medicine (PIM) designation under the UK Early Access to Medicines Scheme for metastatic uveal melanoma.

About Phase 3 IMCgp100-202 Trial
The IMCgp100-202 (NCT03070392) is a randomized pivotal trial that evaluated overall survival (OS) of KIMMTRAK (tebentafusp-tebn) compared to investigator’s choice (either pembrolizumab, ipilimumab, or dacarbazine) in HLA-A*02:01-positive adult patients with previously untreated mUM. KIMMTRAK demonstrated an unprecedented OS benefit with a Hazard Ratio (HR) in the intent-to-treat population favoring KIMMTRAK, HR=0.51 (95% CI: 0.37, 0.71); p< 0.0001, over investigator’s choice (82% pembrolizumab; 13% ipilimumab; 6% dacarbazine).

IMPORTANT SAFETY INFORMATION

Cytokine Release Syndrome (CRS), which may be serious or life-threatening, occurred in patients receiving KIMMTRAK. Monitor for at least 16 hours following first three infusions and then as clinically indicated. Manifestations of CRS may include fever, hypotension, hypoxia, chills, nausea, vomiting, rash, elevated transaminases, fatigue, and headache. CRS occurred in 89% of patients who received KIMMTRAK with 0.8% being grade 3 or 4. Ensure immediate access to medications and resuscitative equipment to manage CRS. Ensure patients are euvolemic prior to initiating the infusions. Closely monitor patients for signs or symptoms of CRS following infusions of KIMMTRAK. Monitor fluid status, vital signs, and oxygenation level and provide appropriate therapy. Withhold or discontinue KIMMTRAK depending on persistence and severity of CRS.

Skin Reactions

Skin reactions, including rash, pruritus, and cutaneous edema occurred in 91% of patients treated with KIMMTRAK. Monitor patients for skin reactions. If skin reactions occur, treat with antihistamine and topical or systemic steroids based on persistence and severity of symptoms. Withhold or permanently discontinue KIMMTRAK depending on the severity of skin reactions.

Elevated Liver Enzymes

Elevations in liver enzymes occurred in 65% of patients treated with KIMMTRAK. Monitor alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total blood bilirubin prior to the start of and during treatment with KIMMTRAK. Withhold KIMMTRAK according to severity.

Embryo-Fetal Toxicity

KIMMTRAK may cause fetal harm. Advise pregnant patients of potential risk to the fetus and patients of reproductive potential to use effective contraception during treatment with KIMMTRAK and 1 week after the last dose.

The most common adverse reactions (≥30%) in patients who received KIMMTRAK were cytokine release syndrome, rash, pyrexia, pruritus, fatigue, nausea, chills, abdominal pain, edema, hypotension, dry skin, headache, and vomiting. The most common (≥50%) laboratory abnormalities were decreased lymphocyte count, increased creatinine, increased glucose, increased AST, increased ALT, decreased hemoglobin, and decreased phosphate.

About ImmTAC® Molecules
Immunocore’s proprietary T cell receptor (TCR) technology generates a novel class of bispecific biologics called ImmTAC (Immune mobilizing monoclonal TCRs Against Cancer) molecules that are designed to redirect the immune system to recognize and kill cancerous cells. ImmTAC molecules are soluble TCRs engineered to recognize intracellular cancer antigens with ultra-high affinity and selectively kill these cancer cells via an anti-CD3 immune-activating effector function. Based on the demonstrated mechanism of T cell infiltration into human tumors, the ImmTAC mechanism of action holds the potential to treat hematologic and solid tumors, regardless of mutational burden or immune infiltration, including immune “cold” low mutation rate tumors.

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.
