(OXFORDSHIRE, England & CONSHOHOCKEN, Penn. & ROCKVILLE, Md., US, Wednesday, January 26, 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 announces approval from the United States Food and Drug Administration (FDA) of KIMMTRAK® (tebentafusp-tebn) for the treatment of HLA-A*02:01-positive adult patients with unresectable or metastatic uveal melanoma (mUM).
KIMMTRAK’s approval establishes many firsts as the first TCR therapeutic to receive regulatory approval from the FDA, the first bispecific T cell engager to receive regulatory approval from the FDA to treat a solid tumor, and the first and only therapy for the treatment of unresectable or metastatic uveal melanoma to be approved by the FDA.
Bahija Jallal, Chief Executive Officer of Immunocore, said:“Today’s approval of KIMMTRAKis a historic milestone and the culmination of years of dedication by the Immunocore team, patients, and our healthcare partners. Every year in the United States, hundreds of people are diagnosed with metastatic uveal melanoma who, until now, had no approved treatment options. KIMMTRAK is the first therapy to demonstrate a survival benefit to patients with this disease and we are focused on making KIMMTRAKavailable as quickly as possible.
Dr. Jallal continues, “We’re also proud to have developed the world’s first approved TCR therapeutic, which we believe validates the strength of our platform and opens doors for us to explore further breakthrough discoveries in TCR therapeutics for the treatment of other cancers and diseases with high unmet need.”
“Uveal melanoma is a devastating disease that has historically resulted in death within a year of metastasis for our patients,” said John Kirkwood, MD,director of the Melanoma Center at the UPMC Hillman Cancer Center. “The approval of KIMMTRAK(tebentafusp-tebn) represents a major paradigm shift in the treatment of metastatic uveal melanoma, and for the first time offers hope to those with this aggressive form of cancer.”
The approval of KIMMTRAK is based on the results of Immunocore’s Phase 3 IMCgp100-202 clinical trial, which were published in the September 23, 2021 issue of the New England Journal of Medicine. The randomized pivotal trial evaluated overall survival (OS) of KIMMTRAK compared to investigator’s choice (either pembrolizumab, ipilimumab, or dacarbazine) in patients with previously untreated mUM. 378 patients were randomized in a 2:1 ratio to either KIMMTRAK or investigator’s choice. Data from the trial, the largest Phase 3 trial undertaken in mUM, showed that KIMMTRAK demonstrated unprecedented median OS benefit as a first-line treatment. The OS Hazard Ratio (HR) in the intent-to-treat population favored KIMMTRAK, HR=0.51 (95% CI: 0.37, 0.71); p< 0.0001, over investigator’s choice (82% pembrolizumab; 13% ipilimumab; 6% dacarbazine). In the clinical trials, across both arms, patients stopped treatment for disease progression, unless the patient was otherwise deriving benefit, or for unacceptable toxicity.
“When my husband, Gregg, was diagnosed with metastatic uveal melanoma, it was devastating to learn that there were no treatment options shown to extend life.” said Sara Selig, MD, MPH, Co-Founder and Director of the Melanoma Research Foundation’s (MRF) CURE OM initiative. “Now, for the first time in the history of this disease, we will soon seeextended survival in the next generation of metastatic uveal melanoma patients.”
In the randomized Phase 3 trial of KIMMTRAK (tebentafusp-tebn), treatment-related adverse reactions were manageable and consistent with the proposed mechanism. Among the patients treated with KIMMTRAK, the most common Grade 3 or higher adverse reactions were rash (18%), pyrexia (4%), and pruritus (5%). In the 245 patients treated with KIMMTRAK, Grade 3 cytokine release syndrome (CRS) occurred in <1% of patients and were generally well-managed. There were no Grade 4 or fatal CRS events observed in the Phase 3 trial. A boxed warning is included for CRS as it has the potential to become serious or life-threatening if not managed appropriately.
“Until now, effective treatment options for metastatic uveal melanoma patients were virtually non-existent. The approval of KIMMTRAK represents not only a new therapy but a new hope for the individuals and the families of those diagnosed with the deadliest form of eye cancer,” said Kyleigh LiPira, MBA, CEO of the MRF.
The company is ready to commercialize KIMMTRAK and expects to make the product commercially available in the United States within weeks.
KIMMTRAK was granted Breakthrough Therapy Designation for unresectable or metastatic uveal melanoma by the FDA in February 2021. The Biologics License Application (BLA) approval followed review under the Real-Time Oncology Review (RTOR) program, an initiative of the FDA's Oncology Center of Excellence designed for efficient delivery of safe and effective cancer treatments to patients. The approval was granted four weeks ahead of the assigned PDUFA date of February 23, 2022. Immunocore provided an Assessment AID to facilitate FDA review. KIMMTRAK is being reviewed under the FDA’s Project Orbis initiative, which enabled concurrent review by the health authorities in partner countries that have requested participation.
The European Medicines Agency (EMA), the United Kingdom’s Medicines and Healthcare Regulatory Agency (MHRA), Health Canada, and the Australian Government Department of Health Therapeutic Goods Administration (TGA) have accepted the submission of the Company’s Marketing Authorisation Application. Additionally, Immunocore launched a global early access program to make KIMMTRAK readily available to mUM patients. There are currently over 200 patients in 13 countries in the early access program.
Immunocore is committed to helping patients who need KIMMTRAK obtain access via its KIMMTRAKConnect program. The program provides services with dedicated nurse case managers who provide personalized support, including educational resources, financial assistance, and site of care coordination.

About Uveal Melanoma
Uveal melanoma is a rare and aggressive form of melanoma, which affects the eye. Although it is the most common primary intraocular malignancy in adults, the diagnosis is rare, and up to 50% of people with uveal melanoma will eventually develop metastatic disease. Unresectable or metastatic uveal melanoma typically has a poor prognosis and had no approved treatment until KIMMTRAK.
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.
