FDA grants Priority Review to tebentafusp for the treatment of HLA-A*02:01-positive patients with metastatic uveal melanoma; with an expected Prescription Drug User Fee Act (PDUFA) target action date of February 23, 2022
EMA Committee for Medicinal Products for Human Use accepted tebentafusp Marketing Authorization Application and will review under Accelerated Assessment Procedure
OXFORDSHIRE, UK & CONSHOHOCKEN, PA & ROCKVILLE, MD, USA I August 24, 2021 IImmunocore Holdings Plc (Nasdaq: IMCR), a late-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, infectious and autoimmune disease, today announces that regulators in the United States and European Union have each accepted applications for the approval of tebentafusp (IMCgp100) for the treatment of HLA-A*02:01-positive adult patients with metastatic uveal melanoma (mUM).
The U.S. Food and Drug Administration (FDA) has accepted for review Immunocore’s Biologics License application (BLA) for tebentafusp (IMCgp100). The FDA has granted Priority Review to the Company’s BLA submission, a designation for drugs which, if approved, may provide significant improvements in the safety and effectiveness of the treatment of serious conditions. Priority Review designation shortens the review period from the standard ten months to six months from the filing acceptance of the BLA, and therefore, an expected PDUFA target action date of February 23, 2022.
The BLA was initiated and will be reviewed under the Real-Time Oncology Review (RTOR) pilot program, an initiative of the FDA’s Oncology Center of Excellence which is designed to expedite the delivery of safe and effective cancer treatments to patients. Tebentafusp is also being reviewed under the FDA’s Project Orbis initiative, which enables concurrent review by the health authorities in partner countries that have requested participation. Previously, the FDA has granted Breakthrough Therapy Designation (BTD) to tebentafusp for the treatment of HLA-A*02:01-positive adult patients with unresectable or metastatic uveal melanoma.
The European Medicines Agency (EMA)’s Committee for Medicinal Products for Human Use (CHMP), accepted Immunocore’s Marketing Authorization Application (MAA). The EMA has also agreed to the Company’s request for accelerated assessment of its MAA based on the determination that tebentafusp is a product of major interest for public health and therapeutic innovation. Accelerated assessment potentially reduces the time frame for the CHMP and Committee for Advanced Therapies (CAT) to review the Company’s submitted MAA for advanced therapies. While the CHMP review period of a MAA can take up to 210 days, the accelerated assessment reduces the timeframe for review of the MAA to 150 days (excluding clock-stops).
The regulatory submissions are based on data from the randomized Phase 3 IMCgp100-202 clinical trial evaluating tebentafusp in previously untreated metastatic uveal melanoma, a cancer that has historically proven to be frequently insensitive to other immunotherapies. In the final trial analysis, tebentafusp demonstrated clinically and statistically significant superior overall survival (OS) benefit as a monotherapy. The primary endpoint was achieved with the OS Hazard Ratio (HR) in the intent-to-treat population favoring tebentafusp, HR=0.51 [95% CI (0.37, 0.71); p< 0.0001] over investigator’s choice (82% pembrolizumab; 12% ipilimumab; 6% dacarbazine).
Bahija Jallal, Chief Executive Officer of Immunocore, said: “There is an urgent need for an approved treatment for metastatic uveal melanoma, an aggressive form of cancer for which there are very limited treatment options. We are excited to work with the FDA and EMA to bring tebentafusp to patients as quickly as possible.”
About Immunocore
Immunocore is a late-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, infectious and autoimmune. 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 therapeutic candidate, tebentafusp, has 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.
About Tebentafusp
Tebentafusp is a novel bispecific protein comprised of a soluble T cell receptor fused to an anti-CD3 immune-effector function. Tebentafusp specifically targets gp100, a lineage antigen expressed in melanocytes and melanoma, and is the first molecule developed using Immunocore’s ImmTAC technology platform designed to redirect and activate T cells to recognise and kill tumour cells. Tebentafusp has been granted Priority Review; Real Time Oncology Review; Breakthrough Therapy designation; Fast Track designation; and orphan drug designation by the FDA in the United States; orphan drug status in the European Union; and Promising Innovative Medicine (PIM) designation under the UK Early Access to Medicines Scheme for metastatic uveal melanoma. Tebentafusp has also been granted accelerated assessment by the EMA’s Committee for Medicinal Products for Human Use (CHMP). Tebentafusp is being reviewed under the FDA’s Project Orbis initiative, which enables concurrent review by the health authorities in partner countries that have requested participation.

About ImmTAC® Molecules
Immunocore’s proprietary T cell receptor (TCR) technology generates a novel class of bispecific biologics called ImmTAC (Immune mobilising monoclonal TCRs Against Cancer) molecules that are designed to redirect the immune system to recognise and kill cancerous cells. ImmTAC molecules are soluble TCRs engineered to recognise 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 tumours, the ImmTAC mechanism of action holds the potential to treat hematologic and solid tumours, regardless of mutational burden or immune infiltration, including immune “cold” low mutation rate tumours.
About Uveal Melanoma
Uveal melanoma is a rare and aggressive form of melanoma, which affects the eye. Metastatic uveal melanoma typically has a poor prognosis and has no currently accepted optimal management or treatment. Although it is the most common primary intraocular malignancy in adults, the diagnosis is rare, with approximately 8,000 new patients diagnosed globally each year (1,600-2,000 cases per year in the United States). Up to 50% of people with uveal melanoma will eventually develop metastatic disease. When the cancer spreads beyond the eye, only approximately half of patients will survive for one year.
