Immunocore’s tebentafusp granted Breakthrough Therapy Designation for unresectable or metastatic uveal melanoma from FDA

OXFORDSHIRE, England and CONSHOHOCKEN, Pa. and ROCKVILLE, Md., Feb. 19, 2021 (GLOBE NEWSWIRE) — Immunocore (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 announced that the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation (BTD) to tebentafusp (IMCgp100) for the treatment of HLA-A*02:01-positive adult patients with unresectable or metastatic uveal melanoma (mUM).

Bahija Jallal, Chief Executive Officer of Immunocore, said: “We are delighted that the FDA has granted Breakthrough Therapy Designation for tebentafusp based on the survival benefit from our Phase 3 clinical trial announced in November 2020. There is an urgent need for an approved treatment for this rare and aggressive form of melanoma and we look forward to continuing to work with regulators to bring tebentafusp to patients as quickly as possible.”

In an initial pre-planned interim analysis of a randomized Phase 3 clinical trial (IMCgp100-202) in previously untreated metastatic uveal melanoma, a cancer that has historically proven to be insensitive to other immunotherapies, tebentafusp demonstrated superior overall survival (OS) benefit as a monotherapy. The primary endpoint was achieved when the OS Hazard Ratio (HR) in the intent-to-treat population favored tebentafusp, HR=0.51 (95% CI: 0.36, 0.71); p< 0.0001, over investigator’s choice (82% pembrolizumab; 12% ipilimumab; 6% dacarbazine).

The Breakthrough Therapy Designation is a process designed to expedite the development and review of drugs that are intended to treat a serious condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on a clinically significant endpoint(s).

Tebentafusp has also been granted Fast Track Designation and orphan drug designation from the FDA for uveal melanoma and Promising Innovative Medicine designation under the UK Early Access to Medicines Scheme. Immunocore will be working with the FDA to facilitate submission of a BLA for tebentafusp. If approved, Immunocore believes tebentafusp would be the first new therapy for the treatment of metastatic uveal melanoma in 40 years.

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 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 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 Breakthrough Therapy Designation, Fast Track designation and orphan drug designation by the FDA in the United States and Promising Innovative Medicine (PIM) designation under the UK Early Access to Medicines Scheme for metastatic uveal melanoma.

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.
