(OXFORDSHIRE, England & CONSHOHOCKEN, Penn. & ROCKVILLE, Md., US, 10 May 2023) Immunocore Holdings plc (Nasdaq: IMCR), 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, infectious diseases and autoimmune conditions, today announced its financial results for the first quarter ended March 31, 2023, and provided a business update.

“In the first year of launch, we have established KIMMTRAK as the most prescribed medicine for HLA-A*02:01 positive patients with mUM in the US, Germany and France,” commented Ralph Torbay, Head of Commercial of Immunocore. “We continue to work with health authorities and healthcare professionals to bring KIMMTRAK to more patients with mUM around the world, with the goal of extending their lives."

First Quarter 2023 Highlights (including post-period)

KIMMTRAK® (tebentafusp-tebn) for metastatic uveal melanoma (mUM)

KIMMTRAK is approved in over 30 countries globally and commercial expansion continues as we prepare to make the medicine available to even more patients. Total net product revenue (or “net sales”) arising from the sale of KIMMTRAK (tebentafusp) was £42.1 million (or $52.0 million) for the first quarter of 2023, of which £29.5 million (or $36.5 million) was in the United States, £12.3 million (or $15.2 million) in Europe, and £0.2 million (or $0.2 million) in international regions.

During the first quarter of 2023, KIMMTRAK became the most prescribed medicine for HLA*02:01 positive patients with mUM with over half of patients in first line (1L) receiving KIMMTRAK. In addition, the majority of mUM patients in the U.S. were being treated with KIMMTRAK in the community setting.

In France and Germany, an estimated 80% and 70%, respectively, of first line HLA-A*02:01 positive patients with mUM treated in the first quarter received KIMMTRAK. The Company launched KIMMTRAK in Austria and Israel in the first quarter and expects the commercial transition in Italy in the second quarter of this year. The Company expects to launch KIMMTRAK in four additional European countries by the end of 2023.

In April, the Company presented data in HLA-A*02:01+ patients with mUM at the 2023 American Association for Cancer Research (AACR) Annual Meeting. The data demonstrated a correlation between early circulating tumor DNA (ctDNA) reduction and longer overall survival (OS) in the Phase 3 trial with KIMMTRAK (tebentafusp). ctDNA reduction by week 9 was observed in 88% of first-line mUM patients (Phase 3 trial) and 71% in previously treated patients (Phase 2 trial). ctDNA clearance was also higher in first-line patients (37%) compared to second-line patients (13%). In both trials, this reduction was associated with longer OS. The Company presented additional data with tebentafusp including a final analysis, at almost 4 years of follow-up, from the Phase 2 trial, tumor response in orbital lesions, and in vitro data assessing direct and indirect mechanisms of tumor control from TCR-CD3 bispecifics in melanoma.

The Company had two abstracts accepted for poster presentation at the upcoming 2023 American Society of Clinical Oncology (ASCO) Annual Meeting taking place June 2-6, 2023 in Chicago, IL:

Title: Early ctDNA reduction may identify patients with stable disease and long OS on tebentafusp

• Presenting author: Dan Feng
• Session: Melanoma/Skin cancers
• Date & time: 3 June – 1:15-4:15 p.m. CT
  
  

Title: A Phase 2/3 trial in progress on tebentafusp as monotherapy and in combination with pembrolizumab in HLA-A*02:01+ patients with previously treated advanced non-uveal melanoma (TEBE-AM)

• Presenting author: Diwakar Davar
• Session: Melanoma/Skin cancers (Trial in Progress)
• Date & time: 3 June – 1:15-4:15 p.m. CT
  
  

Tebentafusp Phase 2 / 3 trial in advanced melanoma

The Company has started randomizing in its Phase 2/3 clinical trial of tebentafusp in patients with previously treated advanced melanoma. The trial is randomizing patients with advanced melanoma, excluding uveal melanoma, who have progressed on an anti-PD1, received prior ipilimumab and, if applicable, received a BRAF kinase inhibitor. Patients will be randomized to one of three arms including tebentafusp, as monotherapy or in combination with an anti-PD1, and a control arm. The Phase 2 portion of the trial will include 40 patients per arm and has a dual primary endpoint of overall survival (OS) and ctDNA reduction.

IMC-F106C targeting PRAME-A02 in multiple solid tumors

The Company is continuing to expand the clinical trial footprint for PRAME-A02 trial enrolling patients into the Phase 1/2 monotherapy and combination arms across multiple tumor types, including the four expansion arms for patients with advanced ovarian, non-small cell lung, endometrial, and melanoma cancers. The Company expects to report data from the monotherapy and combination arms by the first half of 2024.

Expansion of PRAME franchise: IMC-T119C (PRAME-A24) & IMC-P115C (PRAME-A02 HLE)

In January 2023, the Company revealed the addition of two new PRAME ImmTAC candidates IMC-T119C (PRAME-A24) and IMC-P115C (PRAME-A02 HLE) for solid tumors to the pipeline. The Company plans to submit investigational new drug applications (INDs) or clinical trial applications (CTAs) for these two ImmTAC candidates in 2024.

First-in-class ImmTAC candidate – IMC-R117C (PIWIL1)

In January 2023, the Company announced the addition of IMC-R117C to the pipeline, an ImmTAC targeting a novel protein for colorectal and other gastrointestinal cancers. The Company believes IMC-R117C is the first PIWIL1 targeted immunotherapy and plans to submit an IND / CTA in the fourth quarter of 2023.

IMC-M113V: aiming for a functional cure for HIV

In February 2023, the Company presented initial safety and pharmacodynamic activity data with IMC-M113V, the first soluble TCR therapy for people living with Human Immunodeficiency Virus (HIV), at the 2023 Conference on Retroviruses and Opportunistic Infections (CROI). Five out of the ten participants who received the 15-mcg dose showed a >4-fold rise in IL6, which had been prespecified as indicative of pharmacodynamic activity based on the Company’s experience in oncology clinical trials with ImmTAC therapies.

The Company has started enrolling people living with HIV in the multiple ascending dose (MAD) part of the trial, to identify a safe and tolerable dosing schedule. This study will also test whether IMC-M113V could lead to reduction in the viral load and, after stopping all therapies (antiretroviral therapies and ImmTAV), delay or prevent HIV rebound (known as functional cure). The MAD trial will enroll up to 28 participants.

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 approved for the treatment of HLA-A*02:01-positive adult patients with unresectable or metastatic uveal melanoma in the United States, European Union, Canada, Australia, and the United Kingdom.

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.
