Third Quarter 2025 Highlights (including post-period)
KIMMTRAK
The Company’s lead product, KIMMTRAK (tebentafusp), is approved in 39 countries and has been launched in 28 countries globally to date for HLA-A*02:01 positive people with unresectable or metastatic uveal melanoma (mUM). KIMMTRAK continues to be the standard of care in most markets where it is launched.
The Company sees three key growth areas as it plans to expand patient reach for KIMMTRAK, including continued global expansion in mUM, the potential expansion into 2L+ advanced cutaneous melanoma (CM), and the potential expansion into adjuvant uveal melanoma.
Metastatic uveal melanoma
KIMMTRAK net product sales were $103.7 million and $295.5 million for the three and nine months ended September 30, 2025, respectively, representing increases of 29% and 31% respectively, as compared to the same periods in 2024.
18% year-over-year quarterly sales growth in the United States with mean duration of treatment increasing to 14 months.
58% year-over-year quarterly sales growth in Europe and in international regions combined, driven by increased demand and launches in additional markets.
2L+ advanced cutaneous melanoma
The Company is currently enrolling patients in the TEBE-AM registrational Phase 3 trial and expects to complete enrollment in the first half of 2026.
The Phase 3 trial is enrolling three arms: tebentafusp monotherapy, tebentafusp in combination with pembrolizumab, and a control (investigator’s choice of therapy including clinical trials, chemotherapy, or retreatment with anti-PD1 or BRAF therapy). The primary endpoint of the randomized Phase 3 trial is Overall Survival (OS).
There is great unmet need in second- and later-line cutaneous melanoma, with no therapy having shown, to date, an OS improvement post checkpoint inhibitors in a randomized clinical trial. The Company estimates that there is a potential to address up to 4,000 previously treated advanced CM patients.
Adjuvant uveal (or ocular) melanoma
The European Organisation for Research and Treatment of Cancer (EORTC) continues to expand the site footprint of the Phase 3 Adjuvant Trial in Ocular Melanoma (ATOM).
The Company estimates that the HLA-A*02:01 positive, high-risk adjuvant uveal melanoma patient population could be up to 1,200 patients in the US and Europe.
PRAME portfolio
Brenetafusp is the Company’s lead PRAME-A02 ImmTAC bispecific candidate. Brenetafusp is being evaluated in combination with nivolumab in a Phase 3 registrational trial (PRISM-MEL-301) in patients with first-line, advanced cutaneous melanoma, and in a Phase 1/2 clinical trial as monotherapy and in combination across multiple tumor types, including ovarian cancer and non-small cell lung cancer (NSCLC).
PRISM-MEL-301 – First PRAME Phase 3 clinical trial with brenetafusp in first-line advanced cutaneous melanoma
The Independent Data Monitoring Committee (IDMC) has recommended the dose of 160 mcg as the go-forward dose in PRISM-MEL-301, the Company’s registrational Phase 3 trial in first-line, advanced cutaneous melanoma.
The IDMC made the decision following a pre-planned review of safety for all three arms and of efficacy for the two brenetafusp regimens (40 mcg and 160 mcg) in the first 90 patients randomized in the Phase 3 trial. (In 1Q 2025, the IDMC reviewed the safety of the first 30 patients randomized and recommended to continue the study with no changes.)
Patients treated with the dose of 160 mcg will be included in the intent-to-treat analysis for the primary endpoint.
Patients who are receiving 40 mcg have the option to dose-escalate to 160 mcg but will not be included in the intent-to-treat analysis for the primary endpoint.
The Company will now continue with a 1:1 randomization of HLA-A*02:01 positive patients with first-line, advanced or metastatic cutaneous melanoma to brenetafusp 160 mcg + nivolumab or a control arm of either nivolumab or nivolumab + relatlimab.
Despite approved therapies, there remains a need for improved progression-free survival and OS, and there is the potential to address an estimated 10,000 HLA-A*02:01 positive patients in the US and Europe.
Phase 1/2 clinical trial of brenetafusp in multiple solid tumors
The Company continues to evaluate brenetafusp in a Phase 1/2 trial in combination with non-platinum chemotherapies in platinum-resistant ovarian cancer (PROC) and with bevacizumab or with platinum chemotherapy in earlier lines of platinum-sensitive ovarian cancer (PSOC). In the same trial, the Company continues signal detection in metastatic non-small cell lung cancer (NSCLC) cohorts, including brenetafusp in combination with docetaxel and with osimertinib in earlier-line NSCLC.
IMC-P115C (PRAME-A02 Half-Life Extended) & IMC-T119C (PRAME-A24)
The Company is enrolling patients in the Phase 1 dose escalation trial evaluating IMC-P115C in patients with multiple solid tumors.
IMC-R117C (PIWIL1) for colorectal and other gastrointestinal cancers
The Company is enrolling patients in the Phase 1/2 dose escalation trial evaluating IMC-R117C in HLA-A*02:01 positive patients with advanced solid tumors, including colorectal cancer, as a single agent and in combination with standards of care.
ImmTAV candidates for a functional cure in infectious diseases
The Company’s bispecific TCR technology platform has the potential to offer a new approach for the treatment of certain chronic infections and aims to eliminate evidence of remaining virus in circulation after the patient stops taking medication – known as a ‘functional cure’. Two investigational candidates are in Phase 1 or Phase 1/2 trials for people living with human immunodeficiency virus (HIV) and people with chronic hepatitis B infection (HBV).
Phase 1/2 trial of IMC-M113V (Gag-A02) for people living with HIV
Patient enrollment continues at higher doses in the multiple ascending dose part of the Phase 1/2 clinical trial to identify a safe and tolerable dose.
Phase 1 trial of IMC-I109V (Envelope-A02) for people living with HBV or HBV-positive hepatocellular carcinoma
The Company will present the following poster at the 2025 American Association for the Study of Liver Diseases’ Meeting on November 7, 2025:
Title: IMC-I109V, a soluble T cell receptor (TCR) bispecific targeting HBsAg (ENVxCD3), is tolerable and active against hepatitis B in a first-in-human (FIH) single ascending dose (SAD) study (Poster 1185)
Presenting author: Man-Fung Yuen, MD, PhD, DSc
Session: Poster Session Hepatitis B ("1118-1367")
Date and time: Friday November 7, 2025; 8:00 a.m.-5 p.m. ET
Tissue-specific down modulation of the immune system for autoimmune diseases
The key differentiator of the ImmTAAI platform is tissue-specific, down modulation of the immune system, as the candidates suppress pathogenic T cells via PD1 receptor agonism only when tethered to the target tissue.
IMC-S118AI (PPI-A02) for type 1 diabetes
The Company is on track to file a clinical trial application (CTA) or investigational new drug application (IND) for IMC-S118AI (PPI x PD1) in the second half of 2025.
IMC-U120AI (CD1a) for atopic dermatitis as the initial indication – first universal program
The Company plans to file a CTA/IND for IMC-U120AI (CD1a x PD1) in 2026.
Financial Results
For the third quarter ended September 30, 2025, the Company generated net product sales of $103.7 million compared to $80.2 million for the same period in 2024. Sales of KIMMTRAK were $67.3 million in the United States, $33.5 million in Europe, and $2.9 million in the international regions. The increase in net product sales was due to increased volumes in the United States and Europe as well as global country expansion.
For the quarter ended September 30, 2025, research and development (R&D) expenses were $70.6 million compared to $52.8 million for the same period in 2024. The increase was due to preclinical expenses related to the advancement of the Company’s autoimmune programs, including clinical material manufacturing for anticipated Phase 1 initiations, and clinical expenses related to the progression of the Company’s Phase 3 trials, primarily TEBE-AM and PRISM-MEL-301.
For the quarter ended September 30, 2025, SG&A expenses were $39.8 million compared to $35.5 million for the same period in 2024. The increase was primarily due to costs related to business support functions to support the Company’s growing pipeline and global commercial expansion.
Net (loss) for the quarter ended September 30, 2025, was ($0.2) million, as compared to a net profit of $8.7 million for the same period in 2024. Basic and diluted net loss per share was ($0.00) for the quarter ended September 30, 2025, as compared to a basic and diluted net income per share of $0.17 for the same period in 2024.
Cash, cash equivalents and marketable securities were $892.4 million as of September 30, 2025, as compared to $820.4 million as of December 31, 2024. The Company expects to pay approximately $65 million in sales-related rebate accruals in the fourth quarter of 2025.
