ESMO Abstract
https://cslide.ctimeetingtech.com/esmo2024/attendee/confcal/show/session/232#presentation-abstract-895832222418
Abstract
Background
T cell-engaging bispecifics are designed to redirect T cells to cancer antigens. IMA401 is a next-gen T cell engaging receptor (TCER®) combining a high-affinity TCR domain against an HLA-A*02:01-presented MAGEA4/8 peptide, a low-affinity T cell-recruiting antibody and an Fc part for half-life extension. The target peptide exhibits a >5-fold higher density compared to the MAGEA4-derived peptide targeted by other bispecifics or cell therapies.
Methods
This ongoing Phase 1a/1b first-in-human clinical trial evaluates IMA401 in patients (pts) with recurrent/refractory solid tumors. HLA-A*02:01+ and MAGEA4/8+ pts received initially QW then Q2W iv. IMA401 infusions. Primary objectives: MTD and/or RP2D. Secondary objectives: safety, tolerability, PK, initial anti-tumor activity.
Results
As of April 1, 2024, 25 heavily pretreated cancer pts received IMA401 across the first dose levels (DL1-7, 6.6µg-2.5mg). IMA401 showed manageable tolerability with most common (≥30%) treatment-related adverse events being transient lymphopenia (G1-4) and CRS (G1/2). High-grade (G3/4) neutropenia observed at DL7 did not reoccur after the introduction of dexamethasone pre-treatment. MTD/RP2D was not reached and dose escalation is ongoing. Median terminal half-life was 15.0 days. 55% (11/20) of efficacy-evaluable pts treated in the escalation phase, including initial low MABEL-based starting DLs, achieved disease control (SD/PR). Among these were pts with ovarian cancer, sqNSCLC, gastric cancer, HNSCC, melanoma, and neuroendocrine carcinoma. 45% (9/20) of the pts showed shrinkage of target lesions (median -21.7%), including 3 pts with durable confirmed PRs at 4+, 10+ and 11+ months after first infusion.
Conclusions
IMA401 was well tolerated and its single-agent anti-tumor activity was demonstrated by durable objective responses and disease control. The prolonged half-life prompted a switch to treatment every 2 weeks already during dose escalation. The data of this ongoing Phase 1 dose escalation trial provide first clinical PoC for the next-gen half-life extended TCER® format and its potential in multiple solid tumors.

About IMA203
ACTengine® IMA203 T cells is an autologous T cell product with a genetically modified, pairing-enhanced TCR directed against an HLA-A*02-presented peptide derived from preferentially expressed antigen in melanoma (PRAME). This peptide is frequently expressed in a large variety of solid cancers, thereby supporting the program’s potential to address a broad cancer patient population. Immatics’ PRAME peptide is present at a high copy number per tumor cell and is homogeneously and specifically expressed in tumor tissue. The peptide has been identified and characterized by Immatics’ proprietary mass spectrometry-based target discovery platform, XPRESIDENT®. Through its proprietary TCR discovery and engineering platform XCEPTOR®, Immatics has generated a highly specific T cell receptor (TCR) against this target for its TCR-based cell therapy approach, ACTengine® IMA203.
ACTengine® IMA203 TCR-T is currently being evaluated in a Phase 1 trial as IMA203 monotherapy, and as a second-generation IMA203CD8 (GEN2) monotherapy, where IMA203-engineered T cells are co-transduced with a CD8aß co-receptor, thereby leveraging the power of both CD4+ and CD8+ T cells. As previously reported, IMA203 in combination with an immune checkpoint inhibitor has been deprioritized.

About IMA401
IMA401 is Immatics’ most advanced TCER® molecule that targets an HLA-A*02-presented (human leukocyte antigen) peptide derived from two different cancer-associated proteins, melanoma-associated antigen 4 and/or 8 (“MAGEA4/8”). The MAGEA4/8 peptide has been identified and validated by Immatics’ proprietary mass spectrometry-based target discovery platform XPRESIDENT® and is presented at a 5-fold higher copy number per tumor cell than the MAGEA4 peptide targeted in other clinical trials. Following preclinical proof-of-concept data, including complete remissions of transplanted human-derived tumors in xenograft mouse models, the Phase 1 trial investigates IMA401 in patients with tumors of high MAGEA4/8 prevalence, such as squamous non-small cell lung carcinoma (sqNSCLC), small cell lung cancer (SCLC), head and neck squamous cell carcinoma (HNSCC), bladder, uterine, esophageal and ovarian carcinomas, as well as melanoma, sarcoma subtypes and other solid cancer types.
About TCER®
Immatics’ next-generation half-life extended TCER® molecules are antibody-like “off-the-shelf” biologics that leverage the body’s immune system by redirecting and activating T cells towards cancer cells expressing a specific tumor target. The design of the TCER® molecules enables the activation of any T cell in the body to attack the tumor, regardless of the T cells’ intrinsic specificity. Immatics proprietary biologics are engineered with two binding regions: a TCR domain and a T cell recruiter domain. The TCER® format is designed to maximize efficacy while minimizing toxicities in patients. It contains a high-affinity TCR domain that is designed to bind specifically to the cancer target peptide on the cell surface presented by an HLA molecule. The antibody-derived, low-affinity T cell recruiter domain is directed against the TCR/CD3 complex and recruits a patient’s T cells to the tumor to attack the cancer cells. With a low-affinity recruiter aiming for optimized biodistribution and enrichment of the molecule at the tumor site instead of the periphery, TCER® are engineered to reduce the occurrence of immune-related adverse events, such as cytokine release syndrome. In addition, the TCER® format consists of an Fc-part conferring half-life extension, stability, and manufacturability. TCER® are “off-the-shelf” biologics and thus immediately available for patient treatment. They can be distributed through standard pharmaceutical supply chains and provide the opportunity to reach a large patient population without the need for specialized medical centers.

Chessboard with chess pieces and wooden blocks with the word mergers and acquisitions

Cantor Fitzgerald sees another strong year ahead for oncology M&A, with companies focused on antibody drug conjugates, radiopharmaceuticals and T-cell engagers expected to attract increased attention from major drugmakers looking to replenish pipelines.
Impending patent cliffs will be a big motivator for deals. According to Cantor, around $182B in revenue is at risk over the next four years due to patent expirations, with oncology products accounting for 42% of that number.
Several of the industry's biggest are set to lose patent protection by 2029, including Bristol Myers (BMY) Yervoy, Pomalyst and Opdivo; Johnson & Johnson’s (JNJ) Imbruvica; Merck’s (MRK) Keytruda; Pfizer’s (PFE) Ibrance; and Roche’s (OTCQX:RHHBY) Perjeta, according to Cantor.
Meanwhile, the global market for oncology drugs is expected to grow from $180B in 2022 to $323B in 2028, a rate that is “unparalleled to other therapeutics areas,” Cantor said. In comparison, the global biopharmaceutical market is expected to swell from $978B in 2022 to $1.39T in 2028.
Cantor estimates the industry should see between five and 17 acquisition deals this year, noting that three have already been announced to date: J&J/Ambrx (AMAM), Merck/Harpoon (HARP), and Novartis (NVS)/Morphosys (MOR).
The investment bank also pointed out that the pool of potential buyers is fairly deep as pretty much every major drugmaker has a presence in oncology, with Novo Nordisk (NVO) being a notable exception.
So what type of assets will Big Pharma be seeking out?
Cantor still sees a preference for de-risked assets but noted that proof-of-concept data for oncology drugs can often be achieved in Phase 1/2 testing. Drug candidates addressing larger markets, such as breast, lung or colorectal cancer, should be particularly attractive to potential buyers.
While small molecule candidates will probably account for around 50% of the deals, Cantor says complex biologics have been gaining in popularity. The bank sees assets such as antibody drug conjugates, radiopharmaceuticals and T-cell engagers as being particularly attractive acquisition targets this year, while synthetic lethality and TCR therapies could also see increased interest.
Cantor sees several companies in its coverage universe as potentially attracting suitors this year, including Kura (NASDAQ:KURA), Bicycle (NASDAQ:BCYC), Immunocore (NASDAQ:IMCR), ALX Oncology (NASDAQ:ALXO), Arvinas (ARVN), Immatics (IMTX), Verastem (VSTM), Oric (ORIC), and CG Oncology (NASDAQ:CGON).
Potential targets outside of its coverage include Day One (DAWN), Deciphera (DCPH), Erasca (ERAS), Exelixis (EXEL), Fusion (FUSN), Geron (GERN), Ideaya (IDYA), Karyopharm (KPTI), Janux (JANX), Legend Biotech (LEGN), Merus (MRUS), Nuvalent (NUVL), Olmea (OLMA), PMV (PMVP), Relay Therapeutics(RLAY), Revolution Medicines (RVMD), Syndax (SNDX), SpringWorks Therapeutics (SWTX), UroGen (URGN), and Zentalis (ZNTL).
