(NASDAQ: IMTX, “Immatics” or the “Company”), a clinical-stage biopharmaceutical company active in the discovery and development of T cell-redirecting cancer immunotherapies, today provided a business update and reported financial results for the quarter ended June 30, 2024. “It is an exciting time for Immatics as we prepare to reach several major clinical milestones in the second half of the year. Starting with the presentation of the first clinical data on our TCR Bispecific, TCER® IMA401, at ESMO, followed by further data updates from our cell therapy pipeline and the initiation of the IMA203 registration-enabling clinical trial, we look forward to the continued advancement of our product candidates in the coming months,” said Harpreet Singh, Ph.D., CEO and Co-Founder of Immatics. “Patients with advanced solid tumors are in need of transformative therapies that make a meaningful difference in their quality of life. With each clinical milestone we reach, we move one step closer to making an impact in the lives of these patients.” Second Quarter 2024 and Subsequent Company Progress ACTengine® Cell Therapy Program ACTengine® IMA203 and IMA203CD8 (GEN2) monotherapy On May 14, 2024, Immatics provided a data update on IMA203 monotherapy targeting PRAME from the ongoing Phase 1 trial at the recommended Phase 2 dose (RP2D, 1 to 10 billion total TCR-T cells) in 30 heavily pretreated metastatic melanoma patients evaluable for efficacy. As of the data cut-off on April 25, 2024, treatment with IMA203 monotherapy in the efficacy population has demonstrated a confirmed objective response rate (cORR) of 55% (16/29), a disease control rate of 90% (27/30) and tumor shrinkage in 87% (26/30) of patients. Median duration of response (mDOR) was 13.5 months (min 1.2+, max 21.5+ months) including 11 of 16 confirmed objective responses ongoing at data cut-off and longest duration of response ongoing at >21 months after infusion. Confirmed response rates are similar across all melanoma subtypes (56% (9/16) in cutaneous melanoma and 54% (7/13) in other melanoma subtypes). IMA203 has exhibited a favorable tolerability profile (N=65 patients across all dose levels and all tumor types). The next data update, which will include translational and clinical data for IMA203, as well as further details on the clinical trial design for the planned IMA203 Phase 2/3 study, will be presented in 2H 2024 at a medical conference. Immatics is continuing dose escalation of IMA203CD8 (GEN2) with the goal of defining the optimal dose for further development. The next data update for IMA203CD8 (GEN2) is planned for 2H 2024 with a focus on continued dose escalation data in melanoma patients. In addition to treating melanoma patients, Immatics has also started to expand its clinical footprint outside of melanoma to address a broader patient population with a particular focus on ovarian and uterine cancers. TCR Bispecifics Programs Immatics’ T cell engaging receptor (TCER®) candidates are next-generation, half-life extended TCR Bispecific molecules. They are designed to maximize efficacy while minimizing toxicities and provide a patient-convenient dosing schedule through the proprietary format consisting of a high-affinity TCR domain against the tumor target and a low-affinity T cell recruiter binding to the T cell. Upcoming milestones for Immatics’ clinical TCER® pipeline Martin Wermke, M.D. will present the first clinical data from Immatics’ IMA401 (MAGEA4/8) at the ESMO Congress during an oral presentation titled, Initial safety, pharmacokinetics, and anti-tumor activity data of TCER IMA401, a MAGEA4/8-directed half-life extended TCR Bispecific, in Phase 1 dose escalation, on September 16, 2024, at 11:25 CEST. Data from approximately 30 patients from the dose escalation phase will be presented. Key objectives include: (1) Demonstrating tolerability of the novel, next-generation, half-life extended TCR Bispecifics format; (2) optimizing dosing schedule to a less frequent regimen during dose escalation, based on pharmacokinetics data; and (3) demonstrating initial clinical anti-tumor activity. IMA402 (PRAME) data are planned to be announced later in 2H 2024 and will include data from at least 15 patients in early stages of dose escalation across multiple solid cancers, but initially focused on melanoma. TCER® IMA401 (MAGEA4/8) The Phase 1 dose escalation basket trial to evaluate safety, tolerability and initial anti-tumor activity of TCER® IMA401 in patients with recurrent and/or refractory solid tumors is ongoing. IMA401 targets an HLA-A*02:01-presented peptide that occurs identically in two different proteins, MAGEA4 and MAGEA8. This target peptide has been selected based on natural expression in native solid tumors at particularly high target density (peptide copy number per tumor cell identified by Immatics’ proprietary quantitative mass spectrometry engine XPRESIDENT® is >5x higher than for a MAGEA4 peptide target used in other clinical trials). MAGEA4 and MAGEA8 are expressed in multiple solid cancers including lung cancer, head and neck cancer, melanoma, ovarian cancer, sarcoma and others. IMA401 is being developed in collaboration with Bristol Myers Squibb. TCER® IMA402 (PRAME) Immatics initiated the Phase 1/2 trial investigating the Company’s fully owned TCER® candidate IMA402 in patients with recurrent and/or refractory solid tumors in August 2023. Initial focus indications are ovarian cancer, lung cancer, uterine cancer and cutaneous and uveal melanoma, among others. IMA402 targets an HLA-A*02:01-presented peptide derived from the tumor antigen PRAME. This target peptide has been selected based on natural expression in native solid primary tumors and metastases at particularly high target density (peptide copy number per tumor cell identified by Immatics’ proprietary quantitative mass spectrometry engine XPRESIDENT®). Corporate Development In July 2024, Alise Reicin, M.D., was appointed to Immatics’ Board of Directors as the Company is advancing its pipeline of TCR-based cell therapy and bispecific product candidates into the next phase of development. Dr. Reicin brings extensive experience in early- and late-stage clinical development and has led the successful development of multiple important new therapies, including Keytruda®. Second Quarter 2024 Financial Results Cash Position: Cash and cash equivalents as well as other financial assets total €531.1 million ($568.5 million1) as of June 30, 2024, compared to €425.9 million ($455.9 million1) as of December 31, 2023. The increase is mainly due to the public offering in January 2024, partly offset by ongoing research and development activities. The Company projects a cash runway into 2027. Revenue: Total revenue, consisting of revenue from collaboration agreements, was €18.8 million ($20.1 million1) for the three months ended June 30, 2024, compared to €22.4 million ($24.0 million1) for the three months ended June 30, 2023. The decrease is mainly the result of a one-time revenue of €13.7 million associated with an opt-in payment by BMS during the three months ended June 30, 2023. Research and Development Expenses: R&D expenses were €35.2 million ($37.7 million1) for the three months ended June 30, 2024, compared to €27.3 million ($29.2 million1) for the three months ended June 30, 2023. The increase mainly resulted from costs associated with the advancement of the clinical pipeline candidates.General and Administrative Expenses: G&A expenses were €10.1 million ($10.8 million1) for the three months ended June 30, 2024, compared to €9.4 million ($10.1 million1) for the three months ended June 30, 2023. Net Profit and Loss: Net loss was €18.0 million ($19.3 million1) for the three months ended June 30, 2024, compared to a net loss of €24.6 million ($26.3 million1) for the three months ended June 30, 2023. The decrease in net loss despite decreased revenue and increased operating expenses is driven by an increased financial result.
