Immatics N.V. (NASDAQ: IMTX; “Immatics”), a clinical-stage biopharmaceutical company active in the discovery and development of T cell redirecting cancer immunotherapies, today reported its financial results for the quarter ended June 30, 2021 and provided a business update on its progress over the reporting period.

“An important development during the second quarter of 2021 was a significant increase in patient enrollment for our ACTengine® programs,” said Harpreet Singh, Ph.D., CEO of Immatics. “Following the positive initial results we provided in the first quarter, we now look forward to announcing more advanced data including safety, biological activity and the assessment of anti-tumor activity for a range of different cancer indications in the second half of 2021.”

“In addition to the upcoming clinical data for our ACTengine® trials, we are excited to move our second therapeutic modality towards the clinic,” added Carsten Reinhardt, M.D., Ph.D., Chief Development Officer at Immatics. “We are encouraged by the entirety of the IMA401 data set, which following discussions with regulatory authorities puts us in a strong position to submit our IMA401 Clinical Trial Application during the fourth quarter of 2021. Our TCER® pipeline is further strengthened by our second TCR Bispecifics program, IMA402, for which we recently presented preclinical proof-of-concept data.”

Second Quarter 2021 and Subsequent Company Progress

Adoptive Cell Therapy Programs

• ACTengine® IMA200 series – Patient recruitment remains on track and the additional trial sites initiated in Europe and the US have supported the acceleration of recruitment. As of end of July, 27 patients have been treated in the IMA200 series. The first-in-human basket trials for IMA201, IMA202 and IMA203 include patients with recurrent and/or refractory solid cancers utilizing TCR-engineered T cells (TCR-T) directed against the cancer targets MAGEA4/A8, MAGEA1 and PRAME, respectively.
• In March 2021, Immatics reported initial safety and biological data as well as data showing first clinical anti-tumor activity for 10 patients enrolled in these trials. Patients were treated at initial dose levels below one billion transduced cells, which was presumed to be sub-therapeutic as per data published from across the industry.
• The next data update, which will cover safety, biological activity, and the assessment of anti-tumor activity across different cancer indications, including patients treated at higher dose levels (dose levels 2 and 3), will be provided by the company within the second half of 2021.

TCR Bispecifics Programs

• IMA401 – Immatics has discussed the proposed clinical trial design for its first TCER® program IMA401, as well as the preclinical data package covering safety and efficacy data in a scientific advisory meeting² with the Paul-Ehrlich Institute, the German regulatory authority. The company also completed the first Good Manufacturing Practices (GMP) production batch delivering a high production yield. IMA401 remains on track for submission of a CTA in the fourth quarter of 2021 and patient recruitment will be initiated in the first half 2022.
• IMA402 – The company presented preclinical proof-of-concept data on IMA402 at the 17^th Annual PEGS Boston Protein Engineering and Cell Therapy Summit in May. IMA402 is directed against a peptide derived from the cancer target PRAME, a protein that is frequently expressed in many solid cancers, thereby supporting the program’s potential to address a broad range of cancer patients and indications. Data demonstrated tumor cell killing in vitro and complete regressions of established tumors in an in vivo tumor model. Immatics has selected a lead candidate for the clinical program and initiated manufacturing activities.

Corporate Development

• As of July 1, 2021, Immatics adopted a one-tier structure for its Board of Directors. As part of this process, the company’s CEO Harpreet Singh, Ph.D., has joined the Board.
• Friedrich von Bohlen und Halbach, Ph.D., was appointed as successor of Christof Hettich, L.L.D. Dr. von Bohlen und Halbach is Managing Partner and co-founder of dievini Hopp BioTech Holding, managing the investments of Dietmar Hopp and family.

Second Quarter 2021 Financial Results

Cash Position: Cash and cash equivalents as well as Other financial assets total €192.8 million ($229.1 million¹) as of June 30, 2021, compared to €216.7 million ($257.5 million¹) as of March 31, 2021.

Revenue: Total revenue, consisting of revenue from collaboration agreements, was €5.2 million ($6.2 million¹) for the three months ended June 30, 2021, compared to €6.9 million ($8.2 million¹) for the three months ended June 30, 2020.

Research and Development Expenses: R&D expenses were €20.3 million ($24.1 million¹) for the three months ended June 30, 2021, compared to €16.5 million ($19.7 million¹) for the three months ended June 30, 2020. The increase is mainly due to expanded clinical activities for the ACTengine® IMA200 series, as well as GMP manufacturing for the TCER® compound, IMA401.

General and Administrative Expenses: G&A expenses were €8.3 million ($9.9 million¹) for the three months ended June 30, 2021, compared to €10.1 million ($12.0 million¹) for the three months ended June 30, 2020. The decrease is mainly due to one-time expenses in connection with the listing of the Company in 2020.

Net Loss: Net loss was €23.8 million ($28.3 million¹) for the three months ended June 30, 2021, compared to €21.3 million ($25.3 million¹) for the three months ended June 30, 2020.

About ACTengine® IMA200 series
Each of the product candidates of the IMA200 series is based on Immatics’ proprietary ACTengine® approach in which the patient’s own T cells are genetically engineered to express a novel, proprietary TCR directed against a defined cancer target. The modified T cells are then reinfused into the patient to attack the tumor, an approach also known as TCR-T. ACTengine® programs IMA201, IMA202 and IMA203 are currently in clinical development for the treatment of solid tumor indications, both in the US and in Germany. All ACTengine® product candidates can be rapidly manufactured utilizing a proprietary manufacturing process designed to enhance T cell engraftment and persistence in vivo.

The ACTengine® T cell products are manufactured at the Evelyn H. Griffin Stem Cell Therapeutics Research Laboratory in collaboration with UTHealth and co-funded by the Cancer Prevention and Research Institute of Texas (CPRIT).

About TCER®
Immatics’ 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. To do so, the proprietary biologics are engineered to have two binding regions. The first region contains an affinity- and stability-improved TCR that binds specifically to the cancer target on the cell surface presented by a human leukocyte antigen (HLA) molecule. The second region is derived from an antibody domain that recruits endogenous T cells to the tumor to become activated. 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. In addition, the TCER® molecule has a Fc-part conferring stability, half-life extension and enhanced manufacturability.
