About resminostat

Resminostat is an orally administered class I, IIb and IV histone deacetylase (HDAC) inhibitor that potentially offers an approach to treating different kinds of cancer. Resminostat demonstrated that it is well tolerated and can inhibit tumor growth and proliferation, cause tumor regression, and strengthen the body’s immune response to cancer.  Resminostat is currently being investigated in a pivotal study in cutaneous T-cell lymphoma (CTCL) as maintenance treatment by 4SC in Europe and by Yakult Honsha in Japan.

About cutaneous T-cell lymphoma (CTCL)

CTCL is a rare disease with approximately 5,000 patients being newly diagnosed in Europe each year. The disease arises from malignant transformation of T-cells, a specialized subgroup of immune cells, primarily affects the skin, but may ultimately involve lymph nodes, blood and visceral organs.

Currently, CTCL is not curable and treatment options for advanced-stage CTCL are limited. Although patients respond to the available treatment options, the duration of response is often short-lived and declines as the severity of the disease increases. The key therapeutic challenge in advanced-stage CTCL is therefore to make remissions more durable by halting disease progression and improving patient’s quality of life.

About the RESMAIN study – resminostat for maintenance treatment of CTCL

The pivotal RESMAIN study is being conducted at more than 50 clinical centers in 11 European countries and Japan. It included 201 patients who suffer from advanced-stage cutaneous T-cell lymphoma (CTCL) that have achieved disease control with systemic therapy. The patients were randomized 1:1 to receive either resminostat or placebo. Patients who experience disease progression – while being on placebo – will be offered resminostat in an open label treatment arm. The primary goal of the study is to determine whether maintenance treatment with resminostat prolongs progression-free survival. The key secondary objective is to prolong the time to symptom worsening (pruritus).

About the concept of maintenance therapy

The pivotal RESMAIN study is focused on patients with advanced-stage, incurable cutaneous T-cell lymphoma (CTCL). Such patients suffer from painful and itchy skin lesions resulting in disfigurement and a severely impaired quality of life. Furthermore, lymph nodes, blood or visceral organs can be involved. The current therapeutic options rarely provide long-lasting responses or stabilization of disease for meaningful periods, with most patients progressing within several months.

Resminostat is being evaluated as maintenance treatment – a unique innovative treatment approach in CTCL (Stadler et al., 2021) - intended to prolong the period patients are stable and not progressing. Furthermore, recent preclinical data suggests that resminostat has the potential to alleviate the itching in CTCL patients, thereby additionally improving their quality of life.

Brain Computer Interface (BCI) Enables Thought-Controlled Walking after Spinal Cord Injury

Pioneering study in Nature demonstrates that adding a BCI to ONWARD® ARC Therapy™ can
enable thought-controlled standing, walking, and stair climbing

EINDHOVEN, the Netherlands — May 24, 2023 — ONWARD Medical N.V. (Euronext: ONWD), the medical technology company creating innovative spinal cord stimulation therapies to restore movement, function, and independence in people with spinal cord injury (SCI), today announces a publication in Nature showing that a wireless brain-computer interface (BCI) can use thought to modulate ARC Therapy. Researchers reported that when paired with ARC Therapy, an implanted BCI allowed an individual to gain augmented control over when and how he moved his paralyzed legs.

“This publication shows the remarkable potential of ARC Therapy to be enhanced with the introduction of a BCI, facilitating more natural movement based on the thoughts of a person living with paralysis,” said Dave Marver, CEO of ONWARD. “We have positioned ONWARD as a leader in the BCI field with our unique understanding of spinal cord stimulation for people with SCI.”

“The BCI establishes a continuous link between movement intentions and spinal cord stimulation, allowing for more natural restoration of mobility,” said neuroscientist Grégoire Courtine, professor at EPFL, and co-author of the Nature paper. “I look forward to working with the ONWARD team to advance this important new technology.”

The data published today are part of an ongoing clinical feasibility study investigating the safety and preliminary effectiveness of brain-controlled spinal cord stimulation after SCI. The study is being coordinated by .NeuroRestore co-Directors – Grégoire Courtine and Jocelyne Bloch, a neurosurgeon at Lausanne University Hospital (CHUV) – as well as Guillaume Charvet, Head of the Medical Device Development Lab at CEA-Leti / Clinatec.

All ONWARD devices and therapies, including but not limited to ARC-IM, ARC-EX, and ARC Therapy, are investigational and not available for commercial use.

Upon FDA approval, Advanced Medical Balloons launches innovative hygh-tec catheter system for ICU stool drainage in U.S. market

Upon FDA approval, Advanced Medical Balloons launches innovative hygh-tec catheter system for ICU stool drainage in U.S. market

• Creative Balloons operates under new name Advanced Medical Balloons (AMB)
• AMB’s microscopically thin polyurethane (PUR) balloon catheter systems address indications in intensive care
• 1st product from the ICU portfolio now launched in U.S.: hygh-tec® enables reliable and contamination-free stool drainage
• Strong performance in Germany, with strong market share growth

Waghaeusel (Germany), May 4, 2023 – Advanced Medical Balloons GmbH (formerly Creative Balloons GmbH), a specialist in medical technology from Waghaeusel near Heidelberg, today announced that the company is expanding its intensive care business to the United States. This is based on the approval which has recently been granted by the U.S. Food and Drug Administration (FDA) for their innovative catheter system hygh-tec®.1, 2 The novel fecal management system hygh-tec provides maximum seal and prevention of fecal leakage in patients receiving intensive care.

“We are delighted that the FDA cleared hygh-tec, which is a major milestone for AMB in accessing the U.S. market. Offering the first product from our unique portfolio in the U.S. for medical supply of ICU patients makes us very proud,” said Frank Gehres, CEO of Advanced Medical Balloons. “hygh-tec’s reliably high leak tightness means a significant reduction in workload and saving time for caregivers. The trans-anal sealing mechanism could also support early mobilization of cardiac patients or contribute to preventing infection in severely burnt patients. For physicians, this smart fecal management opens up novel therapeutic possibilities.”

Along with the start of U.S. sales, the company operates globally as Advanced Medical Balloons (AMB) since April 1, 2023. Advanced Medical Balloons Inc. is based in Atlanta, GA, and is currently establishing its own U.S. sales structure under the leadership of experienced General Manager Kent Johnson. “While building out our commercial team, we have initiated clinical use in ICU patients in the U.S. and are rolling out hygh-tec with intensive care clinicians throughout the country,” said Kent Johnson. “We have already seen very encouraging feedback from healthcare professionals confirming their need for a next-generation fecal management system, and I am extremely positive regarding our commercial success.”

Frank Gehres confirms: “While hygh-tec is already established in its lead market Germany, where we currently have almost a quarter of market share in ICUs and are continuously growing, the USA is the most important market for AMB, globally. With approximately 110,000 intensive care beds, we see a market potential in the mid three-digit million range. I am therefore very pleased that we have been able to win Dr. Ramona Koenig as Chief Operating Officer to support the roll-out of our products and the expansion of our business activities.” Ramona Koenig, a trained physicist with a PhD in physical chemistry, joined AMB on March 1, 2023, from Rottendorf Pharma.

The technical basis for hygh-tec is its innovative design of the elastic and deformable polyurethane catheter tube, which allows an unmatched trans-anal sealing performance. It clings to the rectal mucosa free from tension and spontaneously adapts to the sphincter dynamics and movements of the patient.

By adapting to the current pressure, intelligent synchronization with the sphincter is possible. When the tone decreases and the sphincter muscle opens, the sheath can spontaneously straighten in the anal canal and allows unobstructed defecation.

Immatics Reports Interim Clinical Data from Ongoing Phase 1b Cohort A Monotherapy with ACTengine® IMA203 TCR-T Targeting PRAME

Company to host conference call today, May 2, at 8:30 am EDT / 2:30 pm CEST

  • Update covers data from 11 heavily pre-treated, last-line patients in Phase 1b dose expansion Cohort A treated with IMA203 TCR-T monotherapy against PRAME
  • Objective response rate (ORR): 64% (7/11) initial ORR at week 6 and 67% (6/9) confirmed ORR at month 3
  • Median duration of response not reached at median follow-up time of 8.5 months at data cut-off
  • Objective responses independent of solid tumor type at low, medium and high PRAME expression levels in checkpoint-refractory cutaneous melanoma, platinum-resistant ovarian cancer, uveal melanoma, head and neck cancer and synovial sarcoma
  • Cohort A IMA203 monotherapy TCR-T treatment continues to show manageable tolerability with no high-grade CRS and no ICANS; no dose dependent increase of CRS observed
  • Proprietary rapid manufacturing process with 7 days of manufacturing time; manufacturing success rate of 94% to reach current recommended Phase 2 dose
  • Next data update and pathway towards registration-directed trials planned to be set out in 4Q 2023
  • Company well capitalized with cash position1 of $386m at YE 2022 and reach into 2025 to leverage multi-cancer PRAME opportunity

Houston, Texas and Tuebingen, Germany, May 2, 2023 – Immatics N.V. (NASDAQ: IMTX, “Immatics”), a clinical-stage biopharmaceutical company active in the discovery and development of T cell-redirecting cancer immunotherapies, today announced an interim clinical data update for 11 patients with recurrent and/or refractory solid cancers treated with ACTengine® IMA203 TCR-T monotherapy in the ongoing Phase 1b dose expansion Cohort A. IMA203 TCR-T cells are directed against an HLA-A*02-presented peptide derived from PRAME, a broadly expressed solid cancer target with clinical proof-of-concept for IMA203 demonstrated by Immatics in 2022. Overall, IMA203 showed a high rate of deep and durable objective responses, with a confirmed objective response rate of 67% (6/9), across multiple tumor types, including two confirmed partial responses (cPR) ongoing at more than 9 months after treatment and three additional partial responses ongoing at data cut-off. IMA203 monotherapy continues to be well tolerated in heavily pre-treated patients at doses of up to approximately 9 billion CD8+ TCR-T cells. No high-grade cytokine release syndrome (CRS) and no immune effector cell associated neurotoxicity syndrome (ICANS) were observed in Cohort A at data cut-off.

The data will be presented by Martin Wermke, MD, Professor at the University Hospital Dresden and Coordinating Investigator of the ACTengine® IMA203 TCR-T trial during a conference call today, May 2, at 8:30 am EDT / 2:30 pm CEST.

“The treatment of solid cancer patients who have exhausted all available standard of care options remains a significant challenge. These patients typically show fast progressing disease with very poor prognosis,” said Martin Wermke, MD, Coordinating Investigator of the ACTengine® IMA203 TCR-T trial. “It is therefore very encouraging to see that IMA203 is able to provide durable, clinically relevant responses in a variety of solid cancer patients.”

“Today marks a significant step in our efforts towards bringing our ACTengine® IMA203 monotherapy to patients with solid tumors, as we present for the first time longer-term clinical data demonstrating deep and durable responses, some of them ongoing beyond 9 months after treatment,” commented Cedrik Britten, MD, Chief Medical Officer at Immatics. “Furthermore, we show that these responses are agnostic of tumor type and that ACTengine® IMA203 achieved objective responses at widely differing PRAME expression levels. These data further increase our confidence in the success and broad potential of targeting PRAME, and our product candidate IMA203. We continue executing and anticipate announcing a potential fast-to-market pathway for the first 1-2 indications by the end of the year.”

Safety data for IMA203 TCR-T monotherapy in Phase 1b Cohort A: Treatment with IMA203 monotherapy continues to show manageable tolerability at doses as high as ~9×109 TCR-T cells.

  • At data cut-off on April 4, 2023, 11 PRAME-positive patients were infused with IMA203 TCR-T cells at dose level (DL) 4 or DL5 with a mean total infused dose of 3.67×109 TCR-T cells (range 1.30-8.84×109 TCR-T cells).
  • Based on data review of 6 patients in the exploratory highest DL5, this DL was cleared by the DSMB (Data and Safety Monitoring Board) for safety, and the updated provisional recommended Phase 2 dose (RP2D) now includes DL4 and DL5. The final RP2D will be defined prior to starting Phase 2.
  • Most frequent treatment-emergent adverse events (TEAEs) were as expected for cell therapies.
  • All 11 patients experienced expected cytopenia (Grade 1-4) associated with lymphodepletion. 10 patients (91%) had a low to moderate (Grade 1-2) cytokine release syndrome (CRS), of which 5 patients (45%) had Grade 1, and 5 patients (45%) had Grade 2 CRS. No high-grade (Grade 3 or higher) CRS and no immune effector cell associated neurotoxicity syndrome (ICANS) were observed in any of these 11 patients. No dose-dependent increase of CRS was observed across Phase 1a and Phase 1b Cohort A (N=38 patients infused with IMA203 in total).
  • No additional dose limiting toxicities (DLT) were observed in Cohort A since the initial Phase 1a dose escalation.

Clinical activity for IMA203 TCR-T monotherapy in Phase 1b Cohort A: IMA203 monotherapy demonstrates a high rate of deep objective responses with ongoing durability of more than 9 months after treatment in some patients.

  • At data cut-off on April 4, 2023, 11 patients were infused with IMA203 TCR-T cells and evaluable for at least one tumor response assessment post treatment.
  • Objective responses were observed in last-line solid cancer patients including cutaneous melanoma, ovarian cancer, uveal melanoma, head and neck cancer, synovial sarcoma.
  • Patients were heavily pre-treated with a mean of ~4 lines of prior systemic treatments and had exhausted all available standard of care treatments.
  • All cutaneous melanoma patients were checkpoint inhibitor-refractory, all ovarian cancer patients were platinum-resistant.
  • Initial objective response rate (ORR) of 64% (7/11) was observed at ~week 6 (partial responses, PR, according to RECIST 1.1).
  • Confirmed ORR of 67% (6/9) was observed at ~month 3; initial responses at week 6 were confirmed for all 6 responders with available subsequent 3-month scan.
  • Median duration of response2 was not reached (min 1.3+ months, max 8.8+ months) at a median follow-up3 of 8.5 months.
  • At data cut-off, 5 of 7 responses remain ongoing:
    • 2 cPRs (cut. & uveal melanoma) ongoing at 9+ months
    • 1 cPR (cut. melanoma) ongoing at 6+ months
    • 1 cPR (ovarian cancer) ongoing at ~3 months
    • 1 PR (synovial sarcoma) ongoing at 6+ weeks
  • Objective responses were observed in patients independent of tumor type at all PRAME expression levels above Immatics’ mass spectrometry-guided RNA threshold including expression levels at or just above this threshold.
  • IMA203 T cells were found in all evaluable tumor tissues and the level of tumor infiltration was associated with objective responses.

Best Overall Response – Phase 1b Cohort A

Response over Time – Phase 1b Cohort A

 

Manufacturing of IMA203 TCR-T cells

  • Immatics’ proprietary manufacturing process has a manufacturing time of 7 days (+7-day expedited release testing), with a success rate of 94% in achieving the provisional RP2D.
  • Manufacturing improvements (including monocyte depletion) and higher applied cell doses implemented for the Phase 1b part of the trial led to significantly increased levels of IMA203 T cells in the blood of patients in Phase 1b Cohort A compared to patients in the Phase 1a dose escalation.
  • Immatics is currently building a state-of-the-art facility designed to manufacture ACTengine® IMA203 TCR-T products, as well as other cell therapy candidates, for registration-directed trials and initial commercial supply. Built with flexibility and cost-efficiency in mind, the facility is designed to be scalable via a modular design to accommodate manufacturing demands. The facility is expected to be operational in 2024.

Development strategy to realize the multi-cancer opportunity PRAME

Immatics believes, the results presented today further validate PRAME as one of the most promising solid tumor targets for TCR-based therapies. Immatics’ IMA203 development strategy is based on two pillars aimed initially at a (1) fast-to-market approach and, later at a (2) broad development.

The first objective is to deliver the PRAME-targeted TCR-T cell therapy in 1-2 last-line solid cancer types as fast as possible with a focus on indications with PRAME prevalence above 80% and where clinical proof-of-concept has been demonstrated, such as cutaneous melanoma (potentially bundled with uveal melanoma) and/or ovarian cancer. The buildout of the manufacturing facility will support Immatics’ efforts to maximize speed to market. Immatics plans to start a first Phase 2 trial in 1H 2024, which is intended to be designed as a registration-directed trial.

As a second step, Immatics plans to also expand development to other cancer types, such as uterine cancer, lung cancer, breast cancer, head and neck cancer and other tumor types having a broad patient reach.

An update on all three IMA203 Phase 1b Cohorts and clinical development path for PRAME TCR-T monotherapy towards registration-directed trials and potential commercialization is planned for 4Q 2023.

In addition to ACTengine® TCR-T, Immatics is addressing PRAME-positive cancers with a second therapeutic modality, TCR Bispecifics (TCER®), to leverage the full potential of the multi-cancer opportunity PRAME. Immatics’ TCER® IMA402 is a next-generation, half-life extended TCR Bispecific for which Immatics submitted a clinical trial application (CTA4) to the Paul-Ehrlich-Institute (PEI) on April 14, 2023, to initiate the Phase 1/2 trial. The trial is expected to commence in 2H 2023 with first clinical data planned in 2024.

Both approaches, ACTengine® and TCER®, are distinct therapeutic modalities that have the potential to provide innovative treatment options for a variety of cancer patient populations with different medical needs. Immatics will continue to evaluate which of these therapeutic modalities (ACTengine® vs. TCER® or both) is best suited for each cancer type.

Immatics conference call
Immatics will host a conference call today, May 2nd, 2023, at 8:30 am EDT / 2:30 pm CEST to discuss the clinical data. The webcast and presentation can be accessed directly through this link. Participants may also access the slides presented in the webcast on the Immatics website in the Investors section under “Presentations” at www.investors.immatics.com/events-presentations. A replay of the webcast will be made available shortly after the conclusion of the call and archived on Immatics website for at least 90 days.

About IMA203 and target PRAME
ACTengine® IMA203 T cells are directed against an HLA-A*02-presented peptide derived from preferentially expressed antigen in melanoma (PRAME), a protein 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 homogenously 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 three ongoing Phase 1b dose expansion cohorts in last-line patients: Cohort A IMA203 TCR-T monotherapy, Cohort B IMA203 in combination with an immune checkpoint inhibitor; Cohort B is focused on generating safety data for potential further investigation of a combination approach as a front-line therapy, and Cohort C IMA203CD8 TCR-T monotherapy, where IMA203 engineered T cells are co-transduced with a CD8αβ co-receptor. IMA203CD8 is currently being explored in DL4a (up to 0.8×109 TCR-T cells/m2 BSA).

About ACTengine®
ACTengine® is a personalized cell therapy approach for patients with advanced solid tumors. 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. The approach is also known as TCR-engineered cell therapy (TCR-T). All Immatics’ 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. The ACTengine® Programs are co-funded by the Cancer Prevention and Research Institute of Texas (CPRIT).
