ZURICH-SCHLIEREN, Switzerland and CONCORD, Mass., March 14, 2024 (GLOBE NEWSWIRE) -- Ad hoc announcement pursuant to Art. 53 LR Molecular Partners AG (SIX: MOLN; NASDAQ: MOLN), a clinical-stage biotech company developing a new class of custom-built protein drugs known as DARPin therapeutics, today announced its corporate highlights and audited financial results for the full year 2023.

“2023 was a year of successful innovation and execution on our strategy, focusing on novel mechanisms that we believe only DARPin therapies can deliver. The encouraging new clinical and preclinical data across our portfolio illustrate the versatility and differentiated promise of DARPin therapies and our long-term leadership in this field,” said Patrick Amstutz, Ph.D. Molecular Partners’ Chief Executive Officer. “In 2024, we look forward to presenting further clinical data from our lead oncology program MP0533, and translating our significant progress across the Radio-DARPin Therapy and Switch-DARPin platforms into initiation of IND-enabling studies.”

Research & Development

MP0533
In December 2023, the Company presented positive initial data from the first four dosing cohorts of its ongoing Phase 1/2a trial of MP0533 at the 65th American Society of Hematology (ASH) Annual Meeting and Exposition. Results from the first 11 patients treated with MP0533 indicated an acceptable safety profile as of the data cut-off across all four dosing regimens (DRs), with no dose-limiting toxicities observed. Two responders were observed at the time of presentation, including a patient achieving a complete response (CR) in DR 4 and another patient with morphological leukemia-free state (MLFS) in DR 3. These responses are particularly notable for having occurred at dose levels below those predicted as therapeutically active.

MP0533 is a novel tetra-specific T cell-engaging DARPin, which simultaneously targets the antigens CD33, CD123, and CD70 on AML cells as well as the immune activator CD3 on T cells. AML cells display higher co-expression at least two of these target antigens as compared with healthy cells. MP0533 binds with increasing avidity as the number of its target antigens present increases, dramatically favoring binding to AML cells over healthy cells. This unique avidity-driven mode of action is designed to enable T cell-mediated killing of AML cells while preserving a therapeutic window that minimizes damage to healthy cells.

The Phase 1/2a study is on track with dosing in DR 6 currently ongoing. The Company expects to present data from further cohorts receiving MP0533 in H1 2024. Based on current safety and tolerability data from the ongoing study, and based on discussion with treating investigators and key opinion leaders, a protocol amendment is being filed to expand enrollment to additional higher dose cohorts of MP0533 beyond the initially planned highest cohort (DR 7). The goal of the additional higher doses will be to explore the full potential efficacy of MP0533. The Company expects to enroll patients in the added higher cohorts seamlessly in H2 2024.

Switch-DARPin Platform
In 2023, the Company introduced the Switch-DARPin platform and presented data evidencing its mechanism-of-action. The Switch-DARPin platform represents a further evolution of the Company’s capabilities to deliver multispecific candidates to address different disease needs. The Switch-DARPin platform provides a logic-gated “on/off” function (the “Switch”) to multispecific DARPin candidates leading to activation only in the presence of defined antigens. The objective is conditional activation of a targeted immune response.

In January 2024, the first program from the Switch-DARPin platform was introduced at the 42nd Annual J.P. Morgan Healthcare Conference, namely a cKIT x CD16a x CD47 multispecific Switch-DARPin candidate designed as next-generation targeted conditioning regimen for hematopoietic stem cell transplantation (HSCT) in AML and other diseases benefiting from HSCT such as genetic diseases. The cKIT x CD16a x CD47 Switch-DARPin program is designed to induce exhaustive killing of stem cells to increase long-term disease control post HSCT for AML patients, including those with a poor cytogenetic risk profile, and those currently not eligible for standard high-intensity conditioning. Our intent is to extend the access to potentially curative HSCT for more patients with AML and beyond.

The target-by-target rationale for this program’s design is:

  • cKIT is critical for stem cell maintenance and renewal and thus expressed on both hematopoietic and leukemic stem cells.
  • The CD16a DARPin engages NK cells and macrophages to selectively kill cKIT-positive cells.
  • The Switch-DARPin will block the CD47 “don’t eat me” signal only when the molecule binds on cKIT-positive cells, leveraging the power of CD47 inhibition without its associated toxicity to healthy cells.

The Company expects to present initial pre-clinical data from the first Switch-DARPin program cKIT x CD16a x CD47 in H1 2024 and to run preclinical proof-of-concept studies in H2 2024, which should provide strong translational efficacy data.

Radio-DARPin Therapy (RDT) Platform
In September 2023, Molecular Partners presented preclinical data from its RDT platform at the 36th Annual Meeting of the European Association of Nuclear Medicine (EANM) demonstrating a substantially increased tumor uptake of RDT candidates through an adjustment of systemic half-life, achieved by binding to the human serum albumin protein. These results expand on preclinical data that were previously reported at the American Association for Cancer Research (AACR) Annual Meeting and Society of Nuclear Medicine and Molecular Imaging (SNMMI) Annual Meeting in 2023 and highlight that surface engineering of the DARPin backbone into a “Stealth” DARPin can lead to marked reduction of RDT candidate reabsorption by kidneys, addressing a key challenge for protein-based radionuclide delivery vectors. At the 42nd Annual J.P. Morgan Healthcare Conference in January 2024, Molecular Partners presented data showing the reduction of kidney absorption through novel engineered Stealth DARPins as well as enhanced tumor uptake via half-life engineering for several targets. Achieving improved tumor uptake and reduced kidney reabsorption has enabled the expansion of the RDT pipeline and strategy for the RDT portfolio.

Furthermore, in January 2024, Molecular Partners and Orano Med entered a strategic collaboration to co-develop 212Pb-based RDTs for patients with solid tumors. The deal combines the power of DARPins, as a highly differentiated modality for tumor-targeted delivery of radioisotopes, with Orano Med’s leading capabilities in Targeted Alpha Therapy and supply to further advance the RDT platform and expand Molecular Partners’ RDT portfolio.

The tumor-associated protein Delta-like ligand 3 (DLL3) was selected as the target of the Company’s lead RDT program to be advanced into IND-enabling studies in H1 2024. Expression of DLL3 is low in healthy tissue but significantly increased in certain tumor types, providing an opportunity for selective targeting through the high affinity and specificity offered by DARPins. The initiation of clinical studies and first-in-human data are expected in 2025 through co-development with Orano Med. Molecular Partners also expects to nominate additional targets and RDT candidates in 2024.

In addition to the above updates, Molecular Partners continued to progress its RDT portfolio of projects in partnership with Novartis.

MP0317
In November 2023, the Company presented additional positive dose-escalation data from its Phase 1 study of MP0317 in patients with advanced solid tumors at the 38th Annual Meeting of the Society for Immunotherapy of Cancer (SITC). These data from 46 patients corroborated earlier reported findings of MP0317-induced CD40 activation and related remodeling of the tumor microenvironment (TME). At the time of the presentation, MP0317 monotherapy continued to display a favorable safety profile across all dosing cohorts up to the highest planned dose.

MP0317 enables tumor-localized immune activation through simultaneously targeting the immunostimulatory protein CD40 and fibroblast activation protein (FAP). FAP is expressed in high amounts around tumors. Through this proposed mechanism of action, MP0317 is designed to activate immune cells specifically within the tumor microenvironment, potentially delivering greater efficacy with fewer side effects compared to systemic CD40-targeting therapies.

The Company expects to report the full dataset from the Phase 1 study dose-escalation in H1 2024.

About DARPin Therapeutics
DARPin (Designed Ankyrin Repeat Protein) therapeutics are a new class of custom-built protein drugs based on natural binding proteins that open new dimensions of multi-functionality and multi-target specificity in drug design. The flexible architecture, intrinsic potential for high affinity and specificity, small size and high stability of DARPins offer benefits to drug design over other currently available protein-based therapeutics. DARPin candidates can be radically simple, with a single DARPin unit acting as the delivery vector to a specific target; or multispecific, with the possibility of engaging more than five targets, and combining multiple and conditional functionalities in a unique DARPin drug candidate. The DARPin platform is a rapid and cost-effective drug discovery engine, producing drug candidates with optimized properties and high production yields. DARPin therapeutics have been clinically validated across several therapeutic areas and developed through to the registrational stage.
