ZURICH-SCHLIEREN, Switzerland and CONCORD, Mass., March 09, 2023 (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 proteins known as DARPin therapeutics, today announced its corporate highlights and audited financial results for the full year 2022.

“Our focus in 2023 is the advancement of highly differentiated DARPin therapeutic candidates with the potential to show early clinical value. Recently we dosed the first patient with MP0533, our novel tri-specific T-cell engager for the treatment of AML and high risk MDS. We also announced a breakthrough with our Radio DARPin Therapy Platform which enables us to reduce dose-limiting kidney uptake and potentially opens the door for a pipeline of new candidates, of which the first is targeting Delta-like ligand 3 (DLL3). MP0317, our localized CD40 agonist, has reached its top planned dose without limiting side effects, showing a clear differential against conventional systemically active agonists,” said Patrick Amstutz, Ph.D. Molecular Partners’ Chief Executive Officer. “With our ongoing strong cash position, we will continue to advance our DARPin candidates to deliver on our mission to develop solutions only DARPin therapies can offer to patients living with serious diseases."

Research & Development Highlights

Oncology

MP0317
In November 2022, Molecular Partners presented interim results from the ongoing Phase 1 trial of MP0317, the Company’s DARPin candidate targeting fibroblast activation protein (FAP) and CD40, for the treatment of solid tumors at the 37th SITC Annual meeting. These data demonstrated the first clinical observation of tumor-localized CD40 activation provided by MP0317. The candidate was also seen to be safe and well tolerated with no dose-limiting CD40-related systemic toxicities to date, a key limitation presented by other CD40 agonists. MP0317 is designed to resolve these limitations by activating immune cells specifically within the tumor microenvironment through the simultaneous binding of the immune stimulator CD40 as well as FAP, a protein highly expressed within tumors. The dose escalation of the Phase 1 study remains ongoing, with patient recruitment in the dose escalation portion of the of the Phase 1 trial of MP0317 expected to be completed in the first half of 2023.

MP0533
In January 2023, the first patient was dosed in Molecular Partners’ Phase 1 study of MP0533, a novel tri-specific T-cell engager for the treatment of AML and high risk MDS. The first clinical results from this trial are expected by the fourth quarter of 2023. In an oral presentation at the 64th Annual ASH Meeting in December 2022, Molecular Partners presented preclinical results showing MP0533 can induce preferential killing of cells expressing two or three tumor-associated antigens (TAAs) compared to cells expressing a single TAA. MP0533 engages CD3 on T-cells while binding up to three tumor-associated antigens (CD33, CD70, and CD123) on AML cells. By modulating the affinity to each TAA, Molecular Partners designed MP0533 to induce T-cell-mediated killing preferentially when the cancer cells express two or three of the TAAs. This avidity-driven T-cell activation ensures preferential killing of AML cells, which consistently express two or three of the target antigens. At the same time, it is designed to reduce the damage to healthy cells, which tend to express only one of the target antigens, a recurrent issue with other T-cell engagers in AML. MP0533 was demonstrated to activate T-cells and destroy AML cells in samples from newly diagnosed and previously treated AML patients with different TAA expressions. Humanized mouse models confirmed MP0533’s ability to activate intra-tumoral T-cells and control tumor growth. The research also showed that MP0533 was able to directly target and kill leukemic stem cells (LSCs), while sparing a variety of healthy cells including hematopoietic stem cells. The unique safety profile of MP0533 was further supported preclinically by several other parameters including a lower level of cytokine release relative to benchmark mono-targeted T-cell engagers, both in vitro in a whole blood assay and in vivo in the humanized mouse AML models.

Radio DARPin Therapy Platform
In 2022, Molecular Partners progressed its Radio DARPin Therapy Platform by reducing the kidney uptake of DARPin radio conjugates to overcome nephrotoxicity (toxicity in the kidney), the key limitation of protein-based radio therapies. Furthermore, tumor-associated protein Delta-like ligand 3 (DLL3) was selected as the first target of a DARPin-based therapeutic candidate. 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. These attributes, along with their small size, suggest that DARPins represent ideal delivery vectors for therapeutic radionuclides to efficiently target cancer cells with minimal systemic side effects. Molecular Partners is developing DARPin-based therapeutic candidates, both proprietary as well as in collaboration with Novartis. The Company plans to present its research of DARPin therapeutic candidates and their potential differentiation as tumor targeting moieties in the first half of 2023.

Virology

An Emergency Use Authorization (EUA) application was submitted to the U.S. Food and Drug Administration on February 4, 2022 following the successful global EMPATHY clinical study which demonstrated the efficacy and safety of ensovibep, the first DARPin-based antiviral molecule. Ensovibep also demonstrated in vitro efficacy against most Variants of Concern relative to some antibody therapies, a characteristic Molecular Partners intends to continue leveraging in further antiviral candidates. The clinical development of ensovibep was halted in 2022 due to a lack of neutralization activity against omicron subvariants.

Earlier this year, Novartis informed Molecular Partners that it had submitted a request to withdraw ensovibep's EUA from the FDA. The EUA application for ensovibep was withdrawn effective January 25, 2023.

Looking ahead for the virology portfolio, in January 2023 Molecular Partners signed a non-binding letter of intent with Novartis to negotiate a Research Framework Agreement with a primary focus on establishing pandemic preparedness and fighting emerging infectious global health threats.

Ophthalmology

In November 2021, Molecular Partners regained global development and commercial rights to abicipar for the treatment of neovascular age-related macular degeneration (nAMD) and Diabetic Macular Edema (DME). Abicipar completed two positive Phase 3 studies, CEDAR and SEQUOIA, which supported the non-inferior efficacy of its quarterly dosing regimen compared to monthly ranibizumab.

The Company continues to evaluate potential business opportunities for abicipar outside of internal development at Molecular Partners.

Elsewhere, Molecular Partners offers generous benefits spanning from health to retirement planning to its employees, and fosters diversity and inclusion as a key element of its recruitment process.

2022 Operational and Financial Highlights

Following Novartis' payment of CHF 150 million for ensovibep in January 2022, Molecular Partners remains well funded to capture upcoming value inflection points in 2023 and beyond. In the financial year 2022, Molecular Partners recognized total revenues and other income of CHF 189.6 million (2021: CHF 9.8 million) and incurred total expenses of CHF 73.0 million (2021: CHF 73.2 million). This led to an operating profit of CHF 116.6 million for 2022 (2021: Operating loss of CHF 63.4 million). The net financial gain recorded in 2022 was CHF 1.2 million, compared to a net financial loss of CHF 0.4 million in 2021. This resulted in a 2022 net profit of CHF 117.8 million (2021: Net loss of CHF 63.8 million).

The net cash from operating activities in 2022 was CHF 118.6 million (2021: Net cash used of CHF 91.0 million). Including short-term time deposits, the cash and cash equivalents position increased by CHF 116.3 million as compared to year-end 2021, to CHF 249.1 million as of December 31, 2022 (December 31, 2021: CHF 132.8 million). Total shareholders’ equity stood at CHF 235.2 million as of December 31, 2022, an increase of CHF 127.9 million (December 31, 2021: CHF 107.3 million).

The Company's cash position and short-term time deposits of total CHF 249.1 million as per December 31, 2022, continues to provide the Company with financial flexibility and a forecasted cash runway into 2026.

The Company's balance sheet continued to be debt-free in 2022. As of December 31, 2022, the Company employed 175.3 FTE (full-time equivalents), up 7% year-on-year. About 81% of the employees are employed in R&D-related functions.

Key figures as of December 31, 2022

Business outlook and priorities

In 2023, the Company will continue to invest in its clinical stage assets as well as in its development portfolio, particularly in the areas of Radio DARPin therapeutics, oncology, and virology. With initial data from the phase 1 study of MP0533 expected before the end of the year, the potential to further integrate this program as a later stage, wholly-owned asset remains strong. The conclusion of recruitment in the phase 1 study of MP0317 will provide an opportunity to discuss additional combination work with potential collaborators.

As we continue to detail our work in Radio DARPins with presentations at scientific congresses throughout the year, we aim to demonstrate that DARPins can serve as high-affinity tumor targeting therapeutics while providing a high level of kidney protection, a common limiting toxicity associated with other radio therapies. In addition, we continue to remain excited about the prospect of DARPins in virology, within the potential of our own pipeline and with our newly announced letter of intent with Novartis to explore the potential of DARPins in emerging global health threats.

Financial outlook 2023

For the full year 2023, at constant exchange rates, the Company expects total operating expenses of CHF 70-80 million, of which around CHF 9 million will be non-cash effective costs for share-based payments, IFRS pension accounting and depreciation.

Based on the Company's cash position as of December 31, 2022, the Company expects its cash runway to reach into 2026, excluding any potential receipts from R&D partners.
