Outlook: Funded into 2026 with cash and short-term deposits of CHF 174.1 million; total operating expenses of CHF 70-80 million expected for 2024

ZURICH-SCHLIEREN, Switzerland and CONCORD, Mass., May 16, 2024 -- Ad hoc announcement pursuant to Art. 53 LR Molecular Partners AG (SIX: MOLN; NASDAQ: MOLN), a clinical-stage biotech company pioneering the design and development of DARPin therapeutics for medical challenges that other drug modalities cannot readily address ("Molecular Partners" or the "Company"), today announced corporate highlights and unaudited financial results for the first quarter of 2024.
“This quarter we demonstrated continued progress across our clinical and preclinical pipeline with preparations underway for two new clinical candidates and first-in-human data for our Radio DARPin platform in 2025.” said Patrick Amstutz, Ph.D., Molecular Partners’ Chief Executive Officer. “Building on encouraging initial data and clinical activity, MP0533 dose escalation will expand and now explore higher potential doses, to see what the true clinical impact can be and which patient subpopulations can benefit most. We plan to share data from these higher dose clinical cohorts starting in the second half of this year. For our emerging pipeline, we plan to announce preclinical data from our Switch-DARPin Platform at EHA and anticipate translational efficacy data in the second half of 2024. Our lead Radio-DARPin candidate is advancing into IND-enabling studies in collaboration with our partner Orano Med, with initiation of clinical studies planned for 2025 and pre-clinical data to be presented at SNMMI in June 2024.”
Financial and Business Outlook
For the full year 2024, at constant exchange rates, the Company expects total operating expenses of CHF 70-80 million, remaining consistent with the prior year. Of this figure, approximately CHF 8 million will be non-cash effective costs for share-based payments, IFRS pension accounting and depreciation.
With CHF 174.1 million in cash and short-term time deposits and no debt as of March 31, 2024, the Company expects to be funded well into 2026. This guidance does not include any potential receipts from R&D partnerships.


Research & Development Highlights
MP0533: Clinical update and planned dose escalation expansion
MP0533 (CD33 x CD123 x CD70 x CD3), a novel tetra-specific T cell-engaging DARPin, is currently being evaluated in a Phase 1/2a clinical trial for patients with relapsed/refractory acute myeloid leukemia (r/r AML) and myelodysplastic syndrome/AML (MDS/AML) (NCT05673057).
Results presented at the American Society of Hematology (ASH) Annual Meeting 2023 from the first 11 patients treated with MP0533 indicated a favorable safety profile across the first four dosing regimens (DRs), with no dose-limiting toxicities observed. The study is on track with DR 7 enrollment complete and dosing currently ongoing. Based on the current MP0533 safety data and discussion with treating physicians and key opinion leaders, a protocol amendment was filed on April 25, 2024 to expand enrollment to higher dose cohorts (DRs 8-11) for further characterization of the MP0533 dose-response. The company expects to enroll patients in higher cohorts seamlessly in the second half of 2024.
The mechanism of action of MP0533 is designed to preferentially kill AML cells (blasts and leukemic progenitor and stem cells) that express any combination of the cell surface antigens CD33, CD123, and CD70, while sparing healthy cells which tend to express only one or none of these targets. Updated data, with cut-off as of March 12, 2024, show that MP0533 continues to demonstrate clinical activity similar to what has been reported in earlier dose cohorts. In DRs 5 and 6, an additional 17 patients were treated with MP0533, and of these, 2 patients reached ELN criteria of Morphological Leukemia Free State (MLFS), with additional patients showing early blast reductions in the bone marrow. The drug safety profile remains acceptable with the majority of adverse events reported as infusion-related reactions and cytokine release syndrome. The current data supports expansion to higher dose cohorts to explore the activity of MP0533 in a highly heterogeneous r/r AML patient population. Diverse parameters (e.g., leukemic stem cells, clonal evolution, immune activation) are being examined to inform the next development steps including the potential of earlier lines of treatment, and combination settings. The Company anticipates providing a next clinical update from the study in the second half of 2024 at a scientific congress.

Radio-DARPin Therapy Platform
Molecular Partners continues to advance its RDT platform and programs. At the J.P. Morgan Healthcare Conference in January 2024, the company presented data demonstrating successful increase of tumor uptake and reduction of kidney absorption by applying novel engineering approaches to modify the DARPin backbone (Stealth-DARPins) and its half-life. This enabled further internal progress of the RDT platform and pipeline expansion.
Also in January 2024, Molecular Partners entered a strategic collaboration with Orano Med to co-develop 212Pb-based RDTs for patients with solid tumors. The collaboration 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 the first half of 2024. The initiation of

clinical studies and first-in-human data for our RDT platform are expected in 2025 through co-development with Orano Med.
Molecular Partners will provide an update in an oral presentation at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) Annual Meeting 2024 in Toronto on June 11.
Abstract Title: Lead-212 Radio-DARPin Therapeutic (RDT) targeting delta-like ligand 3 (DLL3) shows promising preclinical antitumor efficacy and tolerability in small cell lung cancer (SCLC)
Session Title: Integrated Session: Radionuclides (CMIIT/RPSC)
Presentation Timing: June 11, 2024; 8:00-9:15 am local time
Molecular Partners also expects to nominate additional targets and RDT candidates in 2024.
In addition, Molecular Partners continued to progress its RDT portfolio of projects in partnership with Novartis.
Switch-DARPin Platform
The Switch-DARPin platform provides a logic-gated “on/off” function (the “Switch”) to multispecific DARPin candidates leading to target activation only in the presence of defined antigens. The objective is conditional activation of a targeted immune response. The first Switch-DARPin program (cKIT x CD16a x CD47) was introduced at the annual J.P. Morgan Healthcare Conference in January 2024. This approach is designed to induce exhaustive killing of hematopoietic stem cells as next-generation conditioning regimen to increase long-term disease control post hematopoietic stem cell transplant (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 as well as additional hematologic malignancies, and genetic diseases requiring HSC transplant.
The company will present initial preclinical data at the European Hematology Association (EHA) Congress 2024 in Madrid on June 14 and has planned preclinical proof-of-concept studies for the second half of 2024.

MP0317: Final Phase 1 data at ASCO
MP0317 simultaneously targets CD40 and fibroblast activation protein (FAP) to enable tumor-localized immune activation. The phase 1 dose-escalation study of MP0317 in patients with advanced solid tumors (NCT05098405) was completed in January 2024. The final outcomes of the 46 treated patients will be presented at the American Society of Clinical Oncology (ASCO) Annual Meeting 2024 in Chicago, IL on June 1.

5.    Other explanatory notes
5.1    Revenue and other group-wide disclosures
On January 5, 2024 the Group announced it entered into a co-development agreement with Orano Med to co-develop 212Pb-based Radio Darpin Therapies (RDT). Under the terms of the co-development agreement, Molecular Partner’s previously disclosed RDT target DLL3 (delta-like ligand 3) will be included in the collaboration with Orano Med. Both companies are developing additional radioligand therapy candidates in partnership with other companies, with Molecular Partners having announced its first collaboration with Novartis in December 2021.
Molecular Partners maintains the option to explore DLL3 for targeted therapy outside of the radiotherapy space. Both companies agree to share the cost of preclinical and clinical development with additional commitments to supply their respective materials.
On December 14, 2021, the Group announced entering into a License and Collaboration Agreement with Novartis to develop DARPin-conjugated radioligand therapeutic candidates for oncology. The Group is able to recharge Novartis its employee related expenses associated with the research activities. During the three months ended March 31, 2024, the Group recognized as revenue an amount of TCHF 311 in relation to this recharge (three months ended March 31, 2023: TCHF 386).
As part of the same agreement, the Group received in January 2022 the upfront fee of USD 20 million (CHF 18.6 million). Revenue related to the upfront payment is recognized over time in line with the progress made over the duration of the contractually agreed research plan.
During the three months ended March 31, 2024, the Group recognized as revenue an amount of TCHF 2,427 (three months ended March 31, 2023: TCHF 2,664) related to the upfront payment received in January 2022.

The Group has in recent years reported operating losses, with the exception of the year ended December 31, 2022, that resulted in a tax loss carry-forward in Switzerland of TCHF 144,483 as of December 31, 2023. No deferred tax assets have been recognized for these tax loss carry forwards because it is not probable that such loss carry forwards can be utilized in the foreseeable future. In addition, no deferred tax positions were recognized on other deductible temporary differences (e.g. pension liabilities under IAS 19) due to the significant tax loss carry forwards.

On May 23, 2023, an amended complaint was filed. The amended complaint alleged that the defendants violated federal securities laws by, among other things, making misrepresentations and omissions regarding its product candidate MP0310 and an associated licensing agreement. The amended complaint sought among others unspecified compensatory damages on behalf of persons and/or entities which purchased the Company's American Depositary Shares (ADSs) pursuant to certain offering documents issued in connection with the Company's initial public offering of ADSs. The Company and named individual defendants moved to dismiss the amended complaint on July 24, 2023. On February 5, 2024, the court dismissed the amended complaint without prejudice and gave plaintiff the opportunity to amend the complaint by February 26, 2024.
