Zurich, Switzerland, August 26, 2021 - 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 unaudited financial results for the first half-year of 2021.

“Molecular Partners strongly expanded our global clinical presence and collaboration with Novartis in the first half of the year as the evolving COVID-19 pandemic continued to underscore the need for effective antiviral therapeutics. As a now dual-listed company in Switzerland and the United States, our expanded investor base enables us to accelerate our mission to deliver a new class of medicines to people living with cancer and infectious diseases,” said Patrick Amstutz, Ph.D., Chief Executive Officer of Molecular Partners. “To have entered two ongoing, late-stage trials of ensovibep further illustrates our rapid design and development capabilities. In addition to the COVID-19 program we are focused on expanding into new antiviral applications of the DARPin platform while moving towards a new phase for our immuno-oncology programs.”

Antiviral program: Rapid development of trispecific antiviral DARPin® candidate ensovibep in multiple international clinical trials

Molecular Partners advanced in 2021 with strong momentum for the Company’s lead antiviral candidate, ensovibep, which has progressed in the second quarter of 2021 into two ongoing, late-stage global clinical studies, EMPATHY and ACTIV-3, in collaboration with Novartis and the NIH, respectively. Thus far, ensovibep has provided positive Phase 1 data and continued to maintain potency in laboratory studies against all known COVID-19 variants of concern.

In March of 2021, Molecular Partners and its collaboration partner Novartis announced that the National Institutes of Health (NIH) selected ensovibep for inclusion in a global phase 3 randomized, controlled clinical trial as part of NIH’s Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV) program. The international master protocol ACTIV-3 is designed to evaluate the safety and efficacy of various therapies for the treatment of adults hospitalized with a COVID-19 diagnosis. A sub-study of ACTIV-3 evaluating ensovibep began enrolling hospitalized patients in June 2021 and is currently enrolling patients across seven countries. Topline data from this study are expected in 2022.

In May of 2021, Molecular Partners and its collaboration partner Novartis announced the start of the clinical trial EMPATHY, a global phase 2 - 3 study, to explore the use of ensovibep for the treatment of COVID-19 in patients who are in the early stages of infection, to prevent worsening symptoms and hospitalization. Molecular Partners’ collaboration partner Novartis is conducting the clinical trial for ensovibep, with Molecular Partners as sponsor. EMPATHY is currently enrolling patients across five countries. Topline interim data for the first 400 patients are expected towards the end of second half of 2021with complete data expected in 2022.  

In April of 2021, the first patient was dosed in a Phase 2a clinical trial of ensovibep in a single arm, open label study in the Netherlands that enrolled patients with mild symptomatic COVID-19, and is designed to evaluate the dynamics of viral clearance, pharmacokinetics and tolerability of ensovibep. This study enrolled a total of 12 patients in two dose cohorts, with data expected to be presented in a scientific conference in H2 2021. Initial results show a steady decline of viral loads in treated patients, validating the follow-up methods implemented in the Company’s ongoing late-stage trials, EMPATHY and ACTIV-3.

In March 2021, Molecular Partners reported positive initial Phase 1 results in healthy volunteers. Ensovibep, administered intravenously (I.V.), was seen to be safe and well tolerated, with no serious or severe adverse events reported. These preliminary results also confirmed extended exposure to ensovibep in serum, with a half-life of 2-3 weeks, as was expected from preclinical experiments. These data confirmed the systemic administration of ensovibep to be safe and well tolerated and supported the initiation of later stage trials. Following I.V. administration, ensovibep was also evaluated for safety and half-life when administered in bolus, and is presently being evaluated in subcutaneous (S.C.) administration in healthy subjects.

DARPin® molecules offer a differentiated approach to treating COVID-19 through a ‘cocktail in a molecule’ mechanism; a single molecule that can engage three domains of the SARS-CoV-2 virus simultaneously to inhibit viral entry into cells. This allows for a potentially broader efficacy and reduces the likelihood for the development of viral drug resistance which can result from selection pressure on any single molecular target. In addition, DARPin® candidates are produced through rapid, high-yield microbial fermentation for potential speed and logistical advantages over mammalian cell production employed for antibodies.

Based on the success seen to-date of ensovibep’s unique approach to neutralizing the virus, Molecular Partners is also evaluating the next generation of opportunities to develop antivirals against other infectious diseases with global unmet need.

Immuno-oncology programs: Clinical work for AMG 506 / MP0310 (FAP x 4-1BB) ongoing; new supportive data published across acute myeloid leukemia and MP0317 (FAP x CD40) programs as well as novel technology platforms

Following the positive initial results of MP0310, clinical work advanced into weekly administration of MP0310 in the Phase 1 study, to identify a dosing regimen to obtain sustained 4-1bb activation. Molecular Partners expects to obtain data from this trial within 2021, allowing for its partner, Amgen, to evaluate potential future development of MP0310 in combination with Amgen’s oncology assets, including BiTE® molecules.

In April of 2021, Molecular Partners presented four posters highlighting research across its immuno-oncology programs at the American Association for Cancer Research (AACR) virtual Annual Meeting. Molecular Partners’ novel multi-specific DARPin® candidates are designed to activate the immune system to fight cancer while reducing damage to healthy cells. These candidates use multiple novel DARPin® technologies potentially applicable against a wide range of tumor types. The preclinical data shared include first results from the Company’s acute myeloid leukemia (AML) CD3 T-cell engager program, initial results from the CD3 prodrug program, and new data from the MP0317 and peptide-MHC programs.

With respect to MP0317, a multi-specific DARPin® product candidate targeting both FAP and CD40 to enable tumor-localized immune activation, new preclinical data showed activation of B-cells and myeloid cells in ex vivo human tumor samples. This demonstrated that physiological presence of FAP, expressed in the connective tissue of a broad range of solid tumors, is mandatory and sufficient for MP0317 to induce immune activation. Furthermore, the data presented at AACR shows that MP0317 led to a range of pro-inflammatory activities, including macrophage repolarization and reversion of T‑cell suppression only in the presence of FAP. In both assays the killing effect was comparable to that achieved by an anti-CD40 antibody. The Company believes these data support MP0317’s potential to deliver tumor-localized CD40-mediated immune cell activation while avoiding systemic toxicity seen with other agents. MP0317 is anticipated to begin clinical trials in the second half of 2021.

In preclinical studies, the Company’s AML research candidates demonstrated substantial activity against different populations of AML cells in vitro and ex vivo, without significant damage to healthy cells. The candidate is further designed to bind with increased avidity as the number of relevant antigens presented increases, further strengthening its preference for tumor cells. The candidate is a single molecule designed to target three different cancer antigens simultaneously (CD70, CD33, and CD123). This multi-specific DARPin® T-cell engager candidate is designed to deliver a highly potent and specific anti-tumor response to AML cells, with a reduced effect on healthy normal cells, and with the potential to counteract target escape mechanisms expected due to tumor heterogeneity. The AML DARPin candidate demonstrated potent induction of T-cell mediated cytotoxicity against AML cell lines and primary AML calls. In an ex vivo assay using fresh blood from healthy donors, the candidate induced profoundly less inflammatory cytokine production and reduction in platelet counts than T-cell engager candidates in development by other parties. Molecular Partners believes this candidate shows a unique avidity-driven ability to kill a broader population of AML cells while decreasing the risk of toxicity.

Molecular Partners’ T-cell engager programs also include a novel prodrug DARPin® technology for tumor-localized release of immune stimulation, through incorporation of a protease-cleavable blocker DARPin® molecule. As CD3-binding T-cell engagers are highly potent and can lead to systemic toxicities, Molecular Partners has developed a DARPin® domain designed to mask the CD3 engager from interacting with T cells, systemically or outside of the tumor, thus reducing toxicity by limiting immune activation to the tumor microenvironment. Molecular Partners’ prodrug research candidate, CD3-PDD, has demonstrated in vitro and in vivo proof-of-concept, being shown to be unable to bind and recruit T-cells in its non-cleaved state in circulation while delivering an anti-tumor effect.

Finally, new data were presented supporting Molecular Partners’ peptide-MHC targeting program, which focuses on developing the capability to target cell surface protein complexes indicating disease through display of intracellular peptides. At AACR, the Company presented preclinical results demonstrating rapid and reliable generation of DARPin® proteins against a peptide-MHC complex (pMHC). These DARPin® proteins were then formatted into bispecific T-cell engagers, and engineered to enable potent and specific activation of T cells. Further, the results showed that a pMHC-targeting DARPin® candidate was able to achieve systemic half-life extension.

Ophthalmology
In August, the Company was updated by its collaboration partner, AbbVie Inc. of its termination of the license and collaboration agreement for the investigational drug abicipar pegol for the treatment of nAMD and DME. As such, Molecular Partners will regain the development and commercial rights of abicipar on a worldwide basis.

Financial Highlights: Nasdaq offering extends cash runway into H2 2023
Molecular Partners remains solidly funded to capture upcoming value inflection points. In June 2021, the Company successfully completed an initial public offering of American Depositary Shares on the NASDAQ exchange, raising $63.8 million (CHF 58.8 million) in gross proceeds. With the U.S. listing, Molecular Partners has broadened its access to capital from the global investment community to support its programs and growing pipeline. In the first six months of 2021, Molecular Partners recognized total revenues and other income of CHF 4.4 million (H1 2020: CHF 7.5 million) and incurred total operating expenses of CHF 39.2 million (H1 2020: CHF 30.6 million). This led to an operating loss of CHF 34.8 million for the first six months in 2021 (H1 2020: Operating loss of CHF 23.1 million) and a net loss of CHF 33.6 million for H1 2021 (H1 2020: Net loss of CHF 24.7 million).

The net cash outflow from operating activities during the first six months in 2021 was CHF 52.5 million (2020: net cash outflow of CHF 27.9 million). Including time deposits, the cash and cash equivalents position increased by CHF 0.6 million vs. year-end 2020 to CHF 174.3 million as of June 30, 2021 (December 31, 2020: CHF 173.7 million).

Total shareholders’ equity stood at CHF 134.6 million as of June 30, 2021, an increase of CHF 27.4 million (December 31, 2020: CHF 107.2 million). As of June 30, 2021, the Company employed 158 FTEs (full time equivalents), up 15 year-on-year. About 80% of the employees are employed in R&D-related functions.

KEY FIGURES AS OF JUNE 30, 2021

 

BUSINESS OUTLOOK AND PRIORITIES
In the second half of 2021, Molecular Partners remains focused on the rapid clinical development of ensovibep across two major global studies as well as a further bridging study to evaluate the option of subcutaneous/intramuscular administration. Topline interim data for the first 400 patients from the ongoing EMPATHY trial are expected in the second half of 2021 with full interim data expected in early 2022. Molecular Partners is committed to advancing other antiviral programs and is currently evaluating several potential targets with global unmet need. The Company expects to announce additional antiviral programs in the second half of 2021. In immuno-oncology, Molecular Partners expects to provide results from the MP0310 trial to Amgen, to inform their decision regarding future development of the program. Further, the Company intends to begin clinical studies of MP0317 in the second half of 2021 and expects to present additional research data from its trispecific CD3 T-cell engager for the treatment of AML. Molecular Partners is now working with AbbVie for the receipt of data and materials related to the abicipar program. The Company has formed a special committee to evaluate the program and determine appropriate next steps regarding abicipar.

FINANCIAL OUTLOOK 2021
For the full year 2021, at constant exchange rates, the company continues to expect total expenses of CHF 65-75 million, of which around CHF 7 million will be non-cash effective costs.
In terms of cash outflow the company expects a gross cash utilization of CHF 85-95 million for FY2021, which includes a total of CHF 20 million payable to Novartis for the manufacturing of commercial supply (of which CHF 10.5 million occurred during H1 2021). This cash flow guidance does not include any potential receipts from R&D partnerships.
