"Following a significant capital inflow in January, resulting from Novartis exercising its right to in-license global rights to ensovibep, we are leveraging our strong cash position to follow our strategy; to prioritize candidates where DARPins have an innate advantage over other approaches. Programs like ensovibep, the breakthrough design of MP0533 and our new research in radioligand therapies, showcase the success of our evolved strategy, which emphasizes highly differentiated molecules that can rapidly demonstrate clear activity and benefit for patients," said Patrick Amstutz, Molecular Partners’ CEO. "We continue to support Novartis on next steps for ensovibep’s global strategy as we advance our internal portfolio, building on the strong clinical performance our DARPins candidates have continually demonstrated."
Research & development highlights:
Ensovibep COVID-19 antiviral program: Positive Phase 2 results, Option exercised by Novartis
Part A of the EMPATHY global clinical trial met its primary endpoint with a statistically significant reduction in viral load over eight days in the ensovibep arms compared to placebo
Secondary EMPATHY endpoint of hospitalization and/or emergency room (ER) visits related to COVID-19, or death showed an overall 78% reduction in relative risk of events across all ensovibep arms compared to placebo
In April, the results of the EMPATHY Part A study were presented as a late breaker at the 2022 European Congress of Clinical Microbiology and Infectious Diseases (ECCMID)
Novartis exercised the option to license all rights to ensovibep, triggering a CHF 150 million payment to Molecular Partners
Novartis requested Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA) for ensovibep. As previously reported by Novartis, the EUA remains under review, and the FDA has indicated that Phase 3 data will be required prior to authorization. Novartis is currently engaged in developing a Phase 3 protocol for alignment with the FDA’s recommendations
MP0310 (FAP x 4-1BB)
Amgen returned global rights for MP0310 following a strategic pipeline review. The ongoing Phase 1 study is expected to continue as planned, with data expected later in 2022 that will inform further business development activity
MP0317 (FAP x CD40):
The Phase 1 open-label dose escalation study, initiated in Q4 2021, continues in patients with solid tumors known to express FAP. Initial data from this study is expected in the second half of 2022
In March 2022, preclinical data were published in the research journal Cancer Immunology Research1 supporting MP0317’s potential to deliver tumor-localized immune activation while avoiding systemic toxicity seen with other CD40-targeting agents
MP0533 (CD33 x CD70 x CD123 x CD3)
Following continued promising preclinical data supporting the unique design and mechanism of this candidate, a lead molecule was selected and named MP0533. It is expected to enter clinical development in 2022
New in vivo data from the MP0533 program will be presented at the European Hematology Association (EHA) (Free EHA Whitepaper) Congress (EHA2022) which will be held in Vienna, Austria from June 9 to 12
Q1 2022 operational and financial highlights:
Strong financial position with CHF 296.2 million in cash (including short term deposits) as of March 31, 2022
Revenue of CHF 172.8 million primarily due to payment received from Novartis upon exercise of option to in-license global rights to ensovibep
Net cash from operating activities of CHF 163.6 million in Q1 2022
Operating profit of CHF 152.6 million and net profit of CHF 153.1 million in Q1 2022
Company expected to be funded into 2026, excluding any potential payments from R&D partnerships

Ensovibep for COVID-19: In partnership with Novartis
Ensovibep is a first-in-class, multi-specific pan-variant DARPin therapeutic candidate, designed to bind three different epitopes on the receptor-binding domain (RBD) of the SARS-CoV-2 spike protein simultaneously.
Part A of the EMPATHY clinical trial – a randomized, placebo-controlled study which enrolled 407 symptomatic patients infected with SARS-CoV-2 – met its primary endpoint with a statistically significant reduction in viral load over eight days in the ensovibep arms compared to placebo. The secondary endpoint of hospitalization and/or emergency room (ER) visits related to COVID-19, or death showed an overall 78% reduction in relative risk of events across all ensovibep arms compared to placebo.
Pursuant to the Option and Equity Rights Agreement executed in October 2020 with Novartis and following positive Phase 2 (Part A) results, Novartis exercised its option for ensovibep in January 2022, triggering a milestone payment of CHF 150 million to Molecular Partners. Novartis is now responsible for further development, manufacturing, distribution and commercialization activities.
Novartis requested Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA) for ensovibep. As previously reported by Novartis, the application of the EUA remains under review and additional clinical data will be required to be authorized. While the current Omicron wave of SARS-Cov-2, and the lower incidence of hospitalization associated with it, has made clinical trials challenging to execute in this evolving environment, Novartis is continuing to supply additional documentation and data to the FDA in regards to the EUA review. The FDA has indicated that additional Phase 3 clinical data will be required to support EUA; Novartis is currently engaged in developing a Phase 3 study protocol in alignment with the FDA’s recommendations.
If approved or authorized by relevant regulatory authorities, ensovibep would be the first approved multi-specific antiviral candidate for the treatment of COVID-19 and the first DARPin therapy approved or authorized by a regulatory agency. Based on the strong clinical performance of ensovibep, the Company is assessing further viral disease areas where DARPins can offer advantages over existing antivirals or where no effective treatments exist.
Oncology: Phase 1 trial of MP0317; Phase 1 trial of MP0310; Progress of AML candidate MP0533; Development of a DARPin-based radioligand program
The ongoing Phase 1 trial of MP0317 is expected to enroll up to 30 patients across six dosing cohorts and up to 15 patients are then expected to be enrolled in a dose expansion cohort. In addition to evaluating monotherapy dynamics, the study plans to gather a wide variety of biomarker data to support the establishment of combination therapies with MP0317 in specific indications. MP0317 targets both the fibroblast activation protein (FAP) and the immunostimulatory protein CD40. MP0317 is designed to enable tumor-localized immune activation and fewer side effects compared to other CD40-targeting agents.
MP0310 is also designed to deliver tumor-localized immune activation and activates the immunostimulatory 4-1BB protein. A Phase 1 study of this candidate as a treatment for solid tumors is ongoing, with a full dataset expected later in 2022. Following Amgen’s strategic pipeline review and return of global rights to MP0310, the Phase 1 dataset will inform further business development activity.
MP0533, Molecular Partners’ novel acute myeloid leukemia (AML) candidate, is a DARPin designed to engage CD3 on T-cells while binding up to three tumor-associated antigens (CD33, CD70 and CD123) on AML cells. Preclinical studies have shown the binding strength of MP0533 increasing significantly with the number of tumor-associated antigens present. This ‘avidity-dependent’ mechanism, enabled by the DARPin platform, leads to preferential targeting of AML cells which, unlike healthy cells, generally express two or more of these antigens. Once bound, the AML cells are marked for termination by nearby T-cells activated by MP0533. Clinical development is expected to begin in 2022.
Molecular Partners is also collaborating with Novartis to develop, manufacture and commercialize DARPin-conjugated radioligand therapies (DARPin-RLTs). The collaboration combines DARPins’ unique properties, including small size and very high affinity and specificity, with the RLT capabilities and expertise of Novartis. DARPin-RLTs have the potential to deliver molecule-targeted radiation deeply into the tumor thereby harnessing the power of radioactive atoms for tumor-killing. Under the terms of the agreement, Molecular Partners will collaborate with Novartis to discover DARPin-RLTs that target specific tumor-associated antigens. Both parties will collaborate on the discovery and optimization of the therapeutic candidates for further development.
