• MRT-6160 has shown promising preclinical results in multiple models of autoimmune disease.
• The company is on track to initiate a Phase 1 study for MRT-6160 this summer.
• The company has a strategic collaboration with Roche to discover and develop MGDs.

Risks

• The company's forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially.
• The company has not independently verified third-party data and makes no representations as to its accuracy.
• There is no guarantee that the future results, performance, or events described in the forward-looking statements will be achieved or occur.

Future Outlook

The company anticipates determining the recommended Phase 2 dose for MRT-2359 in the second half of 2024 and initiating a Phase 1 study for MRT-6160 this summer, with initial clinical data expected in Q1 2025. They also plan to initiate proof-of-concept studies in autoimmune/inflammatory diseases.

Management Comments

• We are pleased with the progress of our two lead programs, said Markus Warmuth, M.D., Chief Executive Officer of Monte Rosa Therapeutics.
• We continue to successfully recruit and advance our ongoing MRT-2359 Phase 1/2 study.
• We are encouraged by our initial safety and pharmacodynamic assessment of the 0.5 mg dose using the 21 days on, 7 days off regimen and, as such, we consider the 0.5mg dose with the 21 days on, 7 days off regimen a potential recommended Phase 2 dose.
• Moreover, today we are excited to announce the submission of our Investigational New Drug (IND) application to the U.S Food and Drug Administration (FDA) for MRT-6160.

Industry Context

This announcement highlights the growing interest in molecular glue degraders as a therapeutic modality, particularly in oncology and autoimmune diseases. The company's progress in both areas positions them as a key player in this emerging field.

Comparison to Industry Standards

• The development of MRT-2359 for MYC-driven tumors is in line with the industry's focus on targeting difficult-to-drug oncogenes.
• The IND submission for MRT-6160 as a rationally designed MGD for a non-oncology indication is a novel approach, differentiating Monte Rosa from other companies primarily focused on oncology.
• The company's strategic collaboration with Roche is a significant endorsement of their technology and approach, similar to other biotech companies partnering with larger pharmaceutical firms.

Stakeholder Impact

• Shareholders will likely view the progress updates positively, potentially leading to increased investor confidence.
• Employees may be motivated by the positive developments in the company's clinical programs.
• Patients with MYC-driven solid tumors and autoimmune diseases may benefit from the potential new therapies.
• The company's collaboration with Roche could lead to further opportunities for growth and development.

Next Steps

• The company will determine the definitive recommended Phase 2 dose for MRT-2359 in the second half of 2024.
• The company will initiate a Phase 1 SAD/MAD study for MRT-6160 this summer.
• The company will share initial clinical data for MRT-6160 in Q1 2025.
• The company will initiate proof-of-concept studies in autoimmune/inflammatory diseases.
