Management Comments

• "With the advancement of our third program into clinical development, we continue to efficiently execute across our portfolio of only-in-class and first-in-class molecular glue degraders."
• "We have now dosed the initial single ascending dose (SAD) cohort in our Phase 1 study of MRT-8102, the only clinical-stage MGD that selectively degrades NEK7."
• "Based on the potency, selectivity, and durable pharmacodynamics seen in our preclinical studies, we believe MRT-8102 offers a highly differentiated approach to potentially address a wide range of inflammatory and cardio-immunology indications driven by the NLRP3 inflammasome, IL-1 and IL-6."
• "The execution of this program builds on the experience and success of our Phase 1 study for MRT-6160, our MGD directed against VAV1."
• "We continue, in collaboration with Novartis, to progress MRT-6160 towards a broad development program of multiple well-powered Phase 2 studies in immune-mediated diseases, building on our highly encouraging Phase 1 clinical data disclosed earlier this year."
• "In oncology, we continue to evaluate MRT-2359 in castration-resistant prostate cancer and are on track to report additional clinical data later this year."
• "We also eagerly anticipate a development candidate (DC) nomination this year and IND submission next year for one or both of our cell cycle programs directed at CCNE1 and CDK2, two well-validated tumor drivers poorly addressed by conventional approaches."
• "In parallel with the progress made with our clinical programs, we were proud to see fundamental results from our QuEEN discovery engine featured in Science, highlighting Monte Rosas leadership applying proprietary AI/ML techniques to the discovery of molecular glue degraders, dramatically expanding the addressable protein target space as well as the chemical space for MGDs to address these targets."
• "These advances underscore the broad potential applications of the platform and our ability to create long-term value through focused pipeline execution and strategic collaborations."
