17 Summary As of July 9, 2024 data cutoff • Data demonstrated vobra duo’s antitumor activity by ORR and PSA response rate • Anticipate having final TAMARACK median rPFS no later than early 2025 • Company believes it has better understanding of vobra duo’s overall safety and tolerability and is considering ways to further improve molecule’s safety as it awaits final median rPFS • Through dose reduction and increase in dosing interval, events of neutropenia, anemia, thrombocytopenia, pleural effusion and PPE syndrome improved compared to Phase 1 dose expansion in mCRPC; also, on average, TAMARACK study participants stayed on treatment longer than did those in Phase 1 • Company is considering exploring whether adverse events associated with prolonged exposure to vobra duo could be mitigated by strategies such as further increasing dosing intervals or utilizing loading doses Presented at ESMO 2024; Data Cut-off: July 9, 2024 September 16, 2024
