4. Bad News, Challenges, or Points of Concern

• Regulatory and Development Risks: The success of the IDE397 program hinges on GSK's decision to opt-in, which is contingent on the data package's completeness and the selected dose for expansion. There is uncertainty regarding the timing of GSK's decision and the potential need for maximum tolerated dose (MTD) data.
• Adverse Events: While the safety profile has been manageable, the presence of adverse events (AEs) and the need to monitor for serious adverse events (SAEs) remain a concern, particularly as the program progresses to higher dose cohorts.
