Positive Points

• Fulcrum Therapeutics Inc (NASDAQ:FULC) completed enrollment in the 12 mg cohort of their Pioneer trial for sickle cell disease, with plans to share results in early Q3.
• The data monitoring committee recommended continuing the Pioneer study as planned, initiating the 20 mg cohort.
• The company reported a significant decrease in research and development expenses, attributed to the discontinuation of the losmapimod program and cost-sharing under the Sanofi collaboration.
• Fulcrum Therapeutics Inc (NASDAQ:FULC) ended the first quarter with $226.6 million in cash equivalents and marketable securities, sufficient to fund operations into at least 2027.
• The company plans to submit an IND for Diamond-Blackfan Anemia in the fourth quarter of this year, expanding their pipeline beyond sickle cell disease.

Negative Points

• Net loss for the first quarter of 2025 was $17.7 million, although this was an improvement from the previous year.
• The decrease in general administrative expenses was primarily due to a reduction in workforce, indicating potential operational challenges.
• The baseline fetal hemoglobin levels in the Pioneer trial were higher than anticipated, which could affect the interpretation of treatment efficacy.
• There is uncertainty regarding the FDA's stance on using fetal hemoglobin as a surrogate marker, which could impact future regulatory interactions.
• The company faces competition from other novel HBF inducers in the pipeline, such as those from BMS and GSK, which could affect market positioning.

Q & A Highlights

Q: Can you discuss the data expected from the 12 mg cohort of the Pioneer trial and the follow-up duration for the 16 patients enrolled? Will there be data on markers of hemolysis in addition to fetal hemoglobin data? A: Yes, we will provide hematological parameters, including blood counts and bilirubins, as indicators of hemolysis. We will have data for all 16 patients on the three-month treatment phase and a subset with a four-week follow-up. Not all 16 will have the full four-week follow-up due to the data cut timing.

Q: Does the observed dosing provide specific data on the number of doses patients are receiving in real-time? A: We capture adherence rates using an AI tool called AI Cure, which requires patients to register their dose intake. This method provides timely adherence data, showing greater than 90% adherence. We can determine if doses are taken at the same time daily, but we haven't decided if this will be presented in the upcoming data release.

Q: The baseline fetal hemoglobin (HBF) is higher than expected at 7%. Is this representative of the broader demographic, and how does Pociredir work in patients with higher baseline HBF? A: The sample size is small, but we believe it spans a range of baselines. We don't have evidence that baseline HBF determines response to Pociredir. Some patients with low baseline HBF showed robust induction. Higher baseline levels may result in lower absolute increases, but we need more data to comment further.

Q: What would be considered a successful outcome from the 12-week data? A: Any increase in fetal hemoglobin is beneficial, with a 1% increase potentially reducing VOCs by 4% to 8%. Clinically meaningful VOC reduction ranges from 25% to 50%. Single-digit increases in fetal hemoglobin can be significant, and reaching 25% could be transformative for patients.

Q: How do you view the impact of FDA shifts on endpoint selection and development timelines? Also, how do you plan to differentiate novel HBF inducers in your pipeline? A: We plan to engage with the FDA at the end of the 20 mg cohort to discuss future study plans. We are exploring various compounds that induce HBF and monitoring other inducers like BMS's and GSK's recent entries. Our focus is on finding alternative induction methods.
