Imago BioSciences Presents Positive Data from Ongoing Phase 2 Study of Bomedemstat in Advanced Myelofibrosis at ASH 2022

- As of the data cutoff of 18 October 2022, bomedemstat demonstrated spleen volume reduction in 66% (33/50) of patients and reduction in total symptom score in 65% (17/26) of patients at 24 weeks -

- No patients in this Phase 2 study of bomedemstat in advanced myelofibrosis have progressed to acute myeloid leukemia while on treatment -

- The Phase 2 study of bomedemstat in advanced myelofibrosis is fully enrolled, with an investigator-sponsored Phase 2 combination study of bomedemstat and ruxolitinib in myelofibrosis currently screening patients -

Redwood City, Calif. – December 12, 2022 – Imago BioSciences, Inc. (“Imago”) (Nasdaq: IMGO), a clinical-stage biopharmaceutical company discovering and developing new medicines for the treatment of myeloproliferative neoplasms (MPNs) and other bone marrow diseases, today presented positive data from its ongoing global Phase 2 clinical study evaluating bomedemstat in patients with advanced myelofibrosis (MF).

The data were presented in a poster presentation session during the 64^th American Society of Hematology Annual Meeting and Exposition (ASH) taking place 10-13 December 2022. A Phase 2 data set with a cut-off date of 29 April 2022 was previously presented at the 30^th European Hematology Association Annual Meeting and congress (EHA) in June 2022.

Updated Highlights (available data as of 18 October 2022)

• Of evaluable patients at 24 weeks:

• 65% (17/26) showed a decrease in Total Symptom Score (TSS).

• 19% (5/26) showed a ≥ 50% decrease in TSS.

• 66% (33/50) showed spleen volume reductions from baseline.

• 28% (14/50) showed a ≥ 20% spleen volume reduction.

• The majority of patients had a decrease in mutant allele frequencies (MAF) including driver mutations (e.g., JAK2) and high molecular risk (HMR) mutations (e.g., ASXL1).

• 90% (37/41) of transfusion-independent patients had stable (19/41) or improved (18/41) hemoglobin at Week 12.

• 85% (50/59) of patients had an improved (19/59) or stable (31/59) bone marrow fibrosis score post-baseline.

• No new mutations or transformations to acute myeloid leukemia (AML) while on treatment, even in patients with a high-risk of progression.

“Bomedemstat continues to demonstrate its potential as a monotherapy for patients suffering from advanced myelofibrosis, highlighted by the data presented at ASH showing improvements in patient symptom scores, spleen volumes, fibrosis, and anemia,” said Hugh Young Rienhoff, Jr., M.D., Chief Executive Officer of Imago BioSciences. “I am also delighted we continue to see the majority of patients experience a decrease in mutant allele frequencies and no progression to AML, even in patients with ASXL1 mutations known to confer a high-risk of transformation. We are further exploring the use of bomedemstat in myelofibrosis in an investigator-sponsored Phase 2 combination study with ruxolitinib; patients are currently being screened.”

Safety and Tolerability

• Bomedemstat was generally safe and well-tolerated in patients with myelofibrosis.

• The most common non-hematologic adverse event (AE) related to bomedemstat was dysgeusia (altered taste), which occurred in 33% (30/90) of patients and led to discontinuation of the study in 1 patient.

• There were 44 patients who reported a total of 86 serious adverse events (SAEs), 16% of which were deemed drug-related by the investigator.

About Imago BioSciences

Imago BioSciences is a clinical-stage biopharmaceutical company discovering and developing novel small molecule product candidates that target lysine-specific demethylase 1 (LSD1), an enzyme that plays a central role in the production of blood cells in the bone marrow. Imago is focused on improving the quality and length of life for patients with cancer and bone marrow diseases. Bomedemstat, an orally available, small molecule inhibitor of LSD1, is the lead product candidate discovered by Imago for the treatment of certain myeloproliferative neoplasms (MPNs), a family of related, chronic cancers of the bone marrow. Imago is evaluating Bomedemstat as a potentially disease-modifying therapy in two Phase 2 clinical trials for the treatment of essential thrombocythemia (NCT04254978) and myelofibrosis (NCT03136185). Bomedemstat has U.S. FDA Orphan Drug and Fast Track Designation for the treatment of ET and MF, European Medicines Agency (EMA) Orphan Designation for the treatment of ET and MF, and PRIority MEdicines (PRIME) Designation by the EMA for the treatment of MF. Imago is based in Redwood City, California.
