Shattuck Labs Reports Second Quarter 2024 Financial Results and Recent Business Highlights
–Announced updated positive interim data from the Phase 1B dose-expansion clinical trial of SL-172154 in combination with Azacitidine (AZA) in frontline Higher-Risk Myelodysplastic Syndromes (HR-MDS) and TP53 mutant (TP53m) Acute Myeloid Leukemia (AML) patients at the European Society of Hematology (EHA) 2024 Annual Meeting–
–Enrollment ongoing in the randomized, controlled Phase 1B dose-expansion cohort in frontline HR-MDS patients –
–Announced Orphan Drug Designation (ODD) granted by the U.S. Food and Drug Administration (FDA) for SL-172154 for the treatment of AML–
AUSTIN, TX and DURHAM, NC, August 1, 2024 – Shattuck Labs, Inc. (Shattuck) (Nasdaq: STTK), a clinical-stage biotechnology company pioneering the development of bi-functional fusion proteins as a new class of biologic medicine for the treatment of patients with cancer and autoimmune disease, today reported financial results for the quarter ended June 30, 2024 and provided recent business highlights.
“Our data presentation at EHA last quarter included complete remission rates for both HR-MDS and TP53m AML patients treated with SL-172154 in combination with AZA that exceeded the expected complete remission rates for AZA alone. It is encouraging to see in our EHA presentation that our complete remission rate improved as the number of patients in each cohort increased, since our initial data presented at ASH in December of 2023. The next milestone for this program is to see how these response rates translate to an overall survival benefit, and those data will mature over the second half of this year,” said Taylor Schreiber, M.D., Ph.D., Chief Executive Officer of Shattuck. “In parallel, we are pleased that enrollment has begun so swiftly in our randomized, controlled expansion cohort in frontline HR-MDS patients. We look forward to sharing clinical updates from these trials in the months ahead.”
Second Quarter 2024 Business Highlights and Other Recent Developments
SL-172154 (SIRPα-Fc-CD40L)
Phase 1B Trial of SL-172154 in Frontline HR-MDS and TP53m AML
HR-MDS
•Announced updated interim data from the Phase 1B dose expansion clinical trial of SL-172154 in combination with AZA in frontline HR-MDS and TP53m AML patients. These data were featured in a poster presentation during the EHA 2024 Congress.
◦Observed 67% Objective Response Rate (ORR) in frontline HR-MDS patients, primarily with TP53 mutations, and an initial complete remission (CR)/marrow complete remission rate of 58%. As of the data cut-off date on April 23, 2024, median overall survival had not yet been reached.
◦SL-172154 demonstrated a manageable interim safety profile in combination with AZA, with infusion related reactions (IRRs) as the most common drug related adverse event.
•Initiated enrollment of the Part D cohort, a randomized, controlled Phase 1B dose-expansion cohort in frontline HR-MDS patients. Approximately 60 patients will be randomized in a 1:1:1 ratio to receive SL-172154 at 3mg/kg in combination with AZA, SL-172154 at 1mg/kg in combination with AZA, or AZA as monotherapy.
TP53m AML
•Observed 43% ORR in frontline TP53m AML patients and 33% CR/complete remission rate with incomplete hematologic recovery. As of the data cut-off date of June 4, 2024, the median overall survival


had not yet been reached. SL-172154 demonstrated a manageable interim safety profile in combination with AZA.
•In June 2024, the U.S. FDA granted ODD to SL-172154 for the treatment of AML.
Phase 1B Trial of SL-172154 in Platinum-Resistant Ovarian Cancer (PROC)
•Reported data from the Phase 1B clinical trial of SL-172154 in PROC patients, demonstrating an acceptable safety profile in combination with pegylated liposomal doxorubicin (PLD) or mirvetuximab soravtansine (Elahere). IRRs were the most common treatment emergent AE as of the data cutoff.
◦As of April 23, 2024, four of 21 (19%) treated patients in the Phase 1B study of SL-172154 in combination with PLD achieved partial responses. Two additional patients with stable disease showed maximum tumor reductions of 17% and 27%.
◦Completed enrollment for the cohort combining SL-172154 with Elahere. As of the April 23, 2024 data cutoff, ORR benefit beyond Elahere alone was not observed.
◦Shattuck continues to follow patients for progression free survival and overall survival and, should such results mature favorably in either PROC cohort, will evaluate further development in PROC at that time.
Corporate Updates
•On July 1, 2024, Shattuck announced its addition to the Russell 2000® and Russell 3000® Indexes at the conclusion of the 2024 Russell U.S. Indexes annual reconstitution.
Upcoming Events
•Shattuck plans to attend the following investor conferences. Details will be included on the Events & Presentations section of the Company’s website.
