• 43% Objective Response Rate in frontline TP53m AML patients
• FDA granted Orphan Drug Designation for SL-172154 in AML treatment
• Addition to Russell 2000® and Russell 3000® Indexes
• Cash runway expected into 2026, beyond Phase 1 trial results

Negative

• Net loss increased to $21.5 million in Q2 2024 from $21.3 million in Q2 2023
• Cash and investments decreased to $105.3 million from $117.2 million year-over-year

• G&A expenses increased to $5.3 million from $4.7 million year-over-year

Financial Analyst

Shattuck Labs' Q2 2024 financial results reveal a mixed picture. The company's cash position of $105.3 million shows a 10.2% decrease from the same period last year, indicating ongoing cash burn. R&D expenses increased by 5.5% to $19.2 million, reflecting continued investment in clinical programs. G&A expenses also rose by 12.8% to $5.3 million.

The net loss of $21.5 million ($0.42 per share) is slightly higher than last year's $21.3 million, but the loss per share improved from $0.50, suggesting an increase in outstanding shares. The company's guidance of cash runway into 2026 is positive, providing a substantial buffer for ongoing clinical trials.

However, investors should note the lack of revenue and increasing expenses. The company's financial health hinges on the success of its clinical programs, particularly SL-172154. While the cash position appears adequate for near-term operations, continued losses may necessitate additional funding in the future.

Oncology Doctor

The interim data from Shattuck's Phase 1B trial of SL-172154 in combination with Azacitidine (AZA) shows promising results in difficult-to-treat patient populations. For HR-MDS patients, primarily with TP53 mutations, the 67% Objective Response Rate (ORR) and 58% complete remission rate are notably higher than historical data for AZA monotherapy, which typically shows ORRs around 30-40%.

In TP53m AML patients, the 43% ORR and 33% CR rate are also encouraging, given the poor prognosis associated with TP53 mutations. The fact that median overall survival had not been reached in either cohort at the data cut-off is a positive sign, though longer follow-up is needed to assess durability.

The manageable safety profile, with infusion-related reactions as the primary concern, is reassuring. However, it's important to see how these response rates translate to survival benefits in the ongoing randomized, controlled expansion cohort. The Orphan Drug Designation for AML treatment is a regulatory milestone that could expedite development and provide market exclusivity if approved.

Market Research Analyst

Shattuck Labs' focus on bi-functional fusion proteins positions it in a niche but growing segment of the biotechnology market. The company's lead candidate, SL-172154, is targeting high-need areas in oncology, particularly in hematological malignancies with poor prognoses.

The HR-MDS and TP53m AML markets are relatively small but have significant unmet needs. With an aging global population, the incidence of these diseases is likely to increase. If SL-172154 continues to show strong efficacy and safety data, it could potentially capture a substantial market share in these indications.

The company's pipeline diversity, including applications in solid tumors like ovarian cancer, provides multiple shots on goal. However, the competitive landscape is intensifying, with several companies developing novel therapies for these indications. Shattuck's success will depend on demonstrating superior efficacy or a better safety profile compared to emerging competitors.

Investor sentiment may be cautiously optimistic, as reflected in the company's recent addition to the Russell 2000® and Russell 3000® Indexes. This inclusion could increase visibility and potentially improve liquidity for the stock. However, as with many clinical-stage biotech companies, Shattuck's valuation will be highly sensitive to clinical trial outcomes and regulatory decisions in the coming years.

AUSTIN, TX and DURHAM, NC, Aug. 01, 2024 (GLOBE NEWSWIRE) -- 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.
