"Shattuck made the difficult but appropriate decision to terminate our SL-172154 program in 2024, and rapidly transitioned to our potential first-in-class DR3 blocking antibody, SL-325," said Taylor Schreiber, M.D., Ph.D., Chief Executive Officer of Shattuck. "In February, we presented preclinical results from our IND-enabling GLP toxicology study for SL-325 at ECCO, demonstrating differentiation from TL1A blocking monoclonal antibodies, along with a favorable safety profile, full receptor occupancy, and lack of DR3 agonism. Our encouraging preclinical data underscore SL-325’s potential for DR3 blockade to provide potentially best-in-class clinical remission rates for IBD patients. We are on track for an IND filing in the third quarter of this year and are excited to begin generating data with the first-ever DR3 blocking antibody to enter clinical trials. Shattuck remains well-positioned to fund operations and clinical development of SL-325 into 2027."

DR3 Program Development in 2025

•Shattuck’s lead product candidate, SL-325, is a potentially first-in-class DR3 antagonist antibody. SL-325 is a DR3 blocking antibody for the treatment of IBD and other inflammatory and immune-mediated diseases.
◦IND filing expected in the third quarter of 2025.
◦Phase 1 clinical trial will evaluate safety, tolerability, and pharmacokinetics, and determine the recommended Phase 2 dose and dosing schedule of SL-325, with complete enrollment expected in the second quarter of 2026.
•Shattuck continues to develop multiple preclinical DR3-based bispecific antibodies, which are designed to inhibit both the DR3/TL1A axis and another biologically relevant target for the treatment of patients with IBD. Shattuck plans to nominate a lead bispecific candidate from its preclinical pipeline in 2025.

Fourth Quarter 2024 Business Highlights and Other Recent Developments

DR3 Program Development
•Shattuck Labs participated in an oral presentation at ECCO in February 2025.
◦Preclinical studies of SL-325 in NHP demonstrated a favorable safety profile with no infusion-related reactions observed, no changes in clinical pathology parameters, gross pathology, or histopathology analysis, and a No Observed Adverse Effect Level determined to be 100mg/kg, the top administered dose;
◦Full receptor occupancy at 1 mg/kg or greater, durable for >28 days, no Treg expansion or activation of CD3 T cells observed; and •Differentiation from TL1A blocking monoclonal antibodies may yield a distinct profile for bispecific antibody development. Notably, by targeting DR3, immune complex formation and stabilization of TL1A is not expected with SL-325, which may improve the immunogenicity profile as compared to TL1A targeting agents and allow for the development of DR3-based bispecific antibodies. Durable blockade of constitutively expressed DR3 may translate to higher complete remission rates.
•Shattuck Labs presented a poster at the 2025 Crohn’s & Colitis Foundation Congress in February.
◦Data from in vitro preclinical development and characterization of SL-325 were presented.
◦SL-325 is a fully Fc-silenced humanized immunoglobulin G monoclonal antibody that demonstrated high affinity binding to human DR3 and potent antagonistic properties with no evidence of residual agonism.
Upcoming Events
•Shattuck plans to attend the following investor conference. Details will be included on the Events & Presentations section of the Company’s website.
◦24th Annual Needham Virtual Healthcare Conference, April 7–10, 2025. Taylor Schreiber, M.D., Ph.D., CEO of Shattuck Labs, will participate in a presentation on April 9, 2025.

About SL-325
SL-325 is a potential first-in-class Death Receptor 3 (DR3) blocking antibody designed to achieve a complete and durable blockade of the clinically validated DR3/TL1A pathway. Shattuck’s preclinical studies demonstrate high affinity binding and superior activity over TL1A antibodies, and offer a data-driven rationale for targeting the TNF receptor, DR3, versus its ligand, TL1A. SL-325 has completed a GLP toxicology study in non-human primates, with an IND filing expected in the third quarter of 2025.

On March 27, 2025 BeyondSpring Inc. (NASDAQ: BYSI) ("BeyondSpring" or the "Company"), a global clinical-stage biopharmaceutical company developing innovative cancer therapies, reported its financial results for the year ended December 31, 2024, and provided a business update on key clinical and corporate developments (Press release, BeyondSpring Pharmaceuticals, MAR 27, 2025, View Source;utm_medium=rss&utm_campaign=beyondspring-reports-2024-year-end-financial-results-and-highlights-key-clinical-strategic-milestones [SID1234651519]).

"2024 was a pivotal year for BeyondSpring, with significant clinical progress for our first-in-class agent Plinabulin and strategic advancements for SEED Therapeutics (SEED), which BeyondSpring co-founded and owns an equity stake in. We believe these developments create value benefiting all stakeholders," said Dr. Lan Huang, Co-Founder, Chairman, and CEO of BeyondSpring.

"Plinabulin demonstrated a statistically significant survival benefit in patients with second- and third-line non-small cell lung cancer (NSCLC) (EGFR wild-type), a setting where no new therapies have been approved in over a decade. This Phase 3 data, now published in The Lancet Respiratory Medicine, strengthens our regulatory strategy as we prepare for submission to the Chinese National Medical Products Administration (NMPA) and potentially regulatory authorities in other jurisdictions."

"BeyondSpring is also advancing Plinabulin’s potential as a next-generation immuno-oncology agent, with its potent effect in dendritic cell maturation. An ongoing Phase 2 study showed that Plinabulin, in combination with a PD-1 inhibitor and docetaxel, produced promising efficacy in patients with metastatic NSCLC who had progressed on prior PD-1/PD-L1 inhibitors with good tolerability. While PD-1 and PD-L1 antibody annual sales have exceeded $50 billion, with most sales coming from lung cancer, 60% of patients across multiple cancer indications develop acquired resistance to checkpoint inhibitors, which we believe represents a significant opportunity for Plinabulin to impact the treatment landscape and create substantial value."

"SEED also made significant progress in 2024, securing a strategic research collaboration with Eisai Co., Ltd. ("Eisai"), a second global pharma partnership in addition to the Eli Lilly and Company ("Lilly") partnership. Under this collaboration, SEED will be eligible to receive upfront payments and potential preclinical, clinical, regulatory and sales milestone payments of up to $1.5 billion, plus tiered royalties on net sales. In parallel, SEED is advancing its internal lead oncology asset, RBM39 degrader, toward clinical development. SEED’s recognition in two Nature review papers as a leader in targeted protein degradation (TPD), along with recent granting of Rare Pediatric Disease and Orphan Drug Designations by the FDA for its RBM39 degrader ST-01156, further underscore its unique platform and reinforce its leadership in this emerging field."

"With strongly anchored pipelines, key global partnerships and deliberate plans to navigate regulatory pathways, we believe BeyondSpring and SEED are well-positioned to drive transformative advancements in oncology and TPD in 2025," Dr. Lan Huang concluded.

Fourth Quarter and Full Year 2024 and Recent Corporate Highlights

TYRA-300

•
Advanced Clinical Evaluation of TYRA-300 into Three Phase 2 Studies. During 2024, TYRA progressed TYRA-300, an oral, investigational FGFR3-selective inhibitor, for the treatment of IR NMIBC, mUC and ACH, and achieved the following milestones:
o
Cleared Phase 2 NMIBC IND with US FDA – SURF302. TYRA expanded the clinical development of TYRA-300 into NMIBC to address the unmet needs in this cancer population for an efficacious, orally available therapy. SURF302 is an open-label Phase 2 clinical study evaluating the efficacy and safety of TYRA-300 in participants with FGFR3-altered low-grade, IR NMIBC. The study will enroll up to 90 participants at multiple sites primarily in the United States. Participants will be randomized initially to treatment with TYRA-300 at 50 mg once-daily (QD) (Cohort 1) or treatment with TYRA-300 at 60 mg QD (Cohort 2). Following a review of efficacy and safety, an additional dosing cohort may be evaluated. The primary endpoint is complete response (CR) rate at three months. Secondary endpoints include time to recurrence, the median duration of response, recurrence free survival (RFS), progression free survival (PFS), safety and tolerability.
o
Cleared Phase 2 ACH IND with US FDA – BEACH301. The study is a Phase 2, multicenter, open-label, dose-escalation/dose-expansion study evaluating TYRA-300 in children ages 3 to 10 with achondroplasia with open growth plates. The study will enroll children who are treatment-naïve (Cohort 1) and those who have received prior growth-accelerating therapy (Cohort 2) at multiple sites across the globe. Each of these cohorts is expected to enroll up to 10 participants per dose level (0.125, 0.25, 0.375, 0.50 mg/kg) for up to 12 months. The study will initially enroll a safety sentinel cohort of up to 3 treatment-naïve participants per dose level in children ages 5 to 10.

o
Reported Interim Clinical Proof-of-Concept Results in mUC Patients – SURF301. TYRA-300 demonstrated encouraging preliminary anti-tumor activity in a heavily pre-treated population: at ≥ 90 mg QD, 6 out of 11 (54.5%) patients with FGFR3+ mUC achieved a confirmed partial response (PR), with 100% disease control rate and sustained duration of activity; positive safety results were reported across all QD doses, with infrequent FGFR2/FGFR1-associated toxicities (data cutoff of August 15, 2024). TYRA-300 is being evaluated in Part B of SURF301 (NCT05544552) at potentially therapeutic QD doses in preparation for potential future Phase 2 studies.

TYRA-200

•
Advanced Phase 1 SURF201 Study. TYRA-200 is an FGFR1/2/3 inhibitor with potency against activating FGFR2 gene alterations and resistance mutations. SURF201 (Study in PrevioUsly treated and Resistant FGFR2+ Cholangiocarcinoma and Other Advanced Solid Tumors) (NCT06160752) is a multi-center, open label study designed to evaluate the safety, tolerability, and pharmacokinetics of TYRA-200 and determine the optimal and maximum tolerated dose and recommended Phase 2 dose, as well as evaluate the preliminary antitumor activity of TYRA-200. The SURF201 study is currently enrolling and dosing adults with unresectable locally advanced/metastatic intrahepatic cholangiocarcinoma and other advanced solid tumors with activating FGFR2 gene alterations.

TYRA-430

•
Cleared Phase 1 IND with US FDA – SURF431. TYRA-430 is an oral, investigational FGFR4/3-biased inhibitor for FGF19+/FGFR4-driven cancers. The Phase 1 study will be a multicenter, open-label, first-in-human study of TYRA-430 in advanced hepatocellular carcinoma (HCC) and other solid tumors with activating FGF/FGFR pathway aberrations (SURF431). We believe TYRA-430 has the potential to address a significant unmet need in HCC, where there are no approved biomarker-driven, targeted therapies.

Corporate

•
Strengthened Leadership Team and Board of Directors. In 2024, TYRA appointed Doug Warner, MD, as Chief Medical Officer, and Erik Goluboff, MD, as SVP, Clinical Development to lead the Company’s oncology strategy and clinical development plans. In 2025, TYRA appointed accomplished drug developer Adele Gulfo to its Board of Directors, Sinette Heys as SVP, Clinical Operations to lead the Company’s clinical operations team, and Will Charlton, MD, as SVP, Clinical Development to lead the Company’s skeletal dysplasia clinical development group.

About TYRA-300

TYRA-300 is the Company’s lead precision medicine program stemming from its in-house SNÅP platform. TYRA-300 is an investigational, oral, FGFR3-selective inhibitor currently in development for the treatment of cancer and skeletal dysplasia, including achondroplasia and hypochondroplasia. In oncology, TYRA-300 is being evaluated in mUC and IR NMIBC. In mUC, TYRA-300 is being evaluated in a multi-center, open label Phase 1/2 clinical study, SURF301 (Study in Untreated and Resistant FGFR3+ Advanced Solid Tumors) (NCT05544552). The study is designed to determine the optimal and the recommended Phase 2 dose of TYRA-300, as well as to evaluate the preliminary antitumor activity of TYRA-300. In October 2024, TYRA reported interim clinical proof-of-concept data in mUC from SURF301. TYRA has received IND clearance from the US FDA to proceed with its SURF302 clinical trial in patients with IR NMIBC. In skeletal dysplasia, TYRA-300 has demonstrated positive preclinical results in achondroplasia and hypochondroplasia, and its BEACH301 clinical trial in children with achondroplasia is now recruiting.

About TYRA-200

TYRA-200 is an oral, investigational, FGFR1/2/3 inhibitor with potency against activating FGFR2 gene alterations and resistance mutations. The Phase 1 clinical study of TYRA-200, SURF201 (Study in PrevioUsly treated and Resistant FGFR2+ Cholangiocarcinoma and Other Advanced Solid Tumors) (NCT06160752), is a multi-center, open label study designed to evaluate the maximum tolerated dose (MTD) and the recommended Phase 2 dose of TYRA-200, as well as to evaluate the preliminary antitumor activity of TYRA-200. SURF201 is currently enrolling and dosing adults with advanced/metastatic intrahepatic cholangiocarcinoma and other advanced solid tumors with activating alterations in FGFR2.

About TYRA-430

TYRA-430 is an oral, investigational FGFR4/3-biased inhibitor for FGF19+/FGFR4-driven cancers. The US FDA has cleared Tyra’s IND to proceed with a Phase 1 clinical study of TYRA-430. The Phase 1 study will be a multicenter, open-label, first-in-human study of TYRA-430 in advanced HCC and other solid tumors with activating FGF/FGFR pathway aberrations (SURF431).
