"Given the nature of this serious life-threatening condition and absence of EBV-targeted treatments today, our goal is to bring Nana-val to patients with relapsed or refractory EBV-positive PTCL as quickly as possible," said Darrel P. Cohen, M.D., Ph.D., Chief Medical Officer of Viracta. "The completion of Stage 2 enrollment of the PTCL cohort in NAVAL-1 is a major milestone for the Nana-val clinical development program. We would like to acknowledge the dedication of our study execution team and the commitment of our investigators for this achievement. We look forward to building upon our previously published positive data from the Phase 1b/2 clinical trial and reporting topline PTCL cohort data from Stage 1 of the NAVAL-1 trial in the second quarter of 2024. Additionally, we plan to meet with FDA in mid-2024 to align on requirements for accelerated approval of Nana-val in this orphan indication."

Upcoming Anticipated Milestones for the NAVAL-1 Trial of Nana-val in Patients with R/R EBV+ PTCL

Present topline Stage 1 data from both arms (in patients treated with nanatinostat with [n=10] or without [n=10] valganciclovir) in the second quarter of 2024, with an aim to clearly delineate the differentiation of Nana-val’s ‘kick and kill’ mechanism of action.
Present Stage 1 + Stage 2 data (n=21) from the R/R EBV+ PTCL cohort in patients treated with Nana-val in the third quarter of 2024.
Engage with the U.S. Food and Drug Administration (FDA) in mid-2024, to align on requirements for accelerated approval.
Enroll patients into the post-Phase 2 expansion cohort to support potential accelerated approval.
About the NAVAL-1 Trial
NAVAL-1 (NCT05011058) is a global, multicenter, clinical trial of Nana-val in patients with relapsed or refractory (R/R) Epstein-Barr virus-positive (EBV+) lymphoma. This trial employs a Simon two-stage design where, in Stage 1, participants are enrolled into one of three indication cohorts based on EBV+ lymphoma subtype. If two objective responses are achieved within a lymphoma subtype in Stage 1 (n=10), then additional patients will be enrolled in Stage 2 for a total of 21 patients. EBV+ lymphoma subtypes demonstrating promising antitumor activity in Stage 2 may be further expanded following discussion with regulators to potentially support registration.

About Nana-val (Nanatinostat and Valganciclovir)
Nanatinostat is an orally available histone deacetylase (HDAC) inhibitor being developed by Viracta. Nanatinostat is selective for specific isoforms of Class I HDACs, which are key to inducing viral genes that are epigenetically silenced in Epstein-Barr virus (EBV)-associated malignancies. Nanatinostat is currently being investigated in combination with the antiviral agent valganciclovir as an all-oral combination therapy, Nana-val, in various subtypes of EBV-associated malignancies. Ongoing trials include a pivotal, global, multicenter, open-label Phase 2 basket trial in multiple subtypes of relapsed or refractory (R/R) EBV+ lymphoma (NAVAL-1) as well as a multinational Phase 1b/2 clinical trial in patients with recurrent or metastatic (R/M) EBV+ NPC and other advanced EBV+ solid tumors.

About Peripheral T-Cell Lymphoma
T-cell lymphomas comprise a heterogeneous group of rare and aggressive malignancies, including peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) and angioimmunoblastic T-cell lymphoma (AITL). There are approximately 5,600 newly diagnosed T-cell lymphoma patients and approximately 2,600 newly diagnosed PTCL-NOS and AITL patients in the U.S. annually. Approximately 70% of these patients are either refractory to first-line therapy, or eventually experience relapse of their disease. Clinical trials are currently recommended for all lines of PTCL therapy, and most patients with R/R PTCL have poor outcomes, with median progression-free survival and median overall survival times reported to be 3.7 and 6.5 months, respectively. Approximately 40% to 65% of PTCL is associated with EBV, the incidence of EBV+ PTCL varies by geography, and reported outcomes for patients with EBV+ PTCL are inferior to those whose disease is EBV-negative. There is no approved targeted treatment specific for EBV+ PTCL, and therefore this represents a high unmet medical need.

About EBV-Associated Cancers
Approximately 90% of the world’s adult population is infected with EBV. Infections are commonly asymptomatic or associated with mononucleosis. Following infection, the virus remains latent in a small subset of cells for the duration of the patient’s life. Cells containing latent virus are increasingly susceptible to malignant transformation. Patients who are immunocompromised are at an increased risk of developing EBV-positive (EBV+) lymphomas. EBV is estimated to be associated with approximately 2% of the global cancer burden including lymphoma, nasopharyngeal carcinoma (NPC), and gastric cancer.

On February 29, 2024 SpringWorks Therapeutics, Inc. (Nasdaq: SWTX), a commercial-stage biopharmaceutical company focused on severe rare diseases and cancer, reported that the European Medicines Agency (EMA) has validated the Marketing Authorization Application (MAA) for nirogacestat, an oral gamma secretase inhibitor, for the treatment of adults with desmoid tumors (Press release, SpringWorks Therapeutics, FEB 29, 2024, View Source [SID1234640667]). If approved, nirogacestat will be the first therapy to receive marketing authorization in the European Union (EU) for the treatment of desmoid tumors. Nirogacestat previously received Orphan Drug designation from the European Commission for the treatment of soft tissue sarcoma.

"The validation of our marketing authorization application is an important step towards bringing nirogacestat to patients with desmoid tumors in the European Union who currently do not have an approved therapy," said Saqib Islam, Chief Executive Officer of SpringWorks. "We look forward to working with the EMA on this important submission."

The MAA submission is based on results from the Phase 3 DeFi trial. In DeFi, nirogacestat met the primary endpoint of improving progression-free survival (PFS), demonstrating a statistically significant improvement over placebo with a 71% reduction in the risk of disease progression (hazard ratio (HR) = 0.29 (95% CI: 0.15, 0.55); p< 0.001). Median PFS was not reached in the nirogacestat arm and was 15.1 months in the placebo arm. Confirmed objective response rate (ORR) based on blinded independent central review of Response Evaluation Criteria in Solid Tumors v1.1 was 41% with nirogacestat versus 8% with placebo (p<0.001); the complete response rate was 7% in the nirogacestat arm and 0% in the placebo arm. Nirogacestat also demonstrated early and sustained improvements in patient-reported outcomes (PROs) measured as of the cycle 10 assessment, including pain (p<0.001), desmoid tumor-specific symptoms (p<0.001), physical/role functioning (p<0.001), and overall health-related quality of life (p≤0.01). Nirogacestat exhibited a manageable safety and tolerability profile. The most common adverse events (>15%) reported in patients receiving nirogacestat were diarrhea, ovarian toxicity, rash, nausea, fatigue, stomatitis, headache, abdominal pain, cough, alopecia, upper respiratory tract infection, and dyspnea. The DeFi trial results were published in the March 9, 2023 edition of the New England Journal of Medicine and presented during a Presidential Symposium at the European Society for Medical Oncology Congress 2022.1, 2

"Desmoid tumors can have a significant impact on patients’ lives and there is a pressing need for a new treatment for patients in Europe," said Bernd Kasper, M.D., Ph.D., University of Heidelberg, Mannheim Cancer Center, Mannheim, Germany and Principal Investigator of the DeFi trial. "In the DeFi trial, nirogacestat demonstrated significant improvements across progression-free survival, objective response rate, and patient-reported outcomes, and had a safety profile that supports long-term dosing. These results support that nirogacestat will be a practice-changing therapy if approved by the EMA."

In November 2023, the U.S. Food and Drug Administration approved OGSIVEO (nirogacestat) for the treatment of adults with progressing desmoid tumors who require systemic treatment. The U.S. prescribing information includes the following Warnings & Precautions: diarrhea, ovarian toxicity, hepatotoxicity, non-melanoma skin cancers, electrolyte abnormalities, and embryo-fetal toxicity. Please see below for additional Important Safety Information.

About Desmoid Tumors

Desmoid tumors (sometimes referred to as aggressive fibromatosis, or desmoid fibromatosis) are rare, aggressive, locally invasive tumors of the soft tissues that can be serious, debilitating, and, in rare cases when vital structures are impacted, life-threatening.3,4

Desmoid tumors are most commonly diagnosed in patients between the ages of 20 and 44 years, with a two-to-three times higher prevalence in females. 5,6 In the European Union, the incidence of desmoid tumors is estimated to be approximately 3-5 cases per million per year.7

Although they do not metastasize, desmoid tumors are associated with recurrence rates of up to 77% after surgical resection.5,8,9 Desmoid tumor experts and treatment guidelines now recommend systemic therapies as first-line intervention instead of surgery for most tumor locations requiring treatment.9

About OGSIVEO (nirogacestat)

OGSIVEO (nirogacestat) is an oral, selective, small molecule gamma secretase inhibitor approved in the United States for the treatment of adult patients with progressing desmoid tumors who require systemic treatment.

OGSIVEO is not approved for the treatment of any other indication in the United States, or for any indication in any other jurisdiction by any other health authority.

SpringWorks is also evaluating nirogacestat as a potential treatment for patients with ovarian granulosa cell tumors and for patients with multiple myeloma as part of several B-cell maturation agent (BCMA) combination therapy regimens in collaboration with leaders in industry and academia.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Diarrhea: Diarrhea occurred in 84% of patients treated with OGSIVEO. Grade 3 events occurred in 16% of patients. Monitor patients and manage using antidiarrheal medications. Modify dose as recommended.
Ovarian Toxicity: Female reproductive function and fertility may be impaired in patients treated with OGSIVEO. Impact on fertility may depend on factors like duration of therapy and state of gonadal function at time of treatment. Long-term effects on fertility have not been established. Advise patients on the potential risks for ovarian toxicity before initiating treatment. Monitor patients for changes in menstrual cycle regularity or the development of symptoms of estrogen deficiency, including hot flashes, night sweats, and vaginal dryness.
Hepatotoxicity: ALT or AST elevations occurred in 30% and 33% of patients, respectively. Grade 3 ALT or AST elevations (>5 × ULN) occurred in 6% and 2.9% of patients. Monitor liver function tests regularly and modify dose as recommended.
Non-Melanoma Skin Cancers: New cutaneous squamous cell carcinoma and basal cell carcinoma occurred in 2.9% and 1.4% of patients, respectively. Perform dermatologic evaluations prior to initiation of OGSIVEO and routinely during treatment.
Electrolyte Abnormalities: Decreased phosphate (65%) and potassium (22%) occurred in OGSIVEO-treated patients. Phosphate <2 mg/dL occurred in 20% of patients. Grade 3 decreased potassium occurred in 1.4% of patients. Monitor phosphate and potassium levels regularly and supplement as necessary. Modify dose as recommended.
Embryo-Fetal Toxicity: Oral administration of nirogacestat to pregnant rats during the period of organogenesis resulted in embryo-fetal toxicity at maternal exposures below human exposure at the recommended dose of 150 mg twice daily. Advise pregnant women of the potential risk to a fetus. Advise females and males of reproductive potential to use effective contraception during treatment with OGSIVEO and for 1 week after the last dose.

"Over the course of 2023, the SL-172154 program rapidly transitioned from Phase 1A dose-escalation studies to Phase 1B dose expansion studies in PROC, HR-MDS, and TP53m AML, which enabled us to share initial efficacy data in the fourth quarter," said Taylor Schreiber, M.D., Ph.D., Chief Executive Officer of Shattuck. "We have now begun 2024 with the momentum and financial resources to expand our HR-MDS and TP53m AML studies and capitalize on the potential first-in-class opportunity that now exists in those indications. We have expanded our ongoing trials, and look forward to defining our registrational strategy following the next clinical updates expected mid-year in HR-MDS, AML, and PROC. While we will remain focused on advancing SL-172154, our pre-clinical pipeline has continued to mature, as evidenced by our recent collaboration with Ono, and publications in both Cancer Cell and Cancer Research. We look forward to providing additional updates across the portfolio over the course of 2024."

Clinical Milestones Expected in 2024
SL-172154 (SIRPα-Fc-CD40L)
•Objective response rates and duration of response based on the then-available data from the Phase 1B expansion cohorts of SL-172154 in combination with AZA in frontline HR-MDS and frontline TP53m AML expected mid-year 2024.
•Objective response rate and duration of response based on the then-available data from the Phase 1B clinical trial of SL-172154 in combination with PLD in PROC expected mid-year 2024.
•Initial combination data from the Phase 1B clinical trial of SL-172154 in combination with mirvetuximab soravtansine in PROC expected mid-year 2024.

Fourth Quarter 2023 Business Highlights and Other Recent Developments
ARC Clinical-Stage Pipeline
SL-172154 (SIRPα-Fc-CD40L)
•Completed Initial Enrollment and Expanded the Phase 1B Portion of the Ongoing Phase 1A/B Clinical Trial of SL-172154 in Frontline HR-MDS and Frontline TP53m AML Patients: This trial is evaluating the safety, tolerability, pharmacokinetics, anti-tumor activity, and pharmacodynamic effects of SL-172154 in combination with AZA in both frontline HR-MDS patients and frontline TP53m AML patients. The data from the dose-escalation portion of the clinical trial in primarily relapsed/refractory patients was presented at the 65th ASH (Free ASH Whitepaper) Annual Meeting. Initial data from the dose-expansion portion of the trial in frontline patients suggest that SL-172154 improved complete response rates relative to what would be expected historically with AZA alone in previously untreated HR-MDS (predominantly TP53m HR-MDS population) and TP53m AML. SL-172154 demonstrated an acceptable safety and tolerability profile both as monotherapy and in combination with AZA. No destructive anemia was observed. Objective response rates and duration of response based on the then-available data from the Phase 1B expansion cohorts of SL-172154 in combination with AZA in frontline HR-MDS and TP53m AML are expected mid-year 2024.
•Completed Enrollment of Ongoing Phase 1B Clinical Trial of SL-172154 in Combination with PLD in PROC Patients and Presented Positive Interim Data: This trial is evaluating the safety, tolerability, pharmacokinetics, anti-tumor activity, and pharmacodynamic effects of SL-172154 (using the selected dose of 3.0 mg/kg), in combination with PLD in patients with PROC. The initial data from this Phase 1B clinical trial in PROC patients was presented in November 2023. Initial data suggest that SL-172154 improved the response rate relative to what would be expected from PLD alone. The initial data suggest SL-172154 had an acceptable safety profile in combination with PLD. Objective response rate and duration of response based on the then-available data from the Phase 1B clinical trial of SL-172154 in combination with PLD in PROC are expected mid-year 2024.
•Continued Dosing in Phase 1B Clinical Trial of SL-172154 in Combination with Mirvetuximab Soravtansine in PROC Patients. This trial is evaluating the safety, pharmacokinetics, pharmacodynamic effects, and preliminary anti-tumor activity of SL-172154 administered in combination with mirvetuximab soravtansine in patients with PROC. Mirvetuximab soravtansine is an antibody-drug conjugate targeting folate receptor alpha (FRα), which provides for both direct tumor cell killing as well as enhanced macrophage phagocytosis through binding with Fc gamma receptors and has received accelerated approval in the United States for PROC patients whose tumors are shown to be FRα positive, defined as ≥75%, as determined by the VENTANA FOLR1 (FOLR1-2.1) Assay. Initial combination data from the Phase 1B clinical trial of SL-172154 in combination with mirvetuximab soravtansine in PROC is expected mid-year 2024.
Preclinical
•Published Acquired Resistance (AR) Model in Cancer Cell: In a recent publication in the journal Cancer Cell, the preclinical development of a mouse anti-PD1 AR model by Shattuck was shown to closely mimic the clinical and molecular signatures of those in human patients with non-small cell lung cancer (NSCLC), who have developed AR to anti-PD(L)1 therapies, including a dysregulated interferon response. Findings such as these are important to guide the identification of new targets and development of new treatment strategies for this growing unmet need.
•Published Preclinical mRNA Work in Cancer Research: In a recent study published in Cancer Research, scientists at Shattuck and Moderna demonstrated the feasibility of delivering certain hexameric, dual-sided fusion proteins as lipid-encapsulated mRNA. The expression level, duration of exposure, and efficacy in a murine anti-tumor model achieved by the mRNA delivery outperformed that of the corresponding intravenous administration of recombinant fusion proteins. These results demonstrated feasibility for delivery of complex fusion proteins generally, which may have important pharmacokinetic and pharmacoeconomic benefits for indications outside of oncology.

Upcoming Events
•Shattuck plans to attend the following investor or scientific conferences. Details are included on the Events & Presentations section of the Company’s website.
▪Cowen 44th Annual Health Care Conference (Boston, MA) March 4-6, 2024

Fourth Quarter and Full-Year 2023 Financial Results
•Cash and Cash Equivalents and Investments: As of December 31, 2023 cash and cash equivalents and investments were $130.6 million, as compared to $161.3 million as of December 31, 2022.
•Research and Development (R&D) Expenses: R&D expenses for the quarter ended December 31, 2023,were $15.2 million, as compared to $21.9 million for the quarter ended December 31, 2022. R&D expenses for the year ended December 31, 2023 were $74.3 million, as compared to $82.9 million for the year ended December 31, 2022. This decrease was primarily driven by decreases in the manufacturing of trial materials to support clinical development of our ongoing clinical trials, personnel-related costs, and lab supplies but were offset by an increase in clinical trial cost.
•General and Administrative (G&A) Expenses: G&A expenses for the quarter ended December 31, 2023 were $4.4 million, as compared to $4.8 million for the quarter ended December 31, 2022. General and administrative expenses for the year ended December 31, 2023 were $19.3 million, as compared to $21.1 million for the year ended December 31, 2022. This decrease for the full year was primarily the result of recognizing a litigation settlement of $1.4 million in 2022, and the decrease in the fourth quarter of 2023 was primarily driven by a decrease in insurance and personnel-related cost.
•Net Loss: Net loss was $17.7 million for the quarter ended December 31, 2023, or $0.41 per basic and diluted share, as compared to a net loss of $25.4 million for the quarter ended December 31, 2022, or $0.60 per basic share and diluted share. Net loss for the year ended December 31, 2023 was $87.3 million, or $2.05 per basic and diluted share, as compared to $101.9 million, or $2.41 per basic and diluted share, for the year ended December 31, 2022.
Financial Guidance
Shattuck believes its cash and cash equivalents and investments will be sufficient to fund its operations into 2026, beyond results from its Phase 1 clinical trials of SL-172154. This cash runway guidance is based on the Company’s current operational plans and excludes any additional capital that may be received, proceeds from business development transactions, and/or additional costs associated with clinical development activities that may be undertaken.

"With the completion of the Seagen acquisition in 2023, Pfizer has significantly expanded its Oncology organization to amplify its efforts to advance new standards of care and improve outcomes for patients," said Chris Boshoff, Chief Oncology Officer and Executive Vice President, Pfizer. "With the energy of our highly talented colleagues, the tremendous potential of our pipeline and scientific engine, and scale of the Pfizer enterprise, we believe we are poised to deliver on our vision of accelerating breakthroughs that help people with cancer globally live better and longer lives."

Boshoff continued, "We have a clear strategy focused on three core scientific modalities and four main types of cancer, where we have the deep expertise and knowledge to advance our leadership. With many significant catalysts expected through the first half of 2025 and beyond, our Oncology organization is well-positioned to be a critical driver of potential long-term sustainable sales and profit growth for Pfizer through the end of the decade."

During the event, Chris Boshoff and members of the Pfizer Oncology leadership team highlighted the company’s expanded capabilities and portfolio following the completion of the acquisition of Seagen in December 2023. Pfizer Oncology is focused on expanding its leadership in four main cancer types: breast cancer, including three main hormonal subtypes; genitourinary cancer, including prostate and urothelial cancers; hematology-oncology, including multiple myeloma and lymphomas, such as Hodgkin’s disease; and thoracic cancers, which includes lung and head and neck cancers.

Pfizer’s Oncology portfolio is focused on three core scientific modalities: small molecules, antibody drug conjugates (ADCs), and bispecific antibodies, including other immuno-oncology biologics. The company is progressing a next-generation ADC platform aimed at novel targets and improved, differentiated payloads, as well as investigational advanced biologics and novel combinations of medicines.

The company outlined potential significant catalysts anticipated through the first half of 2025, including:

Continued focus on four recent priority indication launches, including PADCEV (enfortumab vedotin-ejfv) in combination with pembrolizumab in locally advanced / metastatic urothelial cancer; XTANDI (enzalutamide) in nonmetastatic castration-sensitive prostate cancer (nmCSPC) with biochemical recurrence at high-risk for metastasis; TALZENNA (talazoparib) in combination with XTANDI in metastatic castration-resistant prostate cancer (mCRPC); and ELREXFIO (elranatamab-bcmm) for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy.
Seven anticipated Phase 3 readouts, including results for vepdegestrant in second-line estrogen receptor positive metastatic breast cancer (ER+ mBC) (VERITAC-2), BRAFTOVI (encorafenib) in first-line BRAF+ metastatic colorectal cancer (BREAKWATER), sasanlimab in non-muscle invasive bladder cancer (CREST), and ELREXFIO in double-class exposed relapsed/refractory multiple myeloma (MagnetisMM-5).
Six anticipated Phase 3 study starts, which includes three new trials recently initiated for key pipeline assets: atirmociclib (CDK4i) in second-line hormone receptor positive (HR+) mBC, sigvotatug vedotin (B6A; integrin beta-6 (IB6)-directed ADC) in second/third-line non-small cell lung cancer (NSCLC), and ELREXFIO in patients with multiple myeloma after their cancer progresses on anti-CD38 treatment (MagnetisMM-32 trial).
Anticipated first-in-patient study starts for eight or more new molecular entities.
During the meeting, Pfizer also shared new or updated clinical data from various pipeline programs, including atirmociclib, ELREXFIO, felmetatug vedotin (B7H4 ADC), mevrometostat (EZH2i), PD-L1 ADC (PF-08046054), and sigvatutag vedotin.

Through its strategy, by 2030, the company anticipates 8 or more potential blockbusters and expects biologics to contribute approximately 65% of Oncology revenues, compared to approximately 6% in 2023.
