Viracta Therapeutics Reports Third Quarter 2024 Financial Results and Provides Business Update

 

- Reprioritized resources to reduce costs and enhance focus on Nana-val’s development program in relapsed or refractory EBV-positive peripheral T-cell lymphoma (PTCL) -

- On track to report data from expansion phase of the Phase 2 NAVAL-1 clinical trial of Nana-val in the first half of 2025 -

- Determined recommended Phase 2 dose of Nana-val in patients with advanced EBV-positive solid tumors-

 

SAN DIEGO, November 13, 2024 – Viracta Therapeutics, Inc. (Nasdaq: VIRX), a clinical-stage precision oncology company focused on the treatment and prevention of virus-associated cancers that impact patients worldwide, today reported financial results for the third quarter of 2024 and provided a business update.

“Last quarter, based on productive feedback from FDA, we announced a sharpened focus on the second-line EBV-positive PTCL subpopulation in the NAVAL-1 trial’s expansion phase, which is ongoing,” said Mark Rothera, President and Chief Executive Officer of Viracta. “To optimally support both the NAVAL-1 trial as well as a randomized controlled trial that we are planning for the second half of next year and reduce cash burn, we recently announced a reprioritization of resources intended to right-size our organization and further reduce our operating expenses. With a clearly defined regulatory path forward for Nana-val, we believe this will allow us to be efficient while we work toward the possible submission of a New Drug Application in 2026 and seek to introduce the first EBV-targeted therapy for lymphoma patients, subject to obtaining requisite funding.”

“We are pleased to have determined a recommended Phase 2 dose for Nana-val in patients with advanced EBV-positive solid tumors,” said Darrel P. Cohen, M.D., Ph.D., Chief Medical Officer of Viracta.

“Although the EBV-positive solid tumor program has been paused, clinical development in this patient population is ready for Phase 2, with additional financing or with a partner, using nanatinostat and valganciclovir doses that were well tolerated with evidence of antitumor activity.”

Clinical Trial Updates and Anticipated Milestones

Phase 1b/2 trial of Nana-val (nanatinostat in combination with valganciclovir) in patients with recurrent/metastatic (R/M) Epstein-Barr virus-positive (EBV+) nasopharyngeal carcinoma (NPC) and other advanced EBV+ solid tumors (Study 301)

Clinical Trial Update:

Phase 2 NAVAL-1 trial of Nana-val (nanatinostat in combination with valganciclovir) in patients with relapsed or refractory (R/R) Epstein-Barr virus-positive (EBV+) lymphoma

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 potentially registrational, 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.

About Viracta Therapeutics, Inc.

Viracta is a clinical-stage precision oncology company focused on the treatment and prevention of virus-associated cancers that impact patients worldwide. Viracta’s lead product candidate is an all-oral combination therapy of its proprietary investigational drug, nanatinostat, and the antiviral agent valganciclovir (collectively referred to as Nana-val). Nana-val is currently being evaluated in multiple ongoing clinical trials, including a potentially registrational, global, multicenter, open-label Phase 2 basket trial for the treatment of multiple subtypes of relapsed or refractory (R/R) Epstein-Barr virus-positive (EBV+) lymphoma (NAVAL-1), as well as a multinational, open-label Phase 1b/2 clinical trial for the treatment of patients with recurrent or metastatic (R/M) EBV+ nasopharyngeal carcinoma (NPC) and other advanced EBV+ solid tumors. Viracta is also pursuing the application of its “Kick and Kill” approach in other virus-related cancers.
