Futility Analyses Completed on CMV Phase 3 Trial in HCT Patients and Trial Continuing as Planned

Phase 1 Trial Initiated for Novel Antifungal

SAN DIEGO, March 14, 2016 (GLOBE NEWSWIRE) -- Vical Incorporated (Nasdaq:VICL) today reported financial results for the three and twelve months ended December 31, 2015. Net loss for the fourth quarter of 2015 was $2.4 million, or $0.03 per share, compared with a net loss of $4.6 million, or $0.05 per share, for the fourth quarter of 2014. Revenues for the fourth quarter of 2015 were $6.8 million, compared with revenues of $4.8 million for the fourth quarter of 2014, reflecting revenues from IPPOX for the manufacture of HIV vaccine.  This vaccine is expected to be used as a priming component of prime/boost vaccine regimens that will be evaluated in clinical trials for the prevention of HIV infection.

Vical had cash and investments of $42.0 million at December 31, 2015. The Company’s net cash use for the fourth quarter of 2015 was $1.9 million, which reflects its ongoing efforts to manage its operating expenses. The Company's net cash burn for 2015 was $7.1 million which was consistent with the Company’s prior guidance. The Company is projecting net cash burn for 2016 between $8 million and $11 million.

Program updates include:

ASP0113 CMV Vaccine

  • Enrollment in the multinational Phase 3 registration trial in 500 hematopoietic cell transplant (HCT) recipients is ongoing. Astellas has finalized the primary endpoint as a composite of overall mortality and CMV end organ disease. During the course of the trial, an independent statistician conducted a series of futility analyses based upon viral load. The final of these analyses has now been completed and the trial is continuing as planned. Both Astellas and Vical remain blinded to the results of the analyses. Astellas expects enrollment in the trial to be completed by the third quarter of 2016, with the top-line data being available in the fourth quarter of 2017.
     
  • Enrollment in the multinational Phase 2 trial in kidney transplant recipients is complete. The primary endpoint of this trial is the incidence of CMV viremia and the study is powered to show an approximately 50% reduction in CMV viremia at one year after transplantation. Top-line trial data are expected to be available in the third quarter of 2016.


HSV-2 Vaccine

  • Vical recently obtained the 9-month efficacy data from its HSV-2 Phase 1/2 study and the bivalent vaccine continued to achieve statistically significant reductions in the clinically meaningful secondary endpoint of genital lesion rate when compared to the pre-vaccination period, an effect that was durable to nine months. Neither the placebo nor the monovalent vaccine groups achieved statistical significance on this endpoint at nine months after vaccination. Vical is reviewing this encouraging data and T-cell immunogenicity results with its clinical advisory board to determine the best path forward for the program. The company intends to present the detailed 9-month data at an upcoming scientific conference.


VL-2397 Antifungal

  • Vical recently announced that enrollment has been initiated in a first-in-human Phase 1 trial of its novel antifungal, VL-2397, for invasive pulmonary aspergillosis. The randomized, double-blind, placebo-controlled trial will evaluate safety, tolerability and pharmacokinetics of VL-2397 at single and multiple ascending doses in otherwise healthy volunteers at one U.S. clinical site. The U.S. Food and Drug Administration (FDA) recently granted Vical orphan drug and qualified infectious disease product (QIDP) designation  for VL-2397 for the treatment of invasive aspergillosis. The company also presented preclinical data on VL-2397 at the Interscience Conference of Antimicrobial Agents and Chemotherapy (ICAAC) in September 2015.
