Below is a look at some of the headlines for companies that made news in the healthcare sector on June 3, 2014.

Gilead Sciences, Inc. (NASDAQ: GILD)
announced updated interim results of a Phase 2 study (Study 102) evaluating GS-9973, its investigational oral inhibitor of spleen tyrosine kinase (Syk), for the treatment of patients with relapsed chronic lymphocytic leukemia (CLL). In this study, single-agent treatment with GS-9973 achieved an overall response rate of 49 percent, with an estimated progression-free survival (PFS) rate at 24 weeks of 70 percent. Detailed results will be presented today during an oral session at the 50th Annual Meeting of the American Society of Clinical Oncology (ASCO) in Chicago (Abstract #7007).

“Most CLL patients eventually relapse following treatment, underscoring the need for novel therapies targeting survival pathways that may enable patients to obtain control of their disease without requiring chemotherapy,” said Jeff Sharman, MD, lead study author and Medical Director of Hematology Research for the US Oncology Network. “The strong response rates and acceptable safety profile seen in this study suggest that GS-9973 has the potential to provide therapeutic benefit for relapsed CLL patients.”

The efficacy analysis focuses on a cohort of 41 CLL patients with a median exposure of 32 weeks (range 1-53) in Study 102. Among this cohort, the Kaplan-Meier estimated PFS rate at 24 weeks was 70 percent (95 percent CI: 51-83 percent). Median PFS and median duration of response were not reached. At the time of data snapshot, 46 percent of patients (n=19) continued GS-9973 treatment. There was a 49 percent (n=20) overall response rate, of which all were partial responses. Ninety-five percent of evaluable patients (n=37/39) experienced tumor shrinkage, including all 25 patients with a chromosome 17p deletion and/or a mutation in the TP53 gene or other genetic abnormalities that have been linked to poor prognosis. Sixty-two percent of evaluable patients (n=24) achieved at least a 50 percent tumor reduction.

The safety of GS-9973 was also assessed in a larger population of 145 CLL or non-Hodgkin lymphoma (NHL) patients with an overall median exposure of 13 weeks at the time of data snapshot. Non-hematologic Grade ≥3 adverse events included fatigue (6.9 percent); dyspnea (6.2 percent); pneumonia (4.1 percent); nausea (3.4 percent); atrial fibrillation, chest pain, dehydration, febrile neutropenia and hypoxia (2.8 percent each); and back pain, hypotension, pyrexia and sepsis (2.1 percent each). Reversible Grade ≥3 transaminase elevations (a measure of liver function) were reported in 14 percent of patients.

Based on these data, Gilead plans to initiate new CLL study cohorts to include patients who have relapsed following treatment with other inhibitors of the b-cell receptor (BCR) pathway.

Provectus Biopharmaceuticals, Inc. (NYSE MKT: PVCT)
, a development-stage oncology and dermatology biopharmaceutical company, announced today that data on its investigational agent PV-10 for intralesional (IL) treatment of solid tumors were featured in two presentations in the Poster Highlights Session, Melanoma/Skin Cancers, on June 2, 2014 during the American Society of Clinical Oncology (ASCO) annual meeting in Chicago, IL.

The first highlighted abstract, presented by Sanjiv S. Agarwala, MD, of the St. Luke's Cancer Center, Bethlehem, PA, entitled "Efficacy of intralesional rose bengal in patients receiving injection in all existing melanoma in phase II study PV-10-MM-02" (abstract 9027), may be viewed at: http://abstracts.asco.org/144/AbstView_144_132320.html.

The second highlighted abstract, presented by Amod A. Sarnaik, MD, of Moffitt Cancer Center, Tampa, FL, entitled "Assessment of immune and clinical efficacy after intralesional PV-10 in injected and uninjected metastatic melanoma lesions" (abstract 9028), may be viewed at: http://abstracts.asco.org/144/AbstView_144_132288.html.

In the phase 2 PV-10 trial, when all existing lesions were injected with PV-10, tumors were no longer detectable (complete response) in 50% of the patients (Confidence Interval: 31-69%). This subgroup analysis supports the potential of PV-10 as a single agent and provides a rationale for a PV-10 phase 3 randomized controlled trial in locally advanced melanoma patients.

This phase 3 randomized controlled trial of PV-10 in patients with unresectable locally advanced cutaneous melanoma will assess response to PV-10 vs that of systemic chemotherapy in patients who have disease limited to cutaneous and subcutaneous sites and who have failed or are ineligible for systemic immunotherapy. Progression-free survival and complete response rate will be assessed using standard criteria (RECIST 1.1). Overall survival and exploratory assessment of patient reported outcomes related to lesion pain and other melanoma symptoms will also be assessed. The study is expected to commence this year, and will allow for interim assessment when 50% of the required events have occurred (i.e., disease progressions).

The Moffitt abstract provided interim results of a pilot clinical trial designed to investigate the local and immunologic effects of tumor ablation with PV-10. Lead author, Dr. Sarnaik, noted “In the peripheral blood of patients after PV-10 injection, we saw a significant increase in circulating T-cells, including CD3+ and cytotoxic CD8+ cells. This suggests an immunologic-mediated antitumor response is engendered by PV-10. We are hoping to undertake combination trials that combine PV-10 with the promising systemic immunotherapies being developed by our medical oncology colleagues.”

Eric Wachter, Ph.D., Chief Technology Officer of Provectus, observed that these results delineate two development paths to generate data sufficient for a new drug application (NDA) for PV-10 in melanoma.

Dr. Wachter concluded, “Our focus this year will be initiation of the phase 3 randomized controlled trial. We also expect to begin the more exploratory combinatorial work that potentially addresses the needs of patients with more advanced metastatic disease.”
