PROVECTUS BIOPHARMACEUTICALS RECEIVES SECOND CANCER COMBINATION THERAPY PATENT FROM THE UNITED STATES PATENT AND TRADEMARK OFFICE

On November 7, 2017 Provectus Biopharmaceuticals, Inc. (OTCQB: PVCT, www.provectusbio.com), ("Provectus" or the "Company"), a clinical-stage biotechnology company leading the development of the first small molecule oncolytic immunotherapy, PV-10, as an investigational single agent for locally advanced disease as well as in combination with another agent for widely metastatic disease, both for multiple cancer indications, reported the United States Patent and Trademark Office (the "USPTO") has granted U.S. patent ("USP") 9,808,524 for the combination of intralesional ("IL") PV-10 with systemic immunomodulatory therapy, including anti-PD-1 and anti-PD-L1 agents, for the treatment of melanoma and cancers of the liver (Press release, Provectus Pharmaceuticals, NOV 7, 2017, View Source [SID1234521816]). This new patent is a continuation of USP 9,107,887, Provectus’ first cancer combination therapy patent granted by the USPTO in 2015. Pfizer, Inc. is a co-assignee on both patents.

PV-10 is an injectable formulation of rose bengal disodium, and represents nearly a decade of work by Provectus to optimize the synthetic process for manufacturing rose bengal and its related halogenated xanthene analogs to meet modern global requirements for pharmaceutical use. IL injection of PV-10 can induce immunogenic cell death that results in tumor-specific reactivity in circulating CD8+ T cells.

Provectus recently presented preliminary results from the Company’s ongoing Phase 1b/2 study of IL PV-10 in combination with KEYTRUDA (pembrolizumab), Merck’s systemic anti-PD-1 (programmed death receptor-1) antibody agent, at the Society for Melanoma Research 2017 Congress, held in Brisbane, Australia on October 18-21. Adverse events were consistent with the established patterns for each drug, and there were no unexpected toxicities or evidence of compounded toxicity. Preliminary overall efficacy included 10% complete response, 50% objective response, and 60% clinical benefit, with the highest responses observed in Stage IV M1c melanoma patients (all per RECIST 1.1).

The Phase 1b portion of the study continues to enroll patients at clinical sites in the U.S. and Australia (NCT02557321); Stage IV patients with at least one injectable lesion who are candidates for KEYTRUDA are eligible. A total of up to 24 patients would receive the combination of IL PV-10 and KEYTRUDA every three weeks for five cycles (i.e., for up to 12 weeks, with no further PV-10 administered after week 12), followed by only KEYTRUDA every three weeks for up to 24 months. The primary endpoint for the Phase 1b trial is safety and tolerability; objective response rate and progression-free survival are key secondary endpoints (both assessed via RECIST 1.1 after five treatment cycles, and then every 12 weeks thereafter).

Dominic Rodrigues, Chairman of the Company’s Board of Directors, said, "This patent continues our work to expand intellectual property protection of PV-10, and to augment the potential commercial value of Provectus’ clinical development program in cancer combination therapy."

Mr. Rodrigues also said, "Provectus’ ongoing Phase 1b study of PV-10 and KEYTRUDA is based on a rational study design for Stage IV melanoma patients with visceral disease, and provides for the investigation of the potential for small molecule oncolytic immunotherapy to demonstrate orthogonality to and synergy with checkpoint inhibition, combination therapy measures of safety and efficacy, respectively."

Mr. Rodrigues concluded, "Numerous players around the world, with approved or investigational drugs within each class of systemic immuno-oncology agent, are pursuing smaller and smaller pieces of market share because drugs within each of these classes may be similar or, indeed, equivalent. Assuming a rational clinical basis for combination, another form of differentiation is needed to gain and protect market share for cancer combination therapy. We believe this aspect of our company’s patent estate provides for proprietary combinations with protected agents."

"The third quarter of 2017 has been a productive one for Aclaris. In August, we closed the acquisition of Confluence Life Sciences, Inc. ("Confluence"), and we continue to prepare for our December 24th PDUFA date for A-101 40% Topical Solution for the treatment of seborrheic keratosis," said Dr. Neal Walker, President and Chief Executive Officer of Aclaris.

Clinical Pipeline Update
·
A-101 40% Topical Solution
o
In September, published results from a Phase 2 clinical trial evaluating two concentrations (40% and 32.5%) of its drug candidate A-101 for the treatment of facial seborrheic keratosis (SK) lesions in the journal Dermatologic Surgery. In the trial, A-101 achieved statistically significant improvement in clearing SK lesions on the face in a dose-related fashion. A-101 was well tolerated at both concentrations studied.
o
The FDA’s Prescription Drug User Fee Act (PDUFA) action date for the New Drug Application (NDA) is December 24, 2017. If approved, A-101 40% Topical Solution would be the first FDA-approved medication for SK.

·
A-101 45% Topical Solution
o
In June, initiated two Phase 2 clinical trials of A-101 45% Topical Solution (A-101 45%) for the treatment of common warts. The Phase 2 clinical trials are designed to evaluate the safety, tolerability and dose frequency of A-101 45% compared with placebo in adult and pediatric patients.

o
Enrollment in both phase 2 trials has been completed and 316 patients have been enrolled in the two double-blinded trials which are being conducted at 34 investigational centers within the United States. Aclaris expects to report data from these two trials in the first half of 2018.

·
JAK Inhibitors
o
In October, initiated a Phase 2 clinical trial of ATI-50002, a topical Janus Kinase (JAK) 1/3 inhibitor (ATI-50002 Topical) for the treatment of alopecia areata (AA). This trial will evaluate the pharmacokinetics, pharmacodynamics and safety of ATI-50002 Topical compared with placebo in 12 patients with AA. This randomized, double-blind clinical trial is being conducted at two investigational centers within the United States, and data is expected to be available in the first half of 2018.
o
In November, initiated a Phase 2 open-label clinical trial of ATI-50002 Topical for the treatment of AA. This trial will evaluate the effect of ATI-50002 Topical on the regrowth of eyebrows in up to 24 patients with AA. This trial is being conducted at two investigational centers in Sydney and Melbourne, Australia, and data is also expected to be available in the first half of 2018.
o
Continue plans to initiate a Phase 2 dose ranging trial of ATI-50002 Topical for the treatment of AA next week. This study is a randomized, double-blinded, parallel-group, vehicle controlled trial and plan to enroll approximately 120 patients at 20 investigational centers within the United States. Data is expected to be available by year end 2018.
o
Continue plans to initiate a Phase 2 open-label clinical trial of ATI-50002 Topical for the treatment of vitiligo by the end of 2017.
o
Now plan to initiate a Phase 2 dose ranging trial of ATI-50001, an oral JAK inhibitor, for the treatment of AA in the first half of 2018.
o
Continue to develop another series of topical JAK inhibitors for the treatment of androgenetic alopecia (AGA).

The increase of $3.7 million was primarily attributable to a $1.2 million increase in expenses related to the Phase 2 clinical trials of A-101 45%, a $1.3 million increase in personnel-related expenses, including stock-based compensation, due to increased

headcount, a $0.9 million increase in preclinical and clinical trial development expenses related to the JAK inhibitor technology and a $0.9 million increase in medical affairs expenses and other costs, including early stage drug discovery, offset in part by a $1.2 million decrease in clinical costs for A-101 40% Topical Solution resulting from the completion of Phase 3 clinical trials in November 2016.

o
General and administrative expenses were $8.1 million for the third quarter of 2017, compared to $3.7 million for the third quarter of 2016.
