PART

I

ITEM 1. BUSINESS.

General

Provectus

Biopharmaceuticals, Inc., a Delaware corporation (together with its subsidiaries, “Provectus” or the “Company”),

is a clinical-stage biotechnology company developing immunotherapy medicines for different diseases, with the aims of maximizing

the curative impact of these medicines and achieving immunity from treated disease. These investigational drugs are based on an

entire, wholly-owned, family of small molecules called halogenated xanthenes (“HXs”); our lead HX molecule

is named rose bengal disodium (“RBD”). Former scientists from the U.S. Department of Energy’s Oak Ridge

National Laboratory founded Provectus in 2002, identifying and advancing RBD’s dark-effect therapeutic potential

and developing RBD and HXs into proprietary molecules. Starting in 2017, new science and business leadership pivoted and then

expanded drug discovery and development, targeting global patient populations in a number of disease areas and indications made

viable by RBD’s immunotherapeutic potential and new routes of administration.

Science

RBD possesses an

innovative physical chemistry science with broad-spectrum prophylactic and therapeutic medical applications. The prerequisite

mechanistic step for these immunotherapies is direct contact between RBD and disease that may lead to disease death repair, RBD

treatment-specific innate immune activation, and disease-specific functional adaptive immune response. RBD displays

consistent mechanistic behavior across different indications of a disease and across different disease areas, with the

potential to be a multi-disease treatment platform and a universal contributor to different medical treatments.

Drug

Discovery and Development Strategy

New company leadership has

a compelling vision of accessible and affordable, safe, broad-spectrum small molecule immunotherapies. Provectus’ legacy

intralesional (IL) oncology clinical program was pivoted and enhanced to pursue U.S. Food and Drug Administration (“FDA”)

and/or Australia’s Therapeutics Good Administration (“TGA”) regulatory advancement for rare or refractory cancers

of the skin and cancers of the liver in both single-agent and combination therapy settings.

Drug development was expanded to pursue

proof-of-concept of systemic RBD administration. Routes of administration and target diseases being developed

include oral (“PO”) hematology in relapsed and refractory adult and pediatric leukemias, and PO

oncology for prophylactic and/or therapeutic RBD in high-risk adult solid tumor cancers. Drug discovery into RBD

treatment has also been deepened to explore different disease areas. Target diseases include virology, such as SARS-CoV-2

(COVID-19); microbiology, such as antibiotic-resistant gram-negative bacteria; ophthalmology, such as diseases of the cornea;

and dermatology, such as combination therapy with systemic biologics for psoriasis and atopic dermatitis.

RBD

and HX Intellectual Property (“IP”)

RBD, the active pharmaceutical ingredient

(API) in our current investigational immunotherapy medicines, is a systemically-active, environmentally-adaptive stable,

and selective small molecule. RBD has a nominal formula of 4,5,6,7-tetrachloro-2’,4’,5’,7’-tetraiodofluorescein

disodium. Rose bengal drug substance (“RB DS”) is produced by Provectus’ Quality-by-Design (“QbD”)

manufacturing process, which avoids the formation of uncontrolled impurities generally (and also proprietarily) known to be present

in commercial-grade rose bengal, and follows International Council for Harmonisation of Technical Requirements for Pharmaceuticals

for Human Use (“ICH”) Guidelines for pharmaceutical ingredients and current Good Manufacturing Practices (“cGMP”)

regulations. Multiple Provectus cGMP RB DS lots have surpassed multi-year stability testing.

The

Company’s science and molecules are currently protected by global intellectual property that includes composition of matter,

manufacturing methods and techniques, pharmaceutical synthesis standards, trade secrets, and concomitant combination therapy use

for different disease areas.

U.S.

PV-10

Product Pipeline

PV-10

is an injectable pharmaceutical formulation of RBD and registration study-ready investigational drug product (“PV-10

DP”). Multiple lots of PV-10 DP have surpassed multi-year stability testing, respectively. PV-10 DP is shipped,

stored, and used at room temperature. Provectus has developed two clinical-stage formulations of PV-10: an IL administration for

oncology (10% RBD) for the treatment of cancers of the skin and cancers of the liver, and topical (“top.”) application

for dermatology (0.01% RBD) for the treatment of inflammatory dermatoses (psoriasis, atopic dermatitis, and actinic keratosis).

A third formulation is under development for a currently proprietary disease area. Research into new routes of RBD administration

and formulations of PV-10 is ongoing, including PO, intranasal (“IN”), top., and/or intravenous (“IV”)

for hematology, oncology, virology, microbiology, and/or ophthalmology.

2020

Activity

Data

from the Company’s clinical trial of PV-10 as a single-agent and in combination with immune checkpoint blockade for the

treatment of primary or metastatic tumors of the liver (NCT00986661) was uploaded to the SIR 2020 ePoster Gallery of the canceled

Society of Interventional Radiology (“SIR”) 2020 Annual Scientific Meeting, held March 28-April 2, 2020 in Seattle,

Washington: “Oncolytic immunotherapy of hepatic tumors with intralesional rose bengal disodium.”

The

Company expanded its sponsored research program with Aru Narendran, MD, PhD, Professor, Departments of Pediatrics, Oncology, Biochemistry

& Molecular Biology, and Physiology & Pharmacology at the Cumming School of Medicine of the University of Calgary in Calgary,

Alberta, Canada. Under ongoing collaboration with Provectus, the Narendran research team has produced preliminary findings that

show oral dosing of RBD is effective and well tolerated in an in vivo pediatric leukemia murine model. Data from this work

are currently being prepared for publication. As part of the sponsored research expansion, the Narendran team would investigate

oral dosing of RBD in in vivo murine models for the treatment of refractory adult solid tumors that are high-risk phenotypes

and have high metastatic potential. These cancer types will include head and neck, breast, pancreatic, liver, and colorectal.

The

Company initiated a new sponsored research program with Michio Kurosu, PhD, Professor, Department of Pharmaceutical Sciences at

the College of Pharmacy of the University of Tennessee Health Science Center (“UTHSC”) in Memphis, Tennessee to investigate

RBD targeting of multi-drug resistant (“MDR”) bacteria. Dr. Kurosu’s team would undertake in vitro studies

on the spectrum of RBD activity against drug-susceptible and drug-resistant bacterial strains, synergistic activity of combinations

of RBD and FDA-approved antibiotics for Gram-negative bacteria, the mutation frequency of

RBD against bacterial strains, measuring spontaneous bacterial mutations for RBD and these combinations, and gene analyses of

mutant bacterial strains to understand resistance mechanisms.

in checkpoint-refractory patients,” was presented by Dr. Jonathan Zager, Chief Academic Officer at Moffitt Cancer Center,

and a surgical oncologist and Senior Member in Moffitt’s Departments of Cutaneous Oncology and Sarcoma.

Competition

In

general, the pharmaceutical and biotechnology industries are competitive, characterized by steady and sometimes disruptive advances

in products and technology. A number of companies have developed and continue to develop products that address the areas we have

targeted. Some of these companies are pharmaceutical companies and biotechnology companies that are international in scope and

very large in size, while others are small companies that have been successful in one or more areas we are targeting. Existing

or future pharmaceutical, device, or other competitors may develop products that accomplish similar functions to our technologies

in ways that may be less expensive, receive faster regulatory approval, or receive greater market acceptance than our products.

Many of our competitors have been in existence longer than we have, have greater capital resources, broader internal structure

for research, development, manufacturing and marketing, and may be further along in their respective product cycles.

Federal

Regulation of Therapeutic Products

All

of the prescription drug candidates we currently contemplate developing will require approval by the FDA prior to sales within

the U.S. and by comparable international governmental healthcare regulatory agencies prior to sale outside the U.S. The FDA and

comparable international agencies impose substantial requirements on the manufacturing and marketing of pharmaceutical products.

These agencies and other entities regulate, among other things, research and development activities and the testing, manufacturing,

quality control, safety and effectiveness claims, labeling, storage, record keeping, approval, advertising, and promotion of our

prescription drug candidates. While we attempt to minimize and avoid significant regulatory bars when formulating our products,

some degree of regulation from these regulatory agencies is unavoidable.

The

regulatory process required by the FDA, through which our prescription drug candidates must successfully pass before they may

be marketed in the U.S., generally involves pre-clinical laboratory and animal testing, submission of an application that must

become effective before clinical trials may begin, adequate and well-controlled human clinical trials to establish the safety

and efficacy of the product for its intended indication, and FDA approval to market a given product for a given indication after

the appropriate application has been filed. For pharmaceutical products, pre-clinical tests include laboratory evaluation of the

product, its chemistry, formulation and stability, as well as in vitro and animal studies to assess the potential safety

and efficacy of the product. We will require sponsored work to be conducted in compliance with pertinent local and international

regulatory requirements, including those providing for Institutional Review Board approval, national governing agency approval,

and patient informed consent, using protocols consistent with ethical principles stated in the Declaration of Helsinki and other

internationally recognized standards and delineated by ICH Good Clinical

Practice (“GCP”) standards.

If

the FDA is satisfied with the results and data from pre-clinical tests, it will authorize human clinical trials. Human clinical

trials traditionally are conducted in three sequential phases which may overlap. Each of the three phases involves testing and

study of specific aspects of the effects of the investigational product on human subjects, including testing for safety, dosage

tolerance, side effects, absorption, metabolism, distribution, excretion, and clinical efficacy.

Phase

1 clinical trials include the initial introduction of an investigational new drug into humans, or via a new route of administration

or new organ system if previously investigated in humans. These studies are closely monitored and may be conducted in patients

but may also be conducted in healthy volunteer subjects. These studies are designed to determine the metabolic and pharmacologic

actions of the drug in humans, the side effects associated with increasing doses, and, if possible, to gain early evidence on

effectiveness. While the FDA can cause us to end clinical trials at any phase due to safety concerns, Phase 1 clinical trials

are primarily concerned with safety issues. We also attempt to obtain sufficient information about the drug candidate’s

pharmacokinetics and pharmacological effects during Phase 1 clinical trials to permit the design of scientifically valid, Phase

2 studies.

Phase

1 studies also evaluate drug metabolism, structure-activity relationships, and the mechanism of action in humans. These studies

also determine which investigational drugs are used as research tools to explore biological phenomena or disease processes. The

total number of subjects included in Phase 1 studies varies with the drug but is generally in the range of 10 to 80.

Phase

2 clinical trials include early controlled clinical studies conducted to obtain preliminary data on the effectiveness of the drug

for a particular indication or indications in patients with the disease or condition. This phase of testing also helps determine

the common short-term side effects and risks associated with the drug. Phase 2 studies are often randomized controlled studies

that are closely monitored and conducted in a relatively small number of patients, usually involving up to several hundred people.

Phase

3 studies are expanded controlled and uncontrolled trials. They are performed after preliminary evidence suggesting effectiveness

of the drug has been obtained in Phase 2 and are intended to gather definitive information about effectiveness and safety that

is needed to evaluate the overall benefit-risk relationship of the drug. Phase 3 studies also provide an adequate basis for extrapolating

the results to the general population and transmitting that information in the physician labeling. Phase 3 studies usually include

several hundred to several thousand people.

We

have established a core clinical development team and have been working with external and FDA-experienced consultants to assist

us in developing product-specific development and approval strategies, preparing the required submittals, guiding us through the

regulatory process, and providing input into the design and site selection of human clinical studies.

The

testing and approval process requires substantial time, effort, and financial resources, and we may not obtain FDA approval on

a timely basis, if at all. Success in preclinical or early-stage clinical trials does not assure success in later-stage clinical

trials. The FDA or research institution conducting the trials may suspend clinical trials or may not permit trials to advance

from one phase to another at any time for various reasons, including a finding that the subjects or patients are being exposed

to an unacceptable health risk. Once issued, the FDA may withdraw a prescription drug approval if we do not comply with pertinent

regulatory requirements and standards or if problems are identified after the product reaches the market. If the FDA grants approval

of a prescription drug candidate, the approval may impose limitations, including limits on the indicated uses for which we may

market a drug product. In addition, the FDA may require additional testing and surveillance programs to monitor the safety and/or

effectiveness of approved drug products that have been commercialized, and the agency has the power to prevent or limit further

marketing of a product based on the results of these post-marketing programs. Further, later discovery of previously unknown problems

with a drug product may result in restrictions on the product, including withdrawal from the market.

Marketing

our prescription drug candidates abroad will require similar regulatory approvals by equivalent national authorities and is subject

to similar risks. To expedite development, we may pursue some or all of our initial clinical testing and approval activities outside

the U.S., and in particular in those countries where our prescription drug candidates may have substantial medical and commercial

relevance. In some such cases, any resulting drug products may be brought to the U.S. after substantial offshore experience is

gained. Accordingly, we intend to pursue any such development in a manner consistent with U.S. and ICH standards so that the resultant

development data is maximally applicable for potential global approval.

Board

of Director Change

On

July 11, 2020, the Company announced that Jan Koe had resigned from the Board of Directors (the “Board”). His resignation

was not due to any disagreement with the Company on any matter relating to the Company’s operations, policies or practices.

Mr. Koe’s resignation was contemplated by the Amended and Restated Definitive Financing Commitment Term Sheet effective

as of March 19, 2017, entered into between the Company and a group of the Company’s stockholders (the “PRH Group”),

which set forth the terms on which the PRH Group would provide financing to the Company (the “2017 Term Sheet”).

On

July 20, 2020, the Company added Webster Bailey to fill this vacant spot on the Board.

Human

Capital Resources

We

have two full-time employees. We also engage independent contractors, who currently serve as COO, director of clinical operations,

senior scientist, clinical research associates, project manager, information technology manager, controller, patient advocacy

manager, and database manager.

We

believe the Company’s success depends on its ability to attract, develop and retain key personnel. The skills, experience

and industry knowledge of key employees and contractors significantly benefit our operations and performance. The Company’s

Board of Directors and management oversee various employee and contractor initiatives.

Employee

health and safety in the workplace is one of the Company’s core values. The COVID-19 pandemic has underscored for us the

importance of keeping our employees and contractors safe and healthy. In response to the pandemic, the Company has taken actions

aligned with the World Health Organization and the Centers for Disease Control and Prevention to protect its workforce so they

can more safely and effectively perform their work.

ITEM 1A. RISK FACTORS.

Our

business and its future performance may be affected by various factors, the most significant of which are discussed below.

We

are a clinical-stage drug company, have no prescription drug products approved for commercial sale, have incurred substantial

losses, and expect to incur substantial losses and negative operating cash flow for the foreseeable future.

We

are a clinical-stage drug company that has no prescription drug products approved for commercial sale. We have never generated

any substantial revenues and may never achieve substantial revenues or profitability. As of December 31, 2020, we have incurred

net losses of approximately $240 million in the aggregate since inception in January 2002. We expect to incur substantial losses

and negative operating cash flow for the foreseeable future. We may never achieve or maintain profitability, even if we succeed

in developing and commercializing one or more of our prescription drug candidates. We also expect to continue to incur significant

operating expenditures and anticipate that our operating and capital expenses may increase substantially in the foreseeable future

as we continue to develop and seek regulatory approval for our prescription drug candidates PV-10 and PH-10, implement additional

internal systems and infrastructure, and hire additional personnel.

We

also expect to experience negative operating cash flow for the foreseeable future as we fund our operating losses and any future

capital expenditures. As a result, we will need to generate significant revenues in order to achieve and maintain profitability.

We may not be able to generate these revenues or achieve profitability in the future. Our failure to achieve or maintain profitability

could negatively impact the value of our common stock.

We

need additional capital to conduct our operations and commercialize and/or further develop our prescription drug candidates in

2021 and beyond, and our ability to obtain the necessary funding is uncertain.

We

need additional capital in 2021 and beyond to continue developing and seeking to commercialize our drug product candidates. We

intend to continue with the development of PV-10 and PH-10 on the basis of historical, ongoing, and prospective clinical study

and/mechanism, of action results.

We

have based our estimate of capital needs on assumptions that may prove to be wrong, and we cannot assure you that estimates and

assumptions will remain unchanged. On December 31, 2019, our Board approved a Definitive Financing Term Sheet (the “2020

Term Sheet”), which set forth the terms under which we will use our best efforts to arrange for financing of a maximum of

$20,000,000 (the “2020 Financing”). We intend to acquire additional funding through the 2020 Financing. We may also

seek capital from public or private equity or debt financings or other financing sources that may be available. As of December

31, 2020, we have raised $3,325,000 through the 2020 Financing.

Such

additional financing may not be available on acceptable terms, or at all. As discussed in more detail below, additional equity

financing could result in significant dilution to stockholders. Further, in the event that additional funds are obtained through

licensing or other arrangements, these arrangements may require us to relinquish rights to some of our products, product candidates,

and technologies that we would otherwise seek to develop and commercialize ourselves. If sufficient capital is not available,

we may be required to delay, reduce the scope of, or eliminate one or more of our programs, any of which could have a material

adverse effect on our business and may impair the value of our patents and other intangible assets.

There

is substantial doubt as to our ability to continue as a going concern.

Our

cash and cash equivalents were $97,231 at December 31, 2020, compared with $590,706 at December 31, 2019. We continue to incur

significant operating losses and management expects that significant on-going operating expenditures will be necessary to successfully

implement our business plan and develop and market our products. These circumstances raise substantial doubt about our ability

to continue as a going concern for a period of one year from the date that the consolidated financial statements included elsewhere

in this Annual Report on Form 10-K are issued. Implementation of our plans and our ability to continue as a going concern will

depend upon our ability to develop PV-10 and PH-10, and to raise additional capital.

Management

believes that we have access to capital resources through possible public or private equity offerings, including the 2020 Financing,

exchange offers, debt financings, corporate collaborations or other means. If we are unable to raise sufficient capital, we will

not be able to pay our obligations as they become due.

Our

investigational drug product candidates are at an early to mid-stage of development and may never obtain U.S. or international

regulatory approvals required for us to commercialize our investigational drug product candidates.

We

will need approval of the FDA to commercialize our investigational drug product candidates in the U.S. and approvals from FDA-equivalent

regulatory authorities in international jurisdictions to commercialize our investigational drug product candidates there.

We

are continuing to pursue clinical development of our most advanced drug product candidates, PV-10 and PH-10, for use as treatments

for specific disease indications. The continued and further development of these drug product candidates will require significant

additional research, formulation and manufacturing development, and pre-clinical and extensive clinical testing prior to their

regulatory approval and commercialization. Pre-clinical and clinical studies of our drug product candidates may not demonstrate

the safety and efficacy necessary to obtain regulatory approvals. Pharmaceutical and biotechnology companies have suffered significant

setbacks in advanced clinical trials, even after experiencing promising results in earlier trials. Pharmaceutical products that

appear to be promising at early stages of development may not reach the market or be marketed successfully for a number of reasons,

including a product may be found to be ineffective or have harmful side effects during subsequent pre-clinical testing or clinical

trials, a product may fail to receive necessary regulatory clearance, a product may be too difficult to manufacture on a large

scale, a product may be too expensive to manufacture or market, a product may not achieve broad market acceptance, others may

hold proprietary rights that will prevent a product from being marketed, and others may market equivalent or superior products.

Satisfaction

of the FDA’s regulatory requirements typically takes many years, depends upon the type, complexity and novelty of the product

candidate and requires substantial resources for research, development and testing. We cannot predict whether our research and

clinical approaches will result in drugs that the FDA considers safe for humans and effective for indicated uses. The FDA has

substantial discretion in the drug approval process and may require us to conduct additional nonclinical and clinical testing

or to perform post-marketing studies. The approval process may also be delayed by changes in government regulation, future legislation

or administrative action or changes in FDA policy that occur prior to or during our regulatory review. Delays in obtaining regulatory

approvals may delay commercialization of, and our ability to derive revenues from, our prescription drug candidates, impose costly

procedures on us, and diminish any competitive advantages that we may otherwise enjoy.

Our

research and product development efforts may not be successfully completed and may not result in any successfully commercialized

drug products. Further, after commercial introduction of a new drug product, discovery of problems through adverse event reporting

could result in restrictions on the product, including withdrawal from the market and, in certain cases, civil or criminal penalties.

Even

if we comply with all FDA requests, we cannot be sure that we will ever obtain regulatory clearance for any of our drug product

candidates. Failure to obtain FDA approval of any of our prescription drug candidates will severely undermine our business by

reducing our number of salable drug products and, therefore, corresponding revenues.

In

international jurisdictions, we must receive approval from the appropriate regulatory authorities before we can commercialize

our prescription drug candidates. International regulatory approval processes generally include all of the risks associated with

the FDA approval procedures described above.

Before

obtaining regulatory approval for the sale of our drug product candidates, including PV-10 and PH-10, we must conduct additional

clinical trials to demonstrate the safety and efficacy of our drug product candidates. Clinical testing is expensive, difficult

to design and implement, can take many years to complete and is uncertain as to timing and outcome. Competition in clinical development

has made it difficult to enroll patients at an acceptable rate in some of our clinical trials. Advances in medical technology

could make our prescription drug candidates obsolete prior to completion of clinical testing. A failure of one or more of our

clinical trials may occur at any stage of testing. The outcome of pre-clinical testing and early clinical trials may not be predictive

of the success of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. Moreover,

pre-clinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed

their product candidates performed satisfactorily in pre-clinical studies and clinical trials have nonetheless failed to obtain

marketing approval for their products. Product candidates in later stages of clinical trials may fail to show the desired safety

and efficacy characteristics despite having progressed satisfactorily through pre-clinical studies and initial clinical testing.

A number of companies in the pharmaceutical and biotechnology industries, including those with greater resources and experience,

have suffered significant setbacks in Phase 3 clinical development, even after seeing promising results in earlier clinical trials.

Our

research and development expenses may increase in connection with expanding clinical trials of our product candidates in existing

indications and undertaking clinical trials of our product candidates in new indications. Because successful development of our

drug product candidates is uncertain, we are unable to estimate the actual funds required to complete research and development

and commercialize our products under development.

Negative

or inconclusive results of our future clinical trials of PV-10 and PH-10, or any other clinical trial we conduct, could cause

the FDA to require that we repeat or conduct additional clinical studies. Despite the results reported in earlier clinical trials

for PV-10 and PH-10, we do not know whether any clinical trials we may conduct will demonstrate adequate efficacy and safety to

result in regulatory approval to market our product candidates. If later stage clinical trials do not produce favorable results,

our ability to obtain regulatory approval for our product candidates, may be adversely impacted.

Delays

in clinical trials are common and have many causes, and any delay could result in increased costs to us and jeopardize or delay

our ability to obtain regulatory approval.

Our

planned or ongoing clinical trials may not begin on time, have an effective design, enroll a sufficient number of subjects, or

be completed on schedule, if at all. Events which may result in delays or unsuccessful completion of clinical trials, including

our future clinical trials, include inability to raise funding, initiate or continue a trial, delays in obtaining regulatory approval

to commence a trial, delays in reaching agreement with the FDA or other regulatory authorities on final trial design, imposition

of a clinical hold following an inspection of our clinical trial operations or trial sites by the FDA or other regulatory authorities,

delays in reaching agreement on acceptable terms with prospective contract research organizations (“CROs”) and clinical

trial sites, delays in obtaining required institutional review board (“IRB”) approval at each site, delays in recruiting

suitable patients to participate in a trial, delays in having subjects complete participation in a trial or return for post-treatment

follow-up, delays caused by subjects dropping out of a trial, delays caused by clinical sites dropping out of a trial, time required

to add new clinical sites or to obtain regulatory approval and open sites in geographic regions beyond the sites initially planned,

and delays by our contract manufacturers to produce and deliver sufficient supply of clinical trial materials.

In

addition, we may experience a number of unforeseen events during clinical trials for our prescription drug candidates, including

PV-10 and PH-10, that could delay or prevent the commencement and/or completion of our clinical trials, including regulators or

institutional review boards may not authorize us or our investigators to commence a clinical trial or conduct a clinical trial

at a prospective trial site, the clinical study protocol may require one or more amendments delaying study completion, clinical

trials of our product candidates may produce negative or inconclusive results, and we may decide, or regulators may require us

to conduct additional clinical trials or abandon product development programs, the number of subjects required for clinical trials

of our product candidates may be larger than we anticipate, subjects may drop out of these clinical trials at a higher rate than

we anticipate and enrollment in these clinical trials may be significantly slower than we anticipated requiring us to expand the

geographic scope of enrollment of patients, clinical investigators or study subjects may fail to comply with clinical study protocols,

trial conduct and data analysis errors may occur, including, but not limited to, data entry and/or processing errors, our third-party

contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or

at all, we might have to suspend or terminate clinical trials of our prescription drug candidates for various reasons, including

a finding that the subjects are being exposed to unacceptable health risks, regulators or institutional review boards may require

that we or our investigators suspend or terminate clinical research for various reasons, including noncompliance with regulatory

requirements, the cost of clinical trials of our prescription drug candidates may be greater than we anticipate, the supply or

quality of our clinical trial materials or other materials necessary to conduct clinical trials of our prescription drug candidates

may be insufficient or inadequate, and our prescription drug candidates may have undesirable side effects or other unexpected

characteristics, causing us or our investigators to suspend or terminate the trials.

Moreover,

we or the FDA may suspend our clinical trials at any time if it appears we are exposing participants to unacceptable health risks

or if the FDA finds deficiencies in our submissions or the conduct of these trials. If initiation or completion of any of our

clinical trials for our product candidates, are delayed for any of the above reasons or other reasons, our development costs may

increase, the approval process could be delayed, any periods during which we may have the exclusive right to commercialize our

prescription drug candidates may be reduced and our competitors may bring drug products to market before us. Any of these events

could impair our ability to generate revenues from drug product sales and impair our ability to generate regulatory and commercialization

milestones and royalties, all of which could have a material adverse effect on our business.

The

results of our clinical trials may not support acceptable label claims concerning our prescription drug candidates.

Even

if our clinical trials are completed as planned, we cannot be certain that their results will support acceptable label claims

concerning our drug product candidates. Success in pre-clinical testing and early clinical trials does not ensure that later clinical

trials will be successful, and we cannot be sure that the results of later clinical trials will replicate the results of prior

clinical trials and pre-clinical testing. The clinical trial process may fail to demonstrate that our prescription drug candidates

are safe for humans or effective for indicated uses.

This

failure could cause us to abandon a prescription drug candidate and may delay development of other prescription drug candidates.

Any delay in, or termination of, our clinical trials will delay our ability to commercialize our prescription drug candidates

and generate product revenues. In addition, we anticipate that our clinical trials will involve only a small patient population.

Accordingly, the results of such trials may not be indicative of future results over a larger patient population.

Physicians

and patients may not accept and use our prescription drug candidates.

Even

if the FDA approves our drug product candidates, physicians and patients may not accept and use them. Acceptance and use of our

drug products will depend upon a number of factors including perceptions by members of the healthcare community, including physicians,

about the safety and effectiveness of our drug products, availability of reimbursement for our drug products from government or

other healthcare payers, and effectiveness of marketing and distribution efforts by us and our licensees and distributors, if

any.

Because

we expect sales or licensure of our prescription drug candidates, if approved, to generate substantially all of our revenues for

the foreseeable future, the failure of any of these drugs to find market acceptance would harm our business and could require

us to seek additional financing.

We

have no sales, marketing or distribution capabilities for our prescription drug candidates.

We

currently have no sales, marketing or distribution capabilities. Our future success depends, in part, on our ability to enter

into and maintain collaborative relationships, the collaborator’s strategic interest in the prescription drug products under

development and such collaborator’s ability to successfully market and sell any such drug products. There can be no assurance

that we will be able to establish or maintain relationships with third party collaborators or develop in-house sales and distribution

capabilities. To the extent that we depend on third parties for marketing and distribution, any revenues we receive will depend

upon the efforts of such third parties, and there can be no assurance that such efforts will be successful. In addition, there

can also be no assurance that we will be able to market and sell our prescription drug candidates in the U.S. or internationally.

Competition

in the prescription pharmaceutical and biotechnology industries is intense.

Other

pharmaceutical and biotechnology companies and research organizations currently engage in or have in the past engaged in research

efforts related to treatment of cancer and dermatological conditions, which may compete with our clinical trials for patients

and investigator resources, cause lower enrollment than anticipated, and could lead to the development of drug products or treatment

therapies that could compete directly with our drug product candidates that we are seeking to develop and market.

Many

companies are also developing novel therapies to treat cancer and dermatological conditions and, in this regard, are our competitors.

Many of the pharmaceutical companies developing and marketing these competing products have greater financial resources and expertise

than we do in research and development, manufacturing, preclinical and clinical testing, obtaining regulatory approvals, and marketing.

Smaller

companies may also prove to be competitors, particularly through collaborative arrangements with larger and more established companies

that may compete with our efforts to establish similar collaborative arrangements. Academic institutions, government agencies,

and other public and private research organizations may also conduct research, seek patent protection, and establish collaborative

arrangements for research, clinical development, and marketing of prescription drug candidates similar to ours. These companies

and institutions compete with us in recruiting and retaining qualified scientific and management personnel as well as in acquiring

technologies complementary to our drug development programs.

In

addition to the above factors, we expect to face competition in product efficacy and safety, the timing and scope of regulatory

consents, availability of resources, reimbursement coverage, price, and patent position, including potentially dominant patent

positions of others.

Since

our prescription drug candidates PV-10 and PH-10 have not yet been approved by the FDA or introduced to the marketplace, we cannot

estimate what competition these prescription drug candidates might face when they are finally introduced, if at all. We cannot

assure you that these prescription drug candidates will not face significant competition for other approved drug products, investigational

drug products, and generic equivalents.
