"We are very pleased with our performance in 2020 and believe we are well positioned for 2021 and beyond. Despite headwinds from the COVID-19 pandemic, we made significant progress executing our strategy to build shareholder value by applying our proprietary ADAPTIR and ADAPTIR-FLEX platforms to develop novel antibody-based immunotherapies for the treatment of cancer and other diseases. Notably, we announced that two patients in cohort 6 of our APVO436 Phase 1a clinical trial achieved complete remission. While the first patient in cohort 6 is no longer in a complete remission status, that patient is continuing therapy, and the second patient progressed and discontinued therapy," said Marvin L. White, President and Chief Executive Officer. "These responses indicate that we are now in a critical phase of the study, within the therapeutic range, and we look forward to advancing to the endpoint for Phase 1a. With these promising results, we are just beginning to demonstrate the power and potential of our proprietary platform technologies to help extend and save patients’ lives."

"We also made significant progress strengthening our financial position by selling the RUXIENCE royalty payment stream and amending our non-dilutive term loan from MidCap Financial, providing additional capital cushion to fund our promising clinical programs and operations. 2021 will be another important year for Aptevo as we continue to advance APVO436 in the clinic. With a stronger balance sheet, we are optimistic about the prospects for Aptevo and our ADAPTIR and ADAPTIR-FLEX candidates," concluded Mr. White.

Clinical Update

Aptevo has multiple candidates moving towards clinical development, and its ADAPTIR and ADAPTIR-FLEX technology platforms are uniquely positioned to develop and advance its studies.

To date, enrollment in the APVO436 trial cohorts 1 through 9 has been completed and enrollment in cohort 10 is ongoing. The Company has observed, as signs of clinical activity, stabilization of leukemia, a response that consequently deepened to partial remission and complete remission (CR) in two difficult to treat relapsed/refractory AML patients. Most patients have either completed their dose regimens or have discontinued dosing without a dose-limiting toxicity.

Additionally, Aptevo and Alligator Bioscience plan to file a clinical trial application (CTA) in Europe in 2021 and to subsequently commence first in human dosing in the fourth quarter of 2021.

Sale of RUXIENCE Royalty Payments to HealthCare Royalty Management; Amendment to Non-Dilutive Term Loan Agreement with MidCap Financial

On March 30, 2021, the Company entered into and closed a royalty purchase agreement (the "Royalty Purchase Agreement") with an entity managed by HealthCare Royalty Management, LLC ("HCR") pursuant to which the Company sold to HCR the right to receive all royalty payments made by Pfizer Inc. ("Pfizer") in respect of net sales of RUXIENCE. Under the terms of the Royalty Purchase Agreement, the Company received $35 million (the "Investment Amount") at closing and the Company is eligible to receive additional payments in aggregate of up to an additional $32.5 million based on the achievement of sales milestones in 2021, 2022, and 2023 (collectively, the "Milestone Amounts"). The Royalty Purchase Agreement further provides that, once HCR reaches aggregate royalty payments totaling 190% of the Investment Amount plus the Milestone Amounts to the extent paid by HCR to the Company, Aptevo will be entitled to receive 50% of any additional royalty payments by Pfizer thereafter. Piper Sandler acted as exclusive Financial Advisor to the Company for this transaction. Morgan Lewis acted as legal counsel to Aptevo.

In connection with the Royalty Purchase Agreement, the Company amended its term loan agreement with MidCap Financial and used $10 million of the proceeds received from the Royalty Purchase Agreement with HCR to pay down outstanding principal. $10 million of the remaining $15 million principal balance will be payable on March 31, 2022.

After receipt of the Investment Amount from HCR and the $10 million prepayment of the Credit Agreement to MidCap Financial, the Company’s cash runway is extended into Q2 2022. If earned, the $32.5 million potential future Milestone Amounts will provide additional non-dilutive funding to the Company.

Response to Indication of Interest from Tang Capital Partners

The Aptevo Board was open to exploring the indication of interest from TCP and made earnest efforts to evaluate it. However, it was unable to do so because it was unable to reach agreement with TCP on the terms of a customary non-disclosure agreement, including limitations on the use of confidential information by TCP. Had agreement on the terms of a non-disclosure agreement been reached, it would have permitted the exchange of confidential information and would have enabled both parties to conduct due diligence. In this early stage of the Company’s development, the Aptevo Board believes it is difficult for the market to accurately value the potential of Aptevo’s proprietary platform technologies and therapeutic candidates, which have just begun to demonstrate their effectiveness and potentially life-saving capabilities to the Company’s patients, shareholders and other stakeholders. The Board will continue to carefully evaluate any indications of interest and proposals for strategic transactions that it receives from current shareholders or otherwise, in line with its fiduciary duties and commitment to acting in the best interests of all of the Company’s shareholders.

2020 Highlights

Continued enrollment in APVO436 clinical trial, a Phase 1/1b dose escalation, open-label study evaluating the safety and pharmacokinetic profile of APVO436, a novel anti-CD123 x anti-CD3 targeted investigational bispecific antibody therapy being evaluated for the treatment of acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). Dosing in Cohorts 1 through 9 is complete and enrollment in Cohort 10 has commenced.
Launched Aptevo’s second platform technology ADAPTIR-FLEX and introduced a new bispecific prostate cancer candidate APVO442 built on the ADAPTIR-FLEX platform. APVO442 is a unique T-cell engager targeting PSMA and CD3 for the treatment of prostate cancer, and Aptevo is optimistic about the potential outcomes for patients impacted by these tumors.
Agreed with our partner, Alligator Bioscience, to advance the bispecific 4-1BBx5T4 antibody ALG.APV-527 into Phase 1 Clinical Development.
APVO436 included in the Leukemia & Lymphoma Society’s Beat AML Master Clinical Trial; APVO436 being evaluated for frontline treatment in patients newly diagnosed with AML.
Sold worldwide rights to IXINITY to Medexus Pharmaceuticals, Inc. ("Medexus") for an upfront payment to Aptevo of $30 million; potential milestone payments totaling up to $11 million; and the opportunity to receive significant deferred payments ("royalties") on future U.S. and Canadian net sales of IXINITY. Royalties are earned at the rate of 2% of net revenue through the earlier of June 2022 or completion of the IXINITY pediatric trial being run by Medexus. After that, the royalty rate will increase to 5%.
Fully repaid Aptevo’s $20 million term debt facility with MidCap Financial in February 2020 and received additional non-dilutive funding through a $25 million term loan agreement with MidCap Financial on August 5, 2020.
Recorded $4.3 million of RUXIENCE royalty payments from Pfizer related to global sales of the product for the year ended December 31, 2020.
2020 Summary Financial Results

Cash Position: Aptevo had cash, cash equivalents, and short-term investments as of December 31, 2020 totaling $42.5 million, including restricted cash of $2.6 million. The restricted cash will release, in Aptevo’s favor, over the next twelve months.

Royalty Revenue: Royalty revenue increased by $4.3 million for the year ended December 31, 2020. The increase is related to a 2.5% royalty we are entitled to receive from Pfizer related to sales of RUXIENCE, a biosimilar to the drug RITUXAN, which was approved by the FDA in July 2019 and launched by Pfizer in early 2020. RUXIENCE is a trademark of Pfizer; RITUXAN is a trademark of Biogen.

Research and Development Expenses: Research and development expenses decreased by $6.9 million, to $17.9 million for the year ended December 31, 2020 from $24.8 million for the year ended December 31, 2019. Expenses decreased primarily related to decreased spending on programs discontinued in 2019. Additionally, pre-clinical program, general research and discovery costs decreased primarily due to decreased spending on outside testing and manufacturing for ALG.APV-527.

General and Administrative Expenses: For the year ended December 31, 2020, general and administrative expenses decreased by $2.2 million, or 14%, to $14.0 million from $16.2 million for December 31, 2019. This decrease was primarily due to reduced personnel and professional services costs.

Other Expense: Other expense consists primarily of gains or losses realized on foreign currency revaluation, costs related to debt extinguishment, accrued exit fees on debt, and interest on debt. Other expense was $3.4 million for the year ended December 31, 2020 and $2.1 million for the year ended December 31, 2019. This increase is primarily due to a loss on extinguishment of debt of $2.1 million, which consists of interest, exit, prepayment, and legal fees recognized during the first quarter of 2020.

Discontinued Operations: Income from discontinued operations was $13.2 million for the year ended December 31, 2020 and $2.6 million for the year ended December 31, 2019. The financial statements for these periods include discontinued operations from two separate transactions: the sale of Aptevo’s hyperimmune business in 2017, from which milestone payments were recognized in 2019, and the sale in February 2020 of the Aptevo BioTherapeutics LLC business.

Medexus reported their net IXINITY sales to Aptevo and made a deferred payment to Aptevo of $0.4 million for the first three quarters of 2020. As such, we recorded the deferred payment amount related to Medexus’ sales of IXINITY as a gain when collected. Subsequent to year end, Medexus made a deferred payment of approximately $0.2 million, related to fourth quarter 2020 IXINITY sales.

Net Loss: Aptevo’s net loss for the year ended December 31, 2020 was $17.8 million or $5.23 per share, compared to a net loss of $40.4 million or $13.86 per share for the corresponding period in 2019.

Provectus Biopharmaceuticals Announces Publication of Australian Compassionate Use Patients Treated with PV-10® Immunotherapy for In-Transit Melanoma Lesions

On March 31, 2021 Provectus (OTCQB: PVCT) reported that Melanoma Research had published results from an investigator-led, single-center study of Australian in-transit melanoma (ITM) patients who received intralesional (aka intratumoral) PV-10 under a Provectus-sponsored expanded access (aka compassionate use) program (EAP) (Press release, Provectus Biopharmaceuticals, MAR 31, 2021, View Source [SID1234577446]).

The Melanoma Research article, entitled "Treatment of in-transit melanoma metastases using intralesional PV-10," detailed the experience of investigators at Melanoma Institute Australia (MIA; formerly the Sydney Melanoma Unit) in Sydney, Australia who treated 48 patients from 2008 to 2016.

The article may be accessed at: View Source (subscription required).

Key highlights of the Melanoma Research publication:

Baseline characteristics: 58% women; median age of 75.1 years (range 21.5-93.5),
Median of 5 lesions treated with PV-10 (interquartile range [IQR] 2-7),
Median of 1 PV-10 treatment (IQR 1-2),
46% complete response (CR) and 86% overall response rate (ORR) in patients, and
12- and 24-month overall survival (OS) rates of 77% and 56%, respectively.
This is the third publication about single-agent PV-10 treatment of ITM lesions under Provectus’ EAP (which has treated about 200 patients to date) and the fifth publication overall. Previous publications describing EAPs led by other major Australian medical institutions and the Company’s Phase 1 and 2 clinical trials at Australian and U.S. sites include:

"Intralesional PV-10 for the treatment of in-transit melanoma metastases – Results of a prospective, non-randomized, single center study" (Read et al. J Surg Oncol 2018), which describes the EAP at Princess Alexandra Hospital in Brisbane: 45 patients treated from 2008 to 2015; 42% patient CR (86% ORR); median of 1 PV-10 treatment (range 1-4),

"Intralesional PV-10 for in-transit melanoma – A single-center experience" (Lippey et al. J Surg Oncol 2016; subscription required), which describes the EAP at Peter MacCallum Cancer Centre in Melbourne: 19 patients treated from 2010 to 2014; 26% patient CR (52% ORR); most patients received 1 PV-10 treatment,

"Phase 2 Study of Intralesional PV-10 in Refractory Metastatic Melanoma" (Thompson et al. Ann Surg Oncol 2015): 28 (out of 80) patients with all known lesions treated; median of 1 PV-10 treatment (range 1-4); 50% patient CR (71% ORR), and

"Chemoablation of metastatic melanoma using intralesional Rose Bengal" (Thompson et al. Mel Res 2008; subscription required): 11 (out of 20) patients treated in the Phase 1 trial; 1 PV-10 treatment; 27% patient CR (54% ORR).
Dominic Rodrigues, Vice Chair of the Company’s Board of Directors, said, "Patients who present with in-transit melanoma lesions suffer from a rare disease that is a serious, life-threatening condition with no approved therapies. No drug therapies provide the rapid, sustained reduction of tumor burden, with low toxicity, that investigational drug product PV-10 does. Injection of lesions with PV-10 is globally recognized as a treatment option for in-transit melanoma patients in clinical practice guidelines, including those for Australiaa, Canadab, Europec, and the U.S.d"

Mr. Rodrigues added "Given the high percentage of in-transit melanoma lesions that achieve complete response from typically one or two PV-10 injections, and its established safety profile, we believe there is a role for PV-10 in the treatment of in-transit melanoma lesions for those patients who are not candidates for systemic drug therapies."

About PV-10

Intralesional (IL) administration of PV-10 for the treatment of solid tumor cancers can yield immunogenic cell death within hours of tumor injection, and induce tumor-specific reactivity in circulating T cells within days.1,2,3 This IL PV-10-induced functional T cell response may be enhanced and boosted in combination with immune checkpoint blockade (CB).4 In CB-refractory advanced cutaneous melanoma, IL PV-10 may restore disease-specific T cell function, which may also be prognostic of clinical response. IL PV-10 has been administered to over 450 patients with cancers of the skin and of the liver. It is administered under visual, tactile or ultrasound guidance to superficial malignancies, and under CT or ultrasound guidance to tumors of the liver.

About Rose Bengal Disodium

RBD is 4,5,6,7-tetrachloro-2′,4′,5′,7′-tetraiodofluorescein disodium, a halogenated xanthene and Provectus’ proprietary lead molecule. Provectus’ current Good Manufacturing Practices (cGMP) RBD is a proprietary pharmaceutical-grade drug substance produced by the Company’s quality-by-design (QbD) manufacturing process to exacting regulatory standards that avoids the formation of uncontrolled impurities currently present in commercial-grade rose bengal. Provectus’ RBD and cGMP RBD manufacturing process are protected by composition of matter and manufacturing patents as well as trade secrets.

An IL formulation (i.e., by direct injection) of cGMP RBD drug substance, cGMP PV-10, is being developed as an autolytic immunotherapy drug product for solid tumor cancers.

IL PV-10 is also undergoing preclinical study for relapsed and refractory pediatric solid tumor cancers, such as neuroblastoma, Ewing sarcoma, rhabdomyosarcoma, and osteosarcoma.5,6

A topical formulation of cGMP RBD drug substance, PH-10, is being developed as a clinical-stage immuno-dermatology drug product for inflammatory dermatoses, such as atopic dermatitis and psoriasis. RBD can modulate multiple interleukin and interferon pathways and key cytokine disease drivers.7

Oral formulations of cGMP RBD are undergoing preclinical study for relapsed and refractory pediatric blood cancers, such as acute lymphocytic leukemia and acute myelomonocytic leukemia.8,9

Oral formulations of cGMP RBD are also undergoing preclinical study as prophylactic and therapeutic treatments for high-risk adult solid tumor cancers, such as head and neck, breast, pancreatic, liver, and colorectal cancers.

Different formulations of cGMP RBD are also undergoing preclinical study as potential treatments for multi-drug resistant (MDR) bacteria, such as Gram-negative bacteria.

Topical formulations of cGMP RBD are also undergoing preclinical study as potential treatments for diseases of the eye, such as infectious keratitis

Tumor Cell Lysosomes as the Seminal Cancer Drug Target

Lysosomes are the central organelles for intracellular degradation of biological materials, and nearly all types of eukaryotic cells have them. Discovered by Christian de Duve, MD in 1955, lysosomes are linked to several biological processes, including cell death and immune response. In 1959, de Duve described them as ‘suicide bags’ because their rupture causes cell death and tissue autolysis. He was awarded the Nobel Prize in 1974 for discovering and characterizing lysosomes, which are also linked to each of the three primary cell death pathways: apoptosis, autophagy, and necrosis.

Building on the Discovery, Exploration, and Characterization of Lysosomes

Cancer cells, particularly advanced cancer cells, are very dependent on effective lysosomal functioning.10 Cancer progression and metastasis are associated with lysosomal compartment changes11,12, which are closely correlated (among other things) with invasive growth, angiogenesis, and drug resistance13.

RBD selectively accumulates in the lysosomes of cancer cells upon contact, disrupting the lysosomes and causing the cells to die. Provectus2,14, external collaborators5, and other researchers15,16,17 have independently shown that RBD triggers each of the three primary cell death pathways: apoptosis, autophagy, and necrosis.

Cancer Cell Autolytic Death via RBD: RBD-induced autolytic cell death, or death by self-digestion, in Hepa1-6 murine hepatocellular carcinoma (HCC) cells can be viewed in this Provectus video of the process (ethidium homodimer 1 [ED-1] stains DNA, but is excluded from intact nuclei; lysosensor green [LSG] stains intact lysosomes; the video is provided in 30-second frames, with a duration of approximately one hour). Exposure to RBD triggers the disruption of lysosomes, followed by nucleus failure and autolytic cell death. Identical responses have been shown by the Company in HTB-133 human breast carcinoma (which can be viewed in this Provectus video of the process, with a duration of approximately two hours) and H69Ar human multidrug-resistant small cell lung carcinoma. Cancer cell autolytic cell death was reproduced by research collaborators in neuroblastoma cells to show that lysosomes are disrupted upon exposure to RBD.5

Tumor Autolytic Death via RBD: RBD causes acute autolytic destruction of injected tumors (via autolytic cell death), mediating the release of danger-associated molecular pattern molecules (DAMPs) and tumor antigens; release of these signaling factors may initiate an immunologic cascade where local response by the innate immune system may facilitate systemic anti-tumor immunity by the adaptive immune system. The DAMP release-mediated adaptive immune response activates lymphocytes, including CD8+ T cells, CD4+ T cells, and NKT cells, based on clinical and preclinical experience in multiple tumor types. Mediated immune signaling pathways may include an effect on STING, which plays an important role in innate immunity.9

Orphan Drug Designations (ODDs)

ODD status has been granted to RBD by the U.S. Food and Drug Administration for metastatic melanoma in 2006, hepatocellular carcinoma in 2011, neuroblastoma in 2018, and ocular melanoma (including uveal melanoma) in 2019.

Intellectual Property

Provectus’ IP includes a family of US and international (a number of countries in Asia, Europe, and North America) patents that protect the process by which cGMP RBD and related halogenated xanthenes are produced, avoiding the formation of previously unknown impurities that exist in commercial-grade rose bengal in uncontrolled amounts. The requirement to control these impurities is in accordance with International Council on Harmonisation (ICH) guidelines for the manufacturing of an injectable pharmaceutical. US patent numbers are 8,530,675, 9,273,022, and 9,422,260, with expirations ranging from 2030 to 2031.

The Company’s IP also includes a family of US and international (a number of countries in Asia, Europe, and North America) patents that protect the combination of RBD and CB (e.g., anti-CTLA-4, anti-PD-1, and anti-PD-L1 agents) for the treatment of a range of solid tumor cancers. US patent numbers are 9,107,887, 9,808,524, 9,839,688, and 10,471,144, with expirations ranging from 2032 to 2035; US patent application numbers include 20200138942 (i.e., 16/678,133), which has been allowed.

PVSRIPO is a novel viral immunotherapy that activates the innate and adaptive immune system to stimulate the production of a functional, systemic anticancer CD8+ T cell response. Following positive phase 1 results,1 the phase 2 trial will further explore PVSRIPO’s impact on this population of patients in severe need of additional therapeutic options.

"Anti-PD-1/L1 therapies have been a major advancement in melanoma treatment, however, many patients develop resistance or never respond in the first place," said Matt Stober, President and Chief Executive Officer at Istari Oncology. "We are very optimistic about the prospects for the phase 2 trial. PVSRIPO monotherapy has already shown clinical activity in this population, and its mechanism is synergistic with anti-PD-1/L1 therapies, so we believe the combination may provide even more benefit."

"As the use of anti-PD-1/L1 therapies has grown, so too has the need for new treatments as patients experience primary or acquired resistance and must resort to therapeutic approaches with a high incidence of serious adverse events," said Garrett Nichols, MD, MS, Chief Medical Officer at Istari Oncology. "Our goal is to address this unmet need, and LUMINOS-102 will be a critical step in determining whether PVSRIPO can rekindle antitumor responses in the PD-1/L1 refractory population without adding any significant toxicity."

LUMINOS-102 is an open-label, phase 2, multicenter randomized trial (NCT04577807) in patients with melanoma that have progressed on anti–PD1/L1 therapy and will characterize the safety, tolerability and initial efficacy of PVSRIPO intratumoral injection alone (Arm 1) and in combination with a PD-1 inhibitor (Arm 2). An interim analysis is planned once 20 patients have been randomized and treated for 3 months. Patient outcomes, including objective response rates (by RECIST criteria), durability of responses, progression free survival and overall survival will be measured over a 24-month time frame.

LUMINOS-102 builds upon a successful phase 1 study of PVSRIPO monotherapy in anti–PD-1 refractory advanced melanoma presented by Dr. Georgia Beasley and colleagues at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) 2020 Annual Meeting and in-press for an upcoming issue of the Journal for ImmunoTherapy of Cancer (JITC). In the phase 1 study, the overall response rate in subjects who received three single intratumoral injections 3 weeks apart (the maximum number administered in the study) was 67% (4/6), suggesting PVSRIPO was able to initiate or rekindle responses in patients who have failed anti–PD-1 therapy. Responses were observed in both injected and noninjected tumors, suggestive of an abscopal response. No serious adverse events or dose-limiting toxicities were observed.

"Being based on the poliovirus vaccine, our team was intrigued by the potential for PVSRIPO to leverage an immunological recall response to fight cancer in patients who have been vaccinated against polio. This and other unique mechanisms as well as the responses seen in the phase 1 trial encouraged us to get involved in LUMINOS-102," noted Ding Wang, MD, ?Director of the Phase 1 Program and Associate Director of Clinical Trials Office at Henry Ford Cancer Institute, Detroit, MI. "LUMINOS-102 will build on these data and further evaluate the ability of PVSRIPO to generate a systemic immune response, important for patients with unresectable anti–PD-1 refractory melanoma. We’re proud to be the first site to treat a participant and looking forward to continuing enrollment."

The LUMINOS-102 phase 2 trial will be conducted across more than 20 research sites across the US including Henry Ford Cancer Institute.

About PVSRIPO
PVSRIPO is an investigational immunotherapy based on the live attenuated Sabin type 1 poliovirus vaccine that has been genetically modified for safety. PVSRIPO has a distinct target (the poliovirus receptor, CD155), which is expressed on virtually all solid tumors and antigen-presenting cells. Via CD155, PVSRIPO targets tumors with two primary mechanisms: 1) direct damage to and killing of cancerous cells; and 2) engaging innate and adaptive antitumor immune responses via nonlethal infection of antigen presenting cells in the tumor, which stimulates a specific signaling pathway resulting in a sustained, robust type-I/III interferon-dominant response, with minimal release of unwanted cytokines. Its effects are potentiated by prior vaccination against poliovirus. PVSRIPO has been granted Breakthrough Therapy Designation and Orphan Status by the FDA in recurrent glioblastoma. PVSRIPO has also been granted Orphan Status by the FDA for advanced melanoma.

About Melanoma
There are estimated to be over 12,000 new and recurrent cases of advanced, unresectable melanoma diagnosed in the U.S. each year, and around 7,000 deaths. While immune checkpoint inhibitors have dramatically improved the outlook for advanced melanoma patients today, most patients treated with these immunotherapies are either primary nonresponders or eventually develop immune-refractory progressive disease and require additional therapy.

Galectin Therapeutics Reports Fiscal 2020 Financial Results and Provides Business Update

Joel Lewis, Chief Executive Officer and President of Galectin Therapeutics, said, "I am very encouraged by the progress achieved in fiscal 2020, and remain extremely optimistic for 2021. Given the current challenging environment, I am proud of our success, highlighted by site activations and ongoing enrollment of our innovative NAVIGATE study. This global program continues to be the only active late-stage trial of patients with compensated NASH cirrhosis, where the medical need is greatest and with a clinically meaningful endpoint. Our concurrent hepatic impairment study will also provide important information on belapectin tolerance, safety and exposure in advanced cirrhotic patients.

Over the course of the last year at the Board’s direction we have taken aggressive steps to strengthen our organization, adding Pol Boudes as Chief Medical Officer, as well as Mr. Richard Zordani and Dr. Elissa Schwartz to our Board of Directors. These changes informed my decision to accept the role of Chief Executive Officer, and they afforded me the confidence to receive 80% of my compensation in the

form of Galectin stock. Additionally, I believe this breadth of talent reinvigorated Galectin and placed the Company in a position to monetize our assets. This has served to strengthen my commitment to my compensation strategy, which aligns my interests with all shareholders.

More recently, the peer-reviewed publication of a well-recognized mouse model has shown that the combination of belapectin, a galectin-3 inhibitor, with immunotherapy reprograms the tumor microenvironment. This favors anti-tumor immunity, results in better anti-tumor activity, and most importantly, brings further rationale for our ongoing cancer trial combining belapectin with Keytruda, a potent PD-1 inhibitor. Providence Cancer Institute is currently conducting the study and preliminary results suggest improved activity and, potentially, improved tolerance of this regimen.

I am extremely confident in our science, our team, and our progress," concluded Lewis. The upcoming year will be dedicated to advancing our trial in NASH cirrhosis and supporting investigations of belapectin’s safety and efficacy in other indications, such as the ongoing cancer trial in conjunction with the Providence Cancer Institute. I also want to recognize the outstanding efforts of our entire team, who persevered through the challenges precipitated by COVID-19 in the interest of developing a therapy for NASH cirrhosis, a critical, unmet medical need. Let me once again thank the investigators and patients participating in our NAVIGATE trial, where a positive outcome would be very clinically relevant for patients with NASH cirrhosis."

Richard E. Uihlein, Chairman of the Board, added, "I want to echo Joel’s sentiment and thank Pol, Jack and our entire team for their dedication throughout

this past year, especially their commitment to initiating our exciting NAVIGATE trial under less than optimal circumstances due to the global pandemic. Joel has proven to be the leader we all expected, and I am pleased with the progress he has achieved since assuming the role and confident in his ability to unlock the value of our proprietary compound, belapectin. Peer-reviewed research, such as that recently published in OncoImmunology, clearly confirms our basic scientific premise regarding belapectin’s anti-inflammatory characteristics in a broad range of fibrosis as well as its ability to potentially enhance the efficacy of cancer therapies. As such, the NAVIGATE trial represents an opportunity to further demonstrate the anti-inflammatory activity of belapectin, which would open up vast new opportunities to investigate other indications and establish our compound as a foundation for a platform technology."

NAVIGATE Trial Update

The NAVIGATE trial uses a seamless, adaptive design to confirm dose selection and reaffirm the observed efficacy of belapectin to prevent the development of esophageal varices in the NASH-CX trial. Pre-planned adaptations will inform the larger Phase 3 trial component.

Key clinical study milestones:

First patient randomized August 2020

130+ sites, 12 countries in North America, Europe, Asia and Australia

Phase 2b part to Interim Analysis will be ~315 patients

Recruiting period for phase 2b portion now expected to conclude around the end of 2021 due to COVID-19 impact on recruitment

Key inclusion criteria – NASH cirrhosis (baseline or historical liver biopsy), clinical sign of portal hypertension, no esophageal varices (esophago-gastro endoscopy)

Interim analysis expected late 2023

Peer-reviewed publication, Scientific Presentations and Conferences

OncoImmunology published a peer-reviewed article describing how belapectin, a potent galectin-3 inhibitor, in combination with an anti-OX40 (CD134) monoclonal antibody, reduces tumor progression compared to either agent alone. The paper, titled "Galectin-3 inhibition with belapectin combined with anti-OX40 therapy reprograms the tumor microenvironment to favor anti-tumor immunity," describes results from a collaboration between Galectin Therapeutics and Providence Cancer Institute highlighting the mechanism of action of the combination which is explained by a reduction in myeloid-derived suppressor cell infiltration and function coupled to an increase in T-cell effector function. For many years, galectin-3 has been known to play a key role in the control of tumor-induced immunosuppression. Galectin-3 acts to maintain tumor growth, in part, by supporting the generation of suppressive macrophages and inhibiting T cell function. This creates an attractive rationale for the use of a galectin-3 inhibitor, such as belapectin, to improve anti-tumor activities of multiple cancer therapies.

Financial Results

For the year ended December 31, 2020, the Company reported a net loss applicable to common stockholders of $23.6 million, or ($0.41) per share, compared to a net loss applicable to common stockholders of $20.2 million, or ($0.39) per share for the full year 2019. The increase is largely due to an increase in research and development expenses related to our NAVIGATE clinical trial, partially offset by a non-cash, one-time warrant modification charge of $6.6 million in 2019.

Research and development expense for 2020 was $18.0 million compared with $7.5 million for 2019. The increase was primarily due to costs related to our NAVIGATE clinical trial, along with preparations and some preclinical activities incurred in support of the clinical program, such as development and reproductive toxicity studies, clinical supplies and other supportive activities. General and administrative expenses for 2020 were $5.5 million, down from $6.0 million for the full year 2019, primarily due to decreases in legal, investor relations and non-cash stock-based compensation expenses partially offset by an increase in insurance expenses.

As of December 31, 2020, the Company had $27.1 million of cash and cash equivalents. The Company also has a $10 million unsecured line of credit, under which no borrowings have been made to date. The Company believes it has sufficient cash, including availability under the line of credit, to fund currently planned operations and research and development activities through at least March 31, 2022.

The Company expects that it will require more cash to fund operations after March 31, 2022, and believes it will be able to obtain additional financing as needed. The currently planned operations include costs related to our adaptively designed NAVIGATE Phase 2b/3 clinical trial. Currently, we expect to require an additional approximately $45-$50 million to cover costs of the trial to reach the planned interim analysis estimated to occur in the second half of 2023 along with drug manufacturing and other scientific support activities and general and administrative costs and further amounts to complete the Phase 3 portion of the trial. However, there can be no assurance that we will be successful in obtaining such new financing or, if available, that such financing will be on terms favorable to us.
