"While the COVID-19 pandemic has presented unexpected challenges, we continue to execute on our pipeline and business strategy, and we look forward to further progress throughout 2020," said John Orwin, Chief Executive Officer. "Patients continue to be enrolled and treated in our Phase 1b dose-escalation clinical trial evaluating ATRC-101 in multiple solid tumors. In addition, we believe our recently announced alliance with BeiGene and IGM Biosciences to help address the COVID-19 pandemic underscores the potential of our differentiated discovery platform, and we are working closely with our partners to advance research and development as quickly as possible."

Recent Developments and Highlights

In February 2020, Atreca commenced patient dosing in a Phase 1b first-in-human clinical trial evaluating ATRC-101 in patients with select solid tumor cancers. Patient screening continues in the study and, to date, three subjects have been enrolled in the first dose cohort. The ongoing COVID-19 pandemic is likely to impact our ability to initiate additional clinical trial sites quickly, which may ultimately result in enrollment delays.

Atreca announced a collaboration with BeiGene, Ltd. and IGM Biosciences, Inc. to discover and develop a novel antibody treatment for COVID-19. The alliance will utilize Atreca’s proprietary discovery platform to generate the sequences of antibodies made by particular B cells found in blood obtained from acutely infected COVID-19 patients.
Upcoming Milestone

Atreca will present a trial-in-progress poster at the upcoming American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2020 Virtual Scientific Program being held from May 29 to May 31, 2020. The poster will describe the design of Atreca’s ongoing Phase 1b first-in-human clinical trial evaluating ATRC-101 in patients with select solid tumor cancers.

"Continued execution on our strategic priorities in our second fiscal quarter resulted in an expansion of our linear DNA story to include COVID-19 vaccine candidate and diagnostic kit programs and the addition of new development customers. These new development customers, several of which are leaders in the field of gene and redirected-cell therapies, demonstrate broadening interest and adoption of our proprietary linear DNA approach to preclinical biotherapeutics and diagnostics development and further validate linear DNA as a viable alternative for plasmid DNA," stated Dr. James A. Hayward, president and CEO of Applied DNA.

"Most of our activities during the quarter were devoted to our COVID-19 development programs that serve to also elevate the profile of our PCR-based LinearDNA platform to the biopharma industry as a powerful, large-scale tool for the rapid manufacture of DNA-based therapeutics," continued Dr. Hayward. "The global focus on the pandemic and the speed with which vaccine candidates are being developed are laying bare the limitations of modern vaccine development that are almost-exclusively reliant on plasmid-based technologies that are often slow and require much more downstream processing. Because our linear DNA approach does not require bacterial fermentation and has the added advantage of essentially no risk of contamination by genes for antibiotic resistance and other genetic contaminants, we believe our platform is well suited for such DNA-based therapeutics as engineered T cells, gene therapies, RNAi, and vaccines, such as for COVID-19 or future emerging infectious diseases. One new development customer, a global Top-20 pharmaceutical manufacturer, is evaluating the full scope of our platform to potentially serve as a foundational tool for their future genetic therapy pipeline. As the industry comes to terms with the limitations of plasmid-based technologies in terms of production speed and risk, we believe this will set the stage for a paradigm shift towards the rapid manufacturing of linear DNA vaccines with our LinearDNA platform as the accelerator."

Concluded Dr. Hayward, "Looking ahead, we remain focused on driving interest and building demand for our linear DNA approach across certain highly-regulated markets, such as drug development, that we believe offer a path to higher and more recurring revenue. Takis Biotech ("Takis") has initiated preclinical animal trials of our LinearDNA version of their vaccine candidates that we believe will demonstrate similar, robust immune responses to their plasmid-based constructs, but with the added advantage of speed and scalability to manufacture for global use. Concurrently, we are preparing for the possibility for Takis to progress to human trials this fall by readying our facility for compliance with the FDA’s cGMP regulations that govern the quality of biologics for human use. We have also developed our Linea COVID-19 high-throughput and high-sensitivity SARS-CoV-2 detection kit to enable mass-testing that can be a crucial tool in the toolbox of health systems and governments in the fight to further ‘flatten the curve’. Having received Emergency Use Authorization from the FDA today, we are now focused on the commercialization of our kit to assist frontline workers leading the charge against the pandemic. Pharmaceutical molecular tagging is another target market and one where the FDA has granted us entry into its Emerging Technology Program that gives us a path to drive the industry’s adoption of our authentication technologies and mitigate participation of counterfeit and adulterated drugs in the legitimate pharmaceutical supply chain. We will continue to build our business development pipeline and execute on our strategy to advance and prove the capabilities of linear DNA to drug developers and the broader pharmaceutical industry."

Fiscal Second Quarter 2020 Financial Results:

·Revenues decreased 29% for the second quarter of fiscal 2020 to $552 thousand, compared with $778 thousand reported in the same period of the prior fiscal year and decreased 13% from $634 for the first quarter of fiscal 2020. This decrease in revenues year over year is due to a decrease of $305 thousand in service revenues, offset by an increase of $79 thousand in product revenues. The decrease in service revenues is primarily attributable to a decrease from a government contract award that ended during the second half of fiscal 2019 and a decline in precommercial feasibility projects in both textiles and cannabis. The increase in product revenues was primarily related to an increase in biopharmaceutical revenues during the quarter ended March 31, 2020.

·Total operating expenses decreased to $3.1 million for the second fiscal quarter of 2020, compared with $3.3 million in the prior fiscal year’s second quarter. This decrease is attributable to a decrease in professional fees of approximately $183 thousand due to reduced legal fees. To a lesser extent, the decrease relates to a reduction of approximately $64 thousand in travel fees as result of travel restrictions associated with COVID-19. This decrease was offset by an increase in research and development expenses of $52 thousand.

·Net loss for the quarter ended March 31, 2020 was $3.0 million, or $0.79 per share, compared with a net loss of $2.7 million, or $3.22 per share, for the quarter ended March 31, 2019, an increase of 10%, and a net loss of $2.7 million, or $1.12 per share, for the quarter ended December 31, 2019.

·Excluding non-cash expenses, Adjusted EBITDA was negative $2.6 million and a negative $2.3 million for the quarters ended March 31, 2020 and 2019, respectively. See below for information regarding non-GAAP measures.

·Cash was $8.7 million at March 31, 2020 that includes the exercise of warrants associated with the November 15, 2019 underwritten public offering ("the offering") totaling approximately $2.8 million in net proceeds. Subsequent to March 31, 2020 the Company received a further $2.9 million of net proceeds through the exercise of warrants associated with the offering. There are a total of approximately 1.5 million warrants outstanding from the offering at May 14, 2020.

Six Months Ended March 31, 2020 Financial Results:

·Revenues decreased 29% for the first half of fiscal 2020 to $1.2 million, compared with $1.7 million reported in the same period of the prior fiscal year. This decrease in revenue year over year is due to a decrease of $472 thousand in service revenues and a decrease of $5 thousand in product revenues. The decrease in service revenues is primarily attributable to a decrease from a government contract award that ended during the second half of fiscal 2019.

·Total operating expenses decreased to $6.1 million for the six months ended March 31, 2020, compared with $7.2 million in the prior fiscal year’s first six months. This decrease is primarily attributable to decreases in payroll of approximately $272 thousand, attributable to headcount reductions, a decrease in stock-based compensation expense of approximately $262 thousand as well as decreases in legal and professional fees of $139 thousand, consulting fees of $121 thousand, reduced travel expenses of $110 thousand and research and development of $93 thousand.

·Net loss for the six-month period ended March 31, 2020 was $5.6 million, or $1.76 per share, compared with a net loss of $5.9 million, or $6.51 per share, for the six months ended March 31, 2019, an improvement of 5%.

·Excluding non-cash expenses, Adjusted EBITDA was negative $5.0 million and a negative $4.9 million for the six months ended March 31, 2020 and 2019, respectively. See below for information regarding non-GAAP measures.

First Quarter 2020 Highlights and Subsequent Updates:

The U.S. FDA Granted Orphan Drug Designations for ALPN-101 in the Prevention and Treatment of Acute Graft Versus Host Disease. In March, the United States Food and Drug Administration (FDA) granted two orphan drug designations for ALPN-101, our first-in-class inhibitor of the CD28 and ICOS inflammation pathways, for the prevention of, and for the treatment of, acute GVHD.
ALPN-202 Study Design Presented at AACR (Free AACR Whitepaper). In April, Alpine presented the design of NEON-1, the first-in-human study of ALPN-202, our first-in-class clinical stage conditional CD28 costimulator and dual checkpoint inhibitor, at the American Association of Cancer Research (AACR) (Free AACR Whitepaper) Virtual Annual Meeting I, in the Phase I Trials in Progress Virtual Poster Session.
ALPN-101 Preclinical Data in Inflammatory Bowel Disease (IBD) Presented at 2020 Crohn’s & Colitis Congress and Digestive Disease Week 2020. ALPN-101 modulated inflammatory cytokines in vitro from human IBD peripheral blood mononuclear cells (PBMC) more potently than CD28 or ICOS single-pathway inhibitors and significantly reduced disease activity in vivo in the CD4+CD45RBhi T cell transfer mouse colitis model.
ALPN-101 and ALPN-202 Clinical Trials Ongoing. A phase 1b/2 trial of ALPN-101 in acute GVHD (BALANCE, NCT04227938) has been initiated. The NEON-1 trial of ALPN-202 (NCT04186637) is open for enrollment.
"The first quarter was a highly productive one, with now two open clinical studies for both our lead product candidates," said Mitchell H. Gold, M.D., Executive Chairman and Chief Executive Officer of Alpine. "We were gratified to receive orphan drug designations for ALPN-101 in acute GVHD, where current standard therapies remain inadequate to prevent or control the disease. We also reiterate our excitement over ALPN-202, which is now poised clinically to address a potential key mechanism accounting for checkpoint inhibitor resistance."

First Quarter 2020 Financial Results

As of March 31, 2020, Alpine had cash, cash equivalents, restricted cash, and short-term investments totaling $36.1 million. Net cash used in operating activities for the first quarter ended March 31, 2020 was $9.7 million compared to $11.2 million for the first quarter ended March 31, 2019. Alpine recorded a net loss of $5.5 million and $12.4 million for the first quarters ended March 31, 2020 and 2019, respectively.
Research and development expenses for the first quarter ended March 31, 2020 were $4.9 million compared to $10.4 million for the first quarter ended March 31, 2019.
General and administrative expenses for the first quarter ended March 31, 2020 were $1.8 million compared to $2.3 million for the first quarter ended March 31, 2019.
Cash Guidance

Alpine expects to have sufficient cash to fund its planned operations for at least the next 12 months, including the clinical advancement of Alpine’s lead autoimmune/inflammatory program, ALPN-101, and its lead oncology program, ALPN-202.

For additional information regarding Alpine’s planned operations, please refer to "Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operation – Liquidity and Capital Resources" in Alpine’s Quarterly Report on Form 10-Q for the three months ended March 31, 2020, which Alpine anticipates filing with the Securities and Exchange Commission on or about May 14, 2020.

About ALPN-101

ALPN-101 is a novel Fc fusion protein of a human inducible T cell costimulator ligand (ICOSL) variant immunoglobulin domain (vIgD), a first-in-class therapeutic designed to inhibit simultaneously the CD28 and ICOS inflammation pathways. CD28 and ICOS are closely related costimulatory molecules with partially overlapping roles in T cell activation likely playing a role in multiple autoimmune and inflammatory diseases. In preclinical models of graft versus host disease, inflammatory arthritis, connective tissue disease, and multiple sclerosis, ALPN-101 demonstrates efficacy superior to agents blocking the CD28 – CD80/86 and/or ICOS – ICOSL pathways alone. A phase 1b/2 trial of ALPN-101 in acute GVHD (BALANCE, NCT04227938) has been initiated.

About ALPN-202

ALPN-202 is a first-in-class, conditional CD28 costimulator and dual checkpoint inhibitor with the potential to improve upon the efficacy of combined checkpoint inhibition while limiting significant toxicities. Preclinical studies of ALPN-202 have successfully demonstrated superior efficacy in tumor models compared to checkpoint inhibition alone. A phase 1 trial of ALPN-202 in advanced malignancies (NEON-1, NCT04186637) is open for enrollment.

On May 14, 2020 Leap Therapeutics, Inc. (Nasdaq:LPTX), a biotechnology company focused on developing targeted and immuno-oncology therapeutics, reported financial results for the first quarter ended March 31, 2020 (Press release, Leap Therapeutics, MAY 14, 2020, View Source [SID1234558008]).

Leap hosted a conference call with Rebecca Arend, M.D., Assistant Professor and Associate Scientist, Gynecologic Oncology Clinic, The University of Alabama at Birmingham School of Medicine Comprehensive Cancer Center Experimental Therapeutics Program, on April 23, 2020, to discuss the data. Key findings from the P204 Study include the following:

DKN-01 Single Agent Activity

○Endometrial Cancer: Twenty-nine endometrial cancer patients were enrolled in the DKN-01 monotherapy arm, over 75% of whom had experienced three or more prior lines of therapy. Of those patients, 26 were evaluable for response. In the 20 patients with a Wnt signaling alteration, one patient (5%) has an ongoing complete response, one patient (5%) had a partial response, eight patients (40%) had a best response of stable disease, and 10 patients (50%) had progressive disease, representing an overall response rate (ORR) of 10% and a disease control rate (DCR) of 50%. In the group of six patients without any Wnt signaling alterations, one patient (16.6%) had a best response of stable disease and five patients (83.3%) had progressive disease.

○Carcinosarcoma: Ten patients with carcinosarcoma have been enrolled in the DKN-01 monotherapy arm, five of whom were evaluable for response as of the data-cut off date. Two patients (40%) had a best response of stable disease, one of whom has continued on monotherapy for nearly two years, and three patients (60%) had progressive disease. Five patients had not reached their first tumor assessment.

DKN-01 plus Paclitaxel Combination Activity

○Carcinosarcoma: Fifteen patients with carcinosarcoma were enrolled in the DKN-01 plus paclitaxel arm, six of whom were evaluable for response as of the data-cut off date. Two patients (33%) have had a partial response, one patient (17%) has had a best response of stable disease, and three patients (50%) had progressive disease, representing an ORR of 33% and a DCR of 50%. Nine patients had not reached their first tumor assessment.

○Endometrial Cancer: Twenty-five patients with heavily pretreated endometrial cancer were enrolled in the DKN-01 plus paclitaxel arm. All of these patients had previously received paclitaxel, 44% had received hormonal therapies, 32% had received bevacizumab, 20% had received immunotherapy, and 12% had received a PARP inhibitor. Of those patients, 22 were evaluable for response. A total of 12 patients (55%) have had a best response of stable disease, and ten patients (45%) had progressive disease.

○Monotherapy Patients with Wnt activating mutations have longer Progression-Free Survival (PFS) and Overall Survival (OS): In a pooled analysis of all DKN-01 monotherapy patients, patients with Wnt activating mutations have demonstrated a longer median PFS of 168 days as compared to patients without Wnt activating mutations with median PFS of 56 days. Median OS has not been reached in the Wnt activating mutation group in the pooled analysis as compared to median OS of 328 days in the non-Wnt activating mutation group.

○Monotherapy Patients with DKK1-high tumors have longer PFS and OS: DKK1 expression as measured by in situ hybridization RNAscope assay is currently available for 68 of the patients on the study, 32 of whom were treated with DKN-01 monotherapy. Seven patients (22%) were identified as having DKK1-high tumoral expression (DKK1-high). Consistent with the results from Leap’s study in patients with esophagogastric cancer, patients whose tumors are DKK1-high have prolonged median PFS of 168 days as compared to patients with tumors that are DKK1-low with median PFS of 56 days. Median OS was 450 days in the DKK1-high group in the pooled analysis as compared to 276 days in the DKK1-low group.

·Leap Presented Final Data for DKN-01 plus KEYTRUDA (pembrolizumab) in Esophagogastric Cancer: Leap completed its multi-part Phase 1/2 clinical study of DKN-01, as a monotherapy and in combination with paclitaxel or KEYTRUDA (pembrolizumab), in patients with advanced esophagogastric cancer. At the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2020 Gastrointestinal Cancers Symposium, Leap presented final data for the combination of DKN-01 plus pembrolizumab. The combination of DKN-01 and pembrolizumab in gastroesophageal junction cancer (GEJ) and gastric cancer (GC) patients demonstrated improved outcomes in DKK1-high patients who had not previously been treated with PD-1/PD-L1 therapy. DKK1-high patients experienced over 22 weeks median PFS and nearly 32 weeks median OS, with a 50% ORR and 80% DCR in ten evaluable patients. DKK1-low patients experienced nearly 6 weeks median PFS and over 17 weeks OS, with a 20% DCR in 15 evaluable patients.

·Site Initiation Activities Underway for DKN-01 plus Tislelizumab Combination Study: As part of the collaboration with BeiGene, Leap intends to study the combination of DKN-01 and BeiGene’s anti-PD-1 antibody, tislelizumab. The Company plans to evaluate approximately 40 patients with second-line GC or GEJ whose tumors are DKK1-high. In addition, Leap will evaluate the combination of DKN-01 with tislelizumab and chemotherapy in approximately 20 patients with first-line GC or GEJ. Site initiation activities for this clinical trial are underway, and the Company expects to dose the first patients in the second half of 2020.

Selected First Quarter 2020 Financial Results

Net loss was $7.2 million for the first quarter 2020, compared to $8.6 million for the same period in 2019. This decrease was primarily due to revenue recognized from the BeiGene agreement and a decrease in clinical development expenses, offset by a non-cash charge for foreign currency losses associated with changes in the Australian dollar exchange rate related to activities of Leap’s Australian subsidiary.

Research and development expenses was $4.6 million for the first quarter 2020, compared to $6.8 million for the same period in 2019. The decrease was primarily due to decreases in clinical trial costs due to timing of patient enrollment and decreases in consulting fees associated with research and development activities.

General and administrative expenses was $2.2 million for the first quarter 2020, compared to $2.0 million for the same period in 2019. The increase was primarily due to increases in legal, audit and consulting fees associated with corporate and business development activities.

Cash, cash equivalents and marketable securities totaled $25.5 million at March 31, 2020. Research and development incentive receivables, current and long term, totaled approximately $0.2 million at March 31, 2020.
