"We are in the process of requesting a pre-NDA meeting with the FDA and look forward to reviewing this data with the agency. In addition, the BLA for ROLONTIS is under active FDA review with a PDUFA date of October 24, 2020. We are in a strong capital position to fund our ongoing development and commercialization of our late stage assets."

Pipeline Updates

Poziotinib, an irreversible tyrosine kinase inhibitor targeting EGFR and HER2 mutations

Poziotinib met the pre-specified primary endpoint for Cohort 2 in the ZENITH20 Phase 2 clinical trial evaluating previously treated non-small cell lung cancer (NSCLC) patients with HER2 exon 20 insertion mutations. Cohort 2 of the ZENITH20 clinical trial enrolled a total of 90 patients who received an oral, once daily dose of 16 mg/day of poziotinib. All responses were read independently and confirmed by a central imaging laboratory using RECIST criteria. The intent-to-treat analysis demonstrated a confirmed objective response rate (ORR) of 27.8% (95% Confidence Interval (CI) 18.9%-38.2%). Based on the pre-specified statistical hypothesis for the primary endpoint, the observed lower bound of 18.9% exceeded the pre-specified lower bound of 17% in this heavily pre-treated population.
The median duration of response was 5.1 (range 1 to >12.3) months, with a median follow up of 8.3 months. The disease control rate (DCR) was 70% and the median progression free survival was 5.5 months.
Spectrum plans to present additional results from Cohort 2 at a medical meeting later in the year.
The company is in the process of requesting a pre-NDA meeting with the FDA based on the positive results from Cohort 2 to seek an indication for the treatment of patients with previously treated locally advanced or metastatic NSCLC with HER2 exon 20 insertion mutations.
Cohort 3 of the ZENITH20 trial in first-line EGFR NSCLC patients is fully enrolled and topline results are expected by year-end 2020.
ROLONTIS (eflapegrastim), a novel long-acting G-CSF

FDA is actively reviewing the BLA for ROLONTIS for the treatment of chemotherapy-induced neutropenia. The PDUFA target action date for the ROLONTIS BLA is October 24, 2020.

Verastem’s sale of COPIKTRA follows the Company’s previously announced strategic direction to focus on maximizing the broad potential of its RAF/MEK inhibitor (VS-6766) and FAK inhibitor (defactinib) program in KRAS mutant (KRASmt) solid tumors. Upon closing of the transaction with Secura Bio, Verastem will be dedicated to the development of this program and to deliver on clinical and regulatory milestones for the first potential indications in low-grade serous ovarian cancer (LGSOC) and KRASmt non-small cell lung cancer (NSCLC). Both LGSOC and KRASmt NSCLC are areas of high unmet patient need as there are no approved treatments and existing therapies have low response rates.

"By focusing our expertise and efforts on rapidly advancing the RAF/MEK/FAK development program, we believe we will be providing the best path forward for patients, customers, our shareholders and our company. These strategic decisions will enable us to best deliver on our mission to advance new medicines on behalf of cancer patients," said Brian Stuglik, Chief Executive Officer of Verastem Oncology. "The agreement with Secura Bio will ensure COPIKTRA continues to help more patients, leveraging the established commercial structure, support of ongoing clinical study and potential expansion into new indications."

Terms of the Definitive Sale Agreement

Verastem will receive an up-front payment of $70 million upon the closing of the transaction and is eligible to receive up to a total deal value of $311 million if certain regulatory and sales-based milestones are successfully met by Secura Bio and COPIKTRA’s other rest-of-world partners, including:

· A total of $45 million from two separate milestone payments for U.S. Food and Drug Administration (FDA) and European Medicines Agency approvals of COPIKTRA with label indicated for peripheral T-cell lymphoma
· A total of $50 million for cumulative worldwide net sales of COPIKTRA beginning at $100 million of cumulative net sales
· Verastem will receive low double-digit royalties on net sales over $100 million in U.S., Europe and the United Kingdom
· Verastem will also receive 50% of licensing milestones (up to $146 million) and royalties outside of U.S., Europe and the United Kingdom

In exchange, Secura Bio will receive an exclusive worldwide license for the research, development, commercialization and manufacture of COPIKTRA in all oncology indications. Secura Bio will assume all operational and financial responsibility for activities that were previously part of Verastem’s duvelisib program, including commercialization efforts in the United States and Europe, ongoing clinical trials, Verastem’s partnerships with Yakult, CSPC and Sanofi and existing royalty obligations. Secura Bio and Verastem are also in discussions related to the transfer of Verastem’s field sales and medical professionals.

The transaction with Secura Bio is subject to customary closing conditions and is expected to close in the third quarter of 2020.*

VS-6766 and Defactinib Program Progress and Registration-Directed Trials

Verastem announced today that the company met with the FDA in July 2020 to discuss the registration-directed study design for the VS-6766/defactinib combination in patients with LGSOC. The FDA was supportive of the Company’s development strategy and adaptive design for LGSOC.

Verastem’s NSCLC study will also be an adaptive design with a focus on patients with KRAS-G12V mutant tumors. Verastem intends to seek input from the FDA after completing the initial cohort of the lung cancer study. Verastem expects to commence registration-directed clinical trials for potential accelerated approval in LGSOC and KRASmt NSCLC by the end of 2020.

Verastem is continuing its clinical collaboration with the Drug Development Unit at ICR/Royal Marsden Hospital. The ongoing investigator-initiated Phase 1/2 FRAME study evaluating the combination of VS-6766 with defactinib in LGSOC, KRASmt NSCLC and colorectal cancer (CRC) has resumed normal accrual and reporting rates following the global lockdown resulting from the COVID-19 pandemic. The FRAME study is now expanding to include new cohorts in pancreatic cancer, KRASmt endometrial cancer and KRAS-G12V NSCLC. Verastem expects that additional data from the LGSOC cohort of the FRAME study will be made available in September, including presentation at the 2nd Annual RAS-Targeted Drug Development Conference. The Company also expects that additional data from the NSCLC cohort of the FRAME study will be submitted to the International Association for the Study of Lung Cancer (IASLC) World Lung Cancer Conference, taking place in January 2021.

The Company has also begun preclinical combination studies investigating VS-6766 and defactinib in combination with KRAS-G12C inhibitors and initial data will be presented at the 2nd Annual RAS-Targeted Drug Development Conference. Based on the positive preclinical data presented at the AACR (Free AACR Whitepaper) 2020 Virtual Annual Meeting II, Verastem plans to support a Phase 2 investigator-initiated study evaluating the combination of VS-6766 and defactinib in uveal melanoma, which is expected to begin in late 2020.

Corporate and Financial Overview

With the sale of COPIKTRA, Verastem will become a focused development company with reduced annual expenses of approximately $50 million. The company is in a position of financial strength with a cash runway expected to fund the clinical and regulatory milestones and development of VS-6766 and defactinib in LGSOC and KRASmt NSCLC until at least 2024.

About VS-6766
VS-6766 (formerly known as CH5126766, CKI27 and RO5126766) is a unique inhibitor of the RAF/MEK signaling pathway. In contrast to other MEK inhibitors in development, VS-6766 blocks both MEK kinase activity and the ability of RAF to phosphorylate MEK. This unique mechanism allows VS-6766 to block MEK signaling without the compensatory activation of MEK that appears to limit the efficacy of other inhibitors.

About Defactinib

Defactinib (VS-6063) is an oral small molecule inhibitor of FAK and PYK2 that is currently being evaluated as a potential combination therapy for various solid tumors. The Company has received Orphan Drug designation for defactinib in ovarian cancer and mesothelioma in the US, EU and Australia. Preclinical research by Verastem Oncology scientists and collaborators at world-renowned research institutions has described the effect of FAK inhibition to enhance immune response by decreasing immuno-suppressive cells, increasing cytotoxic T cells, and reducing stromal density, which allows tumor-killing immune cells to enter the tumor.1,2

About the VS-6766/Defactinib Combination

RAS mutant tumors are present in 30% of all human cancers and have historically presented a difficult treatment challenge and are often associated with significantly worse prognosis. Challenges associated with identifying new treatment options for these types of cancers include resistance to single agents, identifying tolerable combination regimens with MEK inhibitors and new RAS inhibitors in development addressing only a minority of all RAS mutated cancers.

The combination of VS-6766 and defactinib has been found to be clinically active in KRASmt. In an ongoing investigator-initiated Phase I/2 FRAME study, the combination of VS-6766 and defactinib is being evaluated in patients with LGSOC, KRASmt NSCLC and colorectal cancer (CRC). Preliminary data from this study presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) 2020 Virtual Annual Meeting I demonstrated a 67% overall response rate and long duration of therapy among patients with KRASmt LGSOC. Based on an observation of higher response rates seen in patients with KRAS-G12V mutations in the study, Verastem will also be further exploring the role of VS-6766 and defactinib in KRAS-G12V NSCLC. The FRAME study is expanding in August 2020 to include new cohorts in pancreatic, KRASmt endometrial and KRAS-G12V NSCLC.

About COPIKTRA (duvelisib)

COPIKTRA is an oral inhibitor of phosphoinositide 3-kinase (PI3K), and the first approved dual inhibitor of PI3K-delta and PI3K-gamma, two enzymes known to help support the growth and survival of malignant B-cells. PI3K signaling may lead to the proliferation of malignant B-cells and is thought to play a role in the formation and maintenance of the supportive tumor microenvironment.3,4,5 COPIKTRA is indicated for the treatment of adult patients with relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) after at least two prior therapies and relapsed or refractory follicular lymphoma (FL) after at least two prior systemic therapies. COPIKTRA is also being developed by Verastem Oncology for the treatment of peripheral T-cell lymphoma (PTCL), for which it has received Fast Track status and Orphan Drug Designation, and is being investigated in combination with other agents through investigator-sponsored studies.6 For more information on COPIKTRA, please visit www.COPIKTRA.com.

"Despite the operating challenges posed by the global pandemic, we continued to advance our pegzilarginase program in the first half of the year. The presentation of long-term data showing sustained lowering of arginine levels and durable clinical response with pegzilarginase treatment, as well as progress in our patient identification efforts, reinforce our belief in its potential as a life-changing therapy for those with Arginase 1 Deficiency and lay a strong foundation for the commercial launch of pegzilarginase," said Anthony Quinn, M.B Ch.B, Ph.D., president and chief executive officer of Aeglea. "Additionally, we initiated our Phase 1/2 clinical trial of ACN00177 for Homocystinuria in the second quarter. We are continuing our patient identification activities and look forward to dosing the first patient once the clinical sites are able to begin screening patients."

Recent Highlights and Updates

Pegzilarginase in Arginase 1 Deficiency

In May, Aeglea presented results from its 56 week analysis from the Company’s completed Phase 1/2 clinical trial and ongoing open-label extension study during a late-breaking oral presentation at the 6th Congress of the European Academy of Neurology. Key results include:

Treatment with pegzilarginase resulted in a significant reduction in plasma arginine from baseline with all 13 patients achieving plasma arginine levels within the target range (<200 µM).

85% (11 of 13) of patients were clinical responders based on mobility improvements evaluated using three assessments: 6MWT (6 Minute Walk Test), GMFM (Gross Motor Function) Part D (standing) and Part E (walking, running, and jumping).

Pegzilarginase was shown to have a favorable safety profile with more than 750 doses administered.

To date, Aeglea has identified more than 240 Arginase 1 Deficiency patients. The number of identified patients represents more than 50% and 30% of the estimated genetic prevalence patient population in the U.S. and key European markets (France, Germany, Spain, Italy and the United Kingdom), respectively.

ACN00177 in Homocystinuria

Aeglea initiated its Phase 1/2 clinical trial for ACN00177, a novel engineered human enzyme therapy designed to treat Homocystinuria, a serious metabolic disorder characterized by elevated plasma homocysteine which leads to a wide range of life-altering complications and reduced life expectancy.

Corporate

Eric Bradford, M.D., M.Sc., M.B.A. has been promoted to Chief Development Officer. Dr. Bradford will oversee the clinical programs for pegzilarginase and ACN00177 as well as shape the clinical development strategy for future programs from the Company’s platform of novel human enzymes.

Chief Medical Officer Ravi M. Rao, M.B BChir, Ph.D., will depart the company to pursue other opportunities. Dr. Rao will continue to support Aeglea in a medical advisor role through a transitional period.

"Ravi has been a valued and impactful member of the Aeglea team. While we are disappointed by his planned departure, we wish him the best as he returns to his roots in immunology research and development," said Dr. Quinn. "I look forward to working more closely with Eric as we continue to strengthen our capabilities and advance pegzilarginase towards potential approval and launch."

Upcoming Events

Aeglea will be attending the following virtual investor conferences in the coming quarter.

Wells Fargo Securities Healthcare Conference, September 9-10

H.C. Wainwright Healthcare Conference, September 13-15

Cantor Fitzgerald Global Healthcare Conference, September 15-17

Further, Aeglea’s leadership looks forward to participating in dialogue about the Company’s enzyme therapeutics platform during the following industry events, with additional details to be announced.

World Orphan Drug Congress USA 2020, August 24-26

Child Neurology Society Annual Meeting-International Child Neurology Congress 2020, October 19-23

Second Quarter 2020 Financial Results

As of June 30, 2020, Aeglea had available cash, cash equivalents, marketable securities and restricted cash of $159.2 million. Based on Aeglea’s current operating plans, management believes it has sufficient capital resources to fund anticipated operations through 2022.

Research and development expenses totaled $16.9 million for the second quarter of 2020 and $14.8 million for the second quarter of 2019. The increase was primarily associated with investing in manufacturing and pre-commercial activities for Aeglea’s lead product candidate, pegzilarginase; ramp-up in manufacturing activities for ACN00177 in Homocystinuria; and personnel-related expenses offset by decreasing clinical development expenses as a result of completing a Phase 1/2 clinical trial in patients with Arginase 1 Deficiency and closing out cancer trials.

General and administrative expenses totaled $4.7 million for the second quarter of 2020 and $3.8 million for the second quarter of 2019. This increase was primarily due to additional employee headcount, ramping up commercial capabilities, and additional facilities to support company growth.

Net loss totaled $21.4 million and $18.0 million for the second quarter of 2020 and 2019, respectively, with non-cash stock compensation expense of $1.6 million and $1.2 million for the second quarter of 2020 and 2019, respectively.

About Pegzilarginase in Arginase 1 Deficiency

Pegzilarginase is an enhanced human arginase that enzymatically lowers levels of the amino acid arginine. Aeglea is developing pegzilarginase for the treatment of patients with Arginase 1 Deficiency (ARG1-D), a rare debilitating, progressive disease presenting in childhood with persistent hyperargininemia, spasticity, developmental delay, intellectual disability, seizures and early mortality. Pegzilarginase is intended for use as an enzyme therapy to reduce elevated blood arginine levels in patients with ARG1-D. Aeglea’s Phase 1/2 and Phase 2 open-label extension data for pegzilarginase in patients with ARG1-D demonstrated clinical improvements and sustained lowering of plasma arginine. The Company’s single, global pivotal Phase 3 PEACE trial is designed to assess the effects of treatment with pegzilarginase versus placebo over 24 weeks with a primary endpoint of plasma arginine reduction.

About ACN00177 in Homocystinuria

Aeglea is developing ACN00177 for the treatment of patients with cystathionine beta synthase (CBS) deficiency, also known as Classical Homocystinuria. Homocysteine accumulation plays a key role in multiple progressive and serious disease-related complications, including thromboembolic vascular events, skeletal abnormalities including severe osteoporosis, developmental delay, intellectual disability, lens dislocation and severe near-sightedness. ACN00177 has been designed as a novel recombinant human enzyme, which degrades the amino acid homocysteine and its related homocystine dimer. With this mechanism, ACN00177 is intended to lower the abnormally high blood levels of homocysteine in patients with Homocystinuria. Preclinical data demonstrated that ACN00177 improved important disease-related abnormalities and survival in a mouse model of Homocystinuria. The Company initiated a Phase 1/2 trial in the second quarter of 2020 and continues patient identification and administrative activities. The timing of first patient dosing in this Phase 1/2 trial will depend on determinations by individual sites as they adjust to impacts from COVID-19.

Cellectar Reports Second Quarter 2020 Financial Results and Provides a Corporate Update

"We continue to enroll relapsed/refractory multiple myeloma and LPL/WM patients in the Phase 2b portion of our ongoing CLOVER-1 study and prepare for the initiation of our pivotal study expected in Q4 of 2020 while advancing our Phase 1 pediatric study " said James Caruso, president and CEO of Cellectar. "We also successfully executed on other key fronts. The FDA granted CLR 131 Fast Track Designation in LPL/WM; we expanded our IP portfolio with two new European patents and significantly strengthened our balance sheet with the recent financing."

Second Quarter 2020 Financial Highlights

·Cash and Cash Equivalents: As of June 30, 2020, the company had cash and cash equivalents of $22.5 million compared to $10.6 million at December 31, 2019. Cash used in operating activities was approximately $6.6 million during the six months ended June 30, 2020 as compared to $5.5 million during the six months ended June 30, 2019.

·Research and Development Expense: R&D expense for the three months ended June 30, 2020 was $2.5 million, compared to $1.8 million for the three months ended June 30, 2019. The cumulative R&D spending for the first six months of 2020 was $5.1 million as compared to $4.1 million for the first six months of 2019. The increase in R&D expense year-to-date in 2020 was primarily a result of general R&D cost from personnel related expenses and clinical project costs. Manufacturing and related costs decreased and the costs of preclinical studies were relatively consistent.

·General and Administrative Expense: G&A expense for the three months ended June 30, 2020 was $1.2 million compared to $1.4 million for the three months ended June 30, 2019. The cumulative G&A spending for the first six months of 2020 were of $2.5 million as compared to $2.7 million for the first six months of 2019. The decrease in G&A expense year-to-date in 2020 was primarily a result of lower stock-based compensation expense.

Net Loss: The net loss attributable to common stockholders for the three months ended June 30, 2020 was ($3.6) million, or ($0.26) per share, compared to ($3.2) million, or ($0.46) per share, in 2019. Net loss attributable to common stockholders for the six months ended June 30, 2020 was ($7.6) million, or ($0.65) per share, compared to ($6.8) million, or ($1.15) per share, in 2019.

"While we are disappointed with the recent interim analysis results from our ongoing ECLIPSE trial, we look forward to additional Phase 2 clinical trial readouts anticipated over the upcoming quarters," said Hamza Suria, president and chief executive officer of AnaptysBio. "We remain focused on the continued discovery and development of novel antibodies using our capital-efficient business model which has already advanced 7 internally-generated antibodies to the clinic to date. We also anticipate significant milestone and royalty revenues from the FDA approval of dostarlimab under our GSK partnership."

Etokimab (ANB020 Anti-IL-33) Program
•In an interim analysis at week 8 of the ongoing ECLIPSE Phase 2 trial of etokimab in chronic rhinosinusitis with nasal polyps, patients dosed with etokimab every four (q4w) or eight weeks (q8w) failed to achieve statistically significant improvement in their bilateral nasal polyps score (NPS), an endoscopic measure of nasal occlusion, and their sino-nasal outcome test (SNOT-22), a patient reported quality-of-life assessment, versus placebo at the week 8 timepoint. Both endpoints demonstrated statistically significant improvement over baseline levels of NPS and SNOT-22. Blood eosinophil levels, which are a biomarker of etokimab’s mechanism, demonstrated statistically significant reduction relative to baseline in both etokimab treatment arms. The Company intends to decide on a path forward for the etokimab program after reviewing week 16 primary endpoint data by year-end 2020.

Imsidolimab (Anti-IL-36 Receptor) Program
•In July we announced that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation for imsidolimab, the company’s proprietary anti-interleukin-36 receptor (IL-36R) antibody, for the treatment of patients with GPP. Treatment of GPP by imsidolimab is being evaluated in the GALLOP Phase 2 trial, where additional clinical data and a regulatory update is anticipated in the fourth quarter of 2020.
•The Company is also conducting a randomized, placebo-controlled, multi-dose Phase 2 trial in 50 patients with palmoplantar pustulosis, or PPP, also known as the POPLAR trial, with topline data anticipated in the first quarter of 2021, following COVID-19-related site closures that impacted enrollment in POPLAR during the second quarter.
•We anticipate expanding the imsidolimab program in two new indications based upon human translational data that suggests each of these conditions are mediated by dysregulated signaling through the IL-36 pathway:
◦Treatment of solid tumors with inhibitors of epidermal growth factor (EGFRi) and MAPK/ERK kinase (MEKi) is frequently limited by the occurrence of skin toxicities. These toxicities, which can lead to dose reduction and discontinuation of treatment, have been reported to occur as a result of excess IL-36 signaling, leading to IL-8-mediated cutaneous neutrophilia and acneiform rash. Based on existing claims data, approximately 60,000 patients are prescribed EGFRi and/or MEKi treatments annually, and the vast majority of these patients experience dermatological toxicity. Current standard-of-care treatments are generally ineffective in patients with the most severe grades of EGFRi and/or MEKi mediated acneiform rash. During the fourth quarter of 2020, we anticipate initiating a Phase 2 trial of imsidolimab, in combination with EGFRi/MEKi inhibitors, to assess its efficacy in the treatment of this indication.
◦Ichthyosis is a family of rare, inherited, dermatological disorders characterized by dry, scaling and thickened skin. Approximately 6,000 patients in the United States are affected with moderate-to-severe levels of ichthyosis and no approved therapies are available for this disease. Recent translational data supports the role of IL-36 signaling in ichthyosis, and we anticipate initiating a Phase 2 trial of imsidolimab in this indication during the fourth quarter of 2020.

ANB030 (Anti-PD-1 Agonist) Program
•ANB030 is a wholly-owned antibody that binds PD-1 in an agonistic manner, leading to reduced T cell activity and anti-inflammatory effects in vivo. Genetic mutations in the PD-1 pathway are associated with increased susceptibility to various inflammatory conditions and we believe ANB030 has the potential to suppress inflammatory diseases by restoring insufficient PD-1-mediated negative signaling on activated T cells. The Company plans to focus future clinical development of ANB030 on certain autoimmune diseases where PD-1 checkpoint receptor function may be under-represented. Preclinical translational data using ANB030 was presented in March 2020 at the Festival of Biologics Meeting. We initiated a Phase 1 healthy volunteer clinical trial, designed to assess the safety, pharmacokinetics and pharmacodynamics of ANB030 in single and multiple ascending dose cohorts, during the first half of 2020, and top-line data from this trial is anticipated in mid-2021.

ANB032 (Anti-BTLA Modulator) Program
•Our fourth wholly-owned program is an anti-BTLA modulator antibody, known as ANB032, which is broadly applicable to human inflammatory diseases associated with lymphoid and myeloid immune cell dysregulation. Mutations in the BTLA signaling pathway are associated

with human inflammatory disease, and we believe ANB032 silences pro-inflammatory signaling by modulating BTLA binding to HVEM. We anticipate filing an IND for ANB032 in the fourth quarter of 2020.
Dostarlimab (Anti-PD-1 Antagonist) Program Partnered with GSK
•In the first quarter of 2020, the FDA accepted the first Biologics License Application (BLA) filing for dostarlimab, an AnaptysBio-generated PD-1 antagonist antibody under partnership with GSK, for the treatment of advanced or recurrent deficient mismatch repair (dMMR) endometrial cancer. AnaptysBio received a $10.0 million cash milestone payment upon this acceptance, and anticipates an additional $20.0 million cash milestone payment upon first FDA approval of dostarlimab during the second half of 2020. Also in the first quarter of 2020, the EMA accepted GSK’s Marketing Authorization Application (MAA) for approval of dostarlimab in the EU for endometrial cancer, for which AnaptysBio has received a $5.0 million milestone payment and anticipates an additional $10.0 million cash milestone payment upon EMA approval.
•AnaptysBio also expects to receive milestone payments from GSK during 2021 for acceptance and approval by the FDA of dostarlimab in dMMR pan-tumor cancer. All milestone payment amounts for this second indication for dostarlimab will be the same as the corresponding milestone payment amounts for the first indication.
•Including additional cash milestones due upon future development and commercialization of dostarlimab, GSK4069889A, an AnaptysBio-generated TIM-3 antibody, and GSK4074386, an AnaptysBio-generated LAG-3 antibody, AnaptysBio can potentially receive a total of $1.1 billion in aggregate milestone payments under this GSK partnership. In addition, AnaptysBio is due a 4% to 8% royalty from GSK, tiered upon global sales, for each of the aforementioned programs.
Second Quarter Financial Results
•Cash, cash equivalents and investments totaled $392.2 million as of June 30, 2020 compared to $428.5 million as of December 31, 2019, for a decrease of $36.3 million. The decrease relates primarily to cash used for operating activities.
•Collaboration revenue was zero and $15.0 million for the three and six months ended June,30 2020, which related to milestone payments for successful BLA and MAA filings for dostarlimab by GSK, compared to $5 million for both the three and six months ended June 30, 2019.
•Research and development expenses were $17.9 million and $38.9 million for the three and six months ended June 30, 2020, compared to $27.4 million and $48.0 million for the three and six months ended June 30, 2019. The decrease was due primarily to reduced outside services for manufacturing expenses based on the timing of projects.
•General and administrative expenses were $4.7 million and $9.0 million for the three and six months ended June 30, 2020, compared to $4.3 million and $8.4 million for the three and six months ended June 30, 2019. The increase was due primarily to increased legal and insurance expenses.
•Net loss was $21.5 million and $29.8 million for the three and six months ended June 30, 2020, or a net loss per share of $0.79 and $1.09, compared to a net loss of $24.0 million and $46.0 million for the three and six months ended June 30, 2019, or a net loss per share of $0.89 and $1.70.
Financial Guidance
AnaptysBio expects its net cash burn in 2020 will be approximately $60.0 million, and that its cash, cash equivalents and investments will fund its current operating plan at least into 2023.
