"It is of great interest to see the Drug Response Predictor work for 2X-121, and the clear separation between responders and non-responders. This bodes well for the future role of 2X-121 in the treatment of cancer," stated Dr. Mansoor R. Mirza, chief oncologist, Department of Oncology, Copenhagen University Hospital-Rigshospitalet.

"In this DRP validation study, the diagnostic identified responders irrespective of BRCA mutation status, indicating that our compound may have broader application including tumors resistant to other PARP inhibitors," said George O. Elston, CEO of 2X Oncology.

2X-121 is a small molecule targeted inhibitor of Poly ADP ribose polymerase (PARP), a key enzyme involved in DNA damage repair in cancer cells. The drug candidate has a novel dual-inhibitory action against both PARP 1/2 and Tankyrase 1/2. The molecule is also active in P-glycoprotein expressing cells, suggesting it may overcome PARP inhibitor resistance.

"PARP inhibitors are the most exciting new class of agent for the treatment of many gynecologic cancers," said Ursula Matulonis, M.D., Director, Gynecologic Oncology at the Dana-Farber Cancer Institute and Professor of Medicine, Harvard Medical School. "Therapeutics such as 2X-121 that can overcome PARP inhibitor resistance, an important clinical problem today, will be a significant and welcome addition to the oncologists’ toolkit."

The drug candidate demonstrated clinical activity in a Phase 1 study in a number of cancers, including ovarian and breast. 2X-121 also has potential to treat brain metastases and primary brain tumors based on its ability to pass through the blood-brain barrier.

Separate, targeted Phase 2 studies of 2X-121 are planned using the validated DRP biomarker in metastatic breast cancer and recurrent ovarian cancer to identify patients likely to respond to and benefit from treatment with the drug.

"We look forward to the initiation of the Phase 2 clinical trials for 2X-121, leveraging the initial Phase 1 responder data and the validated DRP, later this year," Elston added.

Positive data from these studies will position the program for a pivotal Phase 2 study initiation as early as 2018.

In a blinded study of 13 patients, five of seven patients in the DRP-predicted responder group survived (Overall Survival-OS) at 400 days from commencement of treatment, compared with only one out of six patients surviving at 400 days for those predicted by the DRP score to be non-responders. This equates to a four-fold difference in overall survival between the patients predicted to respond and those not predicted to respond to treatment.

The DRP correctly predicted response to treatment and overall survival with a p-value of 0.07 and a hazard ratio on overall survival of 0.26 in this study.

About the Drug Response Predictor (DRP) Companion Diagnostic

Developed by and in-licensed from Medical Prognosis Institute A/S (MPI.ST), the DRP screening platform utilizes messenger RNA (mRNA) gene expression signatures from patient biopsies to identify patients with a high likelihood of responding to specific cancer-fighting therapies. This DRP method builds on the comparison of sensitive vs. resistant human cancer cell lines, including genomic information from cell lines, combined with clinical tumor biology and clinical correlates in a systems biology network. Specific DRPs are developed for each pipeline product, which will enable 2X Oncology to identify and predict which patients are most likely to respond and thereby benefit from a given pipeline product. This would enable likely responders to receive appropriate treatment while expediting the decision path for predicted non-responders, saving them critical time and money in their cancer fight.

Unless otherwise stated, all comparisons are for the second quarter and six months ended June 30, 2017, compared to the second quarter and six months ended June 30, 2016.

Based on accounting principles generally accepted in the United States (GAAP), Puma reported a net loss applicable to common stock of $77.8 million, or $2.10 per share, for the second quarter of 2017, compared to a net loss applicable to common stock of $66.6 million, or $2.05 per share, for the second quarter of 2016. Net loss applicable to common stock for the first six months of 2017 was $150.7 million, or $4.08 per share, compared to $137.6 million, or $4.23 per share, for the first six months of 2016.

Non-GAAP adjusted net loss was $50.9 million, or $1.38 per share, for the second quarter of 2017, compared to non-GAAP adjusted net loss of $37.9 million, or $1.17 per share, for the second quarter of 2016. Non-GAAP adjusted net loss for the first six months of 2017 was $94.0 million, or $2.54 per share, compared to non-GAAP adjusted net loss of $79.3 million, or $2.44 per share, for the first six months of 2016. Non-GAAP adjusted net loss excludes stock-based compensation expense, which represents a significant portion of overall expense and has no impact on the cash position of the Company. For a reconciliation of GAAP net loss to non-GAAP adjusted net loss and GAAP net loss per share to non-GAAP adjusted net loss per share, please see the financial tables at the end of this news release.

Net cash used in operating activities for the second quarter of 2017 was $45.9 million. Net cash used in operating activities for the first six months of 2017 was $82.0 million. At June 30, 2017, Puma had cash and cash equivalents of $80.8 million and marketable securities of $70.8 million, compared to cash and cash equivalents of $194.5 million and marketable securities of $35.0 million at December 31, 2016.

"During the second quarter of 2017, we achieved a significant milestone for Puma with the U.S. Food and Drug Administration’s (FDA) Oncologic Drugs Advisory Committee meeting, which led to last month’s FDA approval of NERLYNX (neratinib) for the extended adjuvant treatment of HER2-positive early stage breast cancer. This marked a major milestone for breast cancer patients and for Puma," said Alan H. Auerbach, Chairman, Chief Executive Officer and President of Puma. "Despite advances in early stage HER2-positive breast cancer treatment, there continues to be a need to reduce the risk of disease recurrence. NERLYNX has been demonstrated to significantly reduce that risk and offers physicians and their patients another treatment option. NERLYNX is now commercially available by prescription in the United States. We are also working with the European Medicines Agency (EMA) on their review of our marketing authorization application (MAA) for this indication and we expect the Committee for Medicinal Products for Human Use (CHMP), the scientific committee of the EMA, to issue an opinion regarding the MAA for neratinib in the first quarter of 2018."

Mr. Auerbach added, "Also, during the second quarter, we presented data at the 2017 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting from a Phase II trial of neratinib, which highlighted positive results from the TBCRC 022 trial in patients with HER2-positive metastatic breast cancer with brain metastases. In addition, during the quarter, we also achieved the targeted patient enrollment in our Phase III NALA trial of neratinib in patients with HER2-positive metastatic breast cancer who have failed two or more prior lines of HER2-directed treatments (third-line disease) in the setting of metastatic disease. We anticipate that primary analysis of data related to the NALA trial will be available during the first half of 2018.

"In the second half of this year, we anticipate the following clinical milestones: (i) presentation of the 5-year disease free survival (DFS) data from the ExteNET Phase III trial of NERLYNX as an extended adjuvant treatment in HER2-positive early stage breast cancer in the third quarter of 2017 and (ii) reporting additional data in the fourth quarter of 2017 from the Phase II trial of neratinib as an extended adjuvant treatment in HER2-positive early stage breast cancer using loperamide, budesonide and colestipol antidiarrheal prophylaxis."

Operating Expenses

Operating expenses were $78.2 million for the second quarter of 2017, compared to $66.5 million for the second quarter of 2016. Operating expenses for the first six months of 2017 were $151.4 million, compared to $137.7 million for the first six months of 2016.

Selling, General and Administrative Expenses:

Selling, general and administrative (SG&A) expenses were $24.9 million for the second quarter of 2017, compared to $12.3 million for the second quarter of 2016. SG&A expenses for the first six months of 2017 were $43.3 million, compared to $23.3 million for the first six months of 2016. The approximately $20.0 million increase during the first six months of 2017 compared to the first six months of 2016 resulted primarily from increases of approximately $2.6 million for stock-based compensation, $13.7 million for professional fees and expenses, and $2.1 million for payroll and related costs. These increases reflect overall corporate growth.

Research and Development Expenses:

Research and development (R&D) expenses were $53.3 million for the second quarter of 2017, compared to $54.2 million for the second quarter of 2016. R&D expenses for the first six months of 2017 were $108.1 million, compared to $114.4 million for the first six months of 2016. The approximately $6.3 million decrease during the first six months of 2017, compared to the first six months of 2016, resulted primarily from decreases of approximately $4.1 million for stock-based compensation and $3.6 million for clinical trial expenses, offset by increases of $0.9 million for internal clinical development and $0.7 million for consultants and contractors related expenses.

Second Quarter 2017 Financial Results Compared to Prior Year Period

Total revenues increased $1.9 million, or 4%, over the quarter ended June 30, 2016. Collaboration and licensing revenues increased $0.7 million from the quarter ended June 30, 2016 due to the recognition of deferred revenue associated with the payment received in June 2016 from ZIOPHARM to amend the collaborations between the parties which was partially offset by a decrease in research and development services as the Company temporarily redeployed certain resources towards supporting prospective new platforms and additional collaborations. Product revenues decreased $0.9 million, or 8%, primarily due to a decrease in the quantities of pregnant cows and live calves sold due to lower customer demand for these products. Gross margin on products improved in the current period primarily due to a decline in the average cost of cows. Service revenues increased $2.0 million, or 14%, due to an increase in the number of bovine in vitro fertilization cycles performed due to higher customer demand. Gross margin on services decreased slightly in the current period primarily due to an increase in royalties and commissions due to vendors.

Research and development expenses increased $5.6 million, or 20%, due primarily to increases in (i) salaries, benefits and other personnel costs for research and development employees, (ii) lab supplies and consulting expenses, and (iii) depreciation and amortization. Salaries, benefits and other personnel costs increased $2.2 million due to an increase in research and development headcount to support new, expanded and prospective collaborations, and to support additional platform technology development. Lab supplies and consulting expenses increased $1.7 million as a result of (i) the progression of certain programs into the preclinical and clinical phases with certain of Intrexon’s collaborators, and (ii) the expansion or improvement of certain of the Company’s platform technologies. Depreciation and amortization increased $1.0 million primarily as a result of the amortization of developed technology acquired from Oxitec. Selling, general and administrative (SG&A) expenses increased $8.6 million, or 28%. Salaries, benefits and other personnel costs increased $6.4 million primarily due to (i) increased headcount to support the Company’s expanding operations and (ii) the reversal of previously recognized stock-based compensation expense for departed employees in the quarter ended June 30, 2016. Legal and professional fees increased $1.7 million primarily due to (i) increased legal fees to defend ongoing litigation and (ii) the Company’s acquisition of GenVec that was completed in June 2017.

Total other income (expense), net, increased $40.5 million, or 181%. This increase was primarily attributable to (i) increases in fair market value of the Company’s equity securities portfolio, investments in preferred stock and other convertible instruments and (ii) dividend income from the Company’s investments in preferred stock.

Total revenues increased $12.0 million, or 13%, over the six months ended June 30, 2016. Collaboration and licensing revenues increased $9.7 million from the six months ended June 30, 2016, due to the recognition of deferred revenue associated with the payment received in June 2016 from ZIOPHARM to amend the collaborations between the parties. Product revenues decreased $1.3 million, or 7%, primarily due to a decrease in the quantities of pregnant cows and live calves sold due to lower customer demand for these products. Gross margin on products improved in the current period primarily due to a decline in the average cost of cows. Service revenues increased $3.3 million, or 14%, due to an increase in the number of bovine in vitro fertilization cycles performed due to higher customer demand. Gross margin on services decreased slightly in the current period primarily due to an increase in royalties and commissions due to vendors.

Research and development expenses increased $14.0 million, or 26%, due primarily to increases in (i) salaries, benefits and other personnel costs for research and development employees, (ii) lab supplies and consulting expenses, and (iii) depreciation and amortization. Salaries, benefits and other personnel costs increased $4.7 million due to an increase in research and development headcount to support new, expanded, and prospective collaborations, and to support additional platform technology development. Lab supplies and consulting expenses increased $5.2 million as a result of (i) the progression of certain programs into the preclinical and clinical phases with certain of Intrexon’s collaborators, and (ii) the expansion or improvement of certain of the Company’s platform technologies. Depreciation and amortization increased $2.3 million primarily as a result of the amortization of developed technology acquired from Oxitec. SG&A expenses increased $0.8 million, or 1%. Salaries, benefits and other personnel costs increased $1.5 million primarily due to increased headcount to support the Company’s expanding operations. Legal and professional fees increased $3.9 million primarily due to (i) increased legal fees to defend ongoing litigation and (ii) the Company’s acquisition of GenVec that was completed in June 2017. These increases were offset by $4.2 million in litigation expenses recorded in the prior period arising from the entrance of a court order in Trans Ova Genetics, L.C.’s trial with XY, LLC.

Total other income (expense), net, increased $65.3 million, or 149%. This increase was primarily attributable to (i) increases in fair market value of the Company’s equity securities portfolio, investments in preferred stock and other convertible instruments and (ii) dividend income from the Company’s investments in preferred stock.

Aduro Biotech Bolsters Intellectual Property Position in STING Field with Two New Patents

On August 9, 2017 Aduro Biotech, Inc. (Nasdaq:ADRO), a biopharmaceutical company with three distinct immunotherapy technologies, reported that the United States Patent and Trademark Office has issued two patents to Aduro related to the activation of the STING (Stimulator of Interferon Genes) Pathway (Press release, Aduro Biotech, AUG 9, 2017, View Source [SID1234520129]). The first, U.S. Patent 9,724,408, jointly owned with the University of California and licensed to Aduro Biotech, covers ADU-S100 (MIW815), an investigational STING Pathway Activator being developed as a cancer therapy, and certain methods for its use. The second patent, U.S. Patent 9,695,212, claims methods of using certain additional cyclic dinucleotides (CDNs) to induce STING-dependent immune responses.

"As leaders in cutting edge research and development of STING technologies, it is imperative that we protect our discoveries and expertise related to the modulation of the STING pathway," said Stephen T. Isaacs, chairman, president and CEO of Aduro Biotech. "These issued patents strengthen and broaden the intellectual property coverage for fundamental aspects of our clinical CDN, ADU-S100, in addition to protecting our innovative research recognizing the importance of STING as a central mediator in triggering the development of tumor-specific immunity. We have demonstrated preclinically that activating STING promotes an inflamed tumor phenotype, which led to a profound anti-cancer immune response. ADU-S100 is the first STING Pathway Activator to enter into the clinic and is in an ongoing Phase 1 dose escalation study in patients with cutaneously accessible tumors."

The issued patents bolster our patent portfolio for STING, where Aduro owns and licenses families of patents and patent applications for compounds that target the STING receptor, which would expire, or if issued would expire, between 2025 and 2038. These include both U.S. and international patent applications.

About STING Pathway Activator Platform
The Aduro-proprietary STING pathway activator product candidates, including ADU-S100, are synthetic small molecule immune modulators that are designed to target and activate human STING. STING is generally expressed at high levels in immune cells, including dendritic cells. Once activated, the STING receptor initiates a profound innate immune response through multiple pathways, inducing the expression of a broad profile of cytokines, including interferons and chemokines. This subsequently leads to the development of a systemic tumor antigen-specific T cell adaptive immune response.

Data from preclinical studies using multiple models demonstrated that ADU-S100 activates the STING Pathway and induced a durable local and systemic anti-tumor immune response as evidenced by induction of type I interferons (IFNs) and a CD8+ T-cell response. Additionally, preclinical data showed the combination of STING activation in the tumor microenvironment and PD-1 blockade enhanced antitumor efficacy.

ADU-S100 is currently being evaluated in a Phase 1 dose escalation study in patients with cutaneously accessible tumors. An Investigational New Drug application for the combination of ADU-S100 with an anti-PD-1 immune checkpoint antibody was recently cleared by the U.S. Food and Drug Administration, and the Phase 1b clinical study is expected to begin later in 2017.
