Under the agreement, Almac will develop the NGS diagnostic based on the ArcherDx’s Anchored Multiplex PCR (AMP) chemistry, with the intent of submitting it for regulatory approval in the United States. The companion diagnostic will initially allow Almac’s CLIA-accredited laboratory in Durham, N.C. to identify tumors with the targeted gene fusions, enabling physicians to select appropriate patients for treatment with repotrectinib.

"Almac provides us with deep experience in the development and regulatory approval of next-generation sequencing diagnostic assays, which will enable the selection of patients who may not otherwise have access to a targeted therapy like repotrectinib," said Dr. J Jean Cui, founder, president and chief scientific officer of TP Therapeutics. "We look forward to working with Almac to co-develop repotrectinib with a next generation sequencing based companion diagnostic that detects the presence of ROS1, NTRK1-3 and ALK gene fusions."

"Molecular testing is critical to identifying patients most likely to benefit from a targeted treatment," said Paul Harkin, managing director, Almac Diagnostic Services. "We have great expertise in the development of biomarker assays across a wide range of technologies and targets, with an extensive track-record in developing and validating assays under design control and according to regulatory requirements. We are very pleased to work with TP Therapeutics on such a promising investigational therapy as repotrectinib."

Repotrectinib is an investigational, next-generation tyrosine kinase inhibitor (TKI) developed for the treatment of patients with advanced solid tumors harboring ROS1, NTRK1-3 or ALK molecular rearrangements. Repotrectinib is a rationally designed, low molecular weight, macrocyclic TKI that is much smaller than current ROS1, TRK family and ALK inhibitors with the objective to systematically overcome the clinically acquired resistance mutations of ROS1, TRK family and ALK kinases, especially the gatekeeper and solvent front mutations.

Co-development of CDx and therapeutic products is critical to the advancement of targeted therapies and precision medicine. Companion diagnostics are tests designed to confirm the presence of a specific biomarker to assist physicians in selecting effective therapies for their patients, based on the individual molecular characteristics of each person. Incorporating a companion diagnostic strategy into a drug development program may help generate more effective treatments with improved safety profiles for patients.

The financial terms of the agreement were not disclosed.

Orion and Bayer have completed the phase III trial of darolutamide in patients with non-metastatic castration-resistant prostate cancer – The primary endpoint was met

On October 24, 2018 Orion and Bayer reported that they have completed the phase III clinical trial (ARAMIS) of darolutamide, the novel oral androgen receptor antagonist for the treatment of patients with non-metastatic castration-resistant prostate cancer (nmCRPC) (Press release, Orion Pharma, OCT 24, 2018, View Source;the-primary-endpoint-was-met/ [SID1234530144]). The primary endpoint of the trial was met: Darolutamide significantly extended metastasis-free survival compared to placebo.The safety profile and the tolerability of darolutamide observed in the ARAMIS trial were consistent with previously published data on darolutamide.

The full data will be presented at an upcoming scientific meeting. Bayer plans to discuss the data from the ARAMIS trial with health authorities regarding the submission for marketing authorization application. As a rule, Orion will provide information on the progress of the marketing authorization application process in a press release or in its financial reports. Darolutamide has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA) for the treatment in men with nmCRPC.

The ARAMIS trial

Commenced in 2014, the ARAMIS trial evaluated the efficacy and safety of darolutamide in patients with non-metastatic castration-resistant prostate cancer who are currently being treated with androgen deprivation therapy (ADT) as standard of care and are at risk of developing metastatic disease. In the double-blind, placebo-controlled trial, more than 1,500 patients were randomized to receive 600 mg of darolutamide or matching placebo twice a day. The primary endpoint was metastasis-free survival, defined as time between randomization and evidence of metastasis or death from any cause.

Financial terms

Darolutamide was developed jointly by Orion and Bayer, and the partnership was announced in a stock exchange release on 2 June 2014. Bayer has covered the majority of the darolutamide development costs. According to the agreement, Bayer has the right to commercialize darolutamide globally while Orion has the option of co-promoting the product in Europe. In addition, Orion will manufacture the product for global markets.

Orion is eligible to receive milestone payments from Bayer upon first commercial sale of darolutamide as follows:

EUR 45 million upon first commercial sale in the United States
EUR 20 million upon first commercial sale in the EU
EUR 8 million upon first commercial sale in Japan

Besides milestone payments, Orion will also receive tiered royalties on the product sales, which will be approximately 20 percent, including production revenue. With sales increase, royalties may increase slightly. Orion also has the possibility to receive one-off payments from Bayer if certain sales targets are met.

In addition to the completed ARAMIS trial, Orion and Bayer have an ongoing phase III clinical trial (ARASENS) which evaluates the safety and efficacy of darolutamide in patients with metastatic hormone-sensitive prostate cancer (mHSPC). Expected to be completed in 2022, there are no separate milestone payments related to the ARASENS trial.

"Prostate cancer is the second most commonly diagnosed malignancy in men in worldwide, and approximately 70 percent of patients have the non-metastatic form of the disease. While conventional hormone therapy is effective in the treatment of non-metastatic cancer, the efficacy is often eventually lost as the sole form of treatment. Additional treatment options in the early stages of the cancer that delay the time to metastases with a manageable safety profile are long awaited. They are significant for the patient’s overall well-being," says Christer Nordstedt, Senior Vice President, Research and Development at Orion.

OncoSec Announces Publication of Data in Nature Gene Therapy Demonstrating the Ability of its Newly Optimized Intratumoral IL-12 Immunotherapy Platform to Increase Systemic Anti-tumor Responses in both Treated and Untreated Lesions

On October 24, 2018 OncoSec Medical Incorporated (OncoSec) (NASDAQ:ONCS), a company developing intratumoral cancer immunotherapies, reported the publication of a study in the peer-reviewed journal, Nature Gene Therapy (an open access article; View Source), demonstrating that the newly optimized intratumoral IL-12 immunotherapy platform (electroporation-mediated intratumoral IL-12 gene therapy) induces immunological changes in both locally-treated and distant, untreated tumors (Press release, OncoSec Medical, OCT 24, 2018, View Source [SID1234530143]). The publication provides new mechanistic insights into this systemic anti-tumor immunity including the observation that IL-12 primed effector T cells diminished expression of PD-1, which is particularly relevant to Oncosec’s ongoing KEYNOTE-695 clinical study.

The paper, titled "Characterization of abscopal effects of intratumoral electroporation-mediated IL-12 gene therapy," by Mukhopadhyay et al., reported results from a pre-clinical study of OncoSec’s optimized plasmid IL-12 (TAVO) therapeutic platform on both locally-treated and distant, untreated lesions, with a particular emphasis on understanding "abscopal" effects in distant non-electroporated tumors. Results from the study indicated that intratumoral IL-12 treatment led to an induction of IL-12-regulated genes, other cytokines and chemokines pathways, as well as genes for enhanced antigen processing and presentation in the treated tumor. These localized IL-12-mediated effects then led to the generation of systemic anti-tumor immune responses, including a surge of CD8+ T cells in the spleen and in non-treated tumors and when coupled with PD-1 modulation, suggests an orchestrated "armoring" of these effector T cells against T-cell checkpoints when primed in the presence of IL-12 in situ.

"Data from previously completed clinical and pre-clinical studies of our TAVO platform in multiple cancer settings has clearly demonstrated that our intratumoral electroporation-mediated IL-12 gene therapy is safe and produces systemic anti-tumor effects from a local delivery of this potent cytokine," said Christopher G. Twitty, PhD, Chief Scientific Officer of OncoSec. "Based on these outcomes, OncoSec is advancing an optimized version of TAVO that is designed to increase transgene expression and efficacy. The study published in Gene Therapy indicates that tumors treated directly with the optimized TAVO therapy rapidly engage IL-12/IFN-g regulated pathways, altering the tumor microenvironment’s immunogenicity and effectively creating an in situ vaccine that ultimately drives an increase of tumor infiltrating lymphocytes and immune-specific gene expression in both treated and distant untreated tumors, indicative of a de novo immune response. These results confirm that OncoSec’s TAVO platform may represent a mechanism by which local intratumoral IL-12 gene therapy can deliver a safe and effective abscopal response."

We continue to make significant progress toward our goal of developing medicines for all people with CF as marked by the recent approvals of KALYDECO and ORKAMBI in younger children, the launch of SYMDEKO in the U.S. and the rapid progress we have made with our triple combination pivotal studies," said Jeffrey Leiden, M.D., Ph.D., Chairman, President and Chief Executive Officer of Vertex. "In our development pipeline, we are advancing potential medicines for pain, sickle cell disease and beta thalassemia and are also beginning to advance additional compounds from research into early clinical development that could fundamentally change the treatment of other serious diseases in the future."

Dr. Leiden continued, "Our ability to treat more and more people with CF is driving revenue and earnings growth and significant cash flow generation, which enables the company to invest to discover and develop transformative future medicines for the treatment of CF and other life-threatening diseases."

Combined non-GAAP R&D and SG&A expenses increased compared to the third quarter of 2017 due to the advancement of the company’s portfolio of triple combination regimens for CF and investments to support the treatment of CF globally.
Combined GAAP R&D and SG&A expenses decreased compared to the third quarter of 2017 due to an upfront payment of $160.0 million related to the acquisition of VX-561, an investigational once-daily CFTR potentiator, from Concert Pharmaceuticals in the third quarter of 2017, partially offset by expenses related to the advancement of the company’s portfolio of triple combination regimens for CF and investments to support the treatment of CF globally.

Third-Quarter 2018 Net Income and Cash Position

Non-GAAP net income increased 107% compared to the third quarter of 2017 largely driven by the strong growth in total CF product revenues.
GAAP net income increased compared to the third quarter of 2017 largely driven by the strong growth in total CF product revenues and by a reduction to research and development expenses due to the $160.0 million payment to Concert in the third quarter of 2017.

Cash, cash equivalents and marketable securities as of September 30, 2018 were approximately $3.1 billion, an increase of approximately $1.0 billion compared to $2.1 billion as of December 31, 2017.

2018 Financial Guidance
Vertex today reiterated its full-year 2018 total CF product revenue guidance and guidance for combined GAAP and non-GAAP R&D and SG&A expenses as summarized below:

"We have created a strong financial profile for our business and are poised for continued growth as we make progress developing medicines for many more people with CF," said Ian Smith, Executive Vice President and Chief Operating Officer. "Nearer term, we anticipate revenue growth in 2019 will be driven by the impact of the SYMDEKO and SYMKEVI launches and recently completed reimbursement agreements and label expansions for our CF medicines. The potential for additional revenue growth in 2019 will be dependent upon gaining new reimbursement agreements in key countries, including the UK and France. Continued growth beyond 2019 will be driven by the potential approval, reimbursement and uptake of a triple combination medicine for the large number of patients with a minimal function mutation who currently do not have a treatment for the cause of their CF."

Business Highlights

TRIPLE COMBINATION REGIMENS

Bringing triple combination regimens to people with CF as quickly as possible

Data are expected in late 2018 for the two Phase 3 studies of VX-659 in triple combination with tezacaftor and ivacaftor in people with CF who have one F508del mutation and one minimal function mutation and in people who have two F508del mutations.

Enrollment is expected to be complete in the fourth quarter of 2018 for the two Phase 3 studies of VX-445 in triple combination with tezacaftor and ivacaftor in people with CF who have one F508del mutation and one minimal function mutation and in people who have two F508del mutations. The company plans to report data from these studies in the first quarter of 2019.

Vertex plans to evaluate data from both the VX-659 and VX-445 Phase 3 triple combination programs to choose the best regimen to submit for potential regulatory approval. Together these data are expected to provide the basis for submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for people who have one F508del mutation and one minimal function mutation no later than mid-2019.

Evaluating VX-659 and VX-445 in children

Studies are underway to evaluate both the VX-659 and VX-445 triple combination regimens in children with CF ages 6 through 11 who have one F508del mutation and one minimal function mutation and in children who have two F508del mutations. These studies are intended to support potential approval of a triple combination regimen in children ages 6 through 11.

Potential once-daily regimens

In early 2018, the company reported positive safety and efficacy results for the once-daily potentiator VX-561 when dosed as part of a triple combination regimen including VX-659 or VX-445 and tezacaftor. The once-daily triple combination regimens were generally well tolerated, and the majority of adverse events were mild to moderate.

Based on recent feedback from the FDA, Vertex plans to initiate a Phase 2 study in the first half of 2019 evaluating VX-561 as a monotherapy in people with CF who have a gating mutation.

SYMKEVI in the European Union

On July 27, 2018, Vertex announced that the European Medicines Agency (EMA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion for SYMKEVI (tezacaftor/ivacaftor) in a combination regimen with ivacaftor (KALYDECO) for the treatment of people with CF ages 12 and older who either have two copies of the F508del mutation or who have one copy of the F508del mutation and a copy of one of the following 14 mutations in which the CFTR protein shows residual activity: P67L, R117C, L206W, R352Q, A455E, D579G, 711+3A→G, S945L, S977F, R1070W, D1152H, 2789+5G→A, 3272-26A→G, and 3849+10kbC→T.

Approval for SYMKEVI in the European Union (EU) is expected in the fourth quarter of 2018.

APPROVED CF MEDICINES
Establishing long-term reimbursement outside of the U.S.

On October 1, 2018, Vertex announced that it had entered into an innovative access contract with the Danish pharmaceutical and procurement organization, Amgros. This agreement provides eligible Danish CF patients access to all of Vertex’s current and future CF medicines. An agreement in Austria was also recently secured to provide access to ORKAMBI for all people with CF ages 6 through 11 who have two copies of the F508del mutation.

In September 2018, Vertex announced a reimbursement agreement in Australia for the use of ORKAMBI in people with CF ages 6 and older who have two copies of F508del mutation. A pathway to access for future Vertex CF medicine, tezacaftor/ivacaftor, was also established as part of this process.

Treating patients at younger ages with CFTR modulators: The company continues to make significant progress toward gaining approval for its CF medicines to be used earlier in the course of disease progression. Recent highlights include:

Vertex plans to submit a supplemental New Drug Application (sNDA) to the FDA in late 2018 based on positive data from a recently completed 24-week single-arm Phase 3 safety study of tezacaftor/ivacaftor in 70 children ages 6 through 11 who have two copies of the F508del mutation or who have one copy of the F508del mutation and one residual function mutation. The primary endpoint of the study was safety. The study met its primary safety endpoint, and safety data from the study showed that the treatment was generally well tolerated and safety data were consistent with those seen in previous Phase 3 studies of tezacaftor/ivacaftor in children ages 12 and older. To support approval in the EU, an eight-week, double-blind, placebo-controlled Phase 3 efficacy study is ongoing to evaluate tezacaftor/ivacaftor in approximately 65 children ages 6 through 11. The primary endpoint of this study is the absolute change in lung clearance index.

KALYDECO was approved in August 2018 in the U.S. for children with CF ages 12 to <24 months. On October 19, 2018, Vertex announced that it received a positive opinion from the European CHMP for KALYDECO in this age group. The company expects a decision in the EU in late 2018.

On October 18, 2018, Vertex announced positive data from a Phase 3 study evaluating ivacaftor in infants ages 6 to <12 months. These are the first data to demonstrate the potential to treat the underlying cause of CF in patients as young as six months old. The company plans to submit an sNDA to the FDA and a line extension to the EMA in late 2018.

ORKAMBI was approved in August 2018 in the U.S. for children with CF ages 2 to 5 years old. A line extension has been submitted to the EMA with a decision anticipated in the first half of 2019.

Dosing is underway in Phase 3 study evaluating lumacaftor/ivacaftor in children ages 12 to <24 months.

LATE-STAGE RESEARCH & CLINICAL DEVELOPMENT

Vertex continues to invest to discover and develop transformative medicines in other serious diseases. The company has a portfolio of potential medicines across a range of diseases, including:

Sickle Cell Disease & β-Thalassemia: Vertex and its partner CRISPR Therapeutics are developing the autologous gene-edited hematopoietic stem cell therapy CTX001 for the treatment of β-thalassemia and sickle cell disease.

In the U.S., Vertex and CRISPR Therapeutics recently announced that the FDA lifted the clinical hold on the CTX001 Investigational New Drug application (IND) for the treatment of sickle cell disease that was submitted earlier this year. The companies previously received regulatory approval to conduct a Phase 1/2 study in multiple countries in Europe and Canada. Vertex and CRISPR plan to initiate the study in sickle cell disease by the end of 2018. The first two patients in the study will be dosed sequentially and, pending data from these initial two patients, subsequent patients can be dosed concurrently.

Enrollment for a Phase 1/2 study in people with β-thalassemia is currently open at multiple clinical trial sites in Europe, and the first patient has now enrolled in this study. The Phase 1/2 trial is designed to assess safety and efficacy in adult transfusion-dependent non-beta zero/beta zero β-thalassemia patients. Similar to the study in sickle cell disease, the first two patients in the study will be dosed sequentially and, pending data from these initial two patients, subsequent patients can be dosed concurrently. This study is designed to enroll up to 45 patients.

Pain: Potential Role of Nav1.8 Inhibition

The company is planning to initiate a Phase 2b dose-ranging study evaluating the Nav1.8 inhibitor VX-150 using an oral formulation in patients with acute pain following bunionectomy surgery. The study is designed to evaluate multiple oral doses of VX-150 to potentially support pivotal development in acute pain.

Enrollment is complete in a Phase 2 proof-of-concept study evaluating VX-150 for the treatment of pain caused by small fiber neuropathy, and data are expected in early 2019.

Vertex continues to invest to discover other potential pain molecules that target the sodium channel 1.8 (Nav1.8) and other new mechanisms.

Alpha-1 Antitrypsin Deficiency (AAT)
•Vertex has advanced multiple small molecule correctors of AAT through preclinical development and is preparing to initiate clinical development for the first of these potential medicines by the end of 2018. AAT is a genetic disorder that is caused by mutations in a single gene that result in life-shortening systemic complications, primarily in the lung and liver.

Acute Spinal Cord Injury

In October 2014, VRTX in-licensed VX-210 (Cethrin) from BioAxone BioSciences, Inc. as a potential new treatment for spinal cord injury. An interim analysis of a Phase 2b study evaluating VX-210 in patients with certain acute cervical spinal cord injuries was recently conducted and based on the available data, the study’s Data Safety Monitoring Board (DSMB) recommended to stop the study early due to futility. There were no safety concerns noted in the DSMB’s review of the data. Based on the DSMB’s recommendation and Vertex’s review of the data, the company has decided to stop all development of VX-210, and will terminate the Phase 2b study. Vertex will discuss with BioAxone the next steps for the program.

Sarepta Therapeutics Announces Third Quarter 2018 Financial Results and Recent Corporate Developments

Nationwide Children’s Hospital Gene Therapy Partnership, Charcot-Marie-Tooth (CMT) Neuropathy – Forged another agreement with Nationwide Children’s Hospital giving Sarepta the certain exclusive rights to the Nationwide Children’s gene therapy candidate, neurotrophin 3 (NT-3), to treat CMT neuropathies, including CMT type 1A. CMT is a group of hereditary, degenerative nerve diseases that can affect motor skills, resulting in muscle weakness, and limiting patients’ ability to walk or use their hands. CMT is the most common inherited neuromuscular disorder, affecting over 2.8 million people worldwide. A clinical trial is scheduled to begin in 2019 in the most prevalent subtype of CMT, CMT type 1A.

Positive Micro-Dystrophin Gene Therapy Clinical Results in DMD Patients Presented at the 23rd International Congress of the World Muscle Society (Mendoza, Argentina) – Jerry Mendell, M.D., of Nationwide Children’s, presented positive updated results from the gene therapy clinical trial assessing AAVrh74.MHCK7.micro-Dystrophin in individuals with Duchenne muscular dystrophy (DMD). Dr. Mendell’s presentation included positive results from the biopsy of the fourth patient showing robust micro-dystrophin expression as measured by Western blot and immunohistochemistry. In all patients, expression of micro-dystrophin was associated with significant expression and up regulation of the dystrophin-associated protein complex, an additional indication of functionality of dystrophin. All patients showed significant decreases of serum creatine kinase (CK) levels at last measure versus baseline, and positive functional improvements were shown across all measures. No serious adverse events (SAEs) were observed.

Clinical Hold Lifted for DMD Micro-dystrophin Gene Therapy Program – The Food and Drug Administration (FDA) lifted the clinical hold for Sarepta’s DMD micro-dystrophin gene therapy program. Sarepta previously announced on July 25, 2018 that the FDA placed the program on clinical hold due to the presence of trace amounts of DNA fragment in research-grade third-party supplied plasmid in a manufacturing lot. In response, and in collaboration with Nationwide Children’s, an action plan was developed and submitted to the FDA, including an audit of the plasmid supplier and a commitment to use GMP-s plasmid for all future production lots.

Research and development expenses were $86.6 million for the third quarter of 2018, compared to $34.2 million for the same period of 2017, an increase of $52.4 million. The increase in research and development expenses primarily reflects the following:

$18.0 million increase in up-front and milestone payments. The Company made a milestone payment of $10.0 million to Myonexus Therapeutics (Myonexus) for the achievement of one of the development milestones. In addition, the Company expensed $8.0 million related to the purchase of license to develop, manufacture and commercialize a pre-clinical Pompe product candidate under a license agreement with Lacerta Therapeutics (Lacerta);

$12.8 million increase in clinical and manufacturing expenses primarily due to increased patient enrollment in the on-going ESSENCE trial as well as a ramp-up of manufacturing activities for golodirsen, our micro-dystrophin program and our PPMO platform. These increases were partially offset by a ramp-down of clinical trials in eteplirsen primarily because the PROMOVI trial has been fully enrolled;

$8.1 million increase in compensation and other personnel expenses primarily due to an increase in headcount;

$3.8 million increase in pre-clinical expenses primarily due to the continuing ramp-up of toxicology studies in our PPMO platform;

Exhibit 99.1

$2.6 million increase in facility-related expenses due to our continuing expansion efforts;

$2.6 million increase in sponsored research with institutions such as Duke University and Nationwide Children’s Hospital;

$1.6 million increase in collaboration cost sharing with Summit on its utrophin platform; and

$1.4 million increase in stock-based compensation expense primarily driven by increases in headcount and stock price.

Research and development expenses were $255.6 million for the nine months ended September 30, 2018, compared to $122.3 million for the same period of 2017, an increase of $133.3 million. The increase in research and development expenses primarily reflects the following:

$56.0 million increase in up-front and milestone payments. The Company made an up-front payment of $60.0 million to Myonexus upon execution of the warrant to purchase common stock agreement in May 2018 and a milestone payment of $10.0 million to Myonexus upon achievement of one of the development milestones in September 2018. In addition, the Company expensed $8.0 million related to the purchase of license to develop, manufacture and commercialize a pre-clinical Pompe product candidate under a license agreement with Lacerta. In May 2017, the Company made a milestone payment of $22.0 million to Summit as the milestone of the last patient dosed in the safety arm cohort to the PhaseOut DMD study was achieved;

$25.0 million increase in clinical and manufacturing expenses primarily due to increased patient enrollment in the on-going ESSENCE trial as well as a ramp-up of manufacturing activities for golodirsen, casimersen, our micro-dystrophin program and our PPMO platform. These increases were partially offset by a ramp-down of clinical trials in eteplirsen primarily because the PROMOVI trial has been fully enrolled;

$16.7 million increase in compensation and other personnel expenses primarily due to an increase in headcount;

$7.9 million increase in pre-clinical expenses primarily due to the continuing ramp-up of toxicology studies in our PPMO platform as well as golodirsen and casimersen;

$7.6 million increase in collaboration cost sharing with Summit on its utrophin platform;
rimarily due to continuing accelerated company growth as a result of expansion of our R&D pipeline;

$4.5 million increase in stock-based compensation expense primarily driven by increases in headcount and stock price as well as achievement of a milestone related to the September 2016 restricted stock awards with a performance condition; and $4.0 million increase in sponsored research with institutions such as Duke University, Genethon and Nationwide Children’s Hospital.

Non-GAAP research and development expenses were $64.2 million and $31.5 million for the third quarter of 2018 and 2017, respectively. Non-GAAP research and development expenses were $164.5 million and $92.2 million for the nine months ended September 30, 2018 and 2017, respectively.

Selling, general and administration

Selling general and administrative expenses were $53.0 million for the third quarter of 2018, compared to $28.2 million for the same period of 2017, an increase of $24.8 million. The increase in selling, general and administrative expenses primarily reflects the following:

$9.8 million and $1.7 million increase in professional services and facility-related expenses, respectively, primarily due to continuing global expansion;

$9.4 million increase in compensation and other personnel expenses primarily due to an increase in headcount; and

$3.0 million increase in stock-based compensation primarily due to increases in headcount and stock price.

Selling general and administrative expenses were $143.5 million for the nine months ended September 30, 2018, compared to $90.5 million for the same period of 2017, an increase of $53.0 million. The increase in selling, general and administrative expenses primarily reflects the following:

EXONDYS 51 litigation and license charges

As a result of the execution of the settlement and license agreements with BioMarin in July 2017, the Company recognized litigation and license charges of $25.6 million and $28.4 million during the three and nine months ended September 30, 2017, respectively. There was no such a transaction in 2018.

Amortization of in-licensed rights

For the three and nine months ended September 30, 2018, the Company recorded amortization of in-licensed rights of approximately $0.2 million and $0.6 million, respectively. For both the three and nine months ended September 30, 2017, the Company recorded amortization of in-licensed rights of approximately $0.8 million.

Other (loss) income

Gain from sale of Priority Review Voucher

In connection with the completion of the sale of the Priority Review Voucher (PRV) in March 2017, the Company recorded a gain of $125.0 from sale of the PRV in the first quarter of 2017.

Interest (expense) income and other, net

For the three and nine months ended September 30, 2018, the Company recorded $7.0 million and $16.7 million, respectively, of interest expense and other, net. For the same periods of 2017, the Company recorded $0.2 million and $0.7 million, respectively, of interest income and other, net. The period over period unfavorable change primarily reflects the interest expense accrued on the convertible notes issued in November 2017 partially offset by interest income from higher balances of cash, cash equivalents and investments.

Cash, Cash Equivalents, Investments and Restricted Investment

Exhibit 99.1

The Company had approximately $793.9 million in cash, cash equivalents and investments as of September 30, 2018 compared to $1.1 billion as of December 31, 2017. The decrease is primarily driven by the use of cash to fund the Company’s ongoing operations during the first three quarters of 2018.

Use of Non-GAAP Measures

In addition to the GAAP financial measures set forth in this press release, the Company has included certain non-GAAP measurements. The non-GAAP loss is defined by the Company as GAAP net loss excluding interest expense/(income), income tax expense/(benefit), depreciation and amortization expense, stock-based compensation expense, restructuring expense and other items. Non-GAAP research and development expenses are defined by the Company as GAAP research and development expenses excluding depreciation and amortization expense, stock-based compensation expense, restructuring expense and other items. Non-GAAP selling, general and administrative expenses are defined by the Company as GAAP selling, general and administrative expenses excluding depreciation and amortization expense, stock-based compensation expense, restructuring expense and other items.

1. Interest, tax, depreciation and amortization

Interest income and expense amounts can vary substantially from period to period due to changes in cash and debt balances and interest rates driven by market conditions outside of the Company’s operations. Tax amounts can vary substantially from period to period due to tax adjustments that are not directly related to underlying operating performance. Depreciation expense can vary substantially from period to period as the purchases of property and equipment may vary significantly from period to period and without any direct correlation to the Company’s operating performance. Amortization expense associated with in-licensed rights as well as patent costs are amortized over a period of several years after acquisition or patent application or renewal and generally cannot be changed or influenced by management.

2. Stock-based compensation expenses

Stock-based compensation expenses represent non-cash charges related to equity awards granted by Sarepta. Although these are recurring charges to operations, management believes the measurement of these amounts can vary substantially from period to period and depend significantly on factors that are not a direct consequence of operating performance that is within management’s control. Therefore, management believes that excluding these charges facilitates comparisons of the Company’s operational performance in different periods.

Exhibit 99.1

3. Restructuring expenses

The Company believes that adjusting for these items more closely represents the Company’s ongoing operating performance and financial results.

4. Other items

The Company evaluates other items of expense and income on an individual basis. It takes into consideration quantitative and qualitative characteristics of each item, including (a) nature, (b) whether the items relates to the Company’s ongoing business operations, and (c) whether the Company expects the items to continue on a regular basis. These other items include the aforementioned gain from the sale of the Company’s PRV and up-front and milestone payments.

The Company uses these non-GAAP measures as key performance measures for the purpose of evaluating operational performance and cash requirements internally. The Company also believes these non-GAAP measures increase comparability of period-to-period results and are useful to investors as they provide a similar basis for evaluating the Company’s performance as is applied by management. These non-GAAP measures are not intended to be considered in isolation or to replace the presentation of the Company’s financial results in accordance with GAAP. Use of the terms non-GAAP research and development expenses, non-GAAP selling, general and administrative expenses, non-GAAP other income and loss adjustments, non-GAAP income tax expense, non-GAAP net loss, and non-GAAP basic and diluted net loss per share may differ from similar measures reported by other companies, which may limit comparability, and are not based on any comprehensive set of accounting rules or principles. All relevant non-GAAP measures are reconciled from their respective GAAP measures in the attached table "Reconciliation of GAAP Financial Measures to Non-GAAP Financial Measures."

About EXONDYS 51

EXONDYS 51 uses Sarepta’s proprietary phosphorodiamidate morpholino oligomer (PMO) chemistry and exon-skipping technology to skip exon 51 of the dystrophin gene. EXONDYS 51 is designed to bind to exon 51 of dystrophin pre-mRNA, resulting in exclusion of this exon during mRNA processing in patients with genetic mutations that are amenable to exon 51 skipping. Exon skipping is intended to allow for production of an internally truncated dystrophin protein.

Important Safety Information About EXONDYS 51

Exhibit 99.1

Hypersensitivity reactions, including rash and urticaria, pyrexia, flushing, cough, dyspnea, bronchospasm, and hypotension, have occurred in patients who were treated with EXONDYS 51. If a hypersensitivity reaction occurs, institute appropriate medical treatment and consider slowing the infusion or interrupting the EXONDYS 51 therapy.

Adverse reactions in DMD patients (N=8) treated with EXONDYS 51 30 or 50 mg/kg/week by intravenous (IV) infusion with an incidence of at least 25% more than placebo (N=4) (Study 1, 24 weeks) were (EXONDYS 51, placebo): balance disorder (38%, 0%), vomiting (38%, 0%) and contact dermatitis (25%, 0%). The most common adverse reactions were balance disorder and vomiting. Because of the small numbers of patients, these represent crude frequencies that may not reflect the frequencies observed in practice. The 50 mg/kg once weekly dosing regimen of EXONDYS 51 is not recommended.

In the 88 patients who received ≥30 mg/kg/week of EXONDYS 51 for up to 208 weeks in clinical studies, the following events were reported in ≥10% of patients and occurred more frequently than on the same dose in Study 1: vomiting, contusion, excoriation, arthralgia, rash, catheter site pain, and upper respiratory tract infection.
