November 6, 2017

Boston, MA - Flex Pharma, Inc. (NASDAQ: FLKS), a clinical-stage biotechnology company that is developing innovative and proprietary treatments in Phase 2 randomized, controlled trials for cramps and spasticity associated with severe neurological diseases such as multiple sclerosis (MS), Charcot-Marie-Tooth (CMT) and amyotrophic lateral sclerosis (ALS) under FDA Fast Track designation, today reported financial results for the quarter ended September 30, 2017 and provided an update on its clinical development and corporate activities.

“We are encouraged by the consistently positive impact of FLX-787 across multiple efficacy endpoints related to cramping and the associated pain from our small, exploratory Phase 2 trial in Australian ALS patients that provides the first clinical evidence of effect for our lead candidate in patients with underlying neurological disease. Our development programs are steadily advancing. We have initiated our Phase 2b ALS trial under Fast Track designation, and, more recently, our Phase 2b CMT trial. These two studies, as well as the ongoing exploratory spasticity study in MS in Australia, are expected to yield several important data readouts in 2018,” stated Dr. William McVicar, President and CEO of Flex Pharma. “I am also excited to begin testing potential new applications of our chemical neurostimulation technology to address dysphagia, or difficulty swallowing, in ALS, in addition to cramping in renal failure patients during or between dialysis sessions. We expect to begin studying these indications in the next six months.”

Recent Business Highlights

Clinical Efforts
In November, the Company announced positive topline data for FLX-787 from its Australian ALS trial of patients who cramp frequently. In the 8 patients who completed the trial per protocol, FLX-787 demonstrated a statistically significant percentage reduction from baseline in both cramp-associated pain intensity (p<0.05) and stiffness (p<0.05), relative to placebo control, based on Numerical Rating Scales (NRS). Strong and consistent trends were demonstrated on multiple endpoints, including: percentage reduction in the number of cramps from baseline (p=0.08), increase in cramp free days from baseline (p=0.09), and improvements on both Patient (PGIC; p=0.06) and Clinician (CGIC; p=0.06) Global Impression of Change. FLX-787 was generally well tolerated in





all patients. In July 2017, the Company announced that it had stopped this study after 12 patients were randomized.

In October, the Company initiated a Phase 2b randomized, controlled, double-blinded, parallel design trial in the US, referred to as the COMMIT trial. The COMMIT trial will evaluate FLX-787, the Company’s co-activator of TRPA1 and TRPV1, in patients with Charcot-Marie-Tooth, who suffer from painful, debilitating cramps. The Company expects to report topline results from this study in the third quarter of 2018.

In August, the Company initiated its Phase 2b randomized, controlled, double-blinded, parallel design trial in the US, referred to as the COMMEND trial, to evaluate FLX-787, the Company’s co-activator of TRPA1 and TRPV1, in patients with motor neuron disease (MND), focused on ALS, who suffer from cramps. The Company expects to report topline results from this study in the third quarter of 2018.

In July, the Company announced that the Food and Drug Administration (FDA) granted Fast Track Designation for the development of FLX-787 to treat severe muscle cramps in patients with ALS. There are currently no drugs approved in the US for this condition. Fast Track Designation is intended to accelerate the clinical development and review of drugs to treat serious conditions that address an unmet medical need.

Consumer Business
For the quarter ended September 30, 2017, the Company recorded approximately $414,000 in total revenue for its consumer product, HOTSHOT®, launched in June 2016. The Company expects full year revenues for 2017 to exceed 2016.

Strengthened Leadership Team
In October, Flex Pharma announced that Roger Tung, Ph.D. was appointed to its Board of Directors. Dr. Tung is the scientific co-founder of Concert Pharmaceuticals, where he serves as President and CEO. Prior to Concert, Dr. Tung was a founding scientist at Vertex. Dr. Tung has more than 30 years of experience in the global biopharmaceutical industry.

In July, Flex Pharma’s Board of Directors appointed William McVicar, Ph.D., as President and CEO. Dr. McVicar brings approximately 30 years of clinical development experience to the Company, formerly serving as the Company’s President of Research and Development. In June, Christoph Westphal, M.D., Ph.D., transitioned from his role as CEO and continues to serve on Flex Pharma's Board. Prior to joining Flex Pharma, Dr. McVicar served as Executive Vice President of Pharmaceutical Development, Chief Scientific Officer, and President during his tenure at Inotek. As Vice President of Development Operations at Sepracor, he oversaw the development, FDA review, and approval of multiple NDAs and SNDAs, including BROVANA®, XOPENEX MDI®, and XOPENEX’s pediatric approval, which were each approved in a single 10-month review cycle. Prior to Sepracor, Dr. McVicar held various positions of increasing responsibility at Sandoz, Novartis and Rhone Poulenc Rorer.

Third Quarter 2017 Financial Results






Cash Position: As of September 30, 2017, Flex Pharma had cash, cash equivalents and marketable securities of $38.9 million. During the three months ended September 30, 2017, cash, cash equivalents and marketable securities decreased by $8.2 million.

Total Revenue: Total revenue for the three months ended September 30, 2017 was approximately $414,000, including approximately $7,000 of other revenue.

Cost of Product Revenue: Cost of product revenue for the three months ended September 30, 2017 was approximately $149,000.

R&D Expense: Research and development expense for the three months ended September 30, 2017 was $4.7 million. Research and development expense for this quarter primarily included costs associated with the Company’s clinical studies of FLX-787, personnel costs (including salaries and stock-based compensation costs), FLX-787 production costs and external consultant costs.

SG&A Expense: Selling, general and administrative expense for the three months ended September 30, 2017 was $4.9 million. Selling, general and administrative expense for this quarter primarily included personnel costs (including salaries and stock-based compensation costs), sales, marketing and fulfillment costs related to HOTSHOT, legal and professional costs and external consultant costs.

Net Loss and Cash Flow: Net loss for the three months ended September 30, 2017 was ($9.3) million, or ($0.54) per share and included $1.0 million of stock-based compensation expense. As of September 30, 2017, Flex Pharma had 17,541,377 shares of common stock outstanding, which excludes approximately 0.4 million shares of stock that remain subject to vesting. The net loss for the third quarter of 2017 was primarily driven by the Company’s operating expenses related to its research and development efforts, costs associated with HOTSHOT, and general and administrative costs.

Financial Guidance
Based on its current operating plans and cash, cash equivalents and marketable securities position, Flex Pharma expects to have sufficient capital to fund its operations into early 2019.

November 6, 2017
 
Boston, MA - Flex Pharma, Inc. (NASDAQ: FLKS), a clinical-stage biotechnology company that is developing innovative and proprietary treatments in Phase 2 randomized, controlled trials for cramps and spasticity associated with severe neurological diseases such as multiple sclerosis (MS), Charcot-Marie-Tooth (CMT) and amyotrophic lateral sclerosis (ALS) under FDA Fast Track designation, today announced positive topline data for FLX-787 from its randomized, double-blinded, placebo-controlled, cross-over Australian trial in ALS patients with frequent muscle cramps. The study was terminated early to focus the Company’s resources on the ongoing US Phase 2b ALS study (COMMEND).

“We are encouraged by the consistently positive impact of FLX-787 across multiple efficacy endpoints related to cramping and the associated pain, despite the small number of patients completing the study,” said Dr. William McVicar, Flex Pharma President and CEO. “These data demonstrate the potential for FLX-787 to benefit ALS patients who suffer from frequent cramping in our ongoing Phase 2b trial, the COMMEND study. With data readouts in MS, ALS, and CMT expected over the next year, we are excited to advance the development of FLX-787, under Fast Track designation for ALS-associated cramping.”

In eight patients who completed the trial per protocol, FLX-787 demonstrated a statistically significant (p<0.05) percentage reduction from baseline in both cramp-associated pain intensity and stiffness, relative to placebo control, based on daily patient assessments by Numerical Rating Scale (NRS). Strong and consistent trends were demonstrated on multiple endpoints, including: percentage reduction in the number of cramps from baseline (p=0.08), increase in cramp free days from baseline (p=0.09), and improvements on both the Patient (PGIC; p=0.06) and Clinician (CGIC; p=0.06) Global Impression of Change. FLX-787 was generally well tolerated.

In the patients completing both cross-over periods per protocol:

FLX-787 showed a median 31% reduction in cramps from baseline versus 0.1% reduction for patients while on placebo control;
Patients had a median of 4.4 cramp free days versus 0 for placebo control;
Patients evaluated themselves as improved with FLX-787 treatment 50% of the time versus 12.5% with placebo control (PGIC); and
Clinicians blinded to treatments evaluated 50% of patients as improved with FLX-787 versus 0% for placebo control (CGIC).

The Company also analyzed the Period 1 and Period 2 results of all patients randomized in the





trial and believes the cross-over results are not driven by a cross-over bias or unblinding effect.

“Nearly all ALS patients report cramps and the majority seek treatment to relieve their suffering from painful cramping and yet there are no approved therapies in the US. This data set provides the first clinical evidence that FLX-787 has an effect in patients with underlying neurological disease and demonstrates the utility of chemical neurostimulation in treating symptoms arising from motor neuron hyperexcitability,” said Flex Pharma Chief Medical Officer Thomas Wessel, M.D., Ph.D. “In prior studies, FLX-787 has demonstrated similar efficacy profiles in individuals with normally functioning nervous systems such as those suffering from nocturnal leg cramps and healthy normal volunteers studied in our electrically-induced cramp model.”

Data from this study outlined above will be presented at future medical meetings.

Phase 2 Trial Design

This randomized, blinded, placebo-controlled Phase 2 clinical trial, had originally planned to enroll up to 60 subjects with ALS or primary lateral sclerosis (PLS) patients with frequent muscle cramps in Australia. Due to the challenge of enrolling ALS patients from a limited population in Australia, and a greater priority placed on the completion of the larger US Phase 2b trial, the Company announced in July 2017 that we stopped the trial after 12 patients were randomized. Of these, 8 patients completed both cross-over periods and received both FLX-787 and the placebo control. Patients were given 19 mg of FLX-787, formulated as an orally disintegrating tablet (ODT) or placebo control, two or three times daily. The trial included a 14-day run-in period with no treatment to establish baseline characteristics, followed by treatment periods during which patients received FLX-787 or placebo in the first 14-day treatment period before “crossing-over” to the other treatment for an additional 14-day treatment period. The exploratory study was designed to evaluate a number of endpoints relating to cramping frequency, cramp-associated pain, spasticity, stiffness, global impression of change by the patient and the clinician, quality of life, sleep and safety. Eight patients completed both crossover conditions and were included in the primary per protocol analysis.

About the COMMEND Clinical Trial

The COMMEND trial is an ongoing Phase 2b clinical trial designed to evaluate FLX-787 in patients with motor neuron disease (MND), focused on ALS, who suffer from cramps. This randomized, controlled, double-blinded, parallel design trial in the US includes a 28-day run-in period to establish a baseline in cramp frequency. Patients are then randomized to 30 mg of FLX-787 administered three times a day, or control, for 28 days. Patients will be evaluated for changes in cramp frequency as the primary endpoint, with a number of secondary endpoints, including the PGIC, CGIC, cramp-related pain and spasticity.

Details of this trial can be found at clinicaltrials.gov.

Terminated early to focus resources on larger Phase 2b US trial • Orally Disintegrating Tablet (ODT) of 19 mg FLX-787 (spicy) or Placebo (sweet) Inclusion Criteria: 1. Diagnosed with Amyotrophic Lateral Sclerosis (ALS) or Progressive Lateral Sclerosis (PLS) for at least 1 month 2. > 12 cramps per month (approximately 3 per week) 3. Spasticity of at least 3 months duration that is not completely relieved by current therapy


 
4 • FLX-787 treatment was associated with improvements in cramping and related symptoms, from pre-treatment baselines, including: - Decreased Pain Intensity (NRS) associated with most painful cramp (p<0.05) - Decreased Stiffness (NRS) (p<0.05) - Greater Percentage Reduction of Cramps from baseline (~30% decrease) (p=0.08) - Increased Number of Cramp Free Days (p=0.09) - Improved Patient (p=0.06) and Clinician (p=0.06) Global Impression of Change • These data, the first in patients with serious neurological disease, indicate the potential of FLX-787 to alleviate cramps and cramp-related symptoms. • 19 mg FLX-787 (BID or TID) were generally well tolerated in subjects with MND. No drug-related SAEs or discontinuations were reported. A few GI-related AEs (abdominal pain, diarrhea) were reported with FLX-787. • The comparison of Period 1 and Period 2 results suggest the cross-over results are not driven by a cross-over bias or unblinding effect. (see appendix) • Results confirm the potential of the ongoing 100 subject, parallel design, ALS trial with 4 weeks of run-in and treatment, utilizing a more robust 30 mg TID dose. FLX-787 Reduces Pain from Cramping (p<0.05) and Associated Stiffness (p<0.05) in ALS Patients Statistically significant improvements Improvements approaching statistical significance
