Zynerba Pharmaceuticals Announces Twelve Month ZYN002 Data from STAR 2 Study in Patients with Focal Seizures at the 2018 Annual Meeting of the American Academy of Neurology (AAN)

Continued Improvement in Seizure Control Seen in Adult Refractory Focal Seizure Patients Receiving ZYN002 through 12 Months of Open Label Exposure

In a poster presentation entitled, “Transdermal Cannabidiol (CBD) Gel for the Treatment of Focal Epilepsy in Adults” (poster P4.468), Dr. John Messenheimer presents additional data from ongoing STAR 2 (Synthetic Transdermal CAnnabidiol for the TReatment of Epilepsy) 24-month open label extension study evaluating ZYN002 cannabidiol (CBD) transdermal gel in adult patients with focal seizures. The presentation includes data through twelve months of open label exposure to ZYN002.Los Angeles, CA, April 25, 2018 — Zynerba Pharmaceuticals, Inc. (NASDAQ:ZYNE), a clinical-stage specialty neuropsychiatric pharmaceutical company dedicated to developing and commercializing innovative pharmaceutically-produced transdermal cannabinoid treatments for rare and near-rare neurological and psychiatric disorders with high unmet medical needs, is reporting new longer term open label clinical data today in the Emerging Science session of the 2018 Annual Meeting of the American Academy of Neurology (AAN) in Los Angeles, CA.

The key findings include that responses to ZYN002 in the STAR 2 open label extension, as measured by reductions in focal seizures from the baseline period of STAR 1, are associated with continued treatment with ZYN002. In addition, ZYN002 was shown to be well tolerated through 12 months of treatment in STAR 2.

“These data continue to suggest that focal seizures may be reduced with longer-term exposure to transdermally-delivered CBD,” said Dr. Liza Squires, Zynerba’s Chief Medical Officer. “In this population of patients, the use of ZYN002 for an additional 12 months in STAR 2 was well tolerated and appeared to result in clinically meaningful seizure reductions both across and within the originally randomized STAR 1 groups. These data continue to provide insight into the potential for ZYN002 in certain epilepsies, and we look forward to initiating a Phase 2b study in adult refractory focal seizures in the second half of 2018.”

The data presented in the poster are as follows:

  • 188 patients were randomized, 186 were analyzed for efficacy, and 174 completed STAR 1;
  • 171 patients (98% of STAR 1 completers) continued into STAR 2;
  • As of December 12, 2017, 95 patients remained in the STAR 2 study;
  • Patients were taking a wide range of antiepileptic drugs (AEDs), the most common of which are levetiracetam, carbamazepine, lamotrigine, lacosamide, and valproate.

Efficacy

  • In STAR 2, longer term exposure to ZYN002 resulted in greater improvements in seizure frequency among all ZYN002-treated patients;
  • Longer term exposure to ZYN002 appeared to result in clinically meaningful reductions in seizures both across and within originally randomized STAR 1 patient groups:
    – Compared to baseline, the median changes in seizure rates at months 3, 6, 9, and 12 of STAR 2 across all ZYN002-treated patients at each time point were:
    — 25% reduction at month 3 (N=171)
    — 36% reduction at month 6 (N=146)
    — 49% reduction at month 9 (N=112)
    — 58% reduction at month 12 (N=70)


– Compared to baseline, the median changes in seizure rates at months 3, 6, 9, and 12 of STAR 2 in patients initially treated with placebo or ZYN002 in STAR 1 were:

Median Change (%) in Seizure Rates in STAR 2 Study
Month 3 Month 6 Month 9 Month 12
Placebo (STAR 1) -10 (n=60) -16 (n=49) -41 (n=37) -57 (n=24)
ZYN002 195 mg (STAR 1) -32 (n=56) -48 (n=49) -55 (n=39) -63 (n=25)
ZYN002 390 mg (STAR 1) -31 (n=55) -38 (n=48) -46 (n=36) -59 (n=21)

Safety

  • ZYN002 was well tolerated with good skin tolerability;
  • In STAR 2, the most common treatment-emergent AEs (> 7.5%) were upper respiratory tract infection (viral and bacterial [17%]) and headache (11%);
  • One serious AE was considered possibly related to ZYN002 (increased anxiety);
  • There were no clinically significant abnormal liver AEs (i.e. alanine aminotransferase/aspartate aminotransferase) >3x upper limit of normal reported for patients receiving ZYN002.

Zynerba Pharmaceuticals Initiates Open-Label Phase 2 Trial of ZYN002 in Developmental and Epileptic Encephalopathies (DEE)

Devon, PA, April 10, 2018 — Zynerba Pharmaceuticals, Inc. (NASDAQ:ZYNE), a clinical-stage specialty neuropsychiatric pharmaceutical company dedicated to developing and commercializing innovative pharmaceutically-produced transdermal cannabinoid treatments for rare and near-rare neurological and psychiatric disorders with high unmet medical needs, today announced that it has initiated the Phase 2 BELIEVE 1 (Open Label Study to Assess the Safety and Efficacy of ZYN002 Administered as a Transdermal Gel to Children and Adolescents with Developmental and Epileptic Encephalopathy) clinical trial. The study will assess the safety and efficacy of ZYN002 in DEE, including Lennox-Gastaut and Dravet syndromes. ZYN002 is the first and only pharmaceutically-produced cannabidiol (CBD) formulated as a patent-protected permeation-enhanced transdermal gel.

“DEE is a heterogeneous group of epilepsy syndromes that involve significant developmental impairment or regression of developmental progress, and are highly resistant to treatment,” said Dr. Liza Squires, Zynerba’s Chief Medical Officer. “Little attention is paid to DEE outside of Lennox-Gastaut and Dravet syndromes despite the high unmet need. The BELIEVE 1 study will assess children and adolescents with a variety of epilepsy syndromes that are characterized as DEE. Our goal is to deliver an effective, well tolerated, and easy to administer therapeutic option for individuals living with DEE and their families.”

The six-month BELIEVE 1 clinical trial is an open label multi-dose Phase 2 clinical trial designed to evaluate the efficacy and safety of ZYN002 in children and adolescents (three to <18 years) with DEE as classified by the International League Against Epilepsy (ILAE) (Scheffer et al. 2017). Approximately 50 patients with confirmed DEE will be enrolled in the clinical trial, approximately half of whom may have either Dravet or Lennox-Gastaut syndrome. Enrolled patients will receive weight-based initial doses of 125 mg BID (250 mg daily) or 250 mg BID (500 mg daily) of ZYN002 CBD gel. The primary efficacy assessment is change in seizure frequency. The Company expects to report topline results in 2019.

About Developmental and Epileptic Encephalopathies (DEE)
DEE is a heterogeneous group of epilepsy syndromes that may be associated with severe cognitive impairment and behavioral disturbances. These disorders are often progressive, and are highly resistant to treatment. DEE includes a number of rare and ultra-rare epilepsy syndromes including early myoclonic encephalopathy, epileptic encephalopathy with continuous spike and wave during sleep, and certain syndromes including Ohtahara, West, Landau-Kleffner, Lennox-Gastaut, Doose and Dravet. Improved seizure control may have a positive impact on development and quality of life.

About ZYN002
Zynerba’s ZYN002 CBD gel is the first and only pharmaceutically-produced CBD formulated as a patent-protected permeation-enhanced transdermal gel and is being studied in children and adolescents with Fragile X syndrome and developmental and epileptic encephalopathies, and in adult epilepsy patients with focal seizures. ZYN002 is a clear, permeation-enhanced gel that is designed to provide controlled drug delivery transdermally with once- or twice-daily dosing.
