Exhibit 99.1

Unreliable Absorption With Rectal Administration of Diazepam

ABSTRACT

Rationale: Until recently, diazepam rectal gel (DRG) has been the only FDA-approved treatment for the management of selected patients with epilepsy who experience bouts of increased seizure activity. However, the route of administration for DRG is not ideal, as it may be associated with embarrassment and the need for a private setting during administration. Diazepam buccal film (DBF) is a novel formulation of diazepam under development as a therapeutic alternative to DRG. A previously reported study comparing the bioavailability of DBF and DRG in healthy adults showed high variability in pharmacokinetic parameters following administration of DRG but not DBF, with some subjects showing on multiple occasions consistently low plasma concentrations following single doses of DRG. We assessed the available published literature to identify other reported instances of low systemic exposure following rectal administration of diazepam in individual subjects.

Methods: A search of the PubMed database was conducted to identify primary studies of rectal absorption of diazepam using the following search terms: “diazepam,” “absorption,” and “rectal.” Subjects were categorized as having low rectal absorption if they had diazepam plasma levels that were either: ≥1.5 standard deviations below the group mean; ≥2 standard errors below the group mean; <20% of the group median; ≤50 ng/mL and were group outliers; or explicitly reported as low plasma levels by study investigators. Findings from these studies were compared with observed data from the previously reported study of bioavailability following administration of DBF 15 mg versus DRG 5 mg, 12.5 mg, and 20 mg.


Results: The literature search identified 10 relevant studies reporting plasma levels following rectal administration of diazepam, comprising data from 159 subjects. In 4 of these studies (including the three smallest studies, N=6), no instances of low absorption were reported. In the remaining 6 studies, the proportions of subjects with low absorption of rectal diazepam ranged from 4.2% to 18.2% (Table). In the DBF versus DRG bioavailability study, 2 of 36 subjects (5.6%) consistently exhibited extremely low exposure (Cmax and AUC0-t greater than 2 standard deviations below the mean) following ≥2 DRG administrations separated by time; both subjects showed systemic exposure at or near the group mean following administration of DBF.

Conclusions: A majority of the studies identified by literature review reported subjects with low rectal absorption of diazepam; up to 18.2% of subjects showed low rectal absorption. In addition, observations from a recent comparative bioavailability study of DBF and DRG suggests that some patients may be predisposed to be non-absorbers of rectally administered diazepam.

Simulation of the Pharmacokinetics of Diazepam Buccal Film in Adult Patients with Epilepsy with Weight-adjusted Dosing

Allen H Heller, Gary Slatko, Michael A Rogawski

Rationale: Diazepam buccal soluble film (DBF) is a novel dosage form of diazepam under development for the treatment of acute repetitive seizures (ARS). In a study reported earlier (Rogawski et al., AES Abst. 2.453, 2018), we demonstrated that pharmacokinetic (PK) performance of DBF following a single 12.5 mg dose was similar under periictal and interictal conditions. The legacy product diazepam rectal gel (Diastat) is dosed acording to a weight-based dosing scheme. This study was undertaken to compare diazepam exposures obtained with DBF when dosing according to a weight-based regimen and as a fixed dose.

Methods: Adult men and women ages 17-65 years with poorly controlled tonic clonic seizures or focal seizures with impaired awareness (N=35) were enrolled. PK profiles valid for analysis for both treatment conditions were available for 21 subjects. Most of these subjects had samples collected up to 4 hours but 3 subjects were sampled only up to 2 hours. PK profiles were simulated based on body weight and robust evidence of dose-proportionality of the DBF product from healthy volunteer studies and population PK modeling.

Results: The table shows predicted values for Cmax, AUC(0-2h), and AUC(0-4h) (geometric means) and the ratio of the geometric means (Treatment B/Treatment A) with 90% confidence intervals. On average, predicted PK parameters were 17-18% higher compared with the 12.5-mg fixed-dose regimen, with median Cmax 263 ng/mL (interquartile range [IQR] 197-301 ng/mL) and 247 ng/mL (IQR 152-329 ng/mL) for the interictal and ictal/periictal conditions, respectively. Weight-based dosing provided a modest reduction in inter-subject variability. As expected, predicted values for Cmax, AUC(0-2h), and AUC(0-4h) were similar in interictal and ictal/periictal state. The figure shows the mean of the simulated plasma concentrations over time.

Conclusions: The simulated weight-based dosing regimen for administration of DBF to adults with epilepsy was associated with a higher predicted exposure than that observed with a fixed dose of 12.5 mg. These results suggest that the weight-based dosing regimen applied here (average dose 14.9 mg/kg) is associated with therapeutic diazepam plasma concentrations under both interictal and ictal/periictal conditions.

AES ABSTRACT

Patient and caregiver preference for route of administration of a benzodiazepine for control of increased seizure activity in stable patients

Rationale:  Patients with epilepsy on stable treatment regimens requiring intermittent use of a benzodiazepine as a rescue medication to control bouts of increased seizure activity may soon have access to diazepam or other benzodiazepines delivered through new routes of administration, such oral dissolving film or nasal spray.  However, little is known regarding caregiver and patient preference for routes of administration other than the currently approved diazepam rescue medication that is administered as a rectal gel.

Methods:  29 seizure patients and caregivers prescribed intermittent use of diazepam to control bouts of increased seizure activity participated in an online survey.  All participants completed a prescreen to insure they met the qualifications.   Respondents were asked to identify a preference for route of administration, initially without administration instructions, and then again after reviewing instructions for administration of each product.

Results: These results represent an interim analysis of 29 respondents engaged in an on-going 60 patient survey.  Of the 29 responders (15 patients and 14 caregivers) surveyed, all respondents reported 5 or more breakthrough seizures in the past 12 months and 55% had used diazepam to control episodes of seizure activity.  The majority of patients (80%) and caregivers (71%) initially preferred an oral dissolving film formulation to a nasal spray formulation.  Following a review of instructions for administration of each medication, 87% of patients and 86% of caregivers indicated a preference for oral dissolving film over nasal spray.

When selecting a rescue seizure medication, the most important factors identified by caregivers were effectiveness (93%) followed by immediacy of effect (71%) and ease of use (71%). Patients identified tolerability (60%), effectiveness (47%) and immediacy of effect (47%) as most important.

Overall, effectiveness (41%) and immediacy of effect (31%) were cited as the two most important considerations when choosing a route of delivery.  The amount of time to access, prepare, and administer the medication should ideally be either less than one minute (52% of respondents) or 2-5 minutes (41% of respondents).

Conclusion:   Most patients and caregivers chose an oral dissolving film over a nasal spray as their preferred route of administration for a benzodiazepine to control bouts of increased seizure activity based on perceived effectiveness, tolerability, and immediacy, and this preference became even more pronounced after they became more familiar with product administration.

Rationale: Diazepam buccal film (DBF) is a novel dosage form of diazepam under development for the management of patients with refractory epilepsy requiring intermittent use of diazepam to control increased seizure activity. We assessed the pharmacokinetic (PK) performance of DBF administered to adults with epilepsy according to a weight-based regimen (dose range 12.5–17.5 mg) compared to diazepam rectal gel (DRG) administered according to the weight-based regimen recommended in the FDA-approved label (dose range 12.5–20 mg).


Methods: Adult men and women ages 18–65 years with epilepsy on a stable regimen of ≥1 antiseizure drug (no change in the 30 days prior to receiving study drug and no change anticipated over the course of the study) were enrolled in a 2-period crossover study (NCT03953820) to receive a single dose of either DBF or DRG in randomized sequence and separated by a 28-day washout. Doses were administered within 30 min of a standardized moderate-fat meal. Subjects were confined to the clinic until 24 h after dosing. Diazepam plasma samples were obtained pre-dose and at intervals until 10 d after dosing to enable analysis of maximal plasma concentration (Cmax), time to Cmax (Tmax), area under the curve to the last measurable concentration (AUC0-T), and AUC extrapolated to infinity (AUC0-INF). Subjects were monitored for adverse events (AE) throughout the study.

Results: Among 31 subjects enrolled, PK profiles valid for analysis for both DBF and DRG were available for 28 subjects (13 males, 15 females; mean [SD] weight 84.6±20.6 kg). Subjects were excluded from analysis if both treatments were not completed (n=2), or if predose diazepam concentrations were >5% of Cmax (n=1). Diazepam mean (SD) dose was 15.4±1.9 mg and 17.1±3.0 mg for DBF and DRG, respectively. The table shows geometric means for PK parameters with ratio of geometric means (DBF/DRG) for the study population overall (N=28), and geometric means for Cmax and corresponding ratios within each weight category. For the study population overall, geometric mean Cmax values for DBF and DRG were 204.26 ng/mL (geometric SD [GSD] 136.12–306.49) and 211.22 ng/mL (GSD 87.71–508.63), respectively (see figure), indicating that Cmax values following DBF were comparable but significantly less variable than Cmax values following DRG (P<0.0001). Values for AUC were higher for DBF than for DRG, and median Tmax values for DBF and DRG were 1.0 and 0.52 h, respectively (P<0.05).Three of 28 subjects following DRG dosing failed to achieve a plasma concentration ≥70 ng/mL. There were no serious AEs related to study drug.

Conclusions: These results demonstrate that a single dose of DBF administered to adults with epilepsy following a moderate-fat meal according to a weight-based regimen provides exposure to diazepam similar to DRG dosed as recommended with significantly less variability. The geometric mean values for Cmax following DBF were consistently ≥150 ng/mL for each of the weight categories.

ABSTRACT

Rationale: Seizure clusters occur in many patients with epilepsy, despite treatment with antiepilepsy medications. Available treatment options remain limited. Diazepam buccal film (DBF) is a novel formulation of diazepam in development for these patients; it is designed to be easily administered, with a pharmacokinetic profile comparable to rectal diazepam. The primary objective of this ongoing study (NCT03428360) is to assess the safety and tolerability of self- or caregiver-administered DBF in people with epilepsy. Interim data from patients receiving ≥1 dose of DBF as of May 2019 are reported.

Methods: Patients 2 to 65 years old with a clinical need for rescue benzodiazepine at least once monthly were included in the study. DBF was dispensed at doses ranging from 5 to 17.5 mg based on age and body weight, and then administered by patients or caregivers in their home environment as clinically needed. DBF could be administered for up to 5 seizure episodes monthly. Outcomes of interest, including adverse events (AEs) and DBF usability assessed by patients/caregivers, were collected after the first dose and then every 3 months thereafter.


Results: A total of 72 patients were enrolled to date and have used DBF at least once (adults, n=59; adolescents, n=7; pediatric, n=6). Overall occurrences of AEs, as well as AE severity and relationship to study drug, are summarized in Table 1. Five (6.9%) patients reported a total of 7 treatment-related AEs over a mean (SD) of 192 (97) days of follow-up, and all were mild in severity. Local buccal discomfort (mild in severity) was reported in 1 patient, and there were no reports of injury during buccal placement of DBF. No patient discontinued study participation due to an AE. Thirteen serious AEs were reported, none of which were considered treatment-related. DBF usability data were reported by 64 of the 72 (88.9%) patients, representing a total of 471 DBF use occasions with a mean (SD) of 7.4 (7.7) administrations per patient. DBF was successfully administered during a first attempt on 443 of 471 (94.1%) use occasions and during a second attempt on another 17 (3.6%) use occasions. However, all 64 patients had first-attempt success at DBF administration on at least one use occasion. Reasons for unsuccessful placement among patients with ≥1 unsuccessful attempt are summarized in Table 2. Patients and caregivers reported no difficulty opening either the outer or inner packaging in the majority of use occasions and almost all reported no difficulty removing DBF from the inner packaging.

Conclusions: In this observational study of chronic, intermittent administration and use, DBF was found to be safe and well tolerated by pediatric, adolescent, and adult patients with epilepsy experiencing seizure emergencies. DBF was ultimately successfully placed on 99.6% (469/471) of use occasions and readily used without difficulty when administered by patients and caregivers.
