` 1 EXECUTIVE SUMMARY
`
`
`
`
`
`
`
`
`
`This review described the statistical findings of Kynmobi (apomorphine hydrochloride
`
`
`
`
`
`
`
`
`
`sublingual film) as an acute, intermittent treatment of “OFF” episodes associated with
`
`
`
`
`
`
`
`
`Parkinson’s disease. The review confirmed that Study CTH-300 - a randomized, double-blind,
`
`
`
`
`
`
`
`placebo-controlled, parallel-group study - in the 505(b)(2) new drug application provided
`
`
`
`
`
`
`
`
`
`
`
`statistical evidence that Kynmobi is efficacious: Kynmobi is statistically better than placebo in
`
`
`
`
`
`
`
`
`
`
`
`
`terms of the change from pre-dose to 30 minute post-dose in the Movement Disorders Society
`
`
`
`
`
`
`
`
`
`
`
`Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) Part III (Motor Examination) score at
`
`
`Week 12.

`
`
` 2.1 Overview
`
`
`
`
`
`
`
`
`
` On March 29, 2018, Sunovion Pharmaceuticals, Inc. (the Applicant) submitted a 505(b)(2) new
`
` drug application (NDA) for apomorphine hydrochloride sublingual film (APL-130277 under the
`
`
`
`
`
`
`
` Applicant’s clinical development program) as an acute, intermittent treatment of “OFF” episodes
`
`
`
`
`
`
`
`
` associated with Parkinson’s disease (PD). The NDA submission lists Food and Drug
`
`
`
`
`
`
`
` Administration approved drug Apokyn® (NDA 021264) as the 505(b)(2) reference. The
`
`
`
`
`
`
`Applicant submitted one clinical study in the NDA to support the efficacy claim of APL-130277.
`
`
`
`
`
`
`
`
`This clinical study is summarized below and reviewed in Section 3.

` 3 STATISTICAL EVALUATION
`
`
` 3.1 Data and Analysis Quality
`
`
`
`
`
`
`
`
`
`
`
`The data quality and analysis quality are adequate. The statistical reviewer was able to perform
`
`
`
`
`
`
`
`
`
`
`independent review using the Applicant’s submitted datasets and confirm the Applicant’s
`
`
`analysis results.

`
`3.2 Evaluation of Efficacy
`
`
`
`
`
`
`3.2.1 Study Design and Endpoints
`
`
`
`
`
`
`
`
`Study CTH-300 was a Phase 3, randomized, double-blind, placebo-controlled, parallel-group, 2
`
`
`
`
`
`
`
`
`arm, multi-center study to evaluate the efficacy, safety, and tolerability of APL-130277 in
`
`
`
`
`
`
`
`
`patients with PD. Approximately 126 patients were planned to be enrolled; approximately 114
`
`
`
`
`
`
`
`
`
`
`
`
`
`patients were planned to be randomized in a 1:1 ratio to placebo and APL-130277 groups.

`
`Figure 1 depicted the study design schematic of Study CTH-300. The study consisted of a dose
`
`
`
`
`
`
`
`
`
`
`titration phase and a 12-week double-blind maintenance treatment phase. In the dose titration
`
`
`
`
`
`
`
`phase, patients had up to six titration visits. The minimum titration dose was 10 mg APL
`
`
`
`
`
`
`
`
`130277; the maximum titration dose was 35 mg APL-130277.

`
`Figure 2 depicted the dosing paradigm of the dose titration phase. Before each titration visit or
`
`
`
`
`
`
`
`
`
`
`
`
`maintenance visit, patients were instructed to take their last dose of Levodopa (L-Dopa) and any
`
`
`
`
`
`
`
`
`
`other adjunctive PD medication no later than midnight on the evening prior and skip their regular
`
`
`
`
`
`
`
`
`
`
`morning does of L-Dopa or any other adjunctive PD medications on the day of the visit. During
`
`
`
`
`
`
`
`
`
`
`
`each titration visit, the patients was presented to the clinic in an “OFF” state then treated with
`
`
`
`
`
`
`
`
`
`
`
`
`
`APL-130277; the patient and investigator assessed whether the patient responded to the APL
`
`
`
`
`
`
`
`
`130277 with a full “ON” response within 45 minutes of taking APL-130277. Per the clinical
`
`
`
`
`
`
`
`
`
`
`
`
`
`study protocol, a patient-assessed full “ON” is defined as “a period of time where medication is
`
`
`
`
`
`
`
`
`
`
`providing benefit with regard to mobility, stiffness and slowness and where a patient feels he/she
`
`
`
`
`
`
`
`
`
`
`can perform normal daily activities; AND the response is comparable to or better than their
`
`
`
`
`
`
`
`
`
`
`normal response to PD medications prior to enrolling in the study”; an investigator-assessed full
`
`

`
`
`
`
`
`
`
`
`
`
`
`
`
`
` “ON is defined as “per clinical judgment, the period of time where the Investigator feels the
`
`
`
`
`
` medication is providing benefit with regard to mobility, stiffness and slowness and the patient
`
`
`
`
`
`
` has adequate motor function to allow them to perform their normal daily activities”. Patients who
`
`
`
`
`
`
`
`
`
` achieved a full “ON” response, as assessed by the patient and investigator, within 45 minutes of
`
`
`
`
`
`
`
`
`
` taking APL-130277 proceeded to randomization and the maintenance treatment phase at this
`
`
`
`
`
`
`
`
`
` dose, otherwise, patients were titrated to the next dose level in the next titration visit.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`Following the dose titration phase, patients were randomized in a 1:1 ratio to placebo and APL
`
`
`
`
`
`
`
`
`
`
`
`
`130277 groups and returned to the clinics at monthly interval during the 12-week double-blind
`
`
`
`
`
`
`
`maintenance treatment phase. Per the Schedule of Event Table in the protocol, the randomization
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`and Maintenance Visit 1 (MV1) were planned to occur on Day 23, Maintenance Visit 2 (MV2)
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`on Day 51, Maintenance Visit 3 (MV3) on Day 79, and Maintenance Visit 4 (MV4) on Day 100,
`
`
`
`
`
`
`
`
`
`
`with a window of ± 2 days. This indicates that the actual time length from randomization to MV4
`
`
`
`
`
`
`
`was around 11 weeks and less than 12 weeks.
`
`
`
`
`
`
`
`
`
`
`
`
`
`The primary efficacy endpoint was the change from pre-dose to 30 minutes post-dose in the
`
`
`
`
`
`
`
`MDS-UPDRS Part III score at Week 12 (i.e. MV4).
`
`
`
`
`
`
`
`
`
`
`
`
`
`The key secondary efficacy endpoint was the percentage of subjects with a patient-rated full “ON”
`
`
`
`
`
`
`
`response within 30 minutes at Week 12.
`
`
`
`3.2.2 Statistical Methodologies
`
`
`
`
`
`
`
`
`
`
`The efficacy analysis population was the modified intent-to-treat (mITT) population, defined as
`
`
`
`
`
`
`
`
`
`
`
`
`
`all subjects who were randomized, received at least one dose of study medication, and had at one
`
`
`post-randomization evaluation.
`
`
`
`
`
`
`
`
`
`
`
`The primary endpoint was analyzed using a mixed model with repeated measure (MMRM), with
`
`
`
`
`
`
`
`
`
`treatment, visit (MV1, MV2, MV3, and MV4), treatment by visit interaction as fixed effects and
`
`
`
`
`
`
`
`
`
`
`
`
`
`the change from pre-dose to 30 minutes post-dose in the MDR-UPDRS Part III score at the last
`
`
`
`
`
`
`
`
`titration visit as the covariate. The unstructured variance-covariance matrix was used for the
`analysis.
`
`
`
`
`
`
`
`
`
`
`The key secondary endpoint was analyzed using a generalized linear mixed model on binary data
`
`
`
`
`
`
`
`
`with logit link. The model included treatment, visit (MV1, MV2, MV3, and MV4), and treatment
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`by visit interaction as fixed effects and the “ON/OFF” assessment at the last titration visit as the
`
`
`
`
`
`
`covariate. The unstructured variance-covariance matrix was used for the analysis.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`The primary and key secondary endpoints were planned to be tested sequentially, each test at the
`
`two-sided significance level of 0.05.

`
`
` A total of 80 patients completed the study: 46 in the placebo group and 34 in the APL-130277

`
`
`
`
` Figure 3 illustrated observed means of the change from pre-dose to 30 minutes post-dose in the
`
`
` MDS-UPDRS Part III score by visit and treatment for the mITT population. The APL-130277
`
`
`
`
`
`
`
`
` group appeared to have consistent mean improvements of the MDS-UPDRS Part III score based
`
`
`
`
`
`
`
`
`
`
`
`
` on the observed mean changes from pre-dose to post-dose assessments. Such improvements were
`
`
`
`
`
`
`
`
`
`
` on average greater than those from the placebo group at each maintenance visit. However, the
`
`
`
`
`
`
`
`
`
`
`
`
` placebo effect also appeared to exist. The observed mean changes of pre-dose to post-dose
`
`
`
`
`
`
`
`
`
`
`
`
` appeared to decrease over time for both treatment groups, but the trends could be affected by
`
`
`
`
`
`
`
`
`
`
`
` high percentages of missing observations in both treatment groups. The percentages of missing
`
`
`
`
`
`
`
` observations at MV4 were 16.4% and 37.0% for the placebo group and APL-130277 group,
`
`
`
`
`
`
`
`
`
`
` respectively.

` Table 5 presented the analysis results of the change from pre-dose to 30 minutes post-dose in the
`

`

` MDS-UPDRS Part III score at Week 12. APL-130277 was statistically significantly better than
`
`
`
`
`
`
`
` placebo (p-value = 0.0002), with a least square APL-130277-placebo difference of -7.6 points
`
`
`
`
`
`
`
`
`
` (95% Confidence Interval (CI) = (-11.5, -3.7)). The Applicant performed several sensitivity
`
`
`
`
`
`
`
`
`
` analyses with missing data imputed under the missing at random assumption and the missing not
`
`
`
`
`
`
`
`
`
`
` at random assumption, respectively. The results from these sensitivity analyses supported the
`
`
`
`
`
`
`
`
`
`
`
`
` primary analysis results. For example, the Applicant used multiple imputation assuming that the
`
`
`
`
`
`
`
`
`
`
`
` trajectories of the patients after discontinuation follow those of the placebo group and obtained a
`
`
`
`
`
`
`
` nominal p-value = 0.0068. Applicant’s tipping point analysis assumed that trajectories of the
`
`
`
`
`
`
`
`
` patients in the APL-130277 group after discontinuation are worse by delta and showed that the
`
`
`
`
`
`
`
`
`
`
`
` statistical significance was lost when delta was greater than 8 points in MDS-UPDRS Part III
`
`
`
`
`
`
`
`
`
`
`
`
`
` score.

`
`

`
`
`
`
`
`

`
` 130277-placebo difference appeared to be consistent over time. The difference between the
`
`
`
`
`
`
`
`
`
` observed mean and least square mean for the APL-130277 group is the largest at MV4,
`
`
`
`
`
` compared to the differences of observed mean and least square mean for the APL-130277 group
`
`
`
`
`
`
` at other maintenance visits. This is likely caused by the high percentage of missing observations
`
`

`
`

`
`
`
`
`
` at MV4.

` 4 FINDINGS IN SPECIAL/SUBGROUP POPULATIONS
`
`
`
`
`4.1 Gender, Race, Age, and Geographic Region
`
` Overall, there is no compelling evidence from the subgroup analyses that a specific gender, race, or
`
`
`
`
`
`
`age subgroup benefits differently from APL-130277.

`
`Study CTH-300 was conducted mainly in the US. Only one patient the mITT population was
`
`
`
`
`
`
`
`
`
`
`
`from a Canadian study center. Therefore, subgroup analysis by geographic region (US vs. non-
`
`
`US) was not performed.
