SOR007 Ointment 0.15% applied to the face twice daily for 28 days

SOR007 Ointment 0.3% applied to the face twice daily for 28 days

SOR007 Ointment 1.0% applied to the face twice daily for 28 days

SOR007 Ointment 2.0% applied to the face twice daily for 28 days

SOR007 Ointment vehicle applied to the face twice daily for 28 days

SOR007 will be applied topically to a target AK lesion test field twice daily for up to 28 days, or until all lesions resolve. The maximum total amount of SOR007 that will be applied daily will be 1 finger-tip unit (FTU), approximately 0.5g. No more than 25cm2, approximately 0.15% of the total body surface area, will be treated.

SOR007 (Uncoated Nanoparticulate Paclitaxel) Ointment

SOR007 ointment vehicle will be applied topically to a target AK lesion test field twice daily for up to 28 days, or until all lesions resolve. The maximum total amount of Ointment vehicle that will be applied daily will be 1 finger-tip unit (FTU), approximately 0.5g. No more than 25cm2, approximately 0.15% of the total body surface area, will be treated.

A Phase 2, randomized, double-blind, dose rising study to determine the safety, tolerability, and preliminary efficacy of four concentrations of SOR007 (Uncoated Nanoparticulate Paclitaxel) Ointment (SOR007) compared to SOR007 ointment vehicle applied to actinic keratosis (AK) lesions on the face twice daily for up to 28 days.

In this Phase 2, randomized, double-blind, dose rising trial, subjects with actinic keratosis will receive topical application of SOR007 Ointment (in four concentrations) or SOR007 Ointment vehicle to the face twice daily for up to 28 days. Subjects will be enrolled in four dose-escalating cohorts of eight subjects and randomized to SOR0007 or Ointment vehicle in a ratio of 3:1. Cohorts will be enrolled sequentially starting at the lowest concentration.

Safety will be assessed in an ongoing manner and formal safety reviews will be conducted four times for each cohort: at Day 8, Day 15, Day 21, and Day 28 for the last subject enrolled in each cohort. The next dose level cohort will enroll upon a finding of safety and tolerability at the previous cohort's second (Day 15) safety review.

The safety and tolerability of SOR007 will be demonstrated by local toxicity, adverse events, laboratory assessments and vital signs. Subjects will be observed for reduction in the number of AK lesions to determine preliminary efficacy. Plasma samples will be taken at various time points throughout the study to characterize the pharmacokinetics of SOR007.

Phase 2, randomized, dose-rising, double-blind trial. Subjects will enroll in four dose-escalating cohorts of eight subjects each. Each cohort will be randomized to SOR007 or Ointment vehicle in a ratio of 3:1. Safety will be assessed in an ongoing manner and formal safety reviews will be conducted four times for each cohort: at Day 8, Day 15, Day 21, and Day 28 for the last subject enrolled in each cohort. The next dose level cohort will enroll upon a finding of safety and tolerability at the previous cohort's second safety review. Once the last cohort has completed the study, all available data, including safety, pharmacokinetics, and preliminary efficacy will be analyzed. The PK blood samples will be analyzed per cohort when the last subject of each cohort completes Day 28.

Study of SOR007 Ointment for Actinic Keratosis

Phase 2 Dose-Rising Study of SOR007 Ointment for Actinic Keratosis

Treatment emergent adverse events including all reported adverse events, laboratory assessments, physical examination findings, and vital signs.

Pharmacokinetic (PK) samples were taken on Day 1 at 1h, 2h, 4h, and 6h post application; on Day 8, Day 15, and Day 21 after the first daily application; and on Day 28 at 1h, 2h, 4h, 6h, and 12h after the first daily application.

AK lesions in the target test field were photographed and tracings were created at baseline and at subsequent visits to track whether lesions were clear or still present.

Percent change in size of AK lesions was determined with measurements obtained at Baseline and 56 days. A measurement was also obtained at Day 28, but was not used to calculated percent change for the purposes of this outcome measure.

Number of Participants With Treatment Emergent Adverse Events

Pharmacokinetics: Area Under the Plasma Concentration Versus Time Curve (AUC) of SOR007

Pharmacokinetics: Peak Plasma Concentration (Cmax) of SOR007

Pharmacokinetics: Time at Which Peak Plasma Concentration is Observed (Tmax) of SOR007

Two subjects, both receiving Vehicle, were withdrawn early from the study; one of these subjects participated long enough to be included in the analysis of the efficacy endpoint and one did not. Therefore, there are 8 subjects in the Ointment Vehicle arm of the study.
