Study of Topical SOR007 Ointment for Cutaneous Metastases

November 3, 2021 updated by: NanOlogy, LLC

Phase 1/2 Dose-Rising, Safety, Tolerability and Efficacy Study of Topical SOR007 for Cutaneous Metastases

This study evaluates a topical nanoparticle paclitaxel ointment (SOR007) for the treatment of cutaneous metastases from non-melanoma cancer in adults. Three concentrations of SOR007 will be evaluated in dose-rising cohorts of three. An expanded cohort will treat additional subjects at the maximum tolerated dose.

Detailed Description

This is a Phase 1/2, open-label, dose-rising study evaluating the safety, tolerability and preliminary efficacy of three concentrations of SOR007 (Uncoated Nanoparticle Paclitaxel) Ointment (0.15%, 1.0%, and 2.0%) applied to non-melanoma cutaneous metastases. A treatment area of 50 cm2 will be selected by the Investigator. Using a gloved hand, subjects will apply one Finger Tip Unit (FTU) of SOR007 to the 50 cm2 treatment area twice daily at approximately the same time each day for 28 days, with the option of extending treatment an additional 28 days to total 56 days for subjects in the dose expansion phase. At each visit (Days 1, 8, 15, 29, and 43 for 28 treatment days; Days 8, 15, 29, 57, and 70 for 56 treatment days), at least two global and two close-up color photographs of the treatment area will be taken (with a ruler for scale). The photographs will be analyzed with ImageJ. Eligible lesions will be determined at baseline by the RECIST definition of measurable tumors (≥ 10mm in its longest diameter). The study will include a dose escalation phase and a dose expansion phase.

In the dose escalation phase, formal safety reviews will be conducted after the last subject in each cohort of three subjects completes 15 days of treatment. The next dose level will enroll upon a finding of safety and tolerability. The top dose or the maximum tolerated dose (if DLT occurs) will be taken into the dose expansion phase and additional subjects will be enrolled to reach a maximum of 16 subjects at that dose.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of Treatment Emergent Adverse Events
Time Frame: Baseline through Day 59 (for 28 days of treatment) or Day 86 (for 56 days of treatment)
Treatment emergent adverse events will include all reported adverse events, laboratory assessments, physical examination findings, and vital signs.
Baseline through Day 59 (for 28 days of treatment) or Day 86 (for 56 days of treatment)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Objective Clinical Response
Time Frame: Baseline and Day 43 (for 28 days of treatment) or Day 70 (for 56 days of treatment)

Objective Clinical Response (Complete Clinical Response (CR) + Partial Response (PR)) is defined as the percentage of study subjects who achieve complete clinical response or partial response 14 days after last treatment (Day 43 or Day 70).

Complete clinical response (CR) is defined as absence of any detectable residual disease in the treatment area; partial response (PR) as at least a 30% decrease in the sum of the diameters of eligible lesion(s) within the treatment area compared to baseline; progressive disease (PD) as at least a 20% increase in the sum of diameters of eligible lesion(s) within the treatment area, taking as reference the smallest sum on study (the sum must also demonstrate an absolute increase of at least 5 mm); and stable disease (SD) as between that defined as PR or PD. Eligible lesions will be determined at baseline by the RECIST definition of measurable tumors (≥ 10mm in its longest diameter).

Baseline and Day 43 (for 28 days of treatment) or Day 70 (for 56 days of treatment)
Change in Pain at the Treatment Area
Time Frame: Baseline and Day 43 (for 28 days of treatment) or Day 70 (for 56 days of treatment)
Change in pain at the treatment area will be measured by the Numeric Rating Scale (NRS-11). The numerical scale ranges from 0 to 10, with 0 being "no pain" and 10 being "the worst pain imaginable." A lower score equates to less severe pain (better outcome) and a higher score equates to more severe pain (worse outcome).
Baseline and Day 43 (for 28 days of treatment) or Day 70 (for 56 days of treatment)
Objective Tumor Response (OTR)
Time Frame: Baseline and Day 43 (for 28 days of treatment) or Day 70 (for 56 days of treatment)
Objective Tumor Response (OTR), defined as the difference in the lesion size within the treatment area between baseline and 14 days after the last dose in the dose group i.e. Day 43 for dose escalation Subjects, and dose expansion Group A Subjects; Day 70 for dose expansion Group B Subjects; or between baseline and last tumor assessment for early terminators. Four OTRs are calculated based on different definitions of "lesion size": 1) Area of the primary eligible lesion, 2) Sum of area of all eligible lesions, 3) Longest diameter of the primary eligible lesion, and 4) Sum of longest diameter of all eligible lesions.
Baseline and Day 43 (for 28 days of treatment) or Day 70 (for 56 days of treatment)
