Brief Summary

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.

Eligibility Criteria

Inclusion Criteria

1. Signed informed consent;

2. Male and female patients ≥ 18 years of age;

3. Malignancies resulting in cutaneous metastasis originating from: breast, lung, head and neck, pancreatic, urinary bladder, prostate, testicular, ovarian, uterine, cervical, gastric, adrenal, thyroid, parathyroid cancers, or other solid tumors;

4. Cutaneous metastases diagnosis confirmed prior to consent by preferred institutional methodology which may include, but is not limited to: biopsy; conventional radiography; imaging techniques to include bone scan (scintigraphy), computed tomography (CT), fluorodeoxyglucose-positron emission tomography (FDG-PET)/CT), magnetic resonance imaging (MRI), F-fluoromisonidazole-(F-FMISO) PET/CT, fluorothymidine-(FLT) PET/CT, fluoroestradiol-(FES) PET/CT, and PET/MRI;

5. ECOG Grade 0 - 2, with minimum life expectancy of at least 3 months;

6. At least one baseline eligible lesion. Per RECIST criteria (version 1.1), an eligible lesion at baseline is considered measurable when ≥ 10mm diameter in the longest diameter;

7. Willing to refrain from using lotions, creams, etc. during the treatment period;

8. Subjects with adequate organ and bone marrow function as defined below:

• ANC ≥ 1,500/µl
• Hemoglobin ≥ 9.5 grams/dL
• Platelets ≥ 75,000/µl
• AST (aspartate transaminase or SGOT)/ALT (alanine aminotransferase or SGPT) ≤ 3.0 x ULN and total bilirubin ≤ 2.0 x ULN with no evidence of cholestasis
• Creatinine ≤ 1.5x ULN;

9. Last dose of any systemic non-taxane cytotoxic chemotherapy completed at least one day prior to Day 1. Last dose of any systemic taxane cytotoxic chemotherapy completed at least 4 weeks prior to Day 1

10. Willing to use appropriate birth control for patients of child-bearing potential;

11. Abstinence from all manner of physical contact near the treatment area during and up to 2 weeks after the treatment phase.

Exclusion Criteria

1. Open or ulcerated wound(s) extending through the dermis within the treatment area;

2. Colorectal, hepatocellular, gallbladder, cholangiocarcinoma, neuroendocrine, melanomas, hematological and central nervous system (CNS) malignancies;

3. Active viral hepatitis A, B, or C or preexisting or acute liver disease;

4. Systemic treatment or localized treatment to target area with the following within the 4 weeks prior to the first treatment visit: radiotherapy, intralesional therapy; laser therapy surgery (other than biopsy), local hyperthermia, levulinic acid, 5-fluorouracil, high potency corticosteroids (including systemic steroids), retinoids, diclofenac, hyaluronic acid, imiquimod;

5. Elective surgery for treatment of the cutaneous metastases during the study and up to 4 weeks after the treatment period. Cutaneous metastases are required to remain in-situ and measurable for up to 2 weeks after last treatment to achieve study objectives;

6. Known allergic reactions, irritations or sensitivity to the active ingredients or other components of SOR007;

7. Symptoms of a clinically significant illness that may place the subject at risk by trial participation or influence the outcome of the trial in the four weeks before first treatment and during the trial;
