Actinic Keratosis (Cyclic PDT) | Clinical Trials

Study Description

Brief Summary

This is a pilot, phase 2, prospective, comparative study to evaluate the safety and efficacy of the combination of Levulan® Kerastick® for Topical Solution and blue light illumination using the BLU-U® Blue Light Photodynamic Therapy Illuminator (LevulanPDT).

The study hypothesis is that post solid organ transplantation patients, highly susceptible to non-melanoma skin cancer, can be treated safely and effectively through clinical cyclic application of PDT, lessening morbidity and possible mortality for this immunosuppressed patient population.

Outcome Measures

Primary Outcome Measures

Primary prevention of AKs in recently transplanted solid organ recipient [ Time Frame: 3 Years ]
Number of AK will be counted for each site using the photographs of the treatment and the control areas. AKs will be graded by thickness.
Time to occurrence of AKs in recently transplanted solid organ recipient [ Time Frame: 3 Years ]
Time to occurrence of AK will be calculated from the first visit to the development of an AK in the treatment areas and in the control areas.
Primary prevention of NMSC in recently transplanted solid organ recipient [ Time Frame: 3 Years ]
Number of NMSC will be counted for each site using the photographs of the treatment and the control areas. NMSC, including basal cell carcinoma, Bowen’s disease and squamous cell carcinoma, will be diagnosis and confirmed histologically by biopsy.
Time to occurrence of NMSC in recently transplanted solid organ recipient [ Time Frame: 3 Years ]
Time to occurrence of NMSC will be calculated from the first visit to the development of an NMSC in the treatment areas and in the control areas.

Secondary Outcome Measures

Pain control with Levulan-PDT in Solid Organ Transplant Recipient [ Time Frame: Day 1, Day 30, Day 180, 12 months, 18 months, 24 months, 30 months, 36 months ]
Pain will be assessed on the 10 point Visual Analogue Scale (VAS), as mild (0-3), moderate (4-7) or severe (8-10). Patients will be asked to rate the pain at the beginning, midway point (approximately 8 minutes later), and at the end of each PDT session.
The number of participants with treatment related adverse events as assessed by the CTCAE v4.0 [ Time Frame: 3 Years ]
The number of evaluable study participants who had a grade 3 or higher adverse event (AE) or any serious adverse event that’s determined to be at least possibly or probably related to study treatment, or any AE which is at least possibly or probably related to study treatment that causes permanent study discontinuation.

Eligibility Criteria

Ages Eligible for Study:	18 Years and older (Adult, Older Adult)
Sexes Eligible for Study:	All
Accepts Healthy Volunteers:	No

Inclusion Criteria

Received solid organ transplant
3-24 months post-transplant (any number of transplant)
Time interval of at least 6 days duration where complications such as rejection episodes, viral infections, surgical interventions and therapies with mono or polyclonal antibodies are ruled out by the transplant team.
No prior history of NMSC in the treatment fields
No AK/Bowen’s disease in the treatment fields within the last 3 months.
Moderate to severe sun damage
Be willing to forego other interventions in the treatment fields than the ones approved by the investigator that would interfere with the protocol or evaluation of the study medication

Exclusion Criteria

Patients with Fitzpatrick’s scale skin type IV-VI
Cutaneous photosensitivity to wavelengths of 400-450 nm, porphyria or known allergies to porphyrins
Known sensitivity to any of the components of the Levulan® Kerastick® for Topical Solution
Prior use of topical or systemic therapies that might interfere with the evaluation of the study medication during the study, within a 3 month washout period from the time of the screening visit
Unable to return for follow-up visits and tests
Any condition or situation which in the Investigator’s opinion may put the subject at significant risk, could confound the study results, or could interfere significantly with the subject’s participation in the study
