Dose Escalating Study for Amphinex-based PCI of Bleomycin.
- Conditions
- Cutaneous or Sub-cutaneous Malignancies
- Interventions
- Registration Number
- NCT01872923
- Lead Sponsor
- PCI Biotech AS
- Brief Summary
The primary goal of this extension study is to further investigate the tolerability and efficacy in a phase I setting in order to see whether lower doses than the initial study dose of 0.25 mg/kg bw Amphinex in Amphinex-based PCI of bleomycin will show a comparable or improved safety and tolerability profile in combination with comparable signs of efficacy.
- Detailed Description
Use of Amphinex for the enhancement of Bleomycin at the intracellular target. The photosensitizer Amphinex is activated by Laser Light at 652 nm.
Superficial lesions (cutaneous or subcutaneous) was treated with the laser light after administration of Amphinex and Bleomycin according to time scheduled provided.
Safety and preliminary effect data where evaluated at a lower dose than explored in the preceeding dose escalating study with Amphinex.
Recruitment & Eligibility

- Have a performance status of 0-2 on the Eastern Cooperative Oncology Group (ECOG) Scale (see Appendix D)
- Clinically assessed as eligible for bleomycin chemotherapy
- Have a predicted life expectancy of at least 3 months
- Geographic proximity that allow adequate follow-up
- If female: have had childbearing potential either terminated by surgery, radiation, or menopause or attenuated by the use of an approved contraceptive method during and for 3 months after the trial
- If male: have had reproductive potential either terminated or attenuated by the use of an approved contraceptive method during and for 3 months after the trial.

- Primary Outcome Measures
Name Time Method To assess the combined tolerability and efficacy of Amphinex 0.125 mg/kg or lower in Amphinex-based PCI of bleomycin From Baseline to 3 months Maximal pain during the procedure will be recorded immediately after the procedure on a 10 centimetre visual analogue scale (VAS). Pain will also be recorded 24 hours after the illumination and on day 4. The end-points of the VAS will be "no pain" and "unbearable pain
A formal efficacy analysis is not appropriate for this trial. The response data will be documented by descriptive summary tables. No statistical comparison of dose levels will be done. Fluorescence measurements over time and lesion response evaluation according to RECIST (see Appendix E) will be presented for APT and PP stratified by dose level.
- Secondary Outcome Measures
Name Time Method To evaluate the safety of Amphinex 0.125 mg/kg or lower in Amphinex-based PCI of bleomycin. From Baseline to 3 months * Summaries of the adverse event rates and laboratory changes from baseline stratified by dose level.
* Listings and frequency tables categorizing laboratory and non-laboratory adverse events by maximum CTCAE toxicity grade and relationship to study drug.
* Pain measurement, fluorescence measurement, skin photosensitivity measurement
