Safety and Efficacy of Intramuscular Electrotransfer of Plasmid AMEP in Patients Suffering From Advanced or Metastatic Melanoma
- Conditions
- Melanoma
- Interventions
- Biological: naked DNA coding for protein AMEP
- Registration Number
- NCT01764009
- Lead Sponsor
- Valerio Therapeutics
- Brief Summary
The objective of the present trial is:
* to determine the dose limiting toxicity (DLT), maximal tolerated dose (MTD) and recommended phase 2 dose (RP2D) of intramuscular electrotransferred Plasmid AMEP in patients with advanced or metastatic melanoma.
* to determine the local and general safety of intramuscular electrotransferred Plasmid AMEP
* to evaluate the efficacy of intramuscular electrotransferred Plasmid AMEP
- Detailed Description
In this open-label, multicentre, dose escalation phase I study, successive cohorts of 3 patients suffering from advanced or metastatic melanoma will be electrotransferred increasing doses of Plasmid AMEP into muscle. Treatment will be repeated every 28 days until progression or limiting toxicity.
Consecutive cohorts of 3 to 6 patients will be treated with increasing doses of Plasmid AMEP at three dose levels: 0.25 mg, 1 mg and 4 mg according to an adapted 3+3 design. There will be no intra-patient dose escalation.

- Primary Outcome Measures
Name Time Method Safety-Dose Limiting toxicity determination 8 weeks Dose Limiting Toxicity (DLT) defined as any grade 4 clinical or biological event related to the study treatment and occurring during the first and second course (8 weeks) Safety parameters will be assessed according to the NCI-CTCAE v4.0 classification
- Secondary Outcome Measures
Name Time Method Safety- determination of the repeated dose 8 weeks Main secondary endpoints will be safety parameters; the evaluation of efficacy parameters will allow identifying preliminary efficacy of Plasmid AMEP alone and determining the RP2D.
