- Participation in another experimental treatment protocol during the study period
- Major surgery in previous 3 weeks
- require or likely to require corticosteroids for intercurrent disease
- pregnancy at the entry or women who are breast feeding
- Patients without adequate protection against pregnancy during the conduct of the study and for three months after the last injection (intra-uterine device, hormonal contraception or diaphragm/condom and spermicide)

Primary Outcome Measures
NameTimeMethod
* Primary Endpoint Phase I Step (Cohorts 1 to 4):<br>The primary study endpoint was the MTD. <br>Dose limiting toxicity is defined as the level at which a Grade 4 toxicity, thought to be related to treatment, is observed, or the level at which more than 2 out of 6 patients experience Grade 3 toxicity thought to be related to treatment. <br>The MTD is defined as the dose level immediately below the dose with dose limiting toxicity. In the event the MTD was not reached in the three dosing cohorts planned, the MTD was defined as 3x1011 tp, the dose administered Cohorts 3 and 4. <br>Separate analyses were performed to tabulate the incidence of less severe events at each dose level. The frequency of development of humoral immunity at each dose was noted.<br><br>* Primary Endpoint Phase II Step (Cohort 5):<br>The Global response rate according to the investigator's assessment and based on evaluation of both injected and non-injected lesions.
Secondary Outcome Measures
NameTimeMethod
* Secondary Endpoints Phase I Step (Cohorts 1 to 4):<br>1. Evaluation of injected lesions: Antitumor response to the adenovirus IFNg. <br>2. Biological activity: Percentage of patients with positive response as measured by immunology testing. <br>3. Safety: Frequency of AEs overall and by cohort.<br>4. Time to treatment failure, duration of response, time to relapse requiring treatment and survival time.<br><br>* Secondary Endpoints Phase II Step (Cohort 5):<br>1. Local response rate based on evaluation of injected lesions.<br>2. Distant response rate based on evaluation of non-injected lesions.<br>3. Frequency of AEs overall and by cohorts.<br>4. Time to treatment failure, duration of response, time to relapse requiring treatment,survival time.
