Description détaillée
Study Design:
In this open-label, dose escalation study, subjects will receive a single IV loading dose of SYN004 on Day 1 of the first treatment week, followed by up to 7 fixed weekly doses of SYN004. Subjects will be assigned to loading and fixed doses by dose group.
Each dose group will comprise 3 subjects and may be expanded to 6 subjects. Subjects will enter dose groups in the order in which they are enrolled. There will be no intra-subject dose adjustments.
Only 1 subject in a cohort may receive the loading dose of SYN004 on any given day; at least 1 day must elapse before the next subject in the cohort receives the loading dose.
Study SYN004-001 Dose Matrix. Three initial subjects will be enrolled followed by an additional three if specified by protocol. Dose levels are specified below.
Group 1: Loading dose: 100 mg/m2; Weekly Dose: 62.5 mg/m2. Group 2: Loading dose: 200 mg/m2; Weekly Dose: 125 mg/m2. Group 3: Loading dose: 400 mg/m2; Weekly Dose: 250 mg/m2.
After each dose of IV SYN004, subjects will be observed in the clinic for 12 hours. After the loading dose, subjects will undergo safety evaluations on Days 2, 3 and 5. Safety evaluation will also be performed on Day 1 (pre-treatment) and Day 3 of each fixed dose treatment week.
Dose-limiting toxicities (DLTs) are defined as any Grade ≥3 AE assessed by the investigator or Medical Monitor, with agreement of the Safety Review Board (SRB), as related to SYN004. Subjects with DLTs will be withdrawn from treatment. If 2 or more subjects in a dose group experience DLTs, or one subject in a dose group experiences a Grade ≥3 infusion reaction, all subjects in that dose group will be withdrawn from treatment.
Subjects in the dose groups are considered evaluable for dose escalation decisions if they receive at least 4 doses of SYN004, or discontinue SYN004 because of a DLT.
Subjects who withdraw or are terminated per protocol before receiving 4 doses of SYN004 will be replaced.
For subjects who receive at least 4 doses of SYN004, End of Study CT scans for RECIST (version 1.1) evaluation will be performed six (6) days following the final SYN004 treatment.
There will be a 28-day safety monitoring period following the final dose of SYN004 for all subjects in the study. All subjects will attend an End-of-Study Visit 28 days after the final dose of SYN004.
Subjects who complete Cycles 1 and 2, who have evidence of improvement per RECIST 1.1 (i.e., findings of complete or partial response per RECIST 1.1) and meet the other eligibility criteria will be offered up to 3 additional treatment cycles (i.e., up to 12 additional weekly doses) of SYN004 in the SYN004-001 Extension Study. During the Extension Study, subjects will receive the same fixed dose of SYN004 they received in Cycles 1 and 2.
Dose escalation will proceed according to a standard 3+3 study design.

- Ability to communicate with the investigator, and understand and comply with the requirements of the protocol;
- Agrees to notify the investigator when deviating from the protocol requirements with regard to concomitant medications;
- Agrees to stay in contact with the study site for the duration of the study and to provide updated contact information as necessary, and has no current plans to move from the study area for the duration of the study.
Exclusion Criteria:
- Participation in a study of an investigational agent or use of an investigational device at the time of screening or within 4 weeks of enrollment;
