About this trial

This is a first-in-human (FIH), Phase 1 open-label, multicentre dose escalation study investigating AVA6000 monotherapy administered intravenously in patients with locally advanced (unresectable) or metastatic solid tumours that are likely to be FAP positive. The study consists of an initial Phase 1a dose escalation portion and a subsequent Phase 1b dose expansion portion upon completion of the dose escalation portion.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

The patient has been fully informed about the study and has signed the Informed Consent Form.

Male or female patients, ≥ 18 years of age.

High grade soft tissue sarcoma: histologically proven locally advanced or metastatic, unresectable progressive or recurrent DDLS or UPS who have received 0 or 1 prior lines of therapy in the locally advanced or metastatic setting

SGC: Locally advanced or metastatic salivary gland confirmed by histopathology that cannot be completely resected by surgery who have received 0 or 2 prior lines of therapy in the locally advanced or metastatic setting. In addition, patients with adenoid cystic carcinoma subtypes must not have received prior cytotoxic therapy for locally advanced or metastatic disease. Adenoid cystic carcinoma subtype may be capped at 15 patients (assuming cohort of approximately 30 patients)

Disqualifiers

Has received trastuzumab within 7 months of the planned Cycle 1 Day 1 AVA6000 infusion.

Has received a prior total cumulative anthracycline dose of ≥ 350 mg/m2 doxorubicin (or equivalent anthracycline dose).

Has clinically significant or untreated central nervous system (CNS) metastases or leptomeningeal disease requiring treatment, as determined by the Investigator.

Patients who have any history of an active (requiring treatment) other malignancy (except any in-situ carcinoma, non-melanoma skin carcinoma and early prostate cancer with a normal PSA) within 2 years of study entry.
