About this trial

This is a two-stage trial consisting of a Part I, dose escalation and dose-finding component to establish the Maximal Tolerated Dose (MTD), if any, and Recommended Part 2 Dose (RP2D) of XON7, followed by a Part II component to investigate anti-tumors efficacy in selected solid tumor types and to further evaluate safety and tolerability of XON7 at RP2D.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Provide signed, written informed consent.

Male and female participant, age ≥ 18 years old (at the time consent is obtained)

Participant in phase I, must have a histologically or cytologically confirmed advanced or metastatic solid tumors for which no effective standard therapy is available. All tumor types except glioblastoma, could be included.

Participant in phase II, must have histologically or cytologically confirmed advanced or metastatic solid tumors of the following: NSCLC, gastro-esophageal adenocarcinoma, CRC, pancreatic cancer, Sarcoma, TNBC, or ovarian cancer.

Disqualifiers

A participant who has received more than 4 prior lines of therapy for advanced or metastatic disease.

A participant who has had a prior anti-cancer mAb within 3 weeks prior to trial Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier prior to trial Day 1.

A participant who has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to trial Day 1 or who have not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent (Except alopecia, hearing loss, grade 2 neuropathy or endocrinopathy managed with replacement therapy).

A participant with ≥Grade 3 toxicity related to prior immunotherapy leading to treatment discontinuation.
