Brief Summary

This is a 2 part, multi-center, open-label, First-in-Human clinical study to evaluate the safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of INT-1B3 in the treatment of patients with advanced solid tumors.

Detailed Description

The investigational medicinal product INT-1B3 is a lipid nanoparticle formulated microRNA (miR-193a-3p) mimic destined for therapeutic intervention in oncology. Preclinical work showed that INT-1B3 has a multi-target mechanism of action with an anti-proliferative, anti-metastatic, anti-migration, cell cycle disruption, induction of apoptosis effect and modulation on the tumor microenvironment leading to significant induction of T cell-mediated immune response.

The first part of the study (Phase I) is a dose-escalation phase to determine the maximal tolerated dose and the recommended Phase 2 dose, as well as the safety profile of INT-1B3 in patients with advanced malignancies.The subsequent expansion phase of the study (Phase Ib) will further explore safety, pharmacokinetics, pharmacodynamic responses, and antitumor activity of INT-1B3 in patients with selected cancer types treated at the recommended phase 2 dose.

Exclusion Criteria

1. Patients on any other anti-cancer therapy, unless at least 4 weeks (or 5 half-lives, whichever is shorter), have elapsed since the last dose before the first administration of INT-1B3. At least 2 weeks should have elapsed since receiving non-palliative radiotherapy.

2. Patient with known central nervous system (CNS) metastases, unless previously treated and well-controlled for at least 1 month (defined as clinically stable, no edema, no steroids and stable in 2 scans at least 4 weeks apart)

3. Patient with concomitant second malignancies unless curatively treated at least 2 years before study entry with no additional therapy required or anticipated to be required during the study period

4. Patient with major surgery within 5 weeks before initiating treatment or with minor surgical procedure within 7 days before initiating treatment

5. Patient with active autoimmune disease or persistent immune-mediated toxicity caused by immune checkpoint inhibitor therapy of Grade ≥ 2, except for residual endocrinopathy adequately substituted, vitiligo, Type 1 diabetes mellitus or psoriasis not requiring systemic therapy (>10mg prednisone equivalent)

6. Patient with toxicity (except for alopecia) related to prior anti-cancer therapy and/or surgery, unless the toxicity is either resolved, returned to baseline or grade 1

7. Patient with any active neuropathy > Grade 2 (National Cancer Institute Common Terminology Criteria for Adverse Events v5.0)

8. Patient with any condition requiring concurrent use of systemic immunosuppressants or corticosteroids at a daily dose > 10 mg prednisone equivalent or other immunosuppressive medications within 14 days of study medication administration
