Study Description

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.

Condition or disease	Intervention/treatment	Phase
Solid Tumor	Drug: INT-1B3	Phase 1

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.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Phase 1/1b; Phase 1: dose escalation phase with a 'hybrid' 3+3 design in all-comers cancer patients. Approximately 30 patients will be included. Phase 1b: dose expansion phase in selected tumor types at the recommended phase 2 dose. Approximately 50 patients will be included.	Drug: INT-1B3; 60-min i.v. infusions twice per week in 21-day cycles

Outcome Measures

Primary Outcome Measures :

1. Incidence and severity of treatment-related adverse events and serious adverse events [ Time Frame: Up to 24 months ]

2. Recommended Phase 2 Dose of INT-1B3 [ Time Frame: Up to 24 months ]
   Based on dose-limiting toxicities, the maximal tolerated dose and all other available safety, pharmacokinetic/pharmacodynamic data as assessed by the cohort review committee

Secondary Outcome Measures :

   Area under the plasma concentration time curve of INT-1B3
2. Maximum plasma concentration [ Time Frame: Up to 24 months ]
   Highest observed plasma concentration of INT-1B3
3. Time of maximum plasma concentration [ Time Frame: Up to 24 months ]
   Time to reach highest observed plasma concentration of INT-1B3
4. Half-life [ Time Frame: Up to 24 months ]
   Plasma concentration half-life of INT-1B3
5. Objective response rate of INT-1B3 [ Time Frame: Up to 24 months ]
   Objective response rate according to standard criteria by RECIST1.1
