Brief Summary:
Phase 1 is an open-label, multi-center dose escalation/dose expansion study designed to assess the safety, tolerability and pharmacokinetics (PK) for the recommended phase 2 dose (RP2D) of IMX-110. The RP2D will be evaluated in a further dose expansion Phase 2a study submitted.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 70 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1/2a Open-Label, Dose-Escalation/Dose-Expansion Safety, Tolerability and Pharmacokinetic Study of IMX-110 in Patients With Advanced Solid Tumors
Actual Study Start Date : February 15, 2018
Estimated Primary Completion Date : July 15, 2020
Estimated Study Completion Date : July 15, 2021


Arm Intervention/treatment
Experimental: Imx-110 Drug: Imx-110
a nanoparticle encapsulating a Stat3/NF-kB/poly-tyrosine kinase inhibitor and low-dose doxorubicin




Primary Outcome Measures :
  1. Number of participants with treatment-related adverse events assessed by CTCAE v4.03. [ Time Frame: 28 days ]
  2. Maximum tolerated dose (MTD) of IMX-110 in patients with advanced solid tumors for evaluation in Phase 2a. [ Time Frame: 28 days ]
    The MTD is defined as the highest dose at which ≤ 33% of the patients treated during the 3+3 design experience a DLT and/or at least two ≥ grade 2 toxicities during the first treatment cycle, and will be used to identify the RP2D to be taken forward to Phase 2a.

  3. Recommended Phase 2 Dose (RP2D) of IMX-110 in patients with advanced solid tumors [ Time Frame: 28 days ]
    RP2D is defined as one dose level below MTD


Secondary Outcome Measures :
  1. Plasma concentrations of IMX-110 [ Time Frame: 5 days ]
    Plasma concentrations of IMX-110 will be measured when administered in treatment Cycle 1. Samples will be collected on the first day (pre-dose, 0.5, 1, 2, 4, 6 and 24 hours post-dose) and the 5th day of dosing (pre-dose, 0.5, 1, 2, 4 and 6 hours post-dose).

  2. Response Rate [ Time Frame: 8 weeks ]
    Objective Response Rate as determined by Response Evaluation Criteria in Solid Tumors (RECIST) criteria version 1.1.

  3. Progression-free survival (PFS) [ Time Frame: 5 years ]
    PFS is measured from the start of treatment to the time of progression or death, whichever occurs first while on the study.

  4. Overall Survival (OS) [ Time Frame: 5 years ]
    OS is defined as the time from Cycle 1 Day1 to death due to any cause.

  5. Duration of Response (DOR) [ Time Frame: 5 years ]
    DOR as determined by RECIST criteria version 1.1.


Other Outcome Measures:
  1. Pharmacodynamic activity of IMX-110 with appropriate biomarkers. [ Time Frame: Baseline and the end of Cycle 1 (each cycle is 28 days) ]

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Male or female patients who are 18 years or older
  2. Patients with confirmed advanced solid tumor as per histology, who have progressed, are refractory, or are intolerant to standard therapy appropriate for tumor type
  3. Patients with an Eastern Cooperative Oncology Group (ECOG) Performance status of 0-2 (Appendix 2)
  4. Patients with a life expectancy of at least 3 months
  5. Patients with adequate cardiac function as measured by left ventricular ejection fraction >50%
  6. Patients who meet the following laboratory requirements:

    1. Absolute neutrophil count (ANC) ≥ 1.0 x 10^9/L
    2. Hemoglobin (HGB) ≥ 90.0 g/L (patients may be transfused to achieve this HGB level)
    3. Platelet count ≥ 100 x 10^9/L
    4. Total bilirubin level ≤ 1.5 x ULN
    5. AST and ALT ≤ 2.5 x ULN (≤5 x ULN if liver metastasis present)
    6. Creatinine ≤ 1.5 x ULN (Creatinine clearance >50 mL/min/1.73 m2 for subjects with creatinine levels above institutional normal)
  7. Women of childbearing potential and men must agree to use highly effective, double barrier contraception during the study and for 6 weeks following the final dose of IMX-110. Double barrier contraception is defined as a condom AND one other form of the following:

    1. Birth control pills (The Pill)
    2. Depot or injectable birth control
    3. IUD (Intrauterine Device)
    4. Birth control patch (e.g. Ortho Evra)
    5. NuvaRing®
    6. Documented evidence of surgical sterilization at least 6 months prior to the screening visit, i.e., tubal ligation or hysterectomy for women or vasectomy for men.

Male patients must not donate sperm for at least 24 weeks post-dose of the last study treatment. Male partners of female patients and female partners of male patients must also use contraception, if they are of childbearing potential.

Females of childbearing potential must have a negative serum pregnancy test at Screening and a negative urine pregnancy test on Day -1.

  1. Patients with a history of severe allergic reactions to any unknown allergens or any components of the study drug formulation.
  2. Patients receiving any chemotherapy within 14 days of dosing, immunotherapy within 28 days of dosing, or biologic or hormonal therapy within 28 days of dosing for cancer treatment. Patients with prostate cancer can continue administration of Gonadotropin-releasing hormone (GnRH) agonists.
  3. Subject participating in any other drug study ≤ 4 weeks (6 weeks for immunotherapy investigational agents) or 5 half-lives of the investigational product, whichever is longer, prior to study drug administration or is scheduled to receive one during the treatment or post-treatment period.
