A Trial of HTI-1090 in Subjects With Advanced Solid Tumors

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03208959
Recruitment Status : Completed
First Posted : July 6, 2017
Last Update Posted : September 30, 2019

Atridia Pty Ltd.

Brief Summary:
IDO1 is expressed in a wide variety of human tumors (eg. bladder, breast, colon, DLBCL, HNSCC, lung, ovarian, uterine, renal…), and contributes to tumoral resistance. HTI-1090 (also referred as SHR9146 in nonclinical study reports) is an orally bioavailable, highly potent, novel small-molecule IDO1/TDO dual inhibitor, with favorable preclinical oral bioavailability and safety profiles.

Condition or disease Intervention/treatment Phase
Advanced Solid Tumors Drug: HTI-1090 Phase 1

Detailed Description:
This is an open-label, dose escalation, phase I, study of HTI-1090 (also known as SHR9146), a small molecule that inhibits both indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO) - two enzymes that catalyze the oxidation of L-tryptophan (Trp) into kynurenine (Kyn), thereby interrupting the immune escape and the attainment of immunologic tolerance. Dose escalation will use a modified "3+3" design and continue until a MTD or RP2D is identified. This study will also characterize the safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of HTI-1090 in subjects with advanced solid tumors.

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

To be eligible to participate in this study, each subject must meet all of the following criteria:

  1. Provision of signed fully informed consent prior to any study specific procedures
  2. Male or female aged 18 years or older
  3. Diagnosed (histologically or cytologically) with solid tumors and documented as advanced or metastatic disease for which there is no known effective anti-tumor treatment (refractory to or relapsed from standard therapies)
  4. Subjects may have received one prior IDO, or TDO, or IDO/TDO dual inhibitor therapy; PD-1 or PD-L1 inhibitor; or other therapy that targets T cell co-stimulation or co-inhibition more than 4 weeks prior to the first dose of HTI-1090 (Cycle 1, Day 1)
  5. An ECOG Performance Status (PS) of 0 or 1
  6. Have a life expectancy ≥ 12 weeks from proposed first dose date
  7. Patients must have had no recent major surgery, radiotherapy or chemotherapy over the past 28 days and be fully recover from toxicity before dosing
  8. Adequate laboratory parameters during the Screening Period as evidenced by:

    • Absolute neutrophil count ≥ 1.5×109/L (1,500/mm3)
    • Platelets ≥ 100×109/L (100,000/mm3)
    • Hemoglobin (Hgb) ≥ 9.0 g/dL (90 g/L)
    • Subjects may be transfused with red blood cells to improve Hgb levels.
    • Total bilirubin ≤ 1.5×ULN (≤ 2×ULN for subjects with liver metastases)
    • Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5×ULN; for subjects with liver metastases, ALT and AST ≤ 5×ULN
    • Serum creatinine ≤ 1.5 x ULN or creatinine clearance ≥ 50 mL/min (measured or calculated by Cockcroft-Gault method)
    • Clinically relevant and treatment resistant abnormalities in potassium, sodium, calcium (corrected for plasma albumin) or magnesium
  9. Evidence of post-menopausal status, permanent or surgically sterile, or negative serum pregnancy test for female patients of child-bearing potential. Women will be considered post-menopausal if they are over 50 years old and have been amenorrhoeic for 12 months or more following cessation of all exogenous hormonal treatments. Permanent sterilization includes hysterectomy and/or bilateral oophorectomy and/or bilateral salpingectomy but excludes bilateral tubal occlusion. Tubal occlusion is considered a highly effective method of birth control but does not absolutely exclude the possibility of pregnancy. (The term occlusion refers to both occluding and ligating techniques that do not physically remove the oviducts). Women who have undergone tubal occlusion should be managed as if they are of child-bearing potential (e.g., undergo pregnancy testing as required by the study). Females of reproductive potential are required to use reliable contraception
  10. Patients must have ability to take and retain oral medication and have no malabsorption problems
  11. Willing and able to return to treatment center for follow up, as outlined as protocol
