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

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

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.
