Criteria

Inclusion Criteria:

1. Have given written informed consent prior to any study specific procedures

2. Male or female subject ≥ 18 years

3. Histologically/cytologically confirmed, unresectable locally advanced or metastatic solid tumors that are refractory to standard therapy or for which no standard therapy exists. Note for patients with non-small cell lung cancer [NSCLC] and patients with activating ALK translocation, or EFGR mutations must have been treated and failed appropriate targeted treatment).

Subjects enrolled in cohort expansion at MTD should have specific tumor types as below:

• KRAS mutant NSCLC confirmed by a documented historical report

• Breast cancer previously treated with a CDK4/6 inhibitor

4. All subjects should have evaluable disease as per RECIST 1.1 (Eisenhauer, 2009).

Subjects enrolled in cohort expansion at MTD should have measurable disease (presence of at least one measurable lesion) as per RECIST 1.1.

5. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) ≤ 1

6. Subjects with life expectancy of ≥ 3 months

7. Subjects with central nervous system (CNS) metatases are eligible if clinically controlled that is defined as surgical excision/and or radiation therapy followed by 3 weeks of stable neurologic function and no evidence of CNS disease progression as determined by contrast-enhanced computer tomography (CT) and nuclear magnetic resonance imaging (MRI) within 3 weeks prior to the first dose of study drug.

8. Must have adequate organ function, including the following:

• Bone marrow reserve: absolute neutrophil count (ANC) ≥ 1.5 X 10 9/L; platelet count ≥ 100 x 10 9/L;hemoglobin ≥ 9g/dL or ≥ 5.6 mmol/L

• Hepatic: total bilirubin ≤ 1.5 times the upper limit of normal (ULN), aspartate transaminase (AST) and/or alanine aminotransferase (ALT) ≤ 2.5 times ULN (< 5 times ULN if liver metastases).

• Renal: estimated creatinine clearance ≥ 45 mL/min based on the Cockcroft-Gault equation (Appendix 19.4).

• Coagulation: INR < 2.0, activated partial thromboplastin time (aPTT) ≤ 1.5 x ULN.

9. Subjects are able to swallow capsules.

10. Subjects (women of child-bearing potential and males) should be willing to use viable contraception method that is deemed effective by the Investigator throughout the treatment period and for at least 3 months following the last dose of study drug. Postmenopausal women must have been amenorrheic for at least 12 months to be considered of non-childbearing potential.

Exclusion Criteria:

1. Females during pregnancy or breastfeeding.

2. Subjects on any anticancer therapy approved or experimental, including chemotherapy, immune therapy, radiation therapy, hormonal therapy (Exceptions: hormone-replacement therapy, testosterone or oral contraceptives), biologic therapy, within 3 weeks (or 5 half-lives whichever is shorter) prior to initiation of study treatment. Note: Subjects should be recovered from treatment related toxicity resolved to baseline except for residual alopecia.

3. Subjects who had prior treatment with a CDK4/6 inhibitor except Hormone receptor (HR)+/Human epidermal growth factor receptor 2 (HER2)- breast cancer patients who may have received CDK4/6 inhibitor as a standard treatment.

4. Subjects with history of gastric bypass surgery or banding procedure.

5. Subjects who have had major surgery within the 28-days from the screening or subjects who have undergone organ transplant surgery.

6. Active hepatitis B (HBV) or hepatitis C (HCV). HBV carriers without active disease (HBV DNA titer < 1000 cps/mL or 200 IU/mL), or cured HCV (negative HCV RNA test) may be enrolled. Subjects with controlled human immunodeficiency virus (HIV) disease may be eligible.

7. Subjects with a concomitant medical condition that would increase the risk of toxicity, in the opinion of the Investigator or Sponsor.

8. Unresolved toxicities (other than alopecia) from previous anti-cancer therapy defined as toxicities not resolved to NCI CTCAE Version 5.0, Grade ≤ 1.

9. Subject who have had severe infection within 4 weeks or signs and symptoms of any active infection within 2 weeks prior to the first dose administration.

10. Severe or uncontrolled cardiac disease requiring treatment, congestive heart failure New York Heart Association (NYHA) III or IV, unstable angina pectoris even if medically controlled, history of myocardial infarction during the last 3 months, serious arrhythmias requiring medication (with exception of atrial fibrillation or paroxysmal supraventricular tachycardia).

11. A resting ECG with QTcF ≥ 470 msc or the subject has a congenital prolonged QT syndrome or with concomitant medications known to prolong the QT interval.

12. Taking a prohibited concomitant medication or inability to follow concomitant medications guidelines

13. Any other serious underlying medical (e.g., uncontrolled diabetes mellitus, uncontrolled hypertension, active uncontrolled infection, active gastric ulcer, uncontrolled seizures, severe hearing impairment, cerebrovascular incidents, gastrointestinal bleeding, severe signs and symptoms of coagulation and clotting disorders, cardiac conditions), psychiatric, psychological, familial or geographical condition that, in the judgment of the Investigator, may interfere with the planned staging, treatment and follow-up, affect subject compliance or place the subject at high risk from treatment-related complications.
