Brief Summary
A Phase 1 randomized, double blinded, placebo-controlled, single dose escalation (SDE) and repeat dose escalation (RDE) study to evaluate safety and tolerability, and PK of KDR2-2 in healthy volunteers. The planned single dose levels are 0.03, 0.06, 0.12, and 0.24 mg/eye, and repeat dose levels are 0.06, 0.12, and 0.24 mg/eye, QID, × 6 days (one dose in the morning on Day 7). Subjects are randomized to KDR2-2 or placebo dosing (6:2 for SDE, or 8:2 for RDE) in each cohorts of relative dosing levels.

PLACEBO COMPARATORSubjects will receive placebo (drops without drug).
Interventions
KDR2-2 is a synthetic anti-angiogenic chemical compound with highly effective inhibition on vascular endothelial growth factor receptor-2 (VEGFR2), and an additional, moderate inhibitory effect on platelet-derived growth factor receptor β (PDGFRβ). KDR2-2 suspension eye drop is in development for the treatment of corneal neovascularization.
Placebo : the formulation and the product process of placebo are the same as the KDR2-2 eye drops, but without API .
Eligibility Criteria
You may qualify if:
- Subjects must meet all the following criteria to be enrolled in the trial:
- Able to understand and willing to sign the ICF
- Healthy male and female subjects, non-smokers, 18-55 years of age
- With no significant medical history, and in good health as determined by detailed medical history (neurological, endocrinal, cardiovascular, pulmonary, hematological, immunologic, psychiatric, gastrointestinal, renal, hepatic, and metabolic disease), full physical examination, vital signs, 12-lead electrocardiogram (ECG), urinalysis and laboratory tests at screening. For eligibility purposes, abnormal laboratory or vital signs results may be repeated once if abnormal result is observed at the initial reading. Moreover, abnormalities found in the ECG may need to be confirmed by repeated measurements.
- Subjects must have adequate organ function according to the following laboratory values at Screening and on Day-1. Repeat testing is allowed for verification, at the discretion of the Investigator:
- Bone marrow function (absolute neutrophil count ≥ 1500/mm3 and platelet count ≥ 100,000/mm3)
- Adequate liver function \[alanine aminotransferase (ALT) ≤ 1.5 × upper limit normal (ULN) and alkaline phosphatase ≤ 1.5 × ULN, total bilirubin ≤ 1.5 mg/dL\]
- Adequate renal function creatinine clearance 60 mL/min based on Cockcroft - Gault equation, or serum creatinine level ≤ 1.5 times the ULN.
- Be a female of non-childbearing potential (i.e., physiologically incapable of becoming pregnant, including any female who is 2 years post-menopausal and have an FSH \> 40 mIU/mL, or surgically sterile \[defined as having a bilateral oophorectomy, hysterectomy or tubal ligation\]) or agree to one of the following to prevent pregnancy and, if a woman of childbearing potential, have a negative serum pregnancy test at screening:
- If a sexually active woman of childbearing potential (sexually active with a non-sterile male partner) agrees to prevent pregnancy by using double methods of contraception as follow until at least 30 days after the administration of the investigational product:
- simultaneous use of intra-uterine contraceptive device, placed at least 4 weeks prior to study drug administration, and condom for the male partner;
- simultaneous use of hormonal contraceptives, starting at least 4 weeks prior to study drug administration and must agree to use the same hormonal contraceptive throughout the study, and condom for the male partner;
- simultaneous use of diaphragm with intravaginally applied spermicide and male condom for the male partner, starting at least 7 days prior to study drug administration.
- Male subjects who are not vasectomized for at least 6 months and who are sexually active with a non-sterile female partner must agree to use double methods of contraception below from the first dose of randomized study drug until 7 days after their dose and must not donate sperm during their study participation period:
- simultaneous use of a male condom and, for the female partner, hormonal contraceptives (used since at least 4 weeks) or intra-uterine contraceptive device (placed since at least 4 weeks);
- +4 more criteria
You may not qualify if:
- Subjects who meet any of the following criteria cannot be enrolled:
- History of severe infection within 4 weeks prior to administration; signs and symptoms of any active infection regardless of severity within 2 weeks prior to administration.
- History of eye infection, or trauma or surgeries including LASIK.
- Subjects with a single eye.
- History of hypersensitivity to similar drugs to KDR2-2 or their excipients.
- Clinically significant abnormalities on ocular examination, including slit lamp, that would hinder the assessment of the eye or data collection at the discretion of the Investigator and/or ophthalmologist.
- Any corrected visual acuity \< 20/20, or intraocular pressure ≥ 20 mmHg.
- Subjects who wear contact lenses within 1 month prior to administration, or will wear contact lenses during the trial.
- Participation in a clinical research study involving the administration of an investigational or marketed drug or device within 30 days prior to the first dosing, administration of a biological product in the context of a clinical research study within 90 days prior to the first dosing, or concomitant participation in an investigational study involving no drug or device administration.
- Donation of blood 12 week prior to dosing.
- Pregnant, or nursing females.
- A history of psychiatric and psychological condition that, in the judgment of the investigator, may interfere with the planned treatment and follow-up, affect subject compliance or place the subject at high risk from treatment-related complications
- A marked baseline prolongation of QT/QTc interval (e.g., repeated demonstration of a QTcF interval \> 450 milliseconds \[ms\], Bazett Formula: QTc = QT/RR0.5)at Screening and on Day -1.
- Active hepatitis B or C. HBV carriers without active disease (HBV DNA titer \< 1000 cps/mL or 200 IU/mL), or cured Hepatitis C (negative HCV RNA test) may be enrolled, in the judgement of the investigator.
- Human immunodeficiency virus (HIV) positive.
