A Phase 1/2, Open-Label, Dose-Escalation Study of JI-101, in Patients With Advanced Solid Tumors

A Multicenter, Phase 1/2, Open-Label, Dose-Escalation Study of JI-101, an Oral Angiogenesis Inhibitor, in Patients With Advanced Solid Tumors

The purpose of this study, the first clinical trial of JI-101, is to determine the maximum tolerated dose of JI-101 when given orally to patients with solid tumors. Safety, tolerability, pharmacokinetics, pharmacodynamics, and the effects of the drug on tumor metabolism will also be studied. JI-101 is an inhibitor of new blood vessel growth that may provide benefit to patients with solid tumors that have failed standard therapeutic regimens.

Study Overview

• Status: Completed
• Conditions: Advanced Solid Tumors
• Intervention / Treatment: Drug: JI-101

Detailed Description

JI-101 is a compound being developed for the treatment of patients with solid tumors; specifically patients for which no approved therapy or standard of care is available or have solid tumors and have failed standard of care therapy. JI-101 is an inhibitor of vascular endothelial growth factor receptor 2 (VEGFR2), platelet-derived growth factor receptor beta (PDGFRβ), and EphB4 receptor, each of which plays an important role in driving vascularization (angiogenesis and vasculogenesis) during normal development and tumorigenesis. JI-101 inhibits the growth of new blood vessels, which in turn, may slow or prevent the growth of tumors. The purpose of this open label study is to treat patients with advanced solid tumors, with increasing doses of JI-101, thereby providing information about the maximum tolerated dose (MTD). The study will also examine safety, tolerability, pharmacokinetics, pharmacodynamics, and may evaluate the effects of the drug on tumor metabolism. During this dose-escalation study, at least two patients will be dosed at each dose level (cohort). The patients must complete 21 days of dosing and safety results will be reviewed prior to any patients being assigned the next higher dose level. A continuous reassessment method will be utilized to escalate JI-101 doses between cohorts. Doses will be increased, with an anticipated high dose of 800mg per day. If the MTD is not reached, an optimal biologic dose (OBD) will be determined based on the highest doses that are tolerable with acceptable efficacy. The cohort at MTD or OBD will be expanded to include up to 30 patients with solid tumors to further explore the safety and tolerability of orally-administered JI-101.

• No evidence of preexisting uncontrolled hypertension as documented by two baseline blood pressure readings taken at least 1 hour apart (the baseline systolic blood pressure readings must be <140 mm Hg, and the baseline diastolic blood pressure readings must be <90 mm Hg. Patients whose hypertension is controlled by antihypertensive therapies are eligible)
• Have no clinically significant disease that poses a risk to the patient and/or would interfere with study evaluations or procedures.
• Have within normal range cardiac function as measured by twelve-lead electrocardiogram at Screening.
• Be clinically euthyroid.
• If female, must be postmenopausal (at least 1 year from last menses), or surgically sterile, or if a female patient of childbearing potential they must agree to use acceptable methods of birth control, which include local double-barrier contraceptive methods, such as cervical diaphragm plus spermicide, female condom plus spermicide, or a non-hormonal intrauterine device (IUD) plus spermicide, or systemic contraceptive methods, such as oral, injectable, transdermal or implantable hormonal contraceptives (including hormone-containing IUDs) during the study period, and for 30 days after the last dose of study drug. Female patients of childbearing potential must have a negative serum pregnancy test within the 3 days before the first study drug administration. Male patients must be surgically sterile or also agree to use acceptable methods of birth control with their female partners, and this may include use of a male condom plus spermicide. If the subject is practicing abstinence at the time of Screening, he/she must agree to use a double-barrier contraceptive method if he/she becomes sexually active.
• Be able to understand and the willingness to sign a written informed consent document.

Exclusion Criteria:

• Be pregnant or breastfeeding.
• Have a known history of human immunodeficiency virus (HIV) infection because the effect of JI-101 on immunosuppression and drug interactions with anti-retroviral medications is unknown.
• Have participated in an investigational drug/device/biologic study within 30 days (or within 5 half-lives of the treatment, whichever is longer) before Visit 1 or who are currently participating in another investigational drug/device/biologic study. Participation in non-interventional or observational studies is allowed.
• Have a history of cardiac abnormalities including: abnormal and clinically relevant ECGs; frequent palpitations or syncopal episodes; heart failure; hypokalemia; stroke; family history of Long QT Syndrome; acute myocardial infarction or ventricular tachyarrhythmia within the previous 12 months.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximum Tolerated Dose (MTD) of JI-101	The primary objective of this study was to determine the maximum tolerated dose (MTD) of JI-101 when administered orally in patients with advanced solid tumors. The MTD was established based on safety data from Cycle 1. Patients who completed 21 days of treatment in Cycle 1 were considered to have completed the study for the determination of MTD. Patients were eligible to continue treatment with JI-101 until they experienced disease progression or unacceptable treatment-related toxicity. Unacceptable treatment-related toxicity was defined as a clinically significant AE or abnormal laboratory value assessed as unrelated to disease progression, intercurrent illness, or concomitant medications, and that was attributed to JI 101.	28 days (1 cycle)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants Reaching Maximum Tolerated Dose	Number of participants withdrawn from study due to adverse events	Up to 112 days (up to four 28-day cycles) or longer if the patient is benefiting from treatment
Overall Clinical Response by Cycle	Stable disease: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum LD since the treatment started. Progressive disease: At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum of LD recorded since the treatment started or the appearance of one or more new lesions	Up to 112 days ( four 28-day cycles)
Days to Progression	Progression: At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum of LD recorded since the treatment started or the appearance of one or more new lesions	Up to 112 days (four 28-day cycles) or longer if the patient is benefiting from treatment
