Description
Inclusion Criteria:
Phase I Portion:
- Diagnosis of solid tumors on histopathological examination or cytological examination for which no standard of care is available or conventional treatment modalities have no therapeutic effect at the time of entering into the study

- Subjects with stomach cancer without prior taxane therapy
- Subjects with breast cancer with prior taxane therapy
- (Optional) Providing exploratory biomarker informed consent form to obtain archival tumor tissue and/or new tumor biopsy sample
Common:
Based on clinical screening,
① If radiotherapy was given, at least 4 weeks should have passed from the last treatment date and the patient should have recovered from the toxicity (However, for limited regional radiotherapy, at least 2 weeks from the last treatment date)
② If hormonal therapy was given, at least 2 weeks should have passed from the last treatment date and the patient should have recovered from the toxicity.
③ If chemotherapy was given, at least 3 weeks should have passed from the last treatment date and the patient should have recovered from the toxicity (However, for nitrosourea or mitomycin, at least 6 weeks)
- Aged ≥ 20 years

Should meet the followings,
① Bone marrow function ANC (Absolute Neutrophil Count) ≥ 1.5 X 109/L, PLT (Platelet Count) ≥ 100 X 109/L, Hemoglobin ≥ 9.0 g/dl (In the case of hemoglobin of < 9.0 g/dl, the patient can be enrolled if the value is reversed to ≥ 9.0 g/dl.)

- Subjects who voluntarily consent to participate in this study and sign the written informed consent form
Exclusion Criteria:
- Uncontrolled central nervous system metastasis
- Malignant ascites requiring surgical treatment
- Subjects who have blood malignancies including leukemia; or who have received or will receive bone marrow transplantation
Severe concurrent diseases as follows,
① History of unstable angina, heart failure, atrial or ventricular arrhythmia requiring pharmacological treatment, or having received treatment for myocardial infarction within 6 months (however, may be included under the judgment of the investigator if medically controlled), heart failure of Class III or IV by New York Heart Association Classes, or left ventricular ejection fraction of < 40%
② Receiving therapeutic dose administration of coumarin-type anticoagulants (however, up to 2 mg daily is permitted for line opening)
③ Uncontrolled diabetes (fasting plasma glucose > 2.0 X UNL), severe hypertension, thyroid disorder and active infectious disease
④ Psychiatric or neurological history including dementia or epilepsy which may threaten the compliance with this protocol
⑤ A condition not allowing oral application of tablet formulation, and any clinically significant gastrointestinal abnormalities which may interfere with taking, passing or absorption of the study drug
- Using disallowed concomitant medications (strong CYP3A4 (Cytochrome P450 3A4) inhibitors or inducers) (When a patient is using any of the disallowed concomitant medications below, wash-out of 1 week from the medication date is required)
- Received other investigational product within 4 weeks prior to the administration of this study drug
- Pregnant or breast-feeding women (however, women with 12 months of natural (spontaneous) amenorrhea or surgical bilateral oophorectomy (alone or with hysterectomy) at least 6 weeks ago, with appropriate clinical profile (e.g., appropriate age, history of vasomotor symptoms), will be considered women postmenopausal and of non-childbearing potential. In the case of oophorectomy alone, a woman will be considered to be of non-childbearing potential only if her reproductive condition is confirmed by follow-up hormone level assessment)
- History of hypersensitivity to paclitaxel, compounds with similar chemical structure, or cremophor (polyoxyethylated castor oil) ingredient
- Neuropathy of grade ≥ 3 based on clinical screening
- Known history of hepatitis B or C and known history of HIV serum positive
- Others unable to participate in the study under the judgment of the investigator

Intervention / Treatment |
---|---|
Experimental: KX2-391 and Paclitaxel
The phase I portion is a standard, three-patient per cohort, dose escalation schedule will be used. 3 or 6 subjects with solid tumor per dose group will likely be necessary to determine the MTD of KX2-391 in combination with weekly paclitaxel. With paclitaxel dose fixed at 80 mg/m2/weekly, KX2-391 treatment will be started at 20 mg dose once daily (QD) The phase II portion of this trial has a design to determine the efficacy of KX2-391 when administered in combination with paclitaxel in 20 subjects with stomach cancer and 20 subjects with breast cancer |
A treatment cycle in phase I will consist of 28 days, according to the following schedule: KX2-391 20 mg PO once daily, Weekly paclitaxel 80 mg/m2 given intravenously over 1 hour on day 1, 8, and 15 of a 28 day cycle. The trial will initially test the combination of weekly paclitaxel and KX2-391 given PO, once daily , continuously. In case of 2 dose-limiting toxicities (DLT) in the first cohort, this intervention will be terminated A treatment cycle in phase II will consist of 28 days, according to the following schedule: KX2-391 MTD PO once daily, Weekly paclitaxel 80 mg/m2 given intravenously over 1 hour on day 1, 8, and 15 of a 28 day cycle.
