- Subjects who are of childbearing potential must have a negative serum pregnancy test at Screening and within 72 hours before the first dose.
- Subjects who have received recent anti-cancer therapy defined by:

- Subjects receiving luteinizing hormone-releasing hormone (LHRH) agonists may be considered for enrollment after discussion with the Sponsor.

- Subject who have impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of study drugs (including gastric bypass surgery and total gastrectomy).
- Subjects who have undergone major surgery (eg, intra-thoracic, intra-abdominal or intrapelvic), open biopsy or significant traumatic injury ≤28 days prior to starting study treatment, or subjects who have had minor procedures, percutaneous biopsies or placement of vascular access device ≤7 days prior to starting study drug, or who have not recovered from side effects of such procedure or injury
- Subjects with congenital long QT syndrome
- Uncontrolled concurrent illness, including but not limited to ongoing or active serious infection requiring systemic antimicrobials (within 14 days prior to first dose), uncontrolled arterial hypertension (>160/100 mm/Hg on antihypertensive medications), chronic pulmonary disease requiring oxygen, known bleeding disorders, uncontrolled endocrine diseases, altered mental status or psychiatric illness/social situations that would limit compliance with protocol requirements.
- Known or suspected diagnosis of human immunodeficiency virus (HIV) or chronic active Hepatitis B or C, or cirrhosis.

- Clinically significant arrhythmias (except chronic well controlled atrial fibrillation)
- New York Heart Association (NYHA) Class III or IV congestive heart failure
- Unstable angina pectoris within the last 6 months
- Myocardial infarction within the last 6 months
- Subjects with a healing or open wound
- Lack of recovery of prior AEs to Grade ≤1 severity (National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events [CTCAE] v4.03)3 (except alopecia or lymphopenia) due to medications administered prior to the first dose of the trial drugs.
- Any other condition or finding (including social situation) that in the opinion of the Investigator may render the patient at excessive risk for treatment complications or may not be able to provide evaluable outcome information.
- Pregnant or breast-feeding women
- Known allergy to any of the formulation components of Eribulin ORA
- Currently taking following prohibited concomitant medication:
- Strong cytochrome P450 (CYP) 3A4 inducer (eg, rifampin or St. John's Wort) or a strong CYP3A4 inhibitor (eg, ketoconazole) within 14 days prior to treatment administration
- Medication known to be strong P-gp inhibitors or inducers. Subjects who are taking such medications but who are otherwise eligible may be enrolled if they discontinue the medication 7 days before dosing and remain off that medication during treatment with Eribulin ORA.
- An oral medication with a narrow therapeutic index known to be a P-gp substrate (eg, digoxin, dabigatran, colchicine) within 1 day prior to start of Eribulin ORA dosing in the study
- Drugs known to prolong the QT interval, including Class Ia and III antiarrhythmics
This is a multicenter, open-label safety, tolerability, pharmacokinetic, and activity study.
Eligible subjects will be adults with advanced solid tumors.
Groups of 3 to 6 subjects will receive a single dose of Eribulin ORA on Day 1 and Day 8 of a
21 day cycle and will be followed for toxicity. If non linearity in PK is observed,
additional subjects will be added with study drug administered on Day 1 and 8 once every
three weeks cycle. Subjects who tolerate the study drug and have stable disease or better
response will be eligible to receive ongoing treatment.
