and/or unresectable) thymic carcinoma, for which no curative treatment (including
surgery, radiation, or other) is available
- Have experienced progressive disease after at least one previous regimen of
platinum-based chemotherapy. Prior platinum-containing adjuvant, neoadjuvant, or
definitive chemoradiation therapy given for locally advanced disease is considered
first line therapy only if recurrent (local or metastatic) disease developed within 6
months of completing therapy. Subjects with recurrent disease < 6 months will be
eligible. Patients who have not had prior platinum-based chemotherapy for documented
reasons (e.g., refusal or drug supply issues) may be eligible for study entry at the
discretion of the sponsor investigator.

a recently obtained archival FFPE tumor tissue block (if an FFPE tissue block cannot
be provided, 15 unstained slides [10 minimum] will be acceptable) from a primary or
metastatic tumor resection or biopsy can be provided if it was obtained within 3 years
of trial screening; patients with tumor specimens older than 3 years may still be
eligible if deemed so by study sponsor
- Be willing to provide tissue from an on-treatment fine-needle aspiration (FNA) or core
biopsy of a tumor lesion; subjects must consent to on-treatment biopsy prior to
initiation of clinical trial, however in subjects for whom newly-obtained samples
cannot be provided (e.g. inaccessible or subject safety concern) may still continue on
study

treatment initiation
- Albumin >= 2.5 mg/dL, performed within 28 days of treatment initiation
- International normalized ratio (INR) or prothrombin time (PT) =< 1.5 X ULN unless
subject is receiving anticoagulant therapy as long as PT or partial thromboplastin
time (PTT) is within therapeutic range of intended use of anticoagulants, performed
within 28 days of treatment initiation
- Activated partial thromboplastin time (aPTT) =< 1.5 X ULN unless subject is receiving
anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use
of anticoagulants, performed within 28 days of treatment initiation
- Female subject of childbearing potential should have a negative urine or serum
pregnancy within 72 hours prior to receiving the first dose of study medication; if
the urine test is positive or cannot be confirmed as negative, a serum pregnancy test
will be required
- Female subjects of childbearing potential must be willing to use an adequate method of
contraception for the course of the study through 120 days after the last dose of
study medication
- Note: abstinence is acceptable if this is the usual lifestyle and preferred
contraception for the subject

contraception starting with the first dose of study therapy through 120 days after the
last dose of study therapy
- Note: abstinence is acceptable if this is the usual lifestyle and preferred
contraception for the subject
Exclusion Criteria:

of an investigational agent and received study therapy or used an investigational
device within 4 weeks of the first dose of treatment
