Trial Information

A Phase 1b/2a Safety and Pharmacokinetic Study of CRLX101 (Formerly Named IT-101) in the Treatment of Advanced Solid Tumors

Inclusion Criteria:

- Male and female subjects >18 years of age with advanced, histologically-confirmed
solid tumors refractory to standard therapy or for which no standard therapy exists
and who have evidence of disease progression documented since their prior therapy.

- Subjects must have measurable or evaluable disease.

- Subjects must not have received prior chemotherapy or radiation for >/= 4 weeks prior
to first dose of study drug.

- Subjects may be entered if they have received prior radiation therapy involving 30% of the bone marrow. Any prior radiation therapy must have been administered >/= 4
weeks prior to first dose of study drug and the subject must be recovered from the
acute toxic effects of the treatment prior to study entry.

- Subjects may be enrolled with a history of treated brain metastases that are
clinically stable for >/= 4 weeks prior to first dose of study drug. Subjects may
not be currently receiving dexamethasone.

- ECOG performance status of < 2.

- Life expectancy of greater than 12 weeks.

- Subjects must have acceptable organ and marrow function at screening and pre-dose

- Electrocardiogram without evidence of clinically significant conduction abnormalities
or active ischemia as determined by the investigator and an acceptable QTc interval.

- The effects of CRLX101 on the developing human fetus are unknown, therefore, women
of childbearing potential must agree to use adequate contraception prior to study
entry and for the duration of study participation.

- Ability to understand and the willingness to sign a written informed consent

Exclusion Criteria:

- Female subjects who are pregnant or nursing.

- Subjects who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for
nitrosoureas or mitomycin C) prior to first dose of study drug or those who have not
had adverse events return to baseline severity level or a severity level Grade 1 due
to agents administered more than 4 weeks prior to first dose of study drug.

- Subjects with a history of congestive heart failure (CHF) requiring medical therapy.

- Subjects with serum amylase or lipase > 1.5X upper limit of normal (ULN).

- Subjects with previous high dose chemotherapy with autologous stem cell rescue bone
marrow transplantation.

- Use of any investigational agent or drug within 4 weeks prior to first dose of study

- Metastatic disease to the CNS requiring treatment or radiation therapy.

- Subjects with known untreated brain metastases or treated brain metastases that have
not been stable >/= 4 weeks prior to first dose of study drug.

- Uncontrolled intercurrent illness including, but not limited to ongoing or active
infection, symptomatic congestive heart failure, hypertension, unstable angina
pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would
limit compliance with study requirements, as determined by the investigator.

- The presence of active coagulation disorder.

- Subjects with marked baseline prolongation of QT/QTc interval (QTc interval >/= 470
msec for females and QTc interval >/= 450 msec for males).

- Any prior treatment with a topoisomerase I inhibitor.

- Any major surgery
- Concurrent use of G-CSF or growth factors at the time of initiation of study drug.
