Phase I Study of Intravenous Lipotecan® (TLC388 HCl for Injection) in Patients With Advanced Solid Tumors

Lipotecan® is a drug product of TLC388 HCl, which is a potent camptothecin analog with
cytotoxic activities against a variety of human tumor cell lines in vitro and anti-tumor
activities in several xenograft models with human tumor cell lines. Structurally, TLC388 HCl
is related to other camptothecins, but it has been chemically modified to improve stability
and potency, and to minimize toxicities.

Inclusion Criteria:

- Adult patients defined by age ≥18 years.

- Pathologically confirmed advanced solid tumors for which standard therapy proven to
provide clinical benefit does not exist or is no longer effective

- Evaluable disease, either measurable on imaging or with informative tumor marker(s),
by RECIST (Response Evaluation Criteria in Solid Tumors) criteria.

Exclusion Criteria:

- Pregnancy or lactation. Women of childbearing potential must have a negative pregnancy
test within 7 days prior to enrolment. Male and female patients of childbearing
potential must agree to use appropriate birth control (barrier methods with
spermicides, oral or parenteral contraceptives and/or intrauterine devices) during the
entire duration of the study, or the patient must be surgically sterile (with
documentation in the patient's medical records).

- Previous malignancy, except for non-basal-cell carcinoma of skin or carcinoma-in-situ
of the uterine cervix, unless the tumor was treated with curative intent more than 2
years prior to study entry.

- Receipt of more than 3 prior regimens of chemotherapy.

- Chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C)
prior to baseline. Receipt of radiotherapy to >25 % of bone marrow. Major surgery
within 4 weeks prior to baseline.

- Concomitant treatment with, or anticipated use of, pharmaceutical or herbal agents
which are potent inhibitors or inducers of cytochrome P450 enzymes unless approved by
the Sponsor.

- Uncontrolled intercurrent illness that would jeopardize patient safety, interfere with
the objectives of the protocol, or limit patient compliance with study requirements,
as determined by the Investigator.
