Trial Information

An Open-Label Phase Ib Continuation Study of Lapatinib Monotherapy or Lapatinib in Combination With Other Anti-Cancer Treatment in Patients With Solid Tumors

Inclusion Criteria:

- Participation in a Phase I lapatinib trial that has met its study objectives.

- Ability to understand and provide written informed consent to participate in this

- Male or female greater than or equal to 18 years of age.

- A female subject is eligible to participate if she is of:

- Non-childbearing potential defined as pre-menopausal females with a documented tubal
ligation or hysterectomy; or post-menopausal defined as 12 months of spontaneous
amenorrhea. Females on hormone replacement therapy (HRT) and whose menopausal status
is in doubt will be required to use one of the contraception methods stated in the
protocol if they wish to continue their HRT during the study. Otherwise, they must
discontinue HRT to allow confirmation of post-menopausal status prior to study
enrollment. For most forms of HRT, at least two to four weeks will elapse between
the cessation of therapy and the blood draw; this interval depends on the type and
dosage of HRT. Following confirmation of their post-menopausal status, they can
resume use of HRT during the study without use of a contraceptive method.

- Child-bearing potential, has a negative serum pregnancy test at baseline, and agrees
to use one of the contraception methods listed in the protocol for an appropriate
period of time (as determined by the product label or investigator) prior to the
start of dosing to sufficiently minimize the risk of pregnancy at that point. Female
subjects must agree to use contraception from two weeks prior to the administration
of study drug and throughout the entire active study treatment period until four
weeks after the last dose of study medication.

Exclusion Criteria:

- Permanent discontinuation of lapatinib in the previous study due to intolerance or
treatment failure.

- Is a pregnant or lactating female.

- Is considered medically unfit for the study by the investigator as a result of the
medical interview, physical exam, or baseline investigations.

- Currently receiving treatment with any medications listed on the prohibited
medication listed in the protocol

- Has Class III or IV heart failure as defined by the New York Heart Association (NYHA)
functional classification system.

- Have current active hepatic or biliary disease (with exception of subjects with
Gilbert's syndrome, asymptomatic gallstones, liver metastases or stable chronic liver
disease per investigator assessment).
