A Phase I Study of TL32711 In Combination With Gemcitabine in Patients With Advanced Solid Tumors


PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) and recommended Phase II dose of TL32711
(smac mimetic TL32711) in combination with gemcitabine (gemcitabine hydrochloride) in
patients with advanced solid tumors.

SECONDARY OBJECTIVES:

I. To determine the toxicity and safety profile of TL32711 in combination with gemcitabine
in patients with advanced solid tumors.

II. To determine the pharmacokinetic profile of TL32711 and gemcitabine when administered in
combination.

III. To determine the preliminary efficacy of the study combination in patients with
advanced solid tumors.

IV. To determine the relationship between predictive biomarkers and clinical activity using
archival tumor tissue samples for biomarker analysis.

OUTLINE: This is a dose-escalation study of smac mimetic TL32711.

Patients receive gemcitabine hydrochloride intravenously (IV) over 30 minutes and smac
mimetic TL32711 IV over 30 minutes once weekly for 2 weeks. Courses repeat every 21 days in
the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for at least 4 weeks.

metastatic that gemcitabine-based treatment is considered standard therapy

available

hours prior to dosing)

alanine aminotransferase (ALT)/serum glutamate pyruvate transaminase (SGPT) =< 3 x
Upper Limit of Normal (ULN); In patients with known hepatic involvement, AST and ALT
< 5 x ULN are allowed

- Total bilirubin =< 1.5 x ULN; in patients with known hepatic involvement, total
bilirubin =< 1.5 x ULN is allowed

- Serum creatinine =< 1.5 x ULN, or 24-hr urine creatinine clearance calculation >= 60
mL/min

- Willing and able to comply with scheduled visits, treatment plan and laboratory tests

- Ability to understand and willingness to sign a written informed consent; a signed
informed consent must be obtained prior to any study specific procedures

- Women of childbearing potential must have a negative serum pregnancy test at
screening and negative (serum or urine) pregnancy test within 48 hours prior to the
first dose of the first cycle of study treatment

- Women of childbearing potential must agree to use 2 methods of adequate contraception
(i.e., hormonal and barrier method) prior to enrollment, during the study, and for a
period of 30 days following the last dose of study drug(s); males who are sexually
active must agree to use a condom during the study for a period of 30 days following
the last dose of study drug(s), and if their partner is of childbearing potential,
she must agree to use a secondary method of contraception (i.e., hormonal,
intrauterine device, barrier) during the study and for a period of 30 days following
the last dose of study drug(s)

Exclusion Criteria:

- Patients who have receive recent anti-cancer therapy defined by:

- Chemotherapy, immunotherapy, hormonal therapy and monoclonal antibodies (but
excluding nitrosourea, mitomycin-C, targeted therapy and radiation) =< 4 weeks prior
to starting study drug, or who have not recovered from side effects of such therapy

- Last administration of nitrosourea or mitomycin-C =< 6 weeks prior to starting study
drug, or who have not recovered from the side effects of such therapy; or

study drug, or who have not recovered from the side effects of such therapy; or

- Radiotherapy =< 4 weeks prior to starting study drug, or =< 2 weeks prior to starting
study drug in the case of localized radiotherapy (e.g. for analgesic purpose or for
lytic lesions at risk of fracture), or who have not recovered from radiotherapy

biopsies or placement of vascular access device =< 1 week prior to starting study
drug, or who have not recovered from side effects of such procedure or injury

- Uncontrolled concurrent illness, including but not limited to ongoing or active

dose of TL32711), arterial hypertension (> 160/100 mm/Hg on antihypertensive
medications), uncontrolled endocrine diseases, altered mental status or psychiatric

any requirement for supplemental oxygen, or pulse oximetry less than 90% saturation
on room air

- Symptomatic or uncontrolled brain metastases requiring current treatment (less than 4
weeks from last cranial radiation or 4 weeks from last steroids)
