Abstract
Objectives:
Primary objective (Phase 1)
To evaluate the maximum tolerated dose (MTD)  and safety of TPI 287 administered 
once every three weeks in patients with refractory or recurrent breast cancer metastatic 
to the brain
Primary objective (Phase 2):  
To estimate the efficacy of TPI 287 by assessing the overall response rate [ORR (CR + 
PR)] of recurrent brain metastases using the McDonald Criteria.
Secondary objectives (Phase 1 and 2):
a.
To evaluate response duration of breast brain metastases on  TPI 287
b.
To evaluate rate and duration of the clinical benefit (CR+PR+SD)
c.
To assess activity of TPI 287 on extracranial metastatic disease
d.
To measure median progression free and overall survival of patients with metastatic
breast cancer treated with TPI 287
Rationale: (Be as concise as possible)
The current study proposes to examine a novel microtubule inhibitor TPI 287 that has 
shown potency and efficacy in a number of taxane sensitive and resistant tumors in

both preclinical and clinical studies.  TPI 287 has also been shown to be very well 
tolerated and exhibits limited myelosuppression at the currently employed doses.  It has 
also been shown that IV TPI 287 can penetrate the brain parenchyma to reach 
pharmacologically and clinically relevant levels, which suggests that breast cancers 
metastatic to the brain would be an appropriate target for therapy.  There is a significant 
amount of human safety data for TPI 287 with over 100 adult patients and now 5 
pediatric patients who have received drug in prior clinical trials to adequately assess the 
safety of the clinical trial and the dosing regimen for TPI 287 planned. 
A brain-tropic derivative of the MDA-MB-231 “triple negative” breast cancer cell line, 
231-BR, has been used to test the efficacy of drugs administered systemically to mice 
with nascent and established brain tumors.  In this assay, paclitaxel, ixabepilone and 
abraxane (all microtubule inhibitors) did not have significant inhibitory activity. TPI-287 
at 18 mg/kg delivered on days 3, 7 and 11  significantly reduced the outgrowth of brain 
metastases (55% reduction, p=0.028), and reduced proliferation in brain metastases 
(16% reduction, p=0.008).  Based on the results of this preclinical model, the utility of 
TPI 287 for the treatment of breast cancer metastatic to the brain is being explored in 
the clinical setting in this current protocol. 
In a recent clinical pilot study in glioma patients at MD Anderson Cancer Center dosing 
at 185 mg/m2 once every three weeks in combination with Avastin showed no dose 
limiting toxicity. In the initial version of this study, TPI 287 administered at a dose of 
125 mg/m2 showed no evidence of any toxicity when administered weekly for three out 
of every four weeks.  However, since it was also suggested by other Phase 2 studies 
that higher concentrations administered once every three weeks may provide greater 
efficacy, this amendment provides for a higher starting dose to explore the MTD on this 
schedule and then to evaluate efficacy.

This is an open label, Phase 1/2, exploratory trial evaluating the efficacy and safety of 
TPI 287 in patients with refractory or recurrent brain metastases from breast cancer.
During Phase 1, the dose of TPI 287 will be escalated in sequential dose cohorts 
(inter-cohort dose escalation).  TPI 287 will be administered at an initial dose of 160 
mg/m^2 as a 60-minute (± 10 minutes) intravenous (IV) infusion once every three weeks 
(i.e., 1 cycle = 21 days).  If patients enrolled at this dose have no dose limiting toxicities 
(DLTs) within 21 days of receiving the first dose of study drug, additional patients will be 
enrolled in subsequent cohorts of 3 patients at 20 mg/m2 increments (180 mg/m^2, 200 
mg/m^2, 220 mg/m^2, etc.) to explore a maximum tolerated dose (MTD) on this 
schedule for this patient population.  If patients experience DLT at the starting dose, one 
dose level below (Level -1) is also proposed.
If 1 out of 3 patients experiences a DLT within 21 days of receiving the first dose of 
study drug, an additional 3 patients will be enrolled in that cohort.  If >/= 2 patients at 

2010-0198

Abstract - Page 5
any dose level experience DLT within 21 days of receiving the first dose of study drug, 
the MTD will be the previous dose level tested.  
The MTD determination will be based on the number of patients that experience DLTs 
within 21 days of receiving the first dose of study drug.  DLTs will be considered to be 
any hematologic toxicity >/= Grade 3 within 21 days of receiving the first dose of study 
drug that does not recover within 3 weeks or any non-hematological toxicity >/= Grade 3 
within 21 days of receiving the first dose of study drug that does not improve to Grade 1 
or baseline within 3 weeks
Patients on the Phase 2 portion of the study will be enrolled at the MTD determined 
during Phase 1.  Initially, 25 patients will be enrolled in the Phase 2 portion of the trial; if 
at least 5 patients are shown to have an objective response, an additional 26 patients 
will be enrolled.
Patients may continue treatment in the study at any dose until intracranial disease 
progression or death, unacceptable toxicity, withdrawal of consent, or discontinuation 
based on Investigator discretion.  Patients will be followed for survival for up to 1 year 
after enrollment on the study.
Intra-patient dose escalation will be allowed for patients with extracranial progressive 
disease as long as the response of intracranial disease is stable or better and there is 
no unacceptable toxicity.  Only one dose escalation will be allowed per patient.  The 
dose will be escalated to the next higher dose level (20 mg/m^2 increase); under the 
condition that this higher dose level was previously shown to be safe per the 
inter-cohort dose escalation criteria.

Statistical Considerations:
This is an open label, Phase 1/2, exploratory trial evaluating the efficacy and safety of 
TPI 287 in patients with refractory or recurrent brain metastases from breast cancer.
The primary objective of the Phase 1 portion of the study is to determine the 
MTD of TPI 287 and in the Phase 2 portion of the study whether TPI 287 can 
provide clinical benefit for patients with metastatic breast cancer to the brain 
following failure of prior therapy, as measured by overall response rate. 
TPI 287 will be administered intravenously at an initial dose of 160 mg/m2 once 
every three weeks.  Dose escalation will continue in cohorts of 3 patients who will 
receive increasing doses until 1 out of 3 experience a dose limiting toxicity (DLT) 
at which time an additional 3 patients will be added at that dose.  If >/=2 patients 
experience a DLT, the MTD will be considered the prior dose level.  Dose levels 
will be 160 mg/m2, 180 mg/m2, 200 mg/m2 and then increased in 20 mg/m2 
increments until the MTD is reached.  
Once the MTD has been reached an initial cohort of 25 patients will be enrolled; 
if at least 5 patients are shown to have an objective response, an additional 26 
patients will be enrolled.
The following data sets will be used in this study:
•
All enrolled and eligible subjects (ITT) population: All eligible subjects who 
signed the informed consent form.
•
All treated and eligible patients (Safety and Efficacy evaluable) population: All 
patients who received at least one dose of study drug
Efficacy analyses will be performed on the Safety and Efficacy evaluable 
population in the patients on Phase 2. Safety analysis will be performed on the 
Safety and Efficacy evaluable population in both portions of the study.
The primary outcome measure will be response rate in the Phase 2 portion of the 
study. A  two-stage patient accrual plan is used for this portion. Based on 
historical data, responses to chemotherapy in this disease ranged from 
approximately 30 to 55%; however in most cases these were combined with 
whole brain radiation therapy. Therefore, a 15% response rate to single agent 

2010-0198

Abstract - Page 8
chemotherapy will be targeted as a reasonable outcome for this patient 
population.  We target this response rate of 15% because our experience in this 
heavily pre-treated patient population indicates that almost none of the patients 
of the patients will respond under the current best-supportive care/hospice care 
regimen.  We used trial and error to get a two-stage design with reasonable 
operating characteristics for p0 = 15%.  One such design would have 25 patients 
in the first stage and 26 patients in the second stage.  It would continue onto the 
second stage if more than 4 patients had response in the first stage.  The trial 
would be considered a success if 11 or more out of the total 51 patients had 
response.  This trial has a false positive (alpha) rate of 11% (under p0 = 15%) 
and a false negative (beta) rate of 12% (under p1 = 30%).  The trial also has a 
probability of early termination under p0 (i.e., if the true response probability is p0 
= 15%) of 68%.
