Brief summary:
The purpose of this study is to see if pralatrexate extends response and survival following CHOP-based chemotherapy (CHOP: cyclophosphamide, doxorubicin, vincristine, and prednisone) and if pralatrexate improves response in patients with partial response following CHOP-based chemotherapy. Patients will either receive pralatrexate or be under observation. All patients will receive vitamins B12 and folic acid and attend regular clinic visits to evaluate their disease and health.

Detailed description:
This was an international, multi-center, randomized, Phase 3, open-label study of sequential pralatrexate versus observation in patients with previously undiagnosed PTCL who have achieved an objective response following initial treatment with CHOP-based chemotherapy.

Upon documentation of completion of an objective response following at least 6 cycles of a designated CHOP-based chemotherapy confirmation of histopathology by independent review, and confirmation that all eligibility criteria were met, patients were randomized in a 2:1 ratio to either pralatrexate or observation, according to a permuted block design with stratification factor of Tumor Response per Investigator at completion of CHOP-based therapy (Complete Response \[CR\] vs Partial Response \[PR\]).

All patients who receive at least 1 dose of pralatrexate were followed for safety through 35 (± 5) days after their last dose of pralatrexate or until all treatment-related AEs have resolved or returned to baseline/Grade 1, whichever is longer, or until it was determined that the outcome does not change with further follow-up.

Arms:
arm 1: Patients randomized to the Pralatrexate Arm will receive pralatrexate injection and Vitamins B12 and Folic Acid until a criterion for pralatrexate injection treatment discontinuation is met. arm 2: Patients randomized to the Observation Arm will receive Vitamins B12 and Folic Acid and remain under observation until a criterion for observation discontinuation is met.

Interventions: intervention 1: Pralatrexate Injection
Intervention descriptions: intervention 1: Intravenous (IV) push administration over 30 seconds to 5 minutes via a patent IV line containing normal saline (0.9% sodium chloride).

Initial dose: 30 mg/m2

Administered weekly for 3 weeks of a 4-week cycle until criteria for discontinuation per the protocol are met.

PDX-017 Statistical Analysis Plan 
 
Version 1.2 
1 
INTRODUCTION 
The purpose of this statistical analysis plan is to provide details of the statistical analyses that 
have been outlined within version 2.1 of the protocol for pralatrexate study PDX-017 dated 
31 Oct 2011.  The scope of this plan includes the interim and final analyses.  The analyses 
detailed within this plan will help to evaluate the efficacy and safety of pralatrexate as 
sequential therapy in patients with peripheral T-cell lymphoma (PTCL) who have achieved 
an objective response following initial treatment of first-line cyclophosphamide, doxorubicin, 
vincristine, and prednisone (CHOP)-based regimen.

OBJECTIVES 
2.1 
Primary Objective 
Determine the efficacy of pralatrexate compared to observation when administered to 
patients with previously undiagnosed PTCL who have achieved an objective response after 
completing at least 6 cycles of CHOP-based treatment. 
2.2 
Secondary Objective 
Determine the safety of pralatrexate when administered following a course of CHOP-based 
treatment to patients with previously undiagnosed PTCL.

STUDY DESIGN 
This is an international, multi-center, randomized, Phase 3, open-label study of sequential 
pralatrexate versus observation in patients with previously undiagnosed PTCL who have 
achieved an objective response following initial treatment with CHOP-based chemotherapy. 
Upon documentation of an objective response following at least 6 cycles of a designated 
CHOP-based chemotherapy, confirmation of histopathology by independent review, and 
confirmation that all eligibility criteria are met, patients will be randomized in a 2:1 ratio to 
either pralatrexate or observation, according to a permuted block design (block sizes of 3) 
stratified by response per investigator at completion of CHOP-based therapy (complete 
response [CR] vs partial response [PR]). 
Patients randomized to the Pralatrexate Arm will receive pralatrexate as an intravenous (IV) 
push administration over a minimum of 30 seconds up to a maximum of 5 minutes via a 
patent free-flowing IV line containing normal saline (0.9% sodium chloride [NaCl])   
weekly for 3 weeks (± 1 day at each time point) of a 4-week cycle.  The initial dose of 
pralatrexate will be 30 mg/m2 which, based on protocol-defined criteria, may be reduced to 
20 mg/m2 with potential further reduction to 15 mg/m2 and 10 mg/m2.  There will be sparse 
sampling for pharmacokinetics (PK).  Pralatrexate will continue to be administered until a 
criterion for study treatment discontinuation is met or up to a maximum of 2 years.

Version 1.2 
Patients randomized to the Observation Arm will remain under observation, attend clinic 
visits every 4 weeks, and receive a follow-up phone call from a healthcare professional 
during each week 2 of 4 until a criterion for study treatment discontinuation is met for a 
maximum of 2 years. 
All patients will receive vitamin supplementation, consisting of vitamin B12 1 mg 
intramuscularly (IM) every (q) 8-10 weeks and folic acid 1-1.25 mg by mouth (po) once a 
day (qd).  Vitamin supplementation will begin at least 7 days prior to the projected initiation 
of pralatrexate/observation and continue throughout the study until the Initial Follow-up 
Visit. 
Patients will be followed for safety until 35 (± 5) days after the study treatment 
discontinuation criteria are met.  Patients will be followed to determine time to progressive 
disease (PD) and survival for up to 7 years from randomization or until 35 (± 5) days after 
the last dose of pralatrexate, whichever is longer.  Patients who withdraw from treatment 
prior to PD without withdrawing consent will be followed for disease status whenever 
possible, even if subsequent therapy, including transplant, has been initiated prior to 
documented PD per central review, at least until the first interim analysis. 
3.1 
Stratification Factors 
The randomization will be stratified by response per investigator at completion of 
CHOP-based therapy (CR vs PR). 
3.2 
Sample Size Considerations 
A total of approximately 549 randomized patients are planned for this study. 
Outcome data for patients with T-cell lymphoma who receive first-line CHOP are limited.  
A retrospective study of the International T-Cell Lymphoma Project demonstrated a 5-year 
overall survival (OS) rate of 32% and a 5-year failure-free survival (FFS) rate of 20% for 
patients with peripheral T-cell lymphoma unspecified (PTCL-U), with widely varying results 
for other subtypes.1  Median OS for these patients did not seem to be a function of whether 
the patient received an anthracycline-based induction therapy.  In a retrospective evaluation 
of 96 patients diagnosed within the Non-Hodgkin’s Lymphoma Classification Project, 
Rudiger et al  report a similar finding, with 5-year OS and FFS rates of 26% and 20%, 
respectively, for PTCL patients treated with a doxorubicin-containing regimen.2  Per Figure 1 
of the Rudiger publication, the estimated median FFS in these patients is approximately 
6 months.   
Reports of response rate to first-line CHOP-based regimens in patients with PTCL are also 
available.  Gallamini et al, conducted a small study (n = 24 evaluable) evaluating CHOP plus 
alemtuzumab administered every 4 weeks for a total of 28 weeks.3  They observed an overall 
response rate of 75% (71% CR, 4% PR).  In a separate report, Gallamini et al, performed a 
retrospective analysis of 385 patients with PTCL-U, with the majority (78%) receiving 
chemotherapy containing anthracycline.4  They reported an overall response rate of 
74% (53% CR, 21% PR) in the 372 evaluable patients.  Mercadal and colleagues reported on 
Confidential

Version 1.2 
a series of 41 patients ≤ 65 years old who were planned to receive 6 cycles of intensive 
chemotherapy (high-dose CHOP alternating with etoposide, methylprednisolone, cytarabine, 
and cisplatin [ESHAP]) followed by autologous stem cell transplantation if in response.5  
Twenty-eight patients (68%) received the planned 6 courses of therapy, 6 patients (15%) 
received 5 courses of therapy, and 7 (17%) received less than 5 courses.  Following the 
chemotherapy phase, the CR rate was 49% and the PR rate was 10%.  Kim and collaborators 
administered CHOP plus etoposide and gemcitabine to a cohort of 26 first-line PTCL 
patients.6  The median number of cycles administered was 4, and the overall response rate 
was 77% (62% CR, 15% PR).  Abouyabis and colleagues performed a meta-analysis of 
non-anaplastic large cell lymphoma (ALCL) PTCL patients receiving anthracycline-based 
chemotherapy in the first-line setting.7  A total of 31 studies were identified involving a total 
of 1996 patients.  The overall CR rate was 55% and the 5-year OS rate was 37%. 
Across all of these reported studies, approximately 50% of patients achieve a CR to first-line 
CHOP, with an additional 10-20% achieving a PR.  Furthermore, the 5-year progression-free 
survival (PFS) is approximately 20%, with a median PFS of approximately 9 months in all 
patients.  For sample size calculations for the PDX-017 study, we assume that one-third of 
these patients will have disease refractory to CHOP and that the median PFS in these patients 
will be 3 months.  Coupled with an overall median PFS of 9 months, and assuming 
exponentially distributed PFS, this implies the median PFS in patients who respond to CHOP 
is approximately 16 months.  Subtracting out 6 months for CHOP administration and 
washout prior to randomization results in an estimated 10-month median PFS for 
Observation Arm patients in PDX-017. 
The sample size is based on comparing the treatment groups with respect to the primary 
efficacy endpoints of PFS and OS.  Assuming proportional hazards, a true hazard ratio (HR) 
on OS of 0.73, and a 2:1 randomization (treatment:observation) with a total of 549 patients 
(366 in the treatment group vs 183 in the observation group), a total of 385 OS events 
(deaths) will provide at least 80% power to show HR < 1.00 using a 2-sided stratified 
log-rank test at a 0.05 significance level (alpha = 0.05), assuming an accrual period of 
54 months and a follow-up period of 30 months.  For a HR on PFS of 0.67, a total of 
280 PFS events (PD + deaths) will provide at least 80% power to show HR < 1.00 using 
a 2-sided stratified log-rank test at a 0.05 significance level. 
Further assuming that PFS is exponentially distributed, that the median PFS in the control 
group is 10 months, and that uniform enrollment will occur over 54 months, under the 
alternative hypothesis that HR = 0.67, the 280th event will occur approximately 48 months 
after the first patient is randomized.  Allos will set a data cut-off date for the primary efficacy 
analysis in anticipation of the 280th PFS event and 128th OS event. 
3.3 
Interim Analyses 
A step down procedure will be used for analyzing the co-primary endpoints of PFS and OS.  
If the PFS endpoint is significant at the 0.05 level the OS endpoint will be tested at an overall 
significance level of 0.05.  However, if the PFS endpoint fails to show significance, the study 
will be stopped and OS will not be tested.  The study will meet its primary objective if both 
Confidential

Version 1.2 
the PFS and OS endpoints are significant.  The interim analyses for OS will be implemented 
using the error-spending approach of Lan and DeMets according to the unified family 
approach with boundary relationships of O’Brien and Fleming for early stopping to reject the 
null hypothesis (superiority).8, 9  The boundaries for early stopping due to failure to reject the 
null hypothesis (futility) will be determined according to the unified family approach with 
boundary shape parameters on the sample mean scale that result from choosing P = 2.0 
(all R and A parameters in the unified family approach set equal to zero).10 
There will be 1 final analysis of PFS, and 2 interim and 1 final analyses of OS. The first 
interim analysis of OS will be performed at the same time as the PFS analysis.  The first 
interim analysis will be performed when both 280 PFS events and 128 OS events have 
occurred.  The only analysis for PFS will be performed at this first analysis point, at the 
0.05 level of significance.  If PFS is significant at the 0.05 level, the first interim analysis will 
be conducted on survival at this time.  If the PFS analysis is not significant at the 0.05 level, 
the study will be stopped.  If there are 128 OS events, or one-third of the information of 
385 deaths, included in the first interim analysis of OS, the level of significance (alpha) 
would be 0.0002, according to O’Brien and Fleming.8, 9  If PFS is significant, a test for 
futility of OS will not be conducted at the first interim analysis since such a result could not 
occur.  The second interim analysis for OS will be performed when two-thirds (256) of the 
survival events have occurred, at the 0.013 level of significance.  The HR stopping bound for 
futility at this interim analysis will be 1.05 (95% confidence interval [CI]: 0.80, 1.29).  If the 
HR for OS is greater than 1.05, the study will be stopped.  The final analysis for survival will 
be performed when 385 OS events have occurred, at the 0.046 level of significance.  
The stratified log-rank test (stratified by response to prior CHOP-based therapy) will be the 
primary method used to test the hypothesis that pralatrexate extends PFS and OS relative to 
observation.  In addition, the stratified Cox regression model will be used to calculate the 
PFS and survival hazard ratio (HR), along with their 95% CIs.  Results of the unstratified 
Cox regression model (and log-rank test) will also be presented.  The proportional hazards 
assumption of the Cox model will be assessed. 
Data Monitoring Committee 
A Data Monitoring Committee (DMC) will evaluate safety after approximately 100 patients 
have been randomized and have completed at least 8 weeks post-randomization 
pralatrexate/observation or have discontinued.  Safety evaluations will also be performed at 
the same time of each interim analysis of efficacy. All interim analyses will be performed by 
the DMC. 
At each interim analysis for survival, the DMC will make a recommendation to Allos to 
either stop or continue the study.  The study could be stopped for overwhelming evidence of 
superiority or futility according to specified boundaries.  At the first interim analysis for 
survival, the DMC could also make the recommendation to Allos to submit a regulatory 
filing based on positive results of the PFS endpoint plus a trend of survival in favor of the 
pralatrexate treatment group.  Allos may discuss the DMC’s recommendations with

regulatory authorities before any such action is taken.  The DMC may also make 
recommendations regarding adjustments to the sample size, if they are warranted.

STUDY ENDPOINTS AND COVARIATES 
4.1 
Primary Efficacy Endpoints 
The co-primary efficacy endpoints are PFS and OS. 
4.2 
Secondary Efficacy Endpoint 
The secondary efficacy endpoint is objective response (CR or PR) to pralatrexate versus 
observation. 
The primary analyses of PFS and objective response at the first interim analysis will use the 
central review of tumor assessments per International Workshop Criteria (IWC) without 
positron emission tomography (PET).  Additional analyses of PFS and objective response 
will use IWC, including PET, and investigators’ assessment of response.  Additional details 
regarding central review will be provided in the reviewer’s charter. 
4.3 
Safety Endpoints 
Safety endpoints include: 
• Incidence and severity of treatment-emergent adverse events (AEs). 
• Changes in laboratory values. 
4.4 
Potential Covariates 
The following covariates will be considered in covariate-adjusted and other exploratory 
analyses: 
• Stratification factor (CR vs PR to prior CHOP-based therapy); 
• The International Prognostic Index (IPI) score at initial diagnosis (plus individual 
components as collected); 
• Histology (PTCL-U vs transformed mycosis fungoides vs ALCL vs other); and 
• Region.

Definitions 
Screening Phase 
The screening phase is the period between signing of informed consent and randomization. 
Baseline 
For efficacy assessments, baseline is defined as the last assessment prior to randomization.  
For safety assessments, baseline is defined as the last assessment prior to study day 1. 
Study Day 1 
Study day 1 is defined as the treatment start date.  By convention, when known, assessments 
that occur on the same date as the treatment start date but that occur before treatment will be 
assigned as study day 0; those occurring in the same day but after treatment start will be 
assigned as study day 1.  For patients randomized to the Observation Arm, study day 1 will 
be assigned to all patients who do not withdraw from the study prior to 3 days post-
randomization, and will be equal to the randomization date plus 3 days. 
Cycle 
For patients randomized to the Pralatrexate Arm, a cycle will be calculated as the time from 
the first administration of pralatrexate for the given cycle to the day before the first 
administration of the subsequent cycle.  The last cycle for a patient will be calculated as the 
time from the first administration of protocol-specified treatment for the given cycle plus 
4 weeks or to the last dose administered within the cycle, whichever is longer. 
Complete Response 
CR is defined based on the IWC.11  The same imaging method(s) used to document disease 
pre-randomization are to be used for post-randomization response assessments. 
Partial Response 
PR is defined based on the IWC.11  The same imaging method(s) used to document disease 
pre-randomization are to be used for post-randomization response assessments. 
Objective Response 
Objective response is defined as a tumor response assessment of either CR or PR based on 
IWC.11  The same imaging method(s) used to document disease during screening are to be 
used for subsequent response assessments. 
Stable Disease 
SD is defined using IWC.11 
Confidential

Version 1.2 
Progressive Disease 
PD is defined using IWC.11 
Progression-free Survival Time  
PFS time is calculated as the number of days from randomization to the date of objective 
documentation of PD or death, regardless of cause (PD date/death date - date of 
randomization + 1).  Patients who are alive without a disease response assessment of PD will 
be censored at their last disease assessment date or the date of randomization, whichever is 
later.  Date of progression will not be imputed for patients with missing tumor assessment(s) 
before an assessment of PD.  Patients who withdraw from treatment prior to PD without 
withdrawing consent will be followed for disease status whenever possible, even if 
subsequent therapy, including transplant, has been initiated prior to documented PD per 
central review at least until the first interim analysis.  Patients who have not died and who 
have no response assessments after baseline will be censored at randomization. 
Overall Survival Time 
OS time is calculated as the number of days from randomization to death (date of death - date 
of randomization + 1).  Patients who have not died (no record of death) or are lost to 
follow-up will be censored at the date of last contact.  Patients who withdraw from study visit 
participation will be followed for survival status.  OS will be reported in months. 
Treatment-emergent Adverse Event 
A treatment-emergent AE is defined as an AE that occurs on or after study day 1 and that is a 
higher grade than was present just prior to study day 1.

ANALYSIS SUBSETS  
6.1 
Primary Analysis Set 
The primary efficacy set, also referred to as the intent-to-treat population or full analysis set 
(FAS), will include all randomized patients.  Each patient will be included in the treatment 
group assigned at randomization, regardless of the treatment received.  This analysis set will 
be used for the primary analyses of all efficacy endpoints. 
6.2 
Safety Analysis Set 
The safety analysis set consists of all patients randomized to the Pralatrexate Arm who 
receive at least 1 dose of pralatrexate plus all patients randomized to the Observation Arm 
who do not discontinue study within 3 days of randomization.  This analysis set will be used 
for the primary analyses of all safety endpoints.

Version 1.2 
6.3 
Interim Analysis Set 
There are 2 formal interim analyses planned for this study: 1 after both 280 PFS events and 
128 OS events have occurred and 1 after 256 OS events have occurred.  The interim analysis 
set will include all randomized patients who have at least 8 weeks of follow-up (ie, those 
who have reached the first scheduled response assessment) or who have discontinued the 
study prior to the first scheduled response assessment.  This analysis set will only be used in 
the analysis of objective response rate (ORR). 
6.4 
Subgroup Analyses 
The summaries of the primary and secondary efficacy variables and the comparisons of the 
treatment groups will be performed for subgroups defined by the covariates identified in 
Section 4.4. 
Summaries of treatment-emergent AEs will be provided for subgroups defined by age 
(< 65 vs ≥ 65), gender, and race (if feasible). 
7 
DATA SCREENING AND ACCEPTANCE 
7.1 
General Principles 
The case report tabulations (CRTs) will be built for this study.  Data will be reviewed and 
cleaned prior to the creation of the final CRTs for this study. 
7.2 
Handling of Missing and Incomplete Data 
Missing and incomplete data will be identified through a review of tables and listings for this 
study.  Missing and incomplete data will be identified for investigation, and possible 
resolution, by Allos Data Management prior to the study database lock. 
In general, missing data will be treated as missing, unless otherwise specified.  Missing and 
incomplete dates for AEs, concomitant medications, and historical data will be imputed 
within this study based on the conventions described in Section 11.3.  Any AE with no stop 
date will be considered ongoing. 
7.3 
Testing/Validation Plan 
SAS® Version 8.2 or higher on the Windows system will be used for all CRT and tables, 
listings, and graphs (TLGs) creation.12  Departmental standard macros will be used whenever 
appropriate for the creation of these items.  These macros, as well as SAS®, have already 
passed a rigorous validation process and further validation will not take place, although 
outputs will be verified.  The verification of all outputs, as well as the review of all programs 
and macros created specifically for this study, will be conducted as outlined in Allos 
Standard Operating Procedures.

STATISTICAL METHODS OF ANALYSIS 
8.1 
General Principles 
Unless otherwise indicated, analyses will be performed on the FAS. 
8.2 
Patient Accountability 
The number of patients randomized (FAS) and in the safety analysis set will be summarized 
by treatment group and stratum.  The reason for treatment discontinuation and study 
discontinuation will be summarized. 
The number of patients included in each analysis set will be presented. 
8.3 
Important Protocol Deviations  
The incidence of important protocol deviations (IPDs) will be summarized for each treatment 
group based on the IPDs identified within the database by the clinical study team.  These 
specific IPDs will be detailed in a separate document. 
8.4 
Demographic and Baseline Characteristics 
Demographics (age, gender, race, geriatric age group [< 65 years old vs ≥ 65 years old]) and 
other baseline disease characteristics including Eastern Cooperative Oncology Group 
(ECOG) performance status, IPI, and histopathology will be summarized using descriptive 
statistics for the FAS. 
8.5 
Efficacy Endpoints 
8.5.1 
Progression-free Survival 
The stratified log-rank test will be the primary method used to test the hypothesis that 
pralatrexate extends PFS relative to observation.  In addition, the stratified Cox regression 
model will be used to calculate the PFS HR, along with the 95% CI.  Strata used in these 
analyses will be those used for study randomization (as recorded using the interactive 
response technology [IRT]). Results of the unstratified Cox regression model (and log-rank 
test) will also be presented.  The proportional hazards assumption of the Cox model will be 
assessed.   
8.5.2 
Overall Survival 
The stratified log-rank test will be the primary method used to test the hypothesis that 
pralatrexate extends OS relative to observation.  In addition, the stratified Cox regression 
model will be used to calculate the OS HR, along with the 95% CI.  Strata used in these 
analyses will be those used for study randomization (as recorded using the IRT). Results of 
the unstratified Cox regression model (and log-rank test) will also be presented.  The 
proportional hazards assumption of the Cox model will be assessed.

Version 1.2 
It is recognized a priori that pralatrexate may be administered to Observation Arm patients 
subsequent to meeting treatment discontinuation criteria and thus, interpretability of the 
effect on OS may be confounded by crossover. 
8.5.3 
Objective Response Rate  
The number and percentage of patients with an objective response of CR or PR, relative to 
disease status at the time of study entry, will be summarized by treatment group.  The 
percentage will be calculated by dividing the number of patients within each category of 
response by the number of patients with measurable disease at baseline.  Each patient will be 
counted within only 1 response group, with the overall best response during the study as the 
classification group.  The treatment groups will be compared with respect to objective 
response rate (PR + CR) using the stratified Cochran-Mantel-Haenszel test.  A 2-sided 
95% exact CI will be calculated for the difference in objective response rates between the 
2 treatment groups.  Descriptive statistics will be provided for overall best tumor response for 
each treatment group. 
8.5.4 
Additional Analysis 
The relationship of the covariates listed in Section 4.4 to PFS time, OS time, and tumor 
response rate will be explored using a logistic regression model for tumor response rate and 
Cox proportional hazards regression models (univariate and multivariate) for the 
time-to-event endpoints. 
8.5.5 
Sensitivity Analyses 
A sensitivity analysis using the grouped survival methods of Prentice and Gloeckler may be 
performed on PFS time to assess the robustness of the results if there appears to be large 
differences in PD assessment patterns between the treatment groups.13 
If there is substantial crossover of observation patients to pralatrexate use, a sensitivity 
analysis for OS may be conducted censoring such patients at the date of first pralatrexate use.

Safety Analyses 
Analysis of safety will be performed on the safety analysis set.  Study data will be monitored 
on an ongoing basis by the clinical study team including the medical monitor and the clinical 
drug safety team’s routine activities to ensure patients’ safety. 
Adverse Events 
The Medical Dictionary for Regulatory Activities (MedDRA) will be used to code all AEs to 
a system organ class (SOC) and a preferred term.  Patient incidence of AEs will be tabulated 
by SOC, preferred term, and severity grade for all treatment-emergent AEs, serious adverse 
events (SAEs), treatment-related AEs, and treatment-related SAEs.  Each of these outputs 
will include tabulation by maximum severity for each SOC and preferred term as reported by 
the investigator based on Common Terminology Criteria for Adverse Events (CTCAE),

Version 4.0.  If an AE cannot be graded based on CTCAE, the investigator will assign a 
severity based on 1 = mild, 2 = moderate, 3 = severe, 4 = life threatening, and 5 = Death 
related to AE.  Summaries of AEs that are treatment-emergent, SAEs, treatment-related AEs, 
and treatment-related SAEs occurring in at least 5% of the patients will be provided in 
descending order of frequency by SOC and preferred term. 
Additional tables summarizing patient incidence (by preferred term) of the following will be 
generated: 
• 
All AEs; 
• 
SAEs; 
• 
Treatment-related AEs; 
• 
Treatment-related SAEs; 
• 
Grade 3 or higher AEs; 
• 
AEs leading to the discontinuation of pralatrexate or removal from study; 
• 
AEs leading to dose reductions of the study drug; 
• 
AEs with incidence ≥ 5%; and 
• 
Deaths. 
Adverse Events Grouped by Similar Preferred Term 
Summary tables of treatment emergent, treatment-related, serious, and serious 
treatment-related AEs grouped by similar preferred term will be presented.  For this 
presentation, certain similar preferred terms were identified and coded to the same preferred 
term in order to present the event in a uniform manner.  Terms are presented in Table 11.1 of 
Appendix 11.4 (additional preferred terms may be identified within each category during 
data review and added to this list).  
Separate outputs will be provided for subgroups defined by age group (< 65 and ≥ 65), 
gender, and race (if feasible). 
Detailed listings for all AEs and listings and/or narratives will be provided for serious and 
significant AEs and deaths (with “on-study” deaths [deaths that occur before the end of 
safety follow-up period] identified). 
Laboratory Parameters 
Laboratory parameters for hematology and blood chemistry will be summarized at baseline 
and last observed value.  Additionally, the maximum and minimum observed post-baseline 
values will be summarized along with the change from baseline to the maximum observed 
value, minimum observed value, and last observed value.  A listing of all laboratory 
assessments may be provided. 
Incidence of laboratory abnormalities and subject incidence of Grade 3 or 4 laboratory 
toxicities will be presented.  Summaries of hematology and serum chemistry parameters 
along with shifts in severity (CTCAE Version 4.0) from baseline for selected laboratory 
parameters will be presented.

PDX-017 Statistical Analysis Plan 
 
Version 1.2 
Plasma Pharmacokinetics 
Standard PK parameters will be estimated from the limited plasma sampling (eg, area under 
the curve [AUC], maximum concentration [Cmax], and half-life [t1/2]). 
Population PK (POPPK) analyses will be conducted via nonlinear mixed-effects modeling to 
estimate POPPK parameters for pralatrexate, including typical values, inter-individual 
variation, and residual variability after administration of pralatrexate in the patient 
population, and to estimate the effects of individual-specific covariate factors 
(eg, demographics, disease state, etc) that may be predictive of the unexplained random 
variability in pralatrexate PK.  In addition, the relationship between the PK of pralatrexate 
and response (safety and efficacy) will be explored. 
Eastern Cooperative Oncology Group Performance Status 
ECOG performance status scores will be summarized for each treatment group at each 
assessed time-point (ie, baseline and initial follow-up).  The change in scores from baseline 
to the initial follow-up visit will also be summarized.  A listing of ECOG scores will also be 
provided. 
Protocol-specified Treatment Administration 
For the Pralatrexate Arm, descriptive statistics will be calculated for total number of cycles 
started, the number of doses of each protocol-specified treatment, and the cumulative dose of 
each protocol-specified treatment.  A cycle will be considered “started” if a patient receives 
any protocol-specified treatment during that cycle.  The number and percentage of patients 
with modifications (including dose reductions, dose delays, or doses withheld) from the 
prescribed dosing of each of the protocol-specified treatments will be summarized by type of 
dose modification and reason for the dose modification.  The overall number of dose 
reductions/omissions/delays per patient will also be summarized. 
Electrocardiogram 
A listing of all observed electrocardiogram (ECG) results will be provided. 
Concomitant Medications 
The number and proportion of patients receiving each reported medication will be 
summarized by Anatomical Therapeutic Chemical (ATC) code and preferred term for each 
treatment group as coded by the World Health Organization Drug (WHODRUG) dictionary.  
A listing of all concomitant medications by patient will also be provided. 
B-symptoms and Pruritus 
Presence of B-symptoms (fever, night sweats, and weight loss), along with pruritus, will be 
captured at baseline and will also be collected post-randomization to determine if pralatrexate 
has an effect on these symptoms relative to observation.  Time to onset (worsening) of any,

11 APPENDICES 
11.1 Table/Figure/Listing Shells 
Table, listing, and figure shells will be provided in a separate document prior to final analysis 
of study data.   
11.2 Reference Values/Severity Grades 
Severity grades for AEs are provided by the investigator.  Severity grades for laboratory 
values will be derived programmatically based on the CTCAE grading scale – Version 4.0.  
For laboratory values requiring a clinical assessment for determination of severity, severity 
will not be derived programmatically. 
11.3 Handling of Dates, Incomplete Dates, and Missing Dates for 
Adverse Events and Concomitant Medications 
Imputation Rules for Partial or Missing Stop Dates 
If a partial or complete stop date is present and the “ongoing” or “continuing” box is 
checked, then it will be assumed that the AE or concomitant medication stopped and the stop 
date will be imputed if partial. 
Imputation Rules for Partial or Missing Start Dates for AEs and Concomitant Medications 
Several different date variables are kept in the standard analysis datasets for AEs and 
concomitant medications because the start and stop dates may be incomplete and data 
processing requires different assumptions about incomplete dates for different purposes.  
The standard AE analysis datasets have the following date variables: 
aestdc – character variable for AE start date.  It may be partial date (eg, 20MAY07, 
MAY07, 07) 
aestdt – numeric date variable for AE start date.  Missing for partial date. 
aefstdt – first possible AE start date.  For missing day of month, set to first day of month.  
For missing month, set to first day of year.  For missing year, set to missing value. 
aespdc – character variable for AE stop date.  May be partial date.  (See aestdc above.) 
aespdt – numeric date variable for AE stop date.  Missing if partial date. 
aelspdt – last possible AE stop date.  For missing day of month, set to last day of month.  For 
missing month, set to last day of year.  For missing year, set to missing value.

Aestrsp - first possible AE start date minus the treatment stop day.  Positive values are the 
number of days the AE started after treatment stopped and are used to set post-treatment 
cutoffs.  
Aestdc and aespdc are used for the main AE listings. Aefstdt and aelspdt are used for 
ordering records in chronological order. 
The standard concomitant medication analysis datasets have the following date variables: 
cmstdc – character variable for concomitant medication (CM) start date.  May be partial date 
(eg, 20MAY07, MAY07, 07) 
cmstdt – numeric date variable for CM start date.  Missing for partial date. 
cmfstdt – first possible CM start date.  For missing day of month, set to first day of month.  
For missing month, set to first day of year.  For missing year, set to missing value. 
cmlstdt – last possible CM start date.  For missing day of month, set to last day of month.  
For missing month, set to last day of year.  For missing year, set to missing value. 
cmspdc – character variable for CM stop date.  May be partial date.  (See cmstdc above.) 
cmspdt – numeric date variable for CM stop date.  Missing for partial date. 
cmfspdt – first possible CM stop date.  (See cmfstdt above.) 
cmlspdt – last possible CM stop date.  (See cmlstdt above.) 
cmstrsp – first possible CM start date minus the treatment stop day.  Positive values are the 
number of days the CM started after treatment stopped and are used to set post treatment 
cutoffs. 
Cmstdc and cmspdc are used for the main CM listings.  Cmfstdt and cmlspdt are used for 
ordering records in chronological order.
