Brief summary:
This phase II trial studies the best dose and how well liposomal cytarabine-daunorubicin CPX-351 (CPX-351) works in treating patients with newly diagnosed acute myeloid leukemia and who are at risk for not responding well to treatment. Liposomal cytarabine-daunorubicin CPX-351 combines two chemotherapy drugs that are known to help each other work better, and may work to stop the growth of cancer cells by blocking the cells from dividing.

Detailed description:
PRIMARY OBJECTIVE:

I. To assess preliminary efficacy (as determined by the rate of complete response \[CR\] or CR with incomplete blood count recovery \[CRi\]) of two or three dose levels of CPX-351 in patients with newly diagnosed acute myeloid leukemia (AML) at high risk for induction mortality, defined as 30-50% predicted risk of death by day 60, and to select the most promising dose level for further efficacy testing.

SECONDARY OBJECTIVE:

I. To confirm the rate of dose limiting toxicities, including induction mortality (at day 60) for two different sub-maximum tolerated dose (MTD) dose levels (50 and 75 U/m\^2).

EXPLORATORY OBJECTIVES:

I. To investigate the effect of CPX-351 on immune response, as determined by the effect on recovery of functional pathogen-specific and leukemia-specific immune responses and the recovery and function of natural killer (NK) cells.

II. To investigate the role of troponin-T as an early marker for CPX-351-induced cardiotoxicity.

III. To investigate ex vivo the cytotoxicity of combination of Pim-1 proto-oncogene, serine/threonine kinase (Pim) kinase inhibitor(s) and CPX-351 on circulating leukemia cells.

OUTLINE:

INDUCTION: Patients are randomized to 1 of 2 arms. After safety is established for both dose levels, and escalation is deemed feasible, an additional arm will be studied at the standard dose level.

ARM I: Patients receive lower-dose liposomal cytarabine-daunorubicin CPX-351 intravenously (IV) over 90 minutes on days 1, 3, and 5 of a 28-day course. Patients with persistent disease may receive a second course with treatment on days 1 and 3.

ARM II: Patients receive intermediate-dose liposomal cytarabine-daunorubicin CPX-351 IV over 90 minutes on days 1, 3, and 5. Patients with persistent disease may receive a second course with treatment on days 1 and 3.

ARM III: Patients receive standard-dose liposomal cytarabine-daunorubicin CPX-351 IV over 90 minutes on days 1, 3, and 5. Patients with persistent disease may receive a second course with treatment on days 1 and 3.

CONSOLIDATION THERAPY: Patients achieving CR receive liposomal cytarabine-daunorubicin CPX-351 on days 1 and 3. Treatment may repeat every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up monthly for as long as the study doctor thinks it is needed, every 2-3 months for up to 1 year, and every 3-4 months for up to 1 year.

Arms:
arm 1: Patients receive lower-dose liposomal cytarabine-daunorubicin CPX-351 IV over 90 minutes on days 1, 3, and 5 of a 28-day course. Patients with persistent disease may receive a second course with treatment on days 1 and 3. arm 2: Patients receive intermediate-dose liposomal cytarabine-daunorubicin CPX-351 IV over 90 minutes on days 1, 3, and 5. Patients with persistent disease may receive a second course with treatment on days 1 and 3. arm 3: Patients receive standard-dose liposomal cytarabine-daunorubicin CPX-351 IV over 90 minutes on days 1, 3, and 5. Patients with persistent disease may receive a second course with treatment on days 1 and 3.

1.0 General Information 
This document is a protocol for a human research study. This study is to be conducted 
according to United States and international standards of Good Clinical Practice (FDA 
Title 21 parts 11, 50, 54, 56, 312, International Conference on Harmonization and the 
Declaration of Helsinki), applicable government regulations and Institutional research 
policies and procedures. 
2.0 Background Information 
2.1 
Acute Myeloid Leukemia in the Elderly and its Treatment 
Acute myeloid leukemia represents a group of clonal hematopoietic stem cell disorders in 
which both failure to differentiate and excessive proliferation in the stem cell 
compartment result in accumulation of non-functional cells termed myeloblasts.(1) 
 
Untreated AML in all ages is rapidly fatal, with patients dying on average within a few 
months of diagnosis.  Even with treatment, particular groups of AML patients continue to 
have a poor prognosis.  AML in the elderly (age ≥60) is associated with increased risk of 
not responding to therapy and increased risk of dying from the treatment.  Appelbaum, et 
al.(2) and Kantarjian, et al.(3) summarize the factors that contribute to poor outcomes in 
elderly patients with AML. Risk factors that decrease patient tolerance to therapy or 
sensitivity of the leukemia to therapy include increasing age, poor performance status, co-
morbid medical conditions, accumulated chromosomal abnormalities, adverse mutations, 
and multi-drug resistance. 
 
There is broad overlap of these risk factors with most elderly AML patients having one or 
more adverse features.  The poor results of treatment in elderly AML lead to a reluctance 
to treat elderly patients with intensive regimens designed to induce aplasia and complete 
remission. 
 
Clearing the marrow of leukemia has historically been the only means of obtaining 
prolonged survival in AML patients.  This is usually accomplished by use of intensive 
cytotoxic/cytoreductive therapy.(4)  The intensity of treatment needed to induce aplasia 
and complete remission is associated with early mortality rates of 10-20% in elderly 
patients considered fit for intensive therapy and is higher in patients with risk factors 
indicating less sensitive leukemia, co-morbidities, and poor performance status.(2, 3, 5-7) 
 
A randomized study reported in 2009 showed that a double induction regimen with 90 
mg/m2 daunorubicin with cytarabine (first induction) followed by a second induction 
with intermediate dose cytarabine (1 g/m2) could be safely administered with high rates 
of complete remission in older patients. The second induction was given even to patients 
already morphologically leukemia-free after first induction, a practice that is not routinely 
used in the U. S. and Canada.  This publication from the HOVON group noted 
improvement in remission rate when compared to a traditional regimen of cytarabine plus 
daunorubicin (45 mg/m2) but no improvement in disease-free survival or overall survival

was noted.(8)  At the present time, the HOVON study has not been replicated in elderly 
patients by any other group.  
 
Another study by Fernandez, et al., reported success for the same higher dose 
daunorubicin regimen (90 mg/m2) versus 45 mg/m2 of daunorubicin when used for first 
induction for younger patients.(9) For second inductions, the dose of daunorubicin was 
reduced to 45 mg/m2 for all patients.  Responding patients were taken to transplant.  
Neither this study nor the HOVON study used daunorubicin 90 mg/m2 for second 
induction courses or in consolidation and neither study demonstrated that 90 mg/m2 is 
more effective than 60 mg/m2.  Although of great interest, neither regimen is ready to be 
used as the control arm in a comparative study with CPX-351. 
 
For patients at high risk of relapse (e.g. those with high-risk cytogenetics, underlying 
MDS, or therapy-related AML), allogeneic stem cell transplantation is usually 
recommended if the patient is able to tolerate a transplant and has a suitable donor. 
 
For patients with older age or co-morbidities the risk of induction treatment remains high.  
Patients age 65 or older treated with standard 3+7-like chemotherapy have been reported 
to have an induction mortality rate of 20%.(8, 10) Those with adverse cytogenetic 
abnormalities have a significantly higher risk of early mortality.(8, 11) At MD Anderson, 
patients at relatively high (30-50%) risk for induction mortality (60-day) can be 
identified.  Patients in this age group with adverse cytogenetic abnormalities have an 
early mortality rate of 35% compared to 22% for those in the same age group with 
diploid cytogenetics (Tambaro et al. ASH 2012). In addition, an analysis of 998 patients 
age 65 or older with AML or high-risk MDS analyzed the factors associated with 
increased risk for early mortality and, consequently, poor long-term outcome. By 
multivariate analysis, age 75 years or older, performance status ≥2, complex karyotype, 
treatment outside a laminar air-flow setting, antecedent hematologic disorder of at least 
12 months duration prior to the diagnosis of AML, and a creatinine >1.3 mg/dL were 
identified as independent factors associated with increased risk of mortality by 8-weeks 
from the start of induction chemotherapy.(3) Patients with none of these risk factors have 
an 8-week mortality probability of 10%, with a median survival of 16 months and 1-year 
projected survival of 58% and are considered a low-risk group. In contrast, for those with 
1 or 2 risk factors (i.e., the intermediate risk group) the 8-week mortality rate is 19-36% 
with median survival of 4-9 months and 1-year survival rates of 22-35%. Those with 3 or 
more risk factors (the high-risk group) have a 65% probability of early mortality, median 
survival of 1 month and 1 year projected survival of 8%.(3) For patients with intermediate 
or high risk the decision to treat with intensive chemotherapy is difficult because the 
benefits have been approximately equal to the risks.  Studies using non-intensive 
treatment have been performed indicating reduced early risk with reduced benefit.  The 
need for effective treatment with acceptable treatment safety remains urgent.   
 
2.2 
CombiPlex Technology 
In vitro studies have shown that antitumor activity can be enhanced when cytotoxic drugs 
are used in combination.  This has led to cytotoxic drug combinations as standard therapy

FINAL 
in many forms of cancer treatment.  New anticancer drugs are typically first introduced in 
patients as single agents.  After a maximum tolerated dose is determined for one agent, a 
second agent is added and the dose of one or both agents is adjusted on the basis of 
toxicity.  The development of these combination regimens then is determined empirically 
on the basis of tolerability.  However, in vitro, where the molar ratio of drugs used in 
combination can be controlled, it has been demonstrated that drug combinations 
providing synergy at one ratio may be simply additive or even antagonistic at other 
ratios.(12)  When individual free drugs are administered, each agent is handled 
differently by the body, resulting in differences in the distribution and elimination of the 
individual drugs to tumor sites which must result in drug ratios that are sometimes 
suboptimal or ineffective.  The manufacturer’s technology is based on findings that in 
vitro synergistic activity of antineoplastic drugs depends on specific drug ratios and that 
the in vivo activity of a combination depends on maintaining the synergistic ratio.  In this 
way, the development of a particular chemotherapeutic regimen can be based on the most 
efficacious ratio rather than empirically based on toxicity. 
 
The development of CPX-351 (cytarabine:daunorubicin) Liposome Injection was based 
on 1) defining a synergistic ratio of the two active moieties, cytarabine and daunorubicin, 
using cell-based screening assays and 2) designing a liposomal drug carrier to maintain 
this ratio after intravenous administration.  This ratio was not based on the empirically-
derived, toxicity-guided regimens currently used for cytarabine and anthracyclines. 
 
2.3 
Physical, Chemical and Pharmaceutical Information 
CPX-351 is a liposomal formulation of a fixed combination of the antineoplastic drugs 
cytarabine and daunorubicin. The two drugs are present inside the liposome in a 5:1 
molar ratio.  The liposome membrane is composed of distearoylphosphatidylcholine, 
distearoylphosphatidylglycerol and cholesterol in a 7:2:1 molar ratio.  These liposomes 
have a nominal diameter of approximately 100nm and are suspended in sucrose.  
Sterilization is achieved by filtration through a 0.22 µm filter. 
 
CPX-351 is provided as a sterile, pyrogen-free lyophilized formulation in 50 ml glass, 
single-use vials.  Each vial contains 100 units of CPX-351 where each unit contains 1.0 
mg cytarabine and 0.44 mg daunorubicin base in liposomes.  The lyophilized cake is 
reconstituted with water for injection to obtain a homogeneous dispersion at 5 units/mL.  
The composition of the formulation after reconstitution is listed in Table 1 below.

The primary goal for this study was to establish the MTD for CPX-351 and recommend a 
dose for further study in a Phase II setting.  Pharmacokinetics was assessed at every dose 
level and patients were monitored for signs of antileukemic activity. 
 
The dosage regimen was designed to mimic the 7-day drug exposure provided by 
conventional 7+3 treatment.   A single induction course administers doses on Days 1, 3, 
and 5, by 90 minute infusion.  Patients with AML (multiply relapsed, refractory, or with 
first CR duration of 6 months or less), ALL, and high risk MDS were eligible. 
 
Dose limiting toxicities were observed at the 10th dose level: 134 u/m2 (134 mg/m2 
cytarabine + 59 mg/m2 daunorubicin).  One patient had significant reduction in post 
treatment LVEF and as a result both Phase II studies included a cap (500 mg/m2) on 
cumulative anthracycline dose after one induction course of CPX-351 and patients with 
significant pre-existing cardiac disease were excluded.  Other dose-limiting toxicities 
included hypertensive crisis and prolonged (>56 days) cytopenias. 
 
The Phase I study of CPX-351 assessed the concentrations of cytarabine, daunorubicin, 
uracil arabinoside, and daunorubicinol at multiple dose levels and found that they 
exhibited mono-exponential, first order elimination with minimal early phase 
distribution.  (Figure 1)

The day 1 (single dose) and day 5 (multiple dose) Cmax and AUC(0-) were linear and the 
5:1 molar ratio of cytarabine to daunorubicin was maintained for up to 24 hours at all 
dose levels on days 1 and 5.

FINAL 
The pharmacokinetic analysis confirmed higher absolute plasma concentrations of both 
drugs compared to that expected with the conventional 7+3 regimen with a markedly 
prolonged mean half-life for both cytarabine and daunorubicin and greater drug exposure 
(AUC).  Measurable drug levels were present seven days after the last infusion of CPX-
351 (Study Day 12).  Compared to infusions of the conventional drugs, CPX-351 
administration was associated with substantially greater AUC and half-lives for plasma 
cytarabine and daunorubicin.(13)  (Table 2)

Three of the 48 patients entering the study had ALL and a transient CR was achieved in 
one patient at the 43 unit/m2 dose level.  Two patients with high risk MDS were treated at 
lower dose levels and neither responded. The remaining 43 patients had AML; 20 
patients after multiple relapses or multiple treatment regimens, 18 after relapse from a 
first CR, and 5 after primary induction failure.  Complete response was observed in 10 of 
43 AML patients, a notable observation because most patients had received cytarabine 
and daunorubicin in the past and because of the low frequency of non-hematological 
toxicities observed with CPX-351. 
 
In conclusion, the Phase I study defined the maximally tolerated dose (101 u/m2) for a 
day 1, 3 and 5 induction course of treatment and confirmed persistence of the 5:1 molar 
ratio for up to 24 hours in the plasma with markedly prolonged median half-life for both 
cytarabine and daunorubicin.  Multiple responses in previously treated AML patients 
provided proof of antileukemic activity. 
2.6.2 Phase II Study of CPX-351: CLTR0308-204 
The 204 study was designed as a randomized study comparing CPX-351 head-to-head 
against 7+3, in newly diagnosed, older (age 60-75) patients with AML.  The comparison 
of encapsulated cytarabine and daunorubicin (CPX-351) versus free cytarabine and 
daunorubicin (7+3) would be fully interpretable for relative efficacy and safety and 
would begin to provide evidence supporting or refuting the hypothesis that dosing based 
on molar ratios would lead to improved efficacy.

One hundred twenty-seven patients were randomized from 18 of 28 study sites. The study 
was amended to extend follow-up to 2 years when it became apparent that 1 year follow-
up would be insufficient to capture median survival in both study groups. 
 
A two to one randomization was used to maximize experience using CPX-351.  Response 
rate (CR+CRi) was the primary endpoint and superior response with a one-sided p-value 
of <0.1 was deemed sufficient for moving forward in development. Secondary endpoints 
were overall survival, event-free survival, CR+CRi duration, rate of aplasia, safety and 
practicality of CPX-351 as consolidation therapy and the response rate of CPX-351 
between de novo and secondary AML. 
 
 
 
At entry patients were stratified by age (60-69 vs. 70-75), cytogenetics (< or ≥3 
cytogenetic abnormalities), and type of AML (de novo vs. secondary).  High risk patients 
were older (age 70-75) or had complex cytogenetics (≥3 cytogenetic abnormalities) or 
had secondary AML.  Standard risk patients were younger (age 60-69), had non-complex 
cytogenetics (<3 abnormalities) and had de novo AML.  After accrual was complete, Dr. 
Jeffrey Lancet (H.L. Moffitt Cancer Center, Tampa, FL) reviewed all of the cytogenetic 
reports and confirmed/corrected assignment of patients to <3 or ≥3 cytogenetic 
abnormalities.  In addition he also assigned each patient to a specific cytogenetic risk 
group (adverse vs. intermediate vs. unknown) according to National Comprehensive 
Cancer Network guidelines 
(NCCN:www.nccn.org/professionals/physician_gls/PDF/aml.pdf).  Dr. Lancet’s 
assessment of cytogenetic risk is shown in Table 3. 
 
Table 3 demonstrates balanced assignment of patients to both arms of the study 
indicating successful randomization and stratification.

Table 4 demonstrates that CPX-351 produced superior rates of aplasia/hypoplasia and 
response with similar duration of remission.  It was notable that the improvement in 
response occurred in the form of CRi (CR with incomplete hematologic recovery).

FINAL 
Kaplan-Meier (K-M) analysis after a minimum follow up of 1-year for Event Free 
Survival (EFS, based on documentation of persistent leukemia, relapse after CR, or 
death) and Overall Survival (OS) demonstrated non-significant improvements for CPX-
351 in the overall study population and the high risk population.  K-M analysis of the 
secondary AML population (including treatment-related AML and AML occurring in the 
setting of antecedent hematologic disorders, e.g. myelodysplasia, myeloproliferative 
disease, and chronic myelomonocytic leukemia) showed a significant improvement in 
overall survival (p-value=0.01) with a median survival improvement of 6 months (12.1 
vs. 6.1 months).  The overall survival and event-free survival curves shown in Figure 2 
through Figure 4 include crossover patients in the Control Arm based on their original 
treatment assignment.  This confounds the interpretation of OS, but as the patients are 
considered as having an event at crossover, this confounding is not present in the EFS 
curves.  Given the number of EFS events, the EFS curves are relatively mature.  The OS 
curves, with only about 50% of the events, are less mature.

Induction mortality was assessed at Day 30 and 60.  A lower rate of early mortality was 
observed for CPX-351 treated patients (See Table 6).  This result is the best evidence that 
CPX-351 treatment is safe and suggests that rapid clearance of leukemia may assist in 
reducing the early death rate.

Adverse events were qualitatively similar between both study arms.  Adverse events with 
increased frequency in the CPX-351 arm were linked to greater myelosuppression with 
higher rates of febrile neutropenia (63.5% vs. 51.2%), bacteremia (42.4% vs. 22%), 
epistaxis (36.5% vs. 19.5%), and petechiae (32.9% vs. 12.2%).  This appears to be due to 
more prolonged myelosuppression (median ANC recovery to ≥1000/L: 36 vs. 29 days 
and median platelet recovery to ≥100,000/L: 37 vs. 27 days).  Serious fungal infections 
were more frequent on CPX-351 versus 7+3.  These tended to occur during the period of 
nadir neutropenia and resolved at recovery. There were no grade 5 fungal events.  A 
variety of non-hematologic adverse events appear to be more frequent after CPX-351, but 
most, including cough, rash, and headache were usually of grade 1-2 severity and were 
transient.  The key safety findings were that CPX-351 had lower than expected 60-day 
mortality (4.7% vs. 14.6%), lower rates of adverse events with grade 5 outcome (11.8 vs. 
17.1),  and more prolonged myelosuppression with higher rates of febrile neutropenia, 
infections and bleeding events but no increase in deaths associated with infection when 
compared to 7+3.  Non-myelosuppressive adverse events were similar in quality in both 
study arms and there was no evidence of excess cardiac events, in this group of 
anthracycline-naïve patients.

FINAL 
The 7+3 control arm performed as expected, based on the literature, with moderate 
induction mortality (60 day death rate=14.6%) and a 51.2% CR+CRi rate.  However, a 
projected median overall survival of slightly greater than 12 months (12.9 months) was 
slightly better than expected. 
 
A search for imbalances that could have biased study results in favor of CPX-351 was 
performed and no imbalance in post-induction bone marrow transplants, no major 
imbalance in the characteristics of secondary AML patients (including type of antecedent 
hematologic disorder), and no imbalance in prior treatment with hypomethylating agents 
was found.  Fewer patients on the 7+3 arm received subsequent therapy after persistent or 
relapsed disease, but most of this imbalance was due to the high rate of early mortality 
among control arm patients, preventing subsequent therapies from being given to control 
arm patients.  
 
2.6.3 Phase II Study of CPX-351: CLTR0308-205 
This study compared CPX-351 (100u/m2; Day 1, 3, 5) with salvage therapy in first 
relapse AML patients.  This trial planned to accrue 120 patients with a 2:1 randomization.  
Investigator choice of control salvage regimen was expected to be between (1) high dose 
cytarabine with or without daunorubicin, (2) 7+3 or (3) mitoxantrone, etoposide and 
cytarabine.  The allowance of investigator’s choice reflects the fact that no single salvage 
therapy is superior and the necessity of individualizing treatment.  Responding patients 
were expected to receive allogeneic stem cell transplant for consolidation if donors were 
available. 
 
The European Prognostic Index was used to stratify patients.  For this trial, the primary 
endpoint was survival at one year, which for the control arm was expected to be 30% 
based on previous clinical trials and the literature.  Secondary endpoints were CR+CRi 
rate, remission duration, event-free survival and 30/60/90 day mortality.  The 1 year 
survival rate was selected as the primary endpoint rather than response rate because of the 
substantial variability of the CR rate for different salvage regimens reported in the 
literature.  Accrual was completed in November 2010 with 81 patients randomized to 
CPX-351 and 45 randomized to salvage therapy. 
 
Patient demographics were well balanced between the two arms for durations of first 
complete remission, cytogenetics, and age.  There was a slight imbalance in history of 
prior stem cell transplants with more patients in the CPX-351 arm having a history of 
transplant.  Study stratification was successful with approximately 2/3’s of patients in 
both study arms in the unfavorable EPI risk group.

The EFS and OS results did not demonstrate statistically significant improvements for the 
group as a whole, but significance was found for survival in the subset of relapsed 
patients with EPI Unfavorable disease.  These results echo those found for the secondary 
AML population in Study 204, in that significant differences in patient outcomes were 
observed in patients with less sensitive AML because of a substantial fall off in efficacy 
for the control arm.

FINAL 
A search for imbalances that could have biased study results in favor of CPX-351 was 
also performed and imbalances in post-induction bone marrow transplants were not 
found.  The rate of post-induction HSCT was similar between the two study arms among 
patients with CR, CRi, and persistent AML, suggesting that transplants did not bias the 
study. 
 
Safety data were consistent with those from Study 204.  Patients with no history of prior 
stem cell transplant at study entry were in the majority (96/125, 76.8%) and were found 
to have slightly lower 60-day mortality (10.2% vs. 16.2%) and higher complete response 
rates (54.2% vs. 37.8%).   Patients with prior stem cell transplants had poorer results after 
CPX-351 with somewhat higher 60-day mortality (27.3% vs. 14.3%) and lower response 
rate (35.4% vs. 57.1%).  The prior stem cell transplant group was too small to reach 
definitive conclusions but it is possible that patient groups with extensive prior 
chemotherapy may be at higher risk following CPX-351 treatment. 
 
Overall, Study 205 confirmed and extended observations first made in Study 204.  CPX-
351 is highly active with improved clearance of leukemia and higher response rate, even 
in patients with prior exposure to cytarabine and anthracycline.   CPX-351 was also 
shown to be safe with improved 60-day mortality in the majority of patients with no prior 
history of HSCT.  These results suggest that CPX-351 will be an excellent candidate to 
test in newly diagnosed AML patients with high risk of treatment mortality. 
 
2.7 
Copper Background 
Copper is an essential element that is a component of a number of metalloenzymes acting 
as oxidases (e.g. diamine oxidase, monoamine oxidase, cytochrome c oxidase).  The 
median absorption of copper from food (by an American adult) is 1.0 to 1.6 mg/day.  The 
tolerable Upper Intake Level for adults is 10 mg/day.  At a dose of CPX-351 of 100 u/m2, 
a patient with a BSA of 2.0 m2 would receive a maximum of 36 mg of elemental copper 
per dose.  In the animal toxicology investigations for CPX-351, elevated copper levels 
were seen following dosing with levels generally returning to baseline 1 to 2 weeks after 
the last dose (see Figure 5).  No toxicity seen in animal studies was attributable to copper. 
 
The data from the clinical studies are consistent with the preclinical findings.  Since 
CPX-351 contains copper (0.18 mg copper per unit, in the form of copper gluconate), 
serum total copper levels were monitored in the Phase 1 clinical study (Study 
CLTR0305-101).  Figure 5 shows this data for cohort 9 (n=20, dose 101 units/m2) 
graphically:

FINAL 
Figure 5:  Median and Mean Serum Copper in Cohort 9 after the First Induction 
 
 
 
As Figure 5 shows, both the median and mean copper levels in patients receiving 3 doses 
of CPX-351 at 101 units/m2 was very high on day 7 (2 days after the last dose) but 
returned to normal levels in most patients by day 14.  All patients had serum copper 
levels in the normal range by day 42 after the first induction.  In summary, no safety 
problems are expected due to systemic copper exposure from CPX-351. 
 
In this trial, serum copper levels will be monitored and elevated levels are assumed to be 
due to copper gluconate encapsulated within the CPX-351 liposome rather than free 
circulating copper.  Clinical observation from a single patient treated with the identical 
copper-containing liposome encapsulating a different chemotherapy doublet (CPX-1, 
floxuridine and irinotecan) demonstrated sustained elevations of copper in a patient 
during a period of biliary obstruction, with return to baseline levels after stenting relieved 
the obstruction.  This anecdote suggests that copper elimination after CPX-351 is likely 
via biliary excretion and elimination in the feces.  Preclinical studies completed by 
Celator (acquired by Jazz Pharmaceuticals) demonstrated that virtually all of the copper 
administered in the form of CPX-351 is excreted via the feces within approximately 2 
weeks of administration.  It is expected that eligible patients with unobstructed biliary 
systems should be able to eliminate the copper administered within a few weeks.  Serum 
copper levels will be monitored until they return to baseline levels (±20%) and patients 
will be monitored for hepatic dysfunction, a common manifestation of copper-related 
toxicity.

FINAL 
3.0 Study Objectives and Rationale 
3.1 
Primary Objectives 
The primary objective of this study is to assess preliminary efficacy (as determined by the 
rate of CR or CRi) of two or three dose levels of CPX-351 in patients with newly 
diagnosed AML at high risk for induction mortality, defined as 30-50% predicted risk of 
death by Day 60, and to select the most promising dose level for further efficacy testing.  
Estimation of risk for induction mortality at patient screening will be based on factors 
associated with lower likelihood of AML response with or without factors that reduce 
tolerance to treatment-associated adverse events.   
 
3.2 
Secondary Objectives 
To confirm the rate of dose limiting toxicities, including induction mortality (at day 60) 
for two different sub-MTD dose levels (50 and 75 U/m2).  If safety results suggest 
feasibility to test the MTD dose level of CPX-351 (100 U/m2) in patients believed to be at 
high risk for induction mortality, the rate of dose limiting toxicities and induction 
mortality will be tested in this group as well.  
 
 
3.3 
Exploratory Objectives 
To investigate the effect of CPX-351 on immune response, as determined by the effect on  
recovery of functional pathogen-specific and leukemia-specific immune responses and 
the recovery and function of NK cells. 
To investigate the role of Troponin-T as an early marker for CPX-351-induced 
cardiotoxicity.  
To investigate ex vivo the cytotoxicity of combination of Pim kinase inhibitor(s) and 
CPX-351 on circulating leukemia cells. 
 
3.4 
Study Rationale 
The Phase I study identified the MTD in fit relapsed and refractory adult leukemia 
patients and confirmed that the intended 5:1 molar ratio was maintained for 
cytarabine:daunorubicin across multiple dose levels with markedly prolonged plasma half 
life of cytarabine and daunorubicin.  At the MTD, CPX-351 was detectable in plasma at 
least 7 days after the last dose (Study Day 12).  A substantial number of responses were 
observed among late stage patients already previously treated with cytarabine and 
daunorubicin.   
 
The randomized Phase II results with CPX-351 suggest that CPX-351 is likely better 
tolerated than conventional cytarabine and daunorubicin-based chemotherapy with 
reduced 60-day mortality (4.6%) observed among newly diagnosed patients.  Moreover, 
preclinical observations that CPX-351 concentrates in bone marrow with evidence for 
relatively selective internalization of liposomes within the cytoplasm of leukemia cells

FINAL 
suggests that CPX-351 action will be potent and that non-hematopoietic toxicities will be 
modest.  Clinical observations from the Phase I study of complete response occurring at 
dose levels as low as one third to one half the MTD (32 to 43 units/m2), strongly suggest 
that 25% and 50% dose reductions to 75 and 50 units/m2 will still be effective and should 
be better tolerated.  By using reduced dose CPX-351 as induction therapy it may be 
possible to improve the outcome of patients with AML considered at high risk for 60-day 
mortality, patients not ordinarily offered induction therapy for AML at all.   
 
Data from the Phase I and both Phase II studies also demonstrated a relatively shallow 
dose/toxicity curve, with relatively little increase in non-hematopoietic toxicities with 
increasing doses up to the MTD.  If sub-MTD dose levels of CPX-351 are well tolerated 
in patients at higher risk of early mortality, it may be possible to evaluate treatment at the 
MTD for patients at high risk for induction mortality.   To the extent that higher dose 
levels maximize treatment efficacy, demonstration of treatment safety and feasibility at 
the MTD may permit treatment with the most efficacious dose level in patients at high 
risk for induction mortality.  
 
4.0 Study Design 
One cycle equals 28 days. 
 
This study is an open-label, two-arm or possibly 3-arm, phase II trial.   CPX-351 is 
administered as approximately a 90-minute infusion on days 1, 3, and 5 with one study 
arm receiving 50 units/m2 and the other receiving 75 units/m2.   Both the 50 and the 75 
unit/m2 dose levels are considered to have acceptable safety based on observations from a 
pair of randomized Phase II studies conducted in adult patients, where the observed 60-
day mortality results in patients considered fit for intensive chemotherapy and with no 
prior history of stem cell transplant, was observed to be reduced compared to control.   
 
Patients with newly diagnosed AML who are predicted to be at high risk (30-50%) for 
induction mortality (death by day 60) are eligible.  Every patient entered must have at 
least one AML-related factor (adverse cytogenetics, secondary AML, MDR phenotype, 
etc.) that contributes to elevated risk of induction mortality.   Patients may or may not 
have patient-related factors (poor performance status, co-morbidities, poor organ 
function, etc.) that also contribute to elevated risk of induction mortality. 30 patients will 
be randomized with a 1:1 ratio to the two dose arms with 15 patients per arm to assess for 
safety and efficacy.  If safety is demonstrated for both of the sub-MTD dose levels, and 
escalation is deemed feasible above 75 units/m2, a cohort of 15 patients will be studied at 
100 units/m2, the MTD dose level. The latter dose (i.e., 100 units/m2) was found safe and 
an additional 25 patients will be enrolled at this dose (for a total of 40 evaluable patients) 
to define efficacy at this standard dose. 
 
At the end of the study a single dose level will be confirmed to have acceptable safety if 
the observed rate of dose limiting toxicity (DLT) is <5 DLT/15 patients.<33%).  Dose 
limiting toxicity is defined as induction mortality (death occurring during the first 60 
days from start of study therapy), grade 3 or 4 non-hematologic toxicity, or dose limiting

FINAL 
hematologic toxicity at least possibly related to the study drug occurring during the first 
60 days from the start of study therapy (i.e., during the first cycle of therapy).   
 
For non-hematologic toxicity the following are counted as dose limiting toxicities only 
under the conditions noted: 
 Liver toxicity: Grade 4, related to the study drug, not resolving to grade 2 within 7 
days.  
 Decrease in ejection fraction: Grade ≥3 (nadir LVEF <40-20%), related to study 
drug 
 Creatinine elevation:  Grade ≥3, related to study drug. 
 Any other adverse event of Grade ≥3, related to study drug that in the opinion of 
the PI is inconsistent with the expected adverse events with standard 
chemotherapy.  
 
Dose limiting hematologic toxicity is defined by bone marrow and peripheral blood 
examination at Day >56 showing: 
 Absence of recurrent or persistent leukemia AND 
 Persistently hypocellular marrow (<20% cellularity) AND 
 Peripheral blood: 
o ANC< 500 and/or 
o Platelet count <10,000 
 
If more than one dose level is considered acceptably  safe, the decision about which one 
to use for future clinical study will be based on efficacy.  Efficacy success for an 
individual patient is defined as achievement of CR or CRi.  Observation of <3 CR or CRi 
among 15 patients (<20%) defines a non-efficacious study arm.  In situations where both 
study arms are considered equally safe, the study arm with the higher rate of response 
will be recommended for future study, provided it equals or exceeds 20%.   
When the dose recommended for future study is defined, 10 additional newly diagnosed 
patients will be treated at that dose level (not to exceed a total of 25 patients at that dose 
level) to obtain additional evidence of safety and efficacy among previously untreated 
patients with high risk of induction mortality.   
 
4.1 
Patient Recruitment 
All patients will be screened by a principal investigator or sub-investigator prior to entry 
on the study.  An explanation of the study and discussion of the expected risks and 
benefits will be fully discussed with patients prior to the screening process in order for 
the patient to provide a voluntary written informed consent.  Only eligible and consenting 
patients will be entered into the study. 
 
4.2 
Registration Procedures 
Patients will be registered through CORe.

4.3 
Patient Sample Size 
A maximum of 80 patients will be treated. 
 
A minimum of 15 patients will be treated at each dose level, unless conditions for early 
stopping are met based on excessive toxicity or insufficient safety (see section 10.0).  
 
4.4 
Toxicity Assessment 
Toxicities will be evaluated and graded according to the NCI Common Terminology 
Criteria for Adverse Events, version 4 (CTCAE). 
 
If a patient is discontinued due to progressive disease or intercurrent illness unrelated to 
toxicity attributable to CPX-351 and before safety can be assessed to rule out DLT, an 
additional patient will be recruited, to ensure that the minimum number of patients are 
evaluable for safety at each dose level. 
4.5 
Second Inductions 
A second induction may be given if: 
 
The first induction does not produce a day 28 bone marrow demonstrating 
morphologic leukemia free state (≤5% blasts)  
 
Second inductions are given at the discretion of the investigator but are 
recommended in any patient with documentation of reduced leukemic burden, 
especially those with evidence of partial remission (≥50% reduction in % blasts 
count to 5-25% blasts).  
 
Second induction may be started on Day 28 from 1st cycle.  In patients with 
rapidly proliferating disease second induction may be started earlier (but not 
earlier than Day 21) provided there is no residual study drug-related grade 2 non-
hematologic toxicity after discussion with the principal investigator. 
 
The CPX-351 dose for second induction is the same as for initial induction except that 
doses are given on Days 1 and 3 only.  Patients unable to achieve a response (CR+CRi) 
after two inductions are discontinued from further treatment and are followed for survival 
only. 
 
4.6 
Consolidation Therapy 
Only patients with documented response (CR or CRi) are eligible for consolidation.  
Consolidation with stem cell transplant (HSCT) is permitted either in place of 
chemotherapy consolidation or after chemotherapy consolidation.  Prior to beginning 
every other chemotherapy consolidation after the cumulative DNR dose exceeds 300 
mg/m2,or  prior to every course of treatment after the cumulative DNR dose exceeds 500 
mg/m2, patient LVEF must be documented to be ≥50% and patient PS must be 0-2.   
 
Patients in CR with full recovery of peripheral blood counts within 56 days may be 
consolidated starting within one week of documentation of response.  Patients with CRi 
may start consolidation no earlier than 42 days after the start of the last induction course

and only if ANC is >500/L and Platelets are >50,000/L.  Consolidation courses consist 
of 2 doses administered at 65 units/m2 on days 1 and 3.    
A maximum of 4 courses of consolidation will be administered. It is understood that 
variations in timing of second induction and consolidations may be necessary and will be 
decided on a case by case basis by the PI. The rationale for variations in schedule will be 
documented by the PI.  If consolidation is well tolerated and hematopoietic recovery is 
not delayed beyond 56 days, additional courses of consolidation may be offered 
immediately at time of recovery.  In cases of poor patient tolerance or delayed 
hematopoietic recovery, the principal investigator will document his decision to either 
continue or terminate consolidation treatment.

Evaluation during Treatment 
Inductions and consolidations are administered as courses.  A course consists of the 
administration of therapy with scheduled assessments to evaluate the response to 
treatment.  The first induction may end before the completion of all evaluations if a 
second induction is necessary, (see Section 4.5).  Induction is completed when a patient 
has 
 
A confirmed CR (see section 8.4) 
 
A CRi (see section 8.4) and is to begin consolidation treatment before 
documentation of hematologic count recovery 
 
Persistent/recurrent disease (PD/relapse) 
 
Response evaluation cannot be performed because of the patient’s condition and 
no further study treatment can or will be administered. 
 
Patients with a CR or CRi may receive consolidation treatments.  Evaluations on Days 1-
10 must be performed on the day indicated (±2 day); all other evaluations are to be 
performed on the Study Day indicated ±3 days, except when specifically indicated.  Each 
course requires the following evaluations:

Page 33 of 61 
FINAL 
The responsibility for treatment of patients rests with the individual investigator.   
 
7.1 
Drug Preparation and Administration 
7.1.1 Drug Preparation 
The appropriate number of vials of CPX-351 (cytarabine:daunorubicin) Liposome 
Injection should be removed from the refrigerator prior to reconstitution.  Reconstitute 
with 19 mL of water for injection using a 20 mL syringe. Do not heat CPX-351 
(cytarabine:daunorubicin) Liposome Injection.  After reconstitution, invert vials gently 3-
4 times and let rest for 15 minutes prior to withdrawing drug for dilution.  CPX-351 
(cytarabine:daunorubicin) Liposome Injection should be diluted in approximately 500 
mL of saline injection or dextrose injection. 
 
The IV bags and infusion sets must be non-DEHP.  Aseptic technique must be strictly 
observed throughout the handling of CPX-351 (cytarabine:daunorubicin) Liposome 
Injection, since no bacteriostatic agent or preservative is present.  The infusion of CPX-
351 (cytarabine:daunorubicin) Liposome Injection must be started within 4 hours of 
dilution.  Vials are for single use.  Unused material should be recorded as such and 
discarded according to institutional policies.  Procedures for proper handling and disposal 
of anticancer drugs should be implemented. 
 
7.1.2 Drug Administration 
The infusion of CPX-351 (cytarabine:daunorubicin) Liposome Injection will be 
performed through a central venous catheter, using an infusion pump to ensure that the 
drug is infused over the specified time period.  Non-DEHP containing administration sets 
should be used.  Do not use an in-line filter.  CPX-351 should never be given by the 
intramuscular or subcutaneous route.  Administer CPX-351 over approximately 90 
minutes via an infusion pump.  Flush the line to ensure administration of the full dose. 
 
The dosage (total units and u/m2), start/stop time of the infusion, total volume infused, 
must be documented in the patient’s chart. 
 
7.2 
Drug Accountability 
The study pharmacist or designee must maintain records of the delivery of CPX-351 to 
the study site, the inventory at the site, the use by each patient, and the disposition of 
unused product. These records should include dates, quantities, lot numbers, expiration 
dates and patient identifications.  The institution should maintain records that document 
adequately that patients were provided the doses specified by the protocol and reconcile 
all investigational product received from the manufacturer.  Records of storage conditions 
(temperature logs) must be kept for the entire period that CPX-351 is maintained at the 
institution.  Unused or expired drug will be disposed per MDACC policy.

Dose Reductions and Delays 
Induction doses are not reduced.  Consolidation doses are 65 units/m2 on days 1 and 3.  In 
instances with prolonged myelosuppression or other medical conditions where the 
investigator feels further dose reduction might be required, 50 units/m2 on days 1 and 3 
may be used after discussion with PI and sponsor and documentation of rationale.  
Patients with evidence of delayed recovery from cytopenias or acute toxicities following 
induction or consolidation (>56 days) may have consolidation doses delayed by up to 2 
weeks to permit recovery.   Any doses missed or delayed due to toxicity may be 
administered as soon as the patient has recovered from the toxicity.  Toxicities will be 
graded using the CTCAE Version 4.0 (See APPENDIX 5: Common Terminology 
Criteria for Adverse Events V4.0 (CTCAE)).   
7.4 
Concomitant Therapy 
7.4.1 Premedication 
Nausea and vomiting: 
Patients may receive prophylaxis or therapy for nausea and/or vomiting according to 
institutional standards. 
 
Hypersensitivity/Infusion-related reactions: 
Patients will not be routinely pre-medicated for hypersensitivity or infusion-related 
reactions initially during the first infusion of the first treatment course.  If the patient 
develops a hypersensitivity reaction then he/she should be pre-medicated at all 
subsequent infusions. 
 
7.4.2 Suggested guidelines for management of hypersensitivity reactions: 
 
Mild symptoms (e.g., mild flushing, rash, pruritus): 
Stop infusion and supervise at bedside with monitoring of vital signs 
Reinitiate infusion slowly (halving the rate of infusion) +/- premedication 
 
Moderate symptoms (e.g. moderate rash, flushing, mild dyspnea, chest discomfort): 
Stop infusion and give IV diphenhydramine, 20-25 mg (or equivalent) and IV 
dexamethasone 10 mg. 
Do not reinitiate infusion.  Subsequent doses should be administered with premedication 
(e.g., IV diphenhydramine, 20-25 mg (or equivalent) and IV dexamethasone 10 mg) and 
may be given at the same dose and rate.  
 
Severe/life-threatening symptoms (e.g. hypotension requiring vasopressor therapy, 
angioedema, respiratory distress requiring bronchodilation therapy, generalized 
urticaria): 
Stop infusion.  Administer IV diphenhydramine and dexamethasone as indicated above.  
Add epinephrine (adrenaline) or bronchodilators if indicated.  Do not reinitiate infusion.  
Do not retreat.  Report this event as a serious adverse event.

FINAL 
If hypersensitivity or infusion-related reactions become a clinically relevant toxicity, then 
premedication for hypersensitivity reactions will be instituted with drugs, doses and 
schedule according to each investigator’s preference.  Additionally, a decision may be 
made to prolong the infusion time to two hours or more. 
 
7.4.3 Permitted therapy 
Patients may receive ongoing supportive and palliative care (e.g. pain control) as 
clinically indicated throughout the study. 
 
Infection Prophylaxis:  Prophylactic use of anti-infectives is highly recommended during 
the period of profound neutropenia until ANC returns to 500/μL or greater. The choice of 
anti-infectives will be according to institutional protocol. Use of anti-infective agents as 
prophylaxis and treatment must be documented on the case report forms. 
 
Growth Factor support: The use of growth factors will be according to institutional 
protocol and/or according to ASCO criteria.(14) Use of growth factors must be 
documented on the case report forms. 
 
Transfusion support:  The use of transfusion support (RBCs and platelets) will be 
according to institutional protocol.  Use of transfusion support must be documented on 
the case report forms. 
 
7.4.4 Therapy that is not permitted 
Other anti-cancer treatment and other investigational therapy(ies) are not permitted 
during the Treatment Phase.  In the event of persistent disease or relapse the patient may 
receive other anti-leukemic therapies. Administration of isolated doses of intrathecal 
chemotherapy is allowed.  
 
7.5 
Duration of Protocol Treatment 
Patients may continue on study provided they have not met the criteria for 
discontinuation of therapy (See Section 5.2).  The table below summarizes the expected 
duration of the Treatment Phase.  Patients may receive up to two induction courses 
followed by consolidation courses.  After the Treatment Phase, patients are followed until 
death.

follow-up are censored on the date they were last known to be alive.  
8.3 
Event-free Survival 
All enrolled patients are assessed for Event-free survival. Event-free survival is defined 
as the time from study registration to the date of induction treatment failure (persistent 
disease), relapse from CR or CRi, initiation of non-protocol chemotherapy (e.g. salvage 
therapy), or death from any cause, whichever comes first.  Patients transferred to 
transplant will be censored for Event-free Survival at the start of conditioning therapy.  
Patients alive and not known to have any of these events are censored on the date they 
were last examined.

FINAL 
8.4 
Response Assessment Criteria 
During the Treatment Phase patients will be assessed for response according to the 
following criteria(15): 
Complete remission 
(CR)1 
Bone marrow blasts <5%; absence of blasts with Auer 
rods; absence of extramedullary disease; absolute 
neutrophil count >1.0 x 109/L (1000/μL); platelet count 
>100 x 109/L (100,000/μL). 
CR with incomplete 
recovery (CRi)2 
All CR criteria except for residual neutropenia (<1.0 x 
109/L [1000/μL]) and/or thrombocytopenia (<100 x 109/L 
[100,000/μL]) 
Treatment failure 
 
Persistent Disease (PD) 
 
Failure to achieve CR or CRi; only includes patients 
surviving ≥7 days following completion of initial 
treatment, with evidence of persistent leukemia by blood 
and/or bone marrow examination 
Death in aplasia 
Deaths occurring ≥7 days following completion of initial 
treatment while cytopenic; with an aplastic or hypoplastic 
bone marrow obtained within 7 days of death, without 
evidence of persistent leukemia 
Death from 
indeterminate cause 
Deaths occurring before completion of therapy, or <7 days 
following its completion; or deaths occurring ≥7 days 
following completion of initial therapy with no blasts in 
the blood, but no bone marrow examination available 
Relapse3 
Bone marrow blasts ≥5% (confirmed); or confirmed, 
sustained reappearance of blasts in the blood after 
achievement of a CR or CRi, not considered due to 
recovery from chemotherapy; or development of 
extramedullary disease 
1All criteria need to be fulfilled; marrow evaluation should be based on a count of 200 nucleated cells in an 
aspirate with spicules; if ambiguous, consider repeat exam after 5 to 7 days; flow cytometric evaluation 
may help to distinguish between persistent leukemia and regenerating normal marrow; a marrow biopsy 
should be performed in cases of dry tap, or if no spicules are obtained; no minimum duration of response 
required. 
2Some patients may not achieve complete hematologic recovery prior to initiation of consolidation.  CRi 
usually cannot be declared earlier than Day 42 to allow for adequate time for documentation of peripheral 
blood recovery.  Consolidation usually begins no earlier than 42 days after the last induction course. 
3In cases with low blast percentages (5-10%), a repeat marrow should be performed to confirm relapse. 
Appearance of new dysplastic changes should be closely monitored for emerging relapse. In a patient who 
has been recently treated, dysplasia or a transient increase in blasts may reflect a chemotherapy effect and 
recovery of hematopoiesis. 
 
The response of patients with no post-baseline bone marrow assessment is entered as not 
done. 
8.4.1 Timing of response assessment 
In general, the patient’s response to induction therapy is made on the first day when all 
criteria for CR or treatment failure are met.  The bone marrow assessment and the

CONFIDENTIAL 
Page 38 of 61 
FINAL 
peripheral counts are not required to be performed on the same day but recovery of 
counts (including absence of peripheral blasts) must be performed within 14 days of the 
bone marrow assessment.   
 
8.4.2 Best Response 
Patients who complete the induction(s) with a response of CRi may be upgraded to a CR 
during or after consolidation if the patient’s peripheral blood counts meet the criteria for 
CR after declaration of a CRi.  To upgrade a response to CR both peripheral blood and 
bone marrow assessment must be obtained within a 14 day period and all criteria for CR 
must be met. 
8.5 
Remission Duration 
Only patients achieving CR or CRi are assessed for remission duration (relapse-free 
survival). Remission duration is measured from the date of achievement of a remission 
(CR/CRi) until the date of relapse or death from any cause; patients not known to have 
relapsed or died at last follow-up are censored on the date they were last examined. 
8.6 
Morphologic Leukemia-free State 
All randomized patients that have at least one evaluable post-randomization bone marrow 
assessment performed on or after Day 14 after the last induction are assessed for 
morphologic leukemia-free state.  Morphologic leukemia-free state is defined as bone 
marrow blasts <5% AND absence of Auer rods and/or extramedullary disease. 
9.0 Assessment of Safety 
 
9.1 
Evaluable for Safety 
All patients who have received at least one dose will be considered evaluable for safety. 
9.2 
Adverse Events 
9.2.1 Definition of an Adverse Event 
An adverse event is any untoward medical occurrence in a patient or clinical 
investigation subject administered with a pharmaceutical product and which does not 
necessarily have to have a causal relationship with this treatment. An adverse event can 
therefore be any unfavorable and unintended sign (including an abnormal laboratory 
finding, for example), symptom, or disease temporally associated with the use of a 
medicinal product, whether or not considered related to the medicinal product. This 
includes worsening of a pre-existing condition or increase in frequency of a pre-existing 
condition. An adverse event is considered serious if it meets any of the serious criteria 
listed in Section 9.2.2.  To ensure no confusion or misunderstanding of the difference 
between the terms “serious” and “severe”, which are not synonymous, the following 
clarification is provided: 
 
The term “severe” is often used to describe the intensity (severity) of a specific event (as 
in mild, moderate, or severe myocardial infarction); the event itself, however, may be of 
relatively minor medical significance (such as severe headache). This is not the same as

FINAL 
“serious”, which is based on patient/event outcome or action criteria usually associated 
with events that pose a threat to a patient’s life or functioning. Seriousness (not severity) 
serves as a guide for defining regulatory reporting obligations. 
 
Adverse events are to be recorded in the case report form from the start of the infusion on 
Day 1 until 30 days after the last dose of study drug, with the exception of serious 
adverse events. (See Section 9.2.2).  Leukemia Department Guidelines for AE recording 
will be used. 
 
The Investigator or physician designee is responsible for verifying and providing source 
documentation for all adverse events and assigning the attribution for each event for all 
subjects enrolled on the trial. 
 
Adverse events and protocol specific data will be entered into CORe/PDMS.  
CORe/PDMS will be used as the electronic case report form for this protocol. 
 
Adverse drug reactions (ADRs) are all noxious and unintended responses to a medicinal 
product related to any dose that a causal relationship between the medicinal product and 
an adverse event is at least a reasonable possibility, i.e., the relationship cannot be ruled 
out. An unexpected ADR is any adverse reaction not identified in nature or intensity in 
the current Investigator’s Brochure. 
9.2.2 Serious Adverse Event Reporting 
An adverse event or suspected adverse reaction is considered “serious” if, in the view of 
either the investigator or the sponsor, it results in any of the following outcomes: 
 
 Death 
 A life-threatening adverse drug experience – any adverse experience that places the 
patient, in the view of the initial reporter, at immediate risk of death from the 
adverse experience as it occurred. It does not include an adverse experience that, 
had it occurred in a more severe form, might have caused death. 
 Inpatient hospitalization or prolongation of existing hospitalization 
 A persistent or significant incapacity or substantial disruption of the ability to 
conduct normal life functions. 
 A congenital anomaly/birth defect. 
 
Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered a serious adverse drug experience when, based upon 
appropriate medical judgment, they may jeopardize the patient or subject and may require 
medical or surgical intervention to prevent one of the outcomes listed in this definition. 
Examples of such medical events include allergic bronchospasm requiring intensive 
treatment in an emergency room or at home, blood dyscrasias or convulsions that do not 
result in inpatient hospitalization, or the development of drug dependency or drug abuse 
(21 CFR 312.32).

 Important medical events as defined above, may also be considered serious adverse 
events. Any important medical event can and should be reported as an SAE if 
deemed appropriate by the Principal Investigator or the IND Sponsor, IND Office. 
 All events occurring during the conduct of a protocol and meeting the definition of 
a SAE must be reported to the IRB in accordance with the timeframes and 
procedures outlined in “The University of Texas M. D. Anderson Cancer Center 
Institutional Review Board Policy for Investigators on Reporting Serious 
Unanticipated Adverse Events for Drugs and Devices”.  Unless stated otherwise in 
the protocol, all SAEs, expected or unexpected, must be reported to the IND 
Office, regardless of attribution (within 5 working days of knowledge of the event). 
 All life-threatening or fatal events, that are unexpected, and related to the study 
drug, must have a written report submitted within 24 hours (next working day) of 
knowledge of the event to the Safety Project Manager in the IND Office.   
 Unless otherwise noted, the electronic SAE application (eSAE) will be utilized for 
safety reporting to the IND Office and MDACC IRB.  
 Serious adverse events will be captured from the time of the first protocol-specific 
intervention, until 30 days after the last dose of drug, unless the participant 
withdraws consent. Serious adverse events must be followed until clinical recovery 
is complete and laboratory tests have returned to baseline, progression of the event 
has stabilized, or there has been acceptable resolution of the event. 
 Additionally, any serious adverse events that occur after the 30 day time period 
that are related to the study treatment must be reported to the IND Office. This may 
include the development of a secondary malignancy. 
 
Reporting to FDA: 
 Serious adverse events will be forwarded to FDA by the IND Sponsor (Safety 
Project Manager IND Office) according to 21 CFR 312.32. 
 
It is the responsibility of the PI and the research team to ensure serious adverse 
events are reported according to the Code of Federal Regulations, Good Clinical 
Practices, the protocol guidelines, the sponsor’s guidelines, and Institutional Review 
Board policy. 
 
9.2.3 Communication between Investigator and Jazz Pharmaceuticals 
The Investigator must send all SAEs (initial and follow up) that require collection and 
reporting per protocol, and which occur in a patient who received CPX-351, to Jazz 
Pharmaceuticals within 1 business day of their awareness of the SAE via email to 
AEreporting@jazzpharma.com.  In addition, all other adverse events must be reported to 
Jazz in summary of line-item form upon Jazz’s request.   
 
Follow-up information is sent either via a new Serious Adverse Event Form (stating that 
this is a follow-up), or via the original one form (with the new information highlighted 
and a new date provided).  The follow-up should describe whether the event has resolved

or continues, if and how it was treated, whether the patient continued or discontinued 
study participation.   
 
The telephone and fax numbers of the local Clinical Research contact person and the 
contact person in the local department of Clinical Safety, specific to the site, must be 
listed in the investigator folder provided for each individual site and provided to the 
manufacturer at the start of the trial.  Questions referring to a specific serious adverse 
event occurring in a study patient should be directed to the local Clinical Research 
contact person specified in the investigator folder provided for the site. 
 
9.3 
Cardiac Toxicity Monitoring 
As anthracyclines are known to have an adverse effect on cardiac function, each patient’s 
cardiac function will be monitored through the Treatment and Follow-up Phases.  Any 
left ventricular ejection fraction below 50% will be recorded as adverse events.  If the left 
ventricular ejection fraction is reduced >10% to below 50% from the baseline assessment 
at the last Treatment Phase measurement, left ventricular ejection fraction will continue 
to be monitored every 3 months until a return to baseline or 1 year, whichever comes 
first. 
9.4 
Laboratory Data 
Laboratory data obtained according to the schedule of assessments will be recorded on 
the CRF or other data collection instrument. Only laboratory data requested by the 
protocol need be recorded unless specific findings result in a clinical event such as an 
adverse event or documentation of peripheral blood count recovery.   These results will 
be collected. 
9.4.1 Copper Assessment 
Patients will have serum copper assessed routinely and the percentage of patients with 
persistent (>1 year) copper elevations will be reported.  Also, patients with persistently 
elevated serum copper will be evaluated for clinical abnormalities associated with copper 
toxicity (e.g. unexplained increase in liver function tests).  Serum copper elevations are 
laboratory values and are not reported as adverse events unless associated clinical signs 
and symptoms of copper toxicity.  
 
MDACC will draw the serum copper, send it out for processing and will report the results 
in clinic station in approximately 4 days.   
10.0 Statistical Considerations(16, 17) 
 
General Description: 
This is a Phase II study of CPX-351 Liposome Injection in newly diagnosed AML patients 
with high risk of induction mortality.  Two dose levels (50 units/m2 and 75 units/m2) of 
CPX-351 will be studied initially. The primary objective is to evaluate treatment response. 
The efficacy outcome is CR or CRi within two induction cycles.  A maximum of 30 patients 
will be equally randomized to the two dose levels. A Bayesian method by Thall et al (1995)

will be used for futility and toxicity monitoring. After 15 patients have been accrued to 
each dose level, an assessment of overall safety/dose limiting toxicities and efficacy will 
be made and one dose level will be chosen for further study. OR if both dose levels are safe 
and further dose escalation seems possible, one additional cohort with a dose of 100 
units/m2 will be open. A maximum of 15 patients will be enrolled in this arm and the same 
toxicity and futility monitor rules will be applied. After 2 or 3 dose levels have been 
studied, one dose levels will be chosen for further study. An expansion cohort of 10 patients 
will be treated at the dose level with a favorable response and/or toxicity profile for further 
evaluation for safety and efficacy. Consequently, the preferred dose level has 25 patients 
evaluable. 
 
Additional 25 patients will be added to the arm with the dose of 100 units/m2, the sample 
size for this arm will be up to 40, and the maximum number of patients for all three arms 
will be up to 80. 
 
Multc Lean software version 2.1 developed in the Department of Biostatistics MDACC 
was used for the study design.  
 
The study will monitor futility and toxicity, and the monitoring rules will be applied to 
each dose separately.  If study in one of the two doses is stopped early due to futility or 
excessive toxicity, all the future patients will be enrolled in the open dose arm (i.e.,  without 
randomization).  In the case the lower dose (50 units/m2) has been shown to be too toxic 
at an interim look (thus stop further patient enrollment) the higher dose (75 units/m2) will 
also stop accrual.   
 
Futility monitoring: 
Treatment success is defined as achievement of CR or CRi. We will accrue a maximum of 
15 patients at each dose level and test the null hypothesis that the true response is at most 
5% (meaning little or no activity) versus the alternative hypothesis that the true response 
is 30% or greater, independently in each treatment arm. Assuming that the success rate is 
binomially distributed, this design with 15 patients in each arm has 87% power and a one-
sided type I error rate of 0.05 using an exact test.  
 
 To monitor futility, the study in one dose level will be stopped early if the data in that dose 
level suggest that: 
 
                                     Pr(E <0.25 + S |data)>0.95 
 
That is, if at any time during the study we determine that there is a greater than 95% chance 
that the response rate is less likely to improve by 25% than the null hypothesis in one dose 
level, we will terminate the enrollment in that dose. Here E  represents the response rate 
for experimental drug in this study and  S represents the response rate for the standard 
practice (null hypothesis).  We assume that S has a distribution of beta (10, 190) to reflect 
the information on 200 patients for the historical data, which has a mean response rate of 
0.05 and a variance of 0.0002.  We also assume that E has a non-informative flat prior 
beta(0.1, 1.9) with mean of 0.05 and variance of 0.0158.

The futility stopping boundaries for the overall response based on these assumptions and 
monitoring condition is shown in table 7. For example, accrual will be stopped in one dose 
if there is no response observed in the first 5 patients treated in that dose. 
 
The toxicity monitoring/efficacy summary will be submitted to the IND Office Medical 
Monitor (Dr. Agueda Cohen) for every 5 subjects treated in each Arm (per Table7, 8, 11 
& 12).

Toxicity monitoring 
In addition, toxicity will be monitored closely. Denote the probability of toxicity by TE, 
where toxicity is defined as DLTs. We assume toxicity rate beta (0.66, 1.34) for the 
experimental treatment in this study.  Our safety monitoring rule is described as follows: 
Pr(TE > 0.33 | data)  > 0.85. That is, we will stop the enrollment in one dose if, at any time 
during the study, we determine that there is more than 85% chance that the DLT rate is 
more than 33% in that dose. Stopping boundaries corresponding to this stopping rule is 
listed in table 8. For example, the enrollment in one dose will be stopped if the first 4 of 
the first 5 patients experienced toxicity in that dose.

The operating characteristics for this design are presented in table 9. If the enrollment in 
one dose continues until 15 patients are evaluated in each arm and 5 CR or CRi are 
observed, then the 95% credible interval for the response rate would be (11.6%, 47.7%).

The arm with a favorable toxicity profile and/or a favorable might be chosen for further 
evaluation by expanding a cohort of 10 additional patients in that arm. We will use the 
same criteria (e.g. expansion will be stopped if Pr(TE > 0.33 | data)  > 0.85) to monitor 
toxicity for the expansion cohort by using a total sample size of 25 for the winner arm. The 
stop boundaries are summarized in the following table. If 10 or more patients out of the 1st 
20 patients experienced DLT, the trial will be stopped and no expansion cohort will be 
evaluated.  If 10 or more patients out of 20 patients experienced DLT (by adding 5 more 
patients to the 15 patients in that arm), the expansion will be stopped.

the response rate for the standard practice (null hypothesis).  TE represents DLT rate. For 
trial simulation, we use the same assumption for prior distributions listed above for each 
parameter. That is, S has a prior distribution of beta (10, 190), E has a non-informative

Data analysis will be performed using SAS or S-plus, as appropriate. For each arm, the 
CR/CRi rate and the DLT rate will be estimated with95% confidence intervals. The intent-
to-treat patients will be used for the primary efficacy analysis, patients who lost-to-follow 
up in the first 2 cycles will be treated as failures.   Patients who received at least one dose 
of the treatment drug will be evaluable for toxicity outcomes. In addition, Fisher’s exact 
test will be used to compare the response rate and toxicity rate between the two dose levels. 
For the exploratory objectives, Fisher’s exact test will be used to compare immune 
responses between different doses of CPX-351.  Two-sample t test or ANOVA or Fisher’s 
exact test will be used to check the association between Troponin – T and cardiotoxicity, 
and t test or ANOVA will be used to compare the apoptosis of ex-vivo cultured leukemia 
cells.

16.0 APPENDIX 6: Immune resonstitution after chemotherapy with CPX-351 
Immune reconstitution is believed to constitute a major element that determines the risk 
of relapse and the possibility of late infectious complications. Immune reconstitution after 
standard cytarabine and anthracycline combination has not been well studied and not at 
all after therapy with CPX-351. To this effect we propose the following: 
 
To determine how  CPX-351 influences the recovery of functional pathogen-specific 
and leukemia-specific immune responses. 
We will conduct analyses of T cell phenotype, estimate antigen-specific T cell precursor 
frequencies (by intracellular cytokine flow cytometry and peptide/dextramer staining) 
and determine antigen-specific cytokine production capacity (cytokine bead array assay). 
We will evaluate antigen-specific T cell recovery following treatment with CPX-351 by 
analyzing 1) Immunophenotypic recovery of Th1, Th2, Th17 and regulatory T cells; 2) 
The number and function of recovering CMV and Flu-specific T cells capable of 
responding functionally to in vitro stimulation with overlapping pools of peptide by 
intracellular cytokine detection; 3) The number and function of T cells capable of 
responding to leukemia-associated antigens including proteinase 3 (PR3), Wilms tumor 
antigen (WT1) and cancer testis antigens (e.g. PRAME) will be assessed following 
stimulation with overlapping pools of peptide and intracellular cytokine assay. 
 
To determine how CPX-351 influences the recovery and function of NK cells 
To evaluate if CPX-351 will impact on NK phenotype and function, we will conduct 
longitudinal analyses of NK phenotype and function during CPX-351 therapy. 
Quantitative 10-color flow cytometric analysis will be performed to 1) characterize the 
functional phenotype of NK cells using an extended panel of antibodies against activating 
(NKp30, NKp44, NKp46, NKG2D, NKG2C, DNAM1) and inhibitory receptors 
(NKG2A and KIRs); 2) assess the effector function of NK product against MHC class I-
deficient leukemia targets and primary AML cells from the recipient by intracellular 
cytokine assay for interferon-gamma (IFN-γ) production, chemokine production 
including CCL3 (MIP1α) and CCL4 (MIP1β) and cytotoxicity, including CD107a 
degranulation and 51chromium release assay; Confocal microscopy will be used to 
directly assess the immune synapse formation with leukemia targets. 
 
Sample collection and distribution 
60 cc of blood (Green top tubes- heparin) and 5 cc in purple top (EDTA) to be collected 
at 3 time points: 
1- Before induction with CPX-351 
2- At recovery from induction, just prior to consolidation #1 
3- At recovery from 1st cycle of consolidation just prior to consolidation #2 
Samples will be sent to Dr. Katy Rezvani’s lab manager, P14.3144; tel: 713-745-0027.

APPENDIX 7: Early Detection of CPX-351-induced cardiotoxicity using high 
sensitivity troponin T 
Chemotherapy is an effective treatment in most cancers. Yet all these drugs have a 
various range of side effects. Chemotherapy-induced organ injury remains a major issue 
in cancer patient care. Chemotherapy-induced cardiotoxicity is the most serious one, 
particularly associated with the use of anthracyclines, ultimately impacting the long-term 
cancer survivors and survival time. CPX-351 is a liposomally encapsulated combination 
of cytarabine and daunorubicin. The liposomal encapsulation may lead to a decrease in 
cardiac toxicity. However, the CPX-351-induced cardiotoxicity has not been evaluated.  
 
Identification of chemotherapy-induced cardiac toxicity has been dependent on imaging 
modalities, such as echocardiogram or MUGA scan.  Despite their usefulness, routine 
cardiac imaging alone lacks sensitivity for early detection of subclinical cardiac disease.  
Multiple cardiac biomarkers have been evaluated extensively in both animal models and 
clinical studies such as creatine kinase (CK), creatine kinase – MB fraction (CK-MB), 
troponin T (cTnT), troponin I (cTnI), brain natriuretic peptide (BNP), C-reactive protein 
(CRP), and interleukin family member (ST2).5, 6  In acute coronary syndromes, troponin 
is one of the most well established biomarkers used to guide diagnosis and treatment.  
However, the utility of biomarkers in monitoring myocardial damage secondary to 
chemotherapy is still controversial.   
 
Both cTnT and cTnI have been demonstrated in multiple clinical studies to be sensitive 
and specific markers for detecting myocardial injury after chemotherapy administration.  
The level of troponin released into circulation has a good predictive value for subsequent 
decrease in LV ejection fraction and adverse cardiac events long before the impairment is 
observed by echocardiogram or symptoms have developed.  Elevation in troponin has 
shown a positive predictive value of 50-84%, and a negative predictive value of 90-
99%.5, 7  Furthermore, the peak value and the duration of elevated troponin level have a 
strong relationship with the degree of LV dysfunction.  In contrast, BNP, NT-proBNP, 
CK, CK-MB and CRP have shown to be less sensitive and specific in detecting 
subclinical heart failure in this group of patients.8, 9  
 
Recent advances in assay technology have led to more sensitive and precise cardiac 
troponin T assays that can detect TnT level as low as 0.005 µg per liter.10  With 
increasing in sensitivity, high-sensitive troponin T (hs-TnT) has superiority over standard 
troponin test in early diagnosis of acute myocardial infarction.11  In chronic stable angina, 
higher levels of hs-TnT has been shown to be associated with the higher incidence of 
cardiovascular death and heart failure in the future.12  Recently, hs-TnT has been 
evaluated as a peri-operative risk stratification in non-cardiac surgery patients.13  
Interestingly, they found that hs-TnT level above universal cut-off were associated with a 
2.6-fold increase in in-hospital mortality and morbidities from cardiovascular system.

FINAL 
To our knowledge, no prior study has ever evaluated hs-TnT during CPX-351 
chemotherapy administration. Therefore, our primary objective is to assess whether hs-
TnT obtained during the course of CPX-351 chemotherapy could allow us to monitor the 
development of acute cardiotoxicity.   
 
 Primary objective:  
To test the feasibility of using high-sensitivity troponin T to monitor acute CPX-351-
induced cardiotoxicity. In addition, BNP and cardiac troponin I will be measured. 
 
 Roche high sensitivity troponin T assay is a sandwich chemiluminescent assay. High 
sensitivity troponin T assay gives detection limit of 5 ng/L and the 99th percentile of 
cutoff 14 ng/L. It can be run on MODULAR ANALYTICS E170, Elecsys 2010, 
cobas e411, cobas e 601 and cobas e 602 analyzers.  
 This high sensitivity troponin T assay will be measured on Cobas e601 using Roche 
reagents including calibrators and controls. 
 
Sample collection and distribution 
3 cc of blood (Green top tubes- heparin) at the following time points: 
1- Before the start of each cycle with CPX-351 (baseline) 
2- Approximately 24 hrs after the end of the first dose (Day 1 + 1) (for each cycle) 
3- Approximately 25 hrs after the end of the dose given on day 5 (Day 5 + 1) (for

APPENDIX  8:  Pharmacodynamic Investigations During CPX-351 Therapy 
 
The objectives of the pharmacokinetic and pharmacodynamic investigations during this 
clinical trial are as follows: 
 
(1) To test ex vivo cytotoxicity of combination of Pim kinase inhibitor(s) and CPX-351 on 
circulating leukemia cells.  
(2) To investigate effect of Pim kinase inhibitor on phosphorylated and total protein levels 
in pim kinase signaling pathway.   
 
Only patients entering at MD Anderson Cancer Center will be studied.  All patients with 
>5,000 WBC/l of peripheral blood will be requested to participate in the cellular 
pharmacodynamics studies.  Patients will sign consent forms to enter these investigations.   
 
Once a patient has consented to participate in the investigation, please contact Ms. 
Vrushali Datar (pager 713-606-2212) or Yuling Chen (pager 713-404-2550) in The 
Laboratory of Cellular and Molecular Pharmacology (Dr. Gandhi, phone, 713 792-3336) 
to coordinate scheduling of blood samples.  To facilitate preparedness for laboratory 
studies, please plan on initiating therapy in the subsequent morning if the clinical 
situation allows and please inform us as soon as there is a possibility of patient entering 
the clinical trial.     
 
Blood samples will be collected at the following times from patients in the Dose Escalation 
Phase:  Total of 2 samples will be collected. 
 
Cycle 1.     
Day 1:  0 (pre-dose),   
 
Two green top tubes (2  10mL) 
 
 
24 h 
 
 
 
One green top tube   (1  10mL) 
 
For the pre-dose (sample 1), two tubes of blood (10mL each) will be collected in a 
Vacutainer green top tube.  For the remaining sample (sample 2), one tubes of blood 
(10mL) will be collected in a Vacutainer green top tube.   The samples will be mixed and 
immediately put on ice-bath.  Samples will be brought to Dr. Gandhi’s laboratory in the 
Tan zone (T1.3839).   The blood will be centrifuged and plasma will be separated, 
transferred to storage tubes and immediately frozen, and stored until analysis.  After 
removal of plasma, the blood cells will be resuspended in PBS and AML blasts will be 
isolated by Ficoll-Hypaque density-gradient centrifugation procedures.  Cells will be used 
for the following laboratory endpoints.   
 
NOTE:  We may not be able to do all studies in every patient.  This will be decided based 
on diagnosis and number of leukemia cells recovered from the peripheral blood sample.   
 
Effect of ex-vivo combination with Pim kinase inhibitors on AML blasts during CPX-351 
therapy:  Pre-treatment leukemia cells or cells isolated during CPX-351 therapy will be 
cultured ex-vivo with varying concentrations of Pim kinase inhibitors to evaluate the effect 
of combined DNA damage and anthracyclines with Pim kinase inhibition on AML blasts.
