Brief summary:
This is a phase I study of temsirolimus (Torisel) combined with dexamethasone, cyclophosphamide and etoposide in patients with relapsed acute lymphoblastic leukemia (ALL), lymphoblastic lymphoma (LL) or peripheral T-cell lymphoma (PTL).

Detailed description:
Studies have shown that mTOR inhibitors (MTI) inhibit growth of pre-B and T-cell ALL cell lines in vitro and in ALL xenograft models. The MTI temsirolimus was chosen for use in this study due to its weekly intravenous dosing, its more predictable blood levels, and availability of a single-agent pediatric MTD and its sustained biologic effect due to conversion to sirolimus. This study will determine the maximum tolerated dose of temsirolimus that can given in combination with dexamethasone, cyclophosphamide and etoposide in relapsed ALL, LL or PTL. A standard 3-patient cohort dose-escalation design will be used. Response to treatment will be evaluated. Biology tests will be done to evaluate minimal residual disease (MRD), temsirolimus' effect on glucocorticoid resistance, and mTOR inhibition.

Arms: arm 1: This is the starting dose of temsirolimus at 7.5 mg/m\^2 given IV. First dose of temsirolimus will be administered on Day 1, followed immediately by the first dose of IV etoposide and IV cyclophosphamide. Etoposide (100mg/m\^2) and cyclophosphamide (440 mg/m\^2) are continued for the next four days (Day 1-5). A second dose of temsirolimus is given on Day 8. arm 2: If Dose Level 1 is tolerated, the study will escalate to Dose Level 2 following the dose escalation schedule. Dose Level 2 will be administered via IV at 10 mg/m\^2. First dose of temsirolimus will be administered on Day 1, followed immediately by the first dose of IV etoposide and IV cyclophosphamide. Etoposide (100mg/m\^2) and cyclophosphamide (440 mg/m\^2) are continued for the next four days (Day 1-5). A second dose of temsirolimus is given on Day 8. arm 3: If Dose Level 2 is tolerated, the study will escalate to Dose Level 3 following the dose escalation schedule. Dose Level 3 will be administered via IV at 15 mg/m\^2. First dose of temsirolimus will be administered on Day 1, followed immediately by the first dose of IV etoposide and IV cyclophosphamide. Etoposide (100mg/m\^2) and cyclophosphamide (440 mg/m\^2) are continued for the next four days (Day 1-5). A second dose of temsirolimus is given on Day 8. arm 4: If Dose Level 3 is tolerated, the study will escalate to Dose Level 4 following the dose escalation schedule. Dose Level 4 will be administered via IV at 25 mg/m\^2. First dose of temsirolimus will be administered on Day 1, followed immediately by the first dose of IV etoposide and IV cyclophosphamide. Etoposide (100mg/m\^2) and cyclophosphamide (440 mg/m\^2) are continued for the next four days (Day 1-5). A second dose of temsirolimus is given on Day 8. Temsirolimus will not be escalated beyond Dose Level 4.

 ABSTRACT  
 
One in five children with acute lymphoblastic leukemia (ALL) and non-Hodgkin lymphoma (NHL) will 
develop recurrent disease despite strategies of risk stratification and modern intensified chemotherapy. 
The combination of etoposide and cyclophosphamide is used widely in an attempt to salvage the 
refractory and relapsed lymphoblastic leukemia and lymphoma population. Therefore we propose a 
Phase 1 study to determine the feasibility and safety of adding two weekly doses of intravenous 
temsirolimus to standard ALL salvage therapy with 5 days of cyclophosphamide and etoposide.  
 
 
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase involved in signal transduction 
pathways which regulate cell growth and proliferation.1-3 While mutations in mTOR do not frequently occur 
in human cancer46, constitutive activation of signal transduction proteins related to the mTOR pathway 
(AKT kinase, S6K1, PI3K) or loss of proteins linked to mTOR (PTEN) are found in numerous 
malignancies.1, 3, 4 Studies have shown that mTOR inhibitors (MTI) inhibit growth of pre-B and T-cell ALL 
cell lines in vitro and in ALL xenograft models.5 In preclinical studies, ALL cell lines treated with 
temsirolimus showed synergism with many chemotherapeutic agents, including etoposide and 
dexamethasone.6 The PPTP found in vivo combinations of sirolimus and cyclophosphamide were more 
effective than either agent used alone.7  
 
The MTI temsirolimus was chosen for use in this study due to its weekly intravenous dosing, its more 
predictable blood levels, and availability of a single-agent pediatric MTD and its sustained biologic effect 
due to conversion to sirolimus.8

BACKGROUND 
 
 
2.1 
Introduction/Rationale for Development 
 
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase involved in 
signal transduction pathways which regulate cell growth and proliferation 1-3. Its activation 
triggers resting cells to increase the translation of a subset of messenger RNAs whose 
proteins are required for cell-cycle progression from the G1 to S phase of the cell cycle 
(reviewed in 1-3). While mTOR itself is not frequently mutated in human cancer, 
constitutive activation of signal transduction proteins related to the mTOR pathway (AKT 
kinase, S6K1, PI3K) or loss of proteins linked to mTOR (PTEN) are found in numerous 
malignancies.1-4   
 
One in five children with ALL will develop recurrent disease despite strategies of risk 
stratification and modern intensified chemotherapy. The prognosis for these patients is 
poor even with aggressive retrieval strategies with high dose chemotherapy and stem cell 
rescue.,9,10 Newer agents are needed to treat these patients. Biologically targeted cancer 
agents, including signal transduction inhibitors like mammalian target of rapamycin 
inhibitors (MTIs), have shown great promise in treating hematologic malignancies.2, 5, 11 
While signal transduction inhibitors may be efficacious as single agents, it is more likely 
that these targeted agents will demonstrate greater efficacy in combination with cytotoxic 
agents.  
 
 
 
2.1.1 
Rationale for Chemotherapy Backbone 
The combination of etoposide and cyclophosphamide is used widely in an 
attempt to salvage the refractory and relapsed lymphoblastic leukemia and 
lymphoma 
population. 
Using 
the 
3-[4,5-dimethyl-thiazole-2,5-diphenyl] 
tetrazolium bromide (MTT) cytotoxicity assay, both case/control and matched set 
comparisons of initial and relapse samples showed that relapse samples retain 
sensitivity to etoposide and cyclophosphamide, which are used minimally in front-
line protocols.12 Combining newer, targeted agents with known successful 
salvage therapies may potentiate response.  
 
 
2.2 
Preclinical Studies 
 
 
2.2.1 
Antitumor Activity 
Studies have shown that MTIs inhibit growth of B-precursor ALL lines in vitro, inducing 
apoptosis in both primary cell cultures 3 and NOD/SCID xenograft models.5 Testing of 
the mTOR inhibitor sirolimus by the Pediatric Preclinical Testing Program (PPTP) in vitro 
showed maximal inhibition of 5 ALL cell lines ranging from 23-77%, with all 3 T-cell ALL 
lines having maximal inhibition greater than 70%.7 In vivo rapamycin induced significant 
EFS differences in 5 of 8 ALL xenografts, including 2 of 2 T-cell ALL xenografts.7 
 
Synergism with Chemotherapy 
In preclinical studies, ALL cell lines treated with temsirolimus showed synergism with 
methotrexate, dexamethasone, L-asparaginase, etoposide and doxorubicin (Fig. 1). 6 
Figure 1 depicts MTT data for each drug combination in 1 representative cell line. Grey 
bars represent untreated, slashed bars represent MTI alone, black bars represent 
cytotoxic alone, and dotted bars represent combined effect. All data is normalized to 
untreated baseline (Y axis). Each group of 4 bars represents a combination with a 
different cytotoxic. MTIs had at least an additive effect when combined with methotrexate 
(MTX), dexamethasone (DEX), L-asparaginase (L-ASP), etoposide (VP-16), and 
doxorubicin (DOX). ALL cell lines treated with vincristine or cytarabine showed neither 
additive benefit nor antagonism.

Sirolimus has also been found to reverse glucocorticoid resistance in resistant lymphoid 
cell lines (Fig. 2).13 Wei et al. found that the mTOR inhibitor rapamycin sensitized lymphoid 
malignancy cells to glucocorticoid induced apoptosis via modulation of the antiapoptotic 
MCL1. MTIs also downregulate cyclin D1 leading to down-regulation of dihydrofolate 
reductase (DHFR) synthesis, possibly increasing sensitivity of ALL blasts to MTX.6

apoptosis 
 
 
As described in Section 2.2.1, studies have shown that MTIs inhibit growth of B-precursor 
ALL lines in vitro, inducing apoptosis in both primary cell cultures 3 and NOD/SCID 
xenograft models.5  
 
 
2.2.2 
Preclinical Pharmacokinetic Studies 
Repeat dose toxicity studies have demonstrated temsirolimus related changes in multiple 
organs and systems in rodents and non-rodents. These include lymphoid atrophy, and 
decreased lymphocytes, decreases in weight, size, and/or function of male reproductive

organs, increased cholesterol, and general inflammatory responses that included 
inflammation or rashes of the skin and increases in neutrophils, fibrinogen, and/or serum 
proteins. In addition, rodent-specific effects of temsirolimus included hyperglycemia, 
atrophy of female reproductive organs, myocardial degeneration and phospholipidosis. 
The pathogenesis of many of the changes is associated with the known antiproliferative 
effect of temsirolimus. The nature of changes and target organs were similar across 
studies, regardless of the duration of administration and were similar between IV and oral 
dosing. 
 
The pharmacokinetic profile of temsirolimus after IV and oral administration was 
established based on results from in vivo studies in mice, rats, monkeys, and humans. 
Temsirolimus is extensively converted to sirolimus in mice and humans. Less conversion 
occurs in rats and monkeys. Temsirolimus demonstrates 85-87% binding to plasma 
proteins at concentrations of 10-100 ng/mL, with an apparent concentration-dependent 
binding to erythrocytes. The primary metabolites of temsirolimus in rats and monkeys are 
hydroxytemsirolimus (M10) and secotemsirolimus (M4). Oral administration of 
temsirolimus resulted in a more extensive number of circulating metabolites with 
temsirolimus as the major circulating compound-related product in rat and monkey whole 
blood, followed by sirolimus as the next most abundant metabolite. There is evidence of 
more extensive metabolism in the feces of rats compared with blood and plasma, 
suggesting further biotransformation during elimination. The primary oxidative 
metabolism is via CYP3A4, indicating that inhibitors and inducers of CYP3A4 enzyme 
system may alter the metabolism of temsirolimus, although temsirolimus does not induce 
CYP3A4.

Adult Studies 
 
 
2.3.1 
Phase 1 Studies 
 
mTOR inhibitor in solid tumors: 
In a Phase 1 trial of single agent temsirolimus in adults with solid tumors, doses ranged 
from 7.5 to 220 mg/m2 weekly with no MTD determined.8 At the 34 mg/m2 and 45 mg/m2 
doses, one patient in each dose level had Grade 3 dose limiting toxicity (DLT) of 
thrombocytopenia; one also neutropenia and hypophosphatemia; the other had asthenia 
and diarrhea. Dose escalation continued to 220 mg/m2 where the DLTs included grade 3 
stomatitis, manic-depressive syndrome, transaminase elevation, and asthenia. At all 
dose levels, temsirolimus (and its hydrolysis product sirolimus) were in the range that 
inhibits cancer cell proliferation in vitro.8 
 
mTOR inhibitor in hematologic malignancies: 
A Phase 1/2 study of oral everolimus in adult patients with relapsed hematologic 
malignancies has also been reported.14 Twenty-seven patients (only 1 with ALL) received 
either 5 mg or 10 mg daily. No DLTs were noted although grade 3 toxicities occurring in 
more than 5% of patients included hyperglycemia (22%), hypophosphatemia (7%) and

Phase 1 Studies in Combination with Chemotherapy 
 
A variety of MTI’s have been studied in combination with other therapies; including 
interferon in renal cell carcinoma,15 hormonal agents in breast cancer,16 5-FU/LCV17, 
imatinib in gastrointestinal stromal tumors, gemcitabine, and sorafenib in adult tumors. 
Early data on MTI/chemotherapy combinations have sometimes shown potential 
enhancement of expected toxicities when compared to single agent use in patients with 
solid tumors. In the 5-FU/LCV/temsirolimus study, grade 4 mucositis/stomatitis was 
observed at the 45 mg/m2 level.17 Grade 3 toxicities noted in adult trials with temsirolimus 
have been rash, nausea/vomiting, cytopenias, hypophosphatemia, hypokalemia,

hyperglycemia, 
asthenia/neuropathy, 
fatigue, 
mucositis, 
hypercholesteremia/ 
hypertriglyceridemia, and dyspnea.15, 18-20 
 
The only published combination trial of an MTI and high-dose chemotherapy in leukemia 
is an adult AML Phase 1 dose escalation trial of oral daily sirolimus on a backbone of 
standard adult AML therapy consisting of 5 days each of mitoxantrone (8 mg/m2/d), 
cytarabine (1 gm/m2/d) and etoposide (100 mg/m2/d). This trial did not demonstrate an 
increased toxicity rate with the MTI/chemotherapy combination. One patient had a DLT 
attributed to prolonged aplasia (120 days) at a sirolimus dose of 15 mg load and 5 mg 
daily. In the prior 4 dose levels, the median time to ANC >500 mm3 was 27 days (range 
16-38). Overall sirolimus was well tolerated and did not increase non-hematologic toxicity 
of the backbone chemotherapy.21 
 
 
2.3.3 
Phase 2 Studies 
 
 
Phase 2 trials have also been conducted in a wide variety of tumors utilizing a flat dosing 
schedule of 25, 75 and/or 250 mg intravenously weekly with notable single agent activity 
in mantle cell lymphoma, breast cancer, and renal cell carcinoma.  Two phase 2 studies 
of single agent temsirolimus in adults with relapsed or refractory mantle cell lymphoma 
have been conducted.22, 23  Thirty-five patients were treated at a dose of 250 mg IV 
weekly. Objective responses were seen in 13 of 34 patients (one CR and 12 PR). The 
median time-to-progression in all patients was 6.5 months, and the median duration of 
response for the responders was 6.9 months. Twenty nine patients were treated at 25 mg 
IV weekly and responses were seen in 41% of patients (1 CR and 10 PR).  Hematologic 
toxicities were common, and thrombocytopenia was the most frequent cause of dose 
reductions. The thrombocytopenia was brief, however, with resolution typically observed 
within one week. Treatment at the lower dose was associated with similar response but 
less myelosuppression23  
 
A Phase 2 randomized, double-blind multicenter Phase 2 trial of temsirolimus has also 
been conducted in patients with advanced renal cell carcinoma. Patients (n=111) were 
treated with this drug as a single agent using doses of 25 mg, 75 mg or 250 mg IV 
weekly. The objective response rate was <10%, however time to progression was 
prolonged in the patients on this study compared to historical controls. Responses did not 
appear to be dose-dependent and the lowest dose was deemed capable of biologic 
activity. Therefore, the dose designated for further study was 25 mg IV weekly. The most 
frequently occurring drug related adverse events observed in patients on this study were 
rash (76%), mucositis (70%), asthenia (50%), and nausea (43%). The most frequently 
occurring > Grade 3 toxicities were hypophosphatemia (13%), anemia (9%), 
hyperglycemia (17%) and hypertriglyceridemia (6%). It has been suggested that the latter 
findings may be due to effects of the drug on signaling via insulin-associated pathways, 
and that changes in these laboratory parameters may serve as biomarkers of 
temsirolimus activity.24 
 
Subsequently, 626 patients with metastatic RCC and 3 or more adverse risk features 
were treated in a randomized Phase 2I trial with temsirolimus 25 mg intravenously weekly 
versus 18 million units IFN-α thrice weekly versus 15 mg temsirolimus intravenously 
weekly + 6 million units IFN-α thrice weekly. Patients treated with temsirolimus had a 
statistically significant longer survival than IFN-a patients (10.9 vs. 7.3 months, P= 
0.0069) with a 9% objective response rate in the temsirolimus monotherapy arm.25 Grade 
3 adverse events occurred in 67% of the temsirolimus group and included anemia, 
thrombocytopenia, hypercholesterolemia, hyperlipidemia, hyperglycemia, asthenia and 
dyspnea. Temsirolimus has also been combined with letrozole, 5 fluorouracil and 
leucovorin, and sorafenib with hyperglycemia, asthenia, rash, stomatitis, and hand-foot 
syndrome being the predominant toxicities.17, 26, 27

In a prostate cancer clinical trial, target phosphoprotein inhibition in tumor was seen in an 
oral dosing regimen at a dose equivalent to 7 mg IV weekly.28 In the oral everolimus trial 
nine patients had biologic samples of which 6 (including one responder) showed 
decreased phosphorylation of p70S6 and/or eIF4E-binding protein.14

Pediatric Studies 
 
 
2.4.1 
Prior Experience in Children  
 
mTOR inhibitor in solid tumors: 
A Phase 1 trial of single agent once weekly IV temsirolimus in children with advanced 
solid tumors had an MTD of 75 mg/m2.30 The DLT at the 150 mg/m2 dose was grade 3 
anorexia (1 pt) and grade 4 thrombocytopenia < 7 days (1 pt). Seven patients had ≥ 
grade 3 treatment-related adverse events: neutropenia, leukopenia, anemia, anorexia, 
thrombocytopenia, and increased ALT. Cmax was comparable to adult patients; 
temsirolimus area under the curve (AUC) was higher in children. Greater exposure to 
parent drug appeared balanced by shorter half-life and commensurate lower AUC of the 
sirolimus metabolite.  
 
A Children’s Oncology Group (COG) study of temsirolimus in combination with an 
antibody directed against the Type 1 insulin-like growth factor receptor (COG ADVL0813) 
is currently in progress. Another COG study of temsirolimus in combination with 
temozolomide and irinotecan (ADVL0918) is also in progress for recurrent pediatric solid 
tumors. In this study, both agents are being administered intravenously on a weekly 
basis. Results from both studies are not yet available. 
 
On COG ADVL1114, three weekly doses of temsirolimus were given in combination with 
the UK ALL R3 re-induction treatment backbone. 31 Dose de-escalation of the 
temsirolimus from 10mg/m2/dose to 7.5mg/m2/dose was required due to the DLTs of 
hypertriglyceridemia and persistent toxicity > Grade 2 (hypertension, GGT, and mucositis 
in a non-responding patient) on day 42 of therapy. At the lower dose, DLTs of grade 5 
sepsis, grade 3 ulcer and persistent GGT elevation at day 42 were identified. Significant 
infectious toxicity was noted in the relapsed ALL population. The study has been 
amended to decrease the number of doses of temsirolimus to 2 (on days 1 and 8) and 
intensive infection prevention guidelines have been added to the protocol. Of note, 
supportive care with g-csf was not permitted in ADVL1114.  
 
mTOR inhibitor in hematologic malignancies: 
An institutional Phase 1 trial of oral sirolimus monotherapy in 9 patients with relapsed 
acute leukemia has been published in abstract form.32 The initial dose level was that 
used for pediatric renal transplant patients, 9 mg/m2 load and 3 mg/m2 daily, with one 
escalation to 12 mg/m2 load and 4 mg/m2 daily. No DLTs were noted, and 3 ALL patients 
met the criteria for stable disease, one receiving 3 full courses of sirolimus 
monotherapy.32 
 
On a Dana-Farber institutional clinical trial, pediatric and adult patients with relapsed ALL 
were treated with a combination of sirolimus and glucocorticoids for 5 days prior to 
starting multiagent reinduction chemotherapy.  Changes in gene expression as well as 
biologic markers of a pro-apoptotic state, including MCL-1 levels, were compared with 
samples from ALL patients who were treated with glucocorticoids alone.  Of the 4 
assessable patients treated with the combination of sirolimus and corticosteroid, 3 
demonstrated a marked decrease in MCL-1 protein levels after initiation of therapy which 
was evident by 6 hours.  This was accompanied by a concomitant decrease in phospho-
S6 ribosomal protein levels, suggesting successful mTOR inhibition. Of 4 patients treated 
with corticosteroids alone, three demonstrated no change in MCL-1 or phospho-S6 
ribosomal protein levels. All patients treated with sirolimus and corticosteroids 
demonstrated a decrease in circulating blasts (>80% decrease from baseline) during the 
5 days of therapy.33

Pharmacology/Pharmacokinetics/Correlative Biological Studies 
 
 
In the pediatric solid tumor trial Western blot analysis of phosphorylated S6 and AKT 
proteins in peripheral blood mononuclear cells, confirmed temsirolimus 75 mg/m2 
significantly inhibited AKT pathway signaling in vivo.20 Inhibition was also seen at the 10 
and 25 mg/m2 dose levels but not in a consistently validated manner to serve as a 
pharmacodynamic endpoint.30 
 
In the pediatric hematologic malignancy single agent sirolimus trial reductions in 
phosphorylation of p70S6, AKT, STAT3 and STAT5 were seen, but did not correlate with 
dose or response in this limited number of patients.32 Similarly, while in vivo inhibition of 
target phosphoproteins was observed in several patients treated with temsirolimus on the 
COG ADVL1114 trial, these pharmacodynamic data also did not appear to correlate with 
clinical responses (Sarah Tasian, MD, private communication and Rheingold ASCO 
abstract 2015).

TREATMENT PROGRAM 
The following sections detail the treatment plan for each course of therapy.   
 
Due to a significantly increased risk of morbidity and mortality in children with multiply 
relapsed ALL undergoing intensive therapy, hospitalization from initiation of therapy until: 
1) there is evidence of ANC recovery defined as ≥ 200/microliter and increasing, and 2) 
they are afebrile and clinically stable. See Section 5.2 for highly recommended infection 
prevention guidelines. Please refer to the Drug Information section for additional administration 
guidelines. Treatment should begin within 3 calendar days of enrollment.   
 
4.1 
Treatment Course 
This is a Phase I feasibility pilot of temsirolimus in combination with five days of 
cyclophosphamide and etoposide.  After eligibility is determined, consent obtained, and 
registration occurs patients receive their first dose of temsirolimus on day 1, followed immediately 
by their first doses of etoposide and cyclophosphamide. Etoposide and cyclophosphamide are 
continued for the next four days (day 1-5). A second dose of temsirolimus is given on day 8.  A 
course is defined as 29 days. All patients should get two courses of therapy in the absence of 
progressive disease, dose limiting toxicity or investigator/subject preference to withdraw.   
 
Leukemia patients who are M1 and CNS1/2 and lymphoma patients with stable disease or better 
after the second course of therapy, may receive up to an additional six courses (for a total of eight 
courses) in the absence of relapse or progressive disease.

Disease Evaluations 
 
4.2.1 
Leukemia Patients 
All patients should have a bone marrow aspirate/biopsy, lumbar puncture, and CBC to assess 
response on day 29 +/- 3 days as needed for scheduling reasons.   
 
 
A bone marrow procedure need not be performed if the patient has an absolute blast 
count (ABC) greater than or equal to 2,500/mm3 in the peripheral blood on day 29. 
 
 
If the bone marrow is hypoplastic or M1 but counts have not recovered to ANC ≥ 500 and 
PLTS ≥ 50,000 (without transfusion) obtain a weekly CBC and perform a bone marrow 
with evidence of count recovery (ANC ≥ 500 and PLTS ≥ 50,000) or day 42; whichever is 
first. A repeat bone marrow does not need to be performed if the patient subsequently 
develops an absolute blast count (ABC) greater than or equal to 2,500/mm3   
 
 
If the marrow is M2 by aspirate (assessed by morphology and/or flow cytometry) or the 
bone marrow biopsy shows 5-25% residual leukemia (assessed by morphology or 
immunohistochemistry), then proceed to course 2 regardless of ANC and PLT count after

all grade 3 or 4 non-hematologic toxicities have returned to grade 2 or less.   
 
 
If the marrow is M3 or has more blasts than the pre-study bone marrow, has progression 
in any extramedullary site, or if the patient is CNS 3 at day 29, discontinue protocol 
therapy and proceed with alternative treatment. The one exception to this is patients who 
are CNS 3 solely due to chloromas or cranial nerve findings and are CNS 1/2 by LP who 
have had at least a partial response in that area.  
 
 
A lumbar puncture with cytospin should be done on day 29 +/- 3 days to assess CNS 
status. Course 2, Day 1 Intrathecal chemotherapy can be given at this time if ANC ≥ 500 
and PLTS ≥ 50,000µL. 
 
4.2.2 
Lymphoma Patients 
All patients should have a CBC, bone marrow aspirate or biopsy (ONLY if positive at study entry), 
lumbar puncture (ONLY if positive at study entry), and imaging of known sites of disease on day 
29 +/- 3 days as needed for scheduling reasons. 
 
NHL patients who were bone marrow positive at study entry 
 
If the marrow is hypoplastic or M1, and counts have not recovered to ANC ≥ 500 and 
PLTS ≥ 50,000 (without transfusion) repeat marrow and CBC weekly until recovery or 
progression. 
 
 
If the marrow is M2 by aspirate (assessed by morphology and/or flow cytometry) or the 
bone marrow biopsy shows 5%-25% residual lymphoblasts (assessed by morphology or 
immunohistochemistry), then proceed to course 2 regardless of ANC and PLT count after 
all grade 3 or 4 non-hematologic toxicities have returned to grade 2 or less.  
  
 
If the marrow is M3 or has more blasts than the pre-study bone marrow, has progression 
in any extramedullary site, or if the patient is CNS 3 at day 29 discontinue protocol 
therapy and proceed with alternative treatment. The one exception to this is patients who 
are CNS 3 solely due to chloromas or cranial nerve findings and are CSF negative who 
have had at least a partial response in that area.

4.5 
Dose-Limiting Toxicity (DLT)   
 
Toxicity will be graded using the CTCAE criteria, version 4.03. The CTCAE provides descriptive terminology 
and a grading scale for each adverse event listed.  A copy of the CTCAE can be downloaded from the 
CTEP home page (http://ctep.cancer.gov). Any dose-limiting toxicity (DLT) should be reported 
immediately through the TACL Operations Center to the Study Chair.   
 
DLT will be evaluated during Course 1 only. 
 
DLT will be defined as any of the following events that are at least (possibly, probably or definitely) 
attributable to temsirolimus. The DLT observation period for the purposes of dose-escalation will be the 
first cycle of therapy (max 42 days). 
 
  
4.5.1 
Non-hematological dose-limiting toxicity 
 
4.5.1.1 Any grade 3, 4 or 5 non-hematologic toxicity that occurs any time after the first dose of 
temsirolimus and is at least possibly attributable to temsirolimus, with the following 
exceptions: 
 
Grade 3 or 4 fever, febrile neutropenia or infection, +/- hospitalization.  
 
Grade 3 gastrointestinal symptoms (anorexia, nausea, vomiting, and diarrhea) 
that resolve to ≤ grade 2 or baseline by day 36 of therapy. 
 
Grade 3 or 4 AST/SGOT, ALT/SGPT, or GGT that returns to ≤ Grade 2 or 
baseline within 36 days of the start of therapy.

 
Grade 3 constitutional symptoms (fatigue, malaise, weight loss, dehydration) that 
resolve to ≤ grade 2 or baseline by day 36 of therapy. 
 
Grade 3 or 4 hyperglycemia controllable by diet, oral diabetic drug and/or insulin 
that resolves to ≤ grade 2 within 96 hours of an intervention. If hyperglycemia is 
not controllable (≤ grade 2) by diet modification, insulin therapy and an oral 
diabetic agent it will be considered a DLT. 
 
Grade 3 or 4 metabolic/laboratory abnormalities (Na, K, HCO3, Ca++, PO4, 
creatinine and uric acid) attributable to tumor lysis syndrome (including tumor 
lysis syndrome itself) or its treatment that resolve to ≤ grade 2 or baseline by day 
36 with or without the use of supplementation or appropriate replacement 
therapy. 
 
Grade 3 or 4 asymptomatic electrolyte abnormalities that returns to ≤ Grade 2 or 
baseline within 36 days of the start of therapy 
 
Grade 3 or 4 hypofibrinogenemia 
 
Grade 3 albumin 
 
Grade 3 or 4 fasting hypertriglyceridemia or fasting hypercholesterolemia that 
returns to ≤ Grade 2 within 4 weeks of starting lipid lowering medication.  (See 
Section 4.6.1.7).  
 
Grade 3 or 4 non-fasting hypertriglyceridemia or hypercholesterolemia.  If Grade 
3 or 4 non-fasting hypertriglycerdemia or hypercholesterolemia is detected when 
routine (non-fasting) laboratory studies are performed, the test should be 
repeated within 3 days in the fasting state to permit accurate grading.  
 
Grade 3 hypertension that resolves to (≤ Grade 2) with appropriate use of anti-
hypertensives.  
 
Grade 3 mucositis/stomatitis. (See Section 4.6.1.6. for supportive care guidelines 
for mucositis). 
 
4.5.1.3 If a patient develops grade 3 or 4 pneumonitis attributable to temsirolimus the 
subsequent dose of temsirolimus will be held regardless of course.  This will be 
considered a DLT in Course 1 of therapy.  
 
 
 
4.5.1.4 Allergic reactions that necessitate discontinuation of study drug will not be 
 
considered a dose-limiting toxicity. 
 
4.5.1.5  Any Grade 3 or 4 toxicity that requires a dose of temsirolimus to be held in Course 1 will 
be considered a dose-limiting toxicity. Toxicities attributable to temsirolimus that do not resolve to 
≤ Grade 2 by day 36 will be considered dose-limiting toxicities. 
 
4.5.2 
Hematological dose limiting toxicity 
Bone marrow aplasia: > 42 days from Day 1 of therapy will be a DLT. Aplasia is defined as the 
failure to recover a peripheral ANC of > 500/mm3 and PLT > 20,000/mm3 in the absence of 
persistent leukemia. 
 
 
4.6 
Dose Modifications  
 
4.6.1 Dose Modifications of Temsirolimus for Non-Hematological Toxicity 
 
A Study Co- Chair must be notified of any temsirolimus dosage modification.  
 
4.6.1.1 Patients who have any dose-limiting non-hematological toxicity (as defined in Section 
4.5.1) will have subsequent doses of temsirolimus held until the toxicity resolves to  ≤ 
grade 2 or as otherwise indicated in the specific dose modifications below . The dose of 
temsirolimus will be restarted at one dose level below (or 5 mg/m2 if at dose level 1). 
Missed doses of temsirolimus should not be made up. The etoposide and 
cyclophosphamide should be continued as long as those drugs are not directly 
attributable to the toxicity.  If a DLT occurs but the patient meets requirements to receive

a subsequent course, the dose of temsirolimus will be restarted at one dose level below 
(or 5 mg/m2 if at dose level 1). If tolerated subsequently the dose can be increased back 
up to the original assigned dose. 
 
4.6.1.2 If a non-hematological toxicity recurs in a second course after one dose reduction, the 
patient will receive no further doses of temsirolimus. Patient may complete backbone 
chemotherapy as long as the other chemotherapeutic agents are not implicated in the 
toxicity or move on to other therapy per investigator choice. 
 
4.6.1.3 Dose modification for hyperglycemia: 
Therapy modifications for patients who develop hyperglycemia (based on random, non-
fasting glucose levels) should be: 
 
Hyperglycemia Grade 
Action 
Grade 1-2 
Continue temsirolimus 
Grade 3 
 
 Continue temsirolimus at same dose and initiate diet or 
TPN modification, insulin therapy and/or oral diabetic 
agent* as indicated.  
 The patient should continue to receive concomitant insulin 
and/or an oral diabetic agent for the management of 
hyperglycemia while on protocol therapy. Due to the 
residual effects of temsirolimus on blocking intracellular 
glucose uptake by inhibition of Glut1 transport and the long 
half life of temsirolimus, initial therapy with insulin may not 
work.  Early use of an oral diabetic agent is suggested. 
Grade 4 
 
 Initiate diet or TPN modifications, insulin and/or oral 
diabetic therapy as indicated. 
 Hold temsirolimus until resolves to ≤ Grade 3 
 Resume temsirolimus at same dose IF patient is 
asymptomatic AND serum glucose is consistently < 250 
mg/dL (≤ Grade 2). The patient may continue to receive 
concomitant insulin and/or an oral diabetic agent for the 
management of hyperglycemia while receiving 
temsirolimus. 
 If Grade 4 hyperglycemia recurs despite diet modification, 
and a stable dose of insulin, and an oral diabetic agent, 
then any subsequent doses of temsirolimus should be held. 
 
*Recommended guidelines for use of oral diabetic agents: Initiation of treatment 
for hyperglycemia should occur under the guidance of a pediatric endocrinologist 
at the local institution. Metformin or other oral anti-hyperglycemia agent may be used 
per local endocrinologist’s recommendations. Insulin therapy should be directed by 
specialists in pediatric diabetes, with the goal of normal fasting blood sugars < 126 mg/dL 
and HgbA1C < 8%. 
 
4.6.1.4 Dose modification for infusional reactions to temsirolimus 
 
Therapy modifications for patients who develop infusional reactions to temsirolimus should be: 
 
Grade 
Action 
Grade 1 
Transient flushing or rash, 
drug fever < 38◦ C (<100.4 ◦ F) 
And 
Grade 2 
Rash, flushing, urticaria, 
dyspnea, drug fever ≥ 
 
If a patient develops a hypersensitivity reaction despite 
diphenhydramine pretreatment, stop the infusion and wait 
30 to 60 minutes (depending upon the reaction severity). At 
the physician’s discretion, it may be possible to resume 
treatment by administering an H2 blocker approximately 30 
minutes before restarting the infusion. The manufacturer 
recommends famotidine 0.5 mg/kg IV maximum dose 20

Epinephrine or bronchodilators should be administered as 
indicated. Hospital admission for observation may be 
indicated 
 
Discontinue temsirolimus treatment 
 
4.6.1.5 Dose modifications for pneumonitis 
For patients who develop pneumonitis (cough, dyspnea, fever), temsirolimus should be held 
pending investigation. If events are considered at least possibly due to treatment, discontinue 
temsirolimus therapy.  If the treating clinician determines that respiratory symptoms are not 
related to drug therapy or are infectious in nature, the patient should be retreated with the same 
dose of temsirolimus once symptoms resolve.    
 
4.6.1.6 Dose modifications for mucositis or rash 
The following guidelines should be used for patients who develop mucositis, or rash. In addition, 
stomatitis, mucositis, and/or mouth ulcers due to temsirolimus (inflammation or ulcers in the 
mouth) should be treated using local supportive care (See Section 5.2.7 for specific 
recommendations).

temsirolimus should be held until recovery to ≤ Grade 3.  
Further lipid lowering medication options should be discussed 
with institutional hyperlipidemia consultants.  Upon recovery to ≤ 
Grade 3 cholesterol, temsirolimus should be restarted at the 
next lower dose level.  If the patient is being treated on the 
lowest dose level, temsirolimus therapy should be discontinued.

The following guidelines should be used for patients who develop elevated fasting 
triglycerides.   
 
Grade 
Action 
Grade 2-3 
 
 If on intralipids, repeat level after intralipids have been held at 
least 12 hours.  
 Continue temsirolimus; if triglycerides are between 301 and 400 
mg/dL consider treatment with an HMG-CoA reductase inhibitor 
depending upon recommendations of institutional 
hyperlipidemia consultants.  HMG-CoA reductase inhibitor is 
highly recommended if triglycerides are > 400. 
 It is expected that optimal effects of the lipid lowering 
medication will be observed 2-4 weeks after its initiation.  
Treatment with temsirolimus can continue during this time 
provided that hypercholesterolemia remains ≤ Grade 3 
Grade 4 
 Hold temsirolimus until recovery to  ≤ Grade 3 
 An HMG-CoA reductase inhibitor should be started, and 
dosages should be adjusted based upon recommendations 
from institutional hyperlipidemia consultants 
 Treatment with temsirolimus can continue during this time 
provided that hypercholesterolemia remains ≤ Grade 3 
 Upon retreatment with temsirolimus concurrent with an HMG-
CoA reductase inhibitor, if Grade 4 elevations recur, 
temsirolimus should be held until recovery to ≤ Grade 3.  
Further lipid lowering medication options should be discussed 
with institutional hyperlipidemia consultants.  Upon recovery to 
≤ Grade 3, temsirolimus should be restarted at the next lower 
dose level.  If the patient is being treated on the lowest dose 
level, protocol therapy should be discontinued. 
 
 
4.6.2  Dose Modifications of Cyclophosphamide for Non-Hematological Toxicity 
 
Hematuria: Omit in the presence of macroscopic hematuria. If there is a history of previous significant 
hematuria, hydrate before cyclophosphamide until specific gravity is < 1.015 and hydrate at 
125 mL/m2/hr for 24 hours after dose. Give IV Mesna (200 mg/m2) 15 minutes before the 
cyclophosphamide and repeat at hours 3, 6, and 9. Mesna may also be given by continuous infusion. 
 
Renal Dysfunction: If creatinine clearance or radioisotope GFR is < 10 mL/min/1.73 m2, reduce dose of 
cyclophosphamide by 50%. Prior to dose adjustment of cyclophosphamide, the creatinine clearance 
should be repeated with good hydration. 
 
4.6.3  Dose Modifications of Etoposide for Non-Hematologic Toxicity 
 
Allergic Reaction: Treat per institutional protocol. Consider premedication with diphenhydramine (1-2 
mg/kg slow IV push) and/or hydrocortisone 100-300 mg/m2. Continue to use premedication before 
etoposide for subsequent doses. Also consider substituting an equimolar amount of Etoposide 
phosphate, in the face of significant allergy and/or hypotension. Etoposide phosphate is a water soluble 
prodrug that does not contain polysorbate 80 and polyethyleneglycol, the solubilizing agent in etoposide 
that may induce allergic reactions and hypotension. Etoposide phosphate is rapidly converted to 
etoposide in vivo and provides total drug exposure, as represented by AUC (0-infinity),that is statistically 
indistinguishable from that measured for etoposide at equimolar doses. 
 
Hypotension: If blood pressure decreases during infusion slow infusion rate per institutional guidelines, 
and consider normal saline bolus or other IVF.  Suggested management includes: if diastolic or systolic 
blood pressure (BP) falls 20 mm Hg during infusion, reduce infusion rate by 50%. Start a simultaneous

30
infusion of NS 10 mL/kg if BP fails to recover or falls further. Stop infusion if BP does not recover, 
continue NS. If the patient has had any episode of hypotension, prehydrate with 0.9% NaCl at 10 
mL/kg/hr for 2 hours prior to any subsequent infusion. 
 
Renal Insufficiency: If renal function decreases, adjust etoposide as follows: CrCl 10-50 mL/min/1.73 m2, 
decrease dose by 25%; if CrCl < 10 mL/min/1.73 m2, decrease dose by 50%. 
 
Hyperbilirubinemia: If direct bilirubin is > 2 mg/dL, decrease dose by 50%. If direct bilirubin is 
> 5 mg/dL, hold etoposide. 
 
4.6.4 Dose Modifications of Intrathecal Therapy 
 
Systemic toxicity: The dosage for IT chemotherapy will not be reduced for systemic toxicity 
(myelosuppression, mucositis, etc.) and all patients will get leucovorin rescue post intrathecals containing 
methotrexate.  
 
Dose modifications following an episode of acute neurotoxicity: 
Following an acute neurotoxic event, a history and physical exam should guide the differential diagnosis. 
A neurology consult may be of value and should be considered. Seizures and other transient events may 
be linked to fever, infection, encephalitis, meningitis, hypertension, electrolyte disturbance, hypoglycemia, 
trauma, intracranial hemorrhage or thrombosis, narcotic withdrawal, illicit drug use, or other causes in 
addition to the direct side effects of chemotherapy. Appropriate laboratory studies may include, but are 
not limited to, blood cultures, a CBC, electrolytes, including glucose, calcium, magnesium and 
phosphorus, renal and liver function studies and/or an examination of the CSF. Imaging studies may 
include a CT scan and/or an MRI. The CT is commonly normal, in the absence of stroke, but if 
calcifications are present, this finding may be indicative of a more severe mineralizing 
leukoencephalopathy.   MRI abnormalities may be pronounced, but transient. Posterior reversible 
encephalopathy may be present on MR with extensive diffusion abnormalities, but these do not appear to 
correlate with subsequent demyelination or gliosis.  Additional studies, including MR angiography and/or 
venogram should be considered, if clinically indicated (e.g. focal deficits). 
 
Many acute events are temporally related to the administration of intrathecal therapy, commonly 9 to 11 
days after the IT administration.  Following an acute event, with recovery, there are few data to support or 
guide therapeutic interventions. It is reasonable to hold the next dose of IT therapy, or, substitute IT Ara-
C/hydrocortisone for 1 dose of IT MTX, or triple IT therapy or IT MTX if the toxicity appeared attributable 
to IT AraC..  
 
Hydrocephalus, microcephaly or known abnormality of CSF flow precluding intrathecal chemotherapy via 
lumbar puncture:  Intraventricular chemotherapy via Ommaya catheter may be used in place of 
intrathecal therapy delivered by LP. Intraventricular chemotherapy should be given according to the same 
schedule, but at 50% of the corresponding age-based doses that would be given by LP. NOTE: 
Obstruction to CSF flow may be a contraindication to intrathecal and/or intraventricular therapy. 
 
Viral, bacterial, or fungal meningitis: Omit until resolved. 
 
 
4.7  
Drug Interactions 
 
4.7.1 
CYP3A4 Inducers and Inhibitors 
The use of potent inhibitors and inducers of CYP3A4 should be avoided (see below and Appendix 
II). Aprepitant is an inducer, a moderate inhibitor, and substrate of CYP3A4 and should not be 
used as an anti-emetic. Antifungal agents should be avoided unless a fungal infection is 
diagnosed. In particular, systemic imidazole antifungal agents (voriconazole, posaconazole, 
itraconazole, fluconazole, etc.) should be avoided due to their strong inhibition of temsirolimus 
metabolism, therefore leading to higher temsirolimus exposure. Azoles may be started safely 7 
days post a dose of temsirolimus, but must be stopped 5 days prior to a subsequent dose of 
temsirolimus. Topical antifungal agents, amphotericin, or caspofungin/micafungin are preferred if

an infection is diagnosed. Similarly, antiviral agents such as acyclovir should be avoided unless a 
viral infection is diagnosed. The macrolide group of antibiotics should be avoided. 
 
The use of enzyme inducing anticonvulsants is not permitted while on study. Neither Gabapentin 
nor Levetiracetam induce hepatic drug metabolizing enzymes and may be suitable alternative 
anticonvulsant. 
 
The use of the following medications should be discontinued prior to initiation of protocol 
therapy and should be avoided during protocol therapy if reasonable alternatives exist.

4.7.2 Other Pharmacodynamic Interactions 
 
An increased risk of angioedema is possible in pateints taking mTOR inhibitors in combination 
with Ramipril and/or amlodipine. Caution should be used whem temsirolinus is given concomitantly with a 
calcium channel blocker (i.e., amlodipine) or ACE inhibitor (i.e.ramipril).

5.0 
SUPPORTIVE CARE   
 
Best supportive care and treatment will be given as appropriate to each patient (antiemetics, antibiotics, 
transfusions, oxygen therapy, nutritional support, palliative treatment for pain or cough, etc.). Patients may 
experience profound myelosuppression and immune suppression during this time. Caregivers must also be 
made aware that patients may experience very rapid clinical deterioration and hospitalization for course 1 is 
highly recommended (See Section 5.2.1).  
 
5.1  
Concurrent Therapy   
 
5.1.1 
Anti-cancer Therapy 
Concurrent anti-cancer therapy not defined within this protocol, including chemotherapy, radiation 
therapy, immunotherapy, or biologic therapy may NOT be administered to patients receiving study 
drug. If these treatments are administered the patient will be removed from protocol therapy. 
 
 
5.1.2  
Investigational Agents 
No other investigational agents may be given while the patient is on protocol therapy. 
 
5.1.3 
Growth Factors 
Growth factors that support white cell number or function may be administered on day 9 or after 
at the discretion of the treating physician for infection, ICU level care, Grade 3/4 mucositis, 
ulceration, or poor wound healing. Neulasta is permitted on study.  
 
5.2  
Infection Control 
Patients with relapsed ALL have a significant risk of morbidity and mortality with intensive salvage 
therapy. Patients in first relapse have a 4-5% induction mortality rate, the majority associated with 
infection. They have also been found to have a 45% rate of Grade 3 and 4 infection during re-
induction on recent COG ALL trials 33 (and personal communication T. Horton, E. Raetz, and M. 
O’Brien), and other relapsed ALL re-induction trials.34-36 Therefore patients with multiply relapsed 
ALL require a very aggressive approach to infection prevention and treatment as outlined below: 
 
5.2.1 
Hospitalization 
Due to the substantial risk of infection in patients with relapsed ALL receiving intensive 
salvage therapy, it is strongly recommended that they remain hospitalized from the 
initiation of therapy until: 1) there is evidence of ANC recovery defined as ≥ 200/microliter 
and increasing, and 2) they are afebrile and clinically stable.  
 
5.2.2 
Bacterial Prophylaxis 
It is strongly recommended that patients receive broad spectrum gram positive and 
negative antibiotic prophylaxis at initiation of induction therapy and until they have met  
the criteria for discharge outlined in 5.2.1. The specific choice of prophylactic antibiotics 
should be guided by the individual institution, although levofloxacin is recommended.37,38 
 
5.2.3 
Fungal Prophylaxis 
Prophylactic anti-fungal therapy with IV caspofungin, micafungin or amphotericin is also 
highly recommended.  The patient should remain on prophylactic anti-fungals until their 
ANC has fallen and is 200/microliter and rising and the patient is afebrile and clinically 
stable.  Note: Azole antifungals are not permitted until 7 days after the final dose of 
temsirolimus. (See Section 4.7.1)  
 
5.2.4 
Fever and Neutropenia 
Empiric broad spectrum antibacterial and anti-fungal therapy should be initiated 
immediately for patients with an ANC < 500/microliters (or < 1000 /microliters and falling) 
and an oral temperature > 38°C on two occasions within 12  hours or ≥ 38.5°C once or as 
clinically indicated. Broad-spectrum antibacterial antibiotics and anti-fungals, once 
started, should be continued until there is evidence of ANC recovery. If clinical symptoms 
or radiographic evidence of enterocolitis or typhilitis develop, broad spectrum coverage 
for gram negatives, anaerobes and an anti-fungal is highly recommended. Surveillance 


 
 
 
Protocol  Amendment #2 
1-18-2018 
 
CONFIDENTIAL 
 
 
TACL Internal Distribution Only 
33
radiographic imaging surveillance for sites of infection should also be performed as 
clinically indicated. 
 
5.2.5 
Empiric Management of Pulmonary Infiltrates 
Consideration should be given to evaluating pulmonary infiltrates with bronchoscopy and 
biopsy, lavage or open lung biopsy. If a procedure cannot be tolerated, begin empiric 
treatment with antifungal therapy given the high likelihood of fungal disease. Empiric 
coverage should be initiated per local institutional guidelines with consideration of 
bacterial, fungal, Pneumocystis jiroveci pneumonia (PJP, formerly called PCP) and 
legionella etiologies pending culture results. If fungal pulmonary disease is documented, 
surveillance radiographic imaging studies of the sinuses, abdomen/pelvis and brain are 
indicated. 
 
5.2.6 
Pneumocystis jiroveci Pneumonia Prophylaxis 
It is recommended that all patients receive prophylaxis for PJP (formerly called PCP).  
Options include trimethoprim/sulfamethoxazole (TMP-SMX) for two sequential days each 
week at a dose of 2.5 mg/kg/dose TMP-SMX (maximum dose of 160 mg) twice daily 
(BID) or according to institutional policy, unless they have a documented sulfa allergy. 
Options for sulfa-allergic patients include intravenous or nebulized monthly pentamidine 
or atovaquone per institutional standards. PJP prophylaxis should be continued 
throughout the entire study period. 
 
5.2.7 
Management of Mucositis/Perirectal Cellulitis 
Based on pilot experience and the intensity of this regimen, episodes of Grade 3-4 
mucositis and perirectal cellulitis are anticipated. Mucositis should be managed with IV 
hydration and hyperalimentation if indicated, effective analgesia, broad-spectrum gram-
positive and gram-negative antibiotic therapy and empiric antiviral and antifungal therapy 
as indicated. See Section 4.6.1.6 for recommendations for early local care for 
mucositis/stomatitis. Management of perirectal cellulitis should include broad-spectrum 
antibiotic therapy with dual gram-negative coverage as well as anaerobic coverage and 
supportive care  per institutional protocol.

5.3  
Supportive Care 
 
 
Appropriate antibiotics, blood products, antiemetics (except for aprepitant, see Section 4.7.1), anti-
hypertensives, fluids, electrolytes, and tumor lysis precautions and general supportive care are to be 
used as necessary. See Section 4.6 for dose modifications of therapeutic agents based upon toxicity. 
 
 
5.3.1 
Recommendations for care of stomatitis, mucositis and/or mouth ulcers: 
 ● Grade 1 - use conservative measures such as non-alcoholic mouth wash or 
salt water (0.9%) mouth wash several times a day until resolution. 
 
● Grade 2 or 3 - topical analgesic mouth treatments (i.e., local anesthetics such as 
benzocaine, butyl aminobenzoate, tetracaine hydrochloride, menthol, orphenol) may be 
used with or without topical corticosteroids, such as 
triamcinolone oral paste 0.1% (e.g. Kenalog in Orabase®). Agents containing hydrogen 
peroxide, iodine, and thyme derivatives may worsen mouth ulcers and should not be 
used. 
 
● If Grade 3 or higher mucositis develops after the second dose of temsirolimus initiate 
use of G-CSF or neulasta.  
 
Topical antifungal agents (nystatin) amphotericin or echinocandins (eg, caspofungin or 
micafungin) are preferred if an oral infection is diagnosed. Similarly, prophylactic antiviral 
agents such as acyclovir should be avoided due to interaction with temsirolimus unless a 
viral infection is diagnosed. Systemic imidazole antifungal agents (ketoconazole, 
fluconazole, traconazole, etc.) should be avoided due to their strong inhibition of 
temsirolimus metabolism until 7 days post a dose of temsirolimus or 5 days prior.   
 
● If due for IT therapy when any grade mucositis is present, the use of leucovorin 5 
mg/m2/dose every 12 hours x 2 doses, beginning 48 hours after the IT therapy, is 
encouraged. 
 
 
 
 
5.3.2 
Tumor Lysis: 
It is recommended, but not mandated, that all subjects start allopurinol 150 mg/m2 
divided TID or urate oxidase (0.1mg/kg IV) prior to the initiation of therapy. Serum 
chemistries, including electrolytes, BUN, Cr, and uric acid, should be monitored at least 2 
times per week for the first week. If there is no evidence of tumor lysis the patients may 
then get routine chemistry labs as described in Section 7.0. If a patient’s peripheral 
leukemic blast count is  20,000 or if they have bulk lymphomatous disease it is highly 
recommended, although not mandated, that they are admitted to the hospital for IV 
hydration and close monitoring for metabolic abnormalities and renal insufficiency due to 
tumor lysis syndrome. 
 
 
5.3.3 
Infusional Reactions: 
Anaphylactic precautions should be observed during temsirolimus administration. 
Patients should receive premedication with diphenhydramine (1 mg/kg, max 50 mg) prior 
to each temsirolimus dose. See Section 4.6.1.4 for management and dose modification 
guidelines for infusional reactions. 
 
 
 
5.3.4 
Blood Products 
Investigators should follow institutional guidelines regarding administration of blood 
products. Platelets must be 20,000 in order to receive temsirolimus.

DRUG INFORMATION 
 
6.1 
Temsirolimus (CCI-779, Torisel®, Rapamycin analog, WAY-130779) 
(NSC#683864, IND#61010) 
 
6.1.1 
Nomenclature and Molecular Structure 
The chemical name is Sirolimus 42-ester with 2,2-bis (hydroxymethyl)-propionic acid. The molecular 
formula is C56H87NO16. The molecular weight is 1030.30 daltons.  
 
6.1.2 
Mode of Action and Pharmacology 
Temsirolimus [an ester of the immunosuppressive compound sirolimus, (rapamycin, Rapamune®)] blocks 
cell cycle progression from the G1 to the S phase by binding to the intracellular cytoplasmic protein, 
FK506 binding protein (FKBP)12.  This complex inhibits activity of the enzyme mTOR (mammalian target 
of rapamycin), inhibiting translation of several key proteins that regulate progression through the G1 
phase in response to growth factors.  Sirolimus, temsirolimus's major metabolite, also binds to FKBP12. 
 
Classification: mTOR inhibitor 
 
Approximate Solubility (at 25ºC): Very soluble in ethanol.  Soluble in phosal 50 PG, octanol, propylene 
glycol, polyethylene glycol (PEG) 400, triacetin,  polyethylene  glycol (PEG) 200, labrosol, and 
polysorbate 80.  Insoluble in miglyol 812, olive oil and water. 
 
Incompatibilities: Avoid contact of the diluted product with polyvinyl chloride (PVC) equipment or devices 
that are plasticized with di- (2-ethylhexyl)pthalate (DEHP) to prevent DEHP leaching.  Store diluted 
temsirolimus solutions in bottles (glass) or plastic bags (polyolefin or polypropylene).   
 
Infusion sets containing polyvinyl chloride should not be used to administer temsirolimus to avoid leaching 
of plasticizer.  
 
The following are examples of in-line filters that are compaitible with temsirolimus: 
 
• 
IV 6200 Disposable I.V. Filter 0.2 micron by EPS®, Inc  
 
• 
IV 6120 Disposable I.V. Filter 1.2 micron by EPS®, Inc

LV 5000 Large Volume 5 micron Conical Filter by B.Braun  
 
• 
Baxter Paclitaxel Set with 0.22 micron filter  
 
• 
Codan 0.2 micron monofilter 
 
Other polyethersulfone filters may be used. 
 
Potential Drug Interactions: Temsirolimus is a CYP3A4 substrate.  Avoid concomitant treatment of 
temsirolimus with potent CYP3A4 inhibitors and agents that have CYP3A4 induction potential (See 
Appendix II).  
 
The combination of temsirolimus and sunitinib resulted in dose limiting toxicity at low doses of both 
agents.  Avoid concomitant sunitinib during temsirolimus treatment.   
In vitro, temsirolimus inhibited CYP2D6, CYP3A4, and CYP3A5 activity.  It inhibited 
 
paclitaxel metabolism, but did not significantly affect 5-fluorouracil metabolism.    
 
 
Temsirolimus and warfarin may interact to increase INR.  
 
 
Patient Care Implications:  For hypersensitivity prophylaxis, see Section 5.6.1.4. 
 
 
Vaccinations:  Avoid the use of live vaccines during temsirolimus treatment.

Preparation and Administration 
 
Solution Preparation 
These mixing instructions apply to commercial TORISEL only (as is provided for this study). The 
investigationally labeled product used in other studies is mixed differently. 
 
Protect from excessive light. 
 
Follow this two steps dilution process (TORISEL should only be diluted with the supplied diluent): 
 
 
Step 1 
 
Inject 1.8 mL of DILUENT for TORISEL into the vial of TORISEL injection (25 mg/mL).  Due to the 
intentional 0.2 mL overfill in the TORISEL injection vial, the resulting drug concentration will be 10 mg/mL.  
A total volume of 3 mL will be obtained.  Mix well by gentle inversion of the vial.  DO NOT SHAKE. Allow 
sufficient time for air bubbles to subside.

6.2 
Etoposide  (Vepesid®, Etopophos®,VP-16) NSC #141540 
 
6.2.1  
Source and Pharmacology:  
A semisynthetic derivative of podophyllotoxin that forms a complex with topoisomerase 2 and DNA which 
results in single and double strand DNA breaks. Its main effect appears to be in the S and G2 phase of 
the cell cycle. The initial t½ is 1.5 hours and the mean terminal half-life is 4 to 11 hours. It is primarily 
excreted in the urine. In children, approximately 55% of the dose is excreted in the urine as etoposide in 
24 hours. The mean renal clearance of etoposide is 7 to 10 mL/min/m² or about 35% of the total body 
clearance over a dose range of 80 to 600 mg/m². Etoposide, therefore, is cleared by both renal and non 
renal processes, i.e., metabolism and biliary excretion. The effect of renal disease on plasma Etoposide 
clearance is not known. Biliary excretion appears to be a minor route of etoposide elimination. Only 6% or 
less of an intravenous dose is recovered in the bile as etoposide. Metabolism accounts for most of the 
non renal clearance of etoposide. 
 
The maximum plasma concentration and area under the concentration time curve (AUC) exhibit a high 
degree of patient variability. Etoposide is highly bound to plasma proteins (~94%), primarily serum 
albumin. Pharmacodynamic studies have shown that etoposide systemic exposure is related to toxicity. 
Preliminary data suggests that systemic exposure for unbound etoposide correlates better than total 
(bound and unbound) etoposide. There is poor diffusion into the CSF < 5%. 
 
Cmax and AUC values for orally administered etoposide capsules consistently fall in the same range as 
the Cmax and AUC values for an intravenous dose of one-half the size of the oral dose. The overall mean 
value of oral capsule bioavailability is approximately 50% (range 25-75%).  
 
Etoposide phosphate is a water soluble ester of etoposide which is rapidly and completely converted to 
etoposide in plasma. Pharmacokinetic and pharmacodynamic data indicate that etoposide phosphate is 
bioequivalent to etoposide when it is administered in molar equivalent doses.

6.2.3  
Formulation and Stability 
Etoposide for Injection is available as a 20 mg/mL solution in sterile multiple dose vials (5 mL, 25 mL, or 
50 mL each). The pH of the clear, nearly colorless to yellow liquid is 3 to 4. Each mL contains 20 mg 
etoposide, 2 mg citric acid, 30 mg benzyl alcohol, 80 mg modified polysorbate 80/tween 80, 650 mg 
polyethylene glycol 300, and 30.5 percent (v/v) alcohol. Vial headspace contains nitrogen. Unopened 
vials of etoposide are stable until expiration date on package at controlled room temperature (20˚-25˚C or 
68˚-77˚F). Etoposide phosphate for injection is available for intravenous infusion as a sterile lyophilized 
powder in single-dose vials containing etoposide phosphate equivalent to 100 mg etoposide, 32.7 mg 
sodium citrate USP, and 300 mg dextran 40. Etoposide phosphate must be stored under refrigeration (2°-
8°C or 36°- 46°F). Unopened vials of etoposide phosphate are stable until the expiration date on the 
package. 
 
 
6.2.4  
Guidelines for Administration 
 
Etoposide: Dilute etoposide to a final concentration ≤ 0.4 mg/mL in D5W or NS. Etoposide infusions are 
stable at room temperature for 96 hours when diluted to concentrations of 0.2 mg/mL; stability is 24 hours 
at room temperature with concentrations of 0.4 mg/mL. The time to precipitation is highly unpredictable at 
concentrations > 0.4 mg/mL. Use in-line filter during infusion secondary to the risk of precipitate 
formation. However, the use of an in-line filter is not mandatory since etoposide precipitation is unlikely at 
concentrations of 0.1-0.4 mg/mL. Do not administer etoposide by rapid intravenous injection. Slow 
rate of administration if hypotension occurs. Leaching of diethylhexyl phthalate (DEHP) from polyvinyl 
chloride (PVC) bags occurred with etoposide 0.4 mg/mL in NS. To avoid leaching, prepare the etoposide 
solution as close as possible, preferably within 4 hours, to the time of administration or alternatively as 
per institutional policy; glass or polyethylene-lined (non-PVC) containers and polyethylene-lined tubing 
may be used to minimize exposure to DEHP.

6.3 
Cyclophosphamide (Cytoxan) NSC #26271 
 
6.3.1  
Source and Pharmacology  
Cyclophosphamide is an alkylating agent related to nitrogen mustard. Cyclophosphamide is inactive until 
it is metabolized by P450 isoenzymes (CYP2B6, CYP2C9, and CYP3A4) in the liver to active 
compounds. The initial product is 4-hydroxycyclophosphamide (4-HC) which is in equilibrium with 
aldophosphamide which spontaneously releases acrolein to produce phosphoramide mustard. 
Phosphoramide mustard, which is an active bifunctional alkylating species, is 10 times more potent in 
vitro than is 4-HC and has been shown to produce interstrand DNA cross-link analogous to those 
produced by mechlorethamine. Approximately 70% of a dose of cyclophosphamide is excreted in the 
urine as the inactive carboxyphosphamide and 5-25% as unchanged drug. The plasma half-life ranges 
from 4.1 to 16 hours after IV administration.

Unknown Frequency and Timing: Fetal toxicities and teratogenic effects of cyclophosphamide (alone or in 
combination with other antineoplastic agents) have been noted in humans. Toxicities include: chromosomal 
abnormalities, multiple anomalies, pancytopenia, and low birth weight. Cyclophosphamide is excreted into 
breast milk. Cyclophosphamide is contraindicated during breast feeding because of reported cases of 
neutropenia in breast fed infants and the potential for serious adverse effects.

(L) Toxicity may also occur later. 
 
6.3.3  
Formulation and Stability  
Cyclophosphamide for injection is available as powder for injection or lyophilized powder for injection in 
500 mg, 1 g, and 2 g vials. The powder for injection contains 82 mg sodium bicarbonate/100 mg 
cyclophosphamide and the lyophilized powder for injection contains 75 mg mannitol/100 mg 
cyclophosphamide. Storage at or below 25ºC (77ºF) is recommended. The product will withstand brief

6.4 
IT Methotrexate (MTX, amethopterin, Trexall®) NSC #000740 
 
6.4.1 
Source and Pharmacology:  
A folate analogue which reversibly inhibits dihydrofolate reductase, the enzyme that reduces folic acid to 
tetrahydrofolic acid. Inhibition of tetrahydrofolate formation limits the availability of one carbon fragments 
necessary for the synthesis of purines and the conversion of deoxyuridylate to thymidylate in the 
synthesis of DNA and cell reproduction. The polyglutamated metabolites of MTX also contribute to the 
cytotoxic effect of MTX on DNA repair and/or strand breaks. MTX cytotoxicity is highly dependent on the 
absolute drug concentration and the duration of drug exposure. MTX is actively transported across cell 
membranes. At serum methotrexate concentrations exceeding 0.1 μmol/mL, passive diffusion becomes a 
major means of intracellular transport of MTX. The drug is widely distributed throughout the body with the 
highest concentration in the kidney, liver, spleen, gallbladder and skin. Plasma concentrations following 
high dose IV MTX decline in a biphasic manner with an initial half-life of 1.5-3.5 hours, and a terminal half 
life of 8-15 hours. About 50% is bound to protein. After oral administration, approximately 60% of a 30 
mg/m2 dose is rapidly absorbed from the GI tract, with peak blood levels at 1 hour. At doses > 30 mg/m² 
absorption decreases significantly. Even at low doses absorption may be very erratic, varying between 
23% and 95%. The elimination of MTX from the CSF after an intrathecal dose is characterized by a 
biphasic curve with half-lives of 4.5 and 14 hours. After intrathecal administration of 12 mg/m², the lumbar 
concentration of MTX is ~100 times higher than in plasma. (Ventricular concentration is ~ 10% of lumbar 
concentration). MTX is excreted primarily by the kidneys via glomerular filtration and active secretion into 
the proximal tubules. Renal clearance usually equals or exceeds creatinine clearance. Small amounts are 
excreted in the feces. There is significant entero-hepatic circulation of MTX. The distribution of MTX into 
third-space fluid collections, such as pleural effusions and ascitic fluid, can substantially alter MTX 
pharmacokinetics. The slow release of accumulated MTX from these third spaces over time prolongs the 
terminal half-life of the drug, leading to potentially increased clinical toxicity.

Leucovorin Calcium (LCV, Wellcovorin®, citrovorum factor, folinic acid) NSC #003590 
 
6.5.1 
Source and Pharmacology:  
Leucovorin is a mixture of the diastereoisomers of the 5-formyl derivative of tetrahydrofolic acid (THF). 
The biologically active compound of the mixture is the (-)- l-isomer, known as Citrovorum factor or (-)- 
folinic acid. Leucovorin does not require reduction by the enzyme dihydrofolate reductase in order to 
participate in reactions utilizing folates as a source of ―one-carbon‖ moieties. Administration of 
leucovorin can counteract the therapeutic and toxic effects of folic acid antagonists such as methotrexate, 
which act by inhibiting dihydrofolate reductase. In contrast, leucovorin can enhance the therapeutic and 
toxic effects of fluoropyrimidines used in cancer therapy, such as 5-fluorouracil. Leucovorin is readily 
converted to another reduced folate, 5,10-methylenetetrahydrofolate, which acts to stabilize the binding of 
fluorodeoxyuridylic acid (an active metabolite of 5-FU) to thymidylate synthase and thereby enhances the 
inhibition of this enzyme. Peak serum levels of 5-methyl THF (an active metabolite) were reached at 
approximately 1.3-1.5 hours (IV/IM) and 2.3 hours for the oral form. The terminal half-life of total reduced 
folates was approximately 6.2 hours. Following oral administration, leucovorin is rapidly absorbed and 
expands the serum pool of reduced folates. At a dose of 25 mg, almost 100% of the l-isomer (the 
biologically active form) but only 20% of the d-isomer is absorbed. Oral absorption of leucovorin is 
saturable at doses above 25 mg. The apparent bioavailability of leucovorin was 97% for 25 mg, 75% for 
50 mg, and 37% for 100 mg doses. Both oral and parenteral leucovorin raise the CSF folate levels.

6.5.4 Guidelines for Administration:  
See Treatment and Dose Modifications sections of the protocol. 
 
 
Injection: Because of the calcium content of the leucovorin solution, no more than 160 mg of 
leucovorin should be injected intravenously per minute (16 mL of a 10 mg/mL solution per 
minute). IV leucovorin and sodium bicarbonate are incompatible.  
 
 
Oral: Oral leucovorin should be spaced evenly (e.g., every six hours) throughout the day and may 
be taken without regard to meals. Doses > 25 mg should be given IV due to the saturation of 
absorption. Leucovorin should not be administered < 24 hours after intrathecal injections which 
contain methotrexate unless there are special circumstances.  
 
Supplier: Commercially available from various manufacturers. See package insertfor further information. 
 
 
6.6 
IT Cytarabine 
 
6.6.1 Source and Pharmacology:  
Cytarabine appears to act through the inhibition of DNA polymerase. A limited, but significant, 
incorporation of cytarabine into both DNA and RNA has also been reported. It exhibits cell phase 
specificity, primarily killing cells undergoing DNA synthesis (S-phase) and under certain conditions 
blocking the progression of cells from the G1 phase to the S-phase. Cytarabine is metabolized by 
deoxycytidine kinase and other nucleotide kinases to the nucleotide triphosphate (Ara-CTP), an effective 
inhibitor of DNA polymerase. Ara-CTP is inactivated by a pyrimidine nucleoside deaminase, which 
converts it to the nontoxic uracil derivative (Ara-U). It appears that the balance of kinase and 
deaminaselevels may be an important factor in determining sensitivity or resistance of the cell to 
cytarabine. It has an initial distributive phase t½ of about 10 minutes, with a secondary elimination phase 
t½ of about 1 to 3 hours. Peak levels after intramuscular or subcutaneous administration of cytarabine 
occur about 20 to 60 minutes after injection and are lower than IV administration. Intrathecally 
administered doses are metabolized and eliminated more slowly with a t½ of about 2 hours.

6.7.1 
Source and Pharmacology:  
The intrathecal route of administration of a drug produces more consistent CSF drug concentrations at 
relatively smaller doses because of the volume difference between the CSF and blood compartments 
(140 mL vs. 3500 mL in an adult). (The CSF volume of children after the first 3 years is equivalent to that of 
an adult). Drug half-lives are longer as well because clearance is related to flow rather than metabolism or 
protein binding. Intrathecal methotrexate has a biphasic elimination curve from the CSF with a t½ of 4.5 and 
14 hours respectively. Following IT injection of cytarabine the elimination of the drug from the CSF is 
biphasic with a t½ of 1 and 3.4 hours respectively which is 8-fold longer than the clearance from plasma. The 
elimination of hydrocortisone is similarly prolonged.

7.0   REQUIRED OBSERVATIONS/MATERIAL AND DATA TO BE ACCESSIONED 
 
 
All protocol-specified hematology, blood chemistries, and bone marrow aspirations and/or biopsies are to 
be performed under the auspices of the local laboratory at each investigational site. Additional 
assessments may be obtained as needed for good patient care. 
 
7.1 
Required Clinical, Laboratory and Disease Evaluation 
 
Laboratory values used to assess eligibility (see Section 3.0) must be no older than seven (7) days at the 
time of enrollment.   
 
Imaging studies must be obtained within 14 days prior to enrollment (repeat the tumor imaging if 
necessary). Chest x-ray for eligibility, per section 3.3.6.5, may also be obtained within 14 days of 
enrollment.  The bone marrow aspirate (and/or biopsy) must be obtained within 14 days prior to the start 
of protocol therapy. Lumbar puncture must be done within 7 days prior to the start of protocol therapy or 
on day 1 of therapy.  
 
During the courses of therapy, any abnormal laboratory tests must be re-checked by day 36 to assess 
resolution. 
 
Patients who are removed from protocol therapy during course 1 should continue to have the required 
observations in Section 7.1 until the originally planned end of the course or until all adverse events have 
resolved, whichever happens LATER. The only exception is with documentation of the patient’s 
withdrawal of consent.

Following discontinuation of the study drug, the patient will be treated in accordance with the 
investigator's best clinical judgment. If a patient discontinues from the study due to an adverse event 
considered possibly or probably related to study drug, a Follow-up Visit must be conducted no later than 
30 days after the last dose of anti-cancer therapy administered as part of this protocol. Safety 
assessments will be conducted at least every 30 days, until all toxicities resolve, return to baseline or 
become clinically satisfactory, stable, or are considered irreversible. 
 
Patients will be followed for life for any delayed toxicities related to protocol therapy, and secondary 
malignancies. Survival information, including disease status, alternative therapies, sites of relapse and 
the date and cause of death will be collected after the last study visit until the patient is considered off 
study.

Bone Marrow MRD (Required for leukemia patients)  
 
If a patient has <5% bone marrow blasts (morphologically) on their end of Course 1 and/or 2 bone 
marrow, and is not aplastic, bone marrow will be sent to determine minimal residual disease by 
immunoflow. These data will provide important correlative data regarding MRD and early response to 
combined therapy. If aplastic with subsequent non-blasts recovery MRD should be sent with the bone 
marrow that documents recovery 
 
Samples requested: 
Bone Marrow  
 
Course 1, Day 29 +/- 3 days if < 5% blasts by local morphology  
 
Course 2, Day 29 +/- 3 days if < 5% bone marrow blasts post

Bone Marrow Collection 
Procedure: 
 
 
Collect 6 mL for patients ≥12 kg and 3 mL for patients < 12 kg 
of marrow into a syringe and transfer the specimen 
immediately into a conical tube with 15 ml of RPMI/EDTA. If 
the shipping media tubes are unavailable, place the marrow 
into large purple EDTA tubes that are commonly used in all 
hospitals.  The viability would be enhanced if put into 
RPMI/EDTA for shipping. 
 
Mix sample well. Up to 5 ml of marrow can be placed in one 15 
cc tube with RPMI/EDTA.   
 
Use multiple syringes and tubes as needed. Reposition marrow 
aspirate needle as least once during procedure to ensure the 
maximum quality of marrow. 
 
Specimen Labeling: 
Each tube must be labeled with the study ID number and TACL ID 
along with the date and time the sample was obtained.  No personal 
identifying patient information should be included on the specimen or 
transmittal form.

8.2 
Bone Marrow Correlative Biology Studies (Optional) 
 
Participation in the collection of these specimens is encouraged, but is voluntary, and patients may 
still participate in the therapeutic part study if they decline correlative biology studies. Institutions are 
encouraged to talk to their patients about participation. 
 
The following description of studies applies for the bone marrow and PBMC correlative studies described 
in Section 8.2 and Section 8.3 of the protocol. 
 
1. Evaluating effect of temsirolimus on mTOR pathway proteins 
The effects of temsirolimus upon ALL cells will be assessed by comparing expression of a number of 
key mTOR signaling proteins before and after initiating treatment. The changes in activation 
(phosphorylation) of the PI3K/mTOR pathway and other signaling proteins will be determined by 
leukemia cell-specific phosphoflow cytometry analyses +/- immunoblotting using published 
techniques..5, 6, 21 Baseline and subsequent PBMC samples will be collected at designated timepoints 
from patients regardless with any level of peripheral ALL blasts present at time of study entry.  
 
2. Investigating the impact of temsirolimus on proteins involved in resistance to chemotherapy. 
ALL blasts from blood and/or bone marrow will also be studied to assess changes in proteins involved 
in chemotherapy resistance. Proteins will be studied by immunoblot using published techniques and 
may include markers of methotrexate resistance (DHFR, Rb, and cyclin D1) and corticosteroid 
resistance (MCL1, RIP-1, CYLD, beclin-1, BRG1, and GSK3).5, 6, 13  21, 42 If necessary, samples will be 
flow sorted to enrich for ALL blasts. These studies will be performed pre-study, once between Day 3-
5 if peripheral blast count is ≥2500/mm3. If peripheral blasts count is not ≥ 2500/mm3, pre-study bone 
marrow will be used and compared to end of cycle 1 bone marrow.  
 
3. Investigating the impact of temsirolimus on membrane transporters. mTOR inhibitors, including 
temsirolimus, have the potential to inhibit a number of membrane transporters, including ABCG2 
(BCRP), Pgp, and MRP. Inhibition of these transporters may affect metabolism of other medications

and chemotherapeutic agents.43,44 ABCG2, Pgp, and MRP levels, will be measured in ALL blasts by 
flow cytometry, using published techniques.44 These studies will be performed on peripheral blood if 
peripheral blasts count is ≥2500/mm3 or bone marrow if less than 2500/mm3 with time points as 
described in resistance to chemotherapy experiments. See section 8.3 for further details on 
peripheral blood biology studies. These studies will only be performed on samples that are shipped 
fresh. 
 
4. Studies of ALL blasts treated with temsirolimus alone and in combination with cytotoxics in 
pre-clinical models of ALL 
ALL blasts from pre-treatment samples will be injected into xenograft models of ALL for expansion of 
blast numbers and to assess in vivo response to treatment with temsirolimus with and without 
cytotoxic agents, using published techniques.6, 18  
 
If cells (peripheral blood and/or bone marrow) are limited, priority will be the following order: (1) MRD 
assessment, (2) studies assessing changes in mTOR pathway; (3) xenograft experiments, (4) studies 
assessing proteins involved in chemotherapy resistance, and (5). studies assessing impact of 
temsirolimus on membrane transporters

Pregnancy during research participation: Information may only be collected on a 
research patient who becomes pregnant and is ≥ 18, a partner of a research participant 
who becomes pregnant and is ≥18 at the time of the pregnancy and/or the newborn infant 
provided that the proper  IRB-approved, consent forms and data collection forms contain 
provisions for collection of information on the pregnancy and outcome.  
 
Incidents of exposure during pregnancy should be reported as an SAE using the IIR 
Serious Adverse Event Report Form (and Reportable Event Fax Cover Sheet) along with 
the Exposure During Pregnancy Supplemental Form. A second Exposure During 
Pregnancy Supplemental Form should be submitted to report the outcome of the 
pregnancy. 
 
 
If the outcome of the pregnancy meets any of the criteria for seriousness, report it 
to Pfizer as an SAE if permitted by your IRB on this trial. Otherwise a separate consent 
will need to be obtained to report pregnancy outcome data.  
 
Examples of pregnancy outcomes that are SAEs: 
- Spontaneous abortion (includes miscarriage and missed abortion) 
- Stillbirth 
- Congenital anomaly (including in an aborted fetus, a stillborn infant, or neonate that dies 
shortly after birth) 
- Neonatal death (within 1 month of birth) should be reported, without 
regard to causality 
- Any infant death that is assessed as possibly related to the in utero exposure to 
temsirolimus should be reported as an SAE

9.4  
Reproductive Risks  
 
In male animal studies, fertility was decreased or absent. These effects on male fertility were 
accompanied by testicular tubular degeneration, decreased sperm concentration and motility, decreased 
reproductive organ weights, and prostate atrophy. In female animal fertility studies, there were decreased 
number of corpora lutea and increased incidences of pre- and post-implantation loss resulting in 
decreased number of live fetuses, and decreased fetal weights. 
 
In developmental animal studies, there were increased embryo/fetal mortality and decreased fetal growth 
(decreased fetal weight and delayed skeletal ossification). Also there was an increased incidence of 
intestinal protrusion through the abdomen.  
 
However, there are no adequate and well-controlled studies in pregnant women using temsirolimus nor is 
there any information available for labor and delivery. Additionally, many drugs are excreted in human 
milk but lactation studies of intravenous Temsirolimus have not been conducted and the effects of 
temsirolimus excretion in human milk have not been evaluated. 
 
The potential risk for humans is unknown. 
 
10.0 
STATISTICAL CONSIDERATIONS 
  
10.1 
Statistical Considerations for Dose Escalation Criteria 
  
The primary endpoint for dose escalation is the occurrence of a dose-limiting toxicity (DLT). A standard 3+3 
patient cohort escalation design, as described below, will be used based on the toxicity experienced in the 
first course of treatment: 
 
1. Three patients are entered at the first dose level 
2. If 0/3 experiences DLT at a given dose level, then the dose is escalated to the next higher level, if a 
higher dose level exists, and three patients are enrolled.  If a higher dose level does not exists, up 
to three more patients are accrued at the same dose level. 
3. If 1/3 experiences DLT at current dose, then up to three more patients are accrued at the same 
dose level. 
4. If 2 or more DLTs are observed in a three-patient or six-patient cohort at a given dose level, then 
the MTD has been exceeded, dose escalation will be stopped, and up to three additional patients 
will be enrolled at the next lower dose level, if a lower dose level exists (unless six patients have 
already been treated at that prior dose). 
 
10.1.1 Maximum Tolerated Dose (MTD)/Highest Tested Dose (HTD) 
The MTD is the highest dose level tested at which 0/6 or 1/6 patients experience DLT with 
at least 2/3 or 2/6 patients encountering DLT at the next higher dose.  If the highest 
specified dose level (Dose Level 4) in this study is reached with 0/6 or 1/6 patients 
experiencing DLT, i.e., the MTD has not been reached, this dose level will be referred to as 
the Highest Tested Dose (HTD).  If at least 2/3 or 2/6 patients encountering DLT at the 
lowest dose, then no MTD exists. See also section 10.2.   
 
10.1.2   Definition of a Patient Evaluable for Toxicity  
Any patient who receives at least one dose of temsirolimus and experiences DLT at any 
time during protocol therapy is considered evaluable for Adverse Effects. Patients are 
evaluable for toxicity assessment if they terminate treatment for toxicity or intolerability, or 
they experience a dose limiting toxicity, or they receive 85% of the required dose of and 
other agents without dose limiting toxicity during the first course of therapy.  Patients who 
do not satisfy one of these conditions are not evaluable for toxicity and will be replaced.  
 
10.1.3 Definition of a Patient Evaluable for Response  
A patient enrolled on the trial who receives any prescribed therapy (day 1 and later) is 
considered evaluable for response.

10.2 
Patient Accrual and Study Duration 
The proposed study will accrue a minimum of 2 and maximum of 24 patients. Estimated accrual 
is 1-2 patients a month. This is expected to take 12-36 months. Allowing for time to evaluate 
patients for DLT, slow initial accrual rate, and opening of other relapsed ALL studies, it is 
expected that this study will be open to accrual for 2-3 years. 
 
10.3 
Interim Monitoring of Toxic Death  
The occurrence of toxic death (TD) at any time will be a primary endpoint for safety monitoring. 
When a patient expires while undergoing treatment, within 30 days of receiving protocol therapy, 
or during follow-up where the death is directly attributed to toxicity experienced on the protocol, 
the study committee and statistician will be notified to review the event. No formal statistical rule 
will be employed.   Rather, if the crude proportion of patients experiencing a toxic death exceed 
5% at any time, the cause and circumstances of these deaths will be reviewed with the study 
committee and with the Data and Safety Monitoring Committee to determine whether 
modifications to or termination of the study is warranted. 
 
 
10.4 
Inclusion of Women and Minorities 
The study is open to all participants regardless of gender or ethnicity.  Review of accrual to past 
studies of new agents demonstrates the accrual of both genders and all NIH-identified ethnicities to 
such studies. The small number of patients entered into this trial will obviate any analysis of 
variation in response rate with gender or ethnicity. 
 
10.5 
Correlative Studies and Response Analysis 
A descriptive analysis of the pharmacodynamic (PD) effects of temsirolimus will be performed to 
assess inhibition of mTOR and downstream signaling in patients’ lymphoblasts.  The PD data will 
be summarized with simple summary statistics, including means, medians, ranges, and standard 
deviations (if numbers and distribution permit).   
 
While the primary aim of this study is to evaluate the toxicity of temsirolimus, patients will have 
disease evaluations performed at end of therapy.  Disease response will be assessed according 
to RECIST criteria for patients with lymphoma, and will be reported descriptively. 
 
All these analyses will be descriptive and exploratory and hypotheses generating in nature.

RESPONSE CRITERIA 
 
11.1 
Bone Marrow Status Definitions 
 
 
M1 Marrow 
Less than 5% blasts in a bone marrow aspirate or biopsy if aspirate not available. 
 
M2 Marrow 
5-25% blasts in a bone marrow aspirate or biopsy if aspirate not available.  
 
M3 Marrow 
Greater than 25% blasts in a bone marrow aspirate or biopsy if aspirate not available. 
 
 
11.2 
Response Criteria for Patients with Leukemia  
 
11.2.1 Complete Remission (CR)  
Attainment of M1 bone marrow with no evidence of circulating blasts or extramedullary 
disease and with recovery of peripheral counts (ANC ≥ 500/µL and PLT count ≥ 50,000 
µL). Qualifying marrow and peripheral counts should be performed within 1 week of each 
other. 
 
 
11.2.2 Complete Remission with Incomplete Blood Count Recovery (CRi)  
Attainment of M1 bone marrow with no evidence of circulating blasts or extramedullary 
disease, but with insufficient recovery of absolute neutrophil count (ANC < 500/µL) or 
platelets (< 50,000/ µL). 
 
11.2.3  Minimal Residual Disease negative subset of CR/CRi 
The attainment of a bone marrow with MRD < 0.01% blasts while meeting criteria for CR 
or CRi. 
 
11.2.4 Partial Remission (PR) 
Complete disappearance of circulating blasts and achievement of M2 marrow status if M3 
originally without new sites of extramedullary disease, and with recovery of absolute 
neutrophil counts (ANC ≥ 500/µL). Complete response in the marrow without resolution of 
extramedullary sites is a PR.  
 
11.2.5 Stable Disease (SD) 
Patient does not satisfy the criteria for PD, or has recovery of ANC ≥ 500/µL and fails to 
qualify for CR, CRi, or PR.  
 
11.2.6 Progressive Disease (PD) 
An increase of at least 25% in the absolute number of bone marrow leukemic cells 
morphologically, development of new sites of extramedullary disease, or other laboratory 
or clinical evidence of PD, with or without recovery of ANC or platelets. Patients with 
MRD-only level disease (< 5% blasts) at study entry who develop ≥ 10% disease 
morphologically will be considered to have progressive disease.

Any patient who dies prior to receiving subsequent therapy.   
 
11.2.8 Not evaluable (NE) 
Patient does not satisfy the criterion for PD or ID, and either did not have a marrow 
evaluation, had inadequate marrow cell count, or had insufficient recovery of ANC to be 
classified as CR, CRi, PR, or SD.

CONFIDENTIAL 
 
 
TACL Internal Distribution Only 
62
 
 
11.3.1  CNS Status Definitions 
 
CNS 1: In cerebral spinal fluid (CSF), absence of blasts on cytospin preparation, 
regardless of the number of white blood cells (WBCs). 
 
CNS 2: In CSF, presence < 5/μL WBCs and cytospin positive for blasts, or ≥ 5 /μL WBCs 
but negative by Steinherz/Bleyer algorithm: 
 
CNS 2a: < 10/μL RBCs; < 5/μL WBCs and cytospin positive for blasts; 
CNS 2b: ≥ 10/μL RBCs; < 5/μL WBCs and cytospin positive for blasts; and 
CNS 2c: ≥ 10/μL RBCs; ≥ 5/μL WBCs and cytospin positive for blasts but negative by 
Steinherz/Bleyer algorithm (see below) 
 
CNS 3: In CSF, presence of ≥ 5/μL WBCs and cytospin positive for blasts and/or clinical 
signs of CNS leukemia: 
 
CNS 3a: < 10/μL RBCs; ≥ 5/μL WBCs and cytospin positive for blasts; 
CNS 3b: ≥ 10/μL RBCs, ≥ 5/μL WBCs and positive by Steinherz/Bleyer algorithm (see 
below) 
CNS 3c: Clinical signs of CNS leukemia/lymphoma (such as facial nerve palsy, brain/eye 
involvement or hypothalamic syndrome). 
  
METHOD OF EVALUATING INITIAL TRAUMATIC LUMBAR PUNCTURES: 
If the patient has leukemic cells in the peripheral blood and the lumbar puncture is 
traumatic and contains ≥ 5 WBC/µL and blasts, the following Steinherz/Bleyer algorithm 
should be used 
 
CSF WBC > 2X  Blood WBC 
CSF RBC           Blood RBC 
 
A patient with CSF WBC ≥ 5/µL blasts, whose CSF WBC/RBC is 2X greater than the 
blood WBC/RBC ratio, has CNS disease at diagnosis.  
 
Example: CSF WBC = 60/µL; CSF RBC = 1500/µL; blood WBC =46000/µL;  
blood RBC = 3.0 X 106/µL: 
 
CSF calculation     Blood calculation          
  60   = 0.04            46000   = 0.015 x 2 = .03 
1500 
            3.0 X 106 
 
Therefore this patient has CNS disease because 0.04 > 0.03 
 
11.4   
Response Criteria for Patients with Lymphoma  
 
Response and progression will be evaluated in this study using the revised Response Evaluation 
Criteria in Solid Tumors (RECIST) guideline (version 1.1).45 Key points are that 5 target lesions 
are identified and that changes in the largest diameter (unidimensional measurement) of the 
tumor lesions but the shortest diameter of malignant lymph nodes are used in the RECIST v 1.1 
criteria. 
 
11.4.1 Definitions 
 
11.4.1.2 
Evaluable for objective response: Patients who exhibit objective disease 
progression prior to the end of cycle 1 will be considered evaluable for 
response. For all other patients, only those patients who have 
measurable disease present at baseline, have received at least one 


 
 
 
Protocol  Amendment #2 
1-18-2018

TACL Internal Distribution Only 
63
cycle of therapy, and have had their disease re-evaluated will be 
considered evaluable for response.  
 
11.4.1.2 
Evaluable Non-Target Disease Response: Patients who have lesions 
present at baseline that are evaluable but do not meet the definitions of 
measurable disease, have received at least one cycle of therapy, and 
have had their disease re-evaluated will be considered evaluable for 
non-target disease.  The response assessment is based on the 
presence, absence, or unequivocal progression of the lesions.  
 
11.4.2 Disease Parameters 
 
 
11.4.2.1 
Measurable disease: Measurable lesions are defined as those that can 
be accurately measured in at least one dimension (longest diameter to 
be recorded) as >20 mm by chest x-ray, as >10 mm with CT scan, or 
>10 mm with calipers by clinical exam.  All tumor measurements must be 
recorded in millimeters (or decimal fractions of centimeters). 
 
Note:  Tumor lesions that are situated in a previously irradiated area 
might or might not be considered measurable.  If the investigator 
thinks it appropriate to include them, the conditions under which 
such lesions should be considered must be defined in the 
protocol. 
 
11.4.2.2 
Malignant lymph nodes: To be considered pathologically enlarged and 
measurable, a lymph node must be >15 mm in short axis when assessed 
by CT scan (CT scan slice thickness no greater than 5 mm).  At baseline 
and in follow-up, only the short axis will be measured and followed. 
 
11.4.2.3 
Non-measurable disease: All other lesions (or sites of disease), including 
small lesions (longest diameter <10 mm or pathological lymph nodes 
with ≥ 10 to <15 mm short axis), are considered non-measurable 
disease. 
 
Bone 
lesions, 
leptomeningeal 
disease, 
ascites, 
pleural/pericardial effusions, lymphangitis cutis/pulmonitis, inflammatory 
breast disease, and abdominal masses (not followed by CT or MRI), are 
considered as non-measurable. 
 
Note:  Cystic lesions that meet the criteria for radiographically defined 
simple cysts should not be considered as malignant lesions 
(neither measurable nor non-measurable) since they are, by 
definition, simple cysts. ‘Cystic lesions’ thought to represent 
cystic metastases can be considered as measurable lesions, if 
they meet the definition of measurability described above. 
However, if non-cystic lesions are present in the same patient, 
these are preferred for selection as target lesions. 
 
11.4.2.4 
Target lesions: All measurable lesions up to a maximum of 2 lesions per 
organ and 5 lesions in total, representative of all involved organs, should 
be identified as target lesions and recorded and measured at baseline.  
Target lesions should be selected on the basis of their size (lesions with 
the longest diameter), be representative of all involved organs, but in 
addition should be those that lend themselves to reproducible repeated 
measurements.  It may be the case that, on occasion, the largest lesion 
does not lend itself to reproducible measurement in which circumstance 
the next largest lesion that can be measured reproducibly should be 
selected.  A sum of the diameters (longest for non-nodal lesions, short 
axis for nodal lesions) for all target lesions will be calculated and 
reported as the baseline sum diameters.  If lymph nodes are to be 


 
 
 
Protocol  Amendment #2

TACL Internal Distribution Only 
64
included in the sum, then only the short axis is added into the sum.  The 
baseline sum diameters will be used as reference to further characterize 
any objective tumor regression in the measurable dimension of the 
disease. 
 
11.4.2.5 
Non-target lesions: All other lesions (or sites of disease) including any 
measurable lesions over and above the 5 target lesions should be 
identified as non-target lesions and should also be recorded at baseline.  
Measurements of these lesions are not required, but the presence, 
absence, or in rare cases unequivocal progression of each should be 
noted throughout follow-up.  
 
11.4.3 Methods for Evaluation of Measurable Disease 
 
All measurements should be taken and recorded in metric notation using a ruler or     
calipers.  
 
The same method of assessment and the same technique should be used to characterize 
each identified and reported lesion at baseline and during follow-up. Imaging-based 
evaluation is preferred to evaluation by clinical examination unless the lesion(s) being 
followed cannot be imaged but are assessable by clinical exam. 
 
11.4.3.1 
Clinical lesions:  Clinical lesions will only be considered measurable 
when they are superficial (e.g., skin nodules and palpable lymph nodes) 
and 10 mm diameter as assessed using calipers (e.g., skin nodules).  In 
the case of skin lesions, documentation by color photography, including 
a ruler to estimate the size of the lesion, is recommended.  
 
11.4.3.2 
Chest x-ray:  Lesions on chest x-ray are acceptable as measurable 
lesions when they are clearly defined and surrounded by aerated lung.  
However, CT is preferable.  
 
11.4.3.3 
Conventional CT and MRI:  This guideline has defined measurability of 
lesions on CT scan based on the assumption that CT slice thickness is 5 
mm or less.  If CT scans have slice thickness greater than 5 mm, the 
minimum size for a measurable lesion should be twice the slice 
thickness.  MRI is also acceptable in certain situations (e.g. for body 
scans). Ideally, the same type of scanner should be used and the image 
acquisition protocol should be followed as closely as possible to prior 
scans.  
 
11.4.3.4 
PET-CT:  At present, the low dose or attenuation correction CT portion of 
a combined PET-CT is not always of optimal diagnostic CT quality for 
use with RECIST measurements.  However, if the site can document that 
the CT performed as part of a PET-CT is of identical diagnostic quality to 
a diagnostic CT (with IV and oral contrast), then the CT portion of the 
PET-CT can be used for RECIST measurements and can be used 
interchangeably with conventional CT in accurately measuring cancer 
lesions over time.  Note, however, that the PET portion of the CT 
introduces additional data which may bias an investigator if it is not 
routinely or serially performed.   
 
11.4.3.5 
Tumor markers: Tumor markers alone cannot be used to assess 
response.  If markers are initially above the upper normal limit, they must 
normalize for a patient to be considered in complete clinical response.  
 
11.4.3.6 
Cytology, Histology: These techniques can be used to differentiate 
between partial responses (PR) and complete responses (CR) in rare 


 
 
 
Protocol  Amendment #2 
1-18-2018 
 
CONFIDENTIAL 
 
 
TACL Internal Distribution Only 
65
cases (e.g., residual lesions in tumor types, such as germ cell tumors, 
where known residual benign tumors can remain). 
 
 
Cytology should be obtained if an effusion appears or worsens during 
treatment when the measurable tumor has met criteria for response or 
stable disease. 
 
11.4.3.7 
FDG-PET: While FDG-PET response assessments need additional 
study, it is sometimes reasonable to incorporate the use of FDG-PET 
scanning to complement CT scanning in assessment of progression 
(particularly possible 'new' disease).  New lesions on the basis of FDG-
PET imaging can be identified according to the following algorithm:  
 
a. Negative FDG-PET at baseline, with a positive FDG-PET at follow-
up is a sign of PD based on a new lesion. 
b. No FDG-PET at baseline and a positive FDG-PET at follow-up:  If 
the positive FDG-PET at follow-up corresponds to a new site of 
disease confirmed by CT, this is PD.  If the positive FDG-PET at 
follow-up is not confirmed as a new site of disease on CT, additional 
follow-up CT scans are needed to determine if there is truly 
progression occurring at that site (if so, the date of PD will be the 
date of the initial abnormal FDG-PET scan).  If the positive FDG-
PET at follow-up corresponds to a pre-existing site of disease on 
CT that is not progressing on the basis of the anatomic images, this 
is not PD. 
 
 Note:  A ‘positive’ FDG-PET scan lesion means one that is FDG avid 
with an uptake greater than twice that of the surrounding tissue 
on the attenuation corrected image. 
 
 
11.4.4 Evaluation of Target Lesions 
 
11.4.4.1  
Complete Response (CR): Disappearance of all target and non-target 
lesions. Any pathological lymph nodes (whether target or non-target) 
must have reduction in short axis to <10 mm. If immunocytology is 
available, no disease must be detected by that methodology.   
 
11.4.4.2    
Partial Response (PR): At least a 30% decrease in the sum of the 
diameters of target lesions, taking as reference the baseline sum 
diameters 
 
11.4.4.3   
Progressive Disease (PD): At least a 20% increase in the sum of the  
diameters of target lesions, taking as reference the smallest sum on 
study (this includes the baseline sum if that is the smallest on study).  In 
addition to the relative increase of 20%, the sum must also demonstrate 
an absolute increase of at least 5 mm.  (Note:  the appearance of one or 
more new lesions is also considered progressions). Note: in presence of 
SD or PR in target disease but unequivocal progression in non-target or 
non-measurable disease, the patient has PD if there is an overall level of 
substantial worsening in non-target disease such that the overall tumor 
burden has increased sufficiently to merit discontinuation of therapy 
 
11.4.4.4  
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor 
sufficient increase to qualify for PD, taking as reference the smallest sum 
diameters while on study

11.4.5.1   
Complete Response (CR): Disappearance of all non-target lesions and 
normalization of tumor marker level.  All lymph nodes must be non-
pathological in size (<10 mm short axis) 
 
Note:  If tumor markers are initially above the upper normal limit, they 
must normalize for a patient to be considered in complete clinical 
response. 
 
11.4.5.2   
Non-CR/Non-PD: Persistence of one or more non-target lesion(s) and/or 
maintenance of tumor marker level above the normal limits 
 
11.4.5.3  
Progressive Disease (PD): Appearance of one or more new lesions 
and/or 
unequivocal 
progression 
of 
existing 
non-target 
lesions.  
Unequivocal progression should not normally trump target lesion status.  
It must be representative of overall disease status change, not a single 
lesion increase.

Overall Best Response Assessment 
 Each patient will be classified according to his “best response” for the 
purposes of analysis of treatment effect.  Best response is determined as 
outlined in Section 11.5 from a sequence of overall response 
assessments. 
 
11.4.6 Response Criteria for Patients with Lymphoma and Evaluable (but not Measurable) 
Disease 
 
11.4.6.1 
Evaluable Disease 
The presence of at least one lesion, with no lesion that can be accurately 
measured in at least one dimension.  Such lesions may be evaluable by 
nuclear medicine techniques, immunocytochemistry techniques, tumor 
markers or other reliable measures.  
 
11.4.6.2 
Complete Response 
Disappearance of all evaluable disease. 
 
11.4.6.3 
Partial Response 
Partial responses cannot be determined in patients with evaluable 
disease 
 
11.4.6.4 
Stable Disease  
That which does not qualify as Complete Response (CR), Partial 
Response (PR), or Progressive Disease.

The best overall response is the best response recorded from the start of the 
treatment until disease progression/recurrence (taking as reference for 
progressive disease the smallest measurements recorded since the treatment 
started).  The patient's best response assignment will depend on the 
achievement of both measurement and confirmation criteria.

*** In exceptional circumstances, unequivocal progression in non-target lesions 
may be accepted as disease progression. 
Note: 
Patients with a global deterioration of health status requiring 
discontinuation of treatment without objective evidence of disease 
progression at that time should be reported as “symptomatic 
deterioration.”  Every effort should be made to document the objective 
progression even after discontinuation of treatment.

11.5.2 Duration of Response 
 
11.5.2.1 
Duration of overall response:  The duration of overall response is measured   
 
from the time measurement criteria are met for CR or PR (whichever is first  
 
 
recorded) until the first date that recurrent or progressive disease is 
 
objectively documented (taking as reference for progressive disease the  
 
 
smallest measurements recorded since the treatment started). 
 
 
The duration of overall CR is measured from the time measurement criteria  
 
 
are first met for CR until the first date that progressive disease is objectively   
 
 
documented. 
 
11.5.2.2    Duration of stable disease:  Stable disease is measured from the start of the   
treatment until the criteria for progression are met, taking as reference the 
smallest measurements recorded since the treatment started, including the 
baseline measurements.

ADVERSE EVENT REPORTING REQUIREMENTS  
 
12.1 
Definitions 
 
Adverse Event: An adverse event means any untoward medical occurrence associated with the use of a 
drug in humans, whether or not considered drug related. 
 
Suspected Adverse Reaction (SAR): Any adverse event for which there is a reasonable possibility that 
the drug caused the adverse event.  Reasonable possibility means there is evidence to suggest a causal 
relationship between the drug and the adverse event. 
 
Unexpected Adverse Event or Unexpected Suspected Adverse Reaction: An adverse event or 
suspected adverse reaction is considered “unexpected” if it is not listed in the investigator brochure or is 
not listed at the specificity or severity that has been observed; or, if an investigator brochure is not 
available, is not consistent with the risk information described in the general investigational plan. 
 
Serious Adverse Events (SAE) or Serious Suspected Adverse Reactions (SSAR): An adverse event 
or suspected adverse reaction is considered serious if, in the view of either the investigator or sponsor, it 
results in any of the following outcomes: 
 
Death of Patient 
An event that results in the death of a patient. 
Life-Threatening 
An event that, in the opinion of the investigator, would have resulted in 
immediate fatality if medical intervention had not been taken.  This does not 
include an event that would have been fatal if it had occurred in a more severe 
form. 
Hospitalization 
An event that results in an admission to the hospital for any length of time.  
This does not include an emergency room visit or admission to an outpatient 
facility. 
Prolongation of 
Hospitalization 
An event that occurs while the study patient is hospitalized and prolongs the 
patient’s hospital stay. 
Congenital 
Anomaly 
An anomaly detected at or after birth, or any anomaly that results in fetal loss. 
Persistent or 
Significant 
Disability/ 
Incapacity 
An event that results in a condition that substantially interferes with the 
activities of daily living of a study patient.  Disability is not intended to include 
experiences of relatively minor medical significance such as headache, 
nausea, vomiting, diarrhea, influenza, or accidental trauma (e.g., sprained 
ankle). 
Important 
Medical Event 
Requiring 
Medical or 
Surgical 
Intervention to 
Prevent Serious 
Outcome 
An important medical event that may not be immediately life-threatening or 
result in death or hospitalization, but based on medical judgment may 
jeopardize the patient and may require medical or surgical intervention to 
prevent any of the outcomes listed above (i.e., death of patient, life-
threatening, hospitalization, prolongation of hospitalization, congenital 
anomaly, or persistent or significant disability/incapacity). Examples of such 
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. 
 
12.2 
Data Collection 
Adverse events and suspected adverse reactions will be collected and reported on the electronic CRFs 
beginning with the first dose of study therapy until 30 days following the last dose of study therapy. The 
investigator will evaluate all adverse events and suspected adverse reactions as to their severity and 
relationship to temsirolimus as well as the regimen as a whole. Serious adverse events and serious 
suspected adverse reactions will require expedited reporting to the TACL Operations Center as 
described below.

12.3 
Reporting Serious Adverse Events or Serious Suspected Adverse Reactions 
 
12.3.1 The following serious adverse events or serious suspected adverse reactions 
requires expedited reporting: 
 
 
All Grade 5 events regardless of causality. 
 
All Grade 4 events that are possibly, probably or definitely related to temsirolimus or 
the regimen as a whole.  Exclude reporting of hematologic toxicity as a serious 
adverse event unless the event meets the criteria of hematologic dose limiting toxicity 
per protocol section 4.5.2:  Bone marrow aplasia: > 42 days from Day 1 of therapy 
will be a DLT. Aplasia is defined as the failure to recover a peripheral ANC of ≥ 
500/mm3 and PLT ≥ 20,000/mm3 in the absence of persistent leukemia. 
 
 
All unexpected Grade 3 events that are possibly, probably or definitely related to 
temsirolimus or the regimen as a whole. 
 
Any reported pregnancy in a female study patient or partner of a male study patient 
 
12.3.2 Steps for Reporting 
 
Step 1: Identify the adverse event or suspected adverse reaction using the NCI 
Common Toxicity Criteria (CTC), version 4.03.    
 
The CTC provides descriptive terminology and a grading scale for each adverse event 
listed.  A copy of the CTC can be downloaded at  
http://evs.nci.nih.gov/ftp1/CTCAE/About.html.   
 
Step 2: Grade the event using the NCI CTCAE version 4.03. 
 
Step 3: Determine if the adverse event or suspected adverse reaction meets the 
criteria of being “serious”. 
 
 
Step 4: Determine the relationship of Temsirolimus and the regimen as a whole to 
the event 
The investigator will assess the causal relationship between the investigational product 
and the regimen as a whole and the adverse event.  The investigator will use his/her 
clinical expertise and judgment to select the attribution category below that best fits the 
circumstances of the AE. 
 
Related: There is a reasonable possibility that the drug/regimen caused the 
adverse event. Reasonable possibility means there is evidence to suggest a 
causal relationship between the drug and the adverse event. 
 
Unrelated: There is not a reasonable possibility that the drug/regimen caused 
the adverse event. There is not evidence to suggest a causal relationship 
between the drug and the adverse event. 
 
Step 5: Determine if the adverse event or suspected adverse reaction is 
“unexpected”.  
 
Step 6: Notify the TACL Operations Center by telephone or email 
 
The following information should be submitted within 24 hours of event notification by either 
phone 
, or Email TACL@chla.usc.edu

DATA AND SAFETY MONITORING 
 
13.1 
Data Submission 
All study data will be submitted via electronic data capture forms using the DataLabs/TACL Website.  
Please refer to the TACL web site (https://tacl.chla.usc.edu/tacl) for T2014-001 CRF Completion Guide or 
contact the TACL Operations Center at 
 if you need assistance. 
 
The following are required to be submitted to the Operations Center for all patients entered: 
Paper copy of following:  Roadmaps and Bone Marrow Reports (include both aspirate and biopsy 
reports). These forms are to be emailed or faxed to the TACL Operations Office at 877-904-2166 at the 
end of each course during which the bone marrows are done. 
 
13.2 
Weekly Safety Review 
The TACL Operations Center (TOC) conducts weekly (as needed) patient safety and review meetings 
with the protocol co-chairs, , research coordinators and other administrative TACL team members to 
review all data submitted, non-serious adverse events and other correspondence pertaining to patients.  
Serious adverse events will be immediately evaluated by the study team and determination regarding 
notification of participating sites will be made.  All serious adverse events will be sent to the CHLA IRB 
and DSMC if required.  Any interim results that would affect patient safety would be immediately 
communicated to all participating TACL sites. All correspondence with sites will be done via email, with all 
information also being posted on a member’s only section of the TACL website. 
 
13.3 
Data Safety and Monitoring Committee (DSMC) 
The TACL Operations Center utilizes the Children’s Hospital Los Angeles Hem/Onc Data Safety and 
Monitoring Committee. DSMC meetings will occur every 6 months. Every 6 months, a DSMC report for 
each protocol will be prepared by the study statistician and study PI detailing patient accrual, toxicities, 
deaths on study, current study status, responses (responses will be blinded until study completes 
accrual), summary of amendments to protocol/consent, lists of any publications from study, and plans for 
study in coming year.  Any publications from the study (abstract or manuscript) will be attached to the 
DSMC report.  After DSMC review, the DSMC will issue a confidential report for each study to the study 
PI and TACL Operations Center. 
 
Not more than eight weeks after the DSMC meeting, a DSMC public review report will also be created for 
each protocol after approval of the confidential report and resolution of any issues by the PI The public 
report will then be emailed to the participating sites for each study.  These can be filed at the IRB at each 
site if required per local IRB guidelines.

This study is being carried out by the Therapeutic Advances in Childhood Leukemia & Lymphoma (TACL) 
Consortium. TACL is a group of Universities and Children’s Hospitals that are working together to find 
treatments for children with leukemia and lymphoma. 
 
You are being asked to take part in this research study because your ALL or Non-Hodgkin’s Lymphoma 
has come back (relapsed).  
 
This is a phase I study of a drug called temsirolimus in combination with intensive cytotoxic chemotherapy 
consisting of cyclophosphamide and etoposide. Temsirolimus is considered experimental because it has 
not been proven to work in a situation like yours. We are using temsirolimus because it seems to work 
against cancer in cells and animals. We do not know if temsirolimus will work in people. Temsirolimus has 
been used in only a small number of adults and children and there is a lot that we do not know about it 
yet. This is called a Phase I study because the goal is to find the highest dose of temsirolimus that we can 
give safely in combination with intensive chemotherapy.  
 
Patients with multiply relapsed ALL have a significant risk of severe side effects and serious infections 
with intensive salvage therapy. In an attempt to provide your child the safest care possible it is highly 
recommended that your child receive their initial course as an inpatient and be started on preventative 
antibiotics and anti-fungal medications during their stay.

Why is this study being done? 
 
We are testing new experimental drug combinations such as the combination of temsirolimus, 
cyclophosphamide and etoposide in the hopes of finding a drug combination that may be effective against 
relapsed leukemia and non-hodgkin’s lymphoma. 
 
The goals of this study are: 
 
 
To find the highest safe dose of temsirolimus that can be given with intensive  chemotherapy 
without causing severe side effects; 
 
To learn what kind of side effects temsirolimus can cause; 
 
To learn more about the pharmacology (how your body handles the drug) of temsirolimus; 
 
To learn how temsirolimus affects specific molecules on leukemia and lymphoma cells;   
 
To determine whether temsirolimus, combined with intensive chemotherapy is a beneficial 
treatment for your tumor. 
 
How many people will take part in this study? 
 
It is expected that up to 24 children and young adults will take part in this study. 
 
What will happen if I take part in this research study? 
 
Before you begin the study… 
 
You will need to have the following exams, tests or procedures to find out if you can be in the study.  These 
exams, tests or procedures are part of your regular cancer care and may be done even if you do not join 
the study.  If you have had some of them recently, they may not need to be repeated. The results of these 
tests will be reviewed.  It is possible that after these tests are reviewed, you will not be able to take part in 
the study.  If you are not able to take part in the study, your doctor will discuss with you the reasons why. 
 
 
A medical history 
 
Physical exam with vital signs(blood pressure, heart rate, temperature, oxygen levels) 
 
Bone marrow test to check your cancer (see Tests on the Bone Marrow, below) 
 
Lumbar puncture to test the fluid in your spinal cord (see Lumbar Punctures, below) 
 
Blood tests to check your organ function, including liver and kidneys 
 
Tests to make sure you are not pregnant (if you are a female and old enough to become 
pregnant) 
 
Urine Test 
 
Imaging study (CT, MRI, PET/CT) to determine the extent of your cancer (if you have 
lymphoma) 
 
Echocardiogram (ECHO) which uses sound waves to test heart function 
 
 
Tests on the Bone Marrow 
Examinations of the bone marrow will be performed routinely and may be done at the discretion of your 
study doctor. You have already had many tests of your bone marrow for your previous treatment of ALL.  
Many children receive some form of sedation or anesthesia during this procedure. A small area over your 
hip bone on the back will be cleaned and numbed with lidocaine and/or with an anesthetic cream. 
Approximately 2-3 teaspoons of bone marrow will be withdrawn through a needle inserted into the bone. 
The test is painful, especially when the bone marrow is withdrawn.  There is also a small risk of bleeding 
or infection from this procedure.   
 
Lumbar Punctures (“L.P.s”, “spinal taps”)

You are familiar with spinal taps since they were done during your initial therapy for ALL. Whether you 
decide to participate or not on this study, additional spinal taps will need to be done to give medicines, 
which are necessary to prevent the leukemia from spreading to the spinal fluid. Many children receive 
some form of sedation or anesthesia during this procedure. Spinal taps are painful and may cause 
headaches. The skin at the site of needle insertion is usually numbed with an anesthetic cream or 
lidocaine before the procedure is performed. Approximately 1 teaspoon of spinal fluid will be withdrawn 
prior to injection of the medicine. 
 
During the study …  
 
If the exams, tests and procedures show that it is safe for you to be enrolled on the study, and you will be 
given temsirolimus by intravenous (IV) infusion on days 1 and 8. Cyclophosphamide and etoposide will be 
given by intravenous (IV) infusion on days 1-5. You will then recover from the combined therapy. A cycle 
last approximately 4 weeks and you may get up to 8 cycles as long as you have stable or improving 
cancer.  
 
We highly recommend you remain in the hospital from the time you start the therapy (or from Day 1) until 
blood work and your medical team determine it is safe for you to be sent home. We also highly 
recommend you are started on preventative antibiotics and anti-fungals while you are hospitalized. 
 
 
Various methods will be used to give drugs: 
 
IV – Drug is given using a needle or tubing inserted into a vein,  It can be given by IV push over 
several minutes or by infusion over minutes to hours 
 
IT – Drug used to treat the brain and spinal cord is given using a needle inserted into the spinal 
canal

Tests for Research Purposes 
We would also like to do some extra tests called biologic studies.  These tests will help us learn more about 
temsirolimus on leukemia cells and may help children who receive this drug in the future. The information 
learned would not change the way you are treated, and the results of these tests will not be returned to you. 
Some of these tests are required and others are optional.  Although these tests are very important part of 
how we will better learn to use this drug, it is your decision as to whether or not you agree to participate.  
. 
Bone Marrow Samples for MRD testing 
When bone marrow testing is being done as part of your standard evaluation(s) on Day 29 (or a later 
cycle if not quite in a complete remission on day 29), we would like to request an extra sample [6 mL 
(slightly more than 1 teaspoon) from patients greater than or equal to 12 kg (26.5 pounds), or 3 mL (less 
than 1 teaspoon) from patients less than 12 kg (26.5 pounds)] to be collected for minimal residual disease 
(MRD) testing. This type of testing is a more sensitive way to evaluate whether there are any leukemia 
cells present after therapy.  These bone marrow samples are required from all patients who had > 5% 
blasts in their bone marrow at study entry. 
 
Biology Studies using Bone Marrow Samples (Optional) 
When bone marrow testing is being done as part of your standard evaluation(s) before you begin therapy 
and on Day 29, we would like to request an extra sample [10 mL (about 2 teaspoons) from patients 
greater than or equal to 10 kg (22 pounds), 3-5 mL (about 1 teaspoon) from patients less than 10 kg (22 
pounds)] to be collected to evaluate the effect of temsirolimus on your cells in the bone marrow and if 
sample permits to grow your cancer in a mouse to further study the effect of temsirolimus and intensive 
reinduction chemotherapy on proteins in those cells. 
 
The tests may help us to better learn how this drug may work. Please indicate by initialing below whether 
you choose to participate in the biology studies. 
 
______/______ Yes, I agree to participate in the biology studies using bone marrow samples. 
 
______/______ No, I do not agree to participate in the biology studies using bone marrow samples. 
 
Biology Studies using Blood Samples (Optional) 
During the study, additional blood samples will be collected to evaluate the effect of temsirolimus and 
intensive reinduction chemotherapy in your blood. The blood samples are 5 mL (about 1 teaspoon) for 
patients greater than or equal to 10 kg (22 pounds), and 2 mL (about ½ teaspoon) from patients less than 
10 kg (22 pounds) and will be obtained prior to therapy, once between day 3 and 5  and at the end of cycle 
1 of therapy on Day 29.  This amount of blood is safe to draw even from small children. 
 
The tests may help us to better learn how this drug may work. Please indicate by initialing below whether 
you choose to participate in the biology studies. 
 
______/______ Yes, I agree to participate in the biology studies using blood samples. 
 
______/______ No, I do not agree to participate in the biology studies using blood samples. 
 
What are my responsibilities? 
 
 
During the study you will be asked to take all your chemotherapy drugs as prescribed. It is very 
important that you follow your doctor’s instructions regarding when and how to take your study 
medications.  Be sure to ask your study doctor or nurse if you have any questions about taking your 
study medications.   
 
 
If you experience any unusual side effects as explained by your study doctor, you should contact the 
study center immediately.  You should also contact your study doctor if you are hospitalized for any 
reason during the study or within 30 days after completion of therapy.

How long will I be in the study?   
 
If you have stable or responding disease you may receive up to 8 cycles of therapy for up to 1 year.  After 
completing the study therapy, your doctor will discuss with you the options for additional treatment.   
These options will vary depending on whether or not your leukemia or Non-Hodgkin Lymphoma 
responded to the therapy.  
 
After completing the treatment on this study we would like to continue to collect some medical information 
about how you are doing for as long as you are willing to let us.  We will collect information on how your 
ALL or Non-Hodgkin Lymphoma is doing, what kind of therapy you may be getting and if you have any 
long term side effects.   
 
 
Can I stop being in the study? 
 
Yes.  You can decide to stop at any time.  Your clinical care will not be affected by your decision to 
withdraw.  Tell your doctor if you are thinking about stopping or decide to stop.  He or she will tell you how 
to stop safely.   You will be asked to visit the hospital or clinic for some follow-up tests to make sure all the 
side effects you may have experienced have gone away. 
 
It is important to tell your doctor if you are thinking about stopping so any risks from the study treatment 
and chemotherapy drugs can be evaluated by your doctor.  Another reason to tell your doctor that you are 
thinking about stopping is to discuss what follow-up care and testing could be most helpful for you. 
 
Your doctor may stop you from taking part in this study at any time without your permission if he/she 
believes it is in your best interest; your tumor gets worse; if the side effects of temsirolimus or combination 
chemotherapy are too harmful for you; you need a treatment that is not allowed on this study; new 
information becomes available; if you do not follow the study rules; if you become pregnant or begin to 
breast feed; or if the study is stopped. 
 
 
 
What side effects or risks can I expect from being in the study?  
 
All people who receive cancer treatment are at risk of having side effects.  In addition to killing cancer 
cells, chemotherapy drugs can damage normal tissues and produce side effects.  Side effects are usually 
reversible when the medication is stopped, but occasionally can persist and cause serious complications 
or death. The therapy used in this protocol is made stronger so that it can kill cancer cells quickly before 
they can become resistant to treatment. Protocols used to treat relapsed leukemia or Non-Hodgkin 
lymphoma are more intensive than are those to treat newly diagnosed disease. It is not possible to predict 
whether the side effects listed below, or other rare side effects may occur.  Side effects can be increased 
when chemotherapy drugs are combined.  It is possible that this re-induction therapy will prove better 
than past therapies for relapsed ALL or Non-Hodgkin lymphoma, but it may be no better or worse than 
other treatments. It may be associated with more side effects, which may be life threatening. There also is 
a risk of death. We will tell you if we learn any new information that may affect your health, welfare, or 
decision to stay in this study. You should talk to your study doctor about any side effects that you have 
while taking part in the study.    
 
Common side effects include nausea, vomiting, hair loss and fatigue.  The risks from having your blood 
taken are minimal, but can include an infection or a blood clot. There may be pain and or bruising at the 
site where the needle is inserted to draw your blood. Chemotherapy causes temporary bone marrow 
depression. Bone marrow depression means that your bone marrow may make: 
 
 
Less red cells causing anemia;  
 
Less platelets, causing bruising and an increased chance of bleeding; 
 
Fewer white blood cells, causing a risk for serious infections.

Risks associated with Disease Evaluation Imaging 
X-rays and CT scans expose you to radiation. For PET-CT scan you will get a radioactive sugar (FDG) by 
vein. The radiation exposure for the PET scan is about the same to about half that of a standard CT scan.

You will also get x-rays from the CT portion of the PET-CT scan. The total amount of radiation you get 
from the combined PET and CT scan will not be more than 2 to 6 times the amount of radiation that 
everyone gets in a year from natural sources like the atmosphere.  The risk from this amount of radiation 
is considered to be small when compared with other everyday risks. 
 
Reproductive risks  
Because the drugs in this study can affect an unborn baby, you should not become pregnant or father a 
baby while on this study.  You should not nurse a baby while on this study.  It is a condition of this study that 
adequate birth control methods be used by all participants and/or their sexual partners while enrolled in the 
study. Examples of these include total abstinence (no sex), oral contraceptives (“the pill”), an intrauterine 
device (IUD), Levonorgestrol implants (Norplant), or medroxyprogesterone acetate injections (Depo-provera 
shots).  If one of these methods of birth control cannot be used, contraceptive foam with a condom is 
recommended.  Ask your doctor about counseling and more information about preventing pregnancy. 
 
If you are a female patient and become pregnant or a male patient and your partner becomes pregnant 
during this study, contact your study doctor immediately. Female patients who become pregnant or male 
patients whose partner becomes pregnant will be given instructions for discontinuation of study 
medication and will be removed from study. The maker of temsirolimus (Pfizer, Inc) will be notified if study 
patients become pregnant while taking temsirolimus as part of this study. Adult patients (≥18 years old at 
the time of enrollment or their adult partners (≥18 years old at the time of pregnancy) will be approached 
about consenting to provide more information about the pregnancy if they were taking temsirolimus during 
any part of the pregnancy.  A separate pregnancy consent will be obtained at the time to report any data 
about the pregnancy. 
 
Confidential Information  
Because the sponsor of this study is outside of your medical center, there is the potential small risk of 
accidental release of confidential information when sending out any research documentation.   Please 
see the ”Will my medical information be kept private?” section of this document for more details. 
Developing a Second Cancer 
It is possible that you may develop a second form of cancer as a result of this treatment.  Experience so far 
suggests that the chance of this happening is very small. Not enough information has been gathered in 
children to be able to give an accurate prediction, although it may be in the range of one in every 50 to 800 
children treated.   
 
Are there medications, herbal remedies or foods that I should not take 
while on this study? 
 
The use of the following medications, foods and herbal remedies should be avoided while on 
temsirolimus as it can affect how your body processes the drug.  If you are taking any of these drugs or 
are prescribed these drugs, please let your study doctor know. Your doctor will help find reasonable 
alternatives if you are on one of these drugs.

The following types of medicines used to treat high blood pressure should be avoided while taking 
temsirolimus: 
 
 
Angiotensin converting enzyme inhibitor (ACE inhibitor) 
 
Calcium Channel Blockers (CCB) 
 
Your study doctor can review your medications and tell you if you are currently taking an ACE inhibitor or 
a calcium channel blocker. 
 
Are there benefits to subjects taking part in the study? 
 
Participation on this study may or may not benefit you.  Participating in this study will not cure your 
relapsed leukemia/lymphoma.  Based on experience with the drugs used in the treatment plan, 
researchers believe this therapy may cause your leukemia/lymphoma to stop growing or go into remission 
for a period of time.  Your cancer may not have any response to the therapy received while participating 
in this study.   
 
Are there benefits to society? 
 
It is hoped that the information learned from this study may help future children or young adults with 
relapsed ALL/ Non-Hodgkin Lymphoma.   
 
What other choices do I have if I do not take part in this study? 
 
You do not have to participate in this study to receive treatment for recurrent leukemia.  There is no 
“standard” therapy for recurrent leukemia. Most treatment plans have used drugs similar to those used in 
this protocol, although these drugs may be given in different combinations, and at different times.  You 
can receive other combinations of chemotherapy without participating in this study.   
 
As an alternative to this study, you may decide you don’t want additional treatment for your relapsed 
leukemia or lymphoma.  You will always receive medicines to help you feel more comfortable and deal 
with problems caused by your cancer or treatment whether you participate in this study or not. 
 
Talk to your doctor about your choices before you decide if you will take part in this study. 
 
Will my medical information be kept private?  
 
Members of the research team and, if appropriate, your primary care physicians and nurses will know that 
you are a research subject. All results will be kept confidential, but may be made available to you, and/or 
your physician if you wish.  Because this study involves the treatment of a medical condition, a copy of 
this consent form will be placed in your medical record. This will allow the doctors that are caring for you 
to obtain information about what medications or procedures you are receiving in the study and treat you 
appropriately. You may read your medical record. The records are available to those caring for you at this 
hospital. 
 
Organizations that may inspect/or copy your research records for quality assurance and data analysis 
include: 
 
 
Therapeutic Advances in Childhood Leukemia & Lymphoma Consortium (TACL) 


What are the costs of taking part in this study? 
 
The health care costs during your participation in this study that are considered part of the standard 
treatment of your disease will be billed to your insurance or other third-party payer.  This includes blood 
tests, hospitalizations, procedures that will be done and medications with the exception of the medication 
Temsirolimus.  The drug company, Pfizer, will provide the medication, Temsirolimus, free of charge for 
this study. Pfizer does not cover the cost of getting the Temsirolimus ready and giving it to you, so you or 
your insurance company may have to pay for this. 
 
You will not have to pay for the following tests that will be done for research purposes only: 
- Bone Marrow Biology Studies 
- Peripheral Blood Biology Studies 
 
Your family is responsible for other costs which may result from your participation in the study, such as, but 
not limited to, time off of work, car fare, baby sitter fees, food purchased while at the hospital, etc.  You will 
not receive any type of payment for participating in this study.  Taking part in this study may lead to added 
costs to your insurance company. Please ask about any expected added costs or insurance problems.
