2. BACKGROUND  
 
2.1 Current Status of Lymphoma Care 
 
Despite thirty years of clinical trials, little progress has been made in the treatment of low grade lymphoma 
(Horning, 2003). Patients with low grade lymphomas, as classified by the Working Formulation classification, 
tend to respond initially to approaches as disparate as “watchful waiting”, anthracycline based chemotherapy (in 
conjunction with cyclophosphamide (Dana, et al, 1993) or fludarabine (Klasa, et al, 2002; Velasquez, et al, 2003), 
or stem cell transplant (Bierman, et al, 2003; van Besien, et al, 2003), but invariably the lymphoma recurs in over 
50% of patients within 5 years. There is as such no consensus on upfront therapy that can be designated as 
“standard”. 
 Upon recurrence, remissions can be achieved with further chemotherapy, but the disease free intervals tend to be 
shorter with each line of treatment (Dana, et al, 1993). Allogeneic transplant has been successful in selected 
patients, but with greater treatment related mortality (van Besien, et al, 2003), while autologous high dose 
therapy, with or without the addition of high dose radio-labeled antibodies has not been curative (Gopal 2003). In 
recent years, the additional of Rituxan, a targeted antibody,has shown improved outcome and survival in single 
agent and combination chemotherapy regimens, suggesting that aside from its single agent, it acts as a 
chemosensitizer in lymphoma treatment (Czuczman 2003, Czuczman 2004, Forstpointner 2004). Thus, newer, 
more effective agents are necessary. 
 
2.2 
Vorinostat (Suberoylanilide Hydroxamic Acid (VORINOSTAT)) 
 
Vorinostat, (Zolinza, Suberoylanilide hydroxamic acid; NSC 701852)) is a small molecule inhibitor of histone 
deacetylase (HDAC) that binds directly in the enzyme’s active site in the presence of a zinc ion (Finnin et al., 
1999).  Because aberrant HDAC activity has been implicated in a variety of cancers, development of HDAC 
inhibitors is a rational approach to the design of targeted anticancer therapeutics.  Several HDAC inhibitors from 
multiple chemical classes have been developed and are currently in clinical trials.  Trichostatin and butyric acid 
were among the first HDAC inhibitors to be administered to patients, but these were found to be clinically 
unsuitable due to potency and formulation issues (Gilbert et al., 2001; Gore et al., 2002).  Depsipeptide was 
originally selected for clinical study based on its antiproliferative effects; subsequently it was discovered to 
antagonize HDACs (Sausville, 2003) and was the first HDAC inhibitor to demonstrate clinical efficacy (Piekarz 
et al., 2001).  Of the three classes of HDACs, VORINOSTAT targets most human Class 1 (related to the yeast 
transcriptional regulator Rpd3) and Class 2 (similar to the yeast Hda1) enzymes (Marks et al., 2001a; Kelly et al., 
2002); the third class of HDACs (homologues of yeast sir2) requires NAD+ for activity and is not inhibited by 
VORINOSTAT.  Among those currently in clinical trials, VORINOSTAT is the most potent HDAC inhibitor that 
can be administered orally with excellent bioavailability.  It received FDA approval for treatment in patients with 
Cutaneous T Cell Lymphoma on October 6, 2006. Promising activity is being seen in a current CTEP trial for 
indolent lymphoma, with reports pending on several responses, CR and PR, in refractory indolent lymphoma. 
 
 
2.3 
Rationale 
 
2.3.1 
Mechanism of Action 
 

 
 
The HDACs exert their targeted action during post-translational acetylation of core nucleosomal histones, which 
affects chromatin structure, thereby regulating gene expression.  DNA that is wrapped around condensed, non-
acetylated histones is transcriptionally inactive, whereas acetylation of N-terminal histone lysine residues exposes 
DNA to important transcription factors that promote transcriptional activity (Workman and Kingston, 1998; Arts 
et al., 2003).  The dynamic equilibrium between histone acetylation and deacetylation is regulated by histone 
acetyltransferases (HATs) and HDACs.  The action of HDACs on nucleosomal histones leads to tight coiling of 
chromatin and silencing of expression of various genes, including those implicated in the regulation of cell 
survival, proliferation, differentiation, and apoptosis (Jones and Baylin, 2002).  The effects of HDACs are not 
limited to histone deacetylation.  HDACs also act as members of a protein complex to recruit transcription factors 
to the promoter region of genes, including those of tumor suppressors, and they affect the acetylation status of 
specific cell cycle regulatory proteins (Arts et al., 2003).   
 
2.3.2 Nonclinical 
Activity 
 
VORINOSTAT was identified originally by its ability to induce differentiation of murine erythroleukemia cells at 
micromolar concentrations (Richon et al., 1996; Richon et al., 1998). Subsequently, it was found to induce 
differentiation or arrest growth of a wide variety of human carcinoma cells.  To date, VORINOSTAT activity has 
been reported in transformed hematopoietic cells, such as multiple myeloma (MM) (Feinman et al., 2002; 
Mitsiades et al., 2002; Mitsiades, N. et al., 2003), acute promyelocytic leukemia (APL) (Amin et al., 2001), acute 
lymphocytic leukemia (Guo et al., 2002), chronic myelogenous leukemia (Nimmanapalli et al., 2003; Yu et al., 
2003), Waldenstrom’s macroglobulinemia (Mitsiades, C. et al., 2003), and cutaneous T-cell lymphoma (CTCL) 
(Zhang et al., 2003).  Activity has also been reported in cell lines representing other tumor types including 
bladder transitional cell carcinoma (Richon et al., 2000), breast cancer (Huang et al., 2000; Munster et al., 2001; 
Said et al., 2001), prostate cancer (Butler et al., 2000), head and neck squamous carcinoma (Gillenwater et al., 
2002), and colon carcinoma (Peart et al., 2003). 
The antitumor activity of VORINOSTAT was demonstrated in several in vivo models of cancer, including a 
xenograft model of human CWR22 prostate cancer cells (Butler et al., 2000), a mouse model of APL containing 
the promyelocytic leukemia zinc-finger-retinoic acid receptor α fusion gene (PLZF-RARα) (He et al., 2001), and 
an N-methylnitrosourea-induced mammary tumor model in rodents (Cohen et al., 1999).  VORINOSTAT has also 
showed activity when administered daily by intraperitoneal (IP) injections in the CWR22 and PLZF-RARα 
models and by oral (PO) administration in the carcinogen-induced mammary tumor model. 
 
2.3.3 
VORINOSTAT Combination Studies 
 
Accumulating evidence has demonstrated the effectiveness of HDAC inhibitors in combination with several other 
agents in vitro.  The combination of VORINOSTAT and DNA hypomethylating agents (5-azacytidine or 
decitabine) acts synergistically to induce apoptosis, differentiation, and/or cell growth arrest in various cancer cell 
lines (Tabe et al., 2002; Zhu and Otterson, 2003).  When VORINOSTAT was combined with the anti-metabolite 
5-fluorouracil, a supra-additive to additive antiproliferative effect in wild type and mutant-p53 colorectal cancer 
cells was observed (Di Gennaro et al., 2003).  VORINOSTAT with imatinib mesylate (Gleevec®) may be 
effective in chronic myelogenous leukemia (CML) cells that resist imatinib mesylate through increased Bcr-Abl 
expression (Nimmanapalli et al., 2003; Yu et al., 2003).  Minimally toxic concentrations of the proteasome 
inhibitor bortezimib combined with VORINOSTAT resulted in increased apoptosis in human leukemia cells (Yu 
et al., 2003).  In cells from RARα-PLZF/RARα-PLZF transgenic mice and in cells harboring t(15;17) (RARα-
PML fusion genes), VORINOSTAT induced significant apoptosis and growth inhibition, effects that were 
increased by adding all-trans retinoic acid (He et al., 2001).  Pre-treating four human cancer cell lines (including a 
brain tumor line) with VORINOSTAT increased the killing efficiency of etoposide, ellipticine, doxorubicin, or 
cisplatin, but not of the topoisomerase I inhibitor camptothecin (Kim et al., 2003).  However, treating cells in the 
reverse order (anticancer drug followed by VORINOSTAT) was no more cytotoxic than the anticancer drug 
alone.  Finally, overexpression of Bcl-2 or Bcl-XL in leukemia and MM cell lines abolished VORINOSTAT-

 
 
induced apoptosis but did not affect its differentiation or cell cycle regulatory effects (Vrana et al., 1999; 
Mitsiades, N. et al., 2003; Peart et al., 2003).  This suggests that agents blocking Bcl-2 expression or function 
could be effectively combined with VORINOSTAT.  Studies done with other HDACs have suggested that a 
consequence of HDAC inhibitor-induced heat shock protein 90 (Hsp 90) acetylation is depletion of the Hsp 90 
client protein Her-2 and increased apoptosis of breast cancer cell lines induced by taxotere, trastuzumab, 
epothilone B, and gemcitabine (Fuino et al., 2003; Yu et al., 2002).  In addition to these potentially additive or 
synergistic interactions between VORINOSTAT or other HDACs and various anticancer drugs, VORINOSTAT 
has shown synergistic activity when combined with radiotherapy in prostate cancer cell spheroids (Sgouros et al., 
2002). 
 
2.3.4 
Phase 1 Clinical Experience 
 
A phase 1 study evaluated VORINOSTAT administered intravenously (IV) to patients with advanced solid 
tumors and hematologic malignancies (Kelly et al., 2003).  VORINOSTAT was administered using two 
schedules:  2-hour IV infusion daily X 3 q21d, or daily X 5 for 1 to 3 weeks.  No dose-limiting toxicities (DLTs) 
were observed in eight patients administered VORINOSTAT daily X 3 q21d at doses of 75, 150, 300, 600, and 
900 mg/m²/day.  One solid tumor patient given 900 mg/m² on the daily X 5 schedule for 3 weeks developed acute 
respiratory distress and grade 3 hypotension.  Among five other patients at this dose, no additional DLTs were 
observed.  Among 12 hematologic and 17 solid tumor patients enrolled on the daily X 5 schedule (300, 600, and 
900 mg/m²/day), therapy was delayed >1 week for grade 3/4 leukopenia and/or thrombocytopenia in two of five 
patients with hematologic malignancies given 600 mg/m² for 3 weeks.  The maximum tolerated dose (MTD) for 
hematologic malignancy patients was 300 mg/m² daily X 5 for 3 weeks.  An MTD for solid tumors was not 
determined because the study was terminated when an oral formulation became available. The mean terminal half-
life (t1/2) ranged from 21 - 58 minutes, and the dose was linearly proportional to the area under the concentration 
versus time curve (AUC).  Acetylated histones were detected in peripheral blood mononuclear cells (PBMCs) up 
to 4 hours post-infusion at higher dose levels.  This observation was confirmed by immunohistochemical analyses 
of post-therapy tumor biopsies.  Four patients, including two with lymphoma and two with bladder cancer, 
experienced objective tumor regression with clinical improvement in tumor-related symptoms. 
 
As of June 2004, VORINOSTAT capsules have been administered to 143 patients with advanced solid tumors or 
hematologic malignancies in three phase 1 trials and three phase 2 trials (Investigator’s Brochure, 2004) at total 
daily doses ranging from 200 to 900 mg.  The MTD of continuous dosing (no rest period) of oral VORINOSTAT 
is 400 mg q.d. or 200 mg b.i.d.  When the agent is given intermittently, the MTD is 300 mg b.i.d. daily × 3 days 
per week or 250 mg t.i.d. x 14 days followed by 7 days of rest.  The DLTs are non-hematologic (anorexia, 
dehydration, diarrhea, and fatigue).  The most common hematologic adverse events are anemia and 
thrombocytopenia, which are rapidly reversible after study drug interruption.  Pharmacokinetic analysis of 26 
patients has indicated that the bioavailability of oral VORINOSTAT is approximately 46%.  VORINOSTAT 
doses in the range of 200 - 600 mg produced maximum concentration (Cmax) and drug exposure (AUC) curves that 
were linearly proportional.  The t1/2 of oral VORINOSTAT ranges from 92 to 150 minutes, and preliminary data 
suggest that administration of VORINOSTAT with food does not appear to substantially alter the rate or extent of 
absorption.  Inhibition of HDAC activity was achieved in PBMCs at the 200 mg dose level.  At dose levels of 400 
and 600 mg, the duration of HDAC inhibition lasted >10 hours.  
 
Significant antitumor activity has been observed among members of the above patient population.  In the ongoing 
phase 1 study of oral VORINOSTAT, seven patients with heavily pre-treated diffuse large B-cell lymphoma were 
entered.  Among these patients, one complete response (CR) and one partial response (PR) were observed.  In 
addition, one patient has had a significant PET scan response.  The PR lasted 5 months, the PET scan response 
lasted 6 months, and the CR is ongoing with a duration >12 months.  Decrease in tumor mass, pleural effusion, 
and improvement of tumor-related pain or shortness of breath have also been observed in patients with 
mesothelioma.  In an ongoing phase 2 study of VORINOSTAT in patients with heavily pretreated CTCL or 
peripheral T-cell lymphoma, objective responses have been observed (including PRs in 5 of 13 patients), and 8 of 

 
 
10 patients reported decreased pruritus. In the published Phase I study of VORINOSTAT, the MTD was 
identified as 200 mg PO bid for continuous dosing and 300 mg PO bid for three-day-per-week dosing (Kelly WK, 
et al 2005) 
 
Based on the data from these clinical studies, the recommended doses and schedules of oral VORINOSTAT 
administration for phase 2 trials are 400 mg q.d., 200 mg b.i.d., or 300 mg b.i.d. daily × 3 days per week in 
patients with either solid tumors or hematologic malignancies. 
 
2.3.5 
Potential for Drug Interactions 
 
In laboratory studies using cultured human hepatocytes, statistically significant and concentration-dependent 
suppression of the P450 isoenzymes CYP2B6, 2C9, and 2C19 was seen at concentrations exceeding the levels 
achieved following oral administration (10 to 50 μM) of VORINOSTAT, while CYP3A4 suppression was 
observed at clinically relevant (2 μM) concentrations of the agent (Investigator’s Brochure, 2004).  These effects 
could be the result of VORINOSTAT-induced changes in the cellular machinery that generates these enzymes or 
VORINOSTAT metabolites. These observations suggest that the potential exists for interactions between 
VORINOSTAT and concurrently administered drugs, over-the-counter medication, or alternative therapies.  For 
this reason, caution should be observed when treating patients taking any agent found in Appendix C, a list of 
drugs or substances known to affect or with the potential to affect selected P450 isoenzymes. 
 
2.3.6 
Use of VORINOSTAT in Lymphoma 
 
There is good preclinical evidence to support the use of HDAC inhibitors in lymphoid malignancies. Increased 
histone acetylation has been shown to regulate terminal B cell differentiation, as well as to cause apoptosis via 
upregulation of p21waf-1/cip1. .Several natural agents have been shown to have HDAC inhibitory activity, however 
the orally bioavailable synthetic compound, suberoylanilide hydroxamic acid, has to been shown to effectively 
bring about increased histone acetylation in B cell malignancies. VORINOSTAT induces growth arrest and 
apoptosis in B cell tumor lines,at least in part via upregulation of p21waf-1/cip1, in a caspase independent manner. B 
cell tumor lines were more sensitive to VORINOSTAT than solid tumor lines in vitro (Mitsiades, et al 2003).  
In clinical trials as well, responses among patients with lymphoid malignancies were prominent. In the initial 
phase I study using IV VORINOSTAT, of the four responders, two were lymphoma patients (Kelly, et al, 2003)  
In the ongoing phase I studies, there were two responders among the seven lymphoma patients, one CR and one 
PR. In a Phase II trial of VORINOSTAT in cutaneous T cell lymphoma presented at this year’s ASH meeting, 
five out of 13 patients were partial responders, and in a Phase I study presented at last year’s meeting reduction in 
tumor size was seen in six out of 21 heavily pretreated patients with NHL and Hodgkin’s lymphoma. In our 
ongoing phase II study of vorinostat alone in relapsed or refractory indolent lymphoma patients, at the first stage 
evaluation point, 4 CR, 2 PR, and several patients with prolonged stable disease were seen; the trial is currently 
accruing to the second stage. Thus, a combination trial with rituxan in upfront, relapsed, and refractory patients is 
indicated.  
 
2.3.7 
Rituximab (IDEC-C2B8, Rituxan) 
 
Rituximab is a chimeric IgG1 monoclonal antibody  targeting the CD20 surface antigen present on both normal 
lymphocytes and B-cell lymphomas. The activity of this agent is multifaceted, in that it leads to direct lysis by 
complement activation as well as antibody dependant cell mediated cytotoxicity, triggers apoptosis, and may lead 
to various signaling pathway changes in targeted cells (reviewed in Cartron 2004). Aside from its direct effect, it 
appears to also act as a chemosensitizer by blocking IL-10 binding, leading to decreased intracellular bcl-2 ,  and 
a pro-apoptotic environment (Demidem, 1997, Alas D 2001). This suggests that rituximab may synergise with 
vorinostat’s pro-apoptotic activity. It is thus reasonable to combine the two agents, vorinostat and rituximab, in 
indolent lymphomas. 

 
 
 
 
Given the activity seen in relapsed and refractory patients with vorinostat alone, we propose a Phase II study of 
vorinostat at 200 mg PO b.i.d. on a two week on, one week off schedule in patients with low grade lymphomas in 
combination with rituximab, at 375 mg/m2 given every three weeks on day 1 of the cycle along with vorinostat. 
Included in this cohort are patients with low-grade lymphomas according to the Working Formulation classification, 
newly diagnosed or who have recurred after rituxan and/or chemotherapy.  
 
3. PATIENT SELECTION 
 
3.1  Eligibility Criteria 
 
3.1.1 
Patients must have histologically or cytologically confirmed indolent Non-Hodgkin’s Lymphoma 
(Included in this category are newly diagnosed or relapsed/refractory follicular center lymphomas 
grade I, II, III, relapsed /refractory marginal zone B-cell lymphoma (nodal and extranodal), 
relapsed/refractory mantle cell lymphoma).    
 
3.1.2 
Patients must have measurable disease by CT scan. PET scan evaluations are desirable but not 
mandatory, so that patients with negative PET scans but measurable disease by CT are eligible. 
 
3.1.3 
Patients may have had up to four prior chemotherapeutic regimens. Steroids alone and local radiation 
do not count as regimens (Radiotherapy must have been completed at least 14 days prior to starting 
vorinostat). Rituxan alone does not count as a regimen, however, Bexxar or Zevalin do.  For treated 
patients, the most recent therapy must have failed to induce a complete response (i.e. there is 
persistent disease by CT or PET), or there must be disease progression or recurrence after the most 
recent therapy.  
 
3.1.4   
Patients may be enrolled who relapse after autologous stem cell transplant if they are at least three 
months after transplant, and after allogeneic transplant if they are at least six months posttransplant. 
To be eligible after either type of transplant, patients should have no active related infections (i.e. 
fungal or viral). In the case of allogeneic transplant relapse, there should be no active acute graft 
versus host disease (GvHD) of any grade, and no chronic Graft versus Host disease other than mild 
skin, oral, or ocular GvHD not requiring systemic immunosuppression.     
 
3.1.5 
Age 18 years.  Because no dosing or adverse event data are currently available on the use of 
VORINOSTAT in patients <18 years of age, children are excluded from this study but will be eligible 
for future pediatric single-agent trials, if applicable. 
 
3.1.6 
Life expectancy of greater than 3 months. 
 
3.1.7 
ECOG performance status 2 (Karnofsky 60%; see Appendix A). 
 
3.1.8 
Patients must have normal organ and marrow function as defined below: 
 
 
Absolute Neutrophil Count 
>1,000/mcL 
 
platelets 
>100,000/mcL 
 
total bilirubin 
within normal institutional limits; patients with elevation of 
unconjugated bilirubin alone, as in Gilbert’s Disease, are eligible. 
 
AST(SGOT)/ALT(SGPT) 
2.5 X institutional upper limit of 
 
 
 
 
 
 
 
 
 
normal creatinine up to and including 2 mg/dl 

 
 
 
3.1.9  
Pre-menopausal women must have a negative serum pregnancy test prior to entry on this study. The 
effects of VORINOSTAT on the developing human fetus at the recommended therapeutic dose are 
unknown.  For this reason and because HDAC inhibitors are known to be teratogenic, women of 
child-bearing potential and men must agree to use adequate contraception (hormonal or barrier 
method of birth control; abstinence) prior to study entry and for the duration of study participation.  
Should a woman become pregnant or suspect she is pregnant while participating in this study, she 
should inform her treating physician immediately. 
 
3.1.10 
Ability to understand and the willingness to sign a written informed consent document. 
 
3.2  
Exclusion Criteria 
 
 3.2.1  
Patients who have had chemotherapy within 4 weeks, or radiotherapy within 2 weeks or those who 
have not recovered from adverse events due to agents administered more than 4 weeks earlier are 
excluded. This does not include use of steroids, which may continue until two days prior to 
enrollment. Low dose chlorambucil should be stopped two weeks prior to beginning VORINOSTAT. 
Valproic acid should be stopped at least two weeks prior to enrollment. Nitrosureas and mitomycin 
should be stopped 6 weeks prior to enrollment. 
 
3.2.2 
Patients may not be receiving any other investigational agents. 
 
3.2.3 
Patients with known brain metastases are excluded from this clinical trial unless the metastases are 
controlled after therapy and have not been treated with steroids within the past two months. 
 
3.2.4 
History of allergic reactions attributed to compounds of similar chemical or biologic composition to 
VORINOSTAT. 
 
3.2.5 
There must be no plans for the patient to receive concurrent hormonal, biological or radiation therapy. 
 
3.2.6 
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, 
symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric 
illness/social situations that would limit compliance with study requirements.  
 
3.2.7 
Pregnant women are excluded from this study because VORINOSTAT is a HDAC inhibitor agent 
with the potential for teratogenic or abortifacient effects.  Because there is an unknown but potential 
risk for adverse events in nursing infants secondary to treatment of the mother with VORINOSTAT, 
breastfeeding should be discontinued if the mother is treated with VORINOSTAT. 
 
3.2.8 
HIV-positive patients receiving combination antiretroviral therapy are ineligible because of the 
potential for pharmacokinetic interactions with VORINOSTAT.  In addition, HIV patients not 
receiving combination antiretroviral therapy are also ineligible as these patients are at increased risk 
of lethal infections when treated with marrow-suppressive therapy.    
 
 
 
3.2.9 
Patients with other active malignancies are ineligible for this study. 
 
3.2.10 Patients with preexisting or previous coagulation issues are not excluded from study as long as 1) 
previous pulmonary embolism or deep vein thrombosis have been adequately treated or 2) if they are 
actively receiving Coumadin or lovenox for anticoagulation.  Patients who are already on Coumadin 
or Lovenox do not need to take additional 40 mg subcutaneous injections daily.  
 

 
 
3.3 
Inclusion of Women and Minorities 
 
Both men and women and members of all races and ethnic groups are eligible for this trial.   
 
4. TREATMENT PLAN 
 
4.1  
Suberoylanilide Hydroxamic Acid (VORINOSTAT) Administration 
 
Treatment will be administered on an outpatient basis.  Reported adverse events and potential risks are 
described in Section 6.  Appropriate dose modifications for VORINOSTAT are described in Section 5.  No 
investigational or commercial agents or therapies other than those described below may be administered with 
the intent to treat the patient’s malignancy. 
 
A cycle of therapy will consist of VORINOSTAT 200mg twice daily administered orally for 14 days 
followed by a seven day break on a 21 day cycle for the first cycle.  If tolerated, the dose may be increased 
after the 2nd cycle to 200 mg TID x 14/21 days. If necessary, dose de-escalation may be instituted by reducing 
one of the daily doses by 100 mg; so, for example, patients might receive an am dose of 300 mg and a pm 
dose of 200 mg. Rituximab will be infused on day 1 of each cycle at the standard dose of 375 mg/m2 
Radiological assessment by CT and/or PET scan will take place at baseline and after every three cycles (every 
3 months). Response will be assessed by standard criteria (Cheson BD, et al 1999). Toxicity will be assessed 
on days 1 and 8 of every cycle, and graded using the NCI CTCAE version 3.0. Patients with measurable 
response or stable disease may continue receiving VORINOSTAT until progression. Patients who achieve 
CR will receive two further cycles of VORINOSTAT plus rituximab and then discontinue drug. Patients who 
achieve complete response may be restarted on drug in the event of relapse six months or greater from the 
time of initial CR, given the chronic relapsing nature of indolent lymphomas. Compliance with treatment will 
be monitored by use of drug diaries.  
 
Because many drugs including antineoplastic agents are metabolized by the cytochrome P450 system, there is 
a potential for interaction of VORINOSTAT with concomitantly administered drugs.  The case report form 
must capture the concurrent use of all other drugs, over-the-counter medications, or alternative therapies.   
 
Patient compliance will be monitored using drug diaries, which will be reviewed on day 1 of each cycle after 
cycle 1. 
 
4.2 
Rituximab Administration 
 
Rituximab will be administered at a dose of 375 mg/m2 on day 1 of every cycle, every three weeks. 
The initial dose rate should be 50 mg/hour IV for the first hour.  If no toxicity is seen, the dose rate may be 
escalated gradually to a maximum of 400 mg/hour.  Subsequent doses have required much less infusion time. 
 If the first dose of rituximab is well tolerated, the starting flow rate for subsequent doses is 100 mg/hour, 
then increased gradually (100 mg/hour increments at 30-minute intervals) not to exceed 400 mg/hour.   
 
Patients may experience transient fever and rigors with infusion.  When these occur, the antibody infusion 
should be temporarily discontinued or slowed.  When symptoms improve, the infusion should be resumed, 
initially at half the previous rate.  Following the antibody infusion, the intravenous line should be kept open 
for medications, as needed.  If there are no complications, the intravenous line may be discontinued after one 
hour of observation. 
 
Oral premedication (acetaminophen and diphenhydramine hydrochloride) may be administered 30 to 60 
minutes prior to starting each infusion of rituximab. 
 

 
 
Lovenox Administration 
 
Lovenox (enoxaparin) will be administered at a dose of 40 mg subcutaneously daily.  Patients will be 
educated by nursing staff on how to perform daily injections.  Administration should be alternated between 
left and right anterolateral and left and right posterolateral abdominal wall.  The whole length of the needle 
should be introduced into a skin fold held between the thumb and the forefinger.  The skin fold should be 
held throughout the injection.   
 
 
4.3 
Supportive Care Guidelines 
 
4.3.1 Antiemetics 
 
Individualization of antiemetic treatment for patients receiving VORINOSTAT is required, as some patients 
require no antiemetic therapy, while others may require more intense therapy. Recommended antiemetics 
include: ondansetron, prochlorperazine, metoclopramide, lorazepan, or diphenhydramine. It is recommended 
that steroids not be used for anti-emesis. 
 
4.3.2  Chemotherapy 
 
 
 
 
Concurrent chemotherapy is not allowed in this study.  
 
4.3.3  Complimentary or Alternative medications 
 
Patients may not take CAM medications while on protocol. Routine vitamin supplementation is allowed. 
 
4.3.4  Growth Factors 
 
Patients already on erythropoeitin or aranesp for lymphoma related anemia may continue to use these agents. 
Use of G-CSF or erythropoeitin is allowed after the first cycle. 
 
4.3.5 Radiation Therapy 
 
Patients who require localized external beam radiotherapy at the time of protocol screening should receive it 
prior to study entry. 
 
Patients who require localized external beam radiotherapy during study will be considered to have 
progression of lymphoma and will be removed from study. 
 
4.3.6 Diarrhea 
 
Treat diarrhea promptly with appropriate supportive care, including loperamide. Instruct patients to begin taking 
loperamide at the first signs of: 1) poorly formed or loose stool, 2) occurrence of more bowel movements than 
usual in one day, or 3) unusually high volume of stool. Loperamide should be taken in the following manner: 4 
mg at first onset of diarrhea, then 2 mg after each unformed stool. Daily dose should not exceed 16 mg/day. 
Loperamide should not be taken prophylactically. Advise patients to drink plenty of clear fluids to help prevent 
dehydration caused by diarrhea. Avoid loperamide if there is the presence of blood or mucus in the stool or if 
diarrhea is accompanied by fever.  
4.3.7 Oral Intake and Hydration 
 

 
 
Care should be taken to ensure adequate hydration during and after treatment. Popsicles and Gatorade have 
been found to be useful in this setting. 
 
4.3.8 Anticoagulation prophylaxis 
 
Patient will need to take Lovenox 40 mg subcutaneously daily when patients are getting active treatment with 
vorinostat and rituxan.  Five research participants on this study have developed either pulmonary embolism or 
deep vein thrombosis.  These have been without symptoms and found on CT scans.       Lovenox (40 mg) 
subcutaneously will be taken starting from Cycle 1 Day 1 of study to prevent pulmonary embolus and deep 
vein thrombosis.  Lovenox will continue for at least 28 days status post last dose of vorinostat or rituximab.  
For patients with creatinine clearance less than 30 ml/min, lovenox dose will be 30 mg subcutaneously daily. 
 Elderly patients with creatinine clearance less than 50 ml/min should also be dosed at 30 mg subcutaneously 
daily. 
 
 
4.4  
Duration of Therapy 
 
Patients who achieve CR as defined in section 9 will receive two further cycles of VORINOSTAT plus 
rituximab and then discontinue drug. Radiologic studies will be continued every three months for the first 
year, and at a minimum of every six months for the next two years. 
In the absence of treatment delays due to adverse event(s), treatment may continue until one of the following 
criteria applies: 
 
 
Disease progression, 
 
 
Intercurrent illness that prevents further administration of treatment, 
 
 
Unacceptable adverse event(s), 
 
 
Patient decides to withdraw from the study, or 
 
 
General or specific changes in the patient’s condition render the patient unacceptable for further 
treatment in the judgment of the investigator. 
 
4.5 
Duration of Follow Up 
 
Patients will be followed until disease progression is noted or until death, whichever occurs first.  Patients 
removed from study for unacceptable adverse events will be followed until resolution or stabilization of the 
adverse event. 
 
5. DOSING DELAYS/DOSE MODIFICATIONS 
 
5.1  
Vorinostat Dose Reductions for Toxicity: 
 
Treatment will be administered at 100 mg daily less than their previous dose for patients who present to 
treatment and are found to have ANC 500, but ≤ 1000, or platelet counts 50K but ≤75K. This dose 
reduction is reversible with normalization of counts.  
 
 
Treatment will be held for patients who present with: 

 
 
1. non-hematologic toxicity of grade 3 or 4, until toxicity resolves to below grade 2. These patients will 
restart at 100 mg daily less than their previous dose. If this dose leads to recurrence of the toxicity at grade 3 
or greater, the patient will come off study. 
2. hematologic toxicity of ANC <500, or platelet count <50K. Should dose need to be held for greater than 
two weeks, upon recovery of ANC >1000 or platelet count >50 patient may restart at 100 mg daily less than 
their previous dose. If this dose also leads to ANC<500 or platelet count <50, then patient should come off 
study. 
 
Treatment will be discontinued in patients who experience toxicity of grade 3 or greater that does not resolve 
within 3 weeks. Requirement for more than two dose reductions mandates removal from the study. Delay of 
protocol treatment for more than four weeks from date of scheduled treatment mandates removal from 
protocol treatment, unless there are extenuating circumstances and approved by the principal investigator.  
 
Lovenox Dose Reductions for Toxicity: 
Hematologic Toxicity:  If platelet count drops to <50K, lovenox should be held until platelets recover. 
 
 
 
5.2 
Treatment Delays and Schedule Modification 
 
Brief interruptions and delays in the 21-day cycle may occasionally be required due to travel delays, airport 
closure, inclement weather, family responsibilities, security alerts, government holidays, etc. This can also 
extend to complications of disease or unrelated medical illness not related to disease progression. These 
delays will not be considered protocol violations. 
 
 
6. PHARMACEUTICAL INFORMATION 
 
6.1 
Suberoylanilide Hydroxamic Acid (NSC 701852) 
 
Chemical Name: 
N-hydroxy-N’-phenyl-octane-1,8-diotic acid diamide;  
N-hydroxyl-N’-phenyl (9CI) octanediamide  
 
Other Names:  
VORINOSTAT, L-001079038, WIN 64652, MSK390, AP390 
 
Classification:  
Antineoplastic 
 
CAS Registry Number: 
149647-78-9 
 
Molecular Formula: 
C14H20N203 
 M.W.: 
264 
 
Approximate Solubility:  
Water < 5 mg/mL 
 
Description:  
Histone deacetylase (HDAC) inhibitor  
 
Mode of Action:  
Histone deacetylases (HDACs) are a family of enzymes that regulate chromatin remodeling 
and gene transcription via the dynamic process of acetylation and deacetylation of core 
histones. 
 
Suberoylanilide hydroxamic acid, a potent inhibitor of HDAC activity, binds directly to the 
catalytic pocket of HDAC enzymes. VORINOSTAT causes G1 or G2 phase cell-cycle arrest, 
apoptosis, or differentiation in cultured transformed cells. 

 
 
 
How Supplied:  
Suberoylanilide hydroxamic acid is supplied by Merck and Co., Inc.  Suberoylanilide 
hydroxamic acid is supplied in the following strengths: 
1. a white, opaque gelatin capsule containing 100 mg (size 3 capsule) of 
suberoylanilide hydroxamic acid  
2. a white, opaque gelatin capsule containing 200 mg  (size 1 capsule) of 
suberoylanilide hydroxamic acid. 
 
The inactive ingredients contained in each capsule are microcrystalline cellulose, sodium 
croscarmellose, and magnesium stearate.  
 
Suberoylanilide hydroxamic acid 100 mg capsules are supplied in bottles of 120 capsules and 
200 mg capsules are supplied in bottles of 100 capsules. 
 
Storage:  
Store suberoylanilide hydroxamic acid capsules at room temperature, 15 to 30 ºC (59 to 86 
ºF).  Transient temperature spikes up to 40 ºC (104 ºF) for up to 24 hours are permissible. 
 
Stability: 
Shelf life stability studies of the intact bottles are ongoing. 
 
Route of Administration:  
Orally 
 
Method of Administration:  
Unless otherwise stated in the protocol, suberoylanilide hydroxamic acid 
capsules must be administered whole. The absolute bioavailability of 
suberoylanilide hydroxamic acid under fasted or fed conditions is approximately 
46%. Oral administration with food does not appear to substantially alter the rate 
or extent of absorption. 
 
Potential Drug Interactions: 
In cultured human hepatocytes, suberoylanilide hydroxamic acid was shown to 
inhibit CYP2B6, CYP2C9, CYP2C19, and CYP3A4 isoenzymes. Therefore, it 
is possible that suberoylanilide hydroxamic acid may interact with drugs that are 
metabolized by the P450 CYP isoenzymes. Caution should be exercised when 
combining the study agent with medications that are metabolized by these 
isoenzymes. 
 
Special Handling: 
VORINOSTAT is an anticancer drug. Powder spills from VORINOSTAT capsules 
due to damaged or broken capsules should be cleaned up carefully so as to 
minimize inhalation. The affected area must be washed at least 3 times with ethyl 
alcohol, followed by water. 
 
Patient Care Implications: 
Because VORINOSTAT’s dose limiting toxicities are anorexia, dehydration, 
diarrhea, and fatigue, patients should maintain adequate fluid and food intake. 
Encourage patients to seek a nutritional consult.

Side effects 
 
1. Infusion related symptoms: Fevers, chills, rigors, hypotension, anaphylaxis or hypersensitivity reactions, 
arrhythmia, dyspnea, bronchospasm, angioedema.  In rare cases, severe and fatal cardiopulmonary 
events, including hypoxia, pulmonary infiltrates, acute respiratory distress syndrome, myocardial 
infarction, and cardiogenic shock, have occurred (4-7/10,000 patients or 0.04-0.07%.)  Nearly all fatal 
infusion-related events occurred in association with the first infusion. Patients with preexisting cardiac 
conditions, including arrhythmia and angina, have had recurrences of these cardiac events during 
rituximab infusions. 
 
2. Gastrointestinal: Nausea, vomiting. 
 
3. Hematologic: Leukopenia, anemia, thrombocytopenia.  In clinical trials, NCI CTC Grade 3 and 4 
cytopenias were reported in 48% of patients treated with rituximab; these include: lymphopenia (40%), 
neutropenia (6%), leukopenia (4%), anemia (3%), and thrombocytopenia (2%).  The median duration of 
lymphopenia was 14 days (range, 1 to 588 days) and of neutropenia was 13 days (range, 2 to 116 days).  
A single occurrence of transient aplastic anemia (pure red cell aplasia) and two occurrences of hemolytic 
anemia following rituximab therapy were reported.  
 
In addition, there have been a limited number of postmarketing reports of prolonged pancytopenia, 
marrow hypoplasia, and late onset neutropenia (defined as occurring 40 days after the last dose of 
rituximab) in patients with hematologic malignancies.  In reported cases of late onset neutropenia (NCI-
CTC Grade 3 and 4), the median duration of neutropenia was 10 days (range 3 to 148 days).  
Documented resolution of the neutropenia was described in approximately one-half of the reported cases; 
of those with documented recovery, approximately half received growth factor support.  In the remaining 
cases, information on resolution was not provided.  More than half of the reported cases of delayed onset 
neutropenia occurred in patients who had undergone a prior autologous bone marrow transplantation.  In 
an adequately designed, controlled, clinical trial, the reported incidence of NCI-CTC Grade  3 and 4 
neutropenia was higher in patients receiving rituximab in combination with fludarabine as compared to 
those receiving fludarabine alone (76% [39/51] vs. 39% [21/53]).33 
 
4. Dermatologic: Rash, pruritus, urticaria, and rarely severe mucocutaneous reactions.  
 
5. Infectious: Reactivation of hepatitis B; reactivation of other viral infections or increased susceptibility to 
other infections.  Hepatitis B virus (HBV) reactivation with fulminant hepatitis, hepatic failure, and death 
has been reported in some patients with hematologic malignancies treated with rituximab.  The majority 
of patients received rituximab in combination with chemotherapy.  The median time to the diagnosis of 
hepatitis was approximately four months after the initiation of rituximab and approximately one month 
after the last dose. 
 
6. Renal and electrolyte: Renal toxicity has occurred in patients with high numbers of circulating malignant 
cells (>25,000/mm2 ) or high tumor burden who experience tumor lysis syndrome. Although rare, tumor 

 
 
lysis syndrome has been reported in postmarketing studies and is characterized in patients with a high 
number of circulating malignant cells (>25,000 ul) by rapid reduction in tumor volume, renal 
insufficiency, hyperkalemia, hypocalcemia, hyperuricemia, and hyperphosphatemia 
 
7. Other: Headache, asthenia.  The following immune serious adverse events have been reported to occur rarely 
(<0.1%) in patients following completion of rituximab infusions: arthritis, disorders of blood vessels 
(vasculitis, serum sickness and lupus-like syndrome), lung disorders including pleuritis and scarring of the 
lung (bronchiolitis obliterans), eye disorders (uveitis and optic neuritis), and severe bullous skin reactions 
(including toxic epidermal necrolysis and pemphigus) that may result in fatal outcomes.  Patients may have 
these symptoms alone or in combination with rash and polyarthritis.  Five patients have developed deep vein 
thrombosis or pulmonary embolism as well.  These were asymptomatic and found incidentally on CT scans.   
Nursing implications 
 
1. Monitor vital signs prior to Rituximab and if the patient has clinical deterioration during the infusion. 
 
2. Have epinephrine for subcutaneous injections, diphenhydramine for intravenous injection, and 
resuscitation equipment for emergency management of anaphylactoid reactions available. 
 
3. Monitor and alter infusion rates in the presence of toxicities. 
 
4. Prolonged pancytopenia and bone marrow hypoplasia have been submitted as postmarketing reports. 
Patients should be monitored closely. 
 
5. Prophylaxis for tumor lysis syndrome should be used in patients with high tumor burden, particularly 
with markedly elevated numbers of circulating malignant cells. Precautionary hospitalization should be 
made available for patients who experience severe infusion symptoms, which do not resolve after 
discontinuation or completion of the infusion. 
 
6. Observe the patient for mucositis with sore throat or mouth ulcers followed by a diffuse skin rash. Skin 
reactions can be life threatening and lead to fatal Stevens-Johnson syndrome or toxic epidermic 
necrolysis.  Patients should be instructed to be observant for signs and symptoms of skin reaction.  
Patients who develop a sore throat, mucositis should be evaluated and monitored very closely for 
development of skin reaction, and hospitalized and treated with corticosteroids if indicated. Patients who 
develop evidence of significant skin rash, oral pharyngeal mucositis that are thought to be related to 
rituximab should be taken off the study.

WARNING: SPINAL/EPIDURAL HEMATOMA 
Epidural or spinal hematomas may occur in patients who are anticoagulated with low molecular weight 
heparins (LMWH) or heparinoids and are receiving neuraxial anesthesia or undergoing spinal puncture. These 
hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for 
spinal procedures. Factors that can increase the risk of developing epidural or spinal hematomas in these 
patients include: 
 
Use of indwelling epidural catheters  
 
Concomitant use of other drugs that affect hemostasis, such as non-steroidal anti-inflammatory drugs 
(NSAIDs), platelet inhibitors, other anticoagulants  
 
A history of traumatic or repeated epidural or spinal punctures  
 
A history of spinal deformity or spinal surgery.  
Monitor patients frequently for signs and symptoms of neurological impairment. If neurological compromise is 
noted, urgent treatment is necessary. 
 
Consider the benefits and risks before neuraxial intervention in patients anticoagulated or to be anticoagulated 
for thromboprophylaxis [see Warnings and Precautions (5.1) and Drug Interactions (7)].

phosphorus, potassium, total protein, SGOT [AST], SGPT [ALT], sodium. 
d: Off-study evaluation.  
g. Patients with partial response or stable disease may continue to receive VORINOSTAT until progression. Patients who 
achieve CR will receive two further cycles of VORINOSTAT and then discontinue drug. Follow up radiological studies 
will continue every three months for one year, then every six months for the next two years. 
h. Bone Marrow aspiration and biopsy may be performed up to four weeks prior to starting study drug, and if positive 
should be repeated every three cycles. 
i. For details see section 11. 
j. After one year of treatment, if the patient achieved two consecutive PR based on prior CT scans or PET, the radiological 
assessment can be done after every 4 cycles instead of 3 cycles.  If patients achieved CR, follow up radiological studies 
will continue every 3 months for one year, then every six months for the next two years.   

 
 
 
8. MEASUREMENT OF EFFECT 
 
For the purposes of this study, patients should be reevaluated for response every three cycles (~ 9 weeks) by 
radiological and marrow studies as described in the study calendar (section 8). After one year of treatment, if the 
patient achieved two consecutive PR based on prior CT scans or PET, the radiological assessment can be done after 
every 4 cycles instead of 3 cycles.  If patients achieved CR, follow up radiological studies will continue every 3 
months for one year, then every six months for the next two years.

CR: 
 
1. Complete disappearance of all detectable clinical evidence of disease and disease-related symptoms if present before 

 
 
therapy.  
2a. Typically FDG-avid lymphoma: in patients with no pretreatment PET scan or when the PET scan was positive before 
therapy, a post-treatment residual mass of any size is permitted as long as it is PET negative.  
2b. Variably FDG-avid lymphomas/FDG avidity unknown: in patients without a pretreatment PET scan, or if a 
pretreatment PET scan was negative, all lymph nodes and nodal masses must have regressed on CT to normal size (  1.5 
cm in their greatest transverse diameter for nodes > 1.5 cm before therapy). Previously involved nodes that were 1.1 to 1.5 
cm in their long axis and more than 1.0 cm in their short axis before treatment must have decreased to 1.0 cm in their 
short axis after treatment.  
3. The spleen and/or liver, if considered enlarged before therapy on the basis of a physical examination or CT scan, should 
not be palpable on physical examination and should be considered normal size by imaging studies, and nodules related to 
lymphoma should disappear. However, determination of splenic involvement is not always reliable because a spleen 
considered normal in size may still contain lymphoma, whereas an enlarged spleen may reflect variations in anatomy, 
blood volume, the use of hematopoietic growth factors, or causes other than lymphoma.  
4. If the bone marrow was involved by lymphoma before treatment, the infiltrate must have cleared on repeat bone 
marrow biopsy. The biopsy sample on which this determination is made must be adequate (with a goal of > 20 mm 
unilateral core). If the sample is indeterminate by morphology, it should be negative by immunohistochemistry. A sample 
that is negative by immunohistochemistry but that demonstrates a small population of clonal lymphocytes by flow 
cytometry will be considered a CR until data become available demonstrating a clear difference in patient outcome.  
Cru 
 
The use of the above definition for CR and that below for PR eliminates the category of CRu.  
PR 
 
The designation of PR requires all of the following:  
1. At least a 50% decrease in sum of the product of the diameters (SPD) of up to six of the largest dominant nodes or 
nodal masses. These nodes or masses should be selected according to all of the following: they should be clearly 
measurable in at least 2 perpendicular dimensions; if possible they should be from disparate regions of the body; 
and they should include mediastinal and retroperitoneal areas of disease whenever these sites are involved.  
2. No increase should be observed in the size of other nodes, liver, or spleen.  
3. Splenic and hepatic nodules must regress by 50% in their SPD or, for single nodules, in the greatest transverse 
diameter.  
4. With the exception of splenic and hepatic nodules, involvement of other organs is usually assessable and no 
measurable disease should be present.  
5. Bone marrow assessment is irrelevant for determination of a PR if the sample was positive before treatment. 
However, if positive, the cell type should be specified (eg, large-cell lymphoma or small neoplastic B cells). 
Patients who achieve a CR by the above criteria, but who have persistent morphologic bone marrow involvement 
will be considered partial responders.  
When the bone marrow was involved before therapy and a clinical CR was achieved, but with no bone marrow 
assessment after treatment, patients should be considered partial responders.  
6. No new sites of disease should be observed.  

 
 
7. Typically FDG-avid lymphoma: for patients with no pretreatment PET scan or if the PET scan was positive before 
therapy, the post-treatment PET should be positive in at least one previously involved site.  
8. Variably FDG-avid lymphomas/FDG-avidity unknown: for patients without a pretreatment PET scan, or if a 
pretreatment PET scan was negative, CT criteria should be used.  
In patients with follicular lymphoma or mantle-cell lymphoma, a PET scan is only indicated with one or at most two 
residual masses that have regressed by more than 50% on CT; those with more than two residual lesions are unlikely to be 
PET negative and should be considered partial responders.  
 
Stable Disease 
 
Stable disease (SD) is defined as the following:  
1. A patient is considered to have SD when he or she fails to attain the criteria needed for a CR or PR, but does not 
fulfill those for progressive disease (see Relapsed Disease [after CR]/Progressive Disease [after PR, SD]).  
2. Typically FGD-avid lymphomas: the PET should be positive at prior sites of disease with no new areas of 
involvement on the post-treatment CT or PET.  
3. Variably FDG-avid lymphomas/FDG-avidity unknown: for patients without a pretreatment PET scan or if the 
pretreatment PET was negative, there must be no change in the size of the previous lesions on the post-treatment 
CT scan.  
 
Relapsed Disease (after CR)/Progressive Disease (after PR, SD) 
 
Lymph nodes should be considered abnormal if the long axis is more than 1.5 cm regardless of the short axis. If a lymph 
node has a long axis of 1.1 to 1.5 cm, it should only be considered abnormal if its short axis is more than 1.0. Lymph 
nodes 1.0 x 1.0 cm will not be considered as abnormal for relapse or progressive disease.  
1. Appearance of any new lesion more than 1.5 cm in any axis during or at the end of therapy, even if other lesions 
are decreasing in size. Increased FDG uptake in a previously unaffected site should only be considered relapsed or 
progressive disease after confirmation with other modalities. In patients with no prior history of pulmonary 
lymphoma, new lung nodules identified by CT are mostly benign. Thus, a therapeutic decision should not be made 
solely on the basis of the PET without histologic confirmation.  
2. At least a 50% increase from nadir in the SPD of any previously involved nodes, or in a single involved node, or 
the size of other lesions (eg, splenic or hepatic nodules). To be considered progressive disease, a lymph node with 
a diameter of the short axis of less than 1.0 cm must increase by 50% and to a size of 1.5 x 1.5 cm or more than 
1.5 cm in the long axis.  
3. At least a 50% increase in the longest diameter of any single previously identified node more than 1 cm in its short 
axis.  
4. Lesions should be PET positive if observed in a typical FDG-avid lymphoma or the lesion was PET positive 
before therapy unless the lesion is too small to be detected with current PET systems (< 1.5 cm in its long axis by 
CT).  
Measurable extranodal disease should be assessed in a manner similar to that for nodal disease. For these 
recommendations, the spleen is considered nodal disease. Disease that is only assessable (eg, pleural effusions, bone 
lesions) will be recorded as present or absent only, unless, while an abnormality is still noted by imaging studies or 
physical examination, it is found to be histologically negative.  
 
9. REGULATORY AND REPORTING REQUIREMENTS 

 
 
 
The descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events 
(CTCAE) version 3.0 will be utilized for adverse event reporting.  All appropriate treatment areas should have access 
to a copy of the CTCAE version 3.0.  A list of adverse events that have occurred or might occur (Comprehensive 
Adverse Events and Potential Risks list) can be found in Section 6 (Pharmaceutical Information).    A copy of the 
CTCAE version 3.0 can be downloaded from the CTEP web site (http://ctep.cancer.gov/reporting/ctc.html).   
 
9.1 
Expedited Adverse Event Reporting 
 
We agree to provide Merck (Attn: Worldwide Product Safety; FAX 215 993-1220) with copies of all 
serious adverse experiences within two working days. Additionally, we agree to report any pregnancy occurring 
in association with use of a Merck Product to Merck (Attn: Worldwide Product Safety; FAX 215 993-1220). A 
copy of all 15 Day Reports and Annual Progress Reports is submitted as required by FDA, European Union 
(EU), Pharmaceutical and Medical Devices agency (PMDA) or other local regulators by the investigator. We 
agree to cross reference this submission according to local regulations, to the Merck Investigational Compound 
number (IND, CSA, etc) at the time of submission. Additionally we agree to submit a copy of these reports to 
Merck (Attn: Worldwide Product Safety; FAX 215 993-1220) at the time of submission to the appropriate 
regulatory agency. 
Notes: 
* In studies involving human subjects, serious adverse experience means any experience that 
suggest a significant hazard, contraindication, side effect or precaution.  A serious adverse 
experience includes any experience that is fatal or immediately life threatening, results in a 
persistent or significant disability/incapacity, requires or prolongs in-patient hospitalization, 
or is a congenital anomaly, cancer, or overdose.  
 Other important medical events that may not result in death, not be life-threatening, or not 
require hospitalization may be considered a serious adverse experience when, based upon 
appropriate medical judgment, the event may jeopardize the subject/patient and may require 
medical or surgical intervention to prevent one of the outcomes listed previously.

9.2 Registration Guidelines 
 
 
 
 
Once the signed informed consent has been obtained and all pretreatment evaluations have been 
performed, patients will be entered on study.  To register a patient, the research nurse or data 
manager must complete the Eligibility Checklist and FAX a copy of this and the informed consent 
including the Bill of Rights to the Coordinator at the City of Hope (FAX #626-256-8654).  The

9.3 COH DSMB Data Reporting 
 
A) 
Definition of Risk Level 
 
This is a Risk Level 3 study, as defined in the “City of Hope Data and Safety 
Monitoring Plan”, http://www.coh.org/dsmc/Pages/forms-and-procedures.aspx 
because it is a Phase 2 clinical trial where the risks are at least balanced by the 
potential benefit to subjects and the importance of the knowledge that may result. 
 
 
B) 
Monitoring and Personnel Responsible for Monitoring 
 
The Protocol Management Team (PMT) consisting of the PI, Collaborating 
Investigator, CRA, protocol nurse, and statistician is responsible for monitoring the 
data and safety of this study, including implementation of any stopping rules for 
safety and efficacy.

Data and safety will be reported to the COH DSMC using the PMT report and 
submitted according to the timelines in Table 1 above.  Protocol specific data 
collection will include the following items:.  hematologic response and toxicities of 
treatment. 
 
 
C) Definitions 
 
Adverse event (AE) - An adverse event is any untoward medical experience or change of an existing 
condition that occurs during or after treatment, whether or not it is considered to be related to the 
protocol intervention.  

 
 
 
Unexpected Adverse Event [21 CFR 312.32 (a) – An adverse event is unexpected if it is not listed in 
the investigator’s brochure and/or package insert; is not listed at the specificity or severity that has 
been observed; is not consistent with the risk information described in the protocol and/or consent; is 
not an expected natural progression of any underlying disease, disorder, condition, or predisposed risk 
factor of the research participant experiencing the adverse event. 
 
Expected Adverse Event - Any event that does not meet the criteria for an unexpected event OR is an 
expected natural progression of any underlying disease, disorder, condition, or predisposed risk factor 
of the research participant experiencing the adverse event 
 
Serious Adverse Event (SAE) [21 CFR 312.32] is defined as any expected or unexpected adverse 
event that results in any of the following outcomes: 
 Death 
 Is life-threatening experience (places the subject at immediate risk of death from the event as it 
occurred) 
 Unplanned hospitalization (equal to or greater than 24 hours) or prolongation of existing 
hospitalization 
 A persistent or significant disability/incapacity 
 A congenital anomaly/birth defect 
 Secondary Malignancy 
 Any other adverse event that, based upon appropriate medical judgment, may jeopardize the 
subject’s health and may require medical or surgical intervention to prevent one of the 
outcomes listed above (examples of such events include allergic bronchospasm requiring 
intensive treatment in the emergency room or at home, blood dyscrasisas of convulsions that 
do not result in inpatient hospitalization, or the development of drug dependency or drug 
abuse). 
 
Unanticipated problem (UP) – Any incident, experience, or outcome that meets all three of the 
following criteria: 
1. Unexpected (in term nature, severity, or frequency) given the following: a) the research procedures 
described in the protocol-related documents such as the IRB approved research protocol, informed 
consent document or Investigator Brochure (IB); and b) the characteristics of the subject 
population being studied; AND 
2. Related or possibly related to participation in the research (possibly related means there is a 
reasonable possibility that the incident, experience, or outcomes may have been caused by the 
drugs, devices or procedures involved in the research); AND 
3. Suggests that the research places subjects or others at greater risk of harm (including physical, 
psychological, economic, or social harm) than previously known or recognized. 
 
 
D. 
Reporting of Unanticipated Problems and Adverse Events 
 
Unanticipated Problems: Most unanticipated problems must be reported to the COH DSMC and IRB 
within 5 calendar days according to definitions and guidelines at 

 
 
http://www.coh.org/hrpp/Pages/hrpp-policies.aspx.  Any unanticipated problem that occurs during the 
study conduct will be reported to the DSMC and IRB by submitting electronically in iRIS 
(http://iris.coh.org). 
 
Serious Adverse Events - All SAEs occurring during this study, whether observed by the physician, 
nurse, or reported by the patient, will be reported according to definitions and guidelines at 
http://www.coh.org/hrpp/Pages/hrpp-policies.aspx and Table 2 below.  Those SAEs that require 
expedited reporting will be submitted electronically in iRIS (http://iris.coh.org/). 
 
Adverse Events - Adverse events will be monitored by the PMT.  Adverse events that do not meet the 
criteria of serious OR are not unanticipated problems will be reported only in the protocol 
continuation reports and PMT report (see Table 2 below).

information is obtained the data manager will complete the Response/Off-
Study Follow-Up Form. 
 
10. STATISTICAL CONSIDERATIONS 
 
10.1 
Study Design/Endpoints 
  
Response rate (CR+PR) will be the primary endpoint.  An underlying 20% response rate will be regarded as 
not sufficiently active, and the trial is designed to have little chance of missing a 40% response rate.  A two-
stage design will be used. In the first stage, 17 patients will be enrolled.  If 4 or more respond, accrual will 
continue to a total of 33 patients, with 10 or more responses regarded as evidence of sufficient activity to 
warrant further investigation.    If the true response rate is 20%, the proposed design has a 90% chance of 
declaring vorinostat plus rituximab insufficiently active, and a 55% chance of stopping early.  If the true 
response rate is 40%, there is a 89% chance of concluding VORINOSTAT is sufficiently active.  All 
patients beginning VORINOSTAT therapy will be included in response rates calculations, which will 
include exact binomial confidence intervals. 
  
All reportable adverse events will be monitored by the PI and CRA, and reported as described in section 
10. Reportable and non-reportable adverse events are routinely tabulated for phase II consortium trials 
as the reports arrive. The time to progression and overall survival will be estimated using the product-
limit method of Kaplan and Meier. Toxicity information recorded will include the type, severity, time of 
onset, time of resolution, and the probable association with the study regimen. Tables will be 
constructed to summarize the observed incidence by severity and type of toxicity.  Baseline information 
(e.g. the extent of prior therapy, extent of disease) and demographic information will be presented, as 
well, to describe the patients treated in this Phase II study.   
 
10.2 
Sample Size/Accrual Rate 
 
Estimated monthly accrual: 3 patients  
Proposed sample size: 17 to 33 patients as outlined in section 11.1 
 
10.3 
Stratification Factors 
 
 
 
None planned. 
 
10.4 
Reporting and Exclusions 
 

 
 
10.5 
Evaluation of toxicity.  All patients will be evaluable for toxicity from the time of their first 
treatment  with vorinostat. 
 
10.5.1 Evaluation of response.  All patients included in the study must be assessed for 
response to treatment, even if there are major protocol treatment deviations or if they are 
ineligible.  Each patient will be assigned one of the following categories:  complete response, 
partial response, stable disease, progressive disease, early death from malignant disease, 
early death from toxicity, early death because of other cause, or unknown (not assessable, 
insufficient data).   
 
All of the patients who met the eligibility criteria (with the possible exception of those who 
received no study medication) will be included in the main analysis of the response rate.  
Patients in any response categories other than complete response, partial response or stable 
disease will be considered as failing to respond to treatment (disease progression).  Thus, an 
incorrect treatment schedule or drug administration does not result in exclusion from the 
analysis of the response rate.   
 
All conclusions will be based on all eligible patients, with possible exploratory analysis of  
subset of patients in the event of early death due to other reasons, early discontinuation of 
treatment, major protocol violations, or similar circumstances requiring an assessment of the 
sensitivity of results.  However, such subanalyses may not serve as the basis for drawing 
conclusions concerning treatment efficacy, and the reasons for excluding patients from the 
analysis will be clearly reported.  Exact binomial 95% confidence intervals will be provided 
for response rates.  
 
11. Correlative Studies:  
 
Cytokine analysis 
 
We have recently demonstrated (Li, et al PNAS, 2008) that  even low doses of vorinostat dramatically 
decrease pro-inflammatory cytokines such as IL-2, IFN-, TNF-, and IL-6. This suppression of 
cytokines may be of importance to the clinical effect of histone deacetylase inhibition on symptoms such 
as itching or the B symptoms of lymphoma, as well as potentially impacting upon lymphoma growth. 
 
The effects of treatment on systemic levels of immune cytokines will be evaluated by cytokine bead 
array analysis using Luminex X-MAP bead array technology.  This technology platform allows for the 
simultaneous measurement and quantification of multiple cytokines and other secreted factors from very 
small (10-50 l) samples.  This analysis is sensitive (generally single pictogram level), reproducible, and 
accurate.  The Clinical Immunobiology Correlative Studies Laboratory (CICSL) at COH is equipped 
with two Bioplex HTF units for these analyses.   
 
 
Preassembled multiplex panels are available commercially that allow for the simultaneous evaluation of 
the following 30 pro- and anti-inflammatory cytokine and immune factors: 
IL-1β, IL-1RA, IL-2, IL-2R, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12p40/p70, IL-13, IL-15, IL-17, 
TNF-α, IFN-α, IFN-γ, GM-CSF, MIP-1α, MIP-1β, IP-10, MIG, Eotaxin, RANTES, MCP-1, VEGF, G-

 
 
CSF, EGF, FGF-basic, and HGF. 
For these analyses, 2 ml peripheral blood will be collected prior to starting therapy, and on day 14. 
Whole blood will be collected in red-top tubes (Becton Dickinson) that are completely free of anti-
coagulant reagents.  Sample tubes should be set in an upright position at room temperature may be 
processed for up to 24 hours. 
 
To process serum:   
 
i. Allow whole blood samples to clot for 1 – 2 hours at room temperature.  
ii. Centrifuge at 1000 x g at 4°C for 15 minutes, max brake.  
iii. Using a micropipettor, collect the serum without disturbing the red cell pellet at the 
bottom of the tube and transfer to a flip-top microfuge tube or a 15-mL centrifuge 
tube (depending on the total volume).    
iv. Freeze and store at -80oC  in 100 ìL aliquots.   
  
 
Luminex analysis on serum samples will be performed in bulk.  Each sample will be evaluated in 
duplicate with the average value recorded.  Quantitative values will only be determined for samples with 
values that fall within the 80% observed/expected range for the standard curve. 
 
Samples should be sent to:

A Phase II Study of Suberoylanilide Hydroxamic Acid (VORINOSTAT) (NSC 701852) plus Rituximab in Indolent 
Non-Hodgkin’s Lymphoma 
 
 
This is a clinical trial, a type of research study.  Your study doctor will explain the clinical trial to you.   Clinical trials 
include only people who choose to take part. Please take your time to make your decision about taking part.  You may 
discuss your decision with your friends and family.  You can also discuss it with your health care team.  If you have any 
questions, you can ask your study doctor for more explanation.  
 
You are being asked to take part in this study because you have slow growing Non-Hodgkin’s Lymphoma (NHL) or low-
grade lymphoma that has returned.  
 
Why is this study being done? 
 
The purpose of this study is to find out what effects, good and/or bad, vorinostat (Suberoylanilide Hydroxamic Acid 
(VORINOSTAT)) plus rituximab has on you and your lymphoma.  
 
This research is being done because lymphoma responds initially to chemotherapy but usually comes back within 5 years. 
The disease free interval between treatments becomes shorter and shorter.  Better and new methods of therapy are needed 
to treat low-grade lymphoma. 
 
How many people will take part in the study? 
 
About 37 people will take part in this study.   
 
What will happen if I take part in this research study?   
 
Treatment: 
 
If you are eligible and decide to take part in this treatment, you will take a drug called vorinostat, an drug approved by the 
Food and Drug Administration (FDA) in a different type of lymphoma, but experimental in this form of lymphoma.  
VORINOSTAT is an oral drug that will be given to you in capsule form that you will take by mouth two times a day, 
every day for two weeks followed by one week of rest (no drug).  Each 3 weeks, or 21 days, is considered one cycle of 
therapy.  You will continue to take VORINOSTAT for a total of 12 cycles or until your cancer begins to grow or you 
have side effects that are unmanageable. You will also receive a drug called rituximab, which is FDA approved for 
treatment of this type of lymphoma. 
 
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 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.  This will be up to your study doctor. 

 
 
 
 
Medical history and physical examination 
 
Blood tests (about one tablespoon of blood) to look at the cellular and chemical make up of your blood  
 
Scans and/or X-rays to evaluate the extent of your disease 
 
You will also have your bone marrow examined (called "bone marrow aspiration and biopsy") at the start 
of this study, and at the end of the treatment period if the first bone marrow test indicates presence of 
lymphoma.  Your skin over your hipbone will be numbed by a shot of local anesthetic (lidocaine) given 
just under your skin.  A needle will be inserted through the numbed skin and into the hipbone.  The bone 
marrow will be removed by using suction and a twisting motion of the needle.  You may feel pain, and 
minor infection is also possible.  Rarely allergic reactions to the anesthetic may occur.  These are routine 
tests for many patients with lymphoma.  The bone marrow will be looked at to find out if any lymphoma 
cells are present.  This will be repeated every 3 cycles. 
 
During the study …  
 
If the exams, tests and procedures show that you can be in the study, and you choose to take part, then you will need the 
following tests and procedures.  They are part of regular cancer care.  
 
You will be asked to keep track of your study medication by recording the date and time you take the study medication, 
any symptoms you experience and any questions you may have in a study diary.  You will be asked to bring the study 
diary with you each time you come in to see your doctor.   
 
 
Physical examinations every week for the first cycle, and every three weeks after that 
 
Blood tests every week for the first four weeks, and every three weeks after that (appropriate amount of 
blood collected per test will be 2 - 3 teaspoons) 
 
Scans and/or X-rays every nine weeks  
 
If your tumor shrinks and stays that way for 2 sets of scans, you may be able to go 12 weeks between 
scans 
 
When I am finished taking VORINOSTAT: 
 
After you complete treatment, your medical condition will be followed until your disease returns. 
 
Study Chart 
 
You will receive VORINOSTAT twice a day every day for 14 days in this study followed by a 7 day rest period. This 21 day 
period of time is called a cycle.  The cycle will be repeated up to 12 times.  Each cycle is numbered in order.  The chart below 
shows what will happen to you during Cycle 1 and future treatment cycles as explained previously.  The left-hand column 
shows the day in the cycle and the right-hand column tells you what to do on that day.

 
Return to your doctor’s office for your next exam and to begin the next cycle. 
 
How long will I be in the study? 
 
You will be asked to take VORINOSTAT plus rituximab for up to 12 cycles (36 weeks) or until your disease worsens, or 
you have unmanageable side effects.  After you are finished taking VORINOSTAT, the study doctor will keep track of 
your medical condition until your disease returns. 
 
 
Can I stop being in the study? 
 
Yes.  You can decide to stop at any time.  Tell the study doctor if you are thinking about stopping or decide to stop.  He or 
she will tell you how to stop safely.  
 
It is important to tell the study doctor if you are thinking about stopping so any risks from the VORINOSTAT 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. 
 
The study doctor may stop you from taking part in this study at any time if he/she believes it is in your best interest; if you 
do not follow the study rules; or if the study is stopped. 
 
What side effects or risks can I expect from being in the study?  
 
You may have side effects while on the study.  Everyone taking part in the study will be watched carefully for any side 
effects.  However, doctors don’t know all the side effects that may happen.  Side effects may be mild or very serious. 
Your health care team may give you medicines to help lessen side effects. Many side effects go away soon after you stop 
taking the VORINOSTAT. In some cases, side effects can be serious, long lasting, or may never go away.  
 

 
 
You should talk to your study doctor about any side effects that you have while taking part in the study.    
 
Risks and side effects related to the VORINOSTAT include those which are: 
 
Likely 
 
 
Nausea, which is temporary and may require additional medication 
 
Diarrhea, which is temporary and may require additional medication and/or a delay in your treatment 
 
Anemia: (low red blood cell count), which may make you feel tired and short of breath. If this happens, you may 
be started on a drug to increase your red blood cell count. Severe anemia may require a transfusion of red blood 
cells 
 
Decreased platelet count, which increases the risk of easy bleeding and/or bruising. This could result in the need 
for a platelet transfusion. 
 
Fatigue, which is temporary and should get better when treatment is stopped 
 
Loss of appetite, which is temporary and should get better when treatment is stopped 
 
 
 
High creatinine, which is temporary, seen on blood tests and is without symptoms. It should return to normal 
when treatment is stopped. 
 
High blood sugar, which is temporary and may require additional medication. 
 
Neutropenia,  
 
Weight loss,  
 
Vomiting, which is temporary and may require additional medication 
 
 Less Likely   
 
 
Changes in taste, which is temporary and should get better when treatment is stopped 
 
Low blood calcium, which is temporary and may require additional medication 
 
Low potassium, which is temporary, seen on blood tests and may require potassium supplements 
 
Abdominal pain, which is temporary and may require additional medication 
 
Low lymphocyte counts, a change in the number of lymphocytes in the blood, which doesn’t cause symptoms, is 
temporary and should get better when treatment is stopped. 
 
Prolonged QTc interval, which may cause increased risk for heart rhythm changes, which is temporary and 
should resolve when drug is stopped. 
 
Increased INR, which implies increased blocking of blood clotting when on coumadin, this may require decrease 
of your coumadin therapy and more frequent monitoring of your clotting profile. 
 
Fever,  in the absence of low white blood counts or other signs of infection. If caused by the drug, it should go 
away when drug is stopped. 
 
Shakes and chills, which is temporary and should go away when drug is stopped.  
 
Hair loss, which is temporary and tends to stop over time. 
 
Constipation, which is temporary and can be treated with standard anti-constipation medicines.

 
Heartburn, or a feeling of “stomach ache”, which is temporary and can be treated with standard heartburn 
medications. 
 
Increased risk of infection, even with normal blood counts, which may be related to the drug’s effect on immune 
cells, which are defective already in lymphoma. 
 
Edema, swelling of the lower limbs, which is temporary and should go away when drug is stopped. 
 
Changes in  liver function tests (AST, ALT, , Alkaline Phosphatase, Bilirubin) which are temporary and 
should go away when drug is stopped.

 
Cough, which is temporary and should resolve when drug is stopped 
 
Shortness of breath, which is temporary and should resolve when drug is stopped. 
 
Blood clots, which may appear in the legs or lungs, and would necessitate further medical therapy such as anti-
clotting medicines.  
 
Hypermagnesemia, 
 
Hypophosphatemia, 
 
Hyponatremia, 
 
Dizziness 
 
Sensory neuropathy, 
 
Dehydration, which is temporary and may require additional fluids, either by mouth or by IV (intravenous,

The following side effects have been reported by subjects on other studies with VORINOSTAT, but the 
relationship to VORINOSTAT is not known 
 
ALLERGY/IMMUNOLOGY – vasculitis- swelling around blood vessels which should resolve with stopping the drug 
if not due to underlying disease. 
CARDIAC ARRHYTHMIA - atrial fibrillation; palpitations; ventricular fibrillation- serious heart beat changes 
which may require additional medications. 
CARDIAC GENERAL - cardiac ischemia/infarction- “heart attacks”, which may be serious and require further 
medical treatment; hypertension; hypotension- changes in blood pressure which may require additional medicines for 
control, and should resolve with stopping drug if not related to underlying disease. 
COAGULATION – PTT- changes in blood clotting profile which may return to normal after stopping drug. 
CONSTITUTIONAL SYMPTOMS – insomnia- sleeplessness; sweating- both of which may be temporary and 
disappear with stopping of medication if not due to underlying disease. 
DEATH – unexplained death of uncertain relationship to study drug 
DERMATOLOGY/SKIN –nail changes; pruritus- itching; rash- these changes may disappear with stopping of drug; 
ecchymosis- bleeding into skin, which should heal over time. 
GASTROINTESTINAL – dysphagia- difficulty in swallowing; esophagitis- pain upon swallowing; flatulence- excess 
gas; gastritis- burning sensation in the stomach; mucositis/stomatitis- pain due to changes in the cells lining the mouth 
and throat; all of these should improve with stopping the drug. 
HEMORRHAGE/BLEEDING – epistaxis-nosebleed; hematuria- blood in the urine; hemoptysis- bloody cough; 
petechiae-tiny bleeds in the skin. These may improve when drug is stopped if not related to the underlying disease. 
INFECTION – infection – these may require the addition of further medications such as antibiotics. 
METABOLIC/LABORATORY – hypercalcemia- high blood levels of calcium, which may require additional 
medications; hyperkalemia- high blood levels of potassium, treated with additional medications; hypernatremia- high 
blood sodium, usually treated with intravenous fluid; hypoglycemia- low blood sugar treated with sugar supplements; 
hypomagnesemia- low blood magnesium, treated with magnesium supplements; proteinuria- protein in the urine, which 
may resolve with stopping of the drug.  
MUSCULOSKELETAL/SOFT TISSUE - gait/walking- changes in ability to walk which may get better with stopping 
of drug if not related to the underlying disease.  
NEUROLOGY – confusion- which may resolve with stopping of drug if not related to underlying disease. 
PAIN - back pain; chest/thorax pain; flank pain; gingival (gum) pain; joint pain; limb pain; muscle pain; 
pharyngolaryngeal pain- all these may disappear with stopping of drug if not due to underlying disease.  
PULMONARY/UPPER RESPIRATORY - sinus congestion- may resolve with stopping of drug if not due to 
underlying disease. 

 
 
RENAL/GENITOURINARY – urinary incontinence; urinary retention- difficulty controlling urination or difficulty 
in passing urine, both may disappear with stopping drug if not due to underlying disease. 
VASCULAR - deep vein thrombosis- blood clots in the arms, legs, or lungs, which may require anti-clotting 
medications for prevention of further abnormal clots.  
 
 
Biopsy and blood tests: The biopsies and blood tests that will be done as a part of this study may cause pain at the site 
where the needle enters the skin, bleeding, or infection.  Pain lasting several days may also result after the biopsies.  This 
side effect may be treated with pain medication. 
 
Bone Marrow Aspiration and Biopsy: The local anesthesia used to numb the hip area may initially cause a burning 
sensation in the skin and bone surface lasting several seconds.  During the actual procedure, you may temporarily feel 
pressure and/or pain of varying degrees.  If necessary, you may ask your physician for additional local anesthesia or a 
medication to ease your stress.  After the procedure is completed, you may bleed, have a bruise, and may experience 
soreness in the area for a few days.  Rarely an infection can develop. 
 
Reproductive risks:  You should not become pregnant or father a baby while on this study because the drugs in this 
study can affect an unborn baby.  Women should not breastfeed a baby while on this study.  It is important you 
understand that you need to use birth control while on this study.  Check with your study doctor about what kind of birth 
control methods to use and how long to use them.  Some methods might not be approved for use in this study.  
 
For more information about risks and side effects, ask your study doctor. 
 
Are there benefits to taking part in the study? 
 
Taking part in this study may or may not make your health better.  While doctors hope VORINOSTAT will be more 
useful against cancer compared to the usual treatment, there is no proof of this yet. We do know that the information from 
this study will help doctors learn more about VORINOSTAT as a treatment for cancer.  This information could help 
future cancer patients. 
 
What other choices do I have if I do not take part in this study? 
 
Your other choices may include: 
 
 
Getting treatment or care for your cancer without being in a study, including other chemotherapy, 
 
Taking part in another study 
 
Getting no treatment 
 
Getting comfort care, also called palliative care.  This type of care helps reduce pain, tiredness, appetite problems 
and other problems caused by the cancer.  It does not treat the cancer directly, but instead tries to improve how 
you feel.  Comfort care tries to keep you as active and comfortable as possible.   
 
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?

Adapted from Lacy et al. “Drug Information Handbook”, 12th edition, 2004  
 
1   Substrates 
Yes (Y): Enzyme plays a clinically significant role (≥ 30%) in drug metabolism.  Therefore, competitive inhibition 
may occur resulting in increased serum levels of the drug and/or study agent.  
 No (N): Enzyme plays clinically insignificant role (<30%) in drug metabolism.  Therefore, competitive inhibition 
is unlikely to occur.  

 
 
 
 
 
 
 
2 Inhibitors 
Degree of inhibition was determined by evaluating Ki values set in a ratio with achievable serum drug 
concentrations under normal dosing conditions (Cmax).  The following parameters for predicting clinical relevance of 
competitive CYP inhibition were employed:  
+++:  likely, Cmax/Ki ≥ 1. Clinically relevant inhibition will likely result in increased serum levels of the study 
agent.  
++:  possible, Cmax/Ki=0.1-1. Clinically relevant inhibition may possibly result in increased serum levels of the 
study agent. 
±:  
remote, Cmax/Ki<0.1. 
Clinically relevant inhibition is remotely possible.  
 
3 Inducers 
Yes (Y): Enzyme was effectively induced by drug.  Therefore, lowered serum levels of the study agent may occur.  
No (N): Enzyme was not effectively induced by drug. Therefore, serum levels of the study agent are not expected to 
be altered.
