Conditions: Pheochromocytoma Paraganglioma
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 39
Healthy volunteers: no

Brief summary:
Pheochromocytoma is a rare, catecholamine (ex. adrenaline) secreting tumor that requires preoperative alpha blockade to minimize intraoperative hemodynamic instability, thereby reducing intra- and postoperative morbidity and mortality. Phenoxybenzamine is a non-selective alpha blocker that is significantly more expensive and is associated with increased adverse effects in comparison with selective alpha blockers such as doxazosin. Retrospective studies show minimal differences in hemodynamic instability and no differences in postoperative morbidity and mortality between selective vs. non-selective alpha blockers. This study is a randomized controlled trial that will compare hemodynamic instability, morbidity, mortality, cost, and quality of life between patients blocked with phenoxybenzamine vs. doxazosin.

Detailed description:
Pheochromocytoma is a catecholamine (ex. adrenaline) secreting tumor for which the primary treatment is surgical resection. Due to the hormones secreted by the tumor, alpha receptors on peripheral blood vessels are activated, causing constriction of these blood vessels and dangerously high blood pressure. During resection of the tumor, the source of excess hormone secretion is abruptly removed, which can lead to life-threatening blood pressure fluctuations during surgery.

Alpha blockers are a class of medication that blocks the alpha receptor on blood vessels. Given preoperatively over a few weeks, these medications negate the effects of the excess hormones secreted by the pheochromocytoma, reducing the frequency and severity of dangerous blood pressure fluctuations intraoperatively and postoperatively. Preoperative alpha blockade is therefore critical to safely perform surgery to resect pheochromocytoma.

Phenoxybenzamine, a non-selective alpha blocker, is the most common medication used to alpha block patients prior to pheochromocytoma resection. However, due to increasing drug costs and increased side effects in comparison with selective alpha blockers, there is a renewed interest in studying alternatives to phenoxybenzamine.

Selective alpha blockers such as doxazosin are also commonly used to alpha block patients prior to pheochromocytoma resection. Selective alpha blockers are significantly less expensive and are associated with fewer side effects than phenoxybenzamine. Most retrospective studies comparing phenoxybenzamine with selective alpha blockers show no difference in intraoperative blood pressure fluctuations, morbidity, or mortality in pheochromocytoma resection. However, no prospective, randomized controlled trials comparing phenoxybenzamine to selective alpha blockers have been performed.

The purpose of our study is to analyze preoperative, intraoperative, and postoperative outcomes in patients randomized to receive phenoxybenzamine (non-selective) or doxazosin (selective) for alpha blockade prior to pheochromocytoma resection. Outcomes will include postoperative morbidity and mortality, intraoperative hemodynamic instability, quality of life, and cost.

Arms:
arm 1: 3-4 weeks prior to date of surgery, patient will start phenoxybenzamine 10mg PO twice daily. Phenoxybenzamine will then be titrated to a blood pressure \<120/80 (sitting) with mild orthostatic hypotension (drop in systolic blood pressure by 20 points or diastolic blood pressure by 10 points from sitting to standing position); systolic blood pressure not less than 90 (standing). arm 2: 3-4 weeks prior to date of surgery, patient will start doxazosin 1 mg PO daily. Phenoxybenzamine will then be titrated to a blood pressure \<120/80 (sitting) with mild orthostatic hypotension (drop in systolic blood pressure by 20 points or diastolic blood pressure by 10 points from sitting to standing position); systolic blood pressure not less than 90 (standing).

Interventions: intervention 1: Phenoxybenzamine intervention 2: Doxazosin
Intervention descriptions: intervention 1: Non-selective alpha blocker intervention 2: Selective alpha blocker

Pheochromocytoma is a catecholamine (ex. adrenaline) secreting tumor for which the primary treatment is surgical resection. Due to the hormones
secreted by the tumor, alpha receptors on peripheral blood vessels are activated, causing constriction of these blood vessels and dangerously high
blood pressure. During resection of the tumor, the source of excess hormone secretion is abruptly removed, which can lead to life-threatening
blood pressure fluctuations during surgery.
Alpha blockers are a class of medication that blocks the alpha receptor on blood vessels. Given preoperatively over a few weeks, these
medications negate the effects of the excess hormones secreted by the pheochromocytoma, reducing the frequency and severity of dangerous
blood pressure fluctuations intraoperatively and postoperatively. Preoperative alpha blockade is therefore critical to safely perform surgery to resect
pheochromocytoma.
Phenoxybenzamine, a non-selective alpha blocker, is the most common medication used to alpha block patients prior to pheochromocytoma
resection. However, due to increasing drug costs and increased side effects in comparison with selective alpha blockers, there is a renewed
interest in studying alternatives to phenoxybenzamine.
Selective alpha blockers such as doxazosin are also commonly used to alpha block patients prior to pheochromocytoma resection. Selective alpha
blockers are significantly less expensive and are associated with fewer side effects than phenoxybenzamine. Most retrospective studies comparing
phenoxybenzamine with selective alpha blockers show no difference in intraoperative blood pressure fluctuations, morbidity, or mortality in
pheochromocytoma resection.
The purpose of our study is to analyze preoperative, intraoperative, and postoperative outcomes in patients undergoing pheochromocytoma
resection. We will compare a prospective group of patients who receive doxazosin (selective) for alpha blockade prior to surgery to a retrospective
group of patients who received phenoxybenzamine (non-selective). Outcomes will include postoperative morbidity and mortality, intraoperative
hemodynamic instability, quality of life, and cost.

If all of your research activities are without direct contact with study participants, provide the following information:
Indicate the purpose of the research, specifying the
problems and/or hypotheses to be addressed:
The purpose of our study is to analyze preoperative,
intraoperative, and postoperative outcomes in patients treated
with selective (doxazosin) or non-selective (phenoxybenzamine)
alpha blockade prior to pheochromocytoma resection. Outcomes
will include postoperative morbidity and mortality, intraoperative
hemodynamic instability, quality of life, and cost.
We hypothesize that doxazosin is not inferior compared to
phenoxybenzamine in terms of postoperative morbidity and
mortality, intraoperative hemodynamic instability, quality of life,
and cost.
Describe the study design and proposed data analyses:
Given the difficulty in randomizing patients (high cost of
phenoxybenzamine has caused a large portion of patients
crossing over to the doxazosin arm, resulting in unbalance
between the number of patients in each arm), patients who have
been pre-treated with doxazosin before pheochromocytoma
resection prospectively followed during the course of this study
will be compared to a retrospective group of patients who were
pre-treated with phenoxybenzamine.
Descriptive statistics including mean, median, standard
difference, and frequencies will be calculated for each of the
variables measured.
Differences in hemodynamic instability as indexed by specific vital
sign parameters, ICU length of stay, inpatient length of stay,
morbidity, mortality, cost, and quality of life will be analyzed with t
tests or non-parametric tests as appropriate.

*Specific Aims: Indicate the purpose of the research, specifying the problems and/or hypotheses to be addressed.
The purpose of our study is to analyze preoperative, intraoperative, and postoperative outcomes in patients treated with selective (doxazosin) or
non-selective (phenoxybenzamine) alpha blockade prior to pheochromocytoma resection. Outcomes will include postoperative morbidity and
mortality, intraoperative hemodynamic instability, quality of life, and cost.
3.0
*Background and Significance: Provide a summary of the background for this study and explain how it will
contribute to existing knowledge. 
For greater than minimal risk biomedical studies, include preliminary data.  If necessary, attach in Item 1.0 graphs
or tables used to convey information.  If there no preliminary data are available, briefly indicate why this proposed
study is a reasonable starting point.
Pheochromocytoma is a catecholamine (ex. adrenaline) secreting tumor for which the primary treatment is surgical resection. Due to the hormones
secreted by the tumor, alpha receptors on peripheral blood vessels are activated, causing constriction of these blood vessels and dangerously high
blood pressure. During resection of the tumor, the source of excess hormone secretion is abruptly removed, which can lead to life-threatening low
blood pressure in the absence of preoperative alpha blockade.
Alpha blockers are a class of drug that blocks the alpha receptor on blood vessels. Given preoperatively over a few weeks, these drugs negate the
effects of the excess hormones secreted by the pheochromocytoma, reducing the frequency and severity of dangerous blood pressure fluctuations
intraoperatively and postoperatively. Preoperative alpha blockade is therefore critical to safely perform surgery to resect pheochromocytoma.
Phenoxybenzamine, a non-selective alpha blocker, is the most commonly used drug used to alpha block patients prior to pheochromocytoma
resection. However, due to increasing drug costs and increased side effects in comparison with selective alpha blockers, there is a renewed
interest in studying alternatives to phenoxybenzamine.
Selective alpha blockers such as doxazosin are also commonly used to alpha block patients prior to pheochromocytoma resection. Retrospective
studies comparing phenoxybenzamine with selective alpha blockers suggest that the use of selective alpha blockers does not lead to additional
morbidity or mortality in pheochromocytoma resection. However, no prospective, randomized controlled trials comparing phenoxybenzamine to
selective alpha blockers have been performed.
Our study to our knowledge will represent the first prospective, randomized controlled trial comparing selective and non-selective alpha blockade in
resection of pheochromocytoma.
4.0
*Research Design and Methods: Describe in detail the design and methodology of the study.
PATIENT ACQUISITION. All patients referred to the UCLA Department of Surgery requiring surgical resection of pheochromocytoma or
paraganglioma will be counseled about surgery and the necessity for preoperative alpha blockade. The benefits and risks of the study will
discussed, and the patient will be given the opportunity to enroll. Upon obtaining informed consent regarding enrollment in the study, the patient will
be randomized to either receive preoperative blockade with either phenoxybenzamine or doxazosin.
PREOPERATIVE PREPARATION. The patient will then be referred to the UCLA Preoperative Evaluation and Planning Center (PEPC) for
preoperative planning and optimization by an attending anesthesiologist. Additional testing such as echocardiography or stress testing will be
pursed in accordance with preoperative risk-stratification in the standard fashion. A few weeks prior to surgery, the patient will initiate preoperative
alpha blockade with the drug as determined by randomization. The drug will be titrated to a blood pressure of 120-130/80-85 in the standard
fashion. Adjunctive beta blockers or calcium channel blockers may be initiated at the discretion of the physician.
Titration will be performed utilized the attached log ("Medication and Blood Pressure Log"), which will be emailed to the patient and will be returned
by the patient by email every 2 days. The patients sitting and standing blood pressure will be used to titrate their alpha blocker dosage to pre-
specified targets as noted in the original IRB proposal. Heart rate will be logged to determine whether the patient requires adjunctive

specified targets as noted in the original IRB proposal. Heart rate will be logged to determine whether the patient requires adjunctive
antihypertensive medications such as beta blockers or calcium channel blockers. This titration will take place over a period of 2-3 weeks. Once the
patient's alpha blockade titration is complete, the log will be saved in a secure, encrypted server and will be linked with the patients record using
non-identifying record ID.
INTRAOPERATIVE PROTOCOL. Intraoperative hemodynamic monitoring will be conducted in the standard fashion, and a phenylephrine dose
response curve will be generated by titration with phenylephrine to estimate the ED30 and therefore the effectiveness of the blockade. Surgery will
proceed in the standard fashion. Times of induction, tumor manipulation, and adrenal vein ligation will be recorded. Vasopressors will be used at
the discretion of the anesthesiologist.
POSTOPERATIVE PROTOCOL. Patients will be taken to the PACU for routine postoperative care. Admission to the surgical ICU will be performed
at the discretion of the attending anesthesiologist and surgeon.
QUALITY OF LIFE / DRUG ADVERSE EFFECTS. Data regarding patient health related quality of life and drug adverse effects will be collected at
five time points pre-blockade, post-blockade, and postoperatively at 3 months, 6 months, and 1 year. Health related quality of life data will be
assessed utilizing the Short Form-36. Patients will be queried to specific adverse effects such as nasal congestion, headaches, palpitation, as well
as their frequency and level of distress caused. Surveys will be complete in person during routine encounters or over the phone.
COST. Preoperative drug costs will be determined using the average wholesale price per unit multiplied by the number of units taken by the
patient. Enrollment of the patient in Medicare and Medicare part D will be noted. Data regarding out of pocket drug costs will be collected. Inpatient
costs will be calculated utilizing patient charges and the application of a charge to cost ratio.

Risks & Benefits
Benefits
1.0
*Are there any potential direct benefits (physical, psychological, social or other) to study participants? 
Yes
No
If yes, describe.
2.0
*Describe the potential benefits to society including the importance of the knowledge to be gained.
Currently, the evidence regarding selective vs. non-selective alpha blockade prior to pheochromocytoma resection is based retrospective data. No
prospective, randomized controlled trials have been performed. The potential benefits to society of a prospective, randomized controlled trial of
selective vs. non-selective alpha blockade prior to pheochromocytoma resection include those related to patient cost and quality of life.
(1) Cost. The cost of prescription drugs in the United States is increasing, with the cost of some drugs increasing by over 1000% in the last
decade.[1] Currently, the maximum listed wholesale price per unit of phenoxybenzamine is $197.79 in contrast to $1.42 for doxazosin[2]. In our
anecdotal experience, an increasing number of patients are unable to afford phenoxybenzamine for preoperative alpha blockade prior to
pheochromocytoma resection. As current studies show no differences in morbidity and mortality between selective and non-selective alpha
blockade prior to pheochromocytoma resection, doxazosin is likely to represent a clinically equivalent option associated with significant cost
savings.
(2) Quality of life. Phenoxybenzamine is a long-acting, non-competitive, non-selective alpha blocker that crosses the blood brain barrier, causing
centrally mediated side effects including headaches and sedation that limit the medication's tolerability. Patients who receive doxazosin in
comparison to phenoxybenzamine prior to pheochromocytoma resection less frequently experience postural hypotension, nasal stuffiness, and
headache.[3] In addition to being cost effective, doxazosin may also be associated with increased health related quality of life while receiving alpha
blockade.
Overall, current retrospective data suggest that selective alpha blockade is as effective as non-selective blockade in addition to being less costly
and associated with less frequent adverse effects. A randomized controlled trial demonstrating this will result in societal cost savings and increased
health related quality of life in patients undergoing pheochromocytoma resection.

Risks
3.0
*Indicate the potential risks/discomforts, if any, associated with each intervention or research procedure.
Additionally discuss any measures that will be taken to minimize risks.  If data are available, estimate (a) the
probability that a given harm may occur, (b) its severity, and (c) its potential reversibility.  The information
provided should be reflected in risks section of the informed consent documents.
If this is an exempt study and there are no risks, indicate N/A.  Otherwise, please see the help text.  
The potential risks of the study include the following:
LOSS OF CONFIDENTIALITY: Although patient identifiers and data will be stored on a secure server with limited access, basic contact information
such as the patient's name, address, and telephone number may be at risk if the server is compromised.
STANDARD OF CARE DRUG RISKS: Since both drugs are standardly used to prepare patients for pheochromocytoma surgery, participating in
this research study will not expose patients to additional risks beyond what is considered standard of care. Studies comparing phenoxybenazime
and doxazosin have mostly shown no difference in blood pressure fluctuations during surgery.
Risk/Benefit Analysis
4.0
*RISKS/BENEFIT ANALYSIS: Indicate how the risks to the participants are reasonable in relation to anticipated benefits, if any, to
participants and the importance of the knowledge that may reasonably be expected to result from the study:
Current retrospective data suggest that selective alpha blockade is as effective as non-selective blockade in addition to being less costly and
associated with less frequent adverse effects. A randomized controlled trial demonstrating this will result in societal cost savings and increased
health related quality of life in patients undergoing pheochromocytoma resection.

Data & Safety Monitoring Plan (continued)
Important Note:
All interventional studies involving more than minimal risk must include a Data and Safety Monitoring Plan (DSMP).  A DSMP is a plan established to
assure that each research study has a mechanism for appropriate oversight and monitoring of the conduct of the study to ensure the safety of participants
and the validity and integrity of the data.  The DSMP should indicate specifically whether or not there will be a formal Data Safety Monitoring Board (DSMB)
or Data Monitoring Committee (DMC).
Most, but not all studies (i.e., non-interventional studies) undergoing full board review will require a DSMP.  You will need a DSMP if any of the following
apply:

Certificate of Confidentiality for research not supported by NIH
The Certificate of Confidentiality button in this section is only if your study is NOT supported or conducted by NIH but you will obtain a
Certificate of Confidentiality (for example, for studies collecting information about illegal drug use).
If you previously checked this box for an NIH-supported study before the policy change, you do not need to change your
response here.
Certificates of Confidentiality are issued by the National Institutes of Health (NIH) to protect the privacy of research subjects by protecting
investigators and institutions from being compelled to release information that could be used to identify subjects with a research project.
Certificates of Confidentiality are issued to institutions or universities where the research is conducted. They allow the investigator and
others who have access to research records to refuse to disclose identifying information in any civil, criminal, administrative, legislative, or
other proceeding, whether at the federal, state, or local level.
Effective October 1, 2017, NIH has updated its policy for issuing Certificates of Confidentiality for NIH-funded and conducted research. For

Drugs/Biologics/Dietary Supplements
• Drug: The term "drug" means: articles recognized in the official United States Pharmacopoeia, official Homoeopathic Pharmacopoeia
of the United States, or official National Formulary, or any supplement to any of them; and articles intended for use in the diagnosis,
cure, mitigation, treatment, or prevention of disease in man or other animals; and articles (other than food) intended to affect the
structure or any function of the body of man or other animals.
• Biologics vs. Drugs: Most drugs consist of pure chemical substances and their structures are known. Most biologics, however, are
complex mixtures that are not easily identified or characterized. Biological products differ from conventional drugs in that they tend
to be heat-sensitive and susceptible to microbial contamination. This requires sterile processes to be applied from initial
manufacturing steps. For more information see: http://www.fda.gov/consumer/updates/biologics062608.html#drugs
• Dietary Supplements are products that are intended to supplement the diet and have one of the following ingredients:
 A vitamin
 A mineral
 An herb or other botanical
 An amino acid
 A dietary substance for use by man to supplement the diet by increasing the total daily intake
 A concentrate, metabolite, constituents, or an extract of combinations of these ingredients.

Human Gene Transfer/ Recombinant DNA
Studies involving gene transfer and/or recombinant DNA require approval of the UCLA Institutional Biosafety Committee (IBC).  Human gene
transfer is an investigational method for correcting defective genes responsible for disease development through one of the following
techniques: o A normal gene may be inserted into a nonspecific location within the genome to replace a nonfunctional gene. o An abnormal
gene could be swapped for a normal gene. o The abnormal gene could be repaired through selective reverse mutation, which returns the
gene to its normal function. o The regulation of a particular gene could be altered. Recombinant DNA molecules, according to the NIH
Guidelines, are defined as either: (i) molecules that are constructed outside living cells by joining natural or synthetic DNA segments to
DNA molecules that can replicate in a living cell, or (ii) molecules that result from the replication of those described in (i) above.
