BACKGROUND AND RATIONALE 
Therapies to decrease testosterone and other androgens are frequently utilized in men diagnosed with 
prostate cancer, and also in certain salivary gland tumors.[1, 2] Additionally, medications to block 
estrogen signaling are also commonly employed in men with estrogen and/or progesterone receptor 
positive breast cancer.[3] Although these therapies can have significant clinical efficacy, a rapid 
change in the circulating hormone levels can commonly cause patients to experience symptomatic 
hot flashes. Approximately 60-80% of prostate cancer patients being treated with either surgical (i.e. 
orchiectomy) or medical androgen deprivation therapy (ADT) will experience hot flashes.[4, 5] Hot 
flashes have been associated with negative impacts on patients’ reported quality of life, fatigue, and 
sleep disturbance.[6-11]  Additionally, patients with bothersome hot flashes may be less likely to 
complete the recommended course of ADT, which can negatively influence cancer prognosis. Given 
the prevalence of this symptom and the significance of associated toxicity, further study of potentially 
effective interventions is warranted. 
1.1 
Treatment of Hot Flashes in Men  
A variety of different therapies have been investigated for reducing hot flashes in men. Two 
progesterone analogs, megestrol and medoxyprogesterone, have randomized trial evidence 
demonstrating a significant reduction in hot flashes, with acceptable toxicity profiles.[12, 13] 
Both of these trials demonstrated that greater than 70% of patients receiving the study agents 
reported significant reductions in hot flashes. However, some oncologists are hesitant to 
prescribe these agents due to overexpression of progesterone receptors in a subset of patients 
with prostate cancer, and the uncertain clinical effects of these medication on oncologic 
outcomes.[14-16] Megestrol has also been associated with a decrease in prostate-specific 
antigen (PSA) after withdrawal suggesting some potential therapeutic effect by the drug.[17] 
Gabapentin, a gamma-aminobutyric acid analog, has also been shown to be effective at reducing 
hot flash frequency compared to placebo in men receiving ADT.[18] In that study, a dose-
dependent response to gabapentin was noted, with only patients receiving the highest dose (900 
mg/day) demonstrating a statistically significant moderate improvement in hot flash scores and 
frequencies, compared to placebo. However, there was only a 20% reduction and that only 
appeared after 3 weeks. A randomized trial assessing the efficacy of both venlafaxine, a 
serotonin-norepinephrine reuptake inhibitor (SNRI), and soy protein revealed that neither agent 
was effective at reducing hot flashes in men with prostate cancer.[19] This result is notable 
because venlafaxine has been shown, in multiple randomized studies, to improve hot flashes in 
women [20, 21], thus demonstrating the importance of investigating gender-specific responses 
to interventions for managing hot flashes. While there are evidence-based options for treating 
male hot flashes, further study is warranted to identify additional interventions that provide both 
providers and patients with more effective means of hot flash management, with tolerable side 
effects.  
1.2 
Oxybutynin for Hot Flashes  
Oxybutynin is an anti-cholinergic agent which is available in both oral and transdermal 
formulations. Currently, oxybutynin is approved by the Food and Drug Administration (FDA) 
for use in managing overactive bladder symptoms. Additionally there are randomized trial data 
supporting off label use for the management of hyperhidrosis, with studies showing that this 
effect is equal across both genders.[22-24] Oxybutynin has a very good safety profile, with the 
most common reported adverse effects being xerostomia, drowsiness, dizziness, mild cognitive 
effects, and urinary retention, which are typically mild in severity and resolve with 
discontinuation, if not tolerable.[25] 
In 2007, a manuscript reported retrospective data that supported the efficacy of oxybutynin for 
managing refractory hot flash symptoms in 52 cancer patients, including four men with ADT-

Update #02 
induced hot flashes.[26] The promising results of this study, which suggested a 70% response 
rate to oxybutynin with acceptable toxicity, led to the development of Phase III, double-blind, 
randomized trials comparing oxybutynin to placebo in women with hot flashes.[27, 28] One 
such trial demonstrated that moderate doses of oxybutynin substantially decreased hot flashes 
with mild to moderate toxicity. [27] More recently, our group completed another study which 
compared oxybutynin at doses of 2.5 and 5.0 mg BID to placebo in women with symptomatic 
hot flashes. These results were presented as an oral abstract at the 2018 San Antonio Breast 
Cancer Symposium, and showed that hot flash scores were significantly reduced from baseline 
in both the 2.5 mg (-10.6, SD 7.7) and 5.0 mg (-16.9, SD 15.6) treatment arms compared to 
placebo (-5.7, SD 10.2). Additionally, hot flash frequency was significantly improved for 
patients receiving both dose levels of oxybutynin (2.5 mg=60% reduction, 5.0 mg=77% 
reduction) over those treated with placebo (27% reduction). Reported treatment-related adverse 
effects for participants were typically mild and there was no difference in the discontinuation of 
the study drug between the oxybutynin and placebo arms. [28] 
Additionally, a recent letter to the editor in the New England Journal of Medicine highlighted a 
case study of a man with hot flashes related to ADT which were refractory to high doses of 
gabapentin and venlafaxine, who then experienced a dramatic improvement after starting 
oxybutynin 2.5 mg twice daily.[29]  Furthermore, members of our study team have anecdotally 
noted positive effects on hot flash symptoms when prescribing oxybutynin to manage urinary 
symptoms in men with prostate cancer. These observations, coupled with the positive effect of 
oxybutynin on hot flashes in women, support the conduct of a double-blind, placebo-controlled 
trial of oxybutynin for the management of hot flashes in men receiving ADT with a primary 
endpoint assessing the change in hot flash scores from baseline.  
1.3 
Study Design 
1.3.1 
Baseline period:  
We will utilize a one week period to obtain data regarding baseline hot flashes.  
1.3.2 
Hot flash measurement 
Patient reported outcome (PRO) measurements will be used as per the methodology that 
we described 18 years ago,[30] and that has also been used in trials conducted by other 
investigators. The primary endpoint of this study will assess the effects of the study 
interventions on patient reported hot flash scores. The calculation of this metric is defined 
in Section 2.1.1. Definitions of hot flash severity in men will be provided, based on data 
we collected from male patients who participated in a previous hot flash trial, and published 
25 years ago.[31] Previous studies for hot flashes in men have utilized the same outcome 
measures to assess the study drug’s efficacy and the hot flash score represents an ideal tool 
for quantitating multiple aspects of hot flash symptomatology.[12, 18, 30-32] We plan to 
use the Hot Flash Related Daily Interference Scale (HFRDIS), a tool developed by Dr. 
Janet Carpenter.[33]  We recently assessed face validity by asking 10 men with androgen 
deprivation hot flashes to review this tool.  All of the HFRDIS items were assessed as clear, 
appropriate, and easy to interpret. The items related to work and sexuality were identified 
as potentially difficult to answer if the individual was retired or not sexually active, 
however all of the men were able to provide a numeric score for these items. We also 
discussed the above with Dr. Janet Carpenter, who developed the HFRDIS tool and have 
identified other studies that have used the HFRDIS in men receiving androgen deprivation 
therapy.[34-36] These studies provide additional data supporting the reliability and validity 
of the 10-item instrument in this population. For example, Gonzalez, et al., (2015) provided 
evidence of construct validity in this population by demonstrating significant differences 
in scores between men receiving androgen deprivation therapy and men who only undergo

prostatectomy. [34] Beer, et al. (2010) demonstrated decreasing scores on both the HFD 
and HFRDIS following acupuncture in men undergoing androgen deprivation therapy, 
supporting concurrent validity of the HFRDIS [34]. 
1.3.4 
Cognitive effects  
One potential concern when using anti-cholinergic agents, such as oxybutynin, for 
extended periods is the potential negative impact on cognition via interaction with 
muscarinic receptors within the central nervous system. Prospective studies, conducted 
primarily in elderly patients with overactive bladder symptoms, have demonstrated 
conflicting findings with regard to the effects of oxybutynin on neuro-cognition relative to 
placebo.[37-40] Questions relating to patient-reported cognition will be asked via the 
Symptom Experience Questionnaire (Appendix V) at baseline and weekly during the 6-
week treatment period to help ascertain the effects of oxybutynin relative to placebo. These 
data will ultimately provide insight regarding the potential for cognitive toxicity with 
oxybutynin, which can be useful when considering the therapeutic index of this medication 
for treating hot flashes.  
2.0 
OBJECTIVES 
2.1 
Primary objective 
2.1.1 
To assess the effects of two doses of oxybutynin on hot flash scores (determined by 
multiplying the frequency of each defined hot flash grade by the severity [grade 0: none, 
1: mild, 2: moderate, 3: severe, and 4: very severe] and summing the values over a 24-
hour period) relative to placebo. 
2.2 
Secondary objectives 
2.2.1 
To assess study accrual rates and compliance with the therapy. 
2.2.2 
To characterize the safety and adverse event profile of two doses of oxybutynin in the 
study population. 
2.2.3 
To evaluate the consistency of the results across the various methods used to evaluate the 
efficacy of oxybutynin (i.e., hot flash scores versus hot flash frequencies, mean 
differences versus 50% or greater reduction since baseline, single day versus full week to 
define patients’ baseline hot flash scores). 
2.2.4 
To compare patient-reported quality of life and hot flash interference, as measured by the 
HFRDIS, across arms. 
2.2.5 
To compare other changes in patient symptoms, as measured by the Symptom Experience 
Questionnaire, across arms.

PATIENT SELECTION 
For questions regarding eligibility criteria, see the Study Resources page. Please note that the Study 
Chair cannot grant waivers to eligibility requirements.  
3.1 
On-Study Guidelines 
This clinical trial can fulfill its objectives only if patients appropriate for this trial are enrolled. 
All relevant medical and other considerations should be taken into account when deciding 
whether this protocol is appropriate for a particular patient. Physicians should consider the risks 
and benefits of any therapy, and therefore only enroll patients for whom this treatment is 
appropriate.  
Physicians should consider whether any of the following may render the patient inappropriate 
for this protocol: 
• 
Psychiatric illness which would prevent the patient from giving informed consent. 
• 
Medical condition such as uncontrolled infection (including HIV), uncontrolled 
diabetes mellitus or cardiac disease which, in the opinion of the treating physician, 
would make this protocol unreasonably hazardous for the patient. 
3.2 
Eligibility Criteria  
Use the spaces provided to confirm a patient’s eligibility by indicating Yes or No as appropriate. 
It is not required to complete or submit the following page(s).

Stratification Factors and Treatment Assignments 
The randomization routine is found in Section 13 (Statistical Considerations). 
4.5.1 
Stratification Factors 
Stratification factors include: 
4.5.1.1 Daily hot flash frequency at baseline: 4 to 9 hot flashes per day versus 10 
or more hot flashes per day 
4.5.1.2 Hot flash duration at baseline: less than 9 months versus 9 or more months, 
and 
4.5.1.3 Number of prior hot flash therapies (0 versus 1 or more). 
4.5.2 
Treatment Assignments  
The factors defined in Section 4.5.1 will be used as stratification factors. 
After the patient has been registered into the study, the values of the stratification factors 
will be recorded, and the patient will be assigned to one of the following treatment groups 
using the Pocock and Simon dynamic allocation procedure [41] which balances the 
marginal distributions of the stratification factors between the treatment groups.  
• 
Oxybutynin: 2.5 mL oral BID Days 8 through 49 (total of 42 days) 
• 
Oxybutynin: 5 mL oral BID Days 8 through 49 (total of 42 days)  
• 
Placebo: 2.5 mL oral BID Days 8 through 49 (total of 42 days)  
• 
Placebo: 5 mL oral BID Days 8 through 49 (total of 42 days)

Update #02 
Note: Oxybutynin concentration = 1mg/mL.  
4.6 
Procedures for Double-Blinding the Treatment Assignment 
After the treatment assignment has been ascertained by randomization, the Registration 
Specialist will notify the designated unblinded data manager/nurse/pharmacist at the patient’s 
institution. The name of this designated unblinded contact person is to be indicated in the OPEN 
registration system at the time of registration. This contact person may not be involved in 
assessing adverse events or any other outcome measure and should not be the same person 
listed on page one of the OPEN registration form as the person completing the form. The OPEN 
registration form should provide the source of communication, either fax or e-mail, and the 
appropriate contact information. The Registration Specialist will then communicate the 
treatment assignment “Oxybutynin 2.5 mL, Placebo 2.5 mL, Oxybutynin 5 mL or Placebo 5 
mL” to designated contact at the patient’s institution. 
Once the treatment assignment has been communicated, the designated contact should prepare 
the dose of drug or placebo for delivery to the patient.  
The dose will be prepared and labeled as “oxybutynin/placebo” so that the contents are not 
discernible to the person administering the treatment. 
The pharmacist or designated contact person will maintain records that indicate the identity of 
the patient and their corresponding treatment assignment. The pharmacist or designated contact 
person at the treating site will maintain records that indicate the identity of the patient and their 
corresponding study medication code number. 
4.7 
Cross-Over Re-registration (step 2) Procedures  
Patients who complete 6 weeks of study treatment and submit their questionnaires will be 
unblinded per the unblinding procedures in Section 8.3.2. In order to unblind the patient, site 
staff must call the Alliance Registration Office (507-284-4130) during regular business hours to 
find out if the patient was receiving oxybutynin or placebo. Site staff must ensure that the 
questionnaires associated with the initial cycle of treatment have been completed and sent to the 
study staff by the patient before proceeding with unblinding, as these are related to the 
assessment of the primary endpoint of the study.  
If the patient was receiving placebo, he will be allowed to cross over and receive oxybutynin at 
the discretion of the treating physician. 
Patients who choose to enter the cross-over phase will be re-registered as follows:   
1. Site staff will log into the OPEN registration system and select the appropriate patient. 
2. Then select the next registration step. (Step 2) 
3. Complete the OPEN Enrollment Form for the patient to be re-registered for the 
continuation phase. The patient will be re-registered to oxybutynin 2.5 or 5.0 mL, 
equivalent to whichever dose of placebo the patient was receiving prior to unblinding. 
4. Verify the patient turned in their questionnaires for the initial cycle of treatment, yes/no. 
5. Once the re-registration to the crossover phase is successfully completed, a confirmation 
email will be sent to the CRP. 
If assistance is needed with this process, contact the Alliance Registration Office at 
 
Following re-registration, the designated contact will be notified by the CRP so that s/he can 
prepare drug for delivery to the patient. Patient should be told that he may need to come back to 
the clinic to pick up open label supplies.

Submission of Patient Completed Measures 
Patient-completed questionnaire booklets for this study are to be ordered prior to the registration 
of any patients (see Section 4.3). Samples of questionnaire booklets are available in Appendices 
I-VII for reference and IRB submission only. They are not to be used for patient completion. 
Booklets must be given to patients to complete and patients should be instructed to return the 
booklets to site staff either in person or by mail and site staff will enter patient responses into 
Medidata Rave. At visits in which booklets are to be completed, the booklet should be given to 
the patient before any discussion of the patient’s health status or test results. The PRO 
submission schedule is provided in the Study Calendar.  
Weekly Booklets: Six booklets to be completed weekly must be given to patients to complete 
at home and patients should be instructed to return the booklets by mail weekly or to return the 
booklets at their regularly scheduled clinic visit. Institutions must provide patients with 
sufficient self-addressed stamped envelopes for this purpose. Site staff will enter patient 
responses into Rave upon receipt of the completed booklets. 
Verbal administration of the measures for visually impaired patients is permitted if the verbal 
administration of the measure is conducted in a language understandable to the patients.  
6.2.1 
Patient Language Considerations 
The patient reported measures are available in English. Participation in Alliance A222001 
is restricted to patients who are able to speak, understand and read English. Ad-hoc 
translation of patient-completed measures is not permitted.

TREATMENT PLAN/INTERVENTION 
Protocol treatment is to begin ≤ 8 days of registration.  
For questions regarding treatment, please see the study contacts page. 
This is a randomized, double-blind trial. The pharmacist or designated contact (see Section 4.6) at 
the institution will be informed of the patient’s randomization, so that they may prepare oxybutynin 
or placebo for delivery to the patient (see Section 10.0). 
The placebo arms will be half the size as the oxybutynin arms, as they will be combined to have a 
placebo group with the same number of patients as the two different dose groups. This allows all 
patients to be blinded as to whether they are receiving active drug or a placebo. 
Patients will be assigned to one of the following treatment groups, and continue to receive treatment 
for 6 weeks (i.e., 42 days): 
 
Days 1-7 
Days 8-49 
Oxybutynin 2.5 mL  
Patients on all arms will be 
asked to complete 
questionnaires as baseline 
symptom documentation on 
Days 1-7, before starting 
study treatment on Day 8. 
Oxybutynin 2.5 mL* PO twice a day 
Placebo 2.5 mL 
Placebo 2.5 mL* PO twice a day 
Oxybutynin 5 mL 
Oxybutynin 5.0 mL* PO twice a day 
Placebo 5.0 mL 
Placebo 5.0 mL* PO twice a day 
* 
Note that the concentration of oxybutynin is 1 mg per 1 ml, so that placebos and active 
treatments will maintain blinding. 
Upon completion of the 6-week study period, patients will be contacted to ensure they have 
completed all required questionnaires. 
7.1 
Baseline Symptom Documentation 
The patient will be instructed not to take any study medication for the first seven days of the 
study, but to complete their daily questionnaires (Baseline Symptom Documentation – 
Appendix II) during this baseline period. At the end of the week, patients will complete 
Symptom Experience Questionnaire (Appendix V) and Hot Flash Related Daily Interference 
Scale (Appendix VI). 
7.2 
Oxybutynin/Placebo 
Beginning on Day 8 of the study, and for the subsequent six weeks, patients will be instructed 
to take their study medication as illustrated below.  
• 
Oxybutynin: 2.5 mL oral BID Days 8 through 49 (total of 42 days) 
• 
Placebo: 2.5 mL oral BID Days 8 through 49 (total of 42 days)  
• 
Oxybutynin: 5.0 mL oral BID Days 8 through 49 (total of 42 days)  
• 
Placebo: 5.0 mL oral BID Days 8 through 49 (total of 42 days) 
7.3 
Patient Unblinding and optional crossover  
Patients will be contacted on their last scheduled day of the study treatment.  It should be assured 
that the patient has completed his questionnaires. Then the patient may be unblinded per the 
procedures described in Section 8.3.  

Alliance A222001

Version Date 09/14/22 
 
Update #02 
If the patient was receiving placebo, he may choose to crossover to oxybutynin 2.5 or 5.0 mL, 
equivalent to whichever dose of placebo the patient was receiving prior to unblinding. This 
crossover will require a second registration (see Section 4.7 for re-registration instructions). The 
duration of treatment for patients who crossover will be 6 weeks.

DOSE AND TREATMENT MODIFICATIONS, UNBLINDING  
8.1 
Ancillary Therapy, Concomitant Medications, and Supportive Care 
8.1.1 
Patients should not receive any other treatment or participate in trials which would 
be considered treatment for hot flashes or impact the primary endpoint. 
Simultaneous enrollment on other treatment studies is not allowed during the 7 week 
study period.  
8.1.2 
Patients should receive full supportive care while on this study.  This includes blood 
product support, antibiotic treatment, and treatment of other newly diagnosed or 
concurrent medical conditions.  All blood products and concomitant medications such as 
antidiarrheals, analgesics, and/or antiemetics received from the first day of study 
treatment administration until 30 days after the final dose will be recorded in the medical 
records. 
8.1.3 
Treatment of the patient’s cancer should not be influenced by this study. If the 
patient stops ADT while participating in the study, it should be recorded on the study 
forms. 
8.2 
Dose Modifications 
Dose modifications to the patient’s cancer treatment are up to the discretion of the treating 
physician.  During participation in the study, if the patient develops any symptoms attributed to 
the drug that are considered to be of unacceptable severity by the patient and/or physician, 
oxybutynin/placebo doses will be adjusted as follows: 
Dose modifications for adverse events 
Low Dose 
(2.5 mL BID) 
Maintain prescribed dose, but decrease frequency from BID to once 
daily. 
If symptoms are still unacceptable by the patient and/or physician, 
drug will be discontinued and patient will be taken off study. 
High Dose 
(5.0 mL BID) 
If toxicity occurs, decrease dose from 5 mL BID to 2.5 mL BID. If 
symptoms persist, decrease dose from 2.5 mL BID to 2.5 mL once 
daily. If symptoms are still unacceptable by the patient and/or 
physician, the drug will be discontinued and patient will be asked to 
complete questionnaires to date and then be taken off study. 
Urinary retention:  For patients on both doses, if at any time during treatment, the patient 
develops severe urinary symptoms, he should immediately discontinue study treatment and get 
a post void residual ultrasound assessment as clinically indicated.

Unblinding Procedures  
Unblinding can be done only in cases of an emergency or at the end of study treatment. Follow 
the directions below to unblind patient treatment. Please note that if a treatment assignment is 
unblinded, the patient must discontinue protocol therapy. 
8.3.1 
Emergency Unblinding Procedures 
Examples of emergencies include 1) a life-threatening unexpected adverse event that is at 
least possibly related to the investigational agent and for which unblinding would influence 
treatment decisions; or 2) medication error, such as accidental overdose. Expected adverse 
events are listed in the “Toxicities” section below.  
Contact the Alliance Executive Officer on call by calling 
 
  
The institution must provide the following information to the Alliance Executive Officer:  
• 
Alliance study ID (i.e., “A222001”)  
• 
Alliance patient ID number (e.g., “999999”)  
• 
Patient initials (e.g., “L,F,M”)  
• 
Institution name  
• 
Name and telephone number of treating physician  
• 
Name and contact information of person requesting the unblinding procedure  
• 
Name and contact information of person to inform of treatment assignment  
• 
Reason for emergency unblinding  
Please remember that emergency unblinding request may be authorized only by an Alliance 
Executive Officer, and emergency unblinding applies only if unblinding would influence 
management of the medical situation. After the Executive Officer deems unblinding is 
warranted, the treatment assignment will be provided to the contact person at the treating 
site. 
8.3.2 
Protocol-specified unblinding—Crossover Unblinding at end of treatment 
The steps for unblinding a patient upon completion of study treatment are as follows:  
1. Patient has completed 6 weeks of study treatment.  
2. Site completes the form documenting end of treatment in Rave. 
3. Site calls the registration office to unblind the patient; registration office confirms 
receipt of the end of treatment form with statistics and data center in order to 
communicate patient treatment assignment to site. 
Contact the Alliance Registration Office at 
during regular business hours. 
Upon confirmation by the Primary Statistician (or designee) that the criteria for unblinding 
have been met, the treatment assignment may be unblinded. No Alliance Executive Officer 
(or designee) approval is required.

Any medical event equivalent to CTCAE grade 3, 4, or 5 that precipitates hospitalization 
(or prolongation of existing hospitalization) must be reported regardless of attribution and 
designation as expected or unexpected with the exception of any events identified as 
protocol-specific expedited adverse event reporting exclusions (see below). 
Any event that results in persistent or significant disabilities/incapacities, congenital 
anomalies, or birth defects must be reported via CTEP-AERS if the event occurs following 
treatment with an agent under an IND. 
Use the NCI protocol number and the protocol-specific patient ID provided during trial 
registration on all reports. 
9.3.3 
Additional Instructions or Exclusions to CTEP-AERS Expedited Reporting 
Requirements  
All adverse events reported via CTEP-AERS (i.e., serious adverse events) should also be 
forwarded to your local IRB. 
Alliance A222001 uses a drug under an Alliance IND. The reporting requirements for 
investigational agents under a CTEP IND should be followed for all agents (any arm) in 
this trial. 
Treatment expected adverse events include those listed in Section 10.0 and in the package 
insert. 
CTEP-AERS reports should be submitted electronically. 
Death 
Death due to progressive disease should be reported as Grade 5 “Disease progression” in 
the system organ class (SOC) “General disorders and administration site conditions.” 
Evidence that the death was a manifestation of underlying disease (e.g., radiological 
changes suggesting tumor growth or progression: clinical deterioration associated with a 
disease process) should be submitted.  
Any death occurring within 30 days of the last dose, regardless of attribution to the 
investigational agent/intervention requires expedited reporting within 24 hours.  

Alliance A222001 
29 
Version Date 09/14/22 
 
Update #02 
Any death occurring greater than 30 days after the last dose of the investigational 
agent/intervention requires expedited reporting within 24 hours only if it is possibly, 
probably, or definitely related to the investigational agent/intervention. 
New Malignancies 
All new malignancies must be reported via CTEP-AERS whether or not they are thought 
to be related to either previous or current treatment. All new malignancies should be 
reported, i.e. solid tumors (including non-melanoma skin malignancies), hematologic 
malignancies, myelodysplastic syndrome/acute myelogenous leukemia, and in situ tumors.  
Whenever possible, the CTEP-AERS reports for new malignancies should include tumor 
pathology, history or prior tumors, prior treatment/current treatment including duration, 
any associated risk factors or evidence regarding how long the new malignancy may have 
been present, when and how the new malignancy was detected, molecular characterization 
or cytogenetics of the original tumor (if available) and of any new tumor, and new 
malignancy treatment and outcome, if available. 
Secondary Malignancy 
A secondary malignancy is a cancer caused by treatment for a previous malignancy (e.g., 
treatment with investigational agent/intervention, radiation or chemotherapy). A secondary 
malignancy is not considered a metastasis of the initial neoplasm.  
CTEP requires all secondary malignancies that occur following treatment with an agent 
under an NCI IND/IDE be reported via CTEP-AERS. Three options are available to 
describe the event:  
• 
Leukemia secondary to oncology chemotherapy (e.g., acute myelocytic leukemia 
[AML])  
• 
Myelodysplastic syndrome (MDS)  
• 
Treatment-related secondary malignancy  
Any malignancy possibly related to cancer treatment (including AML/MDS) should also 
be reported via Rave.  
Second Malignancy 
A second malignancy is one unrelated to the treatment of a prior malignancy (and is NOT 
a metastasis from the initial malignancy).  Second malignancies require ONLY routine 
reporting unless otherwise specified.

The current version of the package insert for the agents will be accessible to site investigators 
and research staff through the Alliance office. 
Availability 
Oxybutynin oral syrup is available as 5 mg/5mL concentration with raspberry flavor.  The 
solution contains citric acid, D&C Yellow No 10, FD&C Blue No 1, glycerin, liquid sugar, 
methylparaben, propylene glycol, sodium citrate, and sorbitol solution.   
Storage and Stability 
Store at Controlled Room Temperature, 15–30°C (59–86°F). 
Administration 
Oxybutynin/placebo will be administered at a dosage of either 2.5mg/2.5ml or 5mg/5ml two 
times daily. Study medication can be taken with or without food.  
Drug Interactions 
The concomitant use of oxybutynin with other anticholinergic drugs or with other agents 
which produce dry mouth, constipation, somnolence (drowsiness), and/or other 
anticholinergic-like effects may increase the frequency and/or severity of such effects. 
Anticholinergic agents may potentially alter the absorption of some concomitantly 
administered drugs due to anticholinergic effects on gastrointestinal motility. Anticholinergic 
agents may also antagonize the effects of prokinetic agents, such as metoclopramide.  
Mean oxybutynin plasma concentrations were approximately 3 to 4 fold higher when 
oxybutynin chloride tablets were administered with ketoconazole, a potent CYP3A4 inhibitor.  

Alliance A222001 
32 
Version Date 09/14/22 
 
Update #02 
Other CYP3A4 inhibitors, such as antimycotic agents (e.g., itraconazole and miconazole) or 
macrolide antibiotics (e.g., erythromycin and clarithromycin), may alter oxybutynin mean 
pharmacokinetic parameters. The clinical relevance of such potential interactions is not 
known. Caution should be used when such drugs are co-administered. 
Pharmacokinetics  
Time to peak concentration: Oral: 0.89 + 0.34 hours. Oxybutynin contains both the R- and S-
isomers, the R-isomer contributes most to the antimuscarinic activity of oxybutynin. 
Bioavailability: The absolute bioavailability of oxybutynin is 6%, although there is wide 
interindividual variation following oral administration. Food slightly delays absorption and 
increases bioavailability by 25%. 
Metabolism: Hepatic, extensive particularly the CYP3A4 isoenzyme 
Half-life elimination: Normal renal function: 2-3 hours 
Excretion: Renal, less than 0.1% unchanged as parent compound or as the metabolite N-
desethyloxybutynin.  
Adverse Events 
Consult the package insert for the most current and complete information.  
Following administration of oxybutynin chloride, the following symptoms may occur:  
Cardiovascular: Palpitations, tachycardia, vasodilatation  
Dermatologic: Decreased sweating, rash  
Gastrointestinal/Genitourinary: Constipation, decreased gastrointestinal motility, dry mouth,

Nursing Guidelines 
1. Use extreme caution when oxybutynin is administered with any other anticholinergic 
agents as increased side effects can occur (i.e. dry mouth, constipation, somnolence).  
2. Instruct patients to report any palpitations or tachycardia to the study team. 
3. Patients may experience rash. Inform patients to report skin changes to the study team. 
4. Warn patients that they may have decreased sweating abilities. They should use caution 
if out in the heat and to avoid becoming overheated.  
5. Gastrointestinal effects can be seen including constipation, decreased GI motility, 
nausea, vomiting, and dry mouth. Treat symptomatically and monitor for effectiveness. 
6. Warn patients of possible urinary hesitation and retention. If patient has difficulty 
voiding they should report this to the study team immediately. 
7. Patients may experience neurologic side effects including dizziness, hallucinations, 
drowsiness and/or insomnia. Instruct patients to use caution when operating a vehicle 
or other activities that require close attention until they know how they respond to agent.

11.0 MEASURES 
Before they start treatment and during the course of study treatment, patients will be asked to assess 
the severity of their hot flashes (descriptions provided in Appendix I) and complete a baseline 
symptoms determination (Appendix II) (Week 1 only),  daily Hot Flash Diaries (Appendix IV), along 
with weekly Symptom Experience Questionnaires (Appendix V). The Hot Flash Related Daily 
Interference Scale (HFRDIS) (Appendix VI) will be completed prior to initiation of and at the 
conclusion of study treatment. All patients will receive weekly phone calls from study staff 
(Appendix VII) to document compliance with study drug, encourage completion of requisite study 
questionnaires, collect adverse events and address any patient concerns or problems. 
11.1 
Baseline Symptom Determination (Appendix II) 
The baseline symptoms determination is completed after registration and randomization but 
prior to initiation of study treatment. This form has patients record the number of total hot flashes 
they experience on a daily basis, along with the number of hot flashes according to severity 
(mild, moderate, severe, or very severe) over the first 7 days of the study period. It is estimated 
that completing the baseline symptom determination will take 3-5 minutes daily. Questionnaires 
should be returned to the investigator at the end of the baseline week (week 1) and at the end of 
treatment (i.e., after the 7th week following study entry).  The patient should be supplied with 
two addressed/stamped envelopes for returning the forms. 
11.2 
International Prostate Symptom Score (IPSS) (Appendix III) 
This tool has been added to this study at screening and to be completed at the end of every week 
of treatment in response to FDA recommendations to ensure that patients do not have urinary 
retention issues. This is an 8-item scale, widely used in clinical practice, which measures lower 
urinary tract symptoms. It includes questions encompassing incomplete bladder emptying, 
frequent urination, urgency, nocturia, intermittency, weak stream, straining, and quality of life 
related to urinary symptoms[42]. 
There are robust data to suggest that prostate cancer patients on active surveillance experience 
significantly decreased urinary health relative to men without prostate cancer. In a cohort 
analysis of 6,000 community dwelling older men, we observed that compared to men without 
prostate cancer, men with prostate cancer on active surveillance (i.e. those who had not 
undergone treatment) reported a significantly diminished quality of life due to urinary 
symptoms[43]. 
11.3 
Hot Flash Diary (Appendix IV) 
The Hot Flash Diary is completed daily during each of the 6 weeks that patients are taking the 
study treatment. Like the Baseline Symptom Determination, the form has patients report the 
number and severity of their daily hot flashes. Additionally, it has them report how many doses 
of the study drug they took on each day. Completion of the Hot Flash Diary is anticipated to 
take less than a minute per day. 
11.4 
Symptom Experience Questionnaire (Appendix V) 
The Symptom Experience Questionnaire is collected at the end each of the 7 weeks of the study 
period. This form collects patient reported toxicity and quality of life data using a 0-10 scale, 
with one question that allows an unstructured response to report symptoms not captured in the 
questions provided. Estimated completion time for the Symptom Experience Questionnaire is 
10-15 minutes each week.

Hot Flash Related Daily Interference Scale (HRFDIS) (Appendix VI) 
Hot Flash Related Daily Interference Scale (HFRDIS), a tool developed by Dr. Janet 
Carpenter.[33]  We recently asked 10 men with androgen deprivation hot flashes, to review this 
tool.  All of the HFRDIS items were assessed as clear, appropriate, and easy to interpret. The 
items related to work and sexuality were identified as potentially difficult to answer if the 
individual was retired or not sexually active, however all of the men were able to provide a 
numeric score for these items. We also discussed the above with Dr. Janet Carpenter, who 
developed the HFRDIS tool and have identified other studies that have used the HFRDIS in men 
receiving androgen deprivation therapy [34-36]. These studies provide additional data 
supporting the reliability and validity of the 10-item instrument in this population.  
The Hot Flash Related Daily Interference Scale is to be completed by all participants at baseline 
(Week 1) and at the conclusion of the study (Week 7). It will also be completed at the end of 
Weeks 2 and 4 of study treatment, as it asks questions related to hot flashes over the past two 
weeks.  This 10-item questionnaire uses a 1-10 scale to assess the interference caused by hot 
flash symptoms with specific aspects of patients’ personal lives. Each completion of the 
HFRDIS is expected to take 5 minutes. 
11.6 
Nurse Telephone Contact (Appendix VII)  
All patients will receive weekly phone calls from study staff, to document compliance with 
study drug, encourage completion of requisite study questionnaires, and address any patient 
concerns or problems and assess adverse events. The nurse weekly phone calls will continue 
during the optional cross over phase, to assess and collect adverse events during this time.  
12.0 END OF TREATMENT/INTERVENTION

Follow-up  
12.3.1 Duration of Follow-up  
Protocol treatment is to continue for 6 weeks. Please follow the data submission 
requirements outlined in the study calendar (Section 5.0). There is no further clinical or 
survival follow up beyond the 6-week study period. For patients who participate in the 
optional crossover phase, there will be a 6-week follow up.  
12.3.2 Follow-up for Patients who Stop Study Treatment Early  
Protocol treatment is to continue for 6 weeks. Patients who do not complete 6 weeks of 
protocol treatment for any reason will still be expected to follow the data submission 
requirements outlined in the study calendar (Section 5.0) and will thus be followed up until 
6 weeks post-randomization. 
Follow up for patients who stop due to toxicity 
If the patient decides to discontinue the study medication because of unacceptable side 
effects, he is to call the study nurse.  The patient should be encouraged to complete 
diaries/questionnaires to date and send them in. The patient can then be taken off study. 
The off-study date to be used is either (1) the day after the patient took some study 
medication OR (2) the day after the patient last recorded some research data on the patient 
questionnaire--whichever occurred last. 
12.4 
Extraordinary Medical Circumstances 
If, at any time the constraints of this protocol are detrimental to the patient's health and/or the 
patient no longer wishes to continue protocol therapy, protocol therapy shall be discontinued. In 
this event: 
• 
Document the reason(s) for discontinuation of therapy on data forms. 
• 
Follow the patient for protocol endpoints as required by the Study Calendar.

Managing ineligible patients and registered patients who never receive protocol 
intervention  
Definition of ineligible patient 
A study participant who is registered to the trial but does not meet all of the eligibility criteria 
is deemed to be ineligible.  
Follow-up for ineligible patients who continue with protocol treatment 
Patients who are deemed ineligible after registering may continue protocol treatment, provided 
the treating physician, study chair, and executive officer agree there are no safety concerns if 
the patient continues protocol treatment. All scans, tests, and data submission are to continue as 
if the patient were eligible. Notification of the local IRB may be necessary per local IRB 
policies. 
Follow-up for ineligible patients who discontinue protocol treatment 
For patients who are deemed ineligible after registering to the trial, who start treatment, but then 
discontinue study treatment, the same data submission requirements are to be followed as for 
those patients who are eligible and who discontinue study treatment. 
Follow-up for patients who are registered, but who never start study treatment 
For all study participants who are registered to the trial but who never receive study intervention 
(regardless of eligibility), the follow-up requirements are specified below:

13.0 STATISTICAL CONSIDERATIONS 
13.1 
Overview 
This randomized four-arm, double-blind, placebo-controlled phase II trial will assess the 
efficacy and safety of oxybutynin for reducing hot flash scores in men receiving androgen 
deprivation therapy. The primary endpoint of this phase II trial is hot flash scores at 6 weeks 
post-randomization. All analyses will follow an intent-to-treat approach that includes all 
randomized patients who meet eligibility criteria. 
13.2 
Study Design 
Patients will be randomly assigned to oxybutynin at 2.5 mL twice daily, oxybutynin at 5.0 mL 
twice daily, placebo at 2.5 mL twice daily, or placebo at 5.0 ml twice daily in a 2:2:1:1 ratio 
according to the dynamic allocation scheme. Stratification factors will include daily hot flash 
frequency at baseline (4 to 9 hot flashes per day versus 10 or more hot flashes per day), hot flash 
duration at baseline (less than 9 months versus 9 or more months), and number of prior hot flash 
therapies (0 versus 1 or more). The study design includes two placebo arms to match the dose 
of the two oxybutynin arms; however, patients randomized to the two placebo arms will be 
combined to form a single placebo arm for analysis. All analyses will follow an intent-to-treat 
approach that includes all randomized patients who meet eligibility criteria. 
13.3 
Study Endpoints 
Important endpoints for this phase II trial relate to (1) efficacy of oxybutynin as measured by 
hot flash scores (primary) and hot flash frequency, (2) safety as measured by the presence of 
CTCAE v5.0-determined grade 3 or higher adverse events, (3) tolerability as measured by 
relevant patient-reported symptoms on the Symptom Experience Questionnaire (Appendix V), 
(4) feasibility regarding the conduct of this trial as measured by patient accrual and treatment 
adherence, and (5) patient-reported quality of life and hot flash interference as measured by the 
Hot Flash Related Daily Interference Scale (HFRDIS; Appendix VI). Treatment adherence rates 
will be calculated by dividing the number of patients who completed treatment per protocol by 
the number of patients who started treatment. Hot flash scores and frequencies will be measured 
by patients’ hot flash diaries (Appendix IV). Daily hot flash scores will be computed by 
multiplying the frequency of each hot flash grade within a 24-hour period by the severity of the 
hot flash (grade 0: none, 1: mild, 2: moderate, 3: severe, and 4: very severe) and then summing 
all the values. Weekly hot flash scores will be computed by averaging these hot flash scores 
across the 7 days of each week. Weekly hot flash scores will be computed as long as hot flash 
scores from at least 1 of the 7 days of each week are available. However, the number of missing 
(daily) hot flash scores each week will be tabulated. 
13.4 
Analysis Plan 
To assess efficacy, a mixed model will be estimated that includes baseline and weekly hot flash 
scores across the 6-week treatment period. The mixed model will include a fixed intercept; fixed 
effect for time, arm, and arm by time interaction; and residual covariance matrix based on the 
observed covariances. Alternative structures will be investigated for the residual covariance 
matrix, with final selection based on convergence of the mixed model and minimization of the 
Akaike information criterion. Stratification factors used in the randomization as well as baseline 
patient characteristics and prognostic factors may be included in the mixed model as covariates 
if imbalances across arms occur. For this mixed model, time will be treated as nominal (not 
continuous), such that the mixed model will not be making assumptions about the trajectory of 

Alliance A222001 
38 
Version Date 09/14/22 
 
Update #02 
patients’ hot flash scores over time. Estimates from the mixed model will be used to construct 
90% confidence intervals for mean differences in hot flash score reduction from baseline to 6 
weeks post-randomization between the oxybutynin and placebo arms (i.e., Arm A versus Arms 
C and D combined; Arm B versus Arms C and D combined). To control the Type I error rate, a 
fixed sequence procedure will be employed such that the following two tests will be sequenced 
rather than conducted simultaneously. Hot flash score reduction from baseline to 6 weeks will 
be compared across patients assigned to oxybutynin at 5.0 mL twice daily (Arm B) and patients 
assigned to placebo (Arms C and D combined) using a contrast estimated via the mixed model. 
The contrast will involve a two-sided t-test with a nominal significance level of α = .10. If and 
only if this test is significant, hot flash score reduction from baseline to 6 weeks will be formally 
compared across patients assigned to oxybutynin at 2.5 mL twice daily (Arm A) and patients 
assigned to placebo (Arms C and D combined) using a second contrast estimated via the mixed 
model. This contrast will also involve a two-sided t-test with a nominal significance level of 
α = .10. The proposed sequencing is based on the assumption that the effect of oxybutynin will 
increase monotonically with respect to dose. If p ≤ .10 for both tests, we will conclude that both 
dosing schedules significantly improved hot flash scores at 6 weeks relative to placebo. If 
p ≤ .10 for the first test but p > .10 for the second test, we will conclude that the higher dosing 
schedule significantly improved hot flash scores at 6 weeks relative to placebo but that the lower 
dosing schedule did not significantly improve hot flash scores at 6 weeks relative to placebo. 
Finally, if p > .10 for the first test, we will conclude that neither dosing schedule significantly 
improved hot flash scores at 6 weeks relative to placebo. In practice, if p > .10 for the first test, 
we will still conduct the second test, but as an exploratory analysis rather than as a primary 
analysis. We will also conduct a responder analysis at 6 weeks comparing the proportion of 
patients who experience a clinically significant improvement in hot flash scores since baseline 
across the oxybutynin and placebo arms using Fisher’s exact test, χ2 test, or logistic regression. 
Stratification factors used in the randomization as well as baseline patient characteristics and 
prognostic factors may be included in the logistic regression model as covariates if imbalances 
across arms occur. A clinically significant improvement will be defined as a 50% or greater 
reduction in hot flash scores since baseline based on preliminary evidence suggesting that 
patients consider a 50% or greater reduction in frequency of moderate to severe hot flashes to 
be a meaningful improvement.[41, 42] Patients who experience a 50% or greater reduction in 
hot flash scores since baseline will be deemed responders, while the remaining patients 
(including those with missing hot flash scores) will be deemed non-responders. As an 
exploratory analysis, we will investigate whether these efficacy results differ when using a 
single day rather than a full week to define patients’ baseline hot flash scores. 
Weekly hot flash frequencies (as opposed to weekly hot flash scores) will be compared across 
the oxybutynin and placebo arms in a manner similar to above using a mixed model that 
accounts for the observed distribution of weekly hot flash frequencies. A fixed sequence 
procedure will be employed. For the responder analysis, patients who experience a 50% or 
greater reduction in hot flash frequency since baseline will be deemed responders, while the 
remaining patients (including those with missing hot flash frequencies) will be deemed non-
responders. Finally, consistency of the results will be assessed across the various methods used 
to evaluate the efficacy of oxybutynin in this trial (i.e., hot flash scores versus hot flash 
frequencies, mean differences versus 50% or greater reduction since baseline, single day versus 
full week to define patients’ baseline hot flash scores). 
To assess safety, the proportion of patients experiencing a grade 3 or higher adverse event will 
be summarized by arm. We expect this proportion to be extremely low for all arms. 
To assess tolerability, mixed models similar to the one described above will be estimated that 
include baseline and weekly patient-reported symptoms as measured by the Symptom 

Alliance A222001 
39 
Version Date 09/14/22 
 
Update #02 
Experience Questionnaire (Appendix V) across the 6-week treatment period. A single mixed 
model will be developed for each patient-reported symptom. Estimates from the mixed models 
will be used to construct 90% confidence intervals for mean differences in patient-reported 
symptoms between the oxybutynin and placebo arms (i.e., Arm A versus Arms C and D 
combined; Arm B versus Arms C and D combined) at 6 weeks post-randomization. Contrasts 
estimated via the mixed models will involve a two-sided t-test with a nominal significance level 
of α = .10. 
To assess feasibility, the time required to accrue 87 patients will be reported. To move forward 
with a phase III trial, an average accrual rate of 4 patients per month (starting 4 months after 
enrollment begins, to account for the time required for multiple institutions to activate the trial) 
would be desired. The treatment adherence rate (i.e., the number of patients who completed 
treatment per protocol divided by the number of patients who started treatment) will be 
summarized by arm. 
To assess patient-reported quality of life and hot flash interference, mixed models similar 
to the one described above will be estimated that include patients’ scores on the HFRDIS 
(Appendix VI) across the 6-week treatment period. A single mixed model will be developed for 
each HFRDIS item. Estimates from the mixed models will be used to construct 90% confidence 
intervals for mean differences in patient-reported quality of life and hot flash interference 
between the oxybutynin and placebo arms (i.e., Arm A versus Arms C and D combined; Arm B 
versus Arms C and D combined) at 6 weeks post-randomization. Contrasts estimated via the 
mixed models will involve a two-sided t-test with a nominal significance level of α = .10. 
Attempts to minimize missing data will be made through site training and data monitoring (e.g., 
form delinquency notifications, queries; see Section 6.1.3). The proportion of, and reported 
reasons for, missing data will be presented by time point and arm. Correlation analysis and 
logistic regression analysis will be used to examine whether baseline patient characteristics and 
prognostic factors predict missingness. The primary analysis will provide unbiased parameter 
estimates under a missing completely at random or missing at random mechanism. However, a 
sensitivity analysis will be conducted to assess the robustness of the results across various 
assumptions about the missing data. 
13.5 
Sample Size and Power 
As this is a pilot trial, the sample size was determined based on feasibility and logistical 
considerations rather than on power for hypothesis testing. We aim to enroll 26 evaluable 
patients per oxybutynin arm and 13 evaluable patients per placebo arm (i.e., 78 evaluable 
patients total). For the primary aim, 26 evaluable patients per oxybutynin arm and 13 evaluable 
patients per placebo arm with 6 weekly hot flash scores provide 76% power to detect a mean 
difference in hot flash score reduction from baseline when comparing each oxybutynin arm (5.0 
mL twice daily or 2.5 mL twice daily  to the placebo arm (both placebo arms combined) based 
on a two-sided t-test estimated via a mixed model, nominal significance level of α = .10, 
intraclass correlation of .50, and population standardized mean difference of 0.50 (i.e., Cohen’s 
convention for a moderate effect size)[44]. In a similar study in women, Cohen’s d equaled 0.85 
when comparing the higher dose oxybutynin arm (2.5 mL twice daily escalated to 5.0 mL twice 
daily) to the placebo arm, and Cohen’s d equaled 0.54 when comparing the lower dose 
oxybutynin arm (2.5 mL twice daily) to the placebo arm [45]. An additional 9 patients will be 
accrued to account for a 10% loss in sample size due to ineligibility, major treatment violation, 
or cancellation. Maximum projected accrual is, therefore, 87 patients.

13.6 
Accrual Time and Study Duration 
The anticipated accrual rate is approximately 7 patients per month, based on our most-recent 
previous male hot flash trial (conducted 15 years ago to evaluate gabapentin) and recent survey 
information. Therefore, the accrual period for this phase II trial is expected to be 13 months. 
The final analysis is predicted to begin approximately 15 months after the trial begins (i.e., as 
soon as the last patient has been observed for 6 weeks). 
13.7 
Data and Safety Monitoring 
The study chair(s) and the study statistician will review the study at regular intervals to identify 
accrual and adverse events. The Alliance Data Safety Monitoring Board (DSMB) is responsible 
for reviewing accrual and safety data for this trial at least twice a year, based on reports provided 
by the Alliance Statistics and Data Management Center (SDMC). 
Required submission of patient demographic data for this study will be submitted automatically 
via OPEN.   
Note: Serious adverse events must be submitted via CTEP-AERS per protocol guidelines. 
13.7.1 Adverse Event Stopping Rules 
The stopping rules specified below are based on the knowledge available at study 
development. We note that the adverse event stopping rule may be adjusted in the event of 
either (1) the study re-opening to accrual or (2) at any time during the conduct of the trial 
and in consideration of newly acquired information regarding the adverse event profile of 
the treatment(s) under investigation. The study team may choose to suspend accrual 
because of unexpected adverse event profiles that have not crossed the specified rule 
below. 
Accrual will be temporarily suspended to this study if at any time we observe adverse 
events considered at least possibly related to study treatment (i.e., an adverse event with 
attribute specified as “possible”, “probable”, or “definite”) that satisfy either of the 
following: 
• 
if 2 or more patients in the first 10 treated patients experience a grade 3 or higher 
adverse event felt to be attributed to the study agent and the event rate is higher in 
the treatment arms than the placebo arm. 
• 
if after the first 10 patients have been treated, 10% of all patients experience a 
grade 3 or higher adverse event felt to be attributed to the study agent and the event 
rate is higher in the treatment arms than the placebo arm. 
We note that we will review grade 4 and 5 adverse events deemed “unrelated” or “unlikely 
to be related,” to verify their attribution and to monitor the emergence of a previously 
unrecognized treatment-related adverse event. 
13.8 
Minority Accrual 
Enrollment will be open to all eligible patients, regardless of race or ethnicity. There is no 
information currently available regarding differential effects of oxybutynin by race or ethnicity, 
and there is no reason to expect such differences to exist. Therefore, although the planned 
analysis will, as always, look for differences in treatment effect based on race and ethnicity, the 
sample size is not increased in order to provide additional power for subset analyses. However, 
it is well known that the incidence of prostate cancer is greater in African American men. Given 
this, an Alliance Health Disparities Committee member was added as a study co-chair to

facilitate appropriate accrual of minority patients. Efforts will be made to accrue a substantial 
number of African American men to this trial.

[PARTICIPANT NAME] [DATE] [PARTICIPANT ADDRESS]  
Dear [PARTICIPANT SALUTATION],  
Thank you for agreeing to take part in this important research study. With the help of people like 
you who participate in clinical trials, we will achieve our goal of effectively treating and ultimately 
curing cancer.  
There are many reasons why individuals choose to participate in a clinical trial. Sometimes it is 
because they want access to a specific medication or because they want to do whatever they 
can to help someone else with cancer.  Whatever your reason for participating, you are making 
a contribution towards finding better treatments and ultimately eliminating this disease for future 
patients. 
You will receive high quality care while participating in this clinical trial. My research staff and I 
will maintain very close contact with you. This will allow me to provide you with the best care 
while learning as much as possible to help you and other participants.  
On behalf of [INSTITUTION] and the Alliance for Clinical Trials in Oncology, we thank you again 
for your participation in this clinical trial and look forward to partnering with you.  
Sincerely, [PHYSICIAN NAME]
