STUDY DURATION 
Screening:  1 to 7 days, Double-blind Period: Subject has up to 
48 weeks to administer study medication, End of Study Visit is 
1-8 days following administration of study drug 
STUDY PROCEDURES 
• Screening activities may be performed in 1 to 7 days [+ 3 days] 
• Double-blind period for up to 48 weeks [+ or – 7 days]  
• Phone contacts monthly [every 28 days + or – 3 days] 
• Pregnancy urine testing for WOCBP monthly [every 28 days + 
or – 7 days] 
• Rescue therapy allowed at or after 20 min post dose 
• One single treatment by subject with symptom recording at 
pre-dose, 5 min, 10 min, 15 min, 20 min, 30 min, and 60 min  
• End of study or early discontinuation Visit 3 is 1-8 days 
post-cluster headache treatment 
CRITERIA FOR 
EVALUATION: 
EFFICACY AND 
SAFETY 
Co-Primary Efficacy Endpoints: 
• 
Proportion of subjects who achieve pain relief at 15 minutes. 
Headache pain is assessed using a 4-point scale (0 = none, 
1 = mild, 2 = moderate, 3 = severe). Pain relief is defined by a 
decrease in pain from severe to mild or none without the use of 
acute rescue medication. 
• 
Proportion of subjects who achieve sustained pain relief from 
15 minutes to 60 minutes post patch application. Sustained 
pain relief requires a pain rating of mild or none at each 
timepoint from 15 minutes to 60 minutes without the use of 
acute rescue medication.   
 
Secondary Efficacy Endpoints: 
• 
Proportion of subjects that achieve pain relief at 5, 10, 20, and 
30 minutes post patch application 
• 
Proportion of subjects that achieve sustained pain relief from 5 
to 60 minutes and from 10 to 60 minutes post patch application 
• 
Proportion of subjects that achieve pain freedom at 10- and 
15-minutes post patch application 
• 
Proportion of subjects that achieve sustained pain freedom 
from 10 to 60 minutes and from 15 to 60 minutes post patch 
application 
• 
Proportion of subjects with rescue therapy use within 
20 minutes post patch application 
• 
Proportion of subjects able to perform their usual daily 
activities as assessed by the subject

SAFETY 
• Incidence of adverse events  
• Physical exam including height and weight 
• Vital signs including blood pressure  
• Serum chemistries and hematological parameters 
• Serum and urine pregnancy for women of child-bearing 
potential 
• 12-lead ECGs  
• Assessment of concomitant medications 
• Investigator visual skin Assessments 
 
STATISTICAL 
METHODS: 
EFFICACY ANALYSIS: 
For the primary efficacy analysis, the proportion of subjects 
achieving pain relief at 15 minutes and sustained pain relief from 
15 minutes to 60 minutes post-dose will be analyzed separately 
using a Cochran Mantel Haenszel test stratified by cluster 
headache subtype (chronic or episodic).  A significance test of the 
treatment difference comparing each C213 dose to placebo will be 
tested at the two-sided 0.05 level, and odds ratios and their 
corresponding 95% confidence intervals will be calculated.  
Secondary endpoints will be analyzed using similar methods.  A 
fixed sequence procedure will be applied to the two C213 arms and 
the primary and secondary efficacy endpoints to adjust for 
multiplicity and to control for overall type I error. 
 
Safety Analyses: 
Adverse events will be summarized overall and by preferred term 
and system organ class.  Adverse events will also be summarized 
by severity and relationship to study drug. Serious AEs and AEs 
leading to discontinuation of study drug will also be summarized.  
All safety data will be listed by subject and parameter, separate 
listings of all abnormal laboratory findings will be provided, and 
clinically significant abnormalities will be recorded as AEs.  
 
Sample Size: 
It is anticipated that 20% of subjects receiving placebo and 55% of 
subjects receiving active treatment will achieve pain relief at 
15 minutes and sustained pain relief from 15 minutes to 60 minutes 
post-dose.  Based on a two-sided chi-square test with continuity 
correction and an alpha level of 0.05, 40 patients/arm will provide 
approximately 80% power to detect this same difference between 
two treatment groups, assuming a 15% dropout rate.

INTRODUCTION 
1.1 
Background C213 for the Acute Treatment of Cluster Headache 
Cluster headache is a debilitating and painful disorder that affects approximately 0.1% of the 
U.S. population.  The excruciating headaches, lasting from 15 minutes to 3 hours and averaging 
45-60 minutes, and are often described as the worst pain the sufferer has ever experienced.  A 
number of acute treatments have been utilized, including injectable triptans, inhaled oxygen and 
neurostimulation.  Perhaps the most important attribute for an acute treatment of cluster 
headache is rapid onset of pain relief or freedom (Rozen et al 2012). 
Zosano is evaluating C213 for the acute treatment of cluster headache (both episodic and 
chronic).  Intranasal and oral zolmitriptan products have been evaluated for the treatment of 
cluster headache, in randomized, placebo-controlled trials and found to be effective.  
Unfortunately, these trials only demonstrated significant efficacy at 30 minutes, which is not 
ideal for these intense and short-lived attacks (Cittadini et al 2006, Bahra et al 2000, Hedlund et 
al 2009). 
Subcutaneous (SC) sumatriptan is also effective for the treatment of cluster headache and 
relieves headache pain in a significant percentage of sufferers (Ekbom et al 1993).  This is likely 
due to the rapid absorption of sumatriptan following injection.  Zosano conducted a 
pharmacokinetic study (CP-2015-007) comparing plasma concentrations of sumatriptan 
following subcutaneous administration with several dose levels of C213 and oral zolmitriptan 
2.5 mg.  The mean plasma concentrations following C213 3.8 mg, oral zolmitriptan 2.5 mg, and 
subcutaneous sumatriptan 6.0 mg are shown below.  Note that the plasma concentrations of 
sumatriptan were divided by 10 to account for differences in potency, as the slide is intended to 
illustrate the comparative pharmacokinetic curves.

By visual inspection, one can see that plasma concentrations of zolmitriptan were detectable very 
quickly after C213 administration, and the time to maximum concentration is similar to 
subcutaneous sumatriptan.  As has been described several times, time to maximum concentration 
of oral zolmitriptan is approximately one hour (Seaber et al 1998), which is far less desirable for 
treating cluster headaches. 
If the rapid absorption of zolmitriptan following C213 administration results in fast relief of the 
severe pain of cluster headache, C213 would be a valuable addition to the therapeutic options 
currently available to cluster headache sufferers.  The goal of this trial is to compare C213 doses 
of 1.9 mg and 3.8 mg (administered as two patches of 1.9 mg) to placebo for the treatment of 
acute cluster headache. 
1.2 
Clinical Pharmacology, Efficacy, and Safety of zolmitriptan and other 
studies of Cluster Headache 
Human Pharmacokinetics 
A Phase 1 study compared the PK of intracutaneous zolmitriptan and its metabolites as well as 
the tolerability of various doses of intracutaneous zolmitriptan to a standard oral dose (2.5 mg) of 
zolmitriptan (CP-2015-007).  Additionally, since onset of effect may be an important attribute of 
the intracutaneous system, the study included a comparison of Tmax values with SC sumatriptan 
6.0 mg.  The study provided preliminary information on the potential advantages of the C213 
system use for the treatment of cluster headaches. 
The calculated key pharmacokinetic parameters for the Zolmitriptan regimens and subcutaneous 
sumatriptan are shown in Table 1.

Perhaps most relevant to the potential utility of this product for the treatment of cluster headache 
is the Tmax for the ZP-Zolmitriptan regimens, showing much more rapid absorption of the 
zolmitriptan from intracutaneous administration than from oral administration. 
Efficacy Measurements 
The efficacy of C213 for the acute treatment of cluster headaches has not been established.  The 
efficacy of zolmitriptan given by oral tablet or nasal spray has been demonstrated in large 
placebo-controlled trials (Rapoport et al 1997, Dawson et al 2005, Dahlof et al 1998).  In a 
meta-analysis of zolmitriptan nasal spray for cluster headache, the authors found that headache 
response was observed at 30 minutes (primary endpoint) in a larger proportion of subjects than 
placebo for both 5 mg and 10 mg doses (48.3% vs 29.5%, P = .0004, and 63.1% vs 29.5%, 
P ≤ .001, respectively).  Furthermore, significantly more subjects were pain free at 30 minutes in 
both dose groups as compared to placebo (34.8% vs 19.3%, P = .007 for 5 mg, and 44% vs 
19.3%, P ≤ .001 for 10 mg).  Similarly, oral zolmitriptan was found to be effective in episodic 
cluster headache at both the 10 mg (59.5%) and 5mg (56.6%) doses versus placebo (42.2%, 
P ≤ 0.01 for both doses) Bahra et al 2000.  The oral formulation was not found to be significantly 
different from placebo in chronic cluster.  
Subcutaneous sumatriptan 6 mg was evaluated in two double-blind, placebo-controlled, 
crossover trials of individuals with cluster headache.  Pain relief rates at 15 minutes for SC 
sumatriptan were 74% and 75% compared with placebo pain relief rates of 26% and 35%.  In 
both trials, SC sumatriptan was significantly more effective than placebo.  Thus, pain relief rates 
appeared higher with the more rapidly absorbed product (Imitrex product information). 
Safety Assessments  
As with efficacy, the safety of various formulations of zolmitriptan has been extensively studied, 
predominantly in migraine patients.   
The safety of oral zolmitriptan at significantly higher doses (and presumably higher plasma 
concentrations) than those proposed for the C213 program, has been evaluated in two large 
placebo-controlled studies of migraine.  Dahlof et al 1998 evaluated 1181 subjects who received 
zolmitriptan doses of 5 mg, 10 mg, 15 mg or 20 mg (more than 200 subjects per dose group).  
The incidence of adverse events was 61%, 75%, 79% and 76% respectively.  \The most 
commonly reported adverse events were asthenia, dizziness, paresthesia and feelings of 
heaviness.  Most of the adverse events were mild or moderate in intensity, not serious, transient 
and resolved without intervention.  The incidence of chest-related adverse events i.e., tightness, 
pain, heaviness, and pressure was low.  Administration of zolmitriptan, even at the highest dose, 
was not associated with significant effects on clinical laboratory tests or ECGs.  
Rapoport et al 1997 compared oral doses ranging from 1 mg to 10 mg of zolmitriptan to placebo 
in 1258 migraine patients and found that efficacy increased as a function of dose, and that all 
doses of zolmitriptan were well-tolerated, although the incidence of adverse events was 
dose-related.

Doses of 25 mg of oral zolmitriptan for the treatment of migraine were evaluated in two 
additional studies (Schoenen et al 1994 and Visser et al 1996) and in both studies this dose was 
well-tolerated. 
Long-Term Safety Studies of Zolmitriptan 
Two large long-term studies have established the long-term safety of oral zolmitriptan and 
intranasal zolmitriptan.  The International Zolmitriptan Study group studied 2058 patients who 
treated 31579 migraines with 5 mg oral zolmitriptan over one year and found the drug to be well-
tolerated.  Dawson et al evaluated 538 patients who treated 20717 attacks over 1 year with 
intranasal zolmitriptan 5 mg, and also found a high degree of tolerability.  Therefore, the 
long-term safety of frequent administration of zolmitriptan administered from two different 
formulations has been well established.

Safety Results of Protocol CP-2016-001 
Study CP-2016-001 was a dose ranging study comparing the safety and efficacy of M207/C213 
to placebo in the acute treatment of migraine attacks.  365 subjects were enrolled in this study.  
No serious adverse events occurred in the efficacy and safety study CP-2016-001 in subjects 
with migraine.  Adverse events including investigator and subject-reported dermal events at the 
patch site were generally mild and transient.  Treatment-emergent adverse events that occurred in 
two or more subjects summarized by System Organ Class/Preferred Term are shown in Table 2, 
and Investigator Dermal Adverse Events are shown in Table 3.

Study Rationale and Choice of Design 
C213 is a novel formulation of zolmitriptan for intracutaneous delivery, which when 
administered results in rapid systemic absorption of zolmitriptan and time to maximum 
concentration of plasma zolmitriptan of approximately 15 minutes.  This product was evaluated 
in a previous migraine trial (CP-2016-001), and the 3.8 mg dose was superior to placebo for both 
co-primary endpoints.  The 1.9 mg dose was superior to placebo for 1 of 2 co-primary endpoints 
(pain freedom at 2 hours).  Tolerability was good, and the most common adverse reactions were 
application site reactions, that all resolved over a course of hours to days. 
Cluster headaches are severe, debilitating and exquisitely painful, but the attacks are of shorter 
duration than in migraine.  Given the characteristics of the attacks, any drug administered to 
abort the attacks must be rapidly absorbed to be of benefit.  Previous trials of subcutaneous 
sumatriptan have demonstrated that a rapidly absorbed triptan can relieve the pain associated 
with a cluster attack.  Thus, C213 with observed Tmax ranging from 2-30 minutes seen in a 

Zosano Pharma Corporation 
 
Protocol No. CP-2019-001v4

previous Phase 1 study, may be absorbed rapidly enough to produce systemic levels of 
zolmitriptan, sufficient to relieve a cluster headache attack. 
The doses of C213 used in this study are 3.8 mg, that was found to be effective in a previous 
migraine efficacy trial and 1.9 mg, that was effective for pain reduction in the same trial.  There 
is anecdotal clinical evidence that lower doses of injected triptans may be effective for cluster 
headache attacks. 
Sample size determination was estimated based on the characteristics of C213 and the results of 
previous trials of pharmacologic agents for the treatment of cluster headache.  The only product 
approved for treating cluster headache is subcutaneous sumatriptan, and the effect size in those 
trials was significant.   However, the trials were crossover designs utilizing paper diaries 
conducted in the 1990s.  The more recent trials with zolmitriptan (particularly nasal spray) had 
smaller effect sizes, perhaps due to slower absorption than seen with SC sumatriptan.  C213 has 
pharmacokinetics more similar to SC sumatriptan than the zolmitriptan formulations.  Therefore, 
we estimated the effect size of C213 to be somewhere between that of SC sumatriptan and that of 
intranasal zolmitriptan.

This is a randomized, double-blinded, placebo-controlled study.  Subjects who have consented 
and meet the entry criteria will be randomized to receive one of three blinded treatments.   
Qualified subjects will randomize to the double-blind treatment period at Day 1 and will have up 
to 48 weeks to confirm and treat a cluster headache.  Using the eDiary to confirm the subject is 
experiencing a cluster headache, subjects will self-administer the patches and continue to 
respond to questions in the eDiary for 1-hour post treatment administration.

3.2.4 
Eligibility Criteria for Randomization 
To be eligible for randomization and the double-blind period, subjects must meet all inclusion 
and exclusion criteria.  In addition, the following must be confirmed on the day of 
randomization: 
1. Demonstrated ability to properly use the eDiary 
2. Willing to enter eDiary data to determine if he/she is experiencing a qualifying cluster 
headache attack and complete the eDiary questions after applying the patches 
3. Demonstrated ability to apply the demonstration study drug patches 
4. Confirmation of continuing good general health, or stable non-serious disease that in the 
opinion of the Investigator will not place the subject at risk 
 
3.2.5 
Prior and Concomitant Medications Allowed During the Study 
Medications that are considered necessary for the subject’s welfare and are not specifically 
prohibited (Section 6.2.10), may be given at the discretion of the investigator.  The 
administration of such medication must be recorded in the appropriate source document and in 
the electronic case report form (eCRF) for the duration of the study.   
For the cluster headache to be qualifying for study medication, no medications specifically taken 
for the subject’s headache symptoms are allowed within 24 hours prior to onset of the current 
cluster headache symptoms. If rescue therapy is required by the subject, rescue therapy other 
than a triptan or ergot is permitted at or after 20 minutes post study drug administration.   
Oxygen will be provided in an “E” cylinder (680L), with a flow-rate adjustable regulator and a 
non-rebreather facemask.  
3.2.6 
Early Termination  
3.2.6.1 
Withdrawal of Subjects 
Subjects may be withdrawn from treatment or from the study for the following reasons: 
• At their own request or at the request of their legally authorized representative; 
• If, in the investigator’s opinion, continuation of treatment would be detrimental to the 
subject’s well-being; 
• If the subject experiences any AE believed to be possibly or probably related to study 
drug and severe enough to warrant withdrawal of treatment; 
• If the subject starts and continues to use a prohibited drug, as listed in Section 6.2.10; or  
• If the subject is non-compliant with the study drug and dosing schedule, or any other 
requirement of this protocol.

For all subjects who are withdrawn from the study, the reason must be recorded on the 
appropriate source document and on the appropriate eCRF.  The subject must be followed up to 
establish whether the reason was an AE, and, if so, this must be reported in accordance with the 
procedures in Section 8.3.  Subjects with ongoing systemic and skin AEs at study termination 
will be followed until all significant changes have resolved or become medically stable.   
To the extent possible, all examinations scheduled and all data normally collected at completion 
of the study (the final study visit) must be performed on all subjects who receive study drug, but 
do not complete the study according to protocol (see Section 6.1.4).  This can be done until study 
closure but preferably as close as possible to the time of the subject’s early termination.   
The investigator must make at least three documented attempts (phone, email, etc.) to contact 
subjects lost to follow-up up until the time of database lock.  This includes one certified letter 
sent to the subject’s primary place of residence.  A copy must be maintained in the source 
documentation. 
3.2.6.2 
Replacement of Subjects 
Subjects who discontinue after being randomized will not be replaced.  
3.2.6.3 
Premature Discontinuation of the Trial  
The Sponsor has the right to terminate this study at any time.  Reasons for termination of the 
study may include, but are not limited to, the following: 
• The Health Authority or IRB/EC terminates the study; 
• The incidence or severity of AEs in this or other studies indicates a potential hazard to 
subjects; 
• Subject enrollment is unsatisfactory; 
• The trial is not conducted in accordance with the procedures defined in the approved 
protocol (i.e., protocol deviations, failure to ensure the quality of the data collected); 
• New information on the study drug warrants study termination;  
• The discretion of the Sponsor 
 
The IRB/Ethics Committee(s) and Health Authorities should be informed about a premature 
discontinuation of the trial.

STUDY TREATMENTS 
4.1 
Identity of Investigational Products 
4.1.1 
C213 
The C213 patches will be manufactured by Zosano Pharma in Fremont, CA (see Investigator’s 
Brochure for more information).   
4.1.2 
Comparator Product:  ZP-Placebo 
The Placebo will be manufactured by Zosano Pharma.  The placebo patch is a single use, 3 cm2 
Placebo (intracutaneous microneedle) system that contains no active ingredients. 
The Placebo patch is supplied and packaged in an identical fashion as the C213 1.9 mg coated 
patch thereby maintaining the blinding. 
4.1.3 
Product Description and Patch Application 
The Zosano C213 Microneedle System is a novel drug delivery technology which consists of a 
disposable titanium patch centered on an adhesive backing with microneedles that are dry-coated 
with the drug product formulation, and a reusable handheld applicator that ensures that the patch 
is applied with a defined application speed and energy to the site of administration. 
The C213 System is a proprietary disposable patch and a reusable applicator.  The zolmitriptan-
coated titanium microneedle array (3 cm2 array) is attached to a 5 cm2 adhesive patch.  A 
magnified image of the zolmitriptan-coated microneedles is shown in Figure 2.  The patch 
system is composed of several parts.  The patch is mounted inside a polycarbonate plastic ring 
with a co-molded desiccant (Figure 3). 
The completed system is packaged in a nitrogen purged foil cup.  The reusable applicator is 
shown in Figure 3 and Figure 4 with a lock-out function to avoid accidental firing.  The 
applicator provides a spring-driven piston to apply the patch with consistent impact energy of 
0.26 Joules.  The user presses the handheld reusable applicator onto the patch ring assembly for 
attachment, then the applicator is un-locked by twisting the cap.  The user applies the patch by 
pressing the applicator/patch ring assembly onto the skin site and holding it to the arm for 
3 seconds (Figure 4).  The system was used in the Zosano Pharma Phase 1 study CP-2015-007, 
conducted in Australia under Clinical Trials Authorization (CTA), two phase 1 PK studies, 
CP-2018-002 and CP-2019-001 conducted in the US, a Phase 2 efficacy study CP-2016-001 and 
a long-term safety study CP-2017-001, conducted in the US.  The intended regimens for this 
clinical study will be 1.9 mg plus one placebo patch, two patches of 1.9 mg (3.8 mg total dose), 
or two placebo patches delivered to the upper arm.

4.2 
Method of Assigning Subjects to Treatment Group 
Approximately 120 subjects will be randomly assigned to receive one of the three treatments in a 
1:1:1 ratio: C213 1.9 mg administered as one active and one placebo patch, C213 3.8 mg 
administered as two active patches, or placebo administered as two placebo patches.  
Randomization will be stratified by study center and cluster headache subtype (chronic or 
episodic).  Zosano will employ RTSM randomization system for randomization and subsequent 
clinical trial material (CTM) kit assignments.  A contract research organization will be 
responsible for generating the randomization schedule.   
At randomization (Day 1), once it has been established that a subject qualifies for the study, 
study staff will log in to Medidata using appropriate credentials and input subject-specific 
information.  In accordance with the randomization schedule, the RTSM will assign the 
randomization number and the unique CTM kit number to the subject.  Each subject must be 
given only the CTM kit assigned by the RTSM randomization system.  The study staff will 
document the kit number assigned in the eCRF.  Subjects are to be randomized in the order in 
which they qualify from the screening phase for inclusion in the study. 
4.3 
Dose, Dose Schedule, and Route of Administration 
The study drug will be dispensed only to qualified, randomized subjects included in this study in 
accordance with the eligibility criteria specified in the study protocol. 
When a subject experiences a qualifying headache (as confirmed by answering questions in the 
eDiary), the subject will self-administer the study drug.  Subjects will be trained on how to 
administer the patches using the C213 applicator supplied in the kit. 
4.4 
Packaging, Labeling, and Receipt of Supplies 
In this study, C213 active and placebo patches will be double-blinded. 
The C213 patches (active or placebo) are individually packaged in cups.  Two patches per dose 
and one applicator will be packaged in a CTM kit based on the randomization schedule.  The kit 
labels will contain at minimum the manufacturer’s name, CTM kit number, storage conditions, 
and a statement indicating that the study drug is for investigational use only.

The on-site pharmacist or designee will inventory and acknowledge receipt of all shipments of 
study drug.  The study site personnel will access the RTSM in Medidata to confirm receipt of 
each study drug shipment. 
4.5 
Study Drug Stability, Storage, and Retention 
C213 patches are stable at 20-25°C.  The patches and handheld applicators, packaged in 
individual subject kits, should be stored at controlled room temperature (20-25◦C/68◦F-77◦F).  All 
CTM kits must be kept in a locked area with access restricted to designated study personnel.  
Sites do not need to report excursions in the range of 15°C to 20°C.  Sites must report all 
excursions under 15°C and over 25°C.  
4.6 
Study Drug Kit Assignment, Dispensation, and Accountability 
A kit will be supplied to each subject based on the kit number assigned by the RTSM in 
Medidata. The pharmacist or designee will record the CTM kit number dispensed to each subject 
on the drug accountability record.  The designated site monitor will periodically check the 
supplies of CTM to ensure accountability of used applicators and unused kits. Final study drug 
accountability will be completed after the last subject visit.  All drug accountability records will 
be filed in the site file and TMF as appropriate.  The kits dispensed and used for each subject 
must be documented. Any discrepancies must be documented. 
4.7 
System Performance  
A C213 Site User’s Manual will be provided.  An applicator associated with field observations of 
atypical appearance or system performance that cannot be resolved after consulting the C213 
Site User’s Manual should be returned directly to Zosano Pharma following the instructions 
provided in the manual.  A description of the field observation should accompany the shipment. 
Only defective applicators will be returned to Zosano.   At the end of the study, all unused kits 
will be dispositioned per Zosano Pharma instructions. 
4.8 
Medication Compliance 
The investigator will emphasize the importance of correctly self-administering the study 
medication once a qualifying cluster headache is confirmed through the eDiary.  Subjects will be 
instructed to bring the following items to the final clinic visit following administration of their 
dose: 
• eDiary 
• C213 applicator 
• Any unused C213 patches  
 
Subjects may discard used patches.  Date and time of dose and information regarding the 
subject’s study drug administration will be recorded in the eDiary.

EFFICACY AND SAFETY ANALYSIS VARIABLES 
5.1 
Efficacy 
The co-primary efficacy endpoints are the proportion of subjects who achieve pain relief at 
15 minutes and the proportion of subjects who achieve sustained pain relief from 15 minutes to 
60 minutes.  Headache pain is assessed using a 4-point scale (0 = none, 1 = mild, 2 = moderate, 
3 = severe).  Pain relief is defined by a decrease in pain from severe to mild or none without the 
use of acute rescue medication.  Sustained pain relief requires a pain rating of mild or none at 
each timepoint from 15 minutes to 60 minutes without the use of acute rescue medication.   
The secondary efficacy endpoints for this study are:  
• Proportion of subjects that achieve pain relief at 5, 10, 20, and 30 minutes post patch 
application 
• Proportion of subjects that achieve sustained pain relief from 5 to 60 minutes and from 
10 to 60 minutes post patch application 
• Proportion of subjects that achieve pain freedom at 10 minutes and 15 minutes post patch 
application 
• Proportion of subjects that achieve sustained pain freedom from 10 to 60 minutes and 
from 15 to 60 minutes post patch application 
• Proportion of subjects using rescue therapy within 20 minutes post patch application 
• Proportion of subjects able to perform their usual daily activities as assessed by the 
subject 
 
5.2 
Safety 
Safety assessments will be initiated after the informed consent form (ICF) has been signed and 
will conclude when the post-study procedures are completed (or early discontinuation).   
Safety will be assessed through the following: 
• Incidence of adverse events 
• Physical exam including height and weight 
• Vital signs including blood pressure 
• Clinical laboratory determinations including coagulation studies 
• Serum pregnancy and urine pregnancy for women of child-bearing potential 
• 12-lead ECGs

6.1.3 
Double-Blind Treatment Phase: Day 1 through up to 48 Weeks [336 Days + or – 
7 days]  
Subjects will have up to 48 weeks to confirm and treat a qualifying cluster headache. Subjects 
will be instructed to complete the eDiary at the time of a suspected cluster headache.  Once the 
eDiary confirms that the subject has a “qualifying” cluster headache, the subject will follow the 
steps provided to self-administer the study drug.   
6.1.3.1 
Day 1 through Week 48: Treatment of a Qualifying Cluster Headache 
The following constitutes a cluster headache that qualifies for treatment with study drug: 
• Severe unilateral orbital, supraorbital and/or temporal pain 
• Either or both of the following:  
1) at least one of the following symptoms or signs, ipsilateral to the pain:  
 conjunctival injection and/or lacrimation  
 nasal congestion and/or rhinorrhea  
 eyelid edema  
 forehead and facial sweating  
 miosis and/or ptosis  
2) a sense of restlessness or agitation 
The following procedures are to be performed by the subject for a cluster headache from Day 1 
through 48 weeks of the double-blind period: 
• Using the eDiary, the subject will record the following to confirm the headache meets the 
qualifications for a cluster headache: 
Cluster headache symptoms and pain assessment 
• Once the qualifying cluster headache has been confirmed, subject self-administers the 
study drug patches.  Subjects will apply two patches to the upper arm.  
• Subject will continue to record the following in the eDiary, post self-administration of the 
patches at 5 min, 10 min, 15 min, 20 min, 30 min and 60 mins.

Study Procedures 
6.2.1 
Informed Consent 
Each study participant (or legally authorized representative) will be required to read, sign, and 
date the current institutional review board/independent ethics committee (IRB/IEC) approved 
version of the ICF.  The consent process should also be documented in the study site’s source 
documents.  Informed consent must be obtained prior to performing any study-specific 
procedures.  Both the participant and the study staff member who participated in the consent 
discussion with the participant must sign and date the ICF.  Each study participant will be given 
a copy of the ICF.  All participants will have an opportunity to ask questions before signing the 
ICF, and the study staff member who obtains consent will probe the subject to ascertain 
understanding of the elements of consent. 
6.2.2 
Inclusion/Exclusion Criteria 
All inclusion criteria and none of the exclusion criteria must be satisfied prior to randomization 
and assignment of a CTM kit number to the subject and the start of study drug dosing.   
6.2.3 
Medical History, Substance Use, Cluster Headache History and Demographics 
Demographic information and a medical history, including history of menopausal status, will be 
obtained during screening.  The medical history should include all current conditions, including 
recent illnesses and relevant past medical history.  Subjects will be asked about current use of 
illicit drugs, nicotine containing products, and alcohol.  Information will also be obtained on the 
subject’s history of cluster headache therapy.   
6.2.4 
Randomization 
Randomization will be conducted at Day 1 after verifying that the participant meets all inclusion 
criteria and has none of the exclusion criteria.  Participants who meet the study eligibility criteria 
and give informed consent will be randomized to one of three doses (1.9 mg, 3.8 mg, or 
placebo). 
6.2.5 
Physical Examination 
A PE will be performed during screening for inclusion, at Day 1 and End of Study (or early 
discontinuation).  The physical exam will include, but is not limited to, HEENT, dermatologic 
(investigator skin assessment), brief neurological, general appearance, lymph nodes, 
cardiovascular, respiratory, gastrointestinal and musculoskeletal examination. 
6.2.6 
Height and Weight 
Subjects will have both height and weight measured at screening, and weight only will be 
collected at Day 1, and the End of Study visit (or early discontinuation).  The subject must not 
wear shoes during the height measurement.

The subject should wear light clothing and no shoes during weight measurements.  Subjects 
should be weighed on the same clinic scale during this study.  
6.2.7 
Vital Signs 
All subjects will have vital signs (temperature, RR, BP, and HR) measured at screening and all 
subsequent visits.   
Whenever possible, vital sign measurements will be taken before any blood samples are taken. 
6.2.8 
Clinical Laboratory Tests 
Blood samples will be collected for clinical laboratory tests at screening and at the End of Study 
visit (or early discontinuation).  Subjects must be fasting (i.e., nothing by mouth for at least 
4 hours before the visit; drinking water during the 4-hour fast before clinical laboratory 
assessments is permitted).  All samples will be processed by a central laboratory.  The following

Laboratory tests will be performed at screening and at the End of Study visit (or early 
discontinuation).  Clinically significant abnormal values at screening may be repeated to confirm 
eligibility.  Pregnancy tests will be performed on all women of child-bearing potential every 
month [+ or – 7 days] after randomization to ensure no pregnancy prior to study drug 
administration.  
The urine drug abuse screen will be performed at screening and will test for amphetamines, 
barbiturates, cocaine, phencyclidine (PCP), and meth/amphetamines. 
The central laboratory will provide a laboratory manual and appropriate supplies (containers and 
labels).  Laboratory values that are out of range will be identified and may be repeated at the 
investigator’s discretion with sponsor approval.  The investigator will determine if any out-of-

range laboratory values that emerge during treatment are clinically significant and if so, record 
these on the appropriate source document and on the AE eCRF page if applicable.  All clinically 
significant out-of-range laboratory values will be followed until they return to normal or become 
medically stable.  
6.2.9 
Twelve-Lead Electrocardiogram 
The ECG, done at screening and at the End of Study visit (or early discontinuation), and will be 
sent to a central ECG laboratory for interpretation.  ECG equipment and an ECG manual will be 
provided by the central ECG lab. 
Any clinically significant abnormality noted on the screening ECG will be recorded on the 
appropriate source document and will result in exclusion of the subject from this study.  The 
investigator may refer the subject for further evaluation and will continue to follow the subject’s 
condition until the changes have resolved or the subject is medically stable.  
6.2.10 
Previous, Concomitant and Prohibited Medications 
Concomitant medications will be recorded on the appropriate source document and on the 
appropriate eCRF at all visits including screening, randomization day, and end of study (or early 
discontinuation).  All previous and concomitant medications taken within 90 days prior to the 
screening visit must be recorded in the source document and eCRF.  When new medications are 
started and come to the attention of the investigator between scheduled visits, they will be 
recorded that day on the appropriate source document and on the appropriate eCRF.  
No triptans or ergots are allowed within 24 hours prior to onset of current cluster headache 
symptoms.  If rescue therapy is required by the subject, rescue therapy other than a triptan or 
ergot is permitted at or after 20 minutes post study drug administration.   Ergots and triptans may 
be resumed 24 hours after dosing with study medication. 
No lotions, ointments or powders applied to the skin immediately before (within an hour) or for 
24 hours after applying the patches are allowed.

duration.  New systemic and skin AEs will be recorded on the appropriate source document and 
eCRF. 
6.2.12 
Investigator Skin Assessment 
The investigator will perform a visual skin assessment of bruising, erythema, and edema at the 
randomization visit and at the End of Study (or early discontinuation) visit.  Any adverse events 
including application site reactions will be documented on the appropriate eCRF page and must 
be followed until resolution or medically stable.  
At the End of Study (or early discontinuation) visit, the entire surface area of the outer upper arm 
where the two patches were applied will be assessed for the following skin signs or symptoms.   
Any findings with an intensity rating of 1 (Mild intensity), 2 (Moderate intensity), or 3 (Severe 
intensity) must be recorded as an adverse event in the eCRF and followed to resolution.  The 
investigator will use the definitions of AE Severity Ratings for Mild, Moderate, Severe, 
Life-Threatening (Section 8.2.1.3) to assess the Severity of the AE. 
For further instructions, photographs and descriptors are in Photograph and Appendix 1

STATISTICS 
A full description of the statistical analyses to be performed at study completion will be provided 
in a Statistical Analysis Plan (SAP), which will be finalized prior to database lock and 
unblinding of the study. 
Unless otherwise noted, significance tests of treatment differences will be tested at the two-sided 
0.05 level. 
7.1 
Analysis Populations 
Modified Intent-to-Treat (mITT) Population 
All randomized patients who have a qualifying headache and at least one post-application pain 
score recorded within the first 15 minutes post-application will be included in the mITT 
population.  This is the primary population for efficacy analyses and patients will be analyzed 
based on their randomized treatment.   
Safety Population 
The safety population will include all patients who received any amount of study drug. All safety 
analyses will be performed using this population, analyzed as treated.    
7.2 
Estimate of Sample Size 
It is anticipated that 20% of subjects receiving placebo and 55% of subjects receiving active 
treatment will achieve pain relief at 15 minutes and sustained pain relief from 15 minutes to 60 
minutes post-dose.  Based on a two-sided chi-square test with continuity correction and an alpha 
level of 0.05, 40 subjects/arm will provide approximately 80% power to detect this same 
difference between two treatment groups, assuming a 15% dropout rate. 
   
7.3 
Demographic and Baseline Characteristics 
Demographic and baseline characteristics such as age, gender, race/ethnicity, height, and weight, 
will be summarized by treatment group using descriptive statistics.  Medical History will be 
coded using MedDRA and summarized by SOC and Preferred Term using frequency counts.  
Baseline disease characteristics will also be summarized. 
7.4 
Efficacy Analysis 
7.4.1 
Primary Analysis  
The co-primary efficacy endpoints are the proportion of subjects who achieve pain relief at 
15 minutes and the proportion who achieve sustained pain relief from 15 minutes to 60 minutes 
post patch application.  These two endpoints will be analyzed separately using a Cochran Mantel 
Haenszel test stratified by cluster headache subtype (episodic or chronic) and will utilize the 
mITT population.  A significance test of the treatment difference comparing each C213 dose to

Page 48 of 68 
 
placebo will be tested at the two-sided 0.05 level, and odds ratios and their corresponding 95% 
confidence intervals will be calculated.  Headache pain will be assessed using a 4-point scale 
(0 = none, 1 = mild, 2 = moderate, 3 = severe), with pain relief defined by a decrease in pain 
from severe to mild or none without the use of acute rescue medication.  Sustained pain relief 
requires a pain rating of mild or none at each timepoint from 15 minutes to 60 minutes without 
the use of acute rescue medication.  Handling of missing data as well as sensitivity analyses will 
be described in the SAP. 
7.4.2 
Secondary Analyses 
Secondary endpoints will be analyzed using similar methods as the primary endpoints and will 
utilize the mITT population. 
To adjust for multiplicity and to control for overall type I error, a fixed sequential testing 
procedure will be applied to the primary analyses for the two C213 arms and the secondary 
efficacy analyses.  If the primary efficacy analyses for the 3.8 mg arm both produce a result that 
is statistically significant at the 0.05 level, a significance level of 0.05 will be used for the 
primary analyses of the 1.9 mg arm and for the secondary efficacy analyses in an ordered 
fashion.  If any subsequent analysis does not produce a statistically significant result at the 0.05 
level, then the remaining analyses will automatically be considered non-significant.  The order of 
testing for each endpoint and each C213 dose group will be provided in the SAP. 
7.5 
Safety Analysis 
Safety analyses will be performed using the Safety population.  Safety will be assessed by: 
• Incidence of adverse events 
• Physical exam including height and weight 
• Vital signs including blood pressure 
• Clinical laboratory determinations including serum chemistries and hematological 
parameters 
• Pregnancy testing for women of child-bearing potential 
• 12-lead ECGs  
• Assessment of concomitant medications 
• Investigator visual skin assessments 
 
Adverse events will be coded using the latest version of MedDRA and will be summarized 
overall and by preferred term and system organ class.  Adverse events will also be summarized 
by severity and relationship to study drug.  Serious AEs and AEs leading to discontinuation of 
study drug will also be summarized.

ADVERSE EVENTS 
All systemic and skin AEs, regardless of treatment group or suspected causal relationship to the 
investigational products, will be reported as described in the following sections. 
For all systemic and skin AEs, the investigator must obtain adequate information both to 
determine the outcome of the AE and to assess whether it meets the criteria for classification as a 
SAE (see Section 8.2.1.1) requiring immediate notification (within 24 hours) to the Medical 
Monitor (MM) and Pharmacovigilance Group (PV) by completing a SAE Report Form.  
Sufficient information should also be obtained by the investigator to determine the causality of 
the AE, since he/she is required to assess causality.  For systemic and skin AEs with a causal 
relationship to the investigational product, including all application site reactions, investigator is 
required to follow-up until the event or its sequelae resolve or stabilize at a level acceptable to 
the investigator, and Zosano Pharma concurs with that assessment. 
Pregnancy:  In the event that a pregnancy occurs, it will not be considered an AE but requires 
notification within 24 hours of investigator awareness to the Medical Monitor and 
Pharmacovigilance Group by completing a Pregnancy Report Form.  The investigator will follow 
the pregnancy through the time of birth and report the outcome.  Information about the subject’s 
newborn or subject’s pregnant partner will be followed for up to 1 month after the birth. 
8.1 
Reporting Period 
Collection of systemic and skin AEs will be initiated after the ICF has been signed and will 
conclude when the post-study procedures are completed (or Early Discontinuation).  The 
investigator will also report to the Medical Monitor and Pharmacovigilance any SAEs that come 
to his/her attention that occur within 30 days after study drug administration.   
8.2 
Adverse Event Definitions 
8.2.1 
Adverse Events (Adverse Experiences) 
An AE is any untoward medical event that occurs in a clinical investigation, where a subject is 
administered a medicinal (investigational) product or medical device, and which does not 
necessarily have a causal relationship between the event and the treatment.  An AE can be any 
unfavorable and unintended sign or symptom, including clinically significant abnormal 
laboratory result, concomitant illness, or worsening of an existing medical condition. 
A Treatment Emergent Adverse Event (TEAE) is an event that emerges during treatment having 
been absent pre-treatment or worsens relative to the pre-treatment state. 
Collection of systemic and skin AEs will be initiated after the ICF has been signed and conclude 
when the post-study procedures are completed (or Early Discontinuation).  This includes the time 
between screening and the first dosing.

Abnormal laboratory tests that are clinically significant, as determined by the investigator, 
should be reported as AEs if: 
• the test result is associated with accompanying symptoms;  
• the test result requires additional diagnostic testing or medical/surgical intervention;  
• the test result leads to discontinuation from the study, significant additional concomitant 
drug treatment, or other therapy; 
• the test result is considered to be an AE by the investigator or sponsor. 
 
Merely repeating an abnormal test, in the absence of any of the above conditions, does not 
constitute an AE.  Any abnormal test result that is determined to be an error does not require 
reporting as an AE. 
8.2.1.1 
Serious Adverse Event Definitions 
A serious adverse event (SAE) or reaction is any untoward medical occurrence that at any dose:  
• Results in death; 
• Is life-threatening (immediate risk of death); 
• Requires inpatient hospitalization or prolongation of existing hospitalization (Emergency 
department outpatient visits for an event not fulfilling any of the other definitions of SAE 
given do not qualify as hospitalization.  If an emergency department visit leads to 
inpatient hospitalization, it would qualify as an SAE.); 
• Results in persistent or significant disability/incapacity; or 
• Is a congenital anomaly/birth defect. 
• Other important medical events that may not result in death, be life-threatening, or 
require hospitalization may be considered serious when, based upon appropriate medical 
judgment, they may jeopardize the patient or subject and may require medical or surgical 
intervention to prevent one of the outcomes listed in this definition.  Examples of such 
medical events include allergic bronchospasm requiring intensive treatment in an 
emergency room or at home, blood dyscrasias or convulsions that do not result in 
inpatient hospitalization, or the development of drug dependency or drug abuse. 
 
Definition of disability:  A substantial disruption of a person’s ability to conduct normal life 
functions.

Protocol No. CP-2019-001v4

Life-threatening SAE:  Any AE that places the subject, in the view of the investigator, at 
immediate risk of death from the reaction as it occurred (i.e., it does not include a reaction that 
had it occurred in a more severe form, might have caused death). 
Hospitalization:  AEs reported from clinical studies resulting in hospitalization or prolongation 
of hospitalization are considered serious.  Hospitalization does not include the following: 
• Rehabilitation facilities; 
• Hospice facilities; 
• Respite care (e.g., caregiver relief); 
• Skilled nursing facilities; 
• Nursing homes; 
• Routine emergency department admissions; or 
• Same day surgeries (as outpatient/same day/ambulatory procedures). 
 
Hospitalization or prolongation of hospitalization in the absence of a precipitating, clinical AE is 
not in itself an SAE.  Examples include: 
• Admission for treatment of a preexisting condition not associated with the development 
of a new AE or with a worsening of the preexisting condition (e.g., for work-up of 
persistent pre-treatment lab abnormality); 
• Social admission (e.g., subject has no place to sleep);

documentation for the entire protocol and/or for the individual subject. 
 
8.2.1.2 
Unexpected Adverse Event 
An unexpected AE is any AE the nature or severity of which is not consistent with the applicable 
product information (e.g., current investigator’s brochure); or if an investigator’s brochure is not 
required or available, the specificity or severity of which is not consistent with the risk 
information described in the general investigational plan or elsewhere in the current application, 
as amended.

8.2.1.3 
Severity Ratings 
The investigator will evaluate the severity of each AE using the following definitions: 
Mild - event may be noticeable to subject; does not influence daily activities; usually does not 
require intervention. 
Moderate - event may be of sufficient severity to make a subject uncomfortable; performance of 
daily activities may be influenced; intervention may be needed. 
Severe - event may cause severe discomfort; usually interferes with daily activities; subject may 
not be able to continue in the study; treatment or other intervention usually needed. 
Life-Threatening - Event that, in the view of the investigator, places the subject at immediate 
risk of death from the reaction as it occurred (i.e., it does not include a reaction that, had it 
occurred in a more severe form, might have caused death). 
Note the distinction between the severity and the seriousness of an AE.  A severe event is not 
necessarily an SAE.  For example, a headache may be severe (interferes significantly with 
subject's usual function) but would not be classified as serious unless it met one of the criteria for 
SAEs, listed above.  Additionally, an SAE of abdominal pain in an elderly patient that results in 
hospitalization to rule out diverticulitis may be mild, whereas severe abdominal pain (that 
interferes with most daily activities) in a younger, stoic patient may not result in hospitalization, 
and thus be a severe non-serious AE.  
8.2.1.4 
Relationship to Study Drug 
The investigator’s assessment of causality must be provided for all systemic and skin AEs 
(serious and non-serious).  An investigator’s causality assessment is the determination of 
whether there exists a reasonable possibility or likelihood that the investigational product caused 
or contributed to an AE.  If the investigator’s final determination of causality is unknown and the 
investigator does not know whether the investigational product caused the event, then the event 
will be handled as “related to investigational product” for reporting purposes.  Thus, it is 
imperative that all initial SAE reports include an assessment of causality.  If the investigator's 
causality assessment is "unknown but not related to investigational product", this should be 
clearly documented on study records. 
In addition, if the investigator determines an SAE is associated with study procedures, the 
investigator must record this causal relationship in the source documents and eCRF, as 
appropriate, and report such an assessment in accordance with the SAE reporting requirements, 
if applicable. 
After careful medical consideration, the investigator will evaluate the relationship of each AE to 
study drug applying the following definitions:  

Zosano Pharma Corporation 
 
Protocol No. CP-2019-001v4 
 
 
 
15 April 2020

Page 54 of 68 
 
Probably Related 
An AE that is likely due to the use of the study drug.  The relationship in time is suggestive.  An 
alternative explanation is unlikely, e.g., concomitant drug(s), concurrent illness(es). 
Possibly Related 
An AE that might be caused using the study drug.  The relationship in time is reasonable; 
therefore, a causal relationship cannot be excluded.  An alternative explanation is inconclusive, 
e.g., concomitant drug(s), concurrent illness(es), but unlikely. 
Not Related 
An AE that is judged to be clearly due only to extraneous causes (disease or illness, environment, 
etc.).   
The cause must be noted on the appropriate source document and on the AE eCRF page. 
8.3 
Documentation and Reporting of Adverse Events by Investigator 
Each AE is to be assessed to determine if it meets the criteria for an SAE.  If an SAE occurs, 
expedited reporting will follow local and international regulations, as appropriate. 
All AEs, both expected and unexpected, occurring during this clinical trial must be recorded on 
the AE page of the eCRF.  AEs will be described in precise medical terms, along with the date 
and time of onset and the date and time of resolution, action taken and outcome.  In order to 
avoid vague, ambiguous or colloquial expressions, the AE should be recorded in standard 
medical terminology rather than the subject’s own words.  Whenever possible, the Investigator 
should group together into a single term signs and symptoms which constitute a single diagnosis.  
Each AE is to be evaluated for duration, severity, seriousness and causal relationship to the 
investigational drug.  The severity of the AE and its relationship to the test product will be 
assessed by the Investigator.  When reporting SAEs, the AE form of the eCRF and the SAE form 
must be completed in a consistent manner.  For example, the same AE term should be used on 
both forms.  
8.3.1 
Reporting Requirements for Serious Adverse Events 
ALL SERIOUS ADVERSE EVENTS, REGARDLESS OF CAUSE(S) OR RELATIONSHIP 
TO STUDY DRUG, MUST BE REPORTED IMMEDIATELY TO PHARMACOVIGILANCE 
GROUP (PV) AND MEDICAL MONITOR (MM) BY TELEPHONE (24/7 Safety Line), FAX, 
OR EMAIL (Contact info are provided in Section 8.5). 
All SAE reporting will adhere to 21 CFR 312.32 for IND safety reporting, applicable FDA and 
ICH-GCP regulations. 
If an SAE occurs, PV and MM are to be notified within 24 hours of awareness of the event by 
the investigator.  In particular, if the SAE is fatal or life-threatening, notification to PV and MM

must be made immediately, irrespective of the extent of available AE information.  This 
timeframe also applies to additional new information (follow-up) on previously forwarded SAE 
reports.  An initial assessment of causality must be included in all SAE reports. 
To report an SAE, the investigator must complete the SAE Report Form, and to report a 
pregnancy, the investigator must complete the Pregnancy Report Form.  Occurrence of any 
SAE/pregnancy must be reported immediately (within 1 working day) once the investigative site 
has knowledge of the event.  The investigator must also provide any relevant information 
regarding the SAE and respond to requests for follow-up in a timely manner.  All SAEs will also 
be reported on the AE eCRF page and concomitant medications administered in association with 
the SAE will be documented on the appropriate eCRF. 
If an SAE occurs and comes to the attention of the investigator after study termination within 
30 days of the last dose of study drug(s), it must be reported immediately to the sponsor in the 
same way as the SAEs occurring during the study. 
8.3.1.1 
Investigator Reporting Responsibilities to the Independent Ethics Committee 
and Other Agencies 
The investigator must promptly report to the IRB/IEC or independent ethics committees (IEC) 
all changes in the research activity and all unanticipated problems involving risk to human 
subjects or others.  This includes all SAEs that have occurred at the study site and all study-
related SAEs that have resulted in an expedited safety report to the FDA (serious, unexpected 
SAEs possibly or probably related to study drug).  The investigator must send all IRB/IEC 
documentation (including notifications and acknowledgements) to the sponsor or its designee.  
The investigator must not make any changes in the research without IRB/IEC approval, except 
where necessary to eliminate apparent immediate hazards to human subjects. 
8.3.2 
Reporting Requirements for Non-Serious Adverse Event  
Non-serious systemic and skin AEs experienced after the randomization phase of the study will 
be reported on the AE eCRF pages, which will be submitted to the sponsor or its designee.   
8.4 
Follow up of Adverse Events 
All SAEs must be followed up until resolution or, in the investigator’s opinion, a stable condition 
is reached, or until the subject is lost to follow up.  All follow up reports should be made by 
completing the SAE Report Form and by utilizing the same reporting procedures as the initial 
report. 
Based on the medical judgment of the investigator, all non-serious systemic and skin AEs will be 
followed until 14 days after the last visit.  All non-resolved, non-serious systemic and skin AEs 
beyond such date will be recorded as “ongoing” without further follow up.

EMERGENCY PROCEDURES 
9.1 
Emergency Contact 
In emergency situations, the investigator should contact the medical monitor by telephone at the 
numbers listed on the title page of the protocol.  If an SAE occurs, the PV Group is to be notified 
within 24 hours of awareness of the event by the investigator.  In particular, if the SAE is fatal or 
life-threatening, notification to the PV Group and the sponsor must be made immediately, 
irrespective of the extent of available AE information. 
9.2 
Unblinding Procedures 
If a medical emergency occurs and a decision regarding the subject’s clinical treatment requires 
knowledge of the treatment assignment, the study blind may be broken for the specific subject.  
Unless the medical emergency is deemed to be life-threatening, the medical monitor must first be 
consulted before unblinding.  The investigator would then access Medidata for unblinding. 
The date, time, and reason for unblinding must be documented in the source documents and on 
the applicable eCRF.  Investigators should note that the occurrence of a SAE should not 
routinely trigger immediate unblinding.  If the medical monitor was not notified prior to breaking 
the blind, the investigator must notify the medical monitor of any and all blinds broken within 24 
hours of each occurrence. 
9.3 
Emergency Treatment 
During and following a subject’s participation in the study, the investigator/institution should 
ensure that adequate medical care is provided to a subject for any systemic or skin AEs, 
including clinically significant laboratory values, related to the study.  The 
investigator/institution should inform a subject when medical care is needed for intercurrent 
illness(es) of which the investigator becomes aware.

study conduct from inception to completion in accordance with current GCPs.  This monitoring 
will be in the form of site visits and other communication and will include review of original 
source documents and eCRFs.  The Sponsor's monitor or representative will notify the Principal 
Investigator prior to conducting any investigational site visit.  The frequency of these visits will 
depend upon the progress of the study, and will include monitoring to assess facilities and 
equipment, recruiting, record-keeping, protocol adherence, data collection, AE reporting and 
other factors. 
10.2 
Audits and Inspections 
The clinical site will be subject to audit and inspection by the Sponsor or designee during or at 
the end of the study as appropriate. 
The Investigator will permit representatives of Zosano’s monitoring team or FDA/local health 
authority auditors to inspect facilities and records relevant to this study. 
10.3 
Institutional Review Board (IRB)/Independent Committee 
This protocol will be submitted to an appropriate central or local IRB/IEC and its written 
unconditional approval obtained and submitted to Zosano or its designee before arrival of the 
first subject. 
Zosano will supply relevant data for Investigators to submit to the IRB/IEC for the protocol’s 
review and approval.  Written verification of IRB/IEC unconditional approval of the protocol 
and the subject Informed Consent Form (ICF) will be transmitted to Zosano or its designee prior 
to granting access to the eCRF to study sites.  This approval must refer to the study by exact 
protocol title and number, identify documents reviewed and state the date of approval. 
The Investigator must promptly report to the IRB/IEC all changes in the research activity and all 
unanticipated problems involving risk to human subjects or others.  This includes all SAEs that 
have resulted in an expedited safety report to the FDA (serious, unexpected AEs possibly related 
to study drug).  Concurrently, the Investigator must send the study Sponsor documentation of 
such IRB/IEC notification and acknowledgement(s).  The Investigator must not make any 
changes in the research without IRB/IEC approval, except where necessary to eliminate apparent 
immediate hazards to human subjects. 
10.4

ETHICS 
12.1 
Ethics Review 
The IRB/IEC will review and approve the study protocol, the ICF and other relevant substantive 
data before the study is initiated.  A copy of the IRB/IEC approval letter for the protocol and the 
consent form/subject information sheet which specifically identifies the protocol name and the 
Zosano protocol number, must be sent to Zosano (or designee) prior to initiating the study.  
Subsequently, the Investigator is responsible for keeping the IRB/IEC advised of the progress of 
the study as deemed appropriate but, in any case, at least once a year during the course of the 
study and for keeping the IRB/IEC informed of any significant adverse reactions. 
12.1.1 
Ethical Conduct of the Study 
This study will be conducted in strict compliance with GCP, IRB/IEC and other relevant 
regulatory requirements.  The Investigator must ensure that each subject’s anonymity is 
maintained as described within this protocol.  On the eCRFs or other documents submitted to 
Zosano or its designee, subjects must be identified only by their initials and a subject number. 
Documents that are not for submission to Zosano and/or its designee (i.e., signed ICFs) should be 
kept in strict confidence by the Investigator, in compliance with Federal regulations and ICH 
GCP Guidelines.  The Investigator and institution must permit authorized representatives of 
Zosano or its designee, or the regulatory agency(s) and the IRB/IEC direct access to review the 
subject’s original medical records for verification of study-related procedures and data.  Direct 
access includes examining, analyzing, verifying, and reproducing any records and reports that 
are needed for the evaluation of the study.  The Investigator is obligated to inform the subject in 
the ICF that his/her study-related records will be reviewed by the above-named representatives. 
12.2 
Written Informed Consent 
Prior to study inception, each study participant (or legally authorized representative) will be 
required to read, sign and date an IRB/IEC-approved ICF that explains the nature, purpose, 
possible risks and benefits, and the duration of the study.  The study staff member who 
participated in the consent discussion with the participant must also sign and date the ICF.  Each 
participant will be given a copy of the ICF. 
The Investigator or designee shall give either the subject or the subject’s legally authorized 
representative adequate opportunity to read the ICF before it is signed and dated. 
The ICF must contain the subject’s dated signature or the signed and dated signature of the 
subject’s legally authorized representative (if applicable).  In addition, the dated signature of the 
person who conducted the informed consent discussion will also be documented on the consent 
form.  Each subject’s signed ICF must be kept on file by the Investigator and be available for 
possible inspection by regulatory authorities, and/or the study Sponsor or the regulatory 
compliance monitor, or the IRB/IEC.  All subjects will be informed of the nature of the program, 
its possible hazards, and their rights to withdraw at any time from the study without prejudice 
and without jeopardy to the subject’s future medical care at the center.  Documentation of the

informed consent and subject information discussion must appear in the subject’s medical 
record.  HIPAA authorization must also be provided (if applicable). 
A copy of the IRB/IEC-approved ICF must be sent to Zosano or designee. 
Each subject must agree to cooperate in all aspects of the study and must give informed written 
acknowledgment (ICF) to the Investigator for participation. 
Signed acknowledgments (ICF) must remain in the subject’s file and be available for verification 
by monitors at any time. 
12.3 
Disclosure of Data 
Individual subject medical information obtained because of this study is considered confidential, 
and disclosure to third parties other than those noted below is prohibited.  Subject confidentiality 
will be further assured by utilizing subject identification code numbers to correspond to 
treatment data in the computer files. 
However, such medical information may be given to the subject’s personal physician, or to other 
appropriate medical personnel responsible for the subject’s welfare. 
In addition, data generated as a result of this study are to be available for inspection upon request 
by FDA or local health authority auditors, the Sponsor’s monitors, or by the IRB/IEC.  
Therefore, absolute confidentiality cannot be guaranteed.

DATA HANDLING AND RECORDKEEPING 
13.1 
Inspection of Records 
All study-related documents and records are subject to inspection and audit by the Sponsor 
(or designee), and by the FDA, IRB/IEC or other relevant regulatory bodies.  The Statement of 
Investigator Form FDA 1572 and/or appropriate local health authority documents authorize the 
FDA or local health authority to inspect the data where the clinical trial was conducted. 
The Investigator/institution guarantees access to source documents by the study Sponsor or its 
designee, the FDA, other regulatory bodies and the IRB/IEC.  It is important that the Investigator 
and other study personnel are available during the monitoring visits, and that sufficient time is 
devoted to the process.  If the FDA or local health authority should schedule an inspection, 
Zosano’s Clinical Operations and Regulatory Affairs departments should be advised prior to the 
time this inspection is to occur. 
13.2 
Case Report Forms 
All clinical study data will be collected by the Investigator and staff, recorded on source 
documents and captured electronically in the proprietary subject e-source application, if 
appropriate.  Clinical data includes the following: demographics, history, physical examination, 
vital signs, clinical laboratory test results, safety ECGs, adverse event queries, adverse events, 
and concomitant medication queries. 
The data will be directly recorded on or transcribed to the study-specific eCRF.  The clinical 
investigator(s) will assume responsibility (by electronically signing the eCRF) for ensuring the 
completeness and accuracy of all clinical documents. 
Staff at each investigator site will perform data entry into the eCRF.  Study subjects will perform 
data entry in response to questions on the eDiary.  The Remote Data Capture (RDC) database 
that has been validated for this protocol will automatically generate data discrepancy notices 
within the system that will be identified to the clinic for resolution.  A list of all data quality 
checks utilized in the validation of the data will be provided in the Data Management Plan 
(DMP).  Query resolution will take place within the system and an audit trail will be attached to 
any data changes that will identify the user who is making the change and time that this change 
has occurred.  The eCRF will be monitored against source documents by the Sponsor’s 
representative and any subsequent data discrepancies identified will be captured within the 
CDMS. 
The eCRF development and database validation programs will be documented in the Data 
Management Plan (DMP) and will be tested before the database is released for data entry.  The 
validation of the data once entered into the eCRF/database will occur dynamically or nightly 
dependent upon the type of edit check required.  Any data discrepancies identified as a result of 
this validation routine will be documented.

INVESTIGATOR ASSESSMENTS – RATING FOR BRUISING, 
ERYTHEMA, EDEMA AND PHOTOGRAPHS 
The Bruising, Erythema, and Edema assessment will be performed by the investigator at the final 
visit 3 (or early discontinuation).  Any findings with an intensity rating of 1 (Mild intensity), 
2 (Moderate intensity), or 3 (Severe intensity) must be recorded as an adverse event in the eCRF 
and followed to resolution.  The investigator will use the definitions of AE Severity Ratings for 
Mild, Moderate, Severe, Life-Threatening (Section 8.2.1.3) to assess the Severity of the AE.
