SYNOPSIS 
TITLE:  A Multi-Center Randomized Study to Evaluate the Safety, Tolerability, and Efficacy  of 
Oral Encochleated Amphotericin B (CAMB) Compared With Oral Fluconazole in the Treatment 
of Moderate to Severe Vulvovaginal Candidiasis 
PROTOCOL NUMBER:  MB-70005 
INVESTIGATIONAL PRODUCT:  MAT2203 encochleated amphotericin B (CAMB) 
PHASE:  2 
INDICATION:  Moderate to severe vulvovaginal candidiasis 
OBJECTIVES: 
The primary objective of this study is to evaluate the safety of 200 mg (100 mg twice daily [BID]) 
and 400 mg (200 mg BID) doses of oral CAMB for 5 days compared with a single 150 mg dose 
of oral fluconazole in subjects with moderate to severe vulvovaginal candidiasis (VVC). 
The secondary efficacy objectives of this study are the following: 
 Assess the clinical cure rate of oral CAMB compared with oral fluconazole at the Test-of-Cure 
(TOC) Visit (Day 12); 
 Assess the mycology eradication rate for oral CAMB compared with oral fluconazole at the 
TOC Visit (Day 12); and  
 Assess the responder outcome by treatment group, separately, at the TOC Visit (Day 12). 
The tertiary objective of this study is to assess optional pharmacokinetics (PK) (ie, area under the 
concentration-time curve [AUC], clearance [CL], maximum plasma concentration [Cmax], 
terminal elimination half-life [t½], and time to maximum plasma concentration [Tmax]) of CAMB 
after 5 days of oral administration.   
POPULATION: 
The population for this study will be women age 18 to 65 years, inclusive, with a clinical diagnosis 
of moderate to severe VVC.   
STUDY DESIGN AND DURATION: 
This is a proof-of-concept, multi-center, randomized study to evaluate the safety, tolerability, and 
efficacy of 200 mg (100 mg BID) CAMB and 400 mg (200 mg BID) CAMB compared with a 
single 150 mg dose of fluconazole in the treatment of moderate to severe VVC. 
Approximately 100 women with moderate to severe VVC will be randomized in a 1:1:1 ratio to 
1 of 3 treatment groups (200 mg CAMB, 400 mg CAMB, or fluconazole). Randomization will be 
stratified by a signs and symptoms composite score of up to 12 (moderate) and 13 (severe).

Scoring of Symptoms and Signs of Vulvovaginal Candidiasis 
Vulvovaginal candidiasis signs and symptoms will be evaluated at screening and Days 1, 5, and 
12. Signs of VVC will be defined as the presence of erythema, edema, or excoriation. Symptoms 
of VVC will be defined as itching, burning, or irritation. 
Each vulvovaginal sign and symptom will be objectively scored based on severity as follows: 
0 = none (complete absence of any signs or symptoms), 
1 = mild (slight), 
2 = moderate (definitely present), or   
3 = severe (marked, intense). 
Dosing Schedule 
For subjects randomized to 200 mg CAMB and 400 mg CAMB, the preferred dosing regimen on 
Days 1 through 4 is 100 mg BID and 200 mg BID, respectively, with morning and evening meals. 
On Day 1, subjects will be administered the first dose according to their treatment assignment with 
a non-standardized meal or snack in the clinic.  
On Day 1, subjects randomized to 200 mg CAMB who enroll in the afternoon can take both 
100 mg doses as a single 200 mg dose or as 2 separate doses with a non-standardized meal or 
snack (once at enrollment and once in the evening); subjects randomized to 400 mg CAMB who 
enroll in the afternoon can take both 200 mg doses as a single 400 mg dose or as 2 separate doses 
with a non-standardized meal or snack (once at enrollment and once in the evening). 
On Day 5, subjects randomized to 200 mg CAMB and 400 mg CAMB will be administered a 
single dose of 200 mg and 400 mg, respectively, in the clinic with a non-standardized meal or 
snack.  
Other combinations of CAMB dosing are allowed throughout the study such that subjects 
randomized to 200 mg CAMB complete a course of ten 100 mg doses by Day 5 and subjects 
randomized to 400 mg CAMB complete ten 200 mg doses by Day 5. Subjects will be instructed 
to record their dosing in a patient diary. 
Subjects randomized to fluconazole will take a single 150 mg tablet on Day 1 without respect to 
food.  
Visit Schedule  
Participation in this study will consist of a screening period (up to 48 hours prior to Day 1); a 
5-day treatment period (5 days with 200 mg or 400 mg CAMB or 1 day with fluconazole); a 
mandatory pre-dose PK assessment on Day 5 for determination of trough plasma concentrations 
of CAMB; an optional serial PK assessment for subjects who agree to participate; a TOC/Early 
Withdrawal Visit on Day 12 (2 days), and a follow-up phone call between Days 21 to 30. For 
eligible subjects, screening and Day 1 can occur on the same day. Therefore, subjects who do not 
participate in the optional serial PK assessment will complete a total of 3 to 4 clinic visits, and 
subjects who do participate will complete a total of 4 to 5 clinic visits.  
At screening, subjects must provide written informed consent prior to any study procedures being 
performed. Papanicolaou (Pap) smear/tests will be performed for subjects (>21 years of age) who 
do not have a negative test for intraepithelial lesion or malignancy or atypical squamous cells of

undetermined significance in the past 36 months; in circumstances where the results of the Pap 
smear are pending at the time of randomization, eligible subjects may be randomized. Specimens 
will be collected for local testing to rule out Trichomonas vaginalis, Chlamydia trachomatis, and 
Neisseria gonorrhoeae. Subjects may be enrolled pending test results. Subjects who are later 
confirmed to be positive for C. trachomatis, N. gonorrhoeae, or T. vaginalis will not be required 
to stop treatment and should be encouraged to complete all remaining study visits. Subjects will 
undergo a physical examination and speculum examination of the vagina. Candida infections will 
be identified locally prior to randomization by a positive potassium hydroxide (KOH) wet mount 
test from a vaginal smear revealing filamentous hyphae/pseudohyphae and/or budding yeast cells 
OR a vaginal culture identifying a Candida infection no more than 1 week prior to randomization; 
subsequently, Candida infections will be confirmed by vaginal culture at the central laboratory. 
Speciation and susceptibility testing will be performed on all positive fungal cultures. At the 
discretion of the Sponsor, sites may be instructed to send an additional specimen to the local 
laboratory for culture at baseline. Signs and symptoms of infection will also be assessed, including 
itching, burning, irritation, erythema, edema, and/or excoriation of the vagina and/or the vulva.  
Safety assessments will include clinical laboratory assessments (including serum chemistry, 
hematology, and urinalysis), vital signs, body weight, electrocardiograms (ECGs), both complete 
and symptom-based physical examinations, prior and concomitant medication reporting, and 
adverse event reporting. Serum or urine pregnancy testing will be performed at screening and 
again at Day 1 if a subject’s screening period exceeds 24 hours. Coagulation assessments and 
height will be performed at screening only.  
On Day 1, subjects who meet all of the inclusion criteria and none of the exclusion criteria will be 
randomized and begin dosing with 200 CAMB, 400 CAMB, or fluconazole. Before leaving the 
study facility on Day 1, subjects will be advised to contact the Investigator to be re-assessed at an 
office visit if symptoms do not improve within 2 to 3 days. Subjects will also be advised to contact 
the Investigator if other events occur that cause concern.   
On Days 5 and 12, subjects will undergo a speculum examination of the vagina. Vaginal cultures 
will be sent to the central laboratory. Candida infections will be identified from vaginal cultures 
revealing filamentous hyphae/pseudohyphae and/or budding yeast cells identifying a Candida 
infection. Speciation and susceptibility testing will be repeated on all positive fungal cultures. 
Signs and symptoms of infection will also be assessed, including erythema, edema, excoriation, 
itching, burning, or irritation of the vagina and/or the vulva. 
On Day 5 (1 day for subjects not participating in the optional serial PK assessment), mandatory 
pre-dose PK blood samples will be collected from all subjects for determination of trough plasma 
concentrations of CAMB.  
The optional serial PK assessment will include approximately 24 subjects randomized to 200 mg 
or 400 mg CAMB, with approximately 12 subjects in each group. For subjects who consent to 
participate in the optional serial PK assessment, additional blood samples will be collected on 
Day 5 at 1, 2, 3, 4, 8, and 12 hours, and 24 hours post-dose. In circumstances where the 12-hour 
PK assessment is not feasible, it will not be required. On Day 5, subjects randomized to 200 mg 
CAMB and 400 mg CAMB will be administered a single dose of 200 mg and 400 mg, 
respectively, in the clinic with a non-standardized meal or snack regardless of participation in the 
optional serial PK assessment.

ANALYSIS POPULATIONS: 
The Intent-to-Treat Population (ITT) will include all subjects who were randomized. 
The Modified Intent-to-Treat (mITT) Population will include all randomized subjects who have a 
Candida species isolated on culture of vaginal specimen at baseline based on the central laboratory 
results.  
The Safety Population will include all ITT subjects who received at least 1 dose of study drug.  
The PK Population will include the subjects in the ITT Population with at least 1 PK sample. 
The Per-Protocol Population will include all of the mITT subjects who meet the following criteria: 
 No key inclusion/exclusion violations; 
 Received the complete course of study drug; 
 No major protocol violations that would affect the treatment evaluation; and  
 Has not received another systemic or topical antifungal drug that has documented activity 
against the causative organism before the TOC assessment, unless the subject has a therapeutic 
response of failure at a previous assessment visit. 
EFFICACY VARIABLES:  
The efficacy endpoints for this study will be performed on the mITT Population and Per-Protocol 
Population and will include the following: 
1. The proportion of subjects with clinical cure at the TOC Visit (Day 12); 
2. The proportion of subjects with mycological eradication at the TOC Visit (Day 12); and  
3. The proportion of subjects with overall success at the TOC Visit (Day 12). 
For the definition of clinical cure, mycological eradication, and overall success, see below. 
Assessment of Clinical Outcome 
Clinical outcomes will be assessed at the TOC Visit (Day 12) according to the following 
definitions: 
 Clinical cure – resolution of the VVC signs and symptoms that were present at baseline 
without further antifungal treatment. Specifically, any sign or symptom with a score of 1 or 2 
at entry should be absent (score = 0) by the TOC Visit. Any sign or symptom with a score 
of 3 (severe) at entry should have a score of 0 or 1 by the TOC Visit. If a new sign or symptom 
is observed at the TOC Visit that was not present at entry, the Investigator should state whether 
the new sign or symptom is related to VVC or not (ie, if related, the subject would be 
considered a failure; if not related, the subject may be considered a cure); 
 Clinical failure – incomplete resolution of signs and symptoms of VVC that were present at 
baseline or new signs and symptoms have developed and require the initiation of non-study 
antifungal drugs; and  
 Clinical indeterminate – insufficient data are available to determine if the subject is a cure or 
failure.

Assessment of Mycological Outcome 
Mycological outcomes will be assessed at Day 12 (2 days) (TOC Visit) according to the 
following definitions:  
 Mycological eradication – a vaginal swab culture negative for growth of baseline Candida 
species; 
 Mycological persistence – a vaginal swab culture positive for growth of baseline Candida 
species; and  
 Mycological indeterminate – no vaginal swab culture is available, or the culture cannot be 
interpreted for any reason, or the culture is considered contaminated. 
Assessment of Overall Response 
Overall response will be assessed at Day 12 (2 days) (TOC Visit) according to the following 
definitions:  
 Overall success – achievement of both a clinical cure AND microbiologic eradication;  
 Overall failure – clinical failure OR microbiological persistence; and  
 Overall indeterminate – insufficient data are available to determine if the subject is an overall 
success or failure. 
The assessment of overall response at the TOC Visit is summarized below.

PHARMACOKINETIC PARAMETERS: 
The PK parameters will include the following:  
 AUC: area under the concentration-time curve,  
 CL: clearance,  
 Cmax: maximum plasma concentration,  
 Ctrough: concentration of pre-dose CAMB, 
 t½: terminal elimination half-life, and  
 Tmax: time to maximum plasma concentration. 
STATISTICAL ANALYSES: 
Summary statistics will be presented by treatment group. For continuous variables, the number of 
observations (n), mean, standard deviation, median, minimum, and maximum will be provided. 
For categorical variables, the frequency and percentage in each category will be displayed. 
Efficacy analyses will be performed on the mITT and Per-Protocol Populations. The percentage 
of subjects with clinical cure, mycological eradication, and overall success will be summarized 
descriptively by treatment group. Clinical outcome, mycological outcome, and overall response 
will also be tabulated by treatment group. 
Safety analyses will be performed on all subjects in the Safety Population. Analyses will be based 
on adverse events, vital signs, clinical laboratory assessments, physical examination findings, and 
ECGs. Safety analyses in general will be descriptive and will be presented in tabular format with 
the appropriate summary statistics.  
The proportion subjects with hepatotoxicity, nephrotoxicity, and hypokalemia will be summarized 
by treatment group  
Descriptive statistics will be provided for PK concentration data and PK parameters. All PK 
analyses will be performed using the PK Population. 
SAMPLE SIZE DETERMINATION: 
Approximately 75 subjects are planned for the mITT population. Assuming 75% of randomized 
subjects will be evaluable for the mITT Population, a total of approximately 100 subjects will be 
randomized. The sample size was determined empirically rather than with a specific statistical 
rationale and is considered sufficient to achieve the study objectives. No formal sample size 
calculations were made. 
SITES:  Approximately 20 sites in the United States.
