Study Phase: 3 
Study Design: This is a multicenter, open-label, non-comparator, single-arm study to evaluate 
the efficacy, safety, tolerability and PK (for a subset of subjects) of SCY-078 in male and female 
subjects ≥18 years of age with a documented Candida auris infection.   
Study Population: Subjects must have a documented candidiasis, including candidemia, caused 
by Candida auris to be considered for enrollment. Subjects are also eligible if they are receiving 
intravenous (IV) antifungal therapy for their C. auris infection and, in the judgment of the 
investigator, continued IV antifungal therapy is not feasible or desirable due to clinical or 
logistical circumstances. Additionally, subjects must be able to tolerate medication orally or 
through a nasogastric (NG) tube or percutaneous endoscopic gastrostomy (PEG) tube to be able 
to participate in the study. Subjects must meet all study criteria to be eligible for inclusion. 
Inclusion of each subject in the study must be approved by the Sponsor prior to enrollment. 
The study will be conducted at approximately 10 sites globally, and is planned to enroll and treat 
approximately 30 subjects.  
Study Treatments: Eligible subjects will receive an initial oral loading dose of 750 mg of SCY-
078 (3 tablets of 250 mg) twice a day (BID) during the first 2 days of treatment and then 
subsequent oral doses of 750 mg once a day (QD) for up to 90 days. 
Study Visits: The study will consist of a combined Screening and Treatment Day 1 (Baseline) 
visit to determine subject eligibility and begin study treatment; a Treatment Day 2 visit for PK 
sampling (only for subjects who participate in the PK portion of the study); 2 additional 
scheduled treatment visits (Treatment Days 3 to 5 and Treatment Days 7 to 10) and treatment 
visits every 14 days thereafter (for up to a total of 90 days) to continue study treatment and 
perform clinical, mycological, imaging, serological and safety assessments, and to collect PK 
samples (only for subjects who participate in the PK portion of the study); an EoT visit to assess 
primary and exploratory efficacy outcomes; 1 follow-up (FU) visit 6 weeks after EoT (Week 6 
Follow-up) to assess recurrence (secondary efficacy endpoint) and safety; and 2 survival 
visits/contacts to determine survival status (alive or deceased). 
Efficacy: Efficacy will be assessed primarily in terms of global success (defined as a complete 
or partial global [clinical and mycological] response) at EoT as determined by the DMC. 
Secondary efficacy assessments will include recurrence (after EoT) and survival. Recurrence 
will be assessed by measuring recurrence of the baseline fungal infection 42 days after EoT 
(Week 6 FU). Survival will be determined on Day 42 and Day 84 (42 and 84 days after the 
Screening/Treatment Day 1 visit [first dose of study drug]).  This can be an in-person visit or a 
phone contact, and will document subject status only (alive or deceased). If subject is deceased, 
the relationship to the fungal infection will be recorded. 
Complete global response, partial global response, stable disease and progressive disease at EoT 
as determined by the DMC will be assessed as exploratory efficacy endpoints.  Global success, 
clinical success and mycological success at EoT as determined by the investigator will also be 
assessed as exploratory efficacy endpoints.

The following study procedures will be performed to assess treatment outcome: clinical signs 
and symptoms of candidiasis; radiological assessments including esophagoscopy and other 
imaging scans, as applicable (e.g., X-ray, ultrasound, CT and MRI); mycological testing (fungal 
cultures); and serological testing (ß-(1,3)-D glucan). 
Pharmacokinetics: PK analyses will be performed for subjects who give their consent to 
participate in the PK portion of the study (the PK Subset). Blood samples will be collected on 
Treatment Day 2 (one sample collected anytime post dosing), Treatment Days 3 to 5 (one sample 
collected predose on any of these days) and Treatment Days 7 to 10 (one sample collected 
predose on any of these days). 
Safety: Subjects will be evaluated for safety throughout the study, including parameters such as 
physical exam, vital signs, 12-lead ECGs, safety laboratory tests (hematology, blood chemistry 
and urinalysis), AEs, treatment discontinuations and concomitant medications. A final safety 
assessment will be conducted at the Week 6 Follow-up visit (6 weeks after the EoT). 
Analyses: Results from the study will be analyzed against historical SoC-treated subjects, who 
will be selected from literature reviews and other data resources, and be based on the 2015 
Infectious Diseases Society of America guidelines for the management of candidiasis. 
Target Population: Subjects ≥18 years of age with documented candidiasis, including 
candidemia, caused by Candida auris. 
KEY Inclusion Criteria:  
Subject must fulfill the following KEY criteria to be eligible for study admission: 
1. 
Subject is a male or female adult ≥ 18 years of age on the day the study informed consent 
form (ICF) is signed. 
2. 
Subject has a documented candidiasis, including candidemia, caused by Candida auris. The 
subject is also eligible if he/she is receiving IV antifungal therapy for their C. auris infection 
and, in the judgment of the investigator, long-term IV antifungal therapy is not feasible or 
desirable due to clinical or logistical circumstances. 
A documented candidiasis, including candidemia, caused by Candida auris is defined as 
the recovery of Candida auris by culture of a sample obtained within the last 7 days.  
3.

>480 ms on the baseline ECG or other abnormalities deemed clinically significant by the 
investigator that would put the subject at unacceptable risk for participation in the study. 
Study Drugs: SCY-078 citrate drug product for oral administration will be supplied as a tablet 
containing 250 mg of SCY-078 active ingredient on a free-base basis. In addition to the active 
ingredient, the tablet formulation also contains silicified microcrystalline cellulose, 
crospovidone, mannitol, colloidal silicon dioxide, magnesium stearate (non-bovine) and 
butylated hydroxyanisole. 
SCY-078 tablets are to be stored at room temperature, between 15C and 30C.  
Randomized Treatment Groups: This is an open-label, single-arm study. There will be no 
randomization or stratification for this study. Eligible subjects must be approved by the sponsor 
for enrollment. 
Subjects will receive an initial oral loading dose of 750 mg of SCY-078 (3 tablets of 250 mg) 
twice a day (BID) during the first 2 days of treatment and then subsequent oral doses of 750 mg 
once a day (QD) for up to 90 days. 
Study Blinding:  Open-label study 
Pharmacokinetic Evaluations (PK Subset Only): PK testing will be conducted for subjects 
who give their consent to participate in the PK portion of the study (the PK Subset). Up to three 
(3) blood samples will be collected at the following visits and sampling windows: Treatment 
Day 2 (one sample collected anytime post dosing), Treatment Days 3 to 5 (one sample collected 
predose on any of these days) and Treatment Days 7 to 10 (one sample collected predose on any 
of these days). 
The sparse samples collected in this study will be analyzed using Population PK (Pop PK) 
analysis methods to estimate PK parameters (Cmax, AUC, clearance/fraction absorbed [CL/F]) as 
applicable. 
Efficacy Evaluations: Efficacy will be assessed primarily in terms of global success (defined as 
a complete or partial global [clinical and mycological] response) at EoT as determined by the 
DMC. Complete global response, partial global response, stable disease and progressive disease 
at EoT as determined by the DMC will be assessed as exploratory endpoints.  Global success, 
clinical success and mycological success at EoT as determined by the investigator will also be 
assessed as exploratory endpoints. 
The following treatment outcome definitions will be used for the assessment of efficacy: 
Global Outcome 
Global outcome will be scored as global success (complete global response or partial global 
response) or global failure (stable disease or progressive disease) 
Global success: Global success is defined as a complete global response or a partial global 
response 
 
Complete global response is defined as a complete clinical response (the resolution of all 
clinical signs and symptoms and/or radiological abnormalities from baseline attributable to 
the Candida auris infection) and a mycological response (mycological clearance (direct 
and/or negative cultures [when obtainable] and/or normal serological results [when 
appropriate]) 
 
Partial global response is defined as a partial clinical response (major improvement of all 
clinical signs and symptoms and/or radiological abnormalities from baseline attributable to 
the Candida auris infection) and a mycological response (mycological clearance (direct 
and/or negative cultures [when obtainable] and/or normal serological results [when 
appropriate]) 
Global failure: Global failure is defined as either stable disease and/or progressive disease

 
Stable disease is defined as minor or no clinical improvement but without deterioration 
and/or unchanged serological response. 
 
Progressive disease is defined as clinical deterioration necessitating alternative antifungal 
therapy or resulting in death, and/or worsened serological response, and/or persistence of 
fungal infection on the basis of culture, microscopic evaluation, or histopathological testing. 
Clinical Outcome 
Clinical success: clinical success is defined as a complete clinical response (the resolution of all 
clinical signs and symptoms and/or radiological abnormalities from baseline attributable to the 
Candida auris infection) or a partial clinical response (major improvement of all clinical signs 
and symptoms and/or radiological abnormalities from baseline attributable to the Candida auris 
infection).  
Mycological Outcome 
Mycological success: mycological success is defined as a mycological response (mycological 
clearance (direct and/or negative cultures [when obtainable] and/or normal serological results 
[when appropriate]). 
Efficacy assessments will also include recurrence (after EoT) and survival. Recurrence will be 
assessed by measuring recurrence of the baseline fungal infection 42 days after EoT (Week 6 
FU). Survival will be determined on Day 42 and Day 84 (42 and 84 days after 
Screening/Treatment Day 1 [first dose of study drug]).  
Recurrence: recurrence is defined as global success at EoT but re-emergence of the baseline 
Candida auris infection during the post treatment follow-up.  Re-emergence of the Candida 
auris infection is required to be with the same species and involving the same site that was 
initially identified at Screening/Treatment Day 1.  
Safety Evaluations:  
Subjects will be evaluated for safety and tolerability throughout the study, including parameters 
such as physical exam, vital signs, 12-lead ECGs, safety laboratory tests (hematology, blood 
chemistry and urinalysis), concomitant medications, AEs and treatment discontinuations. 
Statistical Analyses:  
Descriptive statistics (i.e., number of subjects, mean, standard deviation, median, minimum, 
maximum) will be presented for all continuous variables; number and percentage of subjects will 
be presented for categorical variables. For parameters measured over time, observed data and 
changes from baseline will be described for each time point. 
All analyses of the study results for SCY-078 will be descriptive. Unless otherwise stated, data 
will be analyzed as is with no imputation. 
Sample Size Determination: This is an exploratory study and no formal sample size calculation 
was performed. A total of 30 subjects are estimated to be adequate for an assessment of the safety 
and tolerability of SCY-078 in subjects with candidiasis, including candidemia, caused by C. 
auris.  
Analysis Populations: 
 
Intent-to-Treat (ITT) Population: The ITT population will include all subjects who are 
enrolled in the study.  
 
Per-Protocol (PP) Population: The PP population will include all ITT subjects who receive 
at least 10 total days of antifungal therapy (SCY-078), who have an EoT assessment and 
who have no major protocol violations that would impact the assessment of efficacy.  
 
Safety Population: The safety population will include all subjects who receive at least one 
dose of study medication and have at least one safety assessment post baseline.

Background Information and Scientific Rationale 
9.1 
Background Information 
Candida is among the most common causes of healthcare-associated bloodstream infections in the 
United States (US), with an estimate of 46,000 healthcare-associated Candida infections occurring 
among hospitalized patients in the US each year. The CDC surveillance data have reported that 
approximately 7% of all Candida bloodstream isolates tested are resistant to fluconazole and some 
Candida strains are increasingly resistant to first-line and second-line antifungal treatment agents, 
including azoles and echinocandins.1 Centers specialized in the treatment of immune-
compromised patients report increased frequency of non-albicans species of Candida with higher 
incidence of resistance. For example, in a survey conducted in the MD Anderson Cancer Center, 
Houston, Texas, US (2005–2013), out of 146 isolates of C. glabrata evaluated, 30 (20.5%) were 
resistant to fluconazole; 15 (10.3%), to caspofungin; and 10 (6.8%), to multiple drugs.2 Roughly, 
30% of patients with drug-resistant Candida bloodstream infections (candidemia) due to drug-
resistant Candida die during their hospitalization. 
Candida auris is an emerging fungus that presents a serious global health threat. Healthcare 
facilities in several countries have reported that C. auris has caused severe illness in hospitalized 
patients. Some strains of Candida auris are resistant to all three major classes of antifungal drugs. 
This type of multidrug resistance has not been seen before in other species of Candida. Also of 
concern, C. auris can persist on surfaces in healthcare environments and spread between patients 
in healthcare facilities, unlike most other Candida species.3  
SCY-078 is a member of a new class of antifungal agents and is an orally active, semi-synthetic, 
triterpene derivative of the natural product enfumafungin. SCY-078 is a structurally distinct class 
of glucan synthase inhibitor that inhibits the synthesis of the fungal cell wall polymer β-(1,3)-D-
glucan. Time kill studies have demonstrated that SCY-078 has fungicidal in vitro activity against 
Candida spp. isolates similar to that observed with the echinocandins. 
While three classes of antifungal agents (azoles, echinocandins and polyenes) are currently 
available to treat Candida  infections, the emergence of resistance to azoles and echinocandins as 
well as the toxicity associated with polyenes signals the need for new agents that are well tolerated 
and retain activity against resistant strains. SCY-078 represents the first compound of the triterpene 
class of β-(1,3)-D-glucan synthesis inhibitors in development for the treatment of fungal 
infections. It is structurally distinct and retains activity in vitro against both azole-resistant and, 
importantly, the majority of clinical isolates containing FKS gene mutations, which confer 
echinocandin resistance. Unlike echinocandins, SCY-078 is orally bioavailable, with in vitro and 
in vivo activity against Candida and Aspergillus species and, as such, it would represent the first 
oral non-azole treatment alternative for these infections.  SCY-078 is being developed as the first 
oral and intravenous (IV) glucan synthase inhibitor for the treatment and prevention of fungal

infections caused by Candida and Aspergillus species with the potential to provide the therapeutic 
advantages of both an IV and oral formulation. 
 
Activity against Candida spp. 
SCY-078 has been evaluated against >1600 Candida isolates, including all clinically relevant 
species, more than 400 C. glabrata isolates and >100 C. auris isolates.4,5 These in vitro studies 
have demonstrated the broad range of anti-Candida spectrum of activity of SCY-078. 
Additionally, SCY-078 demonstrated in vitro activity against pre-formed biofilms,6 which is a 
relevant feature when addressing catheter-related Candida infections. Studies conducted with 
azole- and echinocandin-resistant strains have shown that SCY-078 retains activity (i.e., no 
significant change in minimum inhibitory concentration MIC] when compared to wild type) 
against >90% of azole-resistant strains and >70% of Candida strains with FKS mutations 
commonly associated with echinocandin resistance.7 Interestingly, although SCY-078 and the 
echinocandins share a similar mechanism of action (β-[1,3]-D-glucan synthesis inhibition), their 
clearly different molecular structure provides them with some differentiating characteristics in 
terms of microbiological activity.  
SCY-078 was evaluated in vitro against >170 clinical isolates of echinocandin-resistant strains of 
Candida spp., >95% of which contained mutations in the FKS gene. Overall, SCY-078 was active 
against the majority of the echinocandin-resistant strains tested. Significantly, SCY-078 was active 
against approximately 70% of the isolates containing the most commonly reported FKS mutation 
associated with echinocandin resistance in C. glabrata (S663P in FKS2 and S645P in FKS1).7 
Selection of SCY-078 resistance in vitro occurs at a low frequency. A deletion at position F659 in 
FKS2 of C. glabrata was the predominant mutation observed in these studies; notably, SCY-078 
did not select for mutations at positions S663 or S645.8 These results suggest that SCY-078 inhibits 
glucan synthase in a manner different from that of echinocandins.  
SCY-078 has also demonstrated a potent activity against life-threatening C. auris strains. SCY-
078 has been evaluated against >100 clinical C. auris strains, approximately 20 of which were 
drug resistant.5 SCY-078 demonstrated efficacy against both wild type (WT) and drug-resistant 
isolates in these studies at concentrations indicative of potential clinically relevant effect. Candida 
auris is an emerging, multi-resistant yeast that can cause invasive infections and is associated with 
high mortality. It is typically resistant to fluconazole and exhibits markedly variable susceptibility 
to other azoles, amphotericin B and echinocandins.4,9,10 It is currently recognized to be the first 
exogenous candida infection.  C. auris has been recently highlighted as a clinical alert by the 
Centers for Disease Control and Prevention (CDC) because of the global emergence of this fungal 
infection with limited therapeutic options and high mortality.

Antifungal activity  
The spectrum and potency of activity of SCY-078 has been evaluated by numerous independent 
laboratories against an extensive panel of clinically relevant yeast and mold isolates using the 
Clinical and Laboratory Standards Institute (M27-A3 guidelines)4,11 and European Committee on 
Antimicrobial Susceptibility Testing (EUCAST) methods. Overall, the epidemiological studies 
have demonstrated that SCY-078 has potent, broad-spectrum activity against the majority of the 
clinical isolates tested. These studies have laid the foundation in support of the use of SCY-078 
for the treatment of invasive fungal infections.  
 
Murine models of invasive fungal infections  
The antifungal efficacy of SCY-078 has been evaluated in several murine models of disseminated 
candidiasis and aspergillosis. In a disseminated C. albicans model, SCY-078 was more active than 
fluconazole at all doses. Murine models of SCY-078 in disseminated candidiasis caused by C. 
glabrata and C. tropicalis indicated activity across multiple Candida species. The SCY-078 area 
under the curve (AUC) in plasma necessary to achieve target efficacy in these models was 
estimated to be 15.4 ± 2.2 μM•hr. Also, in an invasive murine model for C. auris, dose-related 
improvements in survival and reductions in kidney fungal burden were observed. 
In a murine model of disseminated A. fumigatus infection that evaluated both WT and azole-
resistant strains, treatment with SCY-078 resulted in improved survival and significant decreases 
in kidney fungal burden at all doses. The exposure needed to achieve efficacy is in line with 
efficacious exposures reported in the invasive candidiasis models. 
The data available from all of the in vitro and in vivo studies conducted to date provide significant 
support for the use of SCY-078 in the treatment of invasive fungal infections.  
 
Nonclinical experience  
Toxicology studies in rats and dogs have been conducted with the oral formulation of SCY-078 
administered for up to 90 days. The results from these studies indicate that SCY-078 is well 
tolerated and support the doses and treatment duration intended in this study.  
The in vitro studies indicated that SCY-078 metabolism was predominantly oxidative, with 
cytochrome P450 (CYP) 3A being the primary enzyme involved in its oxidative metabolism. 
Strong inhibitors of CYP3A would be expected to increase plasma levels of SCY-078; therefore, 
the concurrent administration of SCY-078 with such inhibitors should be avoided.

Clinical experience  
To date, over 300 subjects and patients have received either oral or IV formulations of SCY-078 
in Phase 1 and Phase 2 studies.  
SCY-078 was generally well tolerated following single oral doses of up to 1600 mg and multiple 
oral doses of up to 800 mg/day for 28 consecutive days in Phase 1 studies. Reported adverse events 
(AEs) after oral administration have been generally transient and primarily mild to moderate in 
intensity. The most frequently reported AEs have been mild gastrointestinal events (nausea, 
vomiting, diarrhea and abdominal pain).  
A Phase 2 study of oral SCY-078 as step-down therapy from IV echinocandin in patients with 
invasive candidiasis has been completed. This was a multicenter, randomized, open-label study in 
which, following three to ten days of IV echinocandin therapy, 21 patients received either SCY-
078 500 mg once daily (QD) with a 1000 mg loading dose (6 patients), SCY-078 750 mg QD with 
a 1250 mg loading dose (7 patients) or standard of care (SOC) treatment (8 patients with either 
oral fluconazole 400 mg QD with an 800 mg loading dose or IV micafungin 100 mg QD for up to 
28 days). SCY-078 was well tolerated in this study, with an AE profile typical of this population 
and comparable to the SOC. The results from this study also indicated that the higher dose of SCY-
078 tested (750 mg QD) is predicted to achieve the target exposure at steady state in the majority 
of patients.  
A Phase 2 proof-of-concept study of oral SCY-078 in patients with vulvovaginal candidiasis 
(VVC) has also been completed. In this multicenter, randomized, active-controlled, evaluator-
blinded study of oral SCY-078 compared to oral fluconazole in adult female patients with VVC, 
96 patients with an acute, moderate to severe, symptomatic episode of VVC were randomized in 
a 1:1:1 ratio to receive either oral SCY-078 750 mg with a 1250 mg loading dose for three days, 
oral SCY-078 750 mg with a 1250 mg loading dose for five days or a single dose of oral 
fluconazole. SCY-078 was well tolerated, with the most common AEs being mild gastrointestinal 
events. The high clinical cure rates observed in this study are supportive of the clinically relevant 
antifungal activity of SCY-078 in this form of Candida infection.  
Several drug-drug interaction studies have been conducted. Ketoconazole (a strong inhibitor of 
CYP3A) induces a significant (5-fold) increase in SCY-078 exposure, while diltiazem (a moderate 
inhibitor of CYP3A) induces a mild to moderate (<3 fold) increase in SCY-078 exposure. SCY-
078 did not have any effect on rosiglitazone (a CYP2C8 substrate) exposure, had only a mild effect 
(less than a 0.5-fold increase) on the AUC of tacrolimus (a CYP3A and P-gp substrate) and had 
no effect on the maximum concentration (Cmax) of tacrolimus. 
SCY-078 has the potential to be an important addition to the anti-fungal treatment arsenal by 
providing potent activity against the full spectrum of Candida species, including difficult-to-treat 
organisms, and by affording the added flexibility of both oral and IV formulations.

Rationale for the Study 
This study is being conducted to evaluate the efficacy, safety, tolerability and PK (for a subset of 
subjects) of SCY-078 in male and female subjects >18 years of age with a documented Candida 
auris infection.  
The primary efficacy endpoint of the study is global success, defined as either a complete or partial 
global (clinical and mycological) response. The primary endpoint will be determined at the end of 
treatment (EoT).12,13  Clinical response will be evaluated by the signs and symptoms of the 
infection and/or imaging scans, if applicable. Mycological response will be assessed by fungal 
culture and serological testing (β-(1,3)-D-glucan),14 if applicable. Recurrence will be assessed 42 
days after the EoT (Week 6 Follow-up) as a secondary efficacy endpoint. Recurrence is defined as 
global success at EoT but re-emergence of the baseline Candida infection (with the  same Candida 
species and involving the same site) during the post treatment follow-up.13

12.0 Study Design 
12.1 
Overall Description of the Study 
This is a multicenter, open-label, non-comparator, single-arm study to evaluate the efficacy, safety, 
tolerability and PK (for a subset of subjects) of SCY-078 in male and female subjects ≥18 years 
of age with a documented Candida auris infection.  
Subjects must have a documented candidiasis, including candidemia, caused by Candida auris to 
be considered for enrollment. Subjects are also eligible if they are receiving IV antifungal therapy 
for their C. auris infection and, in the judgment of the investigator, continued IV antifungal therapy 
is not feasible or desirable due to clinical or logistical circumstances. Additionally, subjects must 
be able to tolerate medication orally or through a nasogastric (NG) tube or percutaneous 
endoscopic gastrostomy (PEG) tube to be able to participate in the study.  
Subjects must meet all study criteria to be eligible for inclusion. Inclusion of each subject in the 
study must be approved by the Sponsor prior to enrollment. 
The study will be conducted at approximately 10 sites globally, and is planned to enroll and treat 
approximately 30 subjects.  
Eligible subjects will receive an initial oral loading dose of 750 mg of SCY-078 (3 tablets of 250 
mg) BID during the first 2 days of treatment and then subsequent oral doses of 750 mg QD for up 
to 90 days. 
The study will consist of a combined Screening and Treatment Day 1 (Baseline) visit to determine 
subject eligibility and begin study treatment; a Treatment Day 2 visit for PK sampling (only for 
subjects who participate in the PK portion of the study); 2 additional scheduled treatment visits 
(Treatment Days 3 to 5 and Treatment Days 7 to 10) and treatment visits every 14 days thereafter 
(for up to a total of 90 days) to continue study treatment and perform clinical, mycological, 
imaging, serological and safety assessments, and to collect PK samples (only for subjects who 
participate in the PK portion of the study); an EoT visit to assess primary and exploratory efficacy 
outcomes; 1 follow-up (FU) visit 6 weeks after EoT (Week 6 Follow-up) to assess recurrence 
(secondary efficacy endpoint) and safety; and 2 survival visits/contacts to determine survival status 
(alive or deceased). 
Efficacy will be assessed primarily in terms of global success (defined as a complete or partial 
global [clinical and mycological] response) at EoT as determined by the DMC. Secondary efficacy 
assessments will include recurrence (after EoT) and survival. Recurrence will be assessed by

document subject status only (alive or deceased). If subject is deceased, the relationship to the 
fungal infection will be recorded. 
Complete global response, partial global response, stable disease and progressive disease at EoT 
as determined by the DMC will be assessed as exploratory efficacy endpoints.  Global success, 
clinical success and mycological success at EoT as determined by the investigator will also be 
assessed as exploratory efficacy endpoints. 
The following study procedures will be performed to assess treatment outcome: clinical signs and 
symptoms of candidiasis; radiological assessments including esophagoscopy and other imaging 
scans, as applicable (e.g., X-ray, ultrasound, CT and MRI); mycological testing (fungal cultures); 
and serological testing (ß-(1,3)-D glucan). 
PK analyses will be performed for subjects who give their consent to participate in the PK portion 
of the study (the PK Subset). Blood samples will be collected on Treatment Day 2 (one sample 
collected anytime post dosing), Treatment Days 3 to 5 (one sample collected predose on any of 
these days) and Treatment Days 7 to 10 (one sample collected predose on any of these days).  
Subjects will be evaluated for safety throughout the study, including parameters such as physical 
exam, vital signs, 12-lead ECGs, safety laboratory tests (hematology, blood chemistry and 
urinalysis), AEs, treatment discontinuations and concomitant medications. A final safety 
assessment will be conducted at the Week 6 Follow-up visit (6 weeks after the EoT). 
Results from the study will be analyzed against historical SoC-treated subjects, who will be 
selected from literature reviews and other data resources, and be based on the 2015 Infectious 
Diseases Society of America guidelines for the management of candidiasis.15

13.0 Study Population 
13.1 
Inclusion Criteria 
Subjects must fulfill all of the following criteria to be eligible for study admission:  
1. Subject is a male or female adult ≥18 years of age on the day the study informed consent form 
(ICF) is signed. 
2. Subject has a documented candidiasis, including candidemia, caused by Candida auris. The 
subject is also eligible if he/she is receiving IV antifungal therapy for their C. auris infection 
and, in the judgment of the investigator, long-term IV antifungal therapy is not feasible or 
desirable due to clinical or logistical circumstances.  
A documented candidiasis, including candidemia, caused by Candida auris is defined as the 
recovery of Candida auris by culture of a sample obtained within the last 7 days.  
3. Subject is able to tolerate medication orally or through a nasogastric (NG) tube or 
percutaneous endoscopic gastrostomy (PEG) tube.   
4. Subject is not pregnant and is highly unlikely to become pregnant or to impregnate a partner 
since he/she meets at least one of the following criteria:  
a. 
Subject is a female subject who is not of reproductive potential and is eligible without 
requiring the use of contraception. A female subject who is not of reproductive potential 
is defined as one who: (1) has reached natural menopause (defined as 6 months of 
spontaneous amenorrhea with serum follicle-stimulating hormone levels in the 
postmenopausal range as determined by the local laboratory, or 12 months of spontaneous 
amenorrhea); (2) is 6 weeks´ post-surgical bilateral oophorectomy with or without 
hysterectomy; or (3) has undergone bilateral tubal ligation. Spontaneous amenorrhea does 
not include cases for which there is an underlying disease that causes amenorrhea (i.e., 
anorexia nervosa). 
b. Subject is a male subject who is not of reproductive potential and is eligible without 
requiring the use of contraception. A male subject who is not of reproductive potential is 
defined as one whom has undergone a successful vasectomy. A successful vasectomy is 
defined as (1) microscopic documentation of azoospermia, or (2) a vasectomy more than 
2 years ago with no resultant pregnancy despite sexual activity post vasectomy. 
c. Subject is a male or female subject who is of reproductive potential and agrees to remain 
abstinent or use (or have his/her partner use) 2 acceptable methods of contraception 
starting from the time of consent through 28 days after the completion of study therapy.

It is not yet known if the use of SCY-078 reduces the efficacy of hormonal contraception 
(including but not limited to oral, injectable, or implantable methods).  Therefore, 
hormonal contraception should not be used without a second study acceptable method of 
birth control.  
Note: Women of childbearing potential must have a negative serum pregnancy test (β-human 
chorionic gonadotropin [β-hCG]) prior to enrollment (performed by the site’s local 
laboratory). 
5. Subject and/or legal representative is/are able to understand and sign a written ICF, which 
must be obtained prior to treatment and any study-related procedures.

16.2 
Inclusion and Exclusion Criteria 
All inclusion and exclusion criteria will be reviewed at Screening/Treatment Day 1 (prior to study 
treatment) to ensure that the subject qualifies for the trial. 
16.3 
Subject Enrollment and Assignment of Subject Number 
At Screening/Treatment Day 1, all subjects who have signed an ICF will receive an 8-digit subject 
identification (ID) number (prior to study treatment) that will be composed of a 3-digit study 
number (305) and a 2-digit site number followed by a 3-digit sequentially assigned subject number 
starting at 001. Subject numbers will be sequentially assigned by the database upon entry by the 
site. For instance, if site 01 enters the first subject in the database, the subject ID will be 305-01-
001. The second subject entered in the database will get the subject number 002 as entered by any 
site, so that if site 02 enters the second subject, the subject ID will be 305-02-002. This number 
will be unique to each subject and will be used to identify the subject throughout the study.  
Subjects who are screen failures or who are not eligible for enrolment will be recorded as such in 
the subject screening log. The subject numbers assigned to eligible subjects will be recorded in the 
eCRF. Only one subject number will be assigned to each eligible subject.  
For subjects who signed an ICF (i.e., are assigned a subject number) but were NOT treated because 
they did not meet all of the inclusion/exclusion criteria, the Screening/Treatment Day 1  visit pages 
of the eCRF will be completed. The criteria that were not met for enrolment will be documented 
in the eCRF.  
All eligible subjects must be approved by the Sponsor for enrollment. 
16.4 
Medical History and Demographics 
During the Screening/Treatment Day 1 visit (prior to study treatment), a complete medical history 
for the prior year will be recorded for each subject. The medical history will include previous and 
current medical diagnoses, as well as major surgical procedures. Subject demographics such as 
age, sex, race and ethnicity will also be collected. 
16.5 
General Physical Examination  
A general physical exam will be done at Screening/Treatment Day 1 (prior to study treatment), at 
EoT and at the Week-6 Follow-up visit. The physical examination will include an abbreviated 
assessment of general appearance, skin, eyes, heart, chest and abdomen.

Vital Signs 
Vital signs, including blood pressure (systolic and diastolic), heart rate, respiratory rate and body 
temperature will be measured at Screening/Treatment Day 1 (prior to study treatment), at EoT and 
at unscheduled visits, if applicable. 
16.7 
Twelve-Lead Electrocardiogram  
A 12-lead ECG will be obtained and evaluated locally by a physician for the presence of 
abnormalities at Screening/Treatment Day 1 (prior to study treatment), at EoT and at unscheduled 
visits, if applicable. 
Heart rate, PR interval, QRS, QT and QTcF values will be recorded in the eCRF. Any clinically 
relevant abnormality will be recorded as AE accordingly and will be followed up to 
resolution/satisfaction. 
16.8 
Pregnancy Test  
A serum pregnancy test will be performed at Screening/Treatment Day 1 (prior to study treatment) 
and at EoT by the local laboratory for all female subjects of childbearing potential.  
16.9 
Targeted Physical Examination, Including Clinical Evaluation of Signs 
and Symptoms of Infection 
A targeted examination of the fungal infection site, including the signs and symptoms of the fungal 
disease, will be conducted at Screening/Treatment Day 1 (prior to study treatment), Treatment 
Days 3 to 5, Treatment Days 7 to 10, every 14 days thereafter up to EoT, at EoT, and at the Week 6 
Follow-up. 
The signs and symptoms of the fungal disease include, but are not limited to, the following: 
o Fever, defined as oral temperature ≥38.3°C (≥101°F) on one occasion or >37.8°C 
(>100°F) on two measurements at least 4 hours apart  
o Clinically significant hypothermia <36°C (<96.8°F) 
o Hypotension (systolic blood pressure <90 mmHg or a >30 mmHg decrease below 
normal baseline) 
o Tachycardia 
Subjects who are discharged from the hospital during SCY-078 therapy will record signs and 
symptoms daily on subject diaries and the signs and symptoms will also be assessed by the site 
staff at the study visits. The site will assess whether the signs and symptoms recorded on the subject 
diary are related to the C. auris infection.

16.10 Mycological Testing 
Blood cultures: Two sets of blood cultures will be collected at Screening/Treatment Day 1 (prior 
to study treatment) and repeated daily or every other day until blood cultures are negative for at 
least 48 hours (if it is only possible to obtain 1 set of blood cultures, a reason should be 
documented). Blood should be drawn peripherally [directly from a vein]; however, if this is not 
possible, blood may be drawn from  a central IV catheter. Follow-up cultures will be performed as 
clinically indicated. 
Non-blood cultures: A documented culture positive for C. auris of a sample obtained within the 
last 7 days must be available at Screening/Treatment Day 1 (prior to study treatment). Follow-up 
cultures from subjects who have non-blood Candida auris infections should be performed as 
clinically indicated. 
The study site’s local microbiology laboratory will perform identification and in vitro 
susceptibility testing as per their local standards. The investigator should ensure that all Candida 
auris isolates obtained from all cultures performed during the study period are sent to the central 
microbiology laboratory, as described in the laboratory manual.  
Further evaluation to identify the potential mechanism of resistance may be performed.  Isolates 
may be maintained in a repository for potential future use, for subjects that provide consent for 
future use. 
16.11 Imaging  
Imaging scans (e.g., X-ray, ultrasound, computed tomography, magnetic resonance imaging) 
should be performed for the assessment of infection in subjects with non-blood sites of Candida 
infection. The results of these studies should be documented on the eCRF. 
For subjects with fungal diseases where the assessment of outcome is based on imaging, imaging 
scans must be available at Screening/Treatment Day 1 (prior to study treatment) and performed at 
EoT. Additional  images should be obtained if clinically indicated. 
16.12 Serological Testing 
The following serological examinations will be performed at Screening/Treatment Day 1 (prior to 
study treatment) and at the recommended time points below:  
 Two ß-(1,3)-D-glucan consecutive tests every 72 hours until negative

16.14 Pharmacokinetic Sample Collection (PK Subset Only) 
PK testing will be conducted for subjects who give their consent to participate in the PK portion 
of the study (the PK Subset). Up to three (3) blood samples will be collected at the following visits 
and sampling windows: Treatment Day 2 (one sample collected anytime post dosing), Treatment 
Days 3 to 5 (one sample collected predose on any of these days) and Treatment Days 7 to 10 (one 
sample collected predose on any of these days).  
On PK sampling days, the investigator must record the dosing times and sample collection times 
on the eCRF and on the subject’s medical record.  
Procedures for collecting, storing, and shipping plasma samples for PK are described in the study 
PK Manual. The sparse samples collected in this study will be analyzed using Population PK (Pop 
PK) analysis methods to estimate PK parameters (Cmax, AUC, clearance/fraction absorbed [CL/F]) 
as applicable. 
Further analysis of possible metabolites may be performed. 
 
16.15 Efficacy Assessment  
Efficacy will be assessed primarily in terms of global success at EoT as determined by the DMC. 
Complete global response, partial global response, stable disease and progressive disease as 
determined by the DMC and global success, clinical success and mycological success as 
determined by the investigator will also be assessed at EoT.  
The following study procedures will be performed to assess treatment outcome:

 Clinical signs and symptoms of candidiasis (Section 16.9) 
 Radiological assessments including esophagoscopy and other imaging scans, as applicable 
(e.g., X-ray, ultrasound, CT and MRI) (Section 16.11). 
 Mycological testing (fungal cultures) (Section 16.10.) 
 Serological testing (ß-(1,3)-D glucan) (Section 16.12) 
Efficacy assessments will also include recurrence (after EoT) and survival. Recurrence will be 
assessed by measuring recurrence of the baseline fungal infection 42 days after EoT (Week 6 FU). 
Survival will be determined on Day 42 and Day 84 (42 and 84 days after Screening/Treatment Day 
1 [first dose of study drug]). This can be an in-person visit or a phone contact, and will document 
subject status only (alive or deceased). If subject is deceased, the relationship to the fungal 
infection will be recorded.  
See Section 20.7.1 for a detailed description of efficacy outcomes. 
16.16 Study Drug Dispensing, Collection and Treatment Compliance 
Evaluation 
For subjects who are not hospitalized, the study drug will be dispensed at Screening/Treatment 
Day 1. Subjects who are hospitalized and are later discharged from hospital will be dispensed their 
study drug at the time they are discharged. Study drug will be dispensed at each Treatment visit 
and will be supplied in bottles containing enough study drug to last until the next study visit. Study 
drug will be collected for treatment compliance evaluation on Treatment Days 3 to 5, Treatment 
Days 7 to 10,  every 14 days thereafter up to EoT and at unscheduled visits prior to EoT (see 
Section 14.5 for further details).   
16.17 Study Drug Dosing 
All enrolled subjects will receive an initial oral loading dose of 750 mg of SCY-078 (3 tablets of 
250 mg) BID during the first 2 days of treatment and then subsequent oral doses of 750 mg QD 
for up to 90 days. Oral treatment may be given on an inpatient or outpatient basis, as needed, and 
for as long as is clinically indicated, at the investigator´s discretion, but in no event for more than 
a total of 90 days of antifungal treatment.  
For subjects who are unable to take oral medications, tablets may be crushed and administered 
with approximately 8 oz./240 mL of water via an NG or PEG tube. The tube should be closed at 
least one hour before drug administration and be flushed with approximately 8 oz./240 mL of water 
before and after drug administration. 
Further details of the study treatment and dietary requirements for treatment administration are 
provided in Section 14.1 and Section 14.2, respectively.

16.18 Subject Diary Dispensing, Collection and Review 
Non-hospitalized subjects will complete a subject diary up to their EoT visit. The subjects will 
record the date/time of study medication dosing, daily symptoms, other medical concerns or 
complaints and concomitant medications.   
Subject diaries will be dispensed at Screening/Treatment Day 1 and will be reviewed on Treatment 
Days 7 to 10, every 14 days thereafter up to EoT, at EoT and at any unscheduled visit conducted 
prior to EoT. Subject diaries will be collected at EoT.  
16.19 Prior and Concomitant Medication Review 
All medications (including prescription and OTC medications, supplements, and herbal products) 
taken from 28 days before Screening/Treatment Day 1 through the EoT will be recorded on the 
eCRF. Only the use of antifungal medications, antibiotics for any reason or medications to treat an 
AE will be recorded after EoT and through the Week 6 Follow-up visit. See Section 15.0 for 
prohibited medications, medications to be administered with caution and further details for non-
study treatments. 
16.20 Adverse Event Monitoring 
AEs will be collected and evaluated from the time the informed consent is signed through the EoT. 
After the EoT and up to the last observation in the study (Week 6 Follow-up), new AEs will be 
collected only if deemed related to the study drug, if they are serious adverse events (SAEs), or if 
they are related to a fungal infection.  
See Section 18.0 for details regarding safety assessment and monitoring.

18.0 Safety Assessments and Monitoring 
18.1 
Definition of an Adverse Event 
An AE is any untoward medical occurrence associated with the use of a drug in humans, 
whether or not considered drug related. An AE can therefore be any unfavorable and 
unintended sign (including an abnormal laboratory finding), symptom or disease 
temporally associated with the use of a study drug/study intervention, whether or not 
related to the study drug/study intervention. 
Any laboratory abnormality that is deemed to be clinically significant in the opinion of the 
investigator will be considered an AE and should be recorded in the eCRF, whether or not 
it is related to the study drug. 
Stable chronic conditions that are present prior to clinical trial enrollment and do not 
worsen are not considered AEs and will be accounted for in the subject’s medical history. 
The following can be considered AEs: 
 An exacerbation of a pre-existing illness 
 An increase in frequency or intensity of a pre-existing episodic event or condition 
 A condition detected or diagnosed after the initiation of treatment with study 
medication, even though it may have been present prior to the start of the study 
 Continuous persistent disease or symptoms present at Baseline that worsen after 
signing the informed consent or following the initiation of treatment with study 
medication 
The following are not considered AEs: 
 Medical or surgical procedures (e.g., surgery, endoscopy, tooth extraction or 
transfusion); the condition that leads to the procedure is an AE 
 Pre-existing disease or conditions present or detected at the start of the study that 
do not worsen 
 Situations where an untoward medical occurrence has not occurred (e.g., 
hospitalizations for cosmetic surgery or elective surgery or social/convenience 
admissions)

 The disease being studied or signs or symptoms associated with the disease, unless 
more severe than expected for the subject’s condition or a worsening of the disease 
being studied 
18.2 
Definition of a Serious Adverse Event 
A SAE is defined as an AE meeting one of the following outcomes: 
 Death 
 Life-threatening event 
 Inpatient hospitalization or prolongation of existing hospitalization 
 Persistent or significant disability/incapacity or substantial disruption of the ability 
to conduct normal life functions 
 Congenital anomaly or birth defect 
Any other important medical event that may not result in one of the above outcomes may 
be considered a SAE when, based upon appropriate medical judgment, the event may 
jeopardize the participant and may require medical or surgical intervention to prevent one 
of the outcomes listed above. 
A life-threatening AE is any AE that places the subject, in the view of the investigator, at 
immediate risk of death from the AE as it occurred.  It does not include an AE that, had it 
occurred in a more severe form, might have caused death. 
18.3 
Events of Clinical Interest 
The following are considered events of clinical interest (ECIs), and must be reported by 
the site when it becomes aware of the ECI: 
 QTc >500 ms or a >60-ms change from Baseline, confirmed by repeat testing 
 ALT or AST >8 x ULN, if new compared to Baseline, confirmed by repeat testing 
 ALT or AST >5 x ULN for more than 2 weeks and if new compared to Baseline, 
confirmed by repeat testing 
 ALT or AST >3 x ULN and either total bilirubin >2 x ULN or INR >1.5 and if new 
compared to Baseline, confirmed by repeat testing 
 ALT or AST >3 x ULN, confirmed by repeat testing, with the appearance of fatigue, 
nausea, vomiting, right upper quadrant pain or tenderness, fever, rash, and/or 
eosinophilia (>5%)]

18.4 
Overdose 
This refers to the administration of a quantity of a medicinal product given per 
administration or cumulatively, which is above the maximum recommended dose 
according to the authorized product information.  
An overdose can occur if a subject has taken, accidentally or intentionally, a drug 
administered in a dose exceeding the protocol-specified dose.  An overdose must be 
reported within 24 hours of the site becoming aware of the overdose if such overdose 
occurs with an associated SAE. If an overdose occurs without an associated SAE, the 
overdose must be reported within 5 working days and documented in the subject diary and 
in the subject medical record. 
18.5 
Pregnancy 
Female subjects who become pregnant should be immediately discontinued from the study 
and followed up to determine the outcome of the pregnancy. The pregnancy must be 
reported to the Sponsor within 24 hours of the site becoming aware of the pregnancy.  If 
the pregnancy ends for any reason before the anticipated date, the investigator should notify 
the Sponsor. At the completion of the pregnancy, the investigator will document the 
outcome of the pregnancy. If the outcome of the pregnancy meets the criteria for immediate 
classification as an SAE (i.e., postpartum complication, spontaneous abortion, stillbirth, 
neonatal death or congenital anomaly), the investigator should follow the procedures for 
reporting an SAE. 
18.6 
Unexpected Adverse Event 
An AE is considered “unexpected” if it is not listed in the IB or is of greater specificity or 
severity than those that have been observed with the particular study drug being tested.  For 
example, under this definition, hepatic necrosis would be unexpected (by virtue of greater 
severity) if the IB referred only to elevated hepatic enzymes or hepatitis.  Similarly, 
cerebral thromboembolism and cerebral vasculitis would be unexpected (by virtue of 
greater specificity) if the IB listed only cerebral vascular accidents.  "Unexpected," as used 
in this definition, also refers to AEs that are mentioned in the IB as occurring with a class 
of drugs or as anticipated from the pharmacological properties of the drug but are not 
specifically mentioned as occurring with the particular drug under investigation.

18.7 
Grading of Adverse Events 
The severity (or intensity) of an AE refers to the extent to which it affects the subject’s 
daily activities and will be classified by the investigator as mild, moderate or severe using 
the following criteria: 
 Mild: Awareness of sign or symptom, but easily tolerated. Not likely to require 
medical attention. 
 Moderate: Discomfort enough to cause some interference with daily activity. May 
require medical intervention. 
 Severe: Intense enough to disrupt daily activities. Likely requires medical 
intervention. 
Clarification of the difference in meaning between “severe” and “serious” 
The term “severe” is often used to describe the intensity (severity) of a specific event (as 
in mild, moderate or severe myocardial infarction); the event itself, however, may be of 
relatively minor medical significance (such as severe headache). This is not the same as 
“serious”, which is based on the outcome or action criteria usually associated with events 
that pose a threat to life or functioning. Seriousness (not severity) serves as a guide for 
defining regulatory reporting obligations. 
18.8 
Causality Assessment 
The investigator will assess causality (i.e., whether there is a reasonable possibility that the 
study drug caused the event) for all AEs and SAEs. The relationship will be characterized 
using the following classification: 
 Related: The temporal relationship of the AE with the study drug makes causality 
possible and cannot be due to another cause such as other drugs, a surgical 
intervention or an underlying disease. 
 Not related: The temporal relationship of the AE with the study drug makes 
causality improbable and can be due to another cause such as other drugs, a surgical 
intervention or an underlying disease. 
18.9 
Adverse Event Collection Timeframe 
AEs will be collected and evaluated from the time the informed consent is signed through 
the EoT. After the EoT and up to the last observation in the study, new AEs will be

collected only if deemed related to the study drug, if they are SAEs, or if they are related 
to a fungal infection. 
All AEs reported by the subject or observed by members of the clinical staff will be 
evaluated by the principal investigator (PI) or qualified designee. The PI will attempt, if 
possible, to establish a diagnosis based on presenting signs and symptoms. The nature of 
the AE, time of onset relative to study drug administration, duration, severity, and 
relationship to treatment should be determined. Details of any corrective treatment must be 
recorded in the eCRF. The PI will determine whether any changes have occurred in 
baseline signs and symptoms. All AEs and SAEs will be collected in the eCRF. 
18.10 Serious Adverse Event Reporting Requirements 
All SAEs must be reported within 24 hours of the site becoming aware of the SAE. Any 
event that is serious, study drug-related, and unexpected as assessed by the medical monitor 
or the Sponsor will be submitted to the regulatory authorities in accordance with national 
regulatory laws and regulations. The PI will be responsible for reporting all SAEs that 
require reporting to the local Institutional Review Board/Ethics Committee (IRB/EC) in 
accordance with its regulations and guidelines. 
18.11 Adverse Event and Serious Adverse Event Follow-up 
All AEs and SAEs will be followed up to resolution (the subject’s health has returned to 
her baseline status or all variables have returned to normal) or until an outcome is reached, 
stabilization occurs (the investigator does not expect any further improvement or 
worsening of the event) or the event is otherwise explained, regardless of whether the 
subject is still participating in the study. All appropriate therapeutic measures should be 
undertaken and recorded. Where appropriate, medical tests and examinations will be 
performed to document resolution of the event(s). 
18.12 Serious Adverse Event Reporting – Procedures for Investigators 
Initial Reports and Follow-Up SAE Reports:  
To report an SAE, the SAE eCRF form within the Electronic Data Capture (EDC) system 
must be completed. All SAEs, whether or not deemed drug-related or expected, must be 
reported by the investigator or qualified designee within 24 hours of first becoming aware 
of the event. The investigator/qualified designee will enter the required information 
regarding the SAE into the appropriate form, which will automatically result in distribution 
of the information to the appropriate Sponsor contact.

Management 
19.1 
Data Collection and Reporting 
Data for this study will be collected using eCRFs. The investigator and study site staff will 
receive training regarding the completion of the eCRF. Visit-specific data should be 
entered into the eCRF and be ready for review as soon as possible, but no later than 5 days 
after each visit/time point. 
All protocol-required information collected during the study must be entered by the 
investigator or designated representative in the source documents and eCRF. All data entry, 
modification or deletion will be recorded indicating the individual subject, original value, 
the new value, the reason for change, who made the change, and when the change was 
made.  All data changes will be clearly indicated with a means to locate prior values. The 
investigator will maintain a list of individuals who are authorized to enter or correct data 
on the eCRFs. 
The investigator or designated sub-investigator, following review of the data in the eCRF, 
will confirm the validity of each subject’s data by signing the eCRF. 
19.2 
Study Monitoring 
Study progress will be monitored by the Sponsor or its representative as frequently as 
necessary to ensure adequate and accurate data collection, protocol compliance, and study 
conduct in accordance with accepted regulatory requirements. The PI must make all the 
subject data available to the monitor for review during the planned site monitoring visits. 
Arrangements for monitoring visits will be made in advance, except in emergency cases. 
19.3 
Investigator Study Files 
The PI is responsible for maintaining all study-related documents in study files. The 
Sponsor will notify the PI when retention of study files is no longer necessary. The 
following documents will be kept in the study files or be readily accessible: 
 original protocol and all amendments; 
 signed agreement or protocol; 
 signed and dated study staff roles and responsibilities log; 
 copy of the current curriculum vitae of the PI and of all sub-investigators;

19.4 
Retention of Records 
Essential documents should be retained until at least 2 years after the last approval of a 
marketing application and until there are no pending or contemplated marketing 
applications, or at least 2 years have elapsed since the formal discontinuation of the clinical 
development of the investigational product.  These documents should be retained for a 
longer period, however, if required by the applicable regulatory requirements or by an 
agreement with the Sponsor. 
The Sponsor will inform the PI/institution in writing of the need for record retention and 
will notify the PI/institution in writing when the trial-related records are no longer needed. 
An investigator who withdraws from the responsibility of maintaining study records or 
wishes to move them to a new location has the obligation to place them in safekeeping and 
to inform the Sponsor of their location. 
20.0 Analytical Plan 
All statistical processing will be performed using SAS® version 9.3 or later, unless 
otherwise stated.  
Descriptive statistics (i.e., number of subjects, mean, standard deviation, median, 
minimum, maximum) will be presented for all continuous variables; number and

percentage of subjects will be presented for categorical variables. For parameters measured 
over time, observed data and changes from baseline will be described for each time point.  
All analyses of the study results for SCY-078 will be descriptive. Unless otherwise stated, 
data will be analyzed as is with no imputation. 
A Statistical Analysis Plan (SAP) describing all statistical analyses in detail will be 
provided as a separate document.  
20.1 
Sample Size Determination 
This is an exploratory study and no formal sample size calculation was performed.  
A total of 30 subjects are estimated to be adequate for an assessment of the safety and 
tolerability of SCY-078 in subjects with candidiasis, including candidemia, caused by C. 
auris. 
20.2 
Analysis Populations 
Intent-to-Treat (ITT) Population: The ITT Population will include all subjects who are 
enrolled in the study. 
Per-Protocol (PP) Population: The PP Population will include all ITT subjects who 
receive at least 10 total days of antifungal therapy (SCY-078), who have an EoT assessment 
and who have no major protocol violations that would impact the assessment of efficacy.  
Safety Population: The Safety Population will include all subjects who receive at least 
one dose of study medication and have at least one safety assessment post baseline. 
PK Population: The PK Population will include all enrolled subjects who provide at least 
one PK sample. 
20.3 
Subject Disposition, Discontinuation, and Baseline Data 
Subject disposition in terms of the number and percentage of subjects enrolled by site will 
be tabulated. The number of subjects enrolled, number completing the study and reasons 
for discontinuation will be summarized. Subject demographics and baseline characteristics 
such as age, race, ethnicity, sex, weight, height, body mass index, country and other 
relevant parameters will be tabulated.  
Baseline is defined as the last non-missing assessment prior to the date (and time if 
appropriate) of the first dose of study drug. Change from baseline is defined as:post-
baseline value – baseline value.

Handling of Missing Data, Dose Adjustments, and Early 
Withdrawals 
For the efficacy analyses, subjects who do not have an EoT assessment will be assigned as 
treatment failures. For subjects who withdraw from the study early, every effort will be 
made to collect EoT visit information at the point of withdrawal. 
20.5 
Prior and Concomitant Medications 
Prior and concomitant medications will be coded using the World Health Organization 
Drug Dictionary terminology. The number and percentage of subjects taking each 
medication before and after the first dose of study drug will be tabulated. Medications taken 
and stopped prior to the first dose of study drug will be considered prior medications. 
Medications started on or before the FU visit date with missing stop dates or stop dates 
after the first dose of study drug will be considered concomitant medications.  
20.6 
Pharmacokinetics (PK Subset Only) 
20.6.1 Pharmacokinetic Assessments 
PK testing will be conducted for subjects who give their consent to participate in the PK 
portion of the study (the PK Subset). Up to three (3) blood samples will be collected at the 
following visits and sampling windows: Treatment Day 2 (one sample collected anytime 
post dosing), Treatment Days 3 to 5 (one sample collected predose on any of these days), 
and Treatment Days 7 to 10 (one sample collected predose on any of these days).  
20.6.2 Pharmacokinetic Analyses 
The PK analysis will be conducted on the PK Population. The concentration versus time 
data from the sparse PK samples collected in this study will be analyzed using a Pop PK 
model to estimate Cmax, AUC and CL/F, as applicable. Further analysis of possible 
metabolites may be performed.

Efficacy 
20.7.1 Efficacy Assessments 
20.7.1.1 
Clinical, Mycological and Global Outcomes 
Efficacy will be assessed primarily in terms of global success (defined as a complete or 
partial global (clinical and mycological) response) at EoT as determined by the DMC. 
Complete global response, partial global response, stable disease and progressive disease 
at EoT as determined by the DMC will be assessed as exploratory endpoints.  Global 
success, clinical success and mycological success at EoT as determined by the investigator 
will also be assessed as exploratory endpoints. 
Global Outcome 
Global outcome will be scored as global success (complete global response or partial global 
response) or global failure (stable disease or progressive disease) 
Global success: Global success is defined as a complete global response or a partial global 
response 
 Complete global response is defined as a complete clinical response (the resolution of 
all clinical signs and symptoms and/or radiological abnormalities from baseline 
attributable to the Candida auris infection) and a mycological response (mycological 
clearance (direct and/or negative cultures [when obtainable] and/or normal serological 
results [when appropriate]) 
 Partial global response is defined as a partial clinical response (major improvement of 
all clinical signs and symptoms and/or radiological abnormalities from baseline 
attributable to the Candida auris infection) and a mycological response (mycological 
clearance (direct and/or negative cultures [when obtainable] and/or normal serological 
results [when appropriate]) 
Global failure: Global failure is defined as either stable disease and/or progressive disease 
 Stable disease is defined as minor or no clinical improvement but without deterioration 
and/or unchanged serological response. 
 Progressive disease is defined as clinical deterioration necessitating alternative 
antifungal therapy or resulting in death, and/or worsened serological response, and/or 
persistence of fungal infection on the basis of culture, microscopic evaluation, or 
histopathological testing.

Clinical Outcome 
Clinical success: clinical success is defined as a complete clinical response (the resolution 
of all clinical signs and symptoms and/or radiological abnormalities from baseline 
attributable to the Candida auris infection) or a partial clinical response (major 
improvement of all clinical signs and symptoms and/or radiological abnormalities from 
baseline attributable to the Candida auris infection). 
Mycological Outcome 
Mycological success: mycological success is defined as a mycological response 
(mycological clearance (direct and/or negative cultures [when obtainable] and/or normal 
serological results [when appropriate]). 
 
20.7.1.2 
Recurrence and Survival 
Secondary efficacy assessments will include recurrence (after EoT) and survival.   
Survival: Survival will be determined on Day 42 and Day 84 (42 and 84 days after 
Screening/Treatment Day 1 [first dose of study drug]). This can be an in-person visit or a 
phone contact, and will document subject status only (alive or deceased). If subject is 
deceased, the relationship to the fungal infection will be recorded.  
Recurrence: Recurrence will be assessed by measuring recurrence of the baseline fungal 
infection 42 days after EoT (Week 6 FU). 
Recurrence is defined as global success at EoT but re-emergence of the baseline Candida 
auris infection during the post treatment follow-up.  Re-emergence of the Candida auris 
infection is required to be with the same species and involving the same site that was 
initially identified at Screening/Treatment Day 1. 
20.7.2 Efficacy Analyses 
The primary efficacy endpoint, the percentage of subjects with global success (complete 
or partial global response) as determined by the DMC at EoT, will be presented with a 95% 
confidence interval (CI) for the ITT and PP populations.  
Secondary and exploratory categorical endpoints will be presented with 95% CIs for the 
ITT and PP populations. 
The percentage of subjects surviving at 42 and 84 days after Screening/Treatment Day 1 
(first dose of study drug) will be presented for the ITT and PP populations; Kaplan-Meier 
curves will be presented.

subject ICF. The study will not be initiated until the PI obtains written approval of the 
protocol and the subject ICF from the appropriate IRB/EC, and copies of these documents 
are received by the Sponsor. Appropriate reports on the progress of this study will be made 
by the PI to the IRB/EC, medical monitor, and Sponsor in accordance with applicable 
government regulations and in agreement with policy established by the Sponsor. 
21.3 
Informed Consent  
The ICH issued guidelines to provide protection for human subjects in clinical 
investigations. The ICH Tripartite Guideline for Good Clinical Practice establishes the 
general requirements for informed consent. Each subject will be provided with oral and 
written information in a language they can understand that describes the nature and 
duration of the study. Before undergoing screening, each subject must consent in writing 
to study participation. The patient (or the subject’s legal representative) will sign and 
personally date the subject ICF. The person rendering consent will also sign and personally 
date the subject ICF as the person who obtained the consent of the subject. The original 
signed subject ICF will be retained with the study center’s records. Each subject will 
receive a copy of his/her signed subject ICF. In addition, the PI, or his or her designee, 
must document in the case history that informed consent was obtained before study 
participation.  
21.4

Substrates 
3A4 
In vitro, SCY-078 was an inhibitor of CYP3A mediated metabolism of midazolam, but 
was only a weak inhibitor of metabolism of testosterone. The clinical significance of this 
inhibition is unknown; caution should be exercised when administering SCY-078 with 
drugs known to be CYP3A sensitive substrates with narrow therapeutic index. 
Subjects receiving sirolimus, tacrolimus or warfarin are permitted for enrollment in the 
study and these medications may be administered concomitantly with SCY-078 with 
close monitoring. The administration of either sirolimus or tacrolimus should be offset 
by no less than 2 hours with the administration of SCY-078. At a minimum, blood levels 
of sirolimus, tacrolimus or PT/PTT/INR for subjects on warfarin should be measured 
after the first dose of SCY-078 and when the subject has received approximately 7 days 
of SCY-078 (at which time, SCY-078 concentrations will have reached steady state). 
Dosing adjustments and subsequent monitoring of sirolimus and warfarin should be 
undertaken in accordance with product prescribing information for the respective agents.
