Treated for Acute Bacterial Skin and Skin Structure Infection (ABSSSI) 
Phase of Development:  IV 
Study Centers: Multicenter study in up to 5 centers in the United States 
Central Facilities:  This list is maintained by the Sponsor 
Number of Subjects: 20 planned; 20 evaluable 
Principal Investigator:  
  
Study Period:  The estimated study period for the study will be approximately 3 weeks from first subject 
enrolled to last subject completed. 
Objectives:  Assess the safety and tolerability of two 1200-mg intravenous (IV) infusions of oritavancin when 
administered one week apart in subjects with acute bacterial skin and skin structure infection (ABSSSI). 
Methodology: This study will be a randomized, double-blind study.  Subjects with will be randomized (3:1) to 
receive either two doses of oritavancin or one dose of oritavancin and a single dose of placebo one week apart in

Test Drug, Dose and Mode of Administration:  The investigational drug oritavancin diphosphate (oritavancin) 
will be administered intravenously to all subjects. The dose is made up of three single-use vials, each containing 
400 mg of oritavancin and the inactive component mannitol. At the time of use, each vial should be reconstituted 
by adding 40 mL of Sterile Water for Injection, United States Pharmacopeia (USP). After reconstitution, 
oritavancin should be further diluted in approximately 1000 mL of 5% Dextrose Water Injection (D5W). 
On Day 1 of the study, subjects will be administered a single 1200-mg IV dose of oritavancin in 1000 mL D5W. 
On Day 8, an additional 1200-mg IV dose of oritavancin in 1000 mL D5W or placebo (D5W) will be 
administered. Oritavancin or placebo must be infused over 3 hours.  No other material or diluent may be 
substituted or concomitantly infused through the same IV line.  
Duration of Treatment: The study will consist of four periods: Screening (≤24 hours prior to Day 1), Pre-Dose 
(Day 1), Treatment (Day 1, Day 8), and Follow-up (Day 15, Day 22).   
Reference Therapy, Dose and Mode of Administration:  Five subjects will be administered a placebo 
(1000 mL of D5W) infused over 3 hours for the second dose. 
Criteria for Evaluation:

laboratory abnormalities, and the incidence of adverse events (AEs) and serious adverse events 
(SAEs). 
Secondary outcome:  
 
Clinical cure, as an assessment of efficacy, determined by the investigator at Day 8. 
Exploratory outcome: 
 
Antibody development following a single dose and multiple doses of oritavancin administration. 
Clinical evaluation time points: 
 
Assessment of safety (AEs) through Day 22  
 
Post-therapy efficacy evaluation at Day 8 
Efficacy:  Clinical cure 
Safety:  AEs, vital signs, clinical laboratory assessments 
Statistical Methods:  Approximately 20 ABSSSI subjects will be enrolled.  All 20 subjects will receive a single 
dose of oritavancin on Day 1, 15 subjects will receive a second 1200-mg dose of oritavancin and 5 subjects will 
receive a placebo infusion on Day 8.  
Sample size:  Twenty ABSSSI subjects were added to obtain safety information and to assess the potential for 
antibody production related to oritavancin administration. 
Analysis population: The subject populations are defined as follows:  
Intent-to-Treat (ITT) Population: The ITT population will include all subjects screened and randomized. 
Safety Population: All subjects dosed with IV oritavancin. The safety population will be the primary population 
for all the safety analyses. 
Descriptive statistics will be provided for demographic, baseline characteristics, medical history, prior and 
concomitant medications. Descriptive statistics include means, medians, standard deviations and ranges for 
continuous variables, as well as frequency and percentage for categorical variables. Summary tables and listings

INTRODUCTION 
This protocol describes a multicenter, double-blind, randomized study to evaluate the safety of 
two 1200-mg intravenous (IV) doses of Orbactiv™ for the treatment of subjects with an acute 
bacterial skin and skin structure infection (ABSSSI). 
This study will be conducted in compliance with Good Clinical Practices (GCP) including the 
Declaration of Helsinki and all applicable regulatory requirements. 
1.1. 
Background 
ABSSSIs are common infections that include cellulitis, major cutaneous abscesses, and wound 
infections.  ABSSSIs are inflammatory microbial invasions of the epidermis, dermis, and 
subcutaneous tissues [Dryden, 2009].  These infections are frequently caused by Gram-positive 
bacteria including methicillin-susceptible Staphylococcus aureus, methicillin-resistant S. aureus 
(MRSA), Streptococcus pyogenes, and other β-hemolytic streptococcal species and enterococci.  
The clinical complications of improperly treated or untreated ABSSSIs may include local 
expansion and spread, secondary bacteremia with potential for distant metastatic foci of 
infection, and systemic effects of bacterial infection. 
1.2. 
Oritavancin (ORBACTIV™) 
Oritavancin is a novel semi-synthetic, lipoglycopeptide antibiotic that has three mechanisms of 
action: 1) inhibition of the transglycosylation (polymerization) step of cell wall biosynthesis by 
binding to the stem peptide of peptidoglycan precursors; 2) inhibition of the transpeptidation 
(crosslinking) step of cell wall biosynthesis by binding to the peptide bridging segments of the 
cell wall; and 3) disruption of bacterial membrane integrity, leading to depolarization, 
permeabilization, and rapid cell death.  These multiple mechanisms contribute to the rapid, 
concentration-dependent bactericidal activity of oritavancin. 
Oritavancin has been approved by the Food and Drug Administration (FDA) for the treatment of 
adult subjects with ABSSSIs caused or suspected to be caused by susceptible isolates of 
designated Gram-positive microorganisms including MRSA [ORBACTIV™ Package Insert 
2016].   
1.2.1. 
Nonclinical Studies  
Oritavancin has been extensively studied pre-clinically.  The results from the safety, toxicology, 
pharmacokinetic (PK), and pharmacodynamic studies demonstrate that oritavancin does not 
induce any biologically significant toxicity.  An overview of relevant nonclinical study results is 
presented in the Investigator’s Brochure [Oritavancin Investigator’s Brochure Version 10].   
1.2.2. 
Clinical Pharmacology 
The PK of a single 1200-mg dose of oritavancin in ABSSSI subjects were determined from 
population PK analysis of pooled data from 297 adult subjects and are presented in Table 1.  At 
steady state, oritavancin exhibits linear PK at a dose up to 1200 mg.  The mean population-
predicted oritavancin concentration-time profile displays a multi-exponential decline and a long

terminal half-life (t½) of 245 hours.  Normal healthy volunteers administered a single 1200-mg 
dose of oritavancin experience higher oritavancin exposure when compared to subjects; mean 
Cmax was approximately 25% higher in healthy volunteers, and AUC0-∞ was approximately 40% 
higher in healthy volunteers when compared to subjects.

1.2.3. 
Clinical Studies 
An extensive clinical development program has been conducted to evaluate the safety and 
effectiveness of oritavancin comprising 4 completed Phase III studies, 4 Phase II studies, 14 
Phase I studies in healthy subjects, and one Phase I study in both healthy and hepatically 
impaired subjects.  Throughout the completed studies, IV oritavancin was administered to 3042 
individuals (2632 subjects and 410 healthy subjects) including 1075 adult subjects with ABSSSI 
treated with a 1200-mg single-dose regimen. [Oritavancin Investigator’s Brochure Version 10]. 
Efficacy and safety findings of the intended treatment dose in adult subjects with ABSSSI are 
summarized below:  
Efficacy 
The results from SOLO I and SOLO II in 1959 adult subjects demonstrated that a single 1200-
mg IV dose of oritavancin was clinically non-inferior to 7 to 10 days of IV vancomycin (1 g or 
15 mg/kg twice daily) using a pre-specified non-inferiority margin of 10% for both early clinical 
response and clinical cure at post-therapy evaluation.  The subject population was representative 
of ABSSSIs with S. aureus the common causative pathogen isolated; a large subset of subjects 
(N=405) had documented MRSA infections.  Efficacy in MRSA subjects was similar to that 
observed in the overall population for all endpoints. 
Safety 
The SOLO I and SOLO II studies demonstrated that a single 1200-mg IV dose of oritavancin 
was well tolerated and had a similar safety profile to 7 to 10 days of IV vancomycin treatment as 
demonstrated by the similar frequency and nature of treatment-emergent adverse events

Known and Potential Risks and Benefits 
SINGLE DOSE 
Twenty three clinical trials, including 4 Phase III, 4 Phase II, and 15 Phase I studies have been 
completed to date in which 3042 subjects were exposed to oritavancin.  The most common 
adverse events (>3%) by preferred term in either treatment group, in the SOLO I or SOLO II 
studies were nausea, headache, vomiting, cellulitis, diarrhea, constipation, infusion site 
extravasation, pyrexia and pruritus, as outlined in Table 2.

Serious hypersensitivity reactions have been reported with the use of oritavancin which could 
possibly have cross-sensitivity with hypersensitivity to glycopeptide drugs (e.g. vancomycin). 
In the Phase III ABSSSI clinical trials, the median onset of hypersensitivity reactions in 
oritavancin-treated subjects was 1.2 days and the median duration of these reactions was 2.4 
days. 
Infusion-related reactions or anaphylactoid reactions have been reported with oritavancin 
including pruritus, urticaria, or flushing.   
MULTIPLE DOSE 
In MDCO-ORI-15-02, a Phase I clinical study, 10 healthy volunteers received two doses of 
1200 mg oritavancin given 14 days apart.  Seven of the 10 subjects receiving oritavancin 
reported AEs during the second infusion with 5 prematurely discontinuing dosing during the 
second infusion.  The predominant symptoms in the 7 subjects who experienced AEs were

16 
 
musculoskeletal complaints (e.g., lower back pain) as well as gastrointestinal complaints 
(nausea, vomiting).  Fever or rash was not reported in any subject.  Symptoms developed in all 7 
subjects within 30 to 90 minutes from the start of the infusion and resolved in all within a few 
hours of study drug discontinuation.  None of the AEs experienced were deemed SAEs by the 
investigator, but in aggregate were considered by The Medicines Company (MDCO) as an 
important medical finding warranting of an IND Safety Report.  Further dosing in this study was 
voluntarily terminated by MDCO in order to investigate further the observed AEs during the 
second dose.  The key findings from these investigations are presented below. 
 
 No correlation between immunoglobulin levels and subjects experiencing an AE in 
MDCO-ORI-15-02 
 No pattern of cytokine/chemokine response in oritavancin-stimulated peripheral 
blood mononuclear cells from subjects with symptoms from MDCO-ORI-15-02 
 No lymphoproliferative response in oritavancin-stimulated peripheral blood 
mononuclear cells from subjects with symptoms from MDCO-ORI-15-02 
 No healthy subjects have developed a positive direct test for hemagglutination in the 
presence of drug testing and no subjects met clinical criteria for drug-induced 
autoimmune hemolytic anemia.  In ex vivo testing of healthy subject plasma samples, 
administration of oritavancin (and development of a positive indirect antiglobulin test 
[IAT]) appears to be associated with a weakly positive indirect test for 
hemagglutination in the presence of drug. 
 Administration of oritavancin to healthy subjects in 2 separate studies (MDCO-ORI-
15-02 and MDCO-ORI-15-01) was associated with development of a positive IAT in 
the majority of oritavancin-treated subjects; the IAT result reversed to negative in all 
subjects within 30 to 60 days. 
 None of the 15 subjects with ABSSSI infections treated with a single 1200-mg dose 
of oritavancin in the ongoing Study MDCO-ORI-14-03 (Warfarin Study in ABSSSI 
Subjects) in whom direct antiglobulin testing (DAT) or IAT was performed for up to 
14 days developed a positive DAT or IAT.  
 Results of recent post-marketing surveillance revealed 15 reports of subjects who 
received multiple doses of oritavancin.  Two reports described the onset of back pain 
during the second infusion of oritavancin.  In one report, the infusion was stopped and 
the subject was treated for symptoms; the subject was able to complete the infusion at 
a slower rate without further complications.  In the second report, the subject was 
treated for symptoms at the end of the dose. 
In summary, currently available data show that, in some healthy volunteer subjects, receipt of 
oritavancin was associated with a positive IAT (also called indirect Coombs test), which resolved 
over time, and a weakly positive indirect test for hemagglutination in the presence of drug with 
ex vivo testing .  There have been no positive DATs and no similar AEs reported following a 
single dose.  There is no evidence of autoimmune hemolytic anemia or definitive immune-related 
sequelae.  In view of the difference in the rate of development of positive IAT between healthy

subjects and infected subjects, we believe that it is most appropriate to further evaluate multiple-
dose administration in patients with ABSSSI infections rather than in healthy volunteer subjects.  
Subjects with ABSSSIs are to be enrolled to collect additional data on DAT and IAT, and to 
assess the safety of a second dose of oritavancin in these subjects in a controlled setting. 
A complete description of relevant risks of oritavancin can be found in the Investigator’s 
Brochure [Oritavancin Investigator’s Brochure Version 10] and the United States Package Insert 
(USPI).  More information regarding the events in Study MDCO-ORI-15-02 can be found in the 
Aggregate Report (dated August 26, 2015) of Infusion-Related Reactions Following the Second 
Infusion in Study MDCO-ORI-15-02 [Aggregate Report, 2015] and the subsequent follow up 
information dated July 22, 2016 [Follow-up Report, 2016]. 
1.3. 
Study Rationale  
Clinical studies in adult subjects with ABSSSI have demonstrated that a single 1200-mg IV dose 
of oritavancin was clinically non-inferior, well tolerated, and had a similar safety profile to 7 to 
10 days of IV vancomycin treatment (See Section 1.2.3 for additional details).  
The rationale for selecting the 1200-mg IV dose of oritavancin is described in Section 1.2.2.  The 
1200-mg dose of oritavancin is the United States (US) approved therapeutic dose. 
Subjects with ABSSSI will be enrolled in this study to obtain safety information of two 1200-mg 
IV infusions of oritavancin when administered one week apart.   
Study Population 
The study population will comprise of subjects who are at least 18 years of age with an ABSSSI 
suspected or confirmed to be caused by gram-positive pathogens.  An ABSSSI includes the 
following infections: wound infections, cellulitis/erysipelas, and major cutaneous abscess.

3. 
TRIAL DESIGN 
3.1. 
Type/Design of Trial 
This will be a Phase IV, randomized, double-blind trial in subjects with ABSSSI.  
Approximately 20 subjects will be enrolled at approximately 5 centers in the US.  Informed 
consent will be obtained from subjects before the initiation of any study-specific procedures.  
Eligible subjects will be randomized to receive either two doses of oritavancin one week apart or 
one dose of oritavancin and a single dose of placebo one week apart in a 3:1 ratio.  
The study will consist of four periods: Screening (≤24 hours prior to Day 1), Pre-Dose (Day 1), 
Treatment (Day 1, Day 8), and Follow-up (Day 15, Day 22).  
Safety assessments will include vital signs, laboratory abnormalities, and the incidence of AEs 
and SAEs (see Section 6 for assessment details).  
The maximum duration of a subject’s participation in this study is approximately 22 days after 
the first administration of oritavancin.  
The Sponsor will collect reticulocyte count, complete blood count, and manual blood smears pre- 
and post- the second infusion of oritavancin.  Infusion-related reactions will be considered an AE 
of Special Interest within the protocol and will be followed until resolution.  This designation 
will require that any reports (whether serious or non-serious) will be submitted to the Sponsor 
within 24 hours, along with a narrative and all necessary information to complete a 
CIOMS/MedWatch form, ensuring that complete and detailed information is obtained on the 
event.  Furthermore, any clinically significant lab data or adverse events occurring after the 
second dose will be required to be entered in the database within 24 hours in order to facilitate 
the Sponsor’s ongoing review of safety data. The Sponsor will be conducting ongoing review of 
the safety data within Study MDCO-ORI-16-02 (AEs, vital signs and labs) 
3.2. 
Primary Endpoint 
The primary endpoint of this trial is:  
 Safety of the administration of oritavancin in subjects will be assessed according to 
vital signs, laboratory abnormalities, and the incidence of AEs and SAEs. 
3.3. 
Secondary Endpoint 
The secondary endpoint of this trial is: 
 Clinical cure determined by the investigator at the Day 8 visit. 
3.4. 
Exploratory Endpoint 
The exploratory endpoint of this trial is: 
 Additional information collected will include (a) potential for antiglobulin 
development (direct and indirect) (b) change or increase in immunoglobulin profile 
and (c) development of drug-specific antibody in response to two 1200mg IV 
infusions of oritavancin.

Measures to Minimize/Avoid Bias 
3.5.1. 
Blinded Study Where Pharmacist is Unblinded 
This is a double-blind study design to minimize bias on study outcomes potentially introduced by 
the study procedures.  The placebo subjects also serve as a control for external factors that may 
exist at the time subjects are enrolled.  
Subjects will be given a subject identification (ID) number sequentially according to the date and 
time when subjects sign the informed consent (screening number).  The unblinded pharmacist 
will match the subject ID with the randomization schedule, which assigns treatment sequence 
based on 3:1 ratio.  The oritavancin and placebo infusion arms will be double-blind; all study 
staff will be blinded to the treatment with the exception of the unblinded pharmacist.   
The blinding of IV treatment assignment will be maintained until database lock.

TREATMENT OF SUBJECTS 
5.1. 
Study Medications 
Subjects will receive either two IV doses of 1200 mg oritavancin one week apart or will receive 
a single dose of 1200 mg oritavancin and a placebo infusion one week apart.  Oritavancin will be 
prepared by the study pharmacist/designee. 
5.1.1. 
Oritavancin 
Oritavancin will be supplied as a lyophilized powder in single-use glass vials. Each vial will 
contain 400 mg of oritavancin.  
Three 400 mg vials will be required for each subject receiving oritavancin.  At the time of use, 
each vial will be reconstituted by adding 40 mL of Sterile Water for Injection, United States 
Pharmacopeia (USP), to each 400 mg vial of oritavancin.  Vials reconstituted in this manner will 
provide a 10 mg/mL solution.  After reconstitution, oritavancin should be further diluted in 5% 
dextrose in water (D5W) to provide a total volume of approximately 1000 mL.  Since the 
solubility of oritavancin is highly dependent upon pH, no other material or diluent may be 
substituted or concomitantly infused through the same IV line.  The IV line should be flushed 
with D5W before and after; saline must not be used since it may cause precipitation. 
Subjects will receive either one or two 1200 mg IV oritavancin doses in 1000 mL of D5W 
administered as a constant rate IV infusion over 3 hours via a single dedicated peripheral IV line 
or a single dose of placebo, one week apart.  Oritavancin must be infused over 3 hours 
(6.7 mg/minute) to reduce the potential for histamine like infusion reactions or phlebitis.   
5.1.2. 
Placebo  
Placebo will be 1000 mL of D5W infused over 3 hours via a single dedicated peripheral IV line. 
5.1.3. 
Packaging and Labeling  
Oritavancin will be provided by the Sponsor.  Infusion bags of D5W will be provided by the 
study site pharmacy.  
Medication labels will comply with regulatory requirements.  The storage conditions for each 
medication provided will be described on the medication label. 
5.1.4. 
Storage  
Oritavancin lyophilized powder should be stored in a secure cabinet or other enclosure at 
controlled room temperature (20°C to 25°C; 68°F to 77°F).  Diluted IV solution in an infusion 
bag should be used within 6 hours when stored at room temperature, or used within 12 hours 
when refrigerated at 2 to 8°C (36 to 46°F).  The combined storage time (reconstituted solution in 
the vial and diluted solution in the bag) and 3-hour infusion time should not exceed 6 hours at 
room temperature or 12 hours if refrigerated (see Pharmacy Manual).  Access should be strictly 
limited to the study pharmacists and their designees.

5.1.5. 
Accountability 
The investigator or designee must maintain an inventory record of all study medications received 
and administered to assure the regulatory authorities and the Sponsor that the drugs will not be 
dispensed to any person who is not a subject under the terms and conditions set forth in this 
protocol.  Drug accountability forms and/or specific instructions can be found in the Pharmacy 
Manual. 
The oritavancin supplied for use in this study is to be prescribed only by the principal 
investigator or designated sub-investigators and may not be used for any purpose other than that 
outlined in this protocol. 
During the study all used oritavancin containers (e.g., empty vials/bottles) will be kept until the 
monitor has reviewed the accountability records. 
All used and unused oritavancin supplied for this study will be destroyed on site once 
inventoried and the monitor has reviewed the accountability records.  In the event that 
oritavancin needs to be returned for any other reason, the site will receive a written request 
listing drug lot number(s) to be returned and the reason for the return request. 
5.1.6. 
Product Complaints 
Sites are required to report any product complaints to MDCO immediately but no later than 24 
hours from the time of awareness, by phone or e-mail as follows:

 An indication that there is an unexpected physical change in any part of the container 
(this includes the bottle, any part of the seal, the cap or the label).  
 An indication that the product is mislabeled.  
 An indication that there is an unexpected physical change of the product or container 
once the product is diluted or reconstituted (the container includes the vial, bag, IV 
line, syringe or any other item that is in contact with the product).  
 An indication that the product is falsified, tampered with, or adulterated.  
 An indication that the product did not meet its pharmacologic effect, i.e. lack of 
efficacy.  
 Medical device incidents 
5.2. 
Concomitant Medications  
Any concomitant medications will be recorded in the electronic case report form (eCRF) 
according to the Schedule of Events. 
5.2.1. 
Prohibited Concomitant Medications 
There are no prohibited concomitant medications for this study. 
5.2.2. 
Permitted Concomitant Medication(s) 
Subjects enrolled and treated with oritavancin may receive additional antibiotic therapy with 
Gram-negative coverage if necessary. 
5.3. 
Medical Management Guidelines 
Other interventions to optimize the care of subjects will be left to the discretion of the attending 
physician and investigator.  These include surgical/nonsurgical debridement of devitalized tissue, 
removal of prosthetic material, incision and drainage, suture removal, percutaneous aspiration, 
packing, dressings, or irrigation with normal saline to remove superficial slough, excess exudate 
or visible debris. Standard of care therapy (such as daily superficial debridements and dressing 
changes) are allowed.  
The investigator will be given guidance to stop, slow, or possibly even interrupt and restart an 
infusion should an infusion-related reaction occur. In addition, at the investigator’s discretion, 
patients who experience an infusion-related reaction may be given diphenhydramine or 
dexamethasone as treatment(s) for their symptoms.  In Study MDCO-ORI-15-02, all adverse 
events observed that were associated with the second dose occurred within 30-90 minutes of the 
start of the 3 hour infusion and resolved within a few hours after the end of infusion. Therefore 
all infusions must be administered in the presence of a medically qualified team member and 
subjects will be required to remain in the administration setting for a minimum of 3 hours 
following the completion of the second IV infusion or until any AEs that occur are resolved or 
stable.  
If a subject is classified as a treatment failure by the investigator at any time, the subject may be 
administered alternative antibiotic therapy according to clinical judgment.

5.3.1. 
Gram-negative pathogen ABSSSI infections 
Subjects enrolled and treated with oritavancin before culture results are available and found to 
have a Gram-negative pathogen may receive additional antibiotic therapy with Gram-negative 
coverage.  
5.4. 
Restrictions 
Subjects will be encouraged to continue their usual diet and level of activity, as dictated by their 
clinical condition.  Activities that would impact clinical outcome should be avoided during the 
study period. 
5.5. 
Blinding 
5.5.1. 
Method and Maintenance of Blinding 
This is a randomized, double-blind study.  Subjects will be given a subject identification (ID) 
number sequentially according to the date and time when subjects sign the informed consent 
(screening number).  The unblinded pharmacist will match the subject ID with the randomization 
schedule, which assigns treatment sequence based on 3:1 ratio.  The oritavancin and placebo 
infusion arms will be double-blind; all study staff will be blinded to the treatment with the 
exception of the unblinded pharmacist.   
5.6. 
Unblinding 
The blinding of IV treatment assignment will be maintained until database lock.  However, if a 
subject has a safety event that meets any of the protocol-defined stopping criteria, the subject’s 
treatment assignment will be unblinded after determining relatedness to the study drug.  The 
blind may also be broken for a specific subject only in the case where knowledge of the 
treatment assignment is deemed essential to subject safety or the occurrence of a SAE that, in the 
opinion of the investigator, cannot be adequately treated without knowing the identity of the 
study drug.  Any intentional or unintentional breaking of the blind should be immediately 
reported to the Sponsor.  
The principal investigator will be provided with instructions/envelopes for subject unblinding.

PROTOCOL ASSESSMENTS 
7.1. 
Assessment of Safety  
When blood draws and vital signs are done at the same time point, the following sequence 
should be followed: 1) vital sign assessment 2) blood draw for lab tests. 
7.1.1. 
Adverse events 
Subjects will be carefully monitored for AEs by the investigator during the designated study 
period (see Section 8 for details).   
7.1.2. 
Physical examinations 
A physical exam will include head, eyes, ears, nose, throat (HEENT), heart, lungs, abdomen, 
skin, and extremities. BMI will be calculated based on height and weight collected at the 
Screening Visit. 
7.1.3. 
Vital signs

7.2. 
Assessment of Efficacy 
Definition of clinical response 
 A subject is classified as “success” if all of the following are met: 
 Cessation of spread or reduction of the lesion defined as: Cessation of spread of the 
redness, edema, and/or induration, or reduction in size (length, width, and area) of the 
redness, edema, and/or induration such that the size of the lesion is less than or equal 
to the size at baseline 
 Resolution (absence) of fever (temperature <37.7°C)  
 No rescue antibiotic medication 
Investigator assessment of clinical cure: 
At Day 8:  Complete or nearly complete resolution of baseline signs and symptoms of the 
primary infection such that no further treatment with antibiotics is needed. 
A subject cannot be classified as clinical cure if: 
 Subject did not fulfill the criteria for clinical cure above 
 Investigator assignment of failure any time prior to Day 8 
 Subject dies (all-cause mortality) from the start of administration of oritavancin  
 Incision and drainage after 48 hours of treatment that was unplanned prior to 
enrollment, with the exception of cellulitis where there is a conversion into an abscess 
or when an extension of the original incision is indicated 
 Initiation of non-study antibacterial drugs for treatment of other infections unless 
antibiotic lacks efficacy in the treatment of ABSSSI 
 Subjects who otherwise do not meet the definition of clinical cure (e.g., lost to 
follow-up; oritavancin discontinued secondary to adverse reaction) 
A subject who is not classified as clinical cure will be classified as failure. 
7.3. 
Assessment of Pharmacokinetics 
Blood samples for pharmacokinetic analysis of oritavancin will be collected on Days 8 pre-dose, 
at 3 (end of infusion) and 6 hours after the start of study drug infusion. Subjects will have blood 
collected for PK on Day 15 and Day 22 as well.

ADVERSE EVENTS 
8.1. 
Definitions  
8.1.1. 
Adverse Event  
An AE is defined as any untoward medical occurrence in a subject or clinical investigation 
subject administered a medicinal product and which does not necessarily have a causal 
relationship with this treatment.  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 medicinal product, whether or not considered related to the medicinal product.  
Planned hospital admissions and/or surgical operations for an illness or disease that existed 
before the study drug was given or the subject was randomized in a clinical study are not to be 
considered AEs. 
Subjects experiencing AEs should be followed clinically until their health has returned to 
baseline status or until all parameters have returned to normal or have otherwise been explained.  
It is expected that the investigator will provide or arrange appropriate supportive care for the 
subject if necessary.  
8.1.1.1. 
AE Severity  
The severity of an AE will be assessed by the investigator.  The investigator should ensure that 
any subject experiencing an AE receives appropriate medical support until the event resolves. 
AEs will be graded on a 3-point scale and reported as indicated on the CRF.  The intensity of an 
AE is defined as follows: 
1 = Mild: Discomfort noticed, but no disruption to daily activity. 
2 = Moderate: Discomfort sufficient to reduce or affect normal daily activity. 
3 = Severe: Inability to work or perform normal daily activity. 
8.1.1.2. 
Study Drug Causality  
The relationship of an AE to study treatment will be assessed with consideration to the following 
criteria: 
 Temporal relationship to the initiation of study medication 
 Response of the event to withdrawal of study medication 
 AE profile of concomitant therapies 
 Clinical circumstances during which the AE occurred 
 Subject’s clinical condition and medical history 
Categorization of causality will be designated by the investigator as stated below: 
1. Unlikely related - Lack of reasonable possibility of a causal relationship - causal 
relationship between the event and the Investigational Medicinal Product (IMP).  This 

Oritavancin diphosphate                                               Clinical Study Protocol MDCO-ORI-16-02 
The Medicines Company 
 
 
Confidential 
                  
38 
 
means that there are little to no facts (evidence) or arguments to suggest a causal 
relationship. 
2. Reasonable possibility - Reasonable possibility of a causal relationship - causal 
relationship between the event and the IMP.  This means that there are facts (evidence) or 
arguments to suggest a causal relationship. 
8.1.2. 
Serious Adverse Event 
An SAE is any untoward medical occurrence that at any dose: 
 Results in death, 
 Is life-threatening, i.e., the subject was, in the opinion of the investigator, at 
immediate risk of death from the event as it occurred (it does not include an event 
that, had it occurred in a more severe form, might have caused death), 
 Results in a significant, persistent or permanent change, impairment, damage or 
disruption in the subject's body function/structure, physical activities and/or quality of 
life, 
 Requires in-subject hospitalization or prolongs hospitalization, 
 Is a congenital anomaly/birth defect, or 
 Is another medically significant event that, based upon appropriate medical judgment, 
may jeopardize the subject and may require medical or surgical intervention to 
prevent one of the outcomes listed above (e.g., allergic bronchospasm requiring 
intensive treatment in an emergency department or home, blood dyscrasias or 
convulsions that do not result in hospitalization, or the development of drug 
dependency or drug abuse). 
A distinction should be drawn between serious and severe AEs.  Severity is an estimate or 
measure of the intensity of an AE, while the criteria for serious AEs are indications of 
adverse subject outcomes for regulatory reporting purposes.  A severe AE need not 
necessarily be considered serious and a serious AE need not be considered severe.  For 
example, nausea that persists for several hours may be considered severe nausea, but not an 
SAE.  On the other hand, a myocardial infarction (MI) that may be considered minor could 
also be an SAE if it prolonged hospitalization. 
When death occurs with an SAE, the cause of death must be reported as an SAE. “Fatal” will 
be reported as the outcome for these events. 
8.1.3. 
Medication Errors  
Medication error refers to any unintended error in the dosing and administration of the study 
drug as per instructions in the protocol.  Medication errors generally fall into 4 categories as 
follows: 
 wrong study medication 
 wrong dose (including dosing regimen, strength, form, concentration, amount); 

Oritavancin diphosphate                                               Clinical Study Protocol MDCO-ORI-16-02 
The Medicines Company 
 
 
Confidential 
                  
39 
 
 wrong route of administration; 
 wrong subject (i.e., not administered to the intended subject) 
Medication errors include occurrences of overdose and underdose of the study product(s), and 
misuse. 
Overdose:  Administration of a quantity of the study product given per administration or per day 
which is above the maximum recommended dose according to the reference safety information 
or protocol for the investigational product or comparator as applicable.  This also takes into 
account cumulative effects due to overdose.  
Underdose: Administration of a quantity of the study product given per administration or per 
day which is under the minimum recommended dose according to the reference safety 
information or protocol for the investigational product.  
Misuse: Intentional and inappropriate use of a medicinal product not in accordance with the 
prescribed or authorized dose, route of administration, and/or the indication(s) or not within the 
legal status of its supply (e.g., without prescription for medicinal products subject to medical 
prescription). 
8.1.4. 
Adverse Event of Special Interest (AESIs) 
An adverse event of special interest (serious or non-serious) is one of scientific and medical 
concern specific to the Sponsor’s product or program, which warrants ongoing monitoring and 
rapid communication by the investigator to the Sponsor. Such an event might warrant further 
investigation in order to characterize and understand it.  
The following AESIs have been identified for the study drug in this protocol: 
 Hypersensitivity/Infusion Related Reaction 
 Pseudomembranous colitis/Clostridium difficile-associated diarrhea 
 Osteomyelitis 
8.2. 
Procedure for Non-Serious Adverse Event Recording 
All non-serious AEs that occur during the designated study period (from signing the informed 
consent to 21 days following initial oritavancin administration) must be assessed and recorded on 
the source documents and eCRF, regardless of causal relationship to the study drug. 
8.3. 
Procedure for Serious Adverse Event Reporting 
All SAEs that occur during the designated study period (from signing the informed consent to 21 
days following initial oritavancin administration) must be reported to MDCO within 24 hours of 
awareness of the event using the provided study specific SAE/AESI Report Form.  The 
completion and processing of the SAE/AESI Report Form (paper) should follow the instructions 
provided in the SAE/AESI Report Form completion guidelines.  In addition to completing the 
SAE/AESI Report Form, each SAE/AESI must be entered on the appropriate page of the eCRF.   
When death occurs with an SAE, the cause of death must be reported as an SAE.  “Fatal” will be 
reported as the outcome for these events 

Oritavancin diphosphate                                               Clinical Study Protocol MDCO-ORI-16-02 
The Medicines Company 
 
 
Confidential 
                  
40 
 
The investigator must assess the causality for each SAE/AESI. 
MDCO will contact the investigator, if necessary, to clarify any of the event information. The 
investigator should provide any follow-up information for the event to MDCO as soon as it 
becomes available. 
If the investigator is notified of a SAE/AESI that occurs during the post-study period, that he or 
she wishes to report to the Sponsor (e.g., an event suspected to be causally related to study drug), 
the event should be reported through the process described above.  
Where appropriate, if required by local regulations or procedures, the investigator should report 
these events to the Institutional Review Board (IRB)/Ethics Committee (EC) and/or national 
regulatory authority in addition to the Sponsor. 
8.4. 
Procedure for Medication Error Reporting For Study Products 
Medication errors, with or without an associated AE, need to be recorded as medication errors in 
the eCRF as described in Section 8.2. 
Medication errors with an associated SAE need to be recorded as medication errors in the eCRF 
and reported to the MDCO Global Pharmacovigilance as described in Section 8.3. 
A mis-dosing protocol deviation (refer to Section 12.3) would need to be reported as a 
medication error if it was an “unintended error” as defined in Section 8.1.3. 
8.5. 
Procedure For Reporting Adverse Events Of Special Interest 
(AESIs) 
All AESIs should be reported to MDCO within 24 hours.  The SAE/AESI Report Form should 
be utilized for reporting the AESI even if a serious outcome may not apply.  The SAE/AESI 
Report Form should indicate that the reported event is an AESI.  The site will also be asked to 
complete a targeted questionnaire which obtains more information about the specific event. 
8.6. 
Procedure For Reporting Pregnancies 
Occurrences of pregnancy/lactation exposure in a study subject or study subject’s partner, 
including pregnancies detected anytime from administration of oritavancin until 60 days after 
administration of oritavancin, must be reported within 24 hours using the Pregnancy Reporting 
form.  In cases where a pregnancy occurs with an SAE, the SAE Reporting Form should be used 
to report the SAE/AESI and the Pregnancy Reporting Form should be used to report the 
pregnancy.  Any spontaneous abortion must be captured as an SAE.  When a pregnancy occurs 
without any intercurrent SAE, the Pregnancy Reporting Form may be submitted alone.  Follow-
up through pregnancy outcome is required if a pregnancy is detected during this study. 
The Medicines Company or its designee will contact the investigator, if necessary, to clarify any 
of the pregnancy information.  The investigator will provide follow-up information to MDCO or 
its designee as soon as it becomes available.  Additionally, if required by local regulations or 
procedures, the investigator will report pregnancies to the IRB/EC and/or national or local 
regulatory authorities.

8.7. 
Ongoing Safety Monitoring and Stopping Rules 
The Sponsor will be conducting ongoing review of the safety data (AEs, vitals and labs).  The 
study will be terminated if any of the following criteria are met: 1) any death which is considered 
possibly related to oritavancin or 2) any two or more subjects who experience any serious 
adverse event possibly related to oritavancin or 3) any three or more subjects who experience 
any non-serious AE which is severe in intensity and considered possibly related to oritavancin. 
8.8. 
Procedure For Reporting Special Situations 
If there is an occurrence of a Special Situation event, defined in Section 8.1.4, report this 
occurrence to the Sponsor as per Section 8.3, Procedure for Serious Adverse Event Reporting.

DATA COLLECTION 
An electronic data capture (EDC) system will be used for this trial.  All users will be trained on 
the technical features of the EDC as well as the content of the eCRF by qualified personnel prior 
to gaining access to the EDC.  A User ID/Password will be granted after training.  This ID is not 
to be shared amongst the study staff.  All users must have a unique account to enter or review 
data.  The eCRF should be filled out by the site 3 days after the Day 15 visit and 3 days after the 
Day 22 visit.  Any Clinically Significant lab data or AEs occurring after the second dose should 
be entered within 24 hours in order to facilitate the Sponsor’s ongoing review of safety data.  It is 
not expected that the eCRF will serve as source for any data collected in this trial.  If there is a 
reason for a site to do so, it must be approved by DCO and documented in the site files. 
Prior to the database being locked, the investigator or designee will review, approve, and 
sign/date each completed eCRF.  This signature serves as attestation of the investigator’s 
responsibility for ensuring that all data entered into the eCRF are complete, accurate, and 
authentic.  After the end of the trial, a copy of the data will be provided to the site.  This copy 
will contain the final data, an audit trail of activity on the data, and any queries and answers that 
were posted for data clarification.

STATISTICAL PLAN 
This is a 20 subject, randomized, double-blind trial.  Subjects with ABSSSI will be included in 
this study.  Subjects will be recruited from approximately 5 centers in the US.  Subjects that 
qualify for entry into the study will be randomly assigned in a 3:1 ratio to receive either two IV 
doses of 1200 mg oritavancin one week apart or a single dose of 1200 mg oritavancin and a 
placebo infusion one week apart.  The primary objective of this study is to evaluate the safety 
and tolerability of two 1200-mg IV infusions of oritavancin when administered one week apart.  
Statistical methods and data presentation will be described in more detail in the Statistical 
Analysis Plan (SAP) document. 
10.1. 
Sample Size  
Approximately 20 ABSSSI subjects will be evaluated to obtain safety information including the 
potential for antibody production related to oritavancin administration.  Study subjects will be 
randomized in a 3:1 ratio to all receive oritavancin with the first dose (20 subjects) and receive 
oritavancin with the second dose (15 subjects) or placebo (5 subjects).  
10.2. 
Randomization 
Subjects will be randomly assigned in a 3:1 ratio to receive either two doses of oritavancin one 
week apart or one dose of oritavancin and one dose of placebo one week apart.   
10.3. 
General Statistical Considerations and Definitions  
10.3.1. 
General Statistical Methods 
Continuous variables will be summarized using mean, standard deviation (SD), median, quartiles 
(first [Q1] and third [Q3]), minimum, and maximum.  Categorical variables will be summarized 
using frequency and percentage.   
10.3.2. 
Analysis Population 
Two populations will be used for data analyses and/or presentation.   
10.3.2.1. Intent-to-Treat (ITT) Population  
The ITT population will include all subjects screened and randomized.  This will be the primary 
population for efficacy analysis. 
10.3.2.2. Safety Population 
The safety population will include all subjects who are dosed with IV oritavancin.  This will be 
the primary population for safety analysis.  
10.3.3. 
Analysis Windows and Baseline 
The observational period for the study includes Day 22±2 days.  Any event occurring beyond the 
defined observational period, even if collected on the CRF, will not be included in the planned

statistical analysis.  However, all data, including that reported after the defined observational 
period, will be included in the subject data listings.   
Unless otherwise specified, the last evaluation prior to the initiation of dosing will be considered 
the “Baseline” evaluation for analysis of data.  
10.3.4. 
Missing Data Handling 
Unless otherwise specified, missing data will not be imputed and will be excluded from the 
associated analysis.  
10.4. 
Statistical Analyses 
All summaries will be presented by group.   
10.4.1. 
Demographic and Background Characteristics 
Subject demographics and baseline characteristics will be summarized using the Safety 
Population.   
10.4.2. 
Prior and Concomitant Medications 
Separate summaries of prior and concomitant medications will be provided for the Safety 
Population.  Prior medications are those received before the initiation of dosing on Day 1 while 
concomitant medications are those received after.  Medications will be coded with the World 
Health Organization (WHO) Drug Dictionary Enhanced.  
10.4.3. 
Safety Analysis 
10.4.3.1. Adverse Events  
The Medical Dictionary for Regulatory Activities (MedDRA) will be used for coding AEs.  An 
AE (classified by system organ class and preferred term) that occurs during the treatment period 
will be counted as a TEAE either if it is not present at baseline or if it is present at baseline but 
increased in severity during the treatment period or follow-up period. 
The number (percentage) of subjects reporting TEAEs for each preferred term will be tabulated 
by system organ class, by system organ class and severity, and by system organ class and 
relationship to oritavancin.  If more than one event occurred with the same preferred term for the 
same subject, the subject will be counted only once for that preferred term using the most severe 
or related occurrence for the summary by severity, or relationship to study drug, respectively.   
Listings of SAEs and AEs leading to treatment or study discontinuation will also be provided.   
10.4.3.2. Clinical Safety Laboratory Tests  
Clinical safety laboratory values and changes from baseline, including direct and indirect 
antiglobulin, immunoglobulin panel, and oritavancin antibody assay, will be summarized 
descriptively. Clinically significant values will also be flagged in a listing.

RECORDS RETENTION 
Current FDA regulations require all investigators participating in clinical study drug trials to 
maintain detailed clinical data for one of the following periods: 
 At least 2 years following the date on which a New Drug Application is approved by 
the FDA, or 
 Two years after the Sponsor notifies the investigator that no further application is to 
be filed with the FDA. 
Similarly, current EU Directives / Regulations and International Conference on Harmonization 
(ICH) guidelines collectively require that essential clinical trial documents (including case report 
forms) other than patient’s medical files must be retained for the following time period: 
 — for at least 15 years after completion or discontinuation of the trial,  
 — or for at least two years after the granting of the last marketing authorisation in the 
European Community and when there are no pending or contemplated marketing 
applications in the European Community,  
 — or for at least two years after formal discontinuation of clinical development of the 
study drug.  
Subject's medical files should be retained in accordance with applicable legislation and in 
accordance with the maximum period of time permitted by the hospital, institution or private 
practice.  The documents can be retained for a longer period, however, if required by the 
applicable regulatory requirements or by agreement with the sponsor.  
To comply with these requirements, the investigator will not dispose of any records relevant to 
this study without either (1) written permission from the Sponsor or (2) providing an opportunity 
for the Sponsor to collect such records.  The investigator shall take responsibility for maintaining 
adequate and accurate hard copy source documents of all observations and data generated during 
this study, including the hard copy or discs received from the Sponsor of the final data.  Such 
documentation is subject to inspection by the Sponsor or its agents, the FDA and/or other 
regulatory agencies.

QUALITY CONTROL AND QUALITY ASSURANCE  
12.1. 
Monitoring  
The Sponsor has ethical, legal and scientific obligations to carefully follow this study in 
accordance with established research principles and applicable regulations.  The investigator, as 
part of his responsibilities, is expected to cooperate with the Sponsor in ensuring that the study 
adheres to the protocol and GCP requirements.   
As part of a concerted effort to fulfill these obligations, the Sponsor's monitor will visit the 
center(s) during the study in accordance with the Monitoring Plan set forth for this trial.  The 
investigator will permit the Sponsor to monitor the study as frequently as is deemed necessary 
and provide access to medical records/source documents to ensure that data are being recorded 
adequately, that data are verifiable, and that protocol adherence is satisfactory.   
12.2. 
Auditing  
The Sponsor may conduct audits at the study centers.  Audits will include, but not be limited to, 
study drug supply, presence of required documents, the informed consent process, and 
comparison of eCRFs with source documents.  The investigator agrees to permit audits 
conducted at a reasonable time in a reasonable manner. 
Regulatory authorities worldwide may also inspect the investigator during or after the study.  
The investigator should contact the Sponsor immediately if this occurs, and must permit 
regulatory authority inspections. 
12.3. 
Protocol Deviations  
This study will be conducted as described in this protocol, except for an emergency situation in 
which the protection, safety, and well-being of the subject requires immediate intervention, 
based on the judgment of the investigator (or a responsible, appropriately trained professional 
designated by the investigator).  In the event of a significant deviation from the protocol due to 
an emergency, accident, or mistake, the investigator or designee must contact the Sponsor 
(Clinical Project Director, Medical Director or Clinical Research Associate) at the earliest 
possible time.  This will allow an early joint decision regarding the subject’s continuation in the 
study.  The investigator and the Sponsor will document this decision.  The IRB/EC will be 
informed of all protocol changes by the investigator in accordance with the IRB/EC established 
procedure.  No deviations from the protocol of any type will be made without complying with all 
the IRB/EC established procedures. 
Any protocol deviations that will affect the subject’s safety or the study objectives may be 
considered a major protocol deviation upon review by the Sponsor.  In addition, any of the 
following deviations will be considered major protocol deviations: 
The following Protocol Deviations will require additional information in the eCRF explaining 
why the deviation occurred and what will be done to prevent it from re-occurring:  
 All Inclusion criteria violation 
 All Exclusion criteria violation

 PK sample not collected due to site error 
 Mis-Dosing: Subject was not dosed per the protocol instructions and therefore, greater 
than 120% or less than 80% of the correct dose was administered 
 
*If the mis-dosing was unintended, i.e. a medication error, the error should be reported as 
per instructions in Section 8.4, Procedure for Medication Error Reporting.

procedures and/or guidelines, the US Food and Drug Administration (FDA) regulations, the ICH 
GCP guidelines, the Declaration of Helsinki and other local regulations, as applicable. 
13.1. 
Informed Consent 
Written informed consent will be obtained from all subjects (or their guardian or legally 
authorized representative) or, as per IRB guidelines, before any study-related procedures 
(including any pre-treatment procedures) are performed.  The investigator(s) has both ethical and 
legal responsibility to ensure that each subject (and their guardian or legally authorized 
representative) being considered for inclusion in this study is given a full explanation of the 
protocol.  This shall be documented on a written informed consent form, which shall be 
approved by the same IRB or EC responsible for approval of this protocol.  Each informed 
consent form shall include the elements required by ICH, Part E6, Section 4.8 and any applicable 
local regulations.  The investigator agrees to obtain approval from the Sponsor of any written 
informed consent form used in the study, preferably prior to submission to the IRB or EC.  
Once the appropriate essential information has been provided to the subject and fully explained 
by the investigators (or a qualified designee) and it is felt that the subject understands the 
implications of participating, the subject and the investigator (or designee) shall sign the IRB- or 
EC-approved written informed consent form.  The subject shall be given a copy of the signed 
informed consent form, and the original shall be filed appropriately, according to the institution.  
A second copy may be filed in the subject's medical record, if allowed by the institution. 
13.2. 
Institutional Review Board/Ethics Committee  
This protocol, the written informed consent form and any materials presented to subjects shall be 
submitted to the IRB or EC identified with this responsibility.  Notification in writing of 
approval must come from the IRB or EC chairman or secretary, to the investigator, either as a 
letter or as a copy of the appropriate section of the IRB or EC meeting minutes where this 
protocol and associated informed consent form were discussed.  The investigator will not 
participate in the decision.  If the investigator is an IRB or EC member, the written approval 
must indicate such non-participation in the voting session.  The investigator will submit status 
reports to the IRB or EC as required by the governing body.  The IRB or EC must be notified by 
the investigator in writing of the interruption and/or completion of the study; the investigator 
must promptly report to the IRB or EC all changes in research (protocol amendments) and will 
not make such changes without IRB or EC approval, except where necessary to eliminate 
apparent immediate hazards to human subjects.  In cases where it is necessary to eliminate 
immediate hazards to subjects, the IRB or EC must then be notified of the change as per local 
requirements.  The investigator is required to maintain an accurate and complete record of all 
written correspondence to and received from the IRB or EC and must agree to share all such 
documents and reports with the Sponsor.
