Study Title:  
A Phase 2, Double-Blind, Randomized, Parallel-Group, Placebo-Controlled, Multi-Center 
Study to Evaluate the Efficacy, Safety, and Tolerability of Oral Omadacycline in Adult 
Subjects with Nontuberculous Mycobacterial (NTM) Pulmonary Disease Caused by 
Mycobacterium abscessus Complex (MABc) 
Study Number: 
PTK0796-NTM-20203 
Study Phase:  2 
Study Rationale: 
Omadacycline is an aminomethylcycline, a tetracycline class antibiotic, for intravenous or 
oral administration. Intravenous NUZYRA® (omadacycline) and oral NUZYRA tablets 
have been approved by the United States (US) Food and Drug Administration (FDA) for 
the treatment of adult patients with community-acquired bacterial pneumonia and acute 
bacterial skin and skin structure infections caused by susceptible microorganisms. 
More than 140 nontuberculous mycobacterial (NTM) species have been identified, with 
more than half of the NTM pulmonary infections in the US associated with Mycobacterium 
avium complex (MAC) (Prevots 2010; Spaulding 2017). Mycobacterium abscessus 
complex (MABc) is the second most common NTM grouping causing human disease in 
the US, comprising about 10% of all NTM pulmonary infections across various study sites 
(Prevots 2015). In 2010, the number of national cases of NTM pulmonary infections was 
estimated as 86,244 (Strollo 2015). More recently in 2019, the number of NTM pulmonary 
cases was estimated to be as high as 115,000 nationally (Insmed Presentation 2021). The 
annual prevalence of NTM pulmonary infections in the US in 2015 was estimated as 11.7 
per 100,000, representing a 7.5% annual increase from 2008 (Winthrop 2020).  
Infections caused by MABc are notoriously difficult to treat due to intrinsic resistance to 
many classes of antibiotics. Few oral antibiotics demonstrate in vitro activity against 
MABc, making long-term treatment extremely difficult. Currently there are no 
FDA-approved treatments for pulmonary disease caused by MABc. Current treatment 
options (off-label treatments) are typically lengthy and require complex, multi-drug

Study Design: 
This is a Phase 2, double-blind, randomized, placebo-controlled, parallel-group, multi-
center study in adults with NTM pulmonary disease caused by MABc. 
 
 
Following a Screening period of up to 56 days (8 weeks) prior to dosing, eligible subjects 
will be randomized (1.5:1) to receive either 300 mg once daily oral omadacycline 
monotherapy or matching placebo.  
Subjects will attend monthly visits during the approximately 84 day (3-month) 
double-blind treatment period and will complete a 14-day safety tele-visit as well as a 
safety follow-up call approximately 30 days after their last dose of test article.

Approximate Duration of the Study: 
Following an estimated recruitment period of approximately 24 months, the total duration 
of subject participation in the study is approximately 5 months which includes a total 
duration of study treatment for approximately 3 months (84 days). 
Study Population:  
Approximately 75 subjects (45 omadacycline and 30 placebo) will be enrolled at up to 
20 sites. Subjects will be randomized (1.5:1) to receive either omadacycline or placebo. 
Subjects will be stratified according to their use of prior antibiotics for treatment of MABc 
NTM infection (received prior treatment vs. no prior treatment). 
Main Criteria for Inclusion: 
Subjects must meet all of the following criteria at Screening and/or Baseline to be eligible 
to participate in the study: 
1. Written and signed informed consent must be obtained before any protocol-specific 
assessment is performed. 
2. Male and female subjects age 18 years or older. 
3. Diagnosed MABc pulmonary disease as per Infectious Diseases Society of 
America/American Thoracic Society guidelines criteria. Subjects must have: 
 At least 2 of the following NTM-infection symptoms at Screening and Baseline:  
 Chronic cough, coughing up blood (hemoptysis), wheezing, chest pain, frequent 
throat clearing, phlegm or sputum production, shortness of breath, fatigue, 
fever, night sweats, poor appetite, and/or weight loss. 
 At least 1 positive pulmonary culture for MABc in the 6 months prior to Screening, 
and 1 positive culture at Screening (note: prior culture and screening cultures must 
be at least 30 days apart). 
 Radiographic evidence of MABc infection via computed tomography (CT) scan of 
the chest within 3 months prior to Screening with findings consistent with NTM 
pulmonary disease. If no CT scan obtained within previous 3 months, one should 
be performed at Screening to confirm eligibility.  
4. Based on the clinical assessment of the investigator, guideline-directed antibiotic 
therapy for treatment of MABc will not be required within the next 3 months, and a 
delay, in order for the subject to participate in a placebo-controlled clinical trial, is 
considered reasonable and clinically acceptable.  
5. Be able to produce approximately 5 mL of sputum via spontaneous expectoration or be 
willing to undergo sputum induction to produce approximately 5 mL of sputum for 
microbiological evaluation.  
6. Females must have a negative serum pregnancy test and agree to use a highly effective 
form of birth control (eg, abstinence, oral contraceptive, intrauterine device, or barrier 
contraception [eg, condom], tubal ligation, hysterectomy, bilateral oophorectomy, 
postmenopausal or vasectomized partner) from Screening through study completion.

Efficacy Assessments: 
 Subject-reported NTM-pulmonary infection symptoms using a 4-point scale 
(absent, mild, moderate, severe)  
 Quantitative sputum culture 
 Patient-reported outcomes and quality of life measures: 
 QOL-B 
 SGRQ 
 PROMIS Short Form v1.0 – Fatigue 7a Daily 
 PGI-C 
 PGI-S 
 CGI-S 
 CGI-I 
 
Safety Assessments: 
Safety and tolerability will be assessed by monitoring the following: 
 AEs and SAEs 
 Physical examinations 
 Vital signs (body weight, body temperature, blood pressure, heart rate) 
 Laboratory tests (hematology and serum chemistry) 
 ECGs 
 CT scan 
 
Pharmacokinetic Assessments: 
Not applicable. 
 
STATISTICAL METHODS: 
A Statistical Analysis Plan (SAP) will be prepared and finalized before database lock and 
analyses of data. Summary data will be tabulated and presented by treatment group. 
Sample Size Determination:  
As the study is exploratory with respect to determination of efficacy, the sample size 
determination is provided to better ensure sufficient subjects are enrolled to provide an 
initial assessment of efficacy rather than test a specific hypothesis. With a randomization 
ratio of 1.5:1, a sample size of 75 subjects (45 omadacycline and 30 placebo) will provide 
approximately 80% power to detect an absolute treatment difference of 30% in clinical 
response rate at Day 84, based on clinical response rates of 15% and 45% in the placebo 
and omadacycline treatment groups respectively, using a Mantel-Haenszel test with 
2-sided alpha level of 0.05.

Analysis Sets:  
The following subject analysis sets have been defined: 
 Intent-to-treat (ITT) Analysis Set includes all randomized subjects. 
 Per-Protocol Analysis Set includes all randomized subjects who received at least 
1 dose of test article and completed the study without major protocol deviations 
that affect the assessment of efficacy. 
 Safety Analysis Set includes all subjects who received at least 1 dose of test article. 
 
Safety Assessments:   
All safety data will be analyzed in the Safety Analysis Set. Adverse events will be coded 
using the Medical Dictionary of Regulatory Activities. The incidence of 
treatment-emergent adverse events will be presented by system organ class (SOC) and 
preferred term (PT); by SOC, PT, and relationship to test article; and by SOC, PT, and 
severity. Serious AEs and treatment-emergent adverse events that lead to discontinuation 
of the test article will also be presented by SOC and PT. Descriptive statistics for clinical 
laboratory test results, vital signs, and ECG parameters, including change from baseline, 
will be presented by timepoint collected and for the overall most abnormal post-baseline 
value (for clinical laboratory results and vital signs). Incidences of potentially clinically 
significant clinical laboratory results, vital signs, and ECG parameters, as defined in the 
SAP, will also be summarized by timepoint collected and the overall most abnormal 
post-baseline value (for clinical laboratory results and vital signs). 
Efficacy Assessments: 
The study is exploratory with respect to efficacy determination. Efficacy will be evaluated 
based on endpoints defined by subject-reported NTM symptoms, subject-reported 
outcomes and quality of life measures, and microbiologic assessment. Additional 
endpoints to assess efficacy will be defined in the SAP. Nominal p-values are provided as 
descriptive statistics. 
Clinical response at Day 84 will be defined as (1) improvement in severity of at least 50% 
of symptoms present at baseline and (2) improvement in severity of at least 50% of 
symptoms present at baseline and no deterioration in severity of symptoms present at 
baseline. Subjects who receive alternative antibiotic therapy for treatment of the NTM 
infection, withdraw consent, and/or die before reaching Day 84 will be considered as not 
achieving clinical response. For both definitions, the number and percentage of subjects 
with a clinical response and no clinical response will be summarized by treatment group in 
the ITT Analysis Set. Exact 2-sided 95% confidence intervals for the point estimates of the 
clinical response rates in each treatment group will be determined using the 
Clopper-Pearson method. The odds ratio (omadacycline /placebo) and p-value will be 
calculated using Cochran-Mantel-Haenszel test, stratified by prior antibiotic use. 
Secondary efficacy endpoints based on patient-reported outcomes and quality of life 
assessments and microbiologic assessments will also be analyzed to provide supportive 
evidence of efficacy.

3 INTRODUCTION  
3.1 
Nontuberculous Mycobacterial Pulmonary Disease  
More than 140 nontuberculous mycobacterial (NTM) species have been identified, with more 
than half of the NTM pulmonary infections in the United States (US) associated with 
Mycobacterium avium complex (MAC) (Prevots 2010; Spaulding 2017). Mycobacterium 
abscessus complex (MABc) is the second most common NTM grouping causing human 
disease in the US, comprising about 10% of all NTM pulmonary infections across various 
study sites (Prevots 2015). In 2010, the number of national cases of NTM pulmonary 
infections was estimated as 86,244 (Strollo 2015). More recently in 2019, the number of 
NTM pulmonary cases was estimated to be as high as 115,000 nationally (Insmed 
Presentation 2021). The annual prevalence of NTM pulmonary infections in the US in 2015 
was estimated as 11.7 per 100,000, representing a 7.5% annual increase from 2008 
(Winthrop 2020).  
Infections caused by MABc are notoriously difficult to treat due to intrinsic resistance to 
many classes of antibiotics. Few oral antibiotics demonstrate in vitro activity against MABc, 
making long-term treatment extremely difficult. Currently there are no Food and Drug 
Administration (FDA)-approved treatments for pulmonary disease caused by MABc. Current 
treatment options (off-label treatments) are typically lengthy and require complex, multidrug 
regimens (Strnad 2018). M. abscessus isolates display in vitro resistance to most oral 
antibiotics and are generally susceptible to a limited number of parenteral agents. Previous 
guidelines recommend using a multidrug regimen including ≥ 2 of these antibiotics to which 
the organism is susceptible in vitro. Recent work suggests a lack of consensus among treating 
physicians, with a variety of regimens employed against this organism ranging from 2 to 5 
drugs in the initial phases of therapy (Daley 2020). 
Most of the antibiotics recommended for the treatment of MABc pulmonary infection have 
safety and tolerability profiles that are not conducive to an extended treatment course. 
Current treatment regimens are frequently associated with serious adverse effects and poor 
patient adherence contributing to poor clinical outcomes. With these current treatment 
challenges, expert NTM clinicians and patient advocacy groups have emphasized the urgent 
need for developing new antibiotics for the treatment of NTM infections. Ideally, these 
antibiotics would have potent in vitro activity and a high barrier to the emergence of 
resistance. A favorable safety and tolerability profile and the availability of an oral 
formulation both take on added importance because of the anticipated prolonged treatment 
duration. An antibiotic with these properties has the potential to improve both microbiologic 
and patient quality of life outcomes in patients with MABc pulmonary disease. 
Therefore, a clear unmet need exists for an effective and safe antibiotic that is well-tolerated 
and can be administered orally. Omadacycline has the potential to fill this unmet need. 
3.2 
Omadacycline  
The investigational product, omadacycline (formerly named PTK 0796), is the first member 
of the aminomethylcycline class of antibiotics, which are semisynthetic derivatives of the

tetracycline class. As a class, tetracyclines have been in use for approximately 70 years. They 
are well-tolerated and have proven effective in the treatment of a variety of bacterial 
infections. Intravenous NUZYRA (omadacycline) and oral NUZYRA tablets have been 
approved by the US FDA for the treatment of adult patients with community-acquired 
bacterial pneumonia (CABP) and acute bacterial skin and skin structure infections (ABSSSI) 
caused by susceptible microorganisms. 
While data from the completed nonclinical program supports dosing up to 90 days, this is the 
first clinical trial that will administer study dosing of omadacycline beyond 14 days of 
therapy. Current-use data indicate that omadacycline is being used for chronic dosing without 
any safety signal identified, through Paratek’s post-marketing pharmacovigilance program 
and published cases studies. Review of post-marketing off-label use reports did not reveal 
any trends or recommended updates to the current reference safety information. As of 
January 2021, 5 case series have been published that together report experience on 
19 patients with NTM infections, predominately M. abscesses (Frizzell 2020; Gill 2019; 
Minhas 2019; Morrisette 2021; Pearson 2020). Patients were treated with oral omadacycline 
for periods ranging from 4 weeks to 20.6 months, all but one as part of a multidrug regimen. 
Omadacycline was overall safe and well-tolerated. Clinical success was reported in 
16 patients. Reported events were consistent with the established safety profile and are not 
unexpected. These real-world observational reports of treatment with omadacycline for NTM 
provide support to progress to a randomized controlled trial setting, including long-term 
dosing. 
Please refer to the current version of the Investigator’s Brochure for additional information 
on omadacycline. 
3.3 
Properties of Omadacycline that Address the Unmet Treatment Need for 
M. abscessus Complex Pulmonary Infection  
Omadacycline has several key characteristics that may prove beneficial to patients with 
MABc pulmonary infection: 
 Potent in vitro activity versus M. abscessus complex subspecies  
 No antagonism in vitro when tested in combination with other antimicrobials 
commonly used to treat M. abscessus infections 
 Demonstrated efficacy in a mouse model of M. abscessus pulmonary infection 
 Favorable pharmacokinetics (PK) and dosing regimen  
 Extensive penetration into lung tissue compartments including epithelial lining 
fluid and alveolar macrophages  
 Half-life of 17 hours supports once-daily dosing  
 No dosing adjustments are required for age, weight, race, sex, renal or hepatic 
impairment   
 Established safety profile in pre-clinical studies and Phase 3 clinical trials conducted 
in CABP and ABSSSI populations (up to 14 days of dosing) 
 Does not prolong the QTc interval

5 INVESTIGATIONAL PLAN  
5.1 
Overall Study Description  
This is a Phase 2, double-blind, randomized, placebo-controlled, parallel-group, multi-center 
study in adults with NTM pulmonary disease caused by MABc. The study design is shown in 
Figure 1. 
Figure 1. Study Design Schema 
 
 
 
Following a Screening period of up to 56 days (8 weeks) prior to dosing, eligible subjects 
will be randomized (1.5:1) to receive either 300 mg once daily oral omadacycline 
monotherapy or matching placebo. Subjects will be stratified according to their use of prior 
antibiotics for treatment of MABc NTM infection (received prior treatment vs. no prior 
treatment). 
Subjects will attend monthly visits during the approximately 84 day (3-month) double-blind 
treatment period. In addition, subjects will complete a 14-day safety tele-visit as well as a 
safety follow-up call approximately 30 days after their last dose of test article. Total duration 
of subject participation is approximately 5 months.  
Refer to the Schedule of Assessments for a complete summary of subject visits and 
assessments.  
5.2 
Rationale for Study Design  
This study is intended to assess the safety and efficacy of omadacycline in addition to non-
pharmacologic standard of care in NTM subjects caused by MABc. Non-pharmacologic 
measures, including patient education, airway clearance technique, inspiratory muscle 
training, and exercise training, are considered the first line of therapy in these subjects and 
will be permitted during the study (Lan 2020). A 3-month, monotherapy, placebo-controlled 
study design will allow the best assessment of omadacycline without any confounding

6 STUDY POPULATION SELECTION  
Each subject must participate in the informed consent process and sign and date an 
IRB/IEC/REB-approved informed consent form (ICF) before any procedures specified in this 
protocol are performed. 
6.1 
Study Population  
This study will evaluate adult subjects with NTM pulmonary disease caused by MABc.  
6.2 
Inclusion Criteria  
Subjects must meet all of the following criteria at Screening and/or Baseline to be eligible to 
participate in the study: 
1. Written and signed informed consent must be obtained before any protocol-specific 
assessment is performed. 
2. Male and female subjects age 18 years or older. 
3. Diagnosed MABc pulmonary disease as per Infectious Diseases Society of 
America/American Thoracic Society guidelines criteria. Subjects must have: 
 At least 2 of the following NTM-infection symptoms at Screening and Baseline:  
 Chronic cough, coughing up blood (hemoptysis), wheezing, chest pain, frequent 
throat clearing, phlegm or sputum production, shortness of breath, fatigue, fever, 
night sweats, poor appetite, and/or weight loss 
 At least 1 positive pulmonary culture for MABc in the 6 months prior to Screening 
and 1 positive culture at Screening (note: prior culture and screening cultures must be 
at least 30 days apart). 
 Radiographic evidence of MABc infection via computed tomography (CT) scan of 
the chest within 3 months prior to Screening with findings consistent with NTM 
pulmonary disease. If no CT scan obtained within previous 3 months, one should be 
performed at Screening to confirm eligibility.  
4. Based on the clinical assessment of the investigator, guideline-directed antibiotic therapy 
for treatment of MABc will not be required within the next 3 months, and a delay, in 
order for the subject to participate in a placebo-controlled clinical trial, is considered 
reasonable and clinically acceptable.  
5. Be able to produce approximately 5 mL of sputum via spontaneous expectoration or be 
willing to undergo sputum induction to produce approximately 5 mL of sputum for 
microbiological evaluation. 
6. Females must have a negative serum pregnancy test and agree to use a highly effective 
form of birth control (eg, abstinence, oral contraceptive, intrauterine device, or barrier 
contraception [eg, condom], tubal ligation, hysterectomy, bilateral oophorectomy, 
postmenopausal or vasectomized partner) from Screening through study completion. 
Males (if sexually active) must agree to use a highly effective method of birth control 
with female partner(s) from Screening through study completion.

Screen Failures  
Subjects who sign the ICF but withdraw or are withdrawn from the study before random 
assignment to double-blind treatment are defined as screen failures. All screen failures 
should be recorded on the subject master list. Limited information including reason for 
screen failure will be recorded on the electronic case report form (eCRF) or interactive 
voice/web response system (IxRS) system for screen failures. Screen failure subjects may be 
re-screened at the discretion of the investigator and in consultation with the medical monitor 
as needed. Any subject who discontinues participation or is withdrawn before receiving a 
treatment assignment, and who is re-screened at a later time will be assigned a new subject 
number and recorded as re-screened.

7.3 
Dose Selection Rationale  
The dosing regimen of omadacycline selected for this study is based on the demonstration of 
efficacy in a mouse model of M. abscessus pulmonary infection, as well as the totality of 
nonclinical and clinical experience to date, including in vitro antibacterial activity, PK 
characteristics, and the overall safety and tolerability profile of the FDA-approved dosing 
regimens for treatment of CABP and ABSSSI. 
In a nonclinical C3HeB/FeJ mouse model of M. abscessus pulmonary infection, 
omadacycline efficacy was demonstrated using the dose best representing the human 
equivalent exposure ie, area under the concentration-time curve (AUC) of the human 300 mg 
oral dose. The C3HeB/FeJ mouse was previously demonstrated to provide utility as a mouse 
model of M. abscessus pulmonary infection for antibacterial studies (Maggioncalda 2020; 
Story-Roller 2019). Administration of a corticosteroid (dexamethasone) allows for initial 
proliferation of and subsequent sustained M. abscessus pulmonary infection and pathology 
following infection via an aerosolized route. 
As detailed in the Investigator’s Brochure, the steady state AUC (hr*µg/mL) for the 300 mg 
oral dose is 11.156, while the steady state free AUC (hr*µg/mL) of the 300 mg oral dose is 
8.92 (adjustment for free fraction by 20% human plasma protein binding; on file at Paratek). 
Therefore, a mouse dose was selected to represent a steady state free AUC (hr*µg/mL) of 
approximately 9. 
Omadacycline PK parameters in C3HeB/FeJ mice were determined after subcutaneous 
administration of omadacycline doses of 7.5, 15 and 30 mg/kg in order to calculate the 
appropriate mouse dose to study in the efficacy model. Following determination of key PK 
parameters, adjustment for free fraction in mice (33.9% mouse plasma protein binding; data 
on file at Paratek), and graphical assessment of the mouse free area under the concentration-
time curve from time zero to 24 hours (AUC0-24) (hr*µg/mL) versus mouse doses studied, the 
resulting linear equation was utilized to calculate the appropriate mouse dose. Specifically, 
the data demonstrated that a mouse subcutaneous dose of approximately 15 mg/kg every 
24 hours (q24h) best represents a human AUC0-24 (hr* µg/mL) of 9 (on file at Paratek). 
The American Type Culture Collection (ATCC) reference strain M. abscessus 19977 
(omadacycline minimum inhibitory concentration [MIC] values of 0.25 to 0.5 µg/mL) and 
the clinical isolate M9501 (omadacycline MIC value of 0.25 µg/mL) were evaluated in the 
mouse model of efficacy (MIC data on file at Paratek). Mice were infected via aerosolization 
and treatment was initiated 1-week post-infection. Mice were treated with either 
omadacycline (15 mg/kg q24h), imipenem (200 mg/kg every 12 hours; positive control) or 
vehicle (phosphate buffered saline; q24h) for 4 weeks and the bacterial burden in the lungs 
was evaluated at various timepoints (0, 1 week, 2 weeks, and 4 weeks) throughout the study. 
Efficacy was determined as a reduction in lung bacterial burden compared to vehicle 
controls. 
M. abscessus lung burden in the vehicle control group increased throughout the course of 
infection as expected. In the positive control group (imipenem treatment), M. abscessus lung 
burden decreased gradually over the duration of the study. For mice infected with the 

Omadacycline

reference strain ATCC 19977, at the final timepoint of 4 weeks of treatment, omadacycline 
produced >3 log10 reduction in total lung colony forming units compared to mice in the 
vehicle control group. Similarly, omadacycline treatment reduced lung burden of the clinical 
strain M9501 by 2 log10 at the conclusion of 4 weeks of treatment.  
Therefore, based on the demonstration of omadacycline efficacy in the mouse model of M. 
abscessus pulmonary infection at the equivalent human steady state free AUC (hr*µg/mL) of 
approximately 9, the 300 mg oral dose will be evaluated in this human clinical study. 
Phase 3 clinical trials in CABP and ABSSSI have demonstrated that omadacycline has an 
acceptable safety profile. Additionally, the 300 mg oral dose being used in this study has 
been approved by the FDA for these indications.

or drink (except water) is permitted for 2 hours and no dairy products, antacids or 
multivitamins containing multivalent cations (eg, aluminum, magnesium, calcium, bismuth, 
iron, or zinc) for 4 hours. 
7.6 
Dose Adjustments and Interruptions of Test Article  
No dose adjustments or planned interruptions of test article will be permitted during this 
study. 
7.7 
Method of Assigning Patients to Treatment Groups  
All eligible subjects will be randomized via an IxRS that assigns them to the treatment group 
in a 1.5 to 1 ratio (omadacycline: placebo). The site delegate will contact the IxRS after 
confirming that the subject fulfills all the inclusion criteria and has none of the exclusion 
criteria. The IxRS will assign a test article to the subject based on a computer-generated

randomization schedule. The randomization will be a blocked randomization sequence 
stratified by prior antibiotic use for treatment of MABc NTM infection (prior antibiotic use 
and no prior antibiotic use) as defined in the IxRS specifications. Subjects randomized into 
the study will be assigned the treatment corresponding to the next available number from the 
computer-generated randomization schedule. The subject is considered randomized when the 
IxRS provides the test article assignment, regardless of whether the subject actually receives 
any test article. 
7.7.1 
Subject Numbering  
Upon the subject signing the informed consent, site personnel should enter the subject in the 
IxRS, and the subject will be assigned a unique subject number. Subjects who have been 
pre-screened but who do not sign an ICF will not be assigned a subject number. A subject 
who discontinues participation or is withdrawn before receiving a treatment assignment, and 
who is re-screened at a later time will be assigned a new subject number and recorded as 
re-screened. Re-screening is at the discretion of the investigator and in consultation with the 
medical monitor. The investigator will maintain a subject master list to document every 
subject who has signed an ICF using the subject number assigned by the IxRS. A copy of this 
list should be retained in the investigator’s study files.  
7.8 
Dispensing Test Article  
Each study site will be supplied by the sponsor with the test article. Oral test article supplies 
are completely blinded, and blinded study personnel can conduct storage, dispensation, and 
reconciliation. The IxRS will assign the test article kit to be given to the subject. 
Oral test article will be supplied to the sites in labelled, blinded kits that contain 6 blister 
cards (12 tablets per card, 72 tablets per kit) of omadacycline (150 mg) tablets or matching 
placebo tablets. Each kit contains enough test article for 4 weeks of test article administration 
between visits. At each visit when test article is dispensed (Baseline, Day 28, Day 56), study 
personnel will access the IxRS and be assigned a test article kit to be given to the subject. 
The study coordinator/staff will instruct the subject on the use of oral test article. 
7.9 
Blinding  
The investigator and sponsor will be blinded to treatment group assignments throughout the 
study. The sponsor designee (eg, clinical supply manager, IxRS vendor, etc.) will have a 
designated randomization administrator who will maintain the randomization codes in 
accordance with standard operating procedures to ensure the blind is properly maintained and 
that only sponsor personnel who require knowledge of treatment assignments will be 
unblinded (eg, staff involved in maintaining the randomization codes). 
Randomization data are kept strictly confidential until the time of database lock and 
unblinding at the end of the study. Unblinded treatment assignments will be provided to 
study sites after the study has concluded.

Page 32 of 68 
All test articles will be supplied in identical packaging thereby maintaining the blinding for 
all site staff and subjects. 
Unblinding by site personnel is only to occur in the case of subject emergencies (see 
Section 7.10, below).  
7.10 Emergency Unblinding of Treatment Assignment  
Emergency unblinding should only be undertaken when it is essential to treat the subject 
safely and efficaciously. Most often, test article discontinuation and knowledge of the 
possible treatment assignments are sufficient to treat a study subject who presents with an 
emergency condition. It is encouraged for the investigator, when contemplating unblinding, 
to contact the sponsor or sponsor’s designated medical monitor or designee to confirm the 
need to unblind, prior to unblinding (see Section 2 for contact information). However, if 
required, the investigator can unblind without consulting the medical monitor. 
Emergency code breaks are performed using the IxRS. When the investigator contacts the 
system to unblind a subject, he/she must provide the requested subject identifying 
information and confirm the necessity to unblind the subject. The investigator will then 
receive details of the drug treatment for the specified subject and a fax or e-mail confirming 
that the treatment assignment of the subject was unblinded. The system will automatically 
inform the sponsor’s monitor and the sponsor that the code has been broken. 
It is the investigator’s responsibility to ensure that there is a procedure in place at their site to 
allow access to the IxRS code break information in case of emergency. The investigator will 
inform the subject how to contact his/her backup in cases of emergency when he/she is 
unavailable. 
All steps outlined above will be followed, including contacting the medical monitor as soon 
as possible and not more than 24 hours afterwards. It will be the responsibility of all study 
personnel to ensure that, except for the above procedure, investigator blinding is maintained 
until after study completion. 
7.11 Prior and Concomitant Therapy  
 All antibiotics administered for the subject’s MABc or MAC infection within 2 years 
prior to the date of informed consent will be recorded in the eCRF. 
 All significant non-pharmacological therapies related to MABc infection including 
patient education, airway clearance technique, inspiratory muscle training, and 
exercise training administered from 30 days prior to date of informed consent, and 
administered throughout the duration of the study through the 30-day follow-up 
period, will be recorded in the eCRF. 
 All pharmacological therapies (regardless of indication) that have been administered 
from 7 days prior to the date of informed consent and administered throughout the 
duration of the study through the 30-day follow-up period, will be recorded in the 
eCRF.

 All significant non-pharmacological therapies not related to MABc infection 
administered from 7 days prior to date of informed consent, and administered 
throughout the duration of the study through the 30-day follow-up period, will be 
recorded in the eCRF. 
 
7.12 Prohibited Therapy  
The following therapies (including timeframe for exclusion) are prohibited: 
 Antibiotic treatment for MABc or MAC infection (including systemic or inhaled 
antibiotics) within 6 months prior to Screening and through Day 84/end of treatment 
(EOT) visit 
 Systemic or inhaled antibiotic therapy (other than chronic macrolide therapy) within 
4 weeks prior to Screening and through Day 84/EOT visit 
 Systemic treatment with disease-modifying antirheumatic agents, corticosteroids 
(equivalent to prednisone dose ≥ 15 mg/day for a period of ≥ consecutive 4 weeks 
above this level) or immunosuppressive agents within 90 days prior to Screening and 
through Day 84/EOT visit 
 Use of isotretinoin within 2 weeks prior to Screening and through Day 84/EOT visit 
 Subjects will be instructed to avoid taking antacids and multivitamins containing 
multivalent cations (eg, aluminum, magnesium, calcium, bismuth, iron, or zinc) for 
4 hours before and within 4 hours after oral doses  
 
7.13 Permitted Treatments  
All other treatments not specified as prohibited are permitted during the study. Subjects 
requiring additional or alternative therapy for their MABc NTM pulmonary disease will be 
discontinued from test article. Further treatment for their infection is at the discretion of the 
investigator or the subject’s health care provider and will be considered as a concomitant 
medication. 
Subjects should be encouraged to contact site personnel before starting any new treatment. 
7.14 Treatment Compliance  
Subjects will record daily test article dosing information in a paper diary. Study personnel at 
the site should monitor oral test article compliance at each study visit by comparing the 
returned test article with the dosing information reported by the subject. Compliance and any 
unresolved discrepancies will be documented in the source document and on the drug 
inventory record. The test article eCRF should reflect the reconciled dosing information 
provided by the subject.

7.15 Packaging and Labeling  
The investigational test article, omadacycline, and the placebo will be packaged by the 
sponsor and supplied to the investigator.  
7.16 Storage and Accountability  
Test article must be received at the study site by a designated person, acknowledged in the 
IxRS, handled and stored safely and properly, and kept in a secured location to which only 
the investigator and designated staff have access. Upon receipt, the test article should be 
stored according to the instructions specified on the drug labels. Storage conditions must be 
adequately monitored, and appropriate temperature logs maintained as source data. 
The designated study personnel must maintain an accurate record of the shipment and 
dispensing of test articles. Test article supplies are completely blinded. Subjects will be asked 
to return all unused test article and packaging at each visit and at the end of the study, last 
study visit or at the time of test article discontinuation. Monitoring of oral test article 
accountability will be performed by the field monitor during site visits and at the completion 
of the study. 
7.17 Investigational Product Retention at Study Site  
At the conclusion of the study, and as appropriate during the course of the study, with 
instruction and approval from the sponsor, the designated study personnel will destroy on site 
as permitted by local site operating procedures, or return all unused test articles, packaging, 
and drug labels. Test articles can only be returned or destroyed after the sponsor has 
performed accountability. Destruction/return of all test article will be documented and 
maintained in the site files.

8 STUDY PROCEDURES  
Written, signed, and dated informed consent will be obtained before any study-related 
procedures have been performed. Upon signing the informed consent, the subject will be 
assigned a study subject number. Subjects who have been pre-screened but who do not sign 
an ICF will not be assigned a subject number. The investigator will maintain a subject master 
list to document every subject who has signed an ICF using the subject number assigned by 
the IxRS. A copy of this list should be retained in the investigator’s study files.  
A study Schedule of Assessments is provided in Appendix 1. 
8.1 
Informed Consent  
The investigator will provide for the protection of the subjects by following all applicable 
regulations. These regulations are available upon request from the sponsor. The ICF must be 
reviewed by the sponsor and approved by the IRB/IEC/REB. 
Before any procedures specified in the protocol are performed, a subject must: 
 Be informed of all pertinent aspects of the study and all elements of informed consent  
 Be given time to ask questions and time to consider the decision to participate 
 Voluntarily agree to participate in the study 
 Sign and date an IRB/IEC/REB-approved ICF 
 
Subjects will also have the option to provide consent for collection of serum and plasma for 
biomarkers. This is not required for subject eligibility and participation (See Section 8.11). 
8.2 
Subject Demographics/Other Baseline Characteristics  
Subject demographic and baseline characteristic data to be collected on all subjects include 
date of birth (per local regulations), gender, and race/ethnicity. 
8.3 
Medical History  
The investigator will perform a comprehensive history at the Screening visit. Significant 
medical history (at any time) and any medical history within the past 6 months including 
ongoing medical conditions at the time of signing of the ICF will be recorded. 
Where possible, diagnoses are to be recorded. Any event or change in the subject’s condition 
or health status occurring after signing the ICF will be reported as an AE. 
8.4 
Physical Examination  
At Screening and Day 84/EOT, a full physical examination will include the examination of 
general appearance, skin, neck (including thyroid), eyes, ears, nose, throat, lungs, heart, 
abdomen, back, lymph nodes, extremities, and vascular and neurological systems.

Page 36 of 68 
Information for all physical examinations must be included in the source documentation at 
the study site. Relevant findings that are present prior to the start of test article must be 
included in the relevant medical history/current medical conditions screen on the subject’s 
eCRF. New clinically significant findings made after the start of test article which meet the 
definition of an AE must be recorded as an AE in the subject’s eCRF. 
8.5 
Vital Signs  
Vital signs including blood pressure, heart rate, body temperature, and pulse oximetry will be 
measured at the timepoints as specified in Appendix 1. 
The subject’s vital signs should be captured after at least 5 minutes (+ 5 minutes) of rest 
while in a non-standing position (supine or sitting). Subsequent vital sign measurements 
should be captured in the same non-standing position. 
8.6 
Height, Weight and Body Mass Index  
Height and body weight should be obtained with the subject’s shoes off and recorded in the 
eCRF at the timepoints as specified in Appendix 1. Body mass index will be automatically 
calculated upon entry of height and weight in the eCRF. 
8.7 
Electrocardiogram  
A standard 12-lead ECG should be obtained using site equipment. The ECG will be obtained 
after the subject has been in a semi-recumbent position for approximately 10 minutes at the 
Screening and Day 84/EOT Visit. Reading and interpretation of the ECG will be performed 
locally by the investigator, and hard copies of the reports retained in the files. 
8.8 
Computed Tomography Scan – Chest  
Computed tomography scans of the chest will be performed using site equipment or local 
radiology facility. High resolution CT scan is preferred, if available. The CT scan will be 
interpreted by appropriately qualified personnel who are certified or licensed to interpret 
chest radiographs according to applicable regional requirements, reviewed by the investigator 
or qualified personnel and the conclusions of this review will be the basis for subject 
inclusion. The review report should be included in the source documents. 
Sites may utilize results of a chest CT scan performed within 3 months prior to Screening to 
determine eligibility (radiographic evidence of MABc infection). If no CT scan was obtained 
within the 3 months prior to Screening, a CT scan will be required at Screening. A follow-up 
chest CT scan will also be performed at the Day 84/EOT visit.

Local Safety Laboratory Parameters  
All female subjects will have a local urine or serum pregnancy test at the site during 
Screening and at the Baseline Visit (just prior to randomization). Urine pregnancy test kits 
will be provided by the sponsor through the Central Laboratory. If a positive urine or serum 
pregnancy test result is obtained at the site during Screening or at the Baseline Visit, the 
subject is not to be randomized. 
A serum sample for serum β-human chorionic gonadotropin (β-hCG) testing will be collected 
and sent to the Central Laboratory for confirmation of the local urine or serum pregnancy test 
results. If a positive β-hCG result is reported by the Central Laboratory after a subject is 
enrolled, test article administration should be discontinued.

8.10 Sputum Collection For Microbiology  
A Central Specialty Microbiology Laboratory will be used for analysis of all sputum 
specimens. Details on the collection supplies, shipment of samples and reporting of results 
are provided to investigators in the Central Laboratory Manual.  
Pre-dose expectorated or induced sputum specimens (approximately 5 mL) will be collected 
at all timepoints as indicated in Appendix 1. To improve the probability of obtaining a good 
sputum specimen, at least 2 and preferably 3 spontaneously expectorated sputum samples 
will be obtained from subjects at each timepoint. During Screening, samples will be collected 
after the subject signs the informed consent. For all subsequent visits, sputum samples should 
be collected on 2 to 3 consecutive days (when possible), just prior to, and up through the day 
of the scheduled visit.  
If a subject is unable to produce sputum spontaneously and independently, sputum induction 
may be performed by appropriately qualified site staff to obtain one induced sputum 
specimen. Please refer to Appendix 3. If a subject is still unable to produce sputum despite 
reasonable efforts at any visit post-Baseline, this will be considered as a negative culture 
result at that timepoint. Sterile, leak proof, non-wax, disposable plastic containers will be 
used to collect specimens. Detailed instructions will be provided by site staff to subjects on 
how to collect and handle samples aseptically to avoid contamination. Subjects will also be 
instructed to keep sputum samples refrigerated, not frozen, until ready to transport to the site. 
Upon receipt at the site, samples should be kept refrigerated until ready to ship to the central 
specialty microbiology lab. Shipping should occur within approximately 2 days of receipt 
from subject to avoid overgrowth by contaminating normal flora. No fixative or preservatives 
are to be used with sputum samples. Detailed instructions for collecting, processing, and 
shipping sputum specimens will be provided in the Central Laboratory Manual. 
The Central Specialty Microbiology Lab will process the sputum specimens. Acid fast bacilli 
smear testing from sputum will be performed on all specimens received. Specimens will be 
further cultured in both solid and liquid media and identification of genus and species will be 
performed, to the subspecies level for M. abscessus. Results confirming M. abscessus 
infection will be used to verify subject eligibility during Screening. 
In vitro susceptibility testing of antimicrobial drugs that may be used to treat M. abscessus 
pulmonary infection will be performed, and molecular characterization for select drug 
resistance markers will be performed. Susceptibility results will not be reported to site 
personnel during the study. 
8.11 Serum and Plasma Collection for Biomarkers (optional)  
Serum and plasma for biomarkers will be collected and stored at a central laboratory for 
future use for all subjects who provide consent for this optional portion of the study.  
Samples may be stored for a period of up to 2 years after the completion (termination) of the 
study, or longer, to see if there may be indicators associated with NTM lung infections and

for other exploratory analyses. Genetic testing or analysis will not be performed on any 
samples collected.  
8.12 NTM Symptom Assessment Questionnaire  
The NTM Symptom Assessment Questionnaire is a tool created by Paratek to evaluate 
efficacy based on individual subject assessment of symptoms. It is a self-administered 
questionnaire that evaluates a list of 12 common NTM symptoms, asking subjects if they 
have experienced each symptom within the past 7 days. Responses are provided using a 
4-point scale (absent, mild, moderate, severe) and should reflect the subject’s perceived 
overall impression of their symptoms over the past 7 days. This questionnaire is completed 
by the subject without interpretation of the subject’s response by a clinician or site staff. 
In addition, at Screening, subjects will be asked to list up to 3 of their most bothersome 
symptoms.  
The NTM Symptom Assessment Questionnaire will be completed at Screening, 
Baseline/Day 1 (prior to first dose of test article), and the Day 28, Day 56, and Day 84/EOT 
Visits. Responses at Screening and Baseline/Day 1 will be used to determine eligibility. 
8.13 Other Patient-Reported Outcomes and Clinician-Assessed Outcomes  
Patient-reported outcomes are being utilized in this study to help understand and assess the 
subject’s health, quality of life or functional status associated with the disease under study 
and treatment received. The PROs are completed by the subject without interpretation of the 
subject’s response by a clinician or site staff but should be reviewed for completeness and to 
assess potential AE information. 
All PROs described below will be completed the Day 28, Day 56, and Day 84/EOT visits. In 
addition, the QOL-B, SGRQ, and PROMIS Fatigue will be collected at Day 1/Baseline visit 
(prior to first dose of test article). 
8.13.1 
Quality of Life – Bronchiectasis  
The QOL-B is a self-administered, patient-reported outcome measure assessing symptoms, 
functioning and health-related quality of life for patients with non-cystic fibrosis 
bronchiectasis using a series of 37 questions.  
8.13.2 
St. Georges Respiratory Questionnaire  
The SGRQ is a self-administered questionnaire that assesses health-related quality of life in 
subjects with chronic pulmonary disease by evaluating 3 health domains:  
 symptoms (distress caused by respiratory symptoms) 
 activity (effects of disturbances to mobility and physical activity) 
 impacts (the effect of disease on factors such as employment, personal control of 
one’s health, and need for medication)

8.13.3 
Patient-Reported Outcomes Measurement Information System Short Form 
v1.0 – Fatigue 7a Daily  
The PROMIS Fatigue is a self-administered questionnaire that assesses fatigue and its impact 
on physical, mental, and social activities. The fatigue short form is universal rather than 
disease-specific and assesses fatigue over the past 7 days. 
8.13.4 
Patient Clinical Impression of Severity  
The PGI-S is a self-administered, single question assessed using a 7-point scale that measures 
a subject’s perception of disease severity. 
8.13.5 
Patient Clinical Impression of Change  
The PGI-C is a self-administered, single question assessed using a 7-point scale that 
measures a subject’s perceived change in clinical status and overall improvement. 
8.13.6 
Clinical Global Impression – Severity of Illness  
The CGI-S is administered by an experienced clinician who is familiar with the disease under 
study. The CGI-S is a 1-item observer-rated scale that rates illness severity based upon 
observed and reported symptoms, behavior, and function over the past seven days. 
8.13.7 
Clinical Global Impression – Improvement  
The CGI-I is administered by an experienced clinician who is familiar with the disease under 
study and who can make an expert judgment about the total picture of the subject at each 
visit. The CGI-I is a 1-item observer-rated scale that rates total subject improvement 
compared to baseline and whether or not, per clinical judgment, it is due entirely to drug 
treatment.  
8.14 Adverse Events  
An AE is any untoward, undesired, or unplanned event in the form of signs, symptoms, 
disease, or laboratory or physiologic observations occurring in a person given a test article or 
in a clinical study. The event does not need to be causally related to the test article or clinical 
study. An AE includes, but is not limited to, the following: 
 Any clinically significant worsening of a preexisting condition. 
 An AE occurring from overdose of a test article, whether accidental or intentional. 
Overdose is a dose greater than that specified in the protocol. 
 An AE occurring from abuse (eg, use for nonclinical reasons) of a test article. 
 An AE that has been associated with the discontinuation of the use of a test article.

8.15 Serious Adverse Events  
An SAE is an AE that: 
 Results in death. 
 Is life-threatening (see below). 
 Requires hospitalization or prolongation of an existing hospitalization (see below). 
 Results in a persistent or significant disability or incapacity (see below). 
 Results in a congenital anomaly or birth defect. 
 Additionally, important medical events that may not result in death, be 
life-threatening, or require hospitalization may be considered SAEs when, based on 
appropriate medical judgment, the event may jeopardize the subject and may require 
medical or surgical intervention to prevent any one of the outcomes listed above in 
this definition. Examples of such events include allergic bronchospasm requiring 
intensive treatment in an emergency room or at home, blood dyscrasias or 
convulsions that do not result in hospitalization, or development of drug dependency 
or drug abuse. 
 
An AE is considered “life-threatening” if, in the view of the investigator or sponsor, its 
occurrence places the subject at immediate risk of death. It does not include an AE that, had 
it occurred in a more severe form, might have caused death. For example, hepatitis that 
resolved without evidence of hepatic failure would not be considered life-threatening, even 
though hepatitis of a more severe nature can be fatal. Similarly, an allergic reaction resulting 
in angioedema of the face would not be life-threatening, even though angioedema of the 
larynx, allergic bronchospasm, or anaphylaxis can be fatal. 
Hospitalization is official admission to a hospital. Hospitalization or prolongation of a 
hospitalization constitutes criteria for an AE to be serious; however, it is not in itself 
considered an SAE. In the absence of an AE, a hospitalization or prolongation of a 
hospitalization should not be reported as an SAE by the participating investigator. This is the 
case in the following situations: 
 The hospitalization or prolongation of hospitalization is needed for a procedure 
required by the protocol. 
 The hospitalization or prolongation of hospitalization is part of a routine procedure 
followed by the center (eg, stent removal after surgery). This should be recorded in 
the study file. 
 A hospitalization for a preexisting condition that has not worsened.  
 
Disability is defined as a substantial disruption in a person’s ability to conduct normal life 
functions. 
If there is any doubt about whether the information constitutes an SAE, the information is 
treated as an SAE.

8.16 Other Reportable Information  
Certain information, although not considered an SAE, must be recorded, reported, and 
followed up as indicated for an SAE. This includes: 
 Pregnancy exposure to a test article:  If a pregnancy is confirmed, use of the test 
article must be discontinued immediately. Information about pregnancy exposure 
includes the entire course of pregnancy and delivery, and perinatal and neonatal 
outcomes, even if there are no abnormal findings. Both maternal and paternal 
exposures are considered other reportable information. For exposure involving the 
female partner of a male subject, the necessary information must be collected from 
the subject, while respecting the confidentiality of the partner. 
 Lactation exposure to a test article with or without an AE. 
 Overdose of a test article as specified in this protocol with or without an AE. 
 Inadvertent or accidental exposure to a test article with or without an AE. 
 
8.17 Overdose  
Any administration of omadacycline of greater than 600 mg within a 24-hour period will be 
an overdose, regardless of whether the overdose is intentional or accidental. It is a reportable 
event and the sponsor must be notified within 1 business day. 
The physician managing the overdose may order any test he/she thinks is necessary to 
manage the subject properly. 
8.18 Medication Errors  
Medication errors are the result of administration or consumption of the wrong product, by 
the wrong subject, at the wrong time, and/or by the wrong administration route, due to human 
error. 
Medication errors include, but are not limited to, the following: 
 The administration and/or consumption of test article that has not been assigned to the 
subject 
 Administration of expired test article 
 
All AEs and SAEs must be handled as specified in this protocol whether or not they are 
associated with a medication error. A medication error associated with an SAE (including 
overdose, inadvertent exposure, and/or accidental exposure) will be reported with the SAE on 
the SAE Report Form. All other medication errors will be reported by e-mailing the Clinical 
Test Article Error Incident Report Form to clinicalsafety@propharmagroup.com.

8.19 Recording and Reporting  
A subject’s AEs and SAEs will be recorded and reported from the signing of the ICF to the 
time of the Follow-up assessment. The investigator must instruct the subject to report AEs 
and SAEs during this time period. Reports of death after the last study contact with the 
subject will be reported to the sponsor and additional information relative to the cause of 
death will be sought and documented. 
All AEs and SAEs must be recorded on source documents. All AEs and SAEs for subjects 
who receive a treatment assignment will be recorded in the eCRFs. 
The investigator must follow up as medically necessary on all AEs and SAEs until the events 
have subsided, the condition has returned to Baseline, or in case of permanent impairment, 
until the condition stabilizes. 
Adverse events should be based on the signs or symptoms detected during the physical 
examination and on clinical evaluation of the subject. In addition to the information obtained 
from those sources, the subject should be asked the following nonspecific question:  “How 
have you been feeling since your last visit?” Whenever possible, AEs should be reported as a 
diagnosis rather than individual signs and symptoms. If a definitive diagnosis is not possible, 
the individual signs and symptoms should be recorded using standard medical terminology. 
If an AE requires a surgical or diagnostic procedure, the illness leading to the procedure 
should be recorded as the AE, not the procedure itself. 
Death should be recorded in the eCRF as an outcome of an AE. Any unanticipated risks to 
the subjects must be reported promptly to the IRB/IEC/REB.  
8.19.1 
Serious Adverse Event Reporting  
All SAEs and follow-up information must be reported within 1 business day or 24 hours as 
required by local regulations by emailing a completed SAE Report to the email address 
below.  
E-Mail: 
8.19.2 
Assessment of Relatedness  
The investigator will assess causality (ie, whether there is a reasonable possibility that test 
article caused the event) for all AEs and SAEs. The relationship will be characterized using 
the following classification: 
 Not Related:  This relationship suggests that there is no association between test 
article and the reported event. The event can be explained by other factors such as an 
underlying medical condition, concomitant therapy, or accident, and no plausible 
temporal or biologic relationship exists between test article and the event. 
 Related:  This relationship suggests that a definite causal relationship exists between 
test article administration and the AE, or there is a reasonable possibility that the

Page 44 of 68 
event was caused by the test article, and other conditions (concurrent illness, 
progression/expression of disease state, or concurrent medication reaction) do not 
appear to explain the event. 
Adverse events and SAEs also will be assessed for their potential relationship to the protocol. 
A protocol-related AE is one that is not related to the test article but is considered by the 
investigator or the medical monitor (or designee) to be related to the research conditions, ie, 
related to the fact that a subject is participating in the study. For example, a protocol-related 
AE may be an untoward event related to a medical procedure required by the protocol. 
8.19.3 
Assessment of Severity  
The severity (or intensity) of an AE will be classified using the following criteria: 
 Mild:  These events are usually transient, require minimal or no treatment, and do not 
interfere with the subject’s daily activities. 
 Moderate:  These events result in a low level of inconvenience or concern with the 
therapeutic measures. Moderate events may cause some interference with normal 
functioning but pose no significant or permanent risk of harm. 
 Severe:  These events interrupt a subject’s usual daily activity and may require 
systemic drug therapy or other treatment. Severe events are usually incapacitating. 
 
Changes in the severity of an AE should be documented as a new event to allow an 
assessment of the duration of the event at each level of intensity to be performed. 
8.19.4 
Laboratory Findings  
Protocol-defined safety laboratory test results will be analyzed as part of specific laboratory 
safety analyses. Additional laboratory test results at other timepoints may be available to the 
investigator as part of standard clinical practice. Throughout the study, laboratory-related 
abnormalities should be recorded as AEs only if considered clinically significant, outside the 
range of expected values given the subject’s Baseline assessments and clinical course, and 
not known to be part of another AE diagnosis. 
8.19.5 
Worsening or Progression of Disease Under Study  
Worsening or progression of NTM pulmonary disease caused by Mycobacterium abscessus 
including worsening of baseline symptoms, should not be recorded as an AE unless the 
worsening/progression also meets the criteria for a serious AE (in which case the event also 
should be reported as an SAE). If worsening or progression of disease under study requires 
additional antibiotic therapy, subject will be discontinued from test article and this reason for 
discontinuation will be recorded in the eCRF.  
8.19.6 
Pregnancies  
To ensure subject safety, each pregnancy in a subject on test article must be reported to the 
sponsor within 1 business day of learning of its occurrence. Test article should be 
discontinued immediately, and the pregnancy should be followed up to determine outcome,

including spontaneous or voluntary termination, details of the birth, and the presence or 
absence of any birth defects, congenital abnormalities, or maternal and/or newborn 
complications. 
Pregnancy should be recorded on a Clinical Trial Pregnancy Form and reported by the 
investigator to the sponsor. Pregnancy follow-up should be recorded on the same form and 
should include an assessment of the possible relationship to the test article of any pregnancy 
outcome. Any SAE experienced during pregnancy must be reported on the SAE Report 
Form. 
8.20 Concomitant Medication Assessments  
The investigator should instruct the subject to notify the study site about any new 
medications they take after the start of the test article. 
All prescription medications, over-the-counter drugs, and recreational drugs taken within the 
timeframe defined in the entry criteria prior to the start of the study and during the study, 
must be recorded in the eCRF. Medication entries should be specific to trade name, the single 
dose and unit, the frequency and route of administration, the start and discontinuation dates 
or indication that the medication continues, and the reason for therapy.  
8.21 Subject Discontinuation or Withdrawal  
Reasons why a subject may discontinue or be withdrawn from the study include, but are not 
limited to, AE, worsening of disease under study, lost to follow up, withdrawal by subject, 
physician decision, death, and other (specify reason eg, subject non-compliance or study 
termination by the sponsor). Subjects may voluntarily withdraw from the study for any 
reason at any time. Subjects are considered withdrawn from the study if they state an 
intention to withdraw, or fail to return for visits, or become lost to follow up for any other 
reason. In the event a subject is lost to follow-up, every possible effort should be made to 
contact the subject and determine the reason for discontinuation as local law permits. The 
due diligence measures taken must be documented in the subject’s source documents. If 
premature withdrawal from the study occurs, the investigator should determine the primary 
reason for a subject’s premature withdrawal from the study and record the date and primary 
reason on the eCRF. Subjects who discontinue study treatment prematurely should complete 
the EOT visit and Safety Follow-up assessment, if possible (see Schedule of Assessments – 
Appendix 1). Exceptions to this include subjects who withdraw consent or are considered lost 
to follow-up after appropriate due diligence measures have been taken. 
Site personnel must also contact the IxRS to register the subject’s discontinuation from test 
article. 
For subjects who are lost to follow up, the investigator should show “due diligence” by 
documenting in the source documents the steps taken to contact the subject (eg, dates of 
telephone calls, registered letters, etc).

9 STUDY ACTIVITIES  
9.1 
Screening Period  
Screening procedures (as detailed in Appendix 1) may begin once informed consent is 
obtained and will be used to establish subject eligibility and baseline characteristics for each 
subject. The Screening period for this study is up to 8 weeks to allow sufficient time for 
collection and analysis of sputum specimens. Subjects may be randomized as soon as all 
screening procedures have been performed and results have been received to verify eligibility 
criteria. 
9.2 
Double-blind Treatment Period  
The double-blind treatment period is approximately 3 months (84 days) in duration. Subjects 
who meet all of the inclusion criteria and none of the exclusion criteria may be randomized. 
In-clinic visits will occur at Baseline/Day 1, Day 28 (± 3 days), Day 56 (± 3 days), and 
Day 84/EOT (+ 5 days /- 2 days). 
A tele-visit (phone call or virtual) will occur at Day 14 (± 2 days) to assess safety via review 
of AEs and concomitant medications.  
9.3 
Follow-up Period  
9.3.1 
30-Day Safety Follow-up Call  
The Follow-up assessment should be conducted 30 to 37 days following the subject’s last 
dose of test article to assess safety via review of AEs and concomitant medications. This 
evaluation should also be conducted for any prematurely withdrawn subject except for 
subjects who withdraw consent or are lost to follow up. The Follow-up assessment may be 
conducted via telephone or at the investigator’s discretion, the safety follow-up can be an 
office visit.

10 STUDY SUSPENSION, TERMINATION, AND COMPLETION  
10.1 Study Completion and Post-study Test Article  
A subject will have successfully completed the study after the planned test article regimen 
has been administered, and all assessments and visits have been performed up through the 
final Follow-up assessment. The study will be completed when the last subject has either 
discontinued or completed the Follow-up assessment. 
No long-term follow up of subjects is planned, with the exception of pregnancies, as 
described in Section 8.19.6, and SAEs described in Section 8.15. 
Sites will be notified by either the sponsor or IxRS to stop enrollment when the desired 
number of treated subjects have been enrolled. Subjects already consented, but not yet 
randomized, will be allowed to continue screening procedures. 
Upon study completion, the investigator will provide the sponsor, IRB/IEC/REB, and 
regulatory agency with final reports and summaries as required by regulations. The 
investigator must submit a written report to the sponsor and the IRB/IEC/REB within 
3 months after the completion or termination of the study. 
10.2 Study Suspension or Termination  
The sponsor may suspend or terminate the study or part of the study at any time for any 
reason. Should termination be necessary, subjects should be seen as soon as possible and 
treated as described in Section 8.21 for prematurely withdrawn subjects. The investigator 
may be informed of additional procedures to be followed to ensure that adequate 
consideration is given to the protection of the subject’s interests. The investigator will be 
responsible for informing IRBs and/or Ethics Committees of the early termination of the 
study. 
If the investigator suspends or prematurely terminates their participation in the study, the 
investigator will promptly inform the sponsor and the IRB/IEC/REB and provide them with a 
detailed written explanation. Subjects should be seen as soon as possible and treated as 
described in Section 8.21 for prematurely withdrawn subjects. The investigator will also 
return all test articles, containers, and other study materials to the sponsor.

12 PLANNED STATISTICAL METHODS  
12.1 General Considerations  
All analyses of data for this study will comply with International Council on Harmonisation 
(ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use 
(ICH-E9) and the sponsor’s guidance documents and standards. Statistical analyses will be 
performed using Statistical Analysis Software (SAS®). 
The statistical analysis plan (SAP) incorporating the sections below, along with mock tables, 
figures, and listings shells, will be prepared, approved, and finalized by the sponsor prior to 
database lock. This plan will define populations for analysis, outline all data handling 
conventions, and specify statistical methods to be used for analysis of safety and efficacy. 
Descriptive statistics, including the numbers and percentages for categorical variables, and 
the numbers, means, standard deviation, medians, minimums, and maximums for continuous 
variables will be provided. Exploratory analyses may also be performed. Listings of 
individual subject’s data will be produced. 
All eCRFs must be completed, entered, and source-data verified; all safety and microbiology 
laboratory results must have been reported; all AEs must have been fully characterized (eg, 
relationship to test article determined) and coded; and all queries must have been resolved 
prior to database lock and unblinding. Determination of inclusion in the analysis populations, 
characterization of protocol deviations as major/minor, and final approval of the SAP will 
also be completed prior to database lock. 
12.2 Determination of Sample Size  
As the study is exploratory with respect to determination of efficacy, the sample size 
determination is provided to better ensure sufficient subjects are enrolled to provide an initial 
assessment of efficacy rather than test a specific hypothesis. A sample size of 75 subjects will 
provide approximately 80% power to detect an absolute treatment difference of 30% in 
clinical response rate at Day 84, based on clinical response rates of 15% and 45% in the 
placebo and omadacycline treatment groups respectively, using a Mantel-Haenszel test with 
2-sided alpha level of 0.05. 
12.3 Analysis Populations  
The following subject analysis sets have been defined: 
 Intent-to-treat (ITT) Analysis Set includes all randomized subjects. 
 Per-Protocol Analysis Set includes all randomized subjects who received at least 
1 dose of test article and completed the study without major protocol deviations that 
affect the assessment of efficacy. 
 Safety Analysis Set includes all subjects who received at least 1 dose of test article.

12.4 Demographics, Baseline Characteristics, and Subject Disposition  
Demographics (including age, gender, ethnicity, and race) and baseline characteristics will be 
summarized in the ITT Analysis Set by treatment group.  
Descriptive statistics of the duration of test article treatment will be provided by treatment 
group in the ITT and Safety Analysis Sets. The number and percentage of subjects who 
prematurely discontinued test article and the reason for discontinuation as well as the number 
and percentage of subjects prematurely discontinuing the study and the primary reason for 
discontinuation will be presented by treatment group in the ITT Analysis Set. 
12.5 Efficacy Endpoint(s)  
The study is exploratory with respect to efficacy determination. Efficacy will be evaluated 
based on endpoints defined by subject-reported NTM symptoms, subject-reported outcomes 
and quality of life measures, and microbiologic assessment. Additional endpoints to assess 
efficacy will be defined in the SAP. Nominal p-values will be provided as descriptive 
statistics. 
12.5.1 
Primary Efficacy Endpoints  
The primary determination of efficacy is based on subject assessment of symptoms. Several 
definitions of clinical response will be defined, including but not limited to those listed in 
Section 4; all definitions will be provided in the SAP.  
For each definition, the number and percentage of subjects with a clinical response and no 
clinical response will be summarized by treatment group in the ITT Analysis Set. Exact 
2-sided 95% confidence intervals (CIs) for the point estimates of the clinical response rates in 
each treatment group will be determined using the Clopper-Pearson method. The odds ratio 
(omadacycline relative to placebo) and p-value will be calculated using Cochran-Mantel-
Haenszel test, stratified by prior antibiotic use. The estimand attributes for clinical response 
will be provided in detail in the SAP. In general, clinical response will use both a treatment 
and composite policy strategy for handling intercurrent events. Subjects who receive 
alternative antibiotic therapy for treatment of the NTM infection and/or die before reaching 
Day 84 will be considered as not achieving clinical response. Subjects with missing data due 
to withdrawal of consent will also be considered as not achieving clinical response. 
Analyses will be repeated in the Per-Protocol Analysis Set as detailed in the SAP. 
12.5.2 
Secondary Efficacy Endpoints  
12.5.2.1 
Patient-Reported Outcomes and Quality of Life  
For each patient-reported outcome and quality of life endpoint, analyses will be conducted in 
the ITT Analysis Set. Available data will be used; there will be no substitutions for missing 
data.

The QOL-B includes domains for physical functioning, role functioning, vitality, emotional 
functioning, social functioning, treatment burden, health perceptions and respiratory 
symptoms. For each domain, scores will be standardized on a 0 to 100 scale. Descriptive 
statistics for each domain at baseline and each visit will be presented by treatment group. The 
change from baseline to each visit will be analyzed using an analysis of covariance 
(ANCOVA) and the least squares (LS) mean, standard error (SE) of the LS mean and 2-sided 
95% CI for the LS mean will be provided for each treatment group. The difference in LS 
means between treatment groups, 2-sided 95% CI and p-value will also be provided. 
For the SGRQ, the global score and score for each component (symptoms, activity, and 
impacts) will be determined. Descriptive statistics for the global score and each component 
score at each visit will be presented by treatment group. The change from baseline to each 
visit will be analyzed using an ANCOVA, and the LS mean, and 2-sided 95% CI for the LS 
mean will be provided for each treatment group. The difference in LS means between 
treatment groups, 2-sided 95% CI and p-value will also be provided. 
For the PROMIS Fatigue 7a Short Form, raw scores are converted to a standardized score. 
Descriptive statistics for the standardized score at baseline and each visit will be presented by 
treatment group. The change from baseline to each visit will be analyzed using an ANCOVA, 
and the LS mean, SE of the LS mean, and 95% CI for the LS mean will be provided for each 
treatment group. The difference in LS means between treatment groups, 95% CI and p-value 
will also be provided. 
For the PGI-S, the number and percentage of subjects with each response will be presented 
by visit and treatment group. The PGI-S will also be categorized as mild/not present vs. 
moderate/severe and the number and percentage of subjects in each category will be 
presented by visit and treatment group. Exact 2-sided 95% CIs using the Clopper-Pearson 
method for the percent improved and a p-value from Fisher’s exact test will be provided. 
For the PGI-C, the number and percentage of subjects with each response will be presented 
by visit and treatment group. The PGI-C will also be categorized as improved vs. no 
change/worse and the number and percentage of subjects in each category will be presented 
by visit and treatment group. Exact 2-sided 95% CIs using the Clopper-Pearson method for 
the percent improved and a p-value from Fisher’s exact test will be provided. 
Descriptive statistics for severity of illness from the CGI change from baseline for each visit 
will be presented by treatment group. Descriptive statistics of the global improvement and 
the efficacy index from the CGI will also be provided by treatment group for each visit. A 
p-value from the Wilcoxon rank sum test for each outcome will also be presented. 
At each visit based on the NTM Symptom Assessment Questionnaire, the number and 
percentage of subjects with a new symptom (compared with baseline) with severity worse 
than mild and no new symptoms with a severity worse than mild will be summarized by 
treatment group. Shift tables from baseline for each symptom at each visit will also be 
provided.

12.5.2.2 
Microbiological Response  
The number and percentage of subjects with a decrease in the mycobacterial load will be 
determined by treatment group at Day 84 in the ITT Analysis Set. Exact 2-sided 95% CIs for 
the point estimate of the percentage of subjects of subjects with a decrease in mycobacterial 
load in each treatment group will be determined using the Clopper-Pearson method. The odds 
ratio (omadacycline relative to placebo) and p-value will be calculated using 
Cochran-Mantel-Haenszel test, stratified by prior antibiotic use. 
Kaplan-Meier methods will be utilized to determine the time to growth in liquid media only 
and time to first negative sputum culture in the ITT Analysis Set. Time to growth in liquid 
medium only will be defined as the number of days from the date of test article 
administration to the date of the first assessment where growth is detected in liquid medium 
only. Time to first negative sputum culture is defined as the number of days from the date of 
test article administration to the date of the first negative sputum culture. Subjects who died, 
withdrew, or took alternative antibiotic therapy for treatment of the NTM infection prior to 
growth in liquid medium only or negative sputum will be censored at the date of the death, 
study withdrawal, or the start date of the alternative antibiotic therapy respectively. The 
median, 25th and 75th percentile for time to growth in liquid media and time to first negative 
sputum culture will be provided with 2-sided 95% CIs. A p-value will be determined using a 
log-rank test. 
12.6 Safety Endpoint(s)  
All safety data will be analyzed in the Safety Analysis Set. Adverse events will be coded 
using the Medical Dictionary of Regulatory Activities. The incidence of treatment-emergent 
adverse events will be presented by system organ class (SOC) and preferred term (PT), by 
SOC, PT and relationship to test article, and by SOC, PT and severity. Serious AEs and 
treatment-emergent adverse events that lead to discontinuation of the test article will also be 
presented by SOC and PT. Descriptive statistics for clinical laboratory, vital signs, and ECG 
parameters, including change from baseline, will be presented by timepoint collected and for 
the overall most abnormal post-baseline value (for clinical laboratory and vitals sign 
parameters). Incidences of potentially clinically significant clinical laboratory results, vital 
signs and ECG parameters as defined in the SAP, will also be summarized by timepoint 
collected and the overall most abnormal post-baseline value (for clinical laboratory and vital 
sign parameters). 
12.7 Data Monitoring Committee  
Given the exploratory nature of this Phase 2 study using a product with a well-established 
safety profile, a data monitoring committee will not be utilized for this study.

reviews the data for safety information. The data are reviewed for completeness and logical 
consistency. Automated validation checks identify missing data, out-of-range data, and other 
data inconsistencies. The central safety and microbiology data will be processed 
electronically. Requests for data clarification are forwarded to the study site for resolution. 
13.6 Protocol Adherence  
13.6.1 
Violations/Deviations  
Investigators will agree to apply due diligence to avoid protocol deviations. Under no 
circumstances should the investigator contact the sponsor or its agents to request approval of 
a prospective protocol deviation, as no authorized deviations are permitted. If the investigator 
feels a protocol deviation would improve the conduct of the study this must be considered a 
protocol amendment and it cannot be implemented unless such an amendment is agreed upon 
by the sponsor and approved by the IRB/IEC/REB. All significant protocol deviations will be 
recorded and reported in the Clinical Study Report. 
13.6.2 
Protocol Amendments  
Any change or addition to the protocol can only be made in a written protocol amendment 
that must be approved by the sponsor, Health Authorities where required, and the 
IRB/IEC/REB. Only amendments that are required for subject safety may be implemented 
prior to IRB/IEC/REB approval. Notwithstanding the need for approval of formal protocol 
amendments, the investigator is expected to take any immediate action required for the safety 
of any subject included in this study, even if this action represents a deviation from the

protocol. In such cases, the sponsor should be notified of this action and the IRB/IEC/REB at 
the study site should be informed within 10 working days. 
13.7 Subject Injury  
In general, subject to specific provisions in the clinical study agreement (CSA), if a subject is 
injured as a direct result of a test article, the sponsor will pay for reasonable and necessary 
medical treatment for the injury, to the extent that such expenses are not covered by the 
subject’s medical insurance, a government program, or other responsible third party. If laws 
or regulations of the locality in which the study is taking place require additional payment of 
expenses, the sponsor shall comply with such laws or regulations. Where applicable, the 
sponsor has taken specific national insurance. 
13.8 Pre-study Documentation  
The investigator must provide the sponsor with the following documents before enrolling any 
subjects: 
 Completed and signed Form FDA 1572 or equivalent. 
 All applicable country-specific regulatory forms. 
 Current signed and dated curricula vitae and medical license (as applicable) for the 
investigator, sub-investigators, and other individuals having significant investigator 
responsibility who are listed on the Form FDA 1572 or equivalent, or the clinical 
study information form. 
 Copy of the IRB/IEC/REB approval letter for the protocol and informed consent. All 
advertising, recruitment, and other written information provided to the subject must 
be approved by the IRB/IEC/REB. Written assurance of continuing approval (at least 
annually) as well as a copy of the annual progress report submitted to the 
IRB/IEC/REB must also be provided to the sponsor. 
 Copy of the IRB/IEC/REB-approved informed consent document to be used. 
 Where applicable, a list of the IRB/IEC/REB members and their qualifications, and a 
description of the committee’s working procedure. 
 Copy of the protocol sign-off page signed by the investigator.

Sputum Induction Guidelines 
Introduction 
Collection of adequate sputum samples (approximately 5 mL) is critical. Sputum samples 
will be collected by the subject (at home) and/or at the study site. In the event the subject is 
unable to spontaneously expectorate the required volume of sputum, induction may be 
performed at the study site by qualified site staff. This guidance document is intended to 
provide recommendations for obtaining an adequate sputum sample via sputum induction. 
Recommended Equipment 
 Standard handheld nebulizer – thoroughly cleaned and disinfected 
 Sputum specimen containers with labels 
 Sputum collection tubes (provided by the Central Laboratory) 
 Hypertonic sodium chloride solution (at minimum 3%, plus 5% and 7% if needed) 
 Other clinic supplies (eg, disinfectant/germicidal/alcohol wipes, gloves, masks, 
tissues, paper towels, etc.) 
 
CONTRAINDICATIONS TO SPUTUM INDUCTION 
 This procedure should not be performed in subjects in which severe coughing may be 
harmful, such as subjects with: 
o Recent or recurrent hemoptysis 
o Acute respiratory distress 
o Acute hypoxia (SaO2 in room air of < 90%) 
o Known pneumothorax 
o Rib fractures or chest wall musculoskeletal injury 
o Unstable cardiac conditions 
o Recent eye surgery 
 
Instructions: 
Preparation 
 Subjects should be instructed not to eat at least 1 hour prior to sputum induction. 
 Subjects should be informed of the purpose of this procedure before commencing.  
 The procedure should be discussed with the subject: 
o They will experience a salty taste in their mouth 
o They may cough 
o They will likely produce lung secretions that they will need to expectorate 
o If they have pre-existing hyperreactive airways eg, asthma, they will receive 
pre-medication with an inhaled bronchodilator 
 Sputum induction should occur in a private, contained room, following clinic 
processes to ensure sterilization and prevent contamination.  
 Site staff performing induction should wear gloves and an N95 mask for the duration 
of the procedure.

 All collection containers should have a sputum collection label completed with 
subject identifiers (ie: subject #, visit ID, collection date and time). 
 The induction procedure should start with using lower concentrations of saline (eg, 
3%) as per the investigator’s discretion. Approximately 3-6 mL of hypertonic saline 
should be placed in the nebulizer. 
 Subjects should be sitting up or in a semi-fowler position. 
 
Nebulization 
 Nebulization time is approximately 10 minutes in total, with breaks in nebulization at 
5-minute intervals or if the patient has respiratory distress, excessive coughing. 
 Nebulization may extend to 15 minutes if the patient is in no distress and more 
sputum needs to be collected. 
 Nebulization should stop at 15 minutes total time, even if inadequate sputum is 
collected. 
 The saline concentration may be increased to a maximum of 7% per investigator 
discretion. 
 Subjects should be instructed to breathe slowly and deeply (pausing at peak 
inspiration) through the nebulizer mouthpiece inhaling the saline mist.  
 If the subject needs to expectorate during nebulization, turn off the nebulizer and 
allow the subject to expectorate into the container. 
o If a sufficient specimen is collected, procedure can stop.  
o If an insufficient volume of sputum is collected, the subject should resume the 
nebulization treatment and complete the full 15-minute duration in three 
5-min intervals.  
 Subjects should be encouraged to blow their nose as needed during the induction to 
help prevent nasal secretions from becoming mixed with the sputum specimen. 
 Upon completion, subjects should take a few deep breaths, swallow the extra saliva in 
their mouth and attempt to forcefully cough up a sputum sample into a sputum 
container. The container should be closed immediately after the appropriate volume 
of sputum (approximately 5 mL) is collected. 
 Closely monitor the subject for tolerability issues or side effects. 
 The sputum sample should be refrigerated until it is sent to the central specialty 
microbiology laboratory. 
 Please refer to the Central Laboratory Manual for further instructions on packaging 
and shipping specimens to the lab.
