Eligibility
Key inclusion criteria
Age, and consent:

1. Males at least 6 to <12 years of age at screening initiation

2. Written consent by participant and/or legal guardian as per regional/ country and/or
Institutional Review Board (IRB)/Independent Ethics Committee (IEC) requirements

DMD diagnosis:

3. Medical history includes diagnosis of DMD and confirmed Duchenne mutation, including
status of exon 44 using a validated genetic test.

Pulmonary criteria:

4. Average (of screening and Day 0) percent predicted forced vital capacity (FVC) above
45%

5. On a stable dose of systemic corticosteroids for a minimum of 6 months, with no
substantial change in dosage for a minimum of 3 months (except for adjustments for
changes in body weight) prior to screening. Corticosteroid dosage should be in
compliance with the DMD Care Considerations Working Group recommendations (for
example, prednisone or prednisolone 0.75 mg/kg per day or deflazacort 0.9 mg/kg per
day) or stable dose. A reasonable expectation is that dosage and dosing regimen would
not change significantly for the duration of the study.

Performance criteria:

6. Able to complete 6-minute walking distance (6MWD) test with a distance of at least 270
meters but no more than 450 meters on two occasions within 3 months prior to
randomization with =10% variation between these two tests.

7. Able to rise (TTSTAND) from floor in <10 seconds (without aids/orthoses) at screening
visit.

8. Able to undergo magnetic resonance imaging (MRI) test for the lower extremities vastus
lateralis muscle.

Vaccination:

9. Agreement to receive annual influenza vaccinations during the conduct of the study.

Laboratory criteria:

10. Adequate renal function: cystatin C =1.4 mg/liter (L)

11. Adequate hematology and electrolytes parameters:

1. Platelets >100,000/microliter (µL)

2. Hemoglobin >12 grams (g)/deciliter (dL)

3. Absolute neutrophil count >1500/µL

4. Serum calcium (Ca), potassium (K), sodium (Na), magnesium (Mg) and phosphorus (P)
levels are within a clinically accepted range for DMD participants

12. Adequate hepatic function:

1. No history or evidence of liver disease

2. Gamma glutamyl transferase (GGT) =3x upper limit of normal (ULN)

3. Total bilirubin =1.5xULN
Minimum age
6 Years
Maximum age
11 Years
Sex
Males
Can healthy volunteers participate?
No
Key exclusion criteria
General Criteria:

1. Concurrent illness other than DMD that can cause muscle weakness and/or impairment of
motor function

2. Severe intellectual impairment (for example, severe autism, severe cognitive
impairment, severe behavioral disturbances) preventing the ability to perform study
assessments in the Investigator's judgment

3. Previous exposure to pamrevlumab

4. Body mass index (BMI) =40 kg/square meter (m^2) or weight >117 kg

5. History of

1. allergic or anaphylactic reaction to human, humanized, chimeric or murine
monoclonal antibodies

2. hypersensitivity to study drug or any component of study drug

6. Exposure to any investigational drug (for DMD or not), in the 30 days prior to
screening initiation or use of approved DMD therapies (for example, eteplirsen,
ataluren, golodirsen, casimersen) within 5 half-lives of screening, whichever is
longer with the exception of the systemic corticosteroids, including deflazacort

Pulmonary and Cardiac criteria:

7. Requires =16 hours continuous ventilation

8. Poorly controlled asthma or underlying lung disease such as bronchitis,
bronchiectasis, emphysema, recurrent pneumonia that in the opinion of the investigator
might impact respiratory function

9. Hospitalization due to respiratory failure within the 8 weeks prior to screening

10. Severe uncontrolled heart failure (New York Heart Association [NYHA] Classes III-IV)
or renal dysfunction, including any of the following:

1. Need for intravenous diuretics or inotropic support within 8 weeks prior to
screening

2. Hospitalization for a heart failure exacerbation or arrhythmia within 8 weeks
prior to screening

3. Participants with glomerular filtration rate (GFR) of less than 30 mL/minute
(min)/1.73 m^2 or with other evidence of acute kidney injury as determined by
investigator

11. Arrhythmia requiring anti-arrhythmic therapy

12. Any other evidence of clinically significant structural or functional heart
abnormality

Clinical judgment:

13. The Investigator judges that the participant will be unable to fully participate in
the study and complete it for any reason, including inability to comply with study
procedures and treatment, or any other relevant medical, surgical or psychiatric
conditions
