Eligibility
Key inclusion criteria
1. Males at least 12 years of age, non-ambulatory 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

3. Male participants with partners of childbearing potential must use contraception
during the conduct of the study, and for 12 weeks after the last dose of study drug.

4. Medical history includes diagnosis of DMD and confirmed Duchenne mutation using a
validated genetic test

5. Brooke Score for Arms and Shoulders =5

6. Able to undergo MRI test for the upper arm extremities (Biceps Brachii muscle) and
cardiac muscle

7. Able to perform spirometry

8. Average (of Screening and Day 0) percent predicted forced vital capacity (FVC) between
45 and 85, inclusive

9. Left ventricular ejection fraction =50% as determined by local cardiac MRI read at
screening or within 3 months prior to randomization (Day 0)

10. If participants have a history of cardiomyopathy, then participant must be on a stable
dose of cardiomyopathy/ heart failure medications (for example, angiotensin converting
enzyme inhibitors, aldosterone receptors blockers, angiotensin-receptor blockers, and
betablockers) for at least 1 month prior to screening. If participants have no
diagnosis of cardiomyopathy, then no dose of cardiomyopathy/heart failure medication
is required for eligibility.

11. 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.

12. Agreement to receive annual influenza vaccinations during the course of the study.

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

14. 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.

15. 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
12 Years
Maximum age
No limit
Sex
Males
Can healthy volunteers participate?
No
Key exclusion criteria
1. Previous exposure to pamrevlumab

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

3. 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

3. hypersensitivity reaction to Gadolinium-based Contrast Agents (GBCA) required for
MRI acquisition

4. 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
[exondys 51], ataluren, golodirsen [vyondys 53], casimersen [amondys 45]) within 5
half-lives of screening, whichever is longer, with the exception of the systemic
corticosteroids, including deflazacort

5. Severe uncontrolled heart failure (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

6. Arrhythmia requiring anti-arrhythmic therapy

7. Requires =16 hours continuous ventilation

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

9. 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

10. 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 or psychiatric conditions
