Key exclusion criteria
Exclusion criteria:

- Hypochondroplasia or short stature condition other than ACH

- Have any of the following:

- Hypothyroidism or hyperthyroidism

- Insulin-requiring diabetes mellitus

- Autoimmune inflammatory disease

- Inflammatory bowel disease

- Autonomic neuropathy

- History of any of the following:

- Renal insufficiency defined as serum creatinine > 2 mg/dL

- Chronic anemia

- Baseline systolic blood pressure (BP) < 70 millimeters of mercury (mm Hg) or
recurrent symptomatic hypotension (defined as episodes of low BP generally
accompanied by symptoms ie, dizziness, fainting) or recurrent symptomatic
orthostatic hypotension

- Cardiac or vascular disease

- Have a clinically significant finding or arrhythmia on screening
electrocardiogram (ECG) that indicates abnormal cardiac function or
conduction or Fridericias corrected QTc-F > 450 msec

- Have an unstable condition likely to require surgical intervention during the study
(including progressive cervical medullary compression or severe untreated sleep apnea)

- Decreased growth velocity (< 1.5 cm/yr) over a period of 6 months or evidence of
growth plate closure (proximal tibia, distal femur)

- Treated with growth hormone, insulin-like growth factor 1 (IGF-1), or anabolic
steroids in the previous 6 months or treatment greater than 6 months at any time

- Greater than 1 month treatment with oral corticosteroids (low-dose ongoing inhaled
steroid for asthma, or intranasal steroids, are acceptable) in the previous 12 months

- Planned or expected to have limb-lengthening surgery during the study period. Subjects
with previous limb- lengthening surgery may enroll if surgery occurred at least 18
months prior to the study and healing is complete without sequelae.

- Planned or expected bone-related surgery (ie. surgery involving disruption of bone
cortex, excluding tooth extraction), during the study period. Subjects with previous
bone-related surgery may enroll if surgery occurred at least 6 months prior to the
study and healing is complete without sequelae.

- Had a fracture of the long bones or spine within 6 months prior to screening

- History of severe untreated sleep apnea

- New initiation of sleep apnea treatment (e.g. CPAP or sleep apnea-mitigating surgery)
in the previous 2 months prior to screening

- History of hip surgery or hip dysplasia atypical for achondroplastic subjects

- History of clinically significant hip injury in the 30 days prior to screening

- History of slipped capital femoral epiphysis or avascular necrosis of the femoral head

- Abnormal findings on baseline clinical hip exam or imaging assessments that are
determined to be clinically significant

- Concurrent disease or condition that would interfere with study participation or
safety evaluations, for any reason

- Condition or circumstance that places the subject at high risk for poor treatment
compliance or for not completing the study
