Twenty-Four Month Extension Study of BA058-05-003 (Abaloparatide) in Participants With Osteoporosis

Nonvertebral fractures were defined as clinical fractures that included: 1) those of the hip, wrist, forearm, shoulder, collar bone, upper arm, ribs, upper leg (not hip), knee, lower leg (not knee or ankle), foot, ankle, hand, pelvis (not hip), tailbone, and other; and 2) those associated with low trauma, defined as a fall from standing height or less; a fall on stairs, steps or curbs; a minimal trauma other than a fall; or moderate trauma other than a fall. Complete results for Study BA058-05-003 are reported in the ClinicalTrials.gov Study Record NCT02653417.

Total hip BMD were measured via DXA. Complete results for Study BA058-05-003 are reported in the ClinicalTrials.gov Study Record NCT02653417.

Femoral neck BMD were measured via DXA. Complete results for Study BA058-05-003 are reported in the ClinicalTrials.gov Study Record NCT02653417.

Lumbar spine BMD were measured via DXA. Complete results for Study BA058-05-003 are reported in the ClinicalTrials.gov Study Record NCT02653417.

A TEAE is any untoward medical occurrence or undesirable event(s) experienced in a participant that begins or worsens following administration of study drug, whether or not considered related to study drug by Investigator. A serious adverse event (SAE) was an adverse event (AE) resulting in any of the following outcomes or deemed significant for any other reason, death, initial or prolonged inpatient hospitalization, life-threatening experience (immediate risk of dying), congenital anomaly/birth defect, or persistent or significant disability/incapacity. Intensity for each AE was defined as mild, moderate, or severe. AEs included both SAEs and non-serious AEs. AEs whose causal relation was characterized as Possible or Probable were considered as related to study drug. AEs were coded using Medical Dictionary for Regulatory Activities (MedDRA). A summary of serious and all other non-serious adverse events, regardless of causality, is located in the Reported Adverse Events module.

Serum Chemistry laboratory parameters that were evaluated via notable criteria (presented in parentheses) included: sodium (Low: ≤129; High: ≥148 milliequivalent per liter \[mEq/L\]), potassium (Low: ≤3.2; High: ≥5.5 mEq/L), albumin (\<2.5 grams \[g\]/deciliter \[dL\]), total protein (\<5 g/dL), glucose (Low: ≤54; High: \>125 mg/dL \[fasting\] or \>200 milligrams \[mg\]/dL \[random\]), creatinine (≥2.1 mg/dL), aspartate aminotransferase (AST) (≥5.1\*upper limit of normal \[ULN\]), alanine aminotransferase (ALT) (≥5.1\*ULN), alkaline phosphatase (AP) (≥3.1\*ULN), total bilirubin (≥1.51\*ULN \[with any increase in liver function tests\] ≥2.0\*ULN \[with normal liver function tests\]), creatine kinase (≥3.1\*ULN), total cholesterol (\>226 mg/dL), and total calcium (Low: ≤7.4; High: ≥11.6 mg/dL). Only the serum chemistry parameters with at least 1 participant with a notable laboratory value are presented.

Hematology laboratory parameters that were evaluated via notable criteria (presented in parentheses) included: Absolute Eosinophils (\>5000 cells/mm\^3), Absolute Lymphocytes (≤499 cells/mm\^3), Absolute Neutrophils (≤999 cells/mm\^3), % Eosinophils (\>50%), % Lymphocytes (≤5%), % Neutrophils (≤10%), Hemoglobin (Low: ≤9.4 g/dL; High: change from baseline ≥2.1 g/dL), Platelets (≤99000 cells/mm\^3), and White Blood Cells (Low: ≤1499 cells/mm\^3; High: ≥20001 cells/mm\^3). Only the hematology parameters with at least 1 participant with a notable laboratory value are presented.

Coagulation laboratory parameters that were evaluated via notable criteria (presented in parentheses) included: Activated Partial Thromboplastin Time (≥1.41\*ULN), Prothrombin Time (≥1.21\*ULN). Because the Activated Partial Thromboplastin Time was the only coagulation laboratory parameter with at least 1 participant with a notable laboratory value, this is the only parameter presented below.

Urine laboratory parameters that were evaluated via notable criteria (presented in parentheses) included: Glucose (2+), Protein (2+), Blood (\>50 red blood cells per high-power field \[rbc/hpf\]).
