    Summary
    Wrist fractures over 43 months occurred in 15 women with ABL/ALN (KM estimate, 2.8%) and 20 with PBO/ALN (KM estimate, 3.6%) (HR = 0.77, 95% CI 0.39, 1.50; P = not significant).

    In postmenopausal women, abaloparatide followed by alendronate increased ultradistal radius BMD more than placebo followed by alendronate at month 25.

    Summary
    At cumulative month 25, mean increase from ACTIVE baseline in ultradistal radius BMD was 1.1% (standard error, 0.49%) with ABL/ALN vs - 0.8% (0.43%) with PBO/ALN (P < 0.01).

    Summary · context
    Our objective was to determine the efficacy of ABL followed by ALN vs placebo (PBO) followed by ALN on forearm BMD and fracture risk over 43 months in ACTIVExtend.
    Summary · context
    Ultradistal and 1/3 radius BMD (ACTIVE baseline to month 43) were measured (ABL/ALN, n = 213; PBO/ALN, n = 233).

Studies that did not test the peptide alone2

In this study, Abaloparatide (Tymlos) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Abaloparatide (Tymlos).

    In postmenopausal women, one-third radius BMD decreases similar with abaloparatide and placebo persisted during subsequent alendronate treatment.
