How TYMLOS rebuilds bone.1
TYMLOS quickly shifts the balance during bone remodeling to favor bone formation.1-4
TYMLOS is a PTHrP(1–34) analog that acts as an agonist at the PTH1 receptor. It activates the cAMP signaling pathway, which triggers the remodeling process in favor of bone formation.1,5-8

TYMLOS quickly stimulates, then sustains, bone formation.1
Mineralizing surface increase at 3 months†2
Mechanism of action representations are not meant to imply clinical efficacy. No new safety signals were seen. Adverse events were similar to those seen in the ACTIVE trial.1,2
†3 months is the amount of time it takes bones to form and mineralize in healthy adults.2-4
Open-label study evaluating the effects of TYMLOS on indices of bone formation.2
Study design: Open-label, single-arm study that evaluated the effects of TYMLOS on indices of bone formation using transiliac bone biopsies in postmenopausal women with osteoporosis. 23 biopsies were included in the safety population; 19 biopsies were evaluable. Subjects received double fluorochrome labels before treatment and before biopsy collection at 3 months.
Primary endpoint: Change in the mineralizing surface per unit of bone surface (MS/BS) in trabecular bone, from baseline to 3 months.
Secondary endpoints:
- MS/BS across cortical and periosteal surfaces2
- Remodeling- and modeling-based bone formation2
Inclusion criteria:
- Postmenopausal women with osteoporosis, aged 50-85 years2
- BMD: T-score ≥ –2.5 at the lumbar spine or hip (including femoral neck or total hip) OR BMD+Fracture History: T-score ≥ –2.0 at the lumbar spine or hip and a recent (>5 years) low-trauma vertebral, forearm, humerus, sacral, pelvic, femoral, or tibial fracture2
Exclusion criteria: Patients with unevaluable lumbar spine or hip BMD, a history of bone disorders, metabolic bone disease, malabsorption, cancer in the past 5 years, osteosarcoma at any time, or prior radiotherapy (besides radioiodine) were excluded. Patients with a known hypersensitivity to TYMLOS, those who received prior treatment with PTH or PTHrP, denosumab, or IV bisphosphonates, took medications that interfere with bone metabolism within 6 months, or received treatment with oral bisphosphonates within 3 years were not eligible for this study.2
Study limitations2:
- Consider open-label study limitations when interpreting results. This open-label study was not blinded. These results are not meant to imply fracture efficacy
- Single-arm study with no placebo group comparison and included only caucasian female participants
- Since the study had no control arm, a quadruple labeling procedure was used for internal control, allowing for a baseline comparison of bone formation indices within the same sample
- Data generated from bone biopsies are variable, between subjects, and between biopsies taken from the same subject
- While significant changes in these parameters are unlikely after 3 months of treatment, this labeling procedure does limit the ability to evaluate the effect of treatment on bone microarchitectural endpoints
- Transiliac bone biopsies may not precisely reflect changes in bone at weight-bearing sites

Your patients could be at imminent risk for fracture
AACE/ACE guidelines define patients at very high risk for fracture based on9:
- T-score of –3.0 or worse
- Fracture: a history of recent fracture (< year), multiple fractures, or fracture while on osteoporosis treatment or drugs causing skeletal harm
- FRAX®: Very high fracture probability (>30% major osteoporosis fracture or >4.5% hip fracture)
- High risk for falls
In addition, patients unable to use antiresorptive therapy or those that experience progressive bone loss while on antiresorptive therapy remain at elevated risk.
FRAX = Fracture Risk Assessment Tool, used to estimate the risk of fracture in the next 10 years.
