Disclosures Speaker’s Bureau and Consultant for Abbott nutrition

1. Discuss the current state of osteoporosis impact, detection, and management

2. Review the current osteoporosis screening and monitoring recommendations

3. Examine non-pharmaceutical, lifestyle, and pharmaceutical interventions for low bone density and fracture prevention

4. Illustrate case-based clinical pearls in key problematic areas of osteoporosis management

Pretest Question 1What is the most appropriate treatment recommendation for a 56-year-

old female with a hx of GERD and frequent steroid treatment for migraine breakthroughs? T-score LS -1.9 (6% decline), FN -2.2 (4% decline) Calculated FRAX: 23%, 4%

A. Weight bearing exercises and OTC calcium supplementationB. Alendronate (Fosamax) or Risedronate (Actonel)C. Zoledronic acid (Reclast) or Denosumab (Prolia)D. Romosozumab (Evenity)E. Teriparatide (Forteo) or Abaloparatide (Tymlos)F. HRT or Raloxifene (Evista)

Pretest Question 2 If a 62-year-old African American female with a 7-year hx of

osteoporosis started Alendronate (Fosamax) 5 years ago had declining T-scores, which treatment option is most appropriate?

A. Drug holiday for 1 yearB. Continue Alendronate (Fosamax) C. Drug holiday utilizing Zoledronic acid (Reclast)D. Drug holiday utilizing Denosumab (Prolia) or anabolic agentE. Add an anabolic agent to the current regimen

Pretest Question 3Which treatment option would bring the most benefit to a 64-year-old

female with osteoporosis and a hx of a vertebral compression fracture 3 years ago, after which she started Zoledronic acid (Reclast)? T-score LS -2.1 (stable), FN -3.4 (8% decline)

A. Drug holiday for 1 yearB. Transition to Alendronate (Fosamax) or Risedronate (Actonel)C. Continue Zoledronic acid (Reclast)D. Add Denosumab (Prolia) to the current regimenE. Transition to an anabolic agent

Pretest Question 4 Should a 59-year-old Caucasian male with a five-year hx of COPD and

former smoker frequently on inhaled and PO steroid tx for exacerbations be screened for low BMD?

A. Yes, all men >50 years old should be screenedB. Yes, based on his age >50 and risk factors of history of smoking and steroid useC. No, he does not currently smoke or use steroid treatmentsD. No, he is <70 years old

Impact of Osteoporosis and Fractures

1 in 2 women and 1 in 4 men >50 years old will have a fracture related to osteoporosis >2 million fragility fractures/year in people ≥65 years ~80% of people with a fragility fracture are not screened, identified,

or treated afterward Fragility fractures are associated with decreased bone loss, but the

majority of fractures occur in those with moderate bone loss

Osteoporosis in the WildCase 1

Case Study #1:

56-year-old Hispanic female with a 4-year hx of osteopenia Treatment-naiveHx of frequent steroid treatment for migraine breakthroughsHx of GERDCurrent DXA scan: T-score LS -1.9 (6% decline), FN -2.2 (4% decline) Calculated FRAX: 23%, 4%

Secondary work up is negative, vitamin D is optimal

Question 1What is the most appropriate treatment recommendation for a 56-year-

old female with a hx of GERD and frequent steroid treatment for migraine breakthroughs? T-score LS -1.9 (6% decline), FN -2.2 (4% decline) Calculated FRAX: 23%, 4%

A. Weight bearing exercises and OTC calcium supplementationB. Alendronate (Fosamax) or Risedronate (Actonel)C. Zoledronic acid (Reclast) or Denosumab (Prolia)D. Romosozumab (Evenity)E. Teriparatide (Forteo) or Abaloparatide (Tymlos)F. HRT or Raloxifene (Evista)

Question 1: Answer CWhat is the most appropriate treatment recommendation for a 56-year-old

female with a hx of GERD and frequent steroid treatment for migraine breakthroughs? T-score LS -1.9 (6% decline), FN -2.2 (4% decline) Calculated FRAX: 23%, 4%

C. Zoledronic acid (Reclast) or Denosumab (Prolia)

Rationale: Her current dx is osteoporosis, thus treatment with Alendronate (Fosamax), Risedronate (Actonel), Zoledronic acid (Reclast), or Denosumab (Prolia) recommended. Her hx of GERD precludes oral bisphosphonates. Anabolic agents are an option but not the most appropriate option for a treatment-naïve patient with moderate osteoporosis. HRT and Raloxifene (Evista) are not recommended due to efficacy versus the side effect profile.

Case Study #1:

Osteopenia + high FRAX scores = OsteoporosisDeclining T-scores

Hx of GERD precludes PO bisphosphonate therapyConsider Zoledronic acid (Reclast) which is IV or

Denosumab (Prolia) which is IM


Case Study #2:

62-year-old African American female with a 7-year hx of osteoporosisStarted Alendronate (Fosamax) 5 years ago and reports

adherence Current DXA scan: T-score LS -2.3 (stable), FN -2.6 (3% increase)

Question 2 If a 62-year-old African American female with a 7-year hx of

osteoporosis started Alendronate (Fosamax) 5 years ago had declining T-scores, which treatment option is most appropriate?

A. Drug holiday for 1 yearB. Continue Alendronate (Fosamax) C. Drug holiday utilizing Zoledronic acid (Reclast)D. Drug holiday utilizing Denosumab (Prolia) or anabolic agentE. Add an anabolic agent to the current regimen

Question 2: Answer D If a 62-year-old African American female with a 7-year hx of

osteoporosis started Alendronate (Fosamax) 5 years ago had decliningT-scores, which treatment option is most appropriate?

D. Drug holiday utilizing Denosumab (Prolia) or anabolic agent

Rationale: Due to the duration of therapy, a drug holiday off bisphosphonates is recommended due to the increased risk of ONJ and atypical fractures. Therefore continuing Alendronate (Fosamax) or transitioning to Zoledronic acid (Reclast) is not appropriate. Dual therapy is not currently recommended. With declining T-scores, using an alternative class of medication during the drug holiday should be considered.

Case Study #2:

Recommend drug holiday due to 5 sequential years on bisphosphonateMay resume bisphosphonate therapy after 1 year pending

stability of T-scoresWhat if: T-scores have been declining? Concomitant steroid tx? Severe osteoporosis?Consider alternative agent during drug holiday


Case Study #3:

64-year-old Caucasian female with a 3-year hx of osteoporosis dx after vertebral compression fractureHx of osteoarthritisStarted Zoledronic acid (Reclast) 3 years ago and tolerating wellCurrent DXA scan: T-score LS -2.1 (stable), FN -3.4 (8% decline)Secondary work up including serum calcium and iPTH is

negative, vitamin D is optimal

Question 3Which treatment option would bring the most benefit to a 64-year-old

female with osteoporosis and a hx of a vertebral compression fracture 3 years ago after which she started Zoledronic acid (Reclast)? T-score LS -2.1 (stable), FN -3.4 (8% decline)

A. Drug holiday for 1 yearB. Transition to Alendronate (Fosamax) or Risedronate (Actonel)C. Continue Zoledronic acid (Reclast)D. Add Denosumab (Prolia) to the current regimenE. Transition to an anabolic agent

Question 3: Answer EWhich treatment option would bring the most benefit to a 64-year-old

female with osteoporosis and a hx of a vertebral compression fracture 3 years ago after which she started Zoledronic acid (Reclast)? T-score LS -2.1 (stable), FN -3.4 (8% decline)

E. Transition to an anabolic agent

Rationale: Due to the current T-scores, treatment is indicated. Declining T-scores indicates treatment failure on bisphosphonate therapy, so changing to a new class of medication is recommended. Therefore, Alendronate (Fosamax) and Risedronate (Actonel) would be unlikely to change her response. Dual therapy is not currently recommended and adding a second agent while continuing Zoledronic acid (Reclast) increases the risk of side effects without known benefit. Transition to an alternative class of medication with an anabolic agent or Denosumab (Prolia) is most beneficial.

Case Study #3:

Osteoarthritis: reliable LS T-score?Declining FN T-scoreAdherence is guaranteed Tx failure on bisphosphonate

High risk: Significant osteoporosis in FNHx of vertebral compression fxDeclining T-scores despite txAlternative treatment is recommended

Case Study #3:

Consider Denosumab (Prolia) Anti-resorptive Significant reduction in fx risk after 3 years

Anabolic agents: Teriparatide (Forteo), Abaloparatide (Tymlos) Significant reduction in fx risk after 18 months of therapy Risk of osteosarcoma Follow up with antiresorptive after d/c

Anabolic agent: Romosozumab (Evenity) Significant reduction in fx risk over 1 year of therapy Black Box Warning: contraindicated in MI or CVA within the last year Limited to 1 year duration of tx


Case Study #4:

59-year-old Caucasian male with a 5-year hx of COPD and former smoker Frequently on inhaled and PO steroid tx for exacerbations, most

recently within the last yearPresents with a low impact LS compression fractureCompletes first DXA scan: T-score LS -2.1, FN -2.3Calculated FRAX: 26%, 3%

Question 4 Should a 59-year-old Caucasian male with a 5-year hx of COPD and


A. Yes, all men >50 years old should be screenedB. Yes, based on his age >50 and risk factors of history of smoking and steroid useC. No, he does not currently smoke or use steroid treatmentsD. No, he is <70 years old

Question 4: Answer B Should a 59-year-old Caucasian male with a 5-year hx of COPD and


B. Yes, based on his age >50 and risk factors of history of smoking and steroid use

Rationale: Based on NOF criteria, men >50 years old with risk factors including a smoking history and steroid treatment should be screened for low bone density. His cumulative smoking history and recent steroid use are major risk factors and neither need to be current in order to screen him. Screening all men >50 or deferring all screening until men are >70 is inconsistent with the current guidelines.

Case Study #4:

Osteopenia + fragility fx + high FRAX = osteoporosisSecondary work up shows low vitamin D, otherwise WNLWould you treat Ron? With which agent?Approved agents for men: Alendronate (Fosamax), Risedronate

(Actonel), Zoledronic acid (Reclast), Denosumab (Prolia), Teriparatide (Forteo)
