21 clinicaloptions.com/oncology Optimizing Therapeutic Strategies Targeting Bone: Lung Cancer Safety and Tolerability Profile of Zoledronic Acid  > 3.5 million patients treated worldwide in clinical practice [1] –> 3000 patients treated in randomized trials  Long-term study (mean treatment duration: 3.6 yrs) demonstrated zoledronic acid was generally well tolerated [2]  Safety profile of IV bisphosphonates –Transient and manageable flulike symptoms after initial infusions –Dose- and infusion rate–dependent effects on renal function –Osteonecrosis of the jaw—lower rate in lung cancer setting compared with reports in myeloma or breast cancer [3] 1.

22 clinicaloptions.com/oncology Optimizing Therapeutic Strategies Targeting Bone: Lung Cancer IV Bisphosphonate Effects on Renal Function: Prevention and Management  Changes in kidney function are related to C max –ie, the highest level of BP is in the blood –As a result, rate of infusion is the key factor in prevention of kidney problems –Rates faster than 0.3-0.7 mg/min are associated with problems  Importantly, rate of infusion has no impact on prevention of skeletal complications –Efficacy related to AUC (how much remains in patient)  Zoledronic acid and pamidronate affect different parts of the kidney –Zoledronic acid: tubular –Pamidronate: glomerular  Reduce the risk of renal dysfunction –Monitor serum creatinine prior to each infusion –Make sure patient is hydrated at time of treatment

23 clinicaloptions.com/oncology Optimizing Therapeutic Strategies Targeting Bone: Lung Cancer Biochemical Markers of Bone Formation and Resorption  Collagen degradation –NTx (urine/serum)* –CTx  Collagen crosslinks: PYD and DPD crosslinks of type I collagen  Osteoclasts –TRAcP-5b –BSP  Liver/bone/gut: serum ALP  Osteoblasts  Maturation: serum bone-specific alkaline phosphatase  Mineralization: osteocalcin  Initiation of collagen production: serum P1NP Osteoclasts Osteoblasts Osteoid *Most commonly used for marker of resorption in clinical practice.

28 clinicaloptions.com/oncology Optimizing Therapeutic Strategies Targeting Bone: Lung Cancer Summary  In patients with cancer, increased levels of markers of bone resorption, such as urinary NTx, are associated with an increased risk of SREs, disease progression, and death  Zoledronic acid confers normalization of NTx in 81% of patients with metastatic NSCLC disease and elevated markers of bone resorption  Normalization of NTx in patients with elevated NTx at baseline reduced the risk of death from NSCLC by 48% Lipton A, et al.

37 clinicaloptions.com/oncology Optimizing Therapeutic Strategies Targeting Bone: Lung Cancer Potential Mechanisms for Improved Outcomes With Bisphosphonate Therapy Bisphosphonates  therapy options (preservation of function) Effects on cancer cells (alone or with chemo) Effects on “vicious cycle” (bone) and anticancer response  SRE-related mortality  SREs Anticancer effects Improved disease outcomes:  Delayed disease progression  Prolongs survival

38 clinicaloptions.com/oncology Optimizing Therapeutic Strategies Targeting Bone: Lung Cancer Summary  Bisphosphonates help reduce the risk of SREs in patients with bone metastases  Normalization of bone turnover markers leads to improved outcomes and longer survival in lung cancer  Zoledronic acid only bisphosphonate to show anticancer benefits across tumor types alone or combined with chemotherapy –Decreases tumor angiogenesis –Stimulates antitumor immune response –Directly decreases tumor growth, invasion, and metastasis –Induces tumor cell apoptosis
