Efficacy and Safety of Systemic Treatments of Bone Metastases From Kidney Cancer in Patients Treated With Targeted Therapies

Phase 3
Terminated
Conditions
Metastatic Renal Cell Carcinoma
Interventions
Registration Number
NCT03408652
Lead Sponsor
Centre Leon Berard
Brief Summary

Multicenter, randomized, open-label, 2-arm, parallel-group, phase III study whose goal is to assess the efficacy and safety profile of bone-targeted treatments (Arm A: denosumab or zoledronic acid) versus the control arm (Arm B: no specific treatment) in patients with bone metastases under targeted therapy for Metastatic Renal Cell Carcinoma.

Inclusion Criteria
  • Age ≥ 18 years.
  • Histologically proven mRCC.
  • Administration of one of the systemic agents in use for the treatment of mRCC (no more than three prior systemic therapy regimens). Patients with at least 6 months of 1st line treatment and a bone event may be included.
  • More than 1 bone metastasis.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) ≤ 2.
  • Adequate renal function (serum creatinine ≤ 200 mmol/L or creatinine clearance ≥ 30 mL/min according to Cockroft formula or MDRD formula for patients older than 65 years).
  • Covered by a medical insurance.
  • Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures.
  • Signed informed consent.
  • Accepting to use effective contraception during study treatment and within 5 months after final dose of study therapy.
Exclusion Criteria
  • Prior bisphosphonate or denosumab treatment in the year before inclusion.
  • Imminent or ongoing nerve or spinal compression as per the investigator's judgement.
  • Ongoing first-line therapy, started for less than 6 months (patients with BM at time of metastases diagnosis will initially benefit from the angiogenesis targeted agents used and are not at higher risk).
  • Anticancer treatment under investigation.
  • Paraneoplastic hypercalcemia (corrected total calcium > 2.7 mmol/L).
  • Grade 4 toxicity under previous targeted agents.
  • Liver failure (AST and/or ALT ≥ 5.0 x upper limit of normal (ULN) or total bilirubin beyond normal limits).
  • Severe hypocalcaemia > 2.8 mmol/l.
  • Fructose intolerance.
  • Invasive dental procedure (i.e. tooth extraction, dental implants, oral surgery) within the 10 days prior to randomization or required dental procedures at the pre-inclusion dental examination.
  • Psychological, familial, sociological, geographical conditions that would limit compliance with study protocol requirements.
  • Pregnant or breastfeeding woman. Females of child-bearing potential must have a negative serum pregnancy test within 7 days prior inclusion.
  • Life expectancy ≤ 3 months.
  • Participation to another clinical trial that might interfere with the evaluation of the main criterion.
  • Known hypersensitivity to the active substance or to any of the excipients of bisphosphonate or denosumab.

Primary Outcome Measures
NameTimeMethod
Time to first Skeletal Related EventUp to 54 months after the first inclusion

Defined as the time from randomization to first SRE. Patients without event will be censored at the time of the last clinical evaluation.

Secondary Outcome Measures
NameTimeMethod
Evolution of painEvery 3 months until the 18th month for each patient

Proportion of patients that shifted from not taking a strong opioid at baseline

Number of specific event-free survivalsUp to 54 months after the first inclusion

Specific times from randomization to appearance of the first Skeletal Related Event.

Overall survivalUp to 54 months after the first inclusion

Measured from the date of randomization to the date of death from any cause

Cost-effectiveness analysesUp to 18 months for each patient

All the hospitalization costs will be collected during the timeframe: outpatient, inpatient, and home care

Budget impact analysisUp to 18 months for each patient

Quantification of financial consequences of rolling out this kind of medical supportive care strategy throughout the health system.

Number of participants with treatment-related adverse events as assessed by CTCAE v4.0Every 3 months until the 18th month for each patient

Incidence of adverse events (AEs) assessed using the National Cancer Institute - Common Terminology Criteria for Adverse Event (NCI-CTCAE) v4 grading scale, specific registration of ONJ or other osteonecrosis and rate of skeletal event per patient during study duration

Evolution of pain severityEvery 3 months until the 18th month for each patient

Proportion of patients with a clinically meaningful change in pain severity evaluated using a numerical rating scale (NRS)

Patient's condition evaluationUp to 18 months for each patient (evaluated at baseline, months 3, 6, 9 and 18)

"EuroQoL 5 Dimensions 5 Levels" questionnaire is a scale used in the health state description. Each items is a three-level scale : having no problems, having some or moderate problems, being unable to do/having extreme problems.The respondents are asked to choose one of the statements which best describes their health status of surveyed day. Rated level can be coded as a number 1, 2, or 3, which indicates having no problems for 1, having some problems for 2, and having extreme problems for 3. As a result, a person's health status can be defined by a 5-digit number, ranging from 11111 (having no problems in all dimensions) to 33333 (having extreme problems in all dimensions).

Cost-utility analysisUp to 18 months for each patient

All the hospitalization costs will be collected during the timeframe: outpatient, inpatient, and home care

Evaluation of the different practices for bone metastases treatmentsUp to 18 months for each patient

Financial evaluation of centers' practices (home or hospitalization)
