ORIGINAL RESEARCH ARTICLE Bioequivalence Study of Two Formulations of Ibandronic Acid 150-mg Film-Coated Tablets in Healthy Volunteers Under Fasting Conditions: A Randomized, Open-Label, Three-Way, Reference-Replicated Crossover Study
2014Co-Authors: Augusto Filipe, Pedro Pedroso, Rita Neves, Susana Almeida, Sylvie BoudreaultAbstract:The Author(s) 2014. This article is published with open access at Springerlink.com Aims This bioequivalence study aimed to compare rate and extent of absorption of a generic medicinal product of Ibandronic Acid 150-mg film-coated tablet versus Bonviva. Methods This was a single-centre, open-label, random-ized, three-way, three-sequence, reference-replicated, crossover bioequivalence study, under fasting conditions. A single oral dose of Ibandronic Acid as one 150-mg film-coated tablet was administered in each study period. Each washout period lasted 14 days. Blood samples were col-lected according to a predefined sampling schedule and up to 48.0 hours after administraton in each period. Plasma concentrations of Ibandronic Acid were measured using a liquid chromatograph–mass spectrometry/mass spectrom-etry method. Bioequivalence between generic and refer-ence medicinal products is acceptable if the 90 % confidence intervals (CI) of ratio of least-squares means between the test and the reference product of ln-trans-formed area under the serum concentration–time curve from time zero to time of last measurable concentration (AUC0–t) is within the 80.00–125.00 % interval. Prospec-tively, a scaled average bioequivalence approach for maximum serum concentration (Cmax) was established. Results 153 healthy volunteers were enrolled and ran-domized. After the test formulation (T) and first and second Bonviva (R) dosing, the Cmax was 96.71 ± 90.19 ng/mL, 92.67 ± 91.48 ng/mL and 87.94 ± 60.20 ng/mL and the AUC0–t was 390.83 ± 287.27 ngh/mL, 388.54 ± 356.76 ngh/mL and 383.53 ± 246.72, respectively.

oral Ibandronic Acid versus intravenous zoledronic Acid in treatment of bone metastases from breast cancer a randomised open label non inferiority phase 3 trial
Lancet Oncology, 2014Co-Authors: Peter Barrettlee, Angela C Casbard, J Abraham, Kerenza Hood, Robert E Coleman, Peter Simmonds, Hayley Timmins, Duncan Wheatley, Robert Grieve, Gareth GriffithsAbstract:Summary Background Bisphosphonates are routinely used in the treatment of metastatic bone disease from breast cancer to reduce pain and bone destruction. Zoledronic Acid given by intravenous infusion has been widely used, but places a substantial logistical burden on both patient and hospital. As a result, the use of oral Ibandronic Acid has increased, despite the absence of comparative data. In the ZICE trial, we compared oral Ibandronic Acid with intravenous zoledronic Acid for the treatment of metastatic breast cancer to bone. Methods This phase 3, open-label, parallel group active-controlled, multicentre, randomised, non-inferiority phase 3 study was done in 99 UK hospitals. Eligibility criteria included at least one radiologically confirmed bone metastasis from a histologically confirmed breast cancer. Patients with ECOG performance status 0 to 2 and clinical decision to treat with bisphosphonates within 3 months of randomisation were randomly assigned to receive 96 weeks of treatment with either intravenous zoledronic Acid at 4 mg every 3–4 weeks or oral Ibandronic Acid 50 mg daily. Randomisation (1:1) was done via a central computerised system within stratified block sizes of four. Randomisation was stratified on whether patients had current or planned treatment with chemotherapy; current or planned treatment with hormone therapy; and whether they had a previous skeletal-related event within the last 3 months or had planned radiotherapy treatment to the bone or planned orthopaedic surgery due to bone metastases. The primary non-inferiority endpoint was the frequency and timing of skeletal-related events over 96 weeks, analysed using a per-protocol analysis. All active (non-withdrawn) patients have now reached the 96-week timepoint and the trial is now in long-term follow-up. The trial is registered with ClinicalTrials.gov, number NCT00326820. Findings Between Jan 13, 2006, and Oct 4, 2010, 705 patients were randomly assigned to receive Ibandronic Acid and 699 to receive zoledronic Acid; three patients withdrew immediately after randomisation. The per-protocol analysis included 654 patients in the Ibandronic Acid group and 672 in the zoledronic Acid group. Annual rates of skeletal-related events were 0·499 (95% CI 0·454–0·549) with Ibandronic Acid and 0·435 (0·393–0·480) with zoledronic Acid; the rate ratio for skeletal-related events was 1·148 (95% CI 0·967–1·362). The upper CI was greater than the margin of non-inferiority of 1·08; therefore, we could not reject the null hypothesis that Ibandronic Acid was inferior to zoledronic Acid. More patients in the zoledronic Acid group had renal toxic effects than in the Ibandronic Acid group (226 [32%] of 697 vs 172 [24%] of 704) but rates of osteonecrosis of the jaw were low in both groups (nine [1%] of 697 vs five [ vs 98 [14%] of 704 allocated Ibandronic Acid), increased bone pain (91 [13%] vs 85 [12%]), joint pain (41 [6%] vs 38 [5%]), infection (31 [5%] vs 23 [3%]), and nausea or vomiting (38 [5%] vs 41 [6%]). Interpretation Our results suggest that zoledronic Acid is preferable to Ibandronic Acid in preventing skeletal-related events caused by bone metastases. However, both drugs have acceptable side-effect profiles and the oral formulation is more convenient, and could still be considered if the patient has a strong preference or if difficulties occur with intravenous infusions.
