Study information
Scientific title
A double-blind randomised controlled trial (RCT) to assess the feasibility of giving Zoledronic acid alongside chemotherapy in patients with mesothelioma to design a larger trial to assess the efficacy of Zoledronic acid alongside first line chemotherapy
Acronym
ZOL-A
Study hypothesis
The aim of this study is to investigate the feasibility of running a trial to establish the role of zoledronic acid (ZA) in patients who have mesothelioma and are undergoing or eligible for chemotherapy.

Condition
Specialty: Respiratory disorders, Primary sub-specialty: Respiratory disorders; UKCRC code/ Disease: Cancer/ Malignant neoplasms of respiratory and intrathoracic organs
Intervention
Patients will be randomised using varying block sizes on a 1:1 to one of two groups using web based software developed by Sealed Envelope. Randomisation will be stratified according to histological subtype. Participants will be allocated to either the IMP (Zoledronic acid) or placebo arms.
Participants in both arms of the trial will receive the infusion on the day of their chemotherapy, just prior to start of their chemotherapy treatment. They will have the same number of cycles of the IMP/placebo, as chemotherapy. Those who stop chemotherapy treatment early will stop IMP/placebo treatment too.
A renally adjusted dose of Zoledronic acid or placebo will be administered in 100ml of 0.9% saline via an intravenous cannula over 15 minutes alongside each session of chemotherapy (every 3 weeks, up to a maximum of 6 cycles). Randomised patients will be stratified by histological subtype and allocated to either Zoledronic acid or placebo. A third non-randomised arm of the trial is available to patients who decline chemotherapy but would like an opportunity to have Zoledronic acid on its own (every 3 weeks, up to a maximum of 6 cycles).
Follow up will occur after each cycle, at end of treatment and at 6 months, and involves information gathering on any AEs or SAEs relating to the IMP. Participants will also have blood tests at their follow-up appointments to ensure they are able to continue with the next cycle of chemotherapy treatment/IMP or placebo.

Primary outcome measure
1. Recruitment rate is recorded as the number of eligible participant who consent to participate in the study by 6 months
2. Acceptability of recruitment procedures, consent and randomisation, and data collection methods are measured through patient interviews conducted at 6 months
3. Tolerance of the IMP treatment will be measured by the proportion of patients who complete the full 6 cycles of treatment
4. Intolerance will be recorded for those who are unable to continue to with the IMP due to electrolyte disturbances or AEs relating to the IMP and come off treatment before completing 6 cycles
5. Efficacy data will be measured using CT scans, PET-CT scans and Mesothelin bloods tests. On CT a > 15% reduction in the modified RECIST score would be classed as a disease response. CT will be performed at post 3 cycles and at 6 months from enrolment
