JAVLOR Association Study in CDDP-unfit Patients With Advanced Transitional Cell Carcinoma: Gemcitabine Versus Carboplatin

Pierre Fabre Medicament69 enrolled

Overview

This study is assessing the combination of well known cytotoxics with a novel anti-cancer agent that could be administered as monotherapy without renal toxicity in patients with renal impairment presenting with advanced or metastatic urothelial carcinoma previously treated with a platinum-based regimen. The intent of this study is to clarify the benefit/risk ratio of the two most promising associations of cytotoxics including the novel therapeutic agent, vinflunine: vinflunine-gemcitabine and vinflunine-carboplatin.

Gemcitabine and carboplatin have been the most studied and used anticancer agents in cisplatin-unfit patients with advanced urothelial carcinoma. Both agents previously demonstrated clinical activity as single agent and/or as part of combination regimen in patients with advanced or metastatic disease even if clinical benefits and survival remains limited in this setting for this population. The purpose of this study is to test in a randomized trial enrolling patients with renal impairment or moderate congestive heart failure two combinations of a novel cytotoxic agent, vinflunine, one with gemcitabine and another with carboplatin in order to determine the most promising combination in the first line treatment of advanced/metastatic urothelial carcinoma.

Outcomes

Primary Outcomes

Disease control rate as defined by RECIST criteria (version 1.1) as a percentage of best overall responses of Complete (CR) + Partial (PR) + Stable Disease (SD) for both Vinflunine-Gemcitabine and Vinflunine-Carboplatin combinations

Assessment of lesions (measurable and non-measurable) should be performed at baseline and every 6 weeks (assessment interval). Evaluable patients: all baseline lesions must have been assessed at least once after the second cycle (6 weeks); patients who progress before the first evaluation will be considered as early progression. Primary analysis is planned on the intent to treat population, secondary analysis being performed on the evaluable population.

Time frame: Change from baseline in tumor assessment at 12 weeks (cycle 4)

Secondary Outcomes

Tumor Response Rate as defined by RECIST criteria (version 1.1) with a best response as Complete (CR) or Partial (PR)

Time frame: Change from baseline in tumor assessment at 12 weeks (cycle 4)

Duration of Disease control in Participants With Best Response of CR + PR + SD

Tumor assessment at baseline and then every 6 weeks, until tumor progression. Duration of disease control according to investigator will be calculated among the responders and stable patients from the date of randomisation until the documentation of progression or death due to any cause. Patients who are lost to follow-up without progression, or reach the time point of analysis without a known record of progression or death will have the duration of disease control censored at the date of last tumour assessment or last contact of a follow-up showing no progression, whichever occur last.

Time frame: From the date of randomisation until the date of documented progression or date of death due to any cause, assessed up to 10 months

Duration of Response in Participants With Best Response of CR or PR

Tumor assessment at baseline and then every 6 weeks, until tumor progression. Duration of response will be calculated among the responders (i.e. CR and PR) . Patients who are lost to follow-up, or reach the time point of analysis without a known record of progression or death will have the duration of response censored at the date of last tumour assessment or last contact of a follow-up showing no progression, whichever occur last.

Time frame: From the date that measurement criteria are first met for complete or partial response until the date of documented progression or date of death due to any cause, assessed up to 10 months

Time to First Response calculated among the responders

Tumor assessment at baseline and then every 6 weeks. Will be calculated among the responders (i.e. CR and PR)

Time frame: From the date of randomisation up to the first report of documented response, assessed up to 12 weeks (cycle 4).

Time to Treatment Failure

Tumor assessment (RECIST) every 6 weeks. Patients who reach the time point of analysis without failure as defined above will have the time to treatment failure censored at the date of last tumour assessment or last contact of a follow-up not showing progression. Patients who discontinued treatment for other reason and who are lost to follow-up will be censored at the date of last contact.

Time frame: From the date of randomisation until tumor progression, unacceptable toxicity, withdrawal of patient consent, lost to follow-up or start of new anticancer therapy, assessed up to 10 months.

Progression Free Survival

Tumor assessment every 6 weeks (RECIST).Patients who are lost to follow-up, or reach the time point of analysis without a known record of progression or death will have the progression-free survival censored at the date of last tumour assessment or last contact of a follow-up showing no progression, whichever occur last.

Time frame: From the date of randomisation until the date of progression or the date of death from any cause if no progression was recorded before, median patient follow-up of 11 months

Overall Survival

Data recording every 3 months. For patients who have not died, survival time will be censored at the date of last news (i.e: date of last administration, tumor assessment, clinical examination, haematological or biochemistrical assessment or date of last contact).

Time frame: From the time of randomisation up to death or last follow-up, assessed with a median patient follow-up of 15 months (assessed up to 24 months)

Number of Participants With Serious Adverse Events (SAEs), Adverse Events (AEs) and AEs Leading to Discontinuation

Population: all treated patients unless the patient is lost to follow-up immediately after the start of the treatment. The patients will be analysed in the treatment arm they actually received. The NCI-CTC classification version 2.0 will be used to classify toxicities. Maximum grade or severity will be reported by cycle and by patient for each MedDRA Preferred Term. Analyses will be performed both regardless the relationship to treatment and related to treatment. Biochemical toxicities: the worst CTCAE version 2.0 grade will be analysed according to the grade present at baseline.

Time frame: AE and SAE will be collected up to 30 days after the last treatment administration, on an expected average period of 17 weeks
