PP126 MEA In Italy: Correlation Between Time To Payment By Result And Time To Off Treatment Curve

Abstract

INTRODUCTION:

Payment by result agreements have been quite widely used in Italy to provide access for high costs oncologic drugs and minimize uncertainties of real life benefits (1). The aim of this analysis was to overview the Roche experience in terms of Payment by Result (Pbr) in oncology and investigate the relation between timing for the evaluation of treatment failures and observed Time to Off Treatment (TTOT) from Phase III clinical trials (2).

METHODS:

A retrospective analysis of the Roche payment by results schemes in place in Italy was conducted. For each drug included in the analysis it was collected: (i) the negotiated timing to assess the treatment failure for payment by result, (ii) the median time to off treatment curve observed in clinical trials for the experimental drug, (iii) the median time to off treatment observed in clinical trials for the control arm. The mean ratios between timing to assess the treatment failure for payment by result and the time to off treatment observed for the experimental drug or the median time to off treatment observed in the control arm were calculated to identify potential correlations. High level of correlation was expected if ratio was close to 1 (±.2).

RESULTS:

Roche products or different indications of the same product were identified as candidates for the analysis from 2008 to 2016. The timing for the evaluation of treatment failures for Pbr varies between 2 and 9 months, depending on the type of tumor and line of therapy. The mean Time to Payment By Result (TTPbr) / Control arm Time To Off Treatment (cTTOT) ratio was 1.16 (±.37) while the mean Time to Payment By Result (TTPbr) / Experimental arm Time To Off Treatment (eTTOT) ratio was .71 (±.13). Data analysis according to different time periods shows that the mean TTPbr/cTTOT and TTPbr/eTTOT for drugs negotiated from 2008 to 2015 were respectively 1.07 and 1.39 whereas for drugs negotiated in 2016 were respectively and .63 and 1.

CONCLUSIONS:

Good level of correlation between TTPbr and cTTOT was found. This finding is in line with the methodology used by Italian Medicines Agency so far, leveraging the cTTOT as the most appropriate proxy to assess any incremental effect of a new drug compared to the previous Standard of Care. The analysis over time of TTPbr shows that in the first years of payment by result negotiation TTPbr is more correlated to the cTTOT whereas in the last years is moving closer to the experimental one.
