Reason for request

New indication

Key points

Favourable opinion for reimbursement as monotherapy for the first-line maintenance treatment of adult patients with locally advanced or metastatic urothelial carcinoma (UC) who are progression-free following platinum-based chemotherapy.

What therapeutic improvement?

Therapeutic improvement compared to supportive care.

Role in the care pathway?

The first-line treatment of urothelial carcinoma is founded on platinum-based polychemotherapy regimens. Cisplatin eligible patients may receive: gemcitabine + cisplatin, methotrexate + vinblastine + adriamycin + cisplatin, or paclitaxel + cisplatin + gemcitabine. For cisplatin ineligible patients, carboplatin-based chemotherapy is recommended.

For patients who are progression-free following their first-line platinum-based chemotherapy, there is no recommended maintenance treatment.

Role of the medicinal product in the care pathway

Considering the demonstration of a clinically relevant benefit in combination with supportive care compared to supportive care alone, in terms of overall survival, the Transparency Committee deems that BAVENCIO (avelumab), as monotherapy, is a first-line maintenance treatment in adult patients with locally advanced or metastatic urothelial carcinoma (UC) who are progression-free following platinum-based chemotherapy. It should be noted that in the clinical study, patients had received cisplatin or carboplatin combined with gemcitabine. Uncertainty persists with respect to the level of efficacy in patients having received first-line MVAC (methotrexate, vinblastine, adriamycin, cisplatin) or paclitaxel + cisplatin + gemcitabine chemotherapy, since no patients included in the study had been treated with these protocols.


Clinical Benefit

Substantial

The Committee deems that the clinical benefit of BAVENCIO (avelumab) is substantial in the MA indication.


Clinical Added Value

moderate

Considering:

  • demonstration of the superiority of BAVENCIO (avelumab), as monotherapy, compared to supportive care, in terms of overall survival (HR=0.69 [CI%: 0.54-0.92], with an individual estimate of an absolute improvement of 7.1 months, deemed clinically relevant), in anopen-label, randomised phase 3 study and,
  •  the substantial medical need in the absence of alternatives in this indication,

and despite:

  • the onset of grade ≥ 3 adverse events in one in two patients,
  • a mainly immunological toxicity and infusion-related reactions (important identified risks
    according to the RMP),
  • the lack of demonstrated impact on quality of life,

The Transparency Committee considers that BAVENCIO (avelumab), as monotherapy, provides moderate clinical added value (CAV III) compared to supportive care, in first-linemaintenance treatment in adult patients with locally advanced or metastatic urothelial carcinoma (UC) who are progression-free following platinum-based chemotherapy.


Avis économique

Ce produit a fait l'objet d'un avis économique validé par la Commission d'évaluation économique et de santé publique le 26 octobre 2021. L’indication du produit porte sur la population des patients adultes atteints de carcinome urothélial à un stade localement avancé ou métastatique, dont la maladie n’a pas progressé après la chimiothérapie à base de platine.

La CEESP a été en mesure de conclure sur le niveau d’efficience du produit, avec un ratio différentiel coût-résultat (RDCR)  de 188 451 €/QALY versus les soins de support sur un horizon temporel limité à 10 ans. l’incertitude associée à ce RDCR provient majoritairement de l’extrapolation de la survie globale et de la fragilité de la méthode d’estimation des utilités en post- progression compte tenu du manque de données.

L’introduction d’avélumab conduit à une augmentation de +167% du budget de l’assurance maladie consacré à cette indication.
