Reason for request

New indication

Key points

Approval of reimbursement in the treatment of patients aged 12 years and older with acute graft-versus-host disease or chronic graft-versus-host disease who have an inadequate response (resistant or dependent) to corticosteroids or other systemic therapies.

Therapeutic improvement?

A therapeutic advance in the management of patients with acute graft-versus-host disease or chronic graft-versus-host disease who have an inadequate response (resistant or dependent) to corticosteroids or other systemic therapies.

Role in therapeutic strategy?

The therapeutic management of GvHD is currently based on systemic treatment with corticosteroids for acute grade II to IV GvHD and for moderate to severe chronic GvHD, due to the hyper-inflammatory state of the patient. Apart from corticosteroids, which are used as the first-line treatment in a curative context, but for which approximately one in two patients are refractory, there is currently no single established and consensual therapeutic strategy for the treatment and management of these diseases, despite the existing therapeutic alternatives.

The European Society for Blood and Marrow Transplantation (EBMT) European guidelines, updated in 2020, indicate that there is no standard second-line treatment for acute or chronic drug-resistant GvHD.

Role of the medicinal product

JAKAVI (ruxolitinib) is a first-line treatment in the management strategy for patients aged 12 years and older with acute graft-versus-host disease or chronic graft-versus-host disease who have an inadequate response to corticosteroids or other systemic therapies.

The Summary of Product Characteristics (SPC) and the Risk Management Plan (RMP) must be followed.

Special recommendations

The Committee would like to receive the final overall survival data from the REACH 3 study as soon as it is available. On the basis of these results, it  will decide whether to reassess this medicine.


Clinical Benefit

Substantial

The Committee deems that the actual clinical benefit of JAKAVI (ruxolitinib) is SUBSTANTIAL in the marketing authorisation indication.


Clinical Added Value

minor

Considering:

  • the new means of management provided by JAKAVI (ruxolitinib),
  • the simplicity of its administration due to its tablet form (oral route), enabling the product to be used on an outpatient basis,
  • the results of the available clinical studies supporting the presumption of a benefit for the patient, including
    • short-term efficacy data from a randomised, open-label, comparative phase III study that demonstrated the superiority of ruxolitinib over comparator therapies for the 28-day overall response rate (OR=2.64 [95% CI: 1.65-4.22]) and 56-day overall response rate (OR=2.38 [95% CI: 1.43-3.94]) in patients over 12 years of age with grade II-IV corticosteroid-resistant acute GVHD (REACH 2 study),
    • efficacy data from a phase III, comparative, randomised, multi-centre, open-label study that demonstrated the superiority of ruxolitinib for the 24-week overall response rate (OR=2.99 [95% CI: 1.86-4.80]) and survival without treatment failure (HR=0.37 [95% CI: 0.27-0.51]) in patients over 12 years of age with moderate to severe corticosteroid-refractory or corticosteroid-dependent chronic GVHD (REACH study 3),
  • the medical need for effective medicines to treat patients with acute or chronic graft-versus-host disease who have an inadequate response to corticosteroids or other systemic therapies,
  • the known acceptable safety profile of ruxolitinib with a majority of haematological adverse events related to its mechanism of action,

and despite:

  • the lack of robust evidence of an effect on overall survival assessed on an exploratory basis in life-threatening clinical situations,
  • the low number of adolescent patients aged 12 to 18 years included (approximately 3% in each study), which does not ensure the transposability of the results of the clinical studies in this population,

the Committee deems that JAKAVI (ruxolitinib) provides minor clinical added value (CAV IV) in the therapeutic strategy.

 

 

 


Avis économique

Ce produit a fait l'objet d'un avis économique rendu par la Commission d'évaluation économique et de santé publique le 22/11/2022. L’avis économique porte sur une indication superposable à celle demandée au remboursement, à savoir les patients âgés de 12 ans et plus atteints de la maladie du greffon contre l’hôte aiguë ou la maladie du greffon contre l’hôte chronique qui ont une réponse inadéquate (résistants ou dépendants) aux corticostéroïdes ou à d’autres traitements systémiques. 

La CEESP conclut que :  

  • dans la maladie du greffon contre l’hôte aiguë en cas de réponse inadéquate aux corticostéroïdes ou à d’autres traitements systémiques : 
    • JAKAVI est dominant versus les meilleurs traitements disponibles sur un horizon temporel de 5 ans dans la maladie ; 
    • l’économie générée est principalement portée par les économies réalisées au travers du suivi de la maladie, supposant notamment une hospitalisation complète des patients non-répondeurs ; 
    • l’incertitude globale associée à l’estimation des résultats, en partie explorée au travers des analyses de sensibilité conduites, est forte.  
  • dans la maladie du greffon contre l’hôte chronique en cas de réponse inadéquate aux corticostéroïdes ou à d’autres traitements systémiques :
    • JAKAVI est associé à un RDCR de 66 365 € par QALY gagné versus les meilleurs traitements disponibles sur un horizon temporel de 5 ans. Ce RDCR est toutefois probablement sous-estimé en raison notamment du choix favorable et non-étayé d’intégrer les traitements ultérieurs pour les patients non-répondeurs ;  
    • l’incertitude globale associée à l’estimation des résultats, en partie explorée au travers des analyses de sensibilité conduites, est forte.

L’impact budgétaire total associé à l’introduction du ruxolitinib représente une augmentation des dépenses de l’assurance maladie dans l’indication de 0,5%, pour une population cible de 3 819 patients cumulés sur 5 ans.
