Brief Summary:
Treatment of higher-risk intermediate high and very high Myelodysplastic Syndromes MDS according to the revised International Prognostic Scoring System IPSS-R who obtained a stable hematological response CR PR after subcutaneous azacitidine treatment
Azacitidine is administered in hospital in a day care regimen in Italy only by subcutaneous injection The long duration of therapy obliges patients to travel to the hospital regularly with evident worsening quality of life both for patients and caregivers although balanced by prolongation of survival and hematological improvement Many patients stop therapy or are reluctant to continue because of the dependence from caregivers and hospital care
This clinical study will evaluate the efficacy and safety of oral azacitidine CC-486 plus best supportive care in subjects with higher-risk intermediate high and very high Myelodysplastic Syndrome MDS according to the revised International Prognostic Scoring System IPSS-R and high and INT-2 according to IPSS who obtained a stable hematological response CR PR SD with HI after at least 4-6 cycles of subcutaneous azacitidine treatment and maintained for 2 additional cycles

Detailed Description:
Azacitidine therapy is effective in prolonging survival in higher risk MDS patients provided therapy is administered at 28 day-cycles until progression or loss of response
A study conducted several years ago shows that although most responses to azacitidine occurred within 6 cycles continued azacitidine therapy led to a further improvement in response category in almost half 48 of all responders with a median of 3 additional cycles and that 92 of patients achieved their best response by Cycle 12 In a randomized phase 3 trial conducted by the US Cancer and Leukemia Group B which compared azacitidine with best supportive care most responses occurred during the third or fourth month of azacitidine therapy The phase 3 Cancer and Leukemia Group B study also showed that 90 of responses occurred within the first 6 cycles of treatment and that best response generally occurred 2 cycles after the first response-all of which is consistent with the current findings Taken together these data suggest that although some effects of azacitidine manifest promptly additional courses are usually necessary before best response is achieved Therefore continuing azacitidine therapy offers the best chance of enhanced benefit if treatment is tolerated and there is no evidence of disease progression
Azacitidine may affect the differentiation and growth of the MDS clone without necessarily eradicating it suggesting that repetitive and prolonged exposure to azacitidine may be necessary for both the initial effects and the subsequent augmentation of response Discontinuation of azacitidine therapy is in fact invariably followed by loss of response disease progression and short survival Treatment should be optimized to deliver at least 6 cycles and in responsive patients until progression In clinical practice however AZA is often discontinued after few cycles Prematurely interrupted therapy could be the cause of inferior outcomes registered in real life studies This inconsistency may be due to differences in adherence to dose schedule and minimum number of cycles as well as to the management of patients with severe comorbidities Proper management of first-line azacitidine therapy with appropriate doses and prolonged treatment may partially reduce primary resistance This is why it is extremely important to maintain treatment until progression despite scarce compliance of the patients to subcutaneous injections Anyhow it is clear that the azacitidine effect is transient with responses maintained for 6 to 24 months
Survival of the patients with refractoryrelapsed disease is extremely short A premature arrest of treatment may thus provoke loss of response and accelerate progression In order to improve the compliance to treatment of MDS patients who have shown optimal responses to azacitidine an oral formulation of the drug could indeed be advantageous Oral therapy with CC 486 could free patients from hospital and caregiver dependence as well as from injection site reactions consequently improving quality of life without altering the necessary continuation of treatment During the present Covid-19 outbreak it has became even clearer that treatment with medications in oral formulation under strict control of treating physicians may indeed beyond improving quality of life decrease the risk of exposure to infections derived by in hospital administered therapy for MDS patients
An oral formulation of azacitidine like cc486 provides an opportunity to deliver the drug at lower systemic doses over a more prolonged schedule that can be practically achieved with parenteral therapy In addition an oral formulation that can be taken at home rather than in the hospitalclinic setting represents an opportunity for patients with MDS to have a more convenient route of administration thus alleviating the morbidity of injection and avoiding the inconvenience and resource utilization costs associated with frequent hospitalclinic visits In addition intervention with azacitidine in patients with MDS that have obtained a response after sc azacitidine may offer better quality of life and possibly a survival advantage
