Brief Summary:
Phase II, multicenter, single arm trial to assess the feasibility of first line ribociclib in combination with a non steroidal aromatase inhibitor in women or men aged 70 years-old or older, with hormone receptor positive/HER2 negative advanced breast cancer

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: Ribociclib Drug: Aromatase Inhibitors, non steroideal Drug: LHRH agonist Phase 2

Detailed Description:

Elderly patients are generally more susceptible to the side effects of active treatments. Patients entered in clinical trials, especially the elderly, are not completely representative of the "real" population because of selection process. The lack of data collected from a real population turns the indication of treatment a challenging task and expose older patients to a risk of under treatment (fear of excessive toxicity because of the lack of data).

With the aim of covering this gap, we are planning to run a phase II trial evaluating the feasibility of delivering the combination of ribociclib plus NSAI as first-line treatment specifically in a population of breast cancer patients aged ≥70 years.

Primary endpoint:

• The treatment feasibility will be evaluated as the proportion of patients not having experienced disease progression (PD), still on treatment with ribociclib plus NSAI 6 months after the first drug administration

Secondary endpoints:

  • Treatment adherence
  • Safety and tolerability
  • Patient reported outcomes (PROs)
  • Overall response rate (ORR)
  • Progression free survival (PFS)

Drug Information available for: Ribociclib

Arm Intervention/treatment
Experimental: single arm

patients will receive anastrozole tablets (1 mg once daily) or letrozole tablets (2.5 mg once daily) + ribociclib tablets (600 mg day 1 to 21 in a 28 day cycle).

  6. Number of comorbities (impact on study inclusion) [ Time Frame: 30 months ]
    Number of comorbidities and relative grading will be collected using Cumulative Illness Rating Scale- Geriatric (CIRS-G) (for patients not included into the study due to comorbities).SCORE: 0- No problem , 1- Current mild problem or past significant problem, 2- Moderate disability or morbidity/requires first line therapy, 3- Severe/ constant significant disability/ uncontrollable chronic problems, 4- Extremely severe/ immediate treatment required/ end organ failure/ severe impairment in function
