Brief Summary:
To evaluate the best sequencing approach with the combination of target agents (LGX818 plus MEK162) and the combination of immunomodulatory antibodies (ipilimumab plus nivolumab) in patients with metastatic melanoma and BRAF V600 mutation.

Condition or disease Intervention/treatment Phase
Metastatic Melanoma Drug: LGX818 Drug: MEK162 Drug: Nivolumab Drug: Ipilimumab Phase 2

Detailed Description:

The combination BRAF (B-raf murine sarcoma viral oncogene homolog B1) inhibitor plus mitogen-activated protein kinase (MEK) inhibitor seems to be more effective in the V600 BRAF mutated advanced melanoma patients compared to treatment with the BRAF inhibitors alone. In fact, a phase I-II study showed a better overall response rate (ORR) and progression-free survival (PFS) in the combination arm (dabrafenib plus trametinib) respect to the single agent treatment (dabrafenib): 76% and 9.4 months versus 54% and 5.8 months respectively. Another phase I study with a similar combination (vemurafenib plus cobimetinib) showed an ORR of 85% in vemurafenib-naïve patients.

Recently, the results of a phase I study about the combination ipilimumab plus nivolumab have been reported. In this study at the selected schedule (ipilimumab 3 mg/kg and nivolumab 1 mg/kg), 53% of patients had an objective response, all with tumor reduction of 80% or more. Reponses were durable, although longer follow-up is needed.

A recent phase I study has shown a high rate of liver toxicity with the combo ipilimumab plus vemurafenib . which makes difficult a combination with these two different drugs. Moreover, a better efficacy of the sequencing treatment BRAF inhibitors/ipilimumab vs. the single agent treatment was also observed; for this reason it was also suggested to start immunotherapy treatment in the BRAF V600 mutated melanoma population as first option, in order to increase the percentage of patients who can benefit from the sequencing, considering the possibility of a fast progression of the disease after the BRAF inhibitors treatment.

Taking into account these considerations, it seems impossible to think to combine all the four compounds (the target agents and immunomodulating monoclonal antibodies). The risk of a high rate of toxicity is realistic and would render this approach inapplicable.

Sequencing with these different combinations seems to be more feasible. However, also in this case it would be important to start with the best combination in order to give to the patients the best chance to increase the overall survival.

The aim of this prospective randomized phase II study is to evaluate the sequencing of these two different combinations and evaluate which is the best of these approaches.

Primary Outcome Measures :
  1. Overall Survival [ Time Frame: Patients enrolled will receive study medication until disease progression, unaccettable toxicity, withdrawal of consent or death, whichever comes first, assested up to 24 month ]
    OS is defined as the time between the date of randomization and the date of death due to any cause. OS will be censored on the last date a subject was known to be alive. OS data will be collected continuously while subjects are on study medication and every 3 months via in-person or phone contact after discontinuation of study medication


Secondary Outcome Measures :
  1. Total Progression free survival [ Time Frame: Baseline (Day 1), every 6 weeks until second disease progression is documented (Approximately around 2 years) ]

    PFS is defined as the time between the date of randomization and the first date of documented progression, as determined by the investigator, or death due to any cause, whichever occurs first.

    Tumor responses will be assessed by the Investigator according to RECIST Criteria (version 1.1)


  2. Percentage of patients alive at 2 and 3 years; [ Time Frame: Time Frame: at 24^ and 36^ month ]
    Percentage of patients alive at 2 and 3 years will be reported using Wilson score intervals.

  3. Best overall response rate (BORR); [ Time Frame: Time Frame: up to 24 months ]
    It will be calculated as the percentage of ITT population patients who have a CR o o PR before any evidence of progression (as defined by RECIST).

  4. Duration of response (DoR); [ Time Frame: Time Frame: up to 24 months ]
    It will be calculated as the percentage of ITT population patients who have a CR o o PR before any evidence of progression (as defined by RECIST).

  5. Toxicity of the investigational medicinal products (IMPs). [ Time Frame: Time Frame: up to 24 months ]
    Safety and tolerability will be assessed in terms od AEs, laboratory data, ECG data, vitals signs and weight, which will be collected for all patients. AEs (both in terms od MedDRA preferred terms and CTCAE grade), laboratory data, ECG data, vital signs and weight will be listes individually by patient and summarized by treatment received. ECG changes will be summarized for each treatment group.

  6. Quality of life and general health [ Time Frame: Time Frame: up to 24 months ]
    Changes from baseline in EQ-5D and QLQ-C30 total score will be summarized by means of descriptive statistical methods.

  7. 3 years PFS rate [ Time Frame: Time Frame: up to 36 months ]
    3 years PFS rate; calculated from the date of randomization;
