An Open-Label, Phase 1, Dose Escalation Study of MLN2480 in Patients With Relapsed or Refractory Solid Tumors Followed by a Dose Expansion Phase in Patients With Metastatic Melanoma

Dose Escalation Phase: Number of Participants With Dose-limiting Adverse Events (AEs)

Time Frame: Cycle 1 (Cycle length= 22 days [Q2D] and 28 days [QW])

Dose limiting AEs were evaluated according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03. Dose limiting AEs were defined as any of the following events: Grade 4 neutropenia for more than 7 days under maximum supportive therapy; febrile neutropenia; platelet counts decreased of Grade 3 requiring platelet transfusion or blood platelet decreased of Grade 4; if Course 2 was not initiated within 14 days due to AE related to the protocol treatment; Grade 3 or higher non-hematologic toxicity that was considered clinically significant, except the following cases, Grade 3 gastrointestinal symptoms that could be controlled with supportive therapy (example, appropriate use of antiemetics, antidiarrheals), and Grade 3 or higher electrolyte abnormalities that were not deemed clinically significant.

Number of Participants With Abnormal Clinically Significant Electrocardiogram (ECG) Findings

Time Frame: Baseline up to 30 days after last dose, or start of subsequent therapy, whichever occurred first (up to Cycle 38 Days 52 [Q2D] and 58 [QW] [Cycle=22 days (Q2D) and 28 days (QW)] in Escalation Phase; Cycle 49 Day 58 [Cycle=28 days] in Expansion Phase)

Number of Participants With TEAEs Categorized Into Investigations Related to Laboratory Test of Chemistry, Hematology or Urinalysis

Time Frame: Baseline up to 30 days after last dose, or start of subsequent therapy, whichever occurred first (up to Cycle 38 Days 52 [Q2D] and 58 [QW] [Cycle=22 days (Q2D) and 28 days (QW)] in Escalation Phase; Cycle 49 Day 58 [Cycle=28 days] in Expansion Phase)

Eastern Cooperative Oncology Group (ECOG) Performance Score

Time Frame: at EOSV (up to Cycle 38 Days 52 [Q2D] and 58 [QW] [Cycle length =22 days (Q2D) and 28 days (QW)] in Escalation Phase; Cycle 49 Day 58 [Cycle length =28 days] in Expansion Phase)

ECOG performance score was measured on 6 point scale to assess participant's performance status, where: 0 (fully active, able to carry on all pre-disease activities without restriction); 1 (restricted in physically strenuous activity, but ambulatory and able to carry out light or sedentary work); 2 (ambulatory greater than(\>) 50 percent (%) of waking hours), capable of all self-care, unable to carry out any work activities); 3 (capable of only limited self-care, confined to bed or chair \>50% of waking hours); 4(completely disabled, cannot carry on any self-care, totally confined to bed or chair); 5 (dead). A higher score indicated greater functional impairment.

Number of Participants With TEAEs Related to Physical Examination Findings

Time Frame: Baseline up to 30 days after last dose, or start of subsequent therapy, whichever occurred first (up to Cycle 38 Days 52 [Q2D] and 58 [QW] [Cycle=22 days (Q2D) and 28 days (QW)] in Escalation Phase; Cycle 49 Day 58 [Cycle=28 days] in Expansion Phase)

Clinically Significant Change From Baseline in Body Weight at End of Study Visit (EOSV)

Time Frame: Baseline up to EOSV (up to Cycle 38 Days 52 [Q2D] and 58 [QW] [Cycle length =22 days (Q2D) and 28 days (QW)] in Escalation Phase; Cycle 49 Day 58 [Cycle length =28 days] in Expansion Phase)

Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs) and Deaths

Time Frame: Baseline up to 30 days after last dose, or start of subsequent therapy, whichever occurred first (up to Cycle 38 Days 52 [Q2D] and 58 [QW] [Cycle=22 days (Q2D) and 28 days (QW)] in Escalation Phase; Cycle 49 Day 58 [Cycle=28 days] in Expansion Phase)
