Inclusion Criteria
  1. Histologically or cytologically confirmed diagnosis of extensive-stage small-cell lung cancer (ES-SCLC) with measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1; ES-SCLC is defined as: small-cell lung cancer (SCLC) that has spread beyond one hemithorax and regional lymph nodes on the same side (e.g., supraclavicular) to the contralateral hemithorax, lymph nodes, or more distant locations in the body
  2. Subjects with asymptomatic brain metastases or other central nervous system (CNS) disease at screening/diagnosis are eligible
  3. Males and females ≥ 18 years of age
  4. Eastern Cooperative Oncology Group (ECOG) performance status 0-1

Key

Exclusion Criteria
  1. Previous systemic therapy to treat small-cell lung cancer (SCLC). Subjects with recurrent or progressive limited-stage SCLC after previous systemic treatment are not eligible for study participation.
  2. Whole brain or focal radiation therapy within 14 days prior to Cycle 1 Day 1 (C1D1) for Phase 1b or prior to randomization for Phase 2
  3. Congestive heart failure (New York Heart Association [NYHA] class III to IV), symptomatic ischemia, conduction abnormalities uncontrolled by conventional intervention, or myocardial infarction within 6 months prior to prior to C1D1 for Phase 1b or prior to randomization for Phase 2

Carfilzomib CombinationCarfilzomibParticipants received carfilzomib on days 2, 3, 9, and 10 of each 21-day cycle as per the dose escalation schema, carboplatin at a target area under the curve (AUC) of 5 on day 1 of each cycle, and etoposide 100 mg/m² on days 1, 2, 3 of each 21-day cycle for up to 6 cycles. Participants with stable disease or better continued to receive carfilzomib alone until progressive disease (PD), unacceptable toxicity, withdrawal of consent, study closure, or death, whichever occurred earliest.
Carfilzomib CombinationCarboplatinParticipants received carfilzomib on days 2, 3, 9, and 10 of each 21-day cycle as per the dose escalation schema, carboplatin at a target area under the curve (AUC) of 5 on day 1 of each cycle, and etoposide 100 mg/m² on days 1, 2, 3 of each 21-day cycle for up to 6 cycles. Participants with stable disease or better continued to receive carfilzomib alone until progressive disease (PD), unacceptable toxicity, withdrawal of consent, study closure, or death, whichever occurred earliest.
Carfilzomib CombinationEtoposideParticipants received carfilzomib on days 2, 3, 9, and 10 of each 21-day cycle as per the dose escalation schema, carboplatin at a target area under the curve (AUC) of 5 on day 1 of each cycle, and etoposide 100 mg/m² on days 1, 2, 3 of each 21-day cycle for up to 6 cycles. Participants with stable disease or better continued to receive carfilzomib alone until progressive disease (PD), unacceptable toxicity, withdrawal of consent, study closure, or death, whichever occurred earliest.
Primary Outcome Measures
NameTimeMethod
Number of Participants With Dose-limiting ToxicitiesFirst 21-day Cycle

The maximum tolerated dose (MTD) was defined as the highest dose level at which \< 33% of participants experienced a dose-limiting toxicity (DLT) during the first 21-day cycle. Dose-limiting toxicities were evaluated according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 4.03. A DLT was defined as:

* A grade 3 or greater non-hematologic toxicity that was assessed as related to carfilzomib by the investigator except in the case of neuropathy. A grade 2 or higher neuropathy with pain was considered a DLT.

* Grade 4 neutropenia: absolute neutrophil count (ANC) \< 500 mm³, lasting ≥ 7 days despite granulocyte colony stimulating factor support, or any febrile (temperature \> 38.3°C) neutropenia (ANC \< 1000 mm³).

* Thrombocytopenia of any grade associated with clinically significant bleeding or platelet/blood transfusion

* Grade 4 fatigue lasting ≥ 7 days

* Grade 3 nausea, vomiting or diarrhea lasting ≥ 7 days.

Secondary Outcome Measures
NameTimeMethod
Maximum Plasma Concentration - Phase 2Cycle 1 Day 2

Pharmacokinetic (PK) analyses were specified as secondary endpoints for the phase 2 portion of the study; since phase 2 was not conducted, PK analyses were not performed.

Time of Maximum Plasma Concentration - Phase 2Cycle 1 Day 2

Pharmacokinetic (PK) analyses were specified as secondary endpoints for the phase 2 portion of the study; since phase 2 was not conducted, PK analyses were not performed.

Number of Participants With Adverse Events (AEs)From first day of any study treatment (i.e., carfilzomib, carboplatin, or etoposide) up to 30 days after the last day of study treatment. The median overall duration of treatment was 16 weeks.

The severity of each adverse event was assessed using the NCI-CTCAE Version 4.03 according to the following:

Grade 1 - Mild: Asymptomatic or mild symptoms; intervention not indicated

Grade 2 - Moderate: Minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental activities of daily living (ADL)

Grade 3 - Severe: Medically significant but not life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL

Grade 4 - Life-threatening

Grade 5 - Fatal.

A serious AE is an AE that met one or more of the following criteria:

* Death

* Life-threatening

* Required inpatient hospitalization or prolongation of an existing hospitalization

* Resulted in persistent or significant disability/incapacity

* A congenital anomaly/birth defect

* Important medical events that required medical or surgical intervention to prevent one of the outcomes above.

Area Under Plasma Concentration-Time Curve - Phase 2Cycle 1 Day 2

Pharmacokinetic (PK) analyses were specified as secondary endpoints for the phase 2 portion of the study; since phase 2 was not conducted, PK analyses were not performed.

Overall Survival (OS) - Phase 230 months

Overall Survival (OS) is defined as the time from randomization to the date of death. Overall survival was a specified secondary endpoint for the phase 2 portion of the study; since phase 2was not conducted, OS was not analyzed.
