  • Number of Participants With Peripheral Neuropathy [ Time Frame: From first dose of study drug to 30 days after the last dose; median duration of treatment was 14 weeks for participants with solid tumors and 44 weeks for participants with multiple myeloma. ]
    Participants with peripheral neuropathy or peripheral neuropathy-related adverse events, including hypoaesthesia, paraesthesia, dysaesthesia, and neuropathic pain.
  • Number of Participants With Adverse Events [ Time Frame: From first dose of study drug to 30 days after the last dose; median duration of treatment was 14 weeks for participants with solid tumors and 44 weeks for participants with multiple myeloma. ]

    Adverse events (AEs) were assigned a severity grade using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) grading scale version 3.0.

    Per protocol, adverse events were collected if they led to dose modification or dose discontinuation, were grade ≥ 3 or serious, or were events of peripheral neuropathy (any grade).

    A serious AE is one 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 in the offspring of an exposed subject
    • Important medical events that, based upon appropriate medical judgment, jeopardized the participant and may have required medical or surgical intervention to prevent one of the outcomes above.
evaluate the safety and efficacy of a long-term, twice weekly, every other week carfilzomib in subjects who have achieved and maintained a response to the completion of a previous carfilzomib treatment study

  • Overall Survival [ Time Frame: From first dose of study drug to 30 days after the last dose; median duration of treatment was 14 weeks for participants with solid tumors and 44 weeks for participants with multiple myeloma. ]
    Since participants were only followed up to 30 days after administration of last dose of study drug per protocol, Kaplan-Meier estimates of overall survival were not calculated. The number of participants who died within 30 days after administration of last dose of study drug is reported.
  • Progression-free Survival [ Time Frame: From first dose of study drug in study PX-171-010 to 30 days after the last dose; median duration of treatment was 14 weeks for participants with solid tumors and 44 weeks for participants with multiple myeloma. ]

    Progression-free survival (PFS) was defined as the time between the start of treatment and first evidence of documented disease progression or death (due to any cause), whichever occurred first.

    Disease progression was determined by the local investigator for regimens with the same baseline using the International Uniform Response Criteria (IMWG-URC) for participants with multiple myeloma and Response Evaluation Criteria in Solid Tumors (RECIST) criteria for solid tumor participants.

    PFS was re-calculated whenever the baseline was reset due to addition of new anti-cancer therapy or increase of carfilzomib dose/frequency.

  • Time to Progression [ Time Frame: From first dose of study drug in study PX-171-010 to 30 days after the last dose; median duration of treatment was 14 weeks for participants with solid tumors and 44 weeks for participants with multiple myeloma. ]
    Time to progression (TTP) was defined as the time between start of treatment to the first documentation of disease progression. TTP was re-calculated whenever the baseline was reset due to addition of new anti-cancer therapy or increase of carfilzomib dose/frequency.

A Study of Extended Carfilzomib Therapy for Patients Previously Enrolled in Carfilzomib Treatment Protocols
An Open-Label, Single-Arm, Phase 2 Study of Extended Carfilzomib Therapy in Subjects Previously Enrolled in Carfilzomib Treatment Protocols
This is a multi-center, open-label, Phase 2 study of carfilzomib to monitor the safety and efficacy of long-term or continuing carfilzomib therapy for patients who previously completed a primary carfilzomib treatment study.
Not Provided
Interventional
Phase 2
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
  • Multiple Myeloma
  • Solid Tumors
Drug: Carfilzomib
Carfilzomib dose levels ranged from 11 to 27 mg/m² for 2- to 10-minute infusions and 36 to 56 mg/m² for 30-minute infusions. Carfilzomib doses were administered on days 1, 2, 8, 9, 15, and 16 of a 28-day cycle. Dose level reduction to a minimum dose of 11 mg/m² for toxicity was permitted.
Other Names:
  • PR-171
  • PR171
  • Kyprolis®
Experimental: Carfilzomib
Participants received carfilzomib administered intravenously, using the same method, frequency, and dose level as in the last cycle of the participant's previous carfilzomib study. Treatment was continued until confirmation of disease progression, diagnosis of new malignancy, unacceptable toxicity, investigator discretion, voluntary withdrawal, or commercial availability of carfilzomib.
Intervention: Drug: Carfilzomib
