- Detailed Description
This is a single-arm, multi-center, open-label phase 2 study of the SINE™ compound selinexor given orally to patients with relapsed or refractory PTCL or CTCL.
Approximately 60 patients with relapsed or refractory PTCL or CTCL who meet the eligibility criteria and have none of the exclusion criteria will be enrolled to receive selinexor until either disease progression or intolerance has occurred.
Enrolled patients will be given selinexor as an oral fixed 60 mg dose (equivalent to \~35 mg/m²) on Days 1 and 3 of Weeks 1-4 of each 4-week cycle (total 8 doses per cycle).
There is no maximum treatment duration. Patients will receive supportive therapy to mitigate selinexor side effects, as well as best supportive care (BSC).
Patients enrolled under Protocol Versions \<3.0 were to receive selinexor orally, at a fixed dose of 60 mg (equivalent to \~35 mg/m²) on Days 1 and 3 of Weeks 1-3 of each 4-week cycle (total of 6 doses per cycle). Selinexor was not taken during Week 4.
For all patients enrolled in this study (regardless of the protocol version) who continued onto Cycle 3 and forward, the dose was to be increased by 20 mg to 80 mg (administered on Days 1 and 3 of Weeks 1-4), only after consultation with the Sponsor's Medical Monitor.

- Primary Outcome Measures
Name Time Method Best Overall Response: Progressive Disease (PD) Disease response was assessed at screening and every 8 weeks (patients with PTCL); or at Cycle 1 Day 1 and every 4 weeks (patients with CTCL), until disease progression. Patients whose best overall response to study treatment was PD. Progression was defined as the first occurrence of progressive disease (PD). Objective disease response assessment in PTCL patients was made according to the revised response criteria based on the International Working Group (IWG) guidelines for malignant lymphoma (Cheson, 2007). Objective disease response assessment in CTCL patients was assessed according to the revised CTCL Consensus Response Criteria (Olsen, 2011) using physical examination, including the Modified Severity Weighted Assessment Tool (mSWAT) for skin assessment. CTCL Global Response Score was used as a secondary efficacy assessment. Clinical disease progression in the absence of formal criteria for PD must be documented by a physician.
Best Overall Response: Not Evaluable (NE) Disease response was assessed at screening and every 8 weeks (patients with PTCL); or at Cycle 1 Day 1 and every 4 weeks (patients with CTCL), until disease progression. Patients who could not be assessed quantitatively for disease response for any reason.
Overall Response Rate (ORR) Disease response was assessed at screening and every 8 weeks (patients with PTCL); or at Cycle 1 Day 1 and every 4 weeks (patients with CTCL), until disease progression. Overall Response (OR) = Complete Response (CR) + Partial Response (PR). Objective disease response assessment in PTCL patients was made according to the revised response criteria based on the International Working Group (IWG) guidelines for malignant lymphoma (Cheson, 2007). Objective disease response assessment in CTCL patients was assessed according to the revised CTCL Consensus Response Criteria (Olsen, 2011) using physical examination, including the Modified Severity Weighted Assessment Tool (mSWAT) for skin assessment. CTCL Global Response Score was used as a secondary efficacy assessment. Progression was defined as the first occurrence of progressive disease (PD) per the revised response criteria. Clinical disease progression in the absence of formal criteria for PD must be documented by a physician.
Best Overall Response: Complete Response (CR) Disease response was assessed at screening and every 8 weeks (patients with PTCL); or at Cycle 1 Day 1 and every 4 weeks (patients with CTCL), until disease progression. Patients who achieved CR (disappearance of all detectable evidence of disease). Objective disease response assessment in PTCL patients was made according to the revised response criteria based on the International Working Group (IWG) guidelines for malignant lymphoma (Cheson, 2007). Objective disease response assessment in CTCL patients was assessed according to the revised CTCL Consensus Response Criteria (Olsen, 2011) using physical examination, including the Modified Severity Weighted Assessment Tool (mSWAT) for skin assessment. CTCL Global Response Score was used as a secondary efficacy assessment.
Best Overall Response: Partial Response (PR) Disease response was assessed at screening and every 8 weeks (patients with PTCL); or at Cycle 1 Day 1 and every 4 weeks (patients with CTCL), until disease progression. Patients whose best overall response to study treatment was PR (regression of measurable disease and no new sites). Objective disease response assessment in PTCL patients was made according to the revised response criteria based on the International Working Group (IWG) guidelines for malignant lymphoma (Cheson, 2007). Objective disease response assessment in CTCL patients was assessed according to the revised CTCL Consensus Response Criteria (Olsen, 2011) using physical examination, including the Modified Severity Weighted Assessment Tool (mSWAT) for skin assessment. CTCL Global Response Score was used as a secondary efficacy assessment.
Best Overall Response: Stable Disease (SD) Disease response was assessed at screening and every 8 weeks (patients with PTCL); or at Cycle 1 Day 1 and every 4 weeks (patients with CTCL), until disease progression. Patients whose best overall response to study treatment was SD (failure to attain criteria needed for CR or PR, or to meet criteria for PD). Objective disease response assessment in PTCL patients was made according to the revised response criteria based on the International Working Group (IWG) guidelines for malignant lymphoma (Cheson, 2007). Objective disease response assessment in CTCL patients was assessed according to the revised CTCL Consensus Response Criteria (Olsen, 2011) using physical examination, including the Modified Severity Weighted Assessment Tool (mSWAT) for skin assessment. CTCL Global Response Score was used as a secondary efficacy assessment.
- Secondary Outcome Measures
Name Time Method Progression Free Survival (PFS) Study treatment start date to date of disease progression or date of death. Patients without documented PD are censored on date of last radiologic assessment. Duration of time from start of study treatment to date of disease progression or death from any cause.
Duration of Stable Disease, Including Patients With Partial Response Date of start of study treatment to date of progression. Patients without documented PD are censored on date of last radiologic assessment. Duration of time from the date of start of study treatment to the date of disease progression. Objective disease response assessment in PTCL patients was made according to the revised response criteria based on the International Working Group (IWG) guidelines for malignant lymphoma (Cheson, 2007). Objective disease response assessment in CTCL patients was assessed according to the revised CTCL Consensus Response Criteria (Olsen, 2011) using physical examination, including the Modified Severity Weighted Assessment Tool (mSWAT) for skin assessment. CTCL Global Response Score was used as a secondary efficacy assessment.
Disease Control Rate (DCR) Disease response was assessed at screening and every 8 weeks (patients with PTCL); or at Cycle 1 Day 1 and every 4 weeks (patients with CTCL), until disease progression. Percentage of patients who have CR, PR, or SD lasting ≥ 8 weeks. Objective disease response assessment in PTCL patients was made according to the revised response criteria based on the International Working Group (IWG) guidelines for malignant lymphoma (Cheson, 2007). Objective disease response assessment in CTCL patients was assessed according to the revised CTCL Consensus Response Criteria (Olsen, 2011) using physical examination, including the Modified Severity Weighted Assessment Tool (mSWAT) for skin assessment. CTCL Global Response Score was used as a secondary efficacy assessment.
