Brief summary:
Open-label, multi-center, single-arm, Phase 2 study of oral selinexor in patients with SCC of the head and neck (HN-SCC; Cohort 1), lung (L-SCC; Cohort 2), or esophagus (E-SCC; Cohort 3) who have relapsed or have metastasis following chemotherapy.

Detailed description:
This is a multicenter, open-label, single-arm Phase 2 study of the SINE selinexor given orally to patients diagnosed with advanced SCC of the head and neck, lung, or esophagus who have experienced relapse and/or metastasis following multiple prior chemotherapy treatments (\<2 lines of therapy).

Patients will receive fixed doses of selinexor tablets twice weekly in 28-day cycles. Patients may continue from one cycle to the next without interruption as along as all criteria are met and no reason for discontinuation occurs.

Arms:
arm 1: Participants with advanced squamous cell carcinoma (SCC) of head and neck, who had relapsed or had metastasis following chemotherapy, received a fixed dose of 60 milligram (mg) selinexor oral tablets twice weekly on Days 1 and 3 of a 28-day cycle (8 doses in 4 weeks) until disease progression or development of unacceptable toxicities. After completion of Cycle 2, for participants with absence of any grade 2 toxicity and thrombocytopenia (platelets less than \[\<\] 100\*10\^9 per litre \[/L\]), dose may be increased to 80 mg selinexor oral tablets twice weekly as assessed by investigator in a 28-day cycle until disease progression or development of unacceptable toxicities. arm 2: Participants with advanced SCC of lungs, who had relapsed or had metastasis following chemotherapy, received a fixed dose of 60 mg selinexor oral tablets twice weekly on Days 1 and 3 of a 28-day cycle (8 doses in 4 weeks) until disease progression or development of unacceptable toxicities. After completion of Cycle 2, for participants with absence of any grade 2 toxicity and thrombocytopenia (platelets \<100\*10\^9/L), dose may be increased to 80 mg selinexor oral tablets twice weekly as assessed by investigator in a 28-day cycle until disease progression or development of unacceptable toxicities. arm 3: Participants with advanced SCC of esophagus, who had relapsed or had metastasis following chemotherapy, received a fixed dose of 60 mg selinexor oral tablets twice weekly on Days 1 and 3 of a 28-day cycle (8 doses in 4 weeks) until disease progression or development of unacceptable toxicities. After completion of Cycle 2, for participants with absence of any grade 2 toxicity and thrombocytopenia (platelets \<100\*10\^9/L), dose may be increased to 80 mg selinexor oral tablets twice weekly as assessed by investigator in a 28-day cycle until disease progression or development of unacceptable toxicities.
