Criteria

Inclusion Criteria:

1. Dose Escalation Phase: Patients with advanced or metastatic solid tumors for which no standard therapy is available. For Schedule 6 only: patients with colorectal cancer with liver metastasis.

Dose Expansion Phase: Previously treated, metastatic or advanced recurrent malignancy with 1 of the following diagnoses, which has been confirmed histologically or cytologically:

• Up to 12 patients with metastatic colorectal cancer with a history of progression or recurrence following prior fluoropyrimidine, irinotecan and platinum containing regimens as well as bevacizumab. In addition, patients with Kras wild type tumor must have received at least one EGFR blocker.

• Up to 6 patients with histological or cytological documentation of advanced ovarian, fallopian tube, or primary peritoneal carcinoma with a history of progression or recurrence following at least one prior platinum and one taxane based chemotherapy

• Up to 12 patients with incurable Squamous cell cancers as follows:

1. A minimum of 4 Squamous Non-Small Cell Lung Cancer (Sq-NSCLC)

2. A minimum of 4 Squamous Cell Carcinomas of the Head and Neck (Sq-HNC)

3. Squamous Cell Carcinoma of the Cervix (SqCC) All patient with Squamous Cell Carcinomas should have a documented history of progression or recurrence following at least one prior platinum based chemotherapy or chemotherapy/radiation containing regimen

• Up to 6 patients with castration-resistant prostate cancer (CRPC) that was pathologically confirmed as adenocarcinoma of the prostate and with evidence of metastatic disease on bone scan or other imaging. Patient must have progressive disease after at least one hormonal treatment and one cytotoxic therapy e.g. with docetaxel, mitoxantrone.

• Up to 12 patients with unresectable metastatic melanoma whose disease progressed on at least 1 prior systemic anticancer regimen (chemotherapy, biological or immunotherapy, or targeted therapy). Enrollment to this cohort may have been stopped before reaching 12 patients once the dose-escalation portion of the study was completed.

• Approximately 6 patients with advanced or metastatic solid tumors were to be enrolled on Schedule 8 at a starting dose of 35 mg/m^2 to assess general tolerability and activity of selinexor.

2. Dose Escalation Phase: Patients have exhausted, or be deemed to not benefit from, further conventional therapy and have evidence of progressive disease on study entry.

Both Dose Escalation and Expansion Phases: There is no upper limit on the number of prior treatments provided that all inclusion criteria are met and exclusion criteria are not met. Hormone ablation therapy is considered an anticancer regimen. Radiation and surgery are not considered anticancer regimes.

Exclusion Criteria:

1. Radiation, chemotherapy, or immunotherapy or any other anticancer therapy ≤3 weeks prior to cycle 1 day 1 and mitomycin C and radioimmunotherapy 6 weeks prior to cycle 1 day 1;

2. Except for patients with GBM/ AnaA in the Expansion Phase, patients with active CNS malignancy are excluded. Asymptomatic small lesions are not considered active. Treated lesions may be considered inactive if they are stable for at least 3 months.
