Brief Summary:
This is a single-centre, phase 1a (dose escalation) and 1b (dose expansion) study to evaluate the safety and tolerability of oral Selinexor in combination with nivolumab and ipilimumab in patients with advanced solid malignancies.

Condition or disease Intervention/treatment Phase
Advance Solid Malignancies Metastatic Solid Malignancies Drug: Selinexor in combination with nivolumab and ipilimumab Phase 1

Detailed Description:

Primary Objectives

  • To evaluate the safety and tolerability of selinexor in combination with nivolumab and ipilimumab
  • To determine the maximum tolerated dose (MTD), dose-limiting toxicities (DLTs), and recommended phase 2 dose (RP2D) of selinexor in combination with nivolumab and ipilimumab in patients with advanced or metastatic solid tumor malignancies.

Secondary Objectives

  • To determine Selinexor pharmacokinetics (PK) in Asian patients
  • To describe anti-tumor responses with the combination in patients with advanced or metastatic solid tumor malignancies.

Exploratory Objectives

  • To assess the immunomodulatory effects of selinexor in solid tumour malignancies and circulating immune cells
  • To identify biomarkers of response to the combination of selinexor and nivolumab + ipilimumab. We will explore changes in PDL1 expression, T cell infiltration (including CD4 and CD8 positive cells), gene expression profiles on serial tumor biopsies pre-selinexor, post-selinexor alone, and after the combination of selinexor and ipilimumab + nivolumab where feasible.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 30 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: For all patients, the phase I drug combination will be preceded by a 14-day run in period where selinexor alone will be administered and biopsies will be obtained both pre-and post selinexor dosing. Patients will be treated with all three drugs until disease progression (as defined by RECIST criteria) or intolerable drug toxicity.
Masking: None (Open Label)
Primary Purpose: Treatment

Arm Intervention/treatment
Experimental: patients with advanced solid malignancies
Patients will be dosed with selinexor once a week continuously in a 6 week cycle. Nivolumab will be administered on biweekly of each cycle . Ipilimumab will be dosed only on D1 of each cycle . Ipilimumab will continue for a maximum of 4 cycles. Nivolumab and selinexor will continue for up to 24 months or until discontinuation criteria is met.
Drug: Selinexor in combination with nivolumab and ipilimumab
Patients will commence at dose level 1. One cycle is 42 days (6 weeks) for all three agents. At dose level 1, selinexor will be dosedorally weekly, and nivolumab at 2 weekly + ipilimumab 1mg/kg 6 weekly. Patients can have dosing interruptions or reductions of any drug independently of one another, depending on the drug causing the toxicity




Primary Outcome Measures :
  1. Objective disease response assessment [ Time Frame: 3 years ]
    to be made according to standard, international RECIST 1.1 criteria for solid tumors.

  2. progression free survival (PFS) [ Time Frame: 3 years ]
    the time interval from the starting date of combination treatment to the date of disease progression on treatment

  3. duration of response (DOR) [ Time Frame: 3 years ]
    is defined as the time from documentation of tumor response to disease progression

  4. Duration of stable disease [ Time Frame: 3 years ]
    is defined as the time from first RECIST assessment scan documenting stable disease by RECIST criteria, to disease progression

Ages Eligible for Study:   21 Years to 99 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Age ≥ 21
  2. Willing and able to provide written informed consent in accordance with local institutional guidelines.
  3. Dose Escalation Phase: Patients with histologically or cytologically confirmed advanced or metastatic solid tumors who have radiological evidence of progressive disease on study entry that is deemed unlikely to benefit from further standard therapy.
  4. Dose Expansion phase: Patients with previously treated, metastatic or advanced recurrence malignancy confirmed histologically or cytologically. Patients must have evidence of progressive disease on study entry that is deemed unlikely to benefit from further standard therapy.
  5. There is no upper limit on the number of prior treatments. Hormone ablation therapy is considered an anticancer regimen. Radiation and surgery are not considered anticancer regimens.
  6. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0-1.
  7. Adequate hepatic function within 14 days prior to C1D1:

    1. Total bilirubin < 1.5 × upper limit of normal (ULN) (except patients with Gilbert's syndrome who must have a total bilirubin of < 3 × ULN), and
    2. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) normal to <3 × ULN.
  8. Adequate renal function within 14 days prior to C1D1 as determined by serum creatinine of ≤1.5 mg/dL OR estimated creatinine clearance of ≥ 30 mL/min, calculated using the Cockcroft and Gault formula (140 - Age) • Mass (kg)/ (72 • creatinine mg/dL); multiply by 0.85 if female.
