- Brief Summary
This phase I/II trial tests the safety, side effects and best dose of selinexor given in combination with the usual chemotherapy (temozolomide) and compares the effect of this combination therapy vs. the usual chemotherapy alone (temozolomide) in treating patients with glioblastoma that has come back (recurrent). Selinexor is in a class of medications called selective inhibitors of nuclear export (SINE). It works by blocking a protein called CRM1, which may keep cancer cells from growing and may kill them. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells and slow down or stop tumor growth. Giving selinexor in combination with usual chemotherapy (temozolomide) may shrink or stabilize the tumor better than the usual chemotherapy with temozolomide alone in patients with recurrent glioblastoma.
- Detailed Description
PRIMARY OBJECTIVES:
I. To determine the maximum tolerated dose of temozolomide followed by selinexor in recurrent glioblastoma patients as determined by dose-limiting toxicities (DLTs) and the total toxicity profile. (Phase I) II. To evaluate the efficacy of sequentially administering temozolomide and selinexor in recurrent glioblastoma as determined by progression-free survival (PFS). (Phase 2)
SECONDARY OBJECTIVES:
I. To evaluate overall response rate as determined by Response Assessment in Neuro-Oncology (RANO) response criteria.
II. To evaluate the efficacy of sequentially administering temozolomide and selinexor in recurrent glioblastoma as determined by 6-month PFS (6mPFS) and overall survival (OS).
III. To validate signatures of vulnerability to predict response to selinexor through ribonucleic acid (RNA) sequencing for 6 top-scoring gene pairs, whole exome sequencing, P53, EGFR, and Mcl-1.
OUTLINE: This is a phase I, dose-escalation study of selinexor in combination with fixed dose temozolomide followed by a phase II study that compares selinexor temozolomide combination therapy vs. temozolomide monotherapy. Patients are randomized to 1 of 2 groups for the phase II part of this trial.
GROUP I (Phase II): Patients receive temozolomide orally (PO) on days 1-5 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
GROUP II (Phase I and II): Patients receive temozolomide PO on days 1-5 of each cycle and selinexor PO on days 8 and 15 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. (Phase I completed as of April 2024)
Patients undergo magnetic resonance imaging (MRI) throughout the study and blood sample collection while on study.
After completion of study treatment, patients are followed up every 2 months up to 2 years.
Recruitment & Eligibility
- Status
- RECRUITING
- Sex
- All
- Target Recruitment
- 97
- Patients must have histologically confirmed glioblastoma (IDH wild-type, MGMT promoter methylated) that has undergone resection or biopsy upon first recurrence. Recurrence at site of prior involvement is defined by histopathological evidence of viable neoplastic cells associated with any of the following: mitotic activity, increased proliferation rate, micro-endothelial proliferation, or pseudo-palisading necrosis
- Prior to resection or biopsy, patients must have measurable disease, defined as at least one bi-dimensional contrast-enhancing lesion with clearly defined margins, with 2 perpendicular diameters of at least 10 mm, visible on >= 2 axial slices
- Patients must have received first-line treatment of temozolomide plus radiotherapy
- Patients must not have received any prior therapy aside from resection or biopsy for their recurrent disease
- Age >= 18 years. Because no dosing or adverse event data are currently available on the use of selinexor (KPT-330) in combination with temozolomide in patients < 18 years of age, children are excluded from this study
- Karnofsky performance status >= 60% (Eastern Cooperative Oncology Group [ECOG] =< 2)
- Absolute neutrophil count >= 1,500/mcL
- Platelets >= 100,000/mcL
- Hemoglobin >= 10 g/dL
- Total bilirubin =< 2 x institutional upper limit of normal (ULN)
- Aspartate aminotransferase (AST) serum glutamic oxaloacetic transaminase (SGOT)/ alanine transaminase (ALT) serum glutamic-pyruvic transaminase (SGPT) =< 3 x institutional ULN
- Glomerular filtration rate (GFR) >= 30 mL/min/1.73 m^2
- Human immunodeficiency virus (HIV)-infected patients on effective anti-retro-viral therapy with undetectable viral load within 6 months are eligible for this trial
- For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
- Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load
- Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
- Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better
- The effects of selinexor (KPT-330) and temozolomide on the developing human fetus are unknown. For this reason and because selective nuclear export inhibitors as well as deoxyribonucleic acid (DNA) alkylating agents are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation, and for 180 days after the last dose of temozolomide. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 90 days after completion of study treatment administration
- Ability to understand and the willingness to sign a written informed consent document. Participants with impaired decision-making capacity who have a legally-authorized representative (LAR) and/or family member available will also be eligible
- Patients who have had chemotherapy must have full recovery of organ and marrow function following the nadir of the last chemotherapy cycle
- Patients who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities > grade 1) with the exception of alopecia
- Patients who are receiving any other investigational agents
- Patients who have previously received bevacizumab
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to selinexor (KPT-330) or temozolomide
- History of hypersensitivity to dacarbazine (DTIC), since both dacarbazine and temozolomide are metabolized to 5-(3-methyltriazen-1-yl)-imidazole-4-carboxamide (MTIC)
- Patients with uncontrolled intercurrent illness
- Pregnant women are excluded from this study because selinexor (KPT-330) is a selective inhibitor of nuclear export with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with selinexor (KPT-330), breastfeeding is not allowed for mothers during treatment with selinexor (KPT-330) and for 7 days after the last dose. These potential risks may also apply to other agents used in this study
- Hospitalized patients with severe coronavirus disease of 2019 (COVID-19) who are >= 75 years old, or with a high-risk COVID-GRAM score, or with lactate dehydrogenase (LDH) > 370 (U/L) AND D-Dimer > 600 mcg/L FEU should not receive low-dose selinexor (KPT-330) pending additional results

- Primary Outcome Measures
Name Time Method Progression-free survival (PFS) (Phase II) From randomization to date of disease progression (either progression of existing lesions or appearance of new lesions), death, or date of last contact, whichever occurs first, assessed up to 3 years Patients who experience disease progression or death will be considered to have experienced a PFS-event; otherwise the patient is considered censored at last contact.
Recommended phase 2 dose (RP2D) (Phase I) Up to 28 days Any eligible patient who receives at least one dose of protocol-defined therapy will be considered evaluable for dose-limiting toxicity (DLT) if either of the following occurs: (1) the patient experiences a DLT during cycle 1 of therapy; or (2) the patient receives at least 4 doses of temozolomide and 1 dose of selinexor. All other patients enrolled during the phase 1 portion of the study will be considered inevaluable for DLT and may be replaced for the purposes of establishing the RP2D.
- Secondary Outcome Measures
Name Time Method Six-month progression-free survival (PFS-6) At 6 months Any patient considered evaluable for RANO response will be considered evaluable for PFS-6. Any evaluable patient who is considered progression free for the primary analysis will be considered a PFS-6 responder. All other evaluable patients will be considered PFS-6 non-responders.
Median overall survival Time between the date of randomization and the date of death or date of last contact, whichever occurs first, assessed up to 3 years Will be calculated from the Kaplan-Meier estimate of the probability of death as a function of time since enrollment. Ninety-five percent (95%) confidence intervals will be calculated as well.
Response according to response assessment in neuro-oncology criteria (RANO) criteria Up to 3 years A patient who is evaluated as complete response (CR), partial response (PR), or stable disease (SD) will be considered a RANO-responder. All other patients will be considered RANO-non-responders. Response rate will be calculated and comparisons made using categorical data methods.
Molecular signatures of vulnerability Up to 3 years Will be assessed using logistic regression for the outcome measure (RANO response) and using proportional hazard regression with the biological characteristic of interest as the predictor variable for risk for PFS event. Patients considered evaluable for RANO response and PFS, respectively, will contribute to the analyses for these exploratory outcomes. Two-sided statistical testing will be employed, and a p-value of 0.05 or less will be considered as indicating significant evidence of association between the particular signature and the outcome of interest.
