Summary
This early phase I trial tests brain concentration level and safety of defactinib or VS-6766 for the treatment of patients with glioblastoma. Recently, two new drugs that seem to work together have been shown to have promising treatment effects in tissue culture and animal models of glioblastoma. Each inhibits a different glioblastoma growth pathway and when used together may create a larger effect on tumor growth than either alone. Growth pathway describes a series of chemical reactions in which a group of molecules in a cell work together to control cell growth. It is known that glioblastoma tumor cells can grow because of lack of regulation. Both Pyk2 and the closely related kinase (FAK) proteins help regulate tumor cell invasion, unless they are produced in large amounts (over expressed). Specifically, Raf and FAK/Pyk2 regulation of cell division is activated quite a bit more in gliomas compared to normal tissues. Recently developed inhibitors of Raf (VS-6766) and FAK (defactinib) which belong to a class of medications called kinase inhibitors, are aimed to bring their activity to proper levels and may stop tumor growth.Phase:

Criteria
Inclusion Criteria:- New or recurrent glioblastoma diagnosed by neuroimaging techniques for which surgical
resection is indicated
- Age older than 21 years
- An Eastern Cooperative Group (ECOG) performance status =< 1
- Hemoglobin (Hb) >= 9.0 g/dL. If a red blood cell transfusion has been administered the
Hb must remain stable and >= 9.0 g/dL for at least 1 week prior to first dose of study
therapy.
- Platelets >= 100,000/mm^3
- Absolute neutrophil count (ANC) >= 1500/mm^3
- Total bilirubin =< 1.5 × upper limit of normal (ULN) per the institution; patients
with Gilbert syndrome may enroll if total bilirubin < 3.0 mg/dL (51 umole/L)
- Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 2.5 × ULN (or <
5x ULN in patients with liver metastases)
- Creatinine clearance rate of >= 50 mL/min as calculated by the Cockcroft-Gault formula
or serum creatinine of =< 1.5 x ULN
- Albumin >= 3.0 g/dL (451 umole/L)
- Creatine phosphokinase (CPK) =< 2.5 x ULN
- Left ventricular ejection fraction >= 50% by echocardiography (ECHO) or multiple-gated
acquisition (MUGA) scan
- Baseline QTc interval < 460 ms for women and =< 450 ms for men (average of triplicate
readings) (Common Terminology Criteria for Adverse Events [CTCAE] Grade 1) using
Fredericia's QT correction formula. NOTE: This criterion does not apply to subjects
with a right or left bundle branch block
- Adequate recovery from toxicities related to prior treatments to at least Grade 1 by
CTCAE v 5.0. Exceptions include alopecia and peripheral neuropathy grade =< 2
- Male and female patients with reproductive potential agree to use highly effective
method of contraceptive (per Clinical Trial Facilitation Group [CFTG] recommendations)
during the trial and for 3 months following the last dose of VS-6766 for male
patients, and 1 month following the last dose of VS-6766 for female patients.
Exclusion Criteria:
- Clinically significant gastrointestinal abnormalities, requirement for systemic
anticoagulation or potent CYP 2C8 inhibitors, and history of clinically significant
cardiac or pulmonary disorders
- Minors will be excluded from the investigation. Glioblastoma is the major form of
brain cancer in people over 50 years old. Pediatric cases of glioblastoma are
relatively rare. Besides this, there are crucial molecular differences between adult
and pediatric gliomas. Our preliminary data for proposed investigation were obtained
on GBM specimens and cultures developed from GBM tissues donated by adult subjects.
Results of investigation of adult glioma tissue cannot simply be extrapolated to
children. Therefore, our primary research focus is the investigation of GBM in adults.
If appropriate, a separate, age-specific study in children will be performed
- Pregnant women will be excluded from the study as altered hormonal and immunological
status can affect the study results
- Prisoners will be excluded from the study
- Systemic anti-cancer therapy within 4 weeks of the first dose of study therapy
- History of prior malignancy, with the exception of curatively treated malignancies or
malignancies with very low potential for recurrence or progression
- Major surgery within 4 weeks (excluding placement of vascular access), minor surgery
within 2 weeks, or palliative radiotherapy within 1 week of the first dose of VS-6766
- Exposure to medications (with or without prescription), supplements, herbal remedies,
or foods with potential for drug-drug interactions with VS-6766 within 14 days prior
to the first dose of VS-6766 and during the course of therapy, including:
- VS-6766: strong CYP3A4, inhibitors or inducers, due to potential drug-drug
interactions with VS-6766 and/or defactinib
- Defactinib: strong CYP3A4, CYP2C9, and P-glycoprotein (P-gp) inhibitors or
inducers, due to potential drug-drug interactions with VS-6766 and/or defactinib
- Known hepatitis B, hepatitis C or human immunodeficiency virus (HIV) infection that is
active and/or requires therapy
- Active skin disorder that has required systemic therapy within the past 1 year
- History of rhabdomyolysis
- Concurrent ocular disorders:
- Patients with history of glaucoma, history of retinal vein occlusion (RVO),
predisposing factors for RVO, including uncontrolled hypertension, uncontrolled
diabetes
- Patients with history of retinal pathology or evidence of visible retinal
pathology that is considered a risk factor for RVO, intraocular pressure > 21 mm
Hg as measured by tonometry, or other significant ocular pathology, such as
anatomical abnormalities that increase the risk for RVO
- Patients with a history of corneal erosion (instability of corneal epithelium),
corneal degeneration, active or recurrent keratitis, and other forms of serious
ocular surface inflammatory conditions
- Concurrent congestive heart failure, prior history of class III/ IV cardiac disease
(New York Heart Association [NYHA]), myocardial infarction within the last 6 months,
unstable arrhythmias, unstable angina, or severe obstructive pulmonary disease
- Patients with the inability to swallow oral medications or impaired gastrointestinal
absorption due to gastrectomy or active inflammatory bowel disease
- Patients with a history of hypersensitivity to any of the inactive ingredients
(hydroxypropylmethylcellulose, mannitol, magnesium stearate) of the investigational
product
