Study Details

Study Description

Brief Summary

This will be a single-arm open-label prospective pilot feasibility trial recruiting 10 adult patients with recurrent glioblastoma who are assigned to receive the personalized study treatment based on the genetic profile of their recurrent GBM tumor resected at the time of surgery. It will be aimed to gather preliminary information on the study intervention and the feasibility of conducting a full-scale trial.

Outcome Measures

Primary Outcome Measures

Success rate of personalized GBM treatment based on molecular characterization of recurrent tumor [From date of initial consent to participate to the end of follow up period (24 months)]
Percentage of patients, interested in participating, consented and detected with target mutations and completed the treatment with one of the 5 study drugs

Secondary Outcome Measures

Overall survival (OS) [From date of study drug administration until date of death from any cause (approximately 24 months)]
OS is calculated as the period from the day of starting administration of the study drug to the day of death from any cause.
Progression free survival (PFS) [From date of study drug administration until date of radiographic confirmed progression (approximately 2 years)]
PFS is calculated as the period from the day of starting administration of the study drug to the date that disease progression is confirmed by radiographic assessment and RANO criteria.
Quality of Life (QoL) EORTC QLQ-C30 [Baseline until the end of treatment]
The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. Participant responses to the questions "How would you rate your overall health during the past week?" and "How would you rate your overall quality of life during the past week?" are scored on a 7-point scale (1= Very poor to 7=Excellent). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. A higher score indicates a better overall health status. The change from baseline in EORTC QLQ-C30 Items 29 and 30 combined score will be presented.
Quality of Life (QoL) EORTC QLQ BN-20 [Baseline until the end of treatment]
Quality of Life measures are recorded according to EORTC QLQ BN-20 module, which is validated for brain tumor patients and measured as a unit of scale. This is a standard tool for assessing patient reported quality of Life along time during treatment. EORTC QLQ BN-20 (BN-20): 4 scales comprised of multiple items and 7 single items. All items are rated on a 4-point Likert-type scale, 1=not at all' to 4=very much, and linearly transformed to a 0-100 scale, higher scores indicating more severe symptoms. The scores across all time points were averaged to obtain the mean.

Other Outcome Measures

Genomic and expression profiling [From date of initial consent to participate to end of follow up period (24 months)]
Number of patients for whom we were able to have genomic and expression profiling on their tissue samples and organoids
Organoid drug response [From date of initial consent to participate to end of follow up period (24 months)]
Number of patients for whom we can determine organoid drug response to study drugs
Correlation of genomic and expression profiling of tissue and organoid with the organoid's best drug response [From date of initial consent to participate to end of follow up period (24 months)]
Number of patients for whom the genomic and expression profiling of their tissue and organoid directly correlates to the organoid's best drug response

Eligibility Criteria

Criteria

Ages Eligible for Study:

18 Years and Older

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

Inclusion Criteria:

Study participant has provided informed consent prior to initiation of any study specific activities/procedures.
Adult participants, male and female, aged ≥18 who have a pathologically confirmed IDH-wild type glioblastoma, with first or second progression of the tumor, after initial treatment with radiation therapy and temozolomide.
Recurrence is amenable to resection.
Performance status: ECOG ≤2.
Women of child bearing potential (WOCBP) must have a negative serum (or urine) pregnancy test at the time of screening. WOCBP is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy or bilateral salpingectomy) and is not postmenopausal. Menopause is defined as 12 months of amenorrhea in a woman over age 45 years in the absence of other biological or physiological causes.
Patients of childbearing potential must adhere to the contraception requirement from screening throughout the study period up to 180 days after the last dose of study intervention. Women/men of childbearing potential must have agreed to use two highly effective contraceptive methods. In addition to routine contraceptive methods such as condom use, oral contraceptive, intrauterine device (IUD), intrauterine hormone-releasing system (IUS), "effective contraception" also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal ligation, or vasectomy/vasectomized partner. However, if at any point a previously celibate patient chooses to become heterosexually active during the time period for use of contraceptive measures outlined in the protocol, he/she is responsible for beginning contraceptive measures.

Note: abstinence is acceptable if this is established and preferred contraception for the patient and is accepted as a local standard.

Able to undergo brain MRIs.
Females must not be breastfeeding, throughout the study period up to 180 days after the last dose of study intervention.
Male patients should agree to not donate sperm during the study for at least 6 months until discontinuation of study drug.

Exclusion Criteria:

Patients with history of abnormal left ventricular ejection fraction (LVEF≤ 45%).

Bilirubin >1.5 x ULN,
eGFR <60

Patients with a history of ILD (interstitial lung disease) must be excluded.
Patients with severe hepatic impairment (Child Pugh C).
A significantly abnormal ECG (baseline QTcF interval > 450 msec).

Active hepatitis B or C infection and/or known history of HIV infection.

Subject will not be available for protocol-required study visits or procedures, to the best of the subject's and investigator's knowledge.
Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks from the date of signing the informed consent form.
Patients who are hypersensitive to any ingredients in the formulation of the study drugs or their excipients.
Patients receiving active treatment for a different cancer.
If recent bacterial infection, patients need to have completed antibiotic course prior to commencing study drug.
