What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This pilot study tested a device called NaviFUS that uses focused ultrasound to temporarily open the blood-brain barrier, combined with the drug bevacizumab (Avastin), in 6 patients with recurrent glioblastoma (a type of brain cancer). The goal was to see if the combination is safe and can slow tumor growth. Patients received the treatment after standard therapies had failed.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Bevacizumab (Avastin) combined with focused ultrasound (NaviFUS system)
What this could lead to
If successful, this approach could offer a new way to deliver drugs to brain tumors by temporarily opening the blood-brain barrier, potentially improving treatment for recurrent glioblastoma.
What could go wrong
This is a very early pilot study with only 6 participants, so results may not apply to a larger population. The treatment may not improve survival or could cause side effects from the ultrasound or drug.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Adult male/female patients ≥ 20 years of age 2. Patients with histologically confirmed glioblastoma, recurrent after prior radiotherapy and temozolomide chemotherapy. 3. Patient may have been operated for recurrence. If operated: with measurable residual tumor 4. Minimum interval since completion of radiation treatment is 12 weeks 5. Patients if already on the steroids then should be on a stable dose of steroids for at least 7 days prior to study treatment 6. Body mass index (BMI) ≥17 kg / m2 7. Minimum interval since last drug therapy: * 1 week for non-cytotoxic agents (e.g., interferon, tamoxifen), daily chemotherapy (e.g., metronomic temozolomide, cytoxan) or targeted therapies administered daily (e.g., gleevec, tarceva) * 4 weeks since last cytotoxic therapy * 6 weeks since the completion of a nitrosourea-containing chemotherapy regimen (e.g., carmustine (BCNU)) 8. Patients with life expectancy ≥ 3 months 9. The Karnofsky performance status (KPS) in the patient must be \> 60 10. Eastern Cooperative Oncology Group (ECOG) Score ≤ 2 11. Adequate hepatic, renal, coagulation, and hematopoietic function * Hemoglobin ≥ 8 g/dL * Platelets ≥ 100,000/mm3 * Neutrophils ≥ 1,500/mm3 * Serum creatinine ≤ 1.5 x upper limit of normal (ULN) * Urine protein creatinine (UPC) ratio \< 1 or urine dipstick for proteinuria ≤ 2+ * Alanine transaminase (ALT) \< 3 ULN * Aspartate transaminase (AST) \< 3 x ULN * Prothrombin time ≤ 1.2 x ULN * International Normalized Ratio (INR) \< 1.5 * Bilirubin \< 2 x ULN 12. Patients with the region of interest (ROI) for FUS exposure are located close to the cortex with at least 20 mm distance beneath the skull bone and the ROI is not in the deep center brain with crucial brain functions, such as in the region of brain stem, or motor or speech regions 13. Patients with the potential for pregnancy and their partner must agree to use adequate contraception or be surgically sterile, or abstain from heterosexual activity starting with the first dose of treatment through at least 6 months after the last dose of BEV to avoid conception. Female patients of child-bearing potential must have a negative pregnancy test. Male patients must agree to use an adequate method of contraception starting with the first dose of treatment through 6 months after the last dose of BEV. 14. Able to give informed consent for the participation in the trial Exclusion Criteria: 1. Patients who have had previous treatment with an inhibitor of vascular endothelial growth factor (VEGF) or VEGFR (including bevacizumab) 2. New York Heart Association (NYHA) Grade II or greater congestive heart failure requiring hospitalization within 12 months prior to screening 3. Severe hypertension at screening (diastolic blood pressure \> 100 mmHg on medication) 4. Uncontrolled intercurrent illness including, but not limited to symptomatic congestive heart failure, unstable angina pectoris, severe cerebral or myocardial infarction, cardiac shunt, heart attack within the previous 12 months, stroke (except for transient ischemic attack; TIA) within the previous 6 months, or psychiatric illness/social situations that would limit compliance with study requirements 5.

Known HIV positive patients, however, that HIV testing is not required for entry into this study 9. Acute bacterial or fungal infection requiring intravenous antibiotics at the time of screening 10. Receiving anticoagulant (e.g. warfarin) or antiplatelet (e.g. aspirin) therapy within one week prior to beginning treatment 11. Pregnant or breast-feeding women 12. Known sensitivity/allergy to PET tracers, Magnetic Resonance Imaging (MRI) contrast agents, Computer Tomography (CT) contrast agents, SonoVue®, bevacizumab, or any of their components 13. Abnormal baseline findings considered by the investigator to indicate conditions that might affect study endpoints 14. Patients who have hemorrhage or cyst within the ROI 15. The receipt of an investigational drug within a period of 4 weeks prior to the first FUS exposure 16. Use of any recreational drugs or history of drug addiction 17. Any other condition that, in the investigator's judgment, might increase the risk to the patients or decrease the chance of obtaining satisfactory data needed to achieve the objectives of the study
