Radiologic Pathologic Correlation of Imaging to Distinguish True Progression From Pseudoprogression in Brain Malignancies

Radiologic Pathologic Correlation of Imaging to Distinguish True Progression From Pseudoprogression in Brain Malignancies (NCT06199479) is a Phase 1 interventional studying Brain Malignancies and Pseudoprogression, sponsored by M.d. Anderson Cancer Center. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Brain Malignancies, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 25 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

Who May Qualify: 1. Participants is \>18 years old. The pediatric population has a different disease profile from adult glioma participants. To reduce heterogeneity in the patient population we will not consider participants younger than 18 for this study. 2. The participants agrees to participate in the clinical study and to complete all required visits and evaluations. 3. Participants has undergone prior treatment for a brain tumor and has a new suspicious imaging finding requiring diagnostic workup and is being considered for biopsy. 4. Participants agrees to undergo, prior to the procedure, the needed imaging evaluation (within 14 days and preferably with 3 days of the planned procedure). Who Should NOT Join This Trial: 1. Renal failure as evidenced by a GFR of less than 30 mL/min/1.73m2 for gadolinium based imaging. In the absence of eGFR lab result, participants is not excluded in the absence of remarkable pathological renal history, as confirmed by and in the discretion of the PI. 2. For iodinated contrast agent we will use the more strict cut-off of 45 mL/min/1.73m2 ((Davenport, Perazella et al. 2020), Consensus statement from the ACR and the National Kidney Foundation). The different threshold reflects the different risk profiles of these agents. Participants with GFR in the range 30-45 can receive a Non-Contrast DECT (CT contrast withheld). 3. Pacemakers, electronic stimulation, metallic foreign bodies and devices and/or other conditions that are not MR safe, which include but are not limited to: - electronically, magnetically, and mechanically activated implants - ferromagnetic or electronically operated active devices like automatic cardioverter defibrillators and cardiac pacemakers - metallic splinters in the eye - ferromagnetic hemostatic clips in the central nervous system (CNS) or body - cochlear implants - other pacemakers, e.g., for the carotid sinus - insulin pumps and nerve stimulators - non-MR safe lead wires ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

Nonetheless, if patients have an electronic device for which manufacturer's guidelines exist to permit safe MR scanning (such as the Cardiology supervised pacemaker scanning program), such a patient would still be eligible to participate in the trial. Such patients will be scanned as per manufacturers recommendations. 4. Allergy to relevant imaging contrast agents, includes allergies to iodine or gadolinium-based contrast agents (if one class of agents is contra-indicated, then imaging with the other can still proceed).

How to Talk to Your Doctor About This Trial

Bring the printable summary of this trial — including the NCT ID (NCT06199479), the sponsor (M.d. Anderson Cancer Center), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?

Frequently Asked Questions

What is the NCT06199479 clinical trial studying?

To learn if advanced imaging methods can tell apart true progression (the disease has actually gotten worse) from pseudoprogression (the disease appears to have gotten worse, but it actually has not). The full protocol is registered on ClinicalTrials.gov and includes the primary outcome measures, eligibility criteria, and study endpoints.

Who can participate in NCT06199479?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

How do I contact the trial site for NCT06199479?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
