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 This study
Running, but no longer taking on new participants.
Completed
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 early study tests a new radioactive drug called [18F] Fluoroglutamine, which is designed to be used with PET scanners. Researchers want to see how long it stays in the blood and where it goes in the body, especially whether it collects in tumors. 67 adults with solid cancers or lymphoma will receive a small injection and then have PET scans. The goal is to gather safety and imaging data, not to treat the cancer.

What this could mean

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

Active substance
[18F] 4-L-Fluoroglutamine (2S,4R) (a radioactive tracer for PET scans)
What this could lead to
If successful, this could lead to a new way to spot tumors using PET scans, potentially improving cancer detection.
What could go wrong
This is a very early Phase I study with only 67 people, focused on safety and imaging, not on treating cancer. It may not prove better than current scans.

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

Inclusion Criteria: * Patients with history of histologically-confirmed solid malignancy and/or lymphoma (histology confirmed by MSKCC Department of Pathology.) Disease measurable or evaluable as defined by RECIST 1.1 or other tumor response criteria from an MSKCC IRB-approved clinical research protocol. NOTE: Study patients do not need to be participating in an MSKCC approved clinical trial prior to study recruitment. * Age between 21-90 * Negative serum pregnancy test for female patients of childbearing age and potential (as defined by MSKCC Standards \& Guidelines), from assays obtained \<2 weeks prior to study enrollment. Patients will be advised against having unprotected sexual intercourse from the time of the negative serum pregnancy test until after completing their participation in the study. Exclusion Criteria: * Inability or refusal to have at least one peripheral intravenous line for intravenous access (as applicable to the day of \[18F\] 4-L-Fluoroglutamine (2S,4R) injection and blood draws.) * Breast-feeding * Refusal or inability to tolerate the scanning procedure (e.g., due to claustrophobia) * Hepatic: from assays obtained \<2 weeks prior to study enrollment For each patient, the upper limit of normal (ULN) value for a particular assay will be defined by the normal reference values of the laboratory that performed the assay. * Bilirubin \> 1.5 x (ULN) * AST/ALT \>2.5 x ULN * Albumin \< 3 g/dl * GGT \> 2.5 x ULN IF Alkaline phosphatase \> 2.5 x ULN. * Renal: Creatinine \>1.5 x ULN or creatinine clearance \< 60 mL/min, from assays obtained \<2 weeks prior to study enrollment * Acute major illness (e.g., unstable cardiovascular condition, etc.)
