Evaluation of Diagnostic Performances of 18F-FDOPA PET KInetics as Biomarkers for the Improvement of Care of MRI Non-contrast Enhanced Gliomas

the investigators hypothesise that 18F-FDOPA PET kinetic parameters are good biomarkers to characterise suspected LGG brain lesions that exhibit no contrast on MRI, for identifying aggressive lesions. These parameters could constitute diagnostic biomarkers for this indication. This new diagnostic tool could enhance patient care in the short term in an evolving pathology affecting socially active subjects with a poor prognosis

First-in-Human Assessment of Safety, Biodistribution and Pharmacokinetics of 18F-Fluoro-1-Naphthol (18F-4FN) for PET Imaging

18F-4FN represents a novel PET agent for imaging inflammation. Acute inflammatory signaling through the TLR axis recruits neutrophils and macrophages to inflammatory sites. Both cells activate the production of high energy reactive oxygen species/reactive nitrogen species (RONS), setting off a cascade that can be leveraged to detect the presence of these inflammatory cells by molecular imaging. 18F-4FN is efficiently oxidized by high energy RONS, leading to retention and accumulation in human neutrophil-like cells in vitro, and at the sites of acute inflammation in vivo. Like 18F-FDG, 18F-4FN clears rapidly through the kidney at 1 hr following i.v. injection

High Tumor Uptake on¹⁸F-FDOPA PET/CT Indicates Poor Prognosis in Patients with Metastatic Midgut Neuroendocrine Tumors: A Study from the Groupe d’étude des Tumeurs Endocrines and ENDOCAN-RENATEN Network

Article

作者: Cros, Jérôme ; Lebtahi, Rachida ; Lachachi, Choaib ; Taieb, David ; Cadiot, Guillaume ; Ouvrard, Éric ; Morland, David ; Bando-Delaunay, Aurélie ; Hentic, Olivia ; Perrier, Marine ; Imperiale, Alessio ; De Rycke, Ophélie ; de Mestier, Louis ; Goichot, Bernard ; Walter, Thomas ; Ruszniewski, Philippe ; Mennetrey, Clément

PET/CT with 6-¹⁸F-fluoro-l-dopa (¹⁸F-FDOPA) has high diagnostic performance for midgut neuroendocrine tumors (NETs). We explored the prognostic role of ¹⁸F-FDOPA PET/CT uptake in metastatic midgut NETs. Methods: We included, in a test cohort (n = 166) and a full external validation cohort (n = 86), all consecutive patients with metastatic midgut NETs who underwent ¹⁸F-FDOPA PET/CT in 5 expert centers from 2010 to 2021. We measured the maximal uptake (SUV_max and SUV_peak) of the tumor and nontumor liver on each ¹⁸F-FDOPA PET/CT scan. We measured overall survival (OS) from the time of PET/CT and assessed prognostic factors using Kaplan-Meier and multivariable Cox proportional-hazards analyses in the test cohort, with replication in the validation cohort. Results: Patients had similar characteristics in both cohorts. In the test cohort, median follow-up was 60.3 mo. Patients with an SUV_peak tumor-to-liver (T/L) ratio of more than 4.2 had significantly shorter survival than those with a ratio of 4.2 or less (P = 0.01), with a 5-y OS rate of 74.1% ± 4.5% versus 95% ± 3.4%, respectively. On multivariable analysis, an SUV_peak T/L ratio of more than 4.2 remained associated with shorter OS (hazard ratio, 2.30; 95% CI, 1.02-5.22; P = 0.046) after adjustment for age, grade, number of previous lines, number of metastatic sites, and presence of carcinoid syndrome. In the validation cohort, the 5-y OS rate was 100% versus 57.8% ± 12.5% in patients with an SUV_peak T/L ratio ≤ 4.2 or > 4.2, respectively (P = 0.075). An increasing SUV_peak T/L ratio over time tended to have a pejorative prognostic impact. Conclusion: Tumor uptake on ¹⁸F-FDOPA PET/CT is an independent prognostic factor in patients with metastatic midgut NETs.

Discriminating Inflammatory Radiation-Related Changes From Early Recurrence in Patients With Glioblastomas: A Preliminary Analysis of 68 Ga-PSMA-11 PET/CT Compared With 18 F-FDOPA PET/CT.

Article

作者: Khayi, Fouzi ; Ducray, François ; Kryza, David ; Bonneville-Levard, Alice ; Maureille, Aurélien ; Larrouquere, Louis ; Moreau, Aurélie

PURPOSE OF THE REPORT:

Using morphological and functional imaging to discriminate recurrence from postradiation-related modifications in patients with glioblastomas remains challenging. This pilot study aimed to assess the feasibility of using 68 Ga-prostate-specific membrane antigen (PSMA) 11 PET/CT compared with 18 F-FDOPA PET/CT to detect early recurrence.

METHODS:

Nine patients followed up for glioblastomas who received MRI during 12 months of follow-up were referred for both 68 Ga-PSMA-11 and 18 F-FDOPA PET/CT. The SUV max , lesion-to-striatum ratio, lesion-to-normal parenchyma ratio, and lesion-to-salivary gland ratio were calculated.

RESULTS:

Good correlation between 18 F-FDOPA and 68 Ga-PSMA PET/CT findings was seen in 5 patients. In 4 patients, the findings of both examinations were consistent with recurrence but were better visualized with the PSMA PET/CT. Examinations of the fifth patient were suggestive of postradiation-related changes and were better analyzed with the PSMA PET/CT, which displayed relatively low uptake compared with DOPA PET/CT. Conversely, 4 patients showed conflicting results: recurrence was not detected on the PSMA PET/CT because of previously introduced bevacizumab treatment; in another patient, both examinations were consistent with recurrence, but there was an uptake mismatch at the suspected lesion sites, and 2 patients presented with inconsistent findings.

CONCLUSIONS:

Despite a few discrepancies, this study highlights the potential role of 68 Ga-PSMA-11 PET/CT for discriminating postradiation inflammation from recurrence. 68 Ga-PSMA-11 PET/CT has an excellent lesion-to-background ratio, and false-positive and false-negative results could be minimized through implementing certain protocols before performing the examination. More powerful prospective studies are required to validate our results.

Comparison of [18F]DOPA and [68Ga]DOTA-TOC as a PET imaging tracer before peptide receptor radionuclide therapy

Article

作者: de Groot, Derk Jan A ; Veenstra, Emile B ; Noordzij, Walter ; Zandee, Wouter T ; Brabander, Tessa ; Brouwers, Adrienne H ; Hofland, Johannes ; Walenkamp, Annemiek M E

Abstract:

Background:

In treatment of neuroendocrine neoplasms (NENs), confirmation of somatostatin receptor expression with 68Ga-DOTA somatostatin analogues is mandatory to determine eligibility for peptide receptor radionuclide therapy (PRRT). [18F]DOPA can detect additional lesions compared to [68Ga]DOTA-TOC. The aim of this study was to explore differences in tumour detection of both tracers and their relevance for selecting patients for PRRT. We retrospectively studied eight patients with NENs who underwent both [68Ga]DOTA-TOC and carbidopa-enhanced [18F]DOPA PET/CT, before first-time PRRT with [177Lu]DOTA-TATE. Tracer order was influenced due to stock availability or to detect suspected metastases with a second tracer. On CT, disease control was defined as a lesion showing complete response, partial response, or stable disease, according to RECIST 1.1. criteria.

Results:

Seven patients with in total 89 lesions completed four infusions of 7.4 GBq [177Lu]DOTA-TATE, one patient received only two cycles. Before treatment, [18F]DOPA PET/CT detected significantly more lesions than [68Ga]DOTA-TOC PET/CT (79 vs. 62, p < .001). After treatment, no difference in number of lesions with disease control was found for [18F]DOPA-only (5/27) and [68Ga]DOTA-TOC-only lesions (4/10, p = .25). [18F]DOPA detected more liver metastases (24/27) compared to [68Ga]DOTA-TOC (7/10, p = .006). Six patients showed inpatient heterogeneity in treatment response between [18F]DOPA-only and [68Ga]DOTA-TOC-only lesions.

Conclusions:

Response to PRRT with [177Lu]DOTA-TATE was comparable for both [68Ga]DOTA-TOC- and [18F]DOPA-only NEN lesions. [18F]DOPA may be capable of predicting response to PRRT while finding more lesions compared to [68Ga]DOTA-TOC, although these additional lesions are often small of size and undetected by diagnostic CT.

FDA grants RMAT status for BlueRock’s Parkinson’s therapy

Bemdaneprocel is created to replace the dopamine-producing neurons lost due to Parkinson’s disease. Credit: Annick Vanblaere from Pixabay. The US Food and Drug Administration (FDA) has granted a regenerative medicine advanced therapy (RMAT) designation for BlueRock Therapeutics’ investigational cell therapy bemdaneprocel (BRT-DA01) for Parkinson’s disease. Recommended Buyer's Guides Buyer's Guide Leading Guide to Packaging Materials, Containers and Containment Services for the Pharmaceutical Industry Buyer's Guide Top Guide for Drug Delivery Systems BlueRock is a wholly owned independently operated Bayer subsidiary. Bemdaneprocel is claimed to be the most clinically advanced cell therapy for Parkinson’s disease treatment in the US. The therapy is created to replace the dopamine-producing neurons lost in the course of the disease. It was assessed in the multi-site, multicentre, non-randomised, open-label, non-controlled study. See Also: Dupixent gets closer to EU approval as the FDA delays its decision on COPD Bristol Myers Squibb’s Breyanzi gains FDA approval for lymphoma The trial involved 12 subjects diagnosed with Parkinson’s disease who underwent surgical transplantation of bemdaneprocel cells into the post-commissural putamen bilaterally, followed by a one-year immunosuppression regimen. Data from the trial, announced in March 2024, indicated that bemdaneprocel was well tolerated and did not present major safety issues up to 18 months post-treatment. Furthermore, an increase in the F-DOPA PET imaging signal was observed after the cessation of immune suppression therapy at 12 months, suggesting that the transplanted cells survive and engraft in the brain. The RMAT designation is managed by the FDA’s Center for Biologics, Evaluation and Research (CBER). It is specifically for investigational regenerative therapies, including cell therapies, aimed at treating, modifying, reversing or curing serious ailments. Therapies granted RMAT status can benefit from expedited development review and development planning guidance from senior CBER managers. This status also facilitates early discussions about possible surrogate endpoints and strategies to support accelerated approval and satisfy post-approval needs. BlueRock Therapeutics president and CEO Seth Ettenberg stated: “We are excited about the positive data from the bemdaneprocel Phase I clinical trial and believe it has great potential to help patients living with Parkinson’s disease regain functions they have lost to the disease. “Now with this RMAT designation in hand, we look forward to closely collaborating with the FDA to ready this programme for Phase II clinical studies.” Cell & Gene Therapy coverage on Pharmaceutical Technology is supported by Cytiva .
