Cerenome Highlights Presentations at the 2026 SNO/ASCO CNS Metastases Conference Demonstrating Progress in Both Therapeutics and Diagnostics Business Lines
Rhea-AI Summary
Cerenome (Nasdaq: CNSY) reported new data from two posters at the 2026 SNO/ASCO CNS Metastases Conference covering its REYOBIQ™ radiotherapeutic program and CNSide® diagnostics-driven care model for leptomeningeal metastases (LM).
Updated ReSPECT-LM and ongoing ReSPECT-LMM results showed pharmacokinetic, pharmacodynamic and dosimetry findings for REYOBIQ, including rapid cerebrospinal fluid (CSF) redistribution, a 1.7-hour ventricular half-life, apoptosis gene induction within about 5 hours, and no dose-limiting toxicities in Cohort 1a of the repeated-dosing study. A separate CNSide cost-of-care model estimated average LM treatment costs at about $119,550 per month and suggested a CNSide-enabled pathway could reduce monthly LM-related costs by roughly 33–47% under modeled scenarios.
Positive
- Cohort 1a repeated dosing cleared with no dose-limiting toxicities
- REYOBIQ PK showed ~24-hour CSF redistribution and 1.7-hour ventricular half-life
- Apoptosis gene activity induced by ~5 hours with peak at 24 hours
- Baseline LM treatment costs estimated at ~$119,550 per month
- CNSide-enabled pathway modeled 33–47% monthly LM cost reductions
Negative
- None.
News Explained
The disclosure remains an interim clinical update: Cohort 1a of the ongoing repeated-dosing ReSPECT-LMM study had no dose-limiting toxicities, while enrollment continues in additional cohorts.

HOUSTON, Aug. 20, 2026 (GLOBE NEWSWIRE) -- Cerenome, Inc. (Nasdaq: CNSY) (“Cerenome” or the “Company”) today highlights data from two scientific posters presented at the 2026 Society for Neuro-Oncology/American Society of Clinical Oncology (SNO/ASCO) CNS Metastases Conference, held August 13–15 in Boston. One presentation featured updated pharmacokinetic (PK), pharmacodynamic (PD), dosimetry, safety and activity data for REYOBIQ™ (rhenium-186 obisbemeda) in patients with leptomeningeal metastases (LM), including emerging safety data from the ongoing repeated-dosing program. The second was an update of a previously reported health economics analysis evaluating the impact of CNSide®-enabled earlier LM detection and therapeutic management.
“The data presented at SNO/ASCO underscore the rationale behind Cerenome’s integrated approach to leptomeningeal metastases – from earlier and more definitive detection and quantitative disease monitoring with CNSide, to targeted local therapy with REYOBIQ,” said Marc H. Hedrick, M.D., Cerenome President and Chief Executive Officer. “The REYOBIQ findings provide additional support for broad CSF distribution, limited systemic exposure in most patients, and the continued evaluation of repeat dosing. The CNSide analysis reinforces the potential economic value of earlier, information-rich disease management. Together, these data demonstrate the potential of connecting diagnostics, therapeutics and longitudinal data to improve the management of CNS cancers.”
As previously announced, both posters will be available on the Publications page of Cerenome’s website following the conclusion of the conference.
REYOBIQ ReSPECT-LM and ReSPECT-LMM Data
A poster titled, “ReSPECT-LM: Pharmacokinetic and Pharmacodynamic Assessment of Rhenium Obisbemeda in Leptomeningeal Metastases with Emerging Data from Repeated Dosing (ReSPECT-LMM)” was presented by Andrew Brenner, M.D., Ph.D., of The University of Texas Health Science Center at San Antonio. The analysis included updated safety, activity, PK and dosimetry findings from the single-administration study, along with emerging data from the ongoing repeated-dosing program.
Key findings included:
- In the ongoing repeated-dosing ReSPECT-LMM study, Cohort 1a cleared with no dose-limiting toxicities, with enrollment ongoing in additional cohorts.
- PK showed rapid ( ̴24 hours) redistribution of drug within the CSF with clearance of the REYOBIQ from the lateral ventricle at a half-life of 1.7 hours. By clearing the ventricles quickly, drug remains available at high doses in the cerebral spinal fluid.
- Bulk RNA-Seq demonstrated rapid ( ̴5 hours) induction of cell-death (apoptosis) genes, with peak activity occurring at 24 hours. Data promoting cell-death supports REYOBIQ’s established radiopharmaceutical mechanism of action and highlights its rapid onset target activity.
CNSide Cost-of-Care Analysis
The second poster, titled, “Economic Impact of Earlier Detection and Therapeutic Management of Leptomeningeal Metastases Using CNSide®: A Cost-of-Care Analysis,” was presented by Kelly Kreitzburg Ondrasek, Ph.D., Medical Science Liaison at CNSide Diagnostics. The analysis evaluated the potential economic and clinical impact of a CNSide-enabled care pathway incorporating earlier definitive LM diagnosis, targeted treatment, and quantitative disease monitoring.
The model estimated average LM-related treatment costs of approximately
