Structural insights into the substrate uptake and inhibition of the human creatine transporter (hCRT).
(PubMed, Proc Natl Acad Sci U S A)
- "Creatine is coordinated in the central substrate-binding site through interactions with transmembrane helices TM1, TM3, TM6, and TM8, while the inhibitor RGX202 occupies the same binding pocket, engaging in overlapping contacts that competitively block creatine access. Our structural and mechanistic findings clarify substrate recognition and inhibitory binding of hCRT, providing a molecular rationale for targeting hCRT in both inherited metabolic diseases and cancer therapy."

Hypoxia-Induced Creatine Uptake Reprograms Metabolism to Antagonize PARP1-Mediated Cell Death and Facilitate Tumor Progression in Hepatocellular Carcinoma.
(PubMed, Cancer Res)
- "The SLC6A8 inhibitor RGX-202 exerted potent antitumor activity alone and in combination with lenvatinib in patient-derived xenografts and primary HCC mouse models. Overall, this study identified intracellular creatine accumulation as a mechanism that allows hypoxic cancer cells to circumvent parthanatos and as a therapeutic target in HCC."

A randomized blinded phase II study of ompenaclid (RGX-202-01) vs placebo in combination with FOLFIRI plus bevacizumab (BEV) in patients (pts) with previously treated RAS mutated (RASmt) advanced/metastatic colorectal cancer (mCRC)
(ESMO 2024)
- P2 | "In an open-label single arm study (RGX-202-001) as 2L treatment in pts with RASmt mCRC, ompenaclid at 2400 mg and 3000 mg orally twice-daily (BID) in combination with FOLFIRI/BEV was shown to have potential clinical benefit with a tolerable safety profile (ESMO 2023, abstract 646P).Trial design: Key eligibility criteria: measurable disease per RECIST v1.1, disease progression after 1L oxaliplatin-based therapy and ECOG performance status 0–1. Treatment consists of FOLFIRI/BEV (irinotecan intravenously [IV] 180 mg/m2, 5-FU 46-hour IV 2400 mg/m2, leucovorin IV 400 mg/m2, BEV IV 5 mg/kg every 2 weeks), with double-blind 1:1 randomization to either ompenaclid 3000 mg PO BID or placebo, stratified by prior exposure to 1L BEV...The study will enroll 70 pts and is conducted in Spain, Belgium and France. Study enrollment is ongoing."

(ESMO 2024)
- P1 | "Pts must have had progression after a 1L oxaliplatin-containing regimen... Ompenaclid + FOLFIRI/BEV was well tolerated. Encouraging efficacy was observed in pts with RASmt mCRC, with ORR, mPFS and mOS exceeding that expected with standard of care. This preferential RASmt activity is consistent with preclinical and Ph 1a data."

Anti-tumor efficacy of ompenaclid, a creatine transporter inhibitor, in KRAS mutant tumors, including NSCLC
(AACR 2024)
- "Ompenaclid is currently in a Phase 2 trial, in combination with FOLFIRI and bevacizumab, in patients with RAS-mutated second-line advanced/metastatic colorectal cancer...Combination treatment with MRTX849, a KRAS G12C inhibitor, was conducted in a pancreatic MiaPaca xenograft model. Our studies demonstrate ompenaclid anti-tumor efficacy in NSCLC and pancreatic xenografts... Our studies demonstrate ompenaclid anti-tumor efficacy in NSCLC and pancreatic xenografts. Notably, and consistent with findings in CRC, efficacy in NSCLC was more robust in RAS mutant cancer models, relative to those bearing KRAS WT tumors. Metabolite analysis of the plasma of tumor-bearing mice at baseline revealed that mice harboring RAS mutant tumors had higher levels of p-creatine and lower levels of ATP, indicating that RAS mutant tumors utilize higher amounts of ATP, which may be converted to phosphocreatine by tumoral CKB, as confirmed by qPCR analysis."
