The potential of ARL4C and its-mediated genes in atherosclerosis and agent development.
(PubMed, Front Pharmacol)
- "Many agents, including ABCA1 agonists (CS-6253, IMM-H007, RG7273, and R3R-01), FLNA antagonist sumifilam, LRP6 inhibitor BI-905677 and agonist SZN-1326, and SOX2 inhibitor STEMVAC, were investigated in clinical trials. Thus, ARL4C and its regulated genes may be a potential target for drug development. Thus, we focus on the role of ARL4C and its-mediated genes in atherosclerosis and agent development, which provide insights for the identification, research, and drug development of novel targets."

RESULTS FROM THE PHASE 1 SAD-MAD STUDY OF THE ATP BINDING CASSETTE A1 AGONIST CS6253, DEVELOPED FOR THE INDICATION OF APOE4-ASSOCIATED DEMENTIA INCLUDING MCI-AD
(ADPD 2025)
- P1 | "A single CS6253 (n=18) vs. placebo (n=6) dose increased CSF Aβ42 (active 53.68% vs. placebo -24.59%) and Aβ40 (active 62.45% vs. placebo -8.07%) with p-values of 0.16 and 0.02, respectively, with the Aβ42/40 ratio nominally increased. Conclusions The CS6253 Phase 1 SAD-MAD trial in HV, including elderly showed excellent safety, tolerance, PK and trends for brain amyloid-clearance to CSF pointing to CS6253 as a safe and efficient ABCA1-agonist with potential in addressing unmet medical need including Alzheimer's disease."

A novel apoE-mimetic increases brain apoE levels, reduces Aβ pathology and improves memory when treated before onset of pathology in male mice that express APOE3.
(PubMed, Alzheimers Res Ther)
- "CS treatment reduced Aβ pathology and improved memory only in young male E3FAD, the cohort with the least AD pathology. Therefore, the degree of Aβ pathology or Aβ overproduction may impact the ability of targeting ABCA1 to be an effective AD therapeutic. This suggests that ABCA1-stabilizing treatment by CS-6253 works best in conditions of modest Aβ levels."

Mechanisms of reduced Apolipoprotein E4 lipidation in iPSC-derived astrocytes
(AAIC 2023)
- "The protein levels of ABCA1, which mediates cholesterol and phospholipid efflux to the nascent apolipoprotein particles, were lower in APOE4/4 iPSC-derived astrocytes compared to astrocytes derived from isogenic APOE3/3 iPSCs. Advanced image analysis revealed lower ABCA1 protein levels in Rab11 + recycling endosomes and less colocalization between ABCA1 and Rab7, a late endosome marker, in APOE4/4 astrocytes than APOE3/3 astrocytes. Consequently, less ABCA1 was detected at the cell membrane."

Design of the ABCA1 agonist CS6253 Phase 1 SAD and MAD study in male and female, APOE4 and non-APOE4 carriers to assess safety, PK and biomarker efficacy
(CTAD 2022)
- "The Phase 1 SAD and MAD study of the ABCA1 agonist CS6253 treatment will evaluate safety, PK and biomarker efficacy in male and female subjects with and w/o APOE4. Simultaneous collection and analysis in plasma and CSF of PK and of PD markers including apoE and Ab42/40- ratio will assess clinical potential for this cholesterol-targeting treatment of hereditary APO4-associated AD."

[VIRTUAL] CS6253 ABCA1 AGONIST IN CYNOMOLGUS MONKEYS INCREASE APOA-I SUBSPECIES PREβ-HDL AND LOWERS Aβ42 AND Aβ40 IN CEREBRO SPINAL FLUID
(AAIC 2021)
- "The CS6253 ABCA1 agonist transiently increases plasma preβ-HDL and reduces CSF concentrations of Aβ42 and Aβ40. The Aβ reduction is consistent with apoE targeted replacement mice models studies where CS6253 reduced Aβ42, prevented AD brain pathology and improved cognition. Studies in human APOE ε4 carriers with and without AD are needed to corroborate these findings and to investigate the therapeutic potential of CS6253 or similar compounds."

[VIRTUAL] CS6253 ABCA1 AGONIST TREATMENT IN JUVENILE CYNOMOLGUS MONKEYS REDUCES CSF AΒ42 AND INCREASES PLASMA AΒ42 IN DOSE-RESPONSE MANNER
(ADPD 2021)
- "CSF and plasma Aβ42 and Aβ40 were analyzed by SIMOA, CSF APP and amyloid protein complex2B1 (AP2B1) by mass spectrometry. Results CS6253 treatment decreased CSF levels of Aβ42, Aβ40, APP and AP2B1 and increased plasma Aβ42, Aβ40, both following dose-response pattern, see Figures. Conclusions The CS6253 ABCA1 agonist reductions of Aβ42, Aβ40, APP and AP2B1 in CSF of juvenile cynos are consistent with previous finding in apoE4 mice models where brain Aβ42 (and P-tau) was reduced, AD pathology was prevented, and cognition improved. Studies in human APOE ε4 carriers are needed to corroborate these findings."

(CTAD 2020)
- "Compared to placebo, the ABCA1 agonist CS6253 reduced CSF Aβ42, Aβ40, APP and AP2B1 in dose-response manner in the 2 year old cynos. The results are consistent with previous finding in APOE4 mice models where brain Aβ42 (and P-tau) was reduced, AD pathology prevented, and cognition improved. The results need to be corroborated in humans with and without APOE ε4 at therapeutic doses."

[VIRTUAL] APOE4 ALTERS ABCA1 MEMBRANE TRAFFICKING AND DECREASE AΒ42 DEGRADATION IN ASTROCYTES WHICH IS COUNTERACTED BY ABCA1-AGONIST CS6253
(AAT-ADPD 2020)
- "Conclusions Aggregated and lipid-poor ApoE4 increases ABCA1 aggregation and decreases ABCA1 cell membrane recycling which is countered by CS6253 ABCA1 upregulation. Enhancing ABCA1 activity to reduce ApoE and ABCA1 aggregation is a potential therapeutic strategy for the prevention of ApoE4-driven pathology."

Ongoing subchronic non-human primate studies collecting plasma, CSF and brain will further discern the apoA-I transfer properties to brain conveyed by ABCA1 CS6253 and the feasibility of increasing brain apoA-I in reversing apoE4 associated dementia."
