Phase Ib/II study of ompenaclid (RGX-202-01), afirst-in-class oral inhibitor of the creatine transporter SLC6A8, in combination with FOLFIRI and bevacizumab (BEV) in RAS mutated (RASm) second-line (2L) advanced/metastatic colorectal cancer (mCRC) (ESMO 2023)
Eligible pts had disease progression after a 1L oxaliplatin-containing regimen...There is a high unmet need for a safe and combinable oral pan-RASm therapy in mCRC. Recruitment of RASm pts continues and a randomized controlled trial in 2L RASm mCRC is planned.

Tumour-derived small extracellular vesicles suppress CD8+ T cell immune function by inhibiting SLC6A8-mediated creatine import in NPM1-mutated acute myeloid leukaemia. (PubMed, J Extracell Vesicles)
Decreased creatine levels can reduce ATP production and impair CD8+ T cell immune function, leading to immune escape by leukemic cells. In summary, leukemic cell-derived sEV-related miR-19a-3p confers immunosuppression to CD8+ T cells by targeting SLC6A8-mediated creatine import, indicating that sEV-related miR-19a-3p might be a promising therapeutic target for NPM1-mutated AML.

SLC6A8-mediated intracellular creatine accumulation enhances hypoxic breast cancer cell survival via ameliorating oxidative stress. (PubMed, J Exp Clin Cancer Res)
Our study indicates that SLC6A8-mediated creatine accumulation plays an important role in promoting TNBC progression, and may provide a potential therapeutic strategy option for treatment of SLC6A8 high expressed TNBC.

Creatine promotes cancer metastasis through activation of Smad2/3. (PubMed, Cell Metab)
GATM knockdown or MPS1 inhibition suppresses cancer metastasis and benefits mouse survival by downregulating Snail and Slug. Our findings call for using caution when considering dietary creatine to improve muscle mass or treat diseases and suggest that targeting GATM or MPS1 prevents cancer metastasis, especially metastasis of transforming growth factor beta receptor mutant colorectal cancers.

SLC6A8 is involved in the progression of non-small cell lung cancer through the Notch signaling pathway. (PubMed, Ann Transl Med)
SLC6A8 promotes the malignant progression of NSCLC and activates the Notch signaling pathway. Therefore, SLC6A8 is expected to become a molecular target for NSCLC treatment.

[VIRTUAL] Phase I monotherapy dose escalation of RGX-202, a first-in-class oral inhibitor of the SLC6a8/CKB pathway, in patients with advanced gastrointestinal (GI) solid tumors. (ASCO 2020)
Among 17 patients treated with single agent therapy, no DLTs occurred; notably, exposures predicted to be sufficient to inhibit human tumor growth from preclinical models were achieved along with concomitant pharmacodynamic effects. These data, along with a durable PR observed in the highest dose cohort, support further development of RGX-202. Consequently, dose escalation in combination with FOLFIRI in patients with advanced GI cancers is underway with plans for expansion in CKB+ CRC pts.
