ARCC-4 is a low-nanomolar androgen receptor (AR) degrader based on PROTAC, with a DC50 of 5 nM. ARCC-4 is an enzalutamide-based von Hippel-Lindau (VHL)-recruiting AR PROTAC and outperforms enzalutamide. ARCC-4 effectively degrades clinically relevant AR mutants associated with antiandrogen therapy[1].
ARCC-4 induces apoptosis and inhibiting proliferation of AR-amplified prostate cancer cells[1].ARCC-4 enhances protein-protein interactions between AR and VHL, thereby promoting the association of the trimeric complex[1].ARCC-4 (0.1-10,000 nM; 20 hours) potently degrades AR with a D50 of 5 nM and Dmax of over 95%[1].ARCC-4 (100 nM; 12 hours) shows near complete AR degradation (>98%) in prostate cancer cells[1]. ARCC-4 selectively degrades AR via the proteasome but not PR-A or PR-B suppression[1].ARCC-4 shows efficacy against clinically relevant AR mutations[1].ARCC-4 maintains activity despite elevated androgen levels[1].

Androgen receptor degradation by the proteolysis-targeting chimera ARCC-4 outperforms enzalutamide in cellular models of prostate cancer drug resistance
Commun Biol 2018 Aug 2;1:100.PMID:30271980DOI:10.1038/s42003-018-0105-8.
The androgen receptor is a major driver of prostate cancer and inhibition of its transcriptional activity using competitive antagonists, such as enzalutamide remains a frontline therapy for prostate cancer management. However, the majority of patients eventually develop drug resistance. We propose that targeting the androgen receptor for degradation via Proteolysis Targeting Chimeras (PROTACs) will be a better therapeutic strategy for targeting androgen receptor signaling in prostate cancer cells. Here we perform a head-to-head comparison between a currently approved androgen receptor antagonist enzalutamide, and its PROTAC derivative, ARCC-4, across different cellular models of prostate cancer drug resistance. ARCC-4 is a low-nanomolar androgen receptor degrader able to degrade about 95% of cellular androgen receptors. ARCC-4 inhibits prostate tumor cell proliferation, degrades clinically relevant androgen receptor point mutants and unlike enzalutamide, retains antiproliferative effect in a high androgen environment. Thus, ARCC-4 exemplifies how protein degradation can address the drug resistance hurdles of enzalutamide.
Solubility Enhanced Formulation Approaches to Overcome Oral Delivery Obstacles of PROTACs
Pharmaceutics 2023 Jan 3;15(1):156.PMID:36678785DOI:10.3390/pharmaceutics15010156.
PROteolysis TArgeting Chimaeras (PROTACs) offer new opportunities in modern medicine by targeting proteins that are undruggable to classic inhibitors. However, due to their hydrophobic structure, PROTACs typically suffer from low solubility, and oral bioavailability remains challenging. At the same time, due to their investigative state, the drug supply is meager, leading to limited possibilities in terms of formulation development. Therefore, we investigated the solubility enhancement employing mini-scale formulations of amorphous solid dispersions (ASDs) and liquisolid formulations of the prototypic PROTAC ARCC-4. Based on preliminary supersaturation testing, HPMCAS (L Grade) and Eudragit® L 100-55 (EL 100-55) were demonstrated to be suitable polymers for supersaturation stabilization of ARCC-4. These two polymers were selected for preparing ASDs via vacuum compression molding (VCM), using drug loads of 10 and 20%, respectively. The ASDs were subsequently characterized with respect to their solid state via differential scanning calorimetry (DSC). Non-sink dissolution testing revealed that the physical mixtures (PMs) did not improve dissolution. At the same time, all ASDs enabled pronounced supersaturation of ARCC-4 without precipitation for the entire dissolution period. In contrast, liquisolid formulations failed in increasing ARCC-4 solubility. Hence, we demonstrated that ASD formation is a promising principle to overcome the low solubility of PROTACs.
