A disintegrin and metalloproteinase with thrombospondin motifs 5 (ADAMTS-5) is an aggrecanase in that it cleaves aggrecan, a major proteoglycan in cartilage. While it has key roles in cartilage destruction associated with osteoarthritis, ADAMTS-5 is also involved in other pathways, including neurological processes. ADAMTS-5 Inhibitor is an inhibitor of ADAMTS-5 (aggrecanase-2; IC50 = 1.1 µM) with 40-fold selectivity over ADAMTS-4 (aggrecanase-1).

Inhibition of MMPs and ADAM/ADAMTS
Biochem Pharmacol 2019 Jul;165:33-40.PMID:30826330DOI:10.1016/j.bcp.2019.02.033.
Matrix metalloproteinases (MMPs), A Disintegrin and Metalloproteinase (ADAM) and A Disintegrin and Metalloproteinase with Thrombospondin Motif (ADAMTS) are zinc-dependent endopeptidases that play a critical role in the destruction of extracellular matrix proteins and, the shedding of membrane-bound receptor molecules in various forms of arthritis and other diseases. Under normal conditions, MMP, ADAM and ADAMTS gene expression aids in the maintenance of homeostasis. However, in inflamed synovial joints characteristic of rheumatoid arthritis and osteoarthritis. MMP, ADAM and ADAMTS production is greatly increased under the influence of pro-inflammatory cytokines. Analyses based on medicinal chemistry strategies designed to directly inhibit the activity of MMPs have been largely unsuccessful when these MMP inhibitors were employed in animal models of rheumatoid arthritis and osteoarthritis. This is despite the fact that these MMP inhibitors were largely able to suppress pro-inflammatory cytokine-induced MMP production in vitro. A focus on ADAM and ADAMTS inhibitors has also been pursued. Thus, recent progress has identified the "sheddase" activity of ADAMs as a viable target and the development of GW280264X is an experimental ADAM17 inhibitor. Of note, a monoclonal antibody, GLPG1972, developed as an ADAMTS-5 Inhibitor, entered a Phase I OA clinical trial. However, the failure of many of these previously developed inhibitors to move beyond the preclinical testing phase has required that novel strategies be developed that are designed to suppress both MMP, ADAM and ADAMTS production and activity.
Exosite inhibition of ADAMTS-5 by a glycoconjugated arylsulfonamide
Sci Rep 2021 Jan 13;11(1):949.PMID:33441904DOI:10.1038/s41598-020-80294-1.
ADAMTS-5 is a major protease involved in the turnover of proteoglycans such as aggrecan and versican. Dysregulated aggrecanase activity of ADAMTS-5 has been directly linked to the etiology of osteoarthritis (OA). For this reason, ADAMTS-5 is a pharmaceutical target for the treatment of OA. ADAMTS-5 shares high structural and functional similarities with ADAMTS-4, which makes the design of selective inhibitors particularly challenging. Here we exploited the ADAMTS-5 binding capacity of β-N-acetyl-D-glucosamine to design a new class of sugar-based arylsulfonamides. Our most promising compound, 4b, is a non-zinc binding ADAMTS-5 Inhibitor which showed high selectivity over ADAMTS-4. Docking calculations combined with molecular dynamics simulations demonstrated that 4b is a cross-domain inhibitor that targets the interface of the metalloproteinase and disintegrin-like domains. Furthermore, the interaction between 4b and the ADAMTS-5 Dis domain is mediated by hydrogen bonds between the sugar moiety and two lysine residues (K532 and K533). Targeted mutagenesis of these two residues confirmed their importance both for versicanase activity and inhibitor binding. This positively-charged cluster of ADAMTS-5 represents a previously unknown substrate-binding site (exosite) which is critical for substrate recognition and can therefore be targeted for the development of selective ADAMTS-5 inhibitors.
Safety, Pharmacokinetics, and Pharmacodynamics of the ADAMTS-5 Inhibitor GLPG1972/S201086 in Healthy Volunteers and Participants With Osteoarthritis of the Knee or Hip
Clin Pharmacol Drug Dev 2022 Jan;11(1):112-122.PMID:34859612DOI:10.1002/cpdd.1042.
GLPG1972/S201086 is a disintegrin and metalloproteinase with thrombospondin motif-5 (ADAMTS-5) inhibitor in development as an osteoarthritis disease-modifying therapy. We report the safety, tolerability, pharmacokinetics, and pharmacodynamics (turnover of plasma/serum ARGS-aggrecan neoepitope fragments [ARGS]) of GLPG1972 in 3 randomized, double-blind, placebo-controlled phase 1 trials. Study A, a first-in-human trial of single (≤2100 mg [fasted] and 300 mg [fed]) and multiple (≤1050 mg once daily [fed]; 14 days) ascending oral (solution) doses, investigated GLPG1972 in healthy men (N = 41; NCT02612246). Study B investigated multiple ascending oral (tablet) doses of GLPG1972 (≤300 mg once daily [fed]; 4 weeks) in male and female participants with osteoarthritis (N = 30; NCT03311009). Study C investigated single (Japanese: ≤1500 mg; White: 300 mg [fasted]) and multiple (Japanese, ≤1050 mg once daily; White, 300 mg once daily [fed]; 14 days) ascending oral (tablet) doses of GLPG1972 in healthy Japanese and White men (N = 88). The pharmacokinetic profile of GLPG1972 was similar between healthy participants and participants with osteoarthritis, with low to moderate interindividual variability. GLPG1972 was rapidly absorbed (median time to maximum concentration, 4 hours), and eliminated with a mean apparent terminal elimination half-life of ≈10 hours. Steady state was achieved within 2 days of dosing, with minimal accumulation. Steady-state plasma exposure after 300 mg of GLPG1972 showed no or minor differences between populations. Area under the plasma concentration-time curve (56.8-67.6 μg · h/mL) and time to maximum concentration (4 hours) were similar between studies. Urinary excretion of GLPG1972 (24 hours) was low (<11%). Multiple dosing significantly reduced ARGS levels vs baseline at all time points for all doses vs placebo. GLPG1972 was generally well tolerated at all doses.
Discovery of GLPG1972/S201086, a Potent, Selective, and Orally Bioavailable ADAMTS-5 Inhibitor for the Treatment of Osteoarthritis
J Med Chem 2021 Mar 25;64(6):2937-2952.PMID:33719441DOI:10.1021/acs.jmedchem.0c02008.
There are currently no approved disease-modifying osteoarthritis (OA) drugs (DMOADs). The aggrecanase ADAMTS-5 is key in the degradation of human aggrecan (AGC), a component of cartilage. Therefore, ADAMTS-5 is a promising target for the identification of DMOADs. We describe the discovery of GLPG1972/S201086, a potent and selective ADAMTS-5 Inhibitor obtained by optimization of a promising hydantoin series following an HTS. Biochemical activity against rat and human ADAMTS-5 was assessed via a fluorescence-based assay. ADAMTS-5 inhibitory activity was confirmed with human aggrecan using an AGC ELISA. The most promising compounds were selected based on reduction of glycosaminoglycan release after interleukin-1 stimulation in mouse cartilage explants and led to the discovery of GLPG1972/S201086. The anticatabolic activity was confirmed in mouse cartilage explants (IC50 < 1.5 μM). The cocrystal structure of GLPG1972/S201086 with human recombinant ADAMTS-5 is discussed. GLPG1972/S201086 has been investigated in a phase 2 clinical study in patients with knee OA (NCT03595618).
The amelioration of cartilage degeneration by ADAMTS-5 Inhibitor delivered in a hyaluronic acid hydrogel
Biomaterials 2014 Mar;35(9):2827-36.PMID:24424207DOI:10.1016/j.biomaterials.2013.12.076.
Degradation of proteoglycan is the key early event in the development of osteoarthritis (OA). The aggrecanase ADAMTS-5 has been identified as the major enzyme responsible for the degradation and thus is an attractive therapeutic target for OA. However, currently there is no report on using an ADAMTS-5 inhibition strategy for OA treatment. The present study aimed to investigate the synergic effect of combining an ADAMTS-5 Inhibitor (114810) with a hyaluronic acid hydrogel (HAX) for OA therapeutics. Two OA models were induced by surgically creating an osteochondral defect or removing the anterior cruciate ligament (ACL) in Sprague-Dawley rats. Human OA cartilage was obtained from total joint replacement patients. Both human and rat OA cartilage showed marked proteoglycan loss with significantly increased ADAMTS-5 expression. The effectiveness of ADAMTS-5 inhibition by 114810 was confirmed by a cartilage explants assay in vitro, which showed that the 114810 halted the aggrecanase-mediated (374)ARGS neoepitope released from aggrecan induced by IL-1β stimulation. The in vivo effect of ADAMTS-5 inhibition was assessed by the articular injection of HAX with 114810 into OA knee joints. Evaluated eight weeks after injection, 114810 with HAX significantly promoted the in vivo cartilage healing in the osteochondral defect model, and prevented the progression of degenerative changes in the ACL model. Our results confirmed that ADAMTS-5 is an effective target for OA treatment, and the intra-articular injection of an ADAMTS-5 Inhibitor within HAX gel could be a promising strategy for OA treatment.
