CP-532623 is a CETP inhibitor and elevates high-density lipoprotein cholesterolion. CP-532623 is a close structural analogue of Torcetrapib. CP-532623 has highly lipophilic properties[1][2][3].
CP-532623 is highly lymphatically transported (28% of dose), and lymphatic transport is closely correlated with drug affinity for ex-vivo lymph lipoproteins or triglyceride emulsions and poorly relates to solubility in mixtures of lipoprotein core and/or surface lipids. CP-532623 alters the kinetics of lymph lipid transport and decreases lymph lipid transport in chylomicrons[2].
CP-532623 (50 mg; oral administration; adult male greyhound dogs) treatment substantially transports into the lymphatic system (>25% dose) in fed and fasted dogs. Food enhances oral bioavailability (from 44 to 58%, respectively) and the proportion of the absorbed dose transports via the lymph (from 61 to 86% and from 68 to 83%, respectively). Lymphatic triglyceride transport is significantly lower in fed dogs administered CP-532623[3]. Animal Model: Adult male greyhound dogs (27-39 kg)[3]

Effects of CP-532,623 and torcetrapib, cholesteryl ester transfer protein inhibitors, on arterial blood pressure
J Cardiovasc Pharmacol 2009 Jun;53(6):507-16.PMID:19455053DOI:10.1097/FJC.0b013e3181a8184c.
ILLUMINATE, the phase 3 morbidity and mortality trial of the cholesteryl ester transfer protein (CETP) inhibitor, torcetrapib, plus atorvastatin terminated in 2006. The underlying morbidity and mortality cause remains undetermined. In addition to lipoprotein changes, off-target increases in blood pressure (BP), sodium, bicarbonate, and aldosterone and potassium decreases were described. We report nonclinical and clinical studies using torcetrapib and a closely related CETP inhibitor, CP-532,623, to further characterize this pharmacology. Pressor effects of torcetrapib and CP-532,623 were observed in monkeys and human subjects. CETP inhibition and high-density lipoprotein cholesterol elevation were demonstrated. In humans, high- versus low-dose CP-532,623 produced significantly greater pressor effects despite similar maximal CETP inhibition. Inhibition of CETP was seen 48 hours post dose, whereas BP elevation dissipated by 24 hours, temporally dissociating CETP inhibition from BP changes. These data, and structural similarities between the compounds, support the conclusion that the BP effects are related to chemotype. We also observed an acute aldosterone increase without changes in renin in monkeys. Continuous BP measurements showed persistent elevations, whereas aldosterone changes were transient, suggesting that increases in BP were not directly the result of renin-angiotensin-aldosterone system activation and may, in part, be due to direct effects on blood vessels or other nongenomic effects.
In vitro-in vivo evaluation of lipid based formulations of the CETP inhibitors CP-529,414 (torcetrapib) and CP-532,623
Eur J Pharm Biopharm 2014 Nov;88(3):973-85.PMID:25152213DOI:10.1016/j.ejpb.2014.08.006.
The present study investigated the use of lipid based drug delivery systems to enhance the oral bioavailability of the CETP inhibitors CP-532,623 and torcetrapib. A series of self-emulsifying lipid based drug delivery systems (SEDDS) were assembled and examined using an in vitro lipid digestion model to evaluate patterns of drug precipitation under simulated intestinal conditions. Drug exposure after oral administration of the same formulations was subsequently assessed in beagle dogs. CP-532,623 was maintained in a solubilised state during dispersion of most formulations in simulated intestinal fluid, however, solubilisation capacity was reduced to various degrees upon in vitro digestion. Administration of SEDDS formulations to beagle dogs resulted in moderate differences in plasma AUC when compared to the differences in solubilisation observed in vitro. Similar trends were observed for torcetrapib. In all cases, however, in vivo exposure of CP-532,623 was greatly enhanced by administration in lipid based drug delivery systems when compared to a powder formulation. Some correlation between in vitro solubilisation and in vivo drug exposure (AUC) was evident; however, this was not linear. The data suggest that for highly lipophilic drugs such as CP-532,623 in vitro digestion data may be a conservative in vitro indicator of utility and that good exposure may be evident even for formulations that result in significant drug precipitation during in vitro digestion.
Correlating in Vitro Solubilization and Supersaturation Profiles with in Vivo Exposure for Lipid Based Formulations of the CETP Inhibitor CP-532,623
Mol Pharm 2017 Dec 4;14(12):4525-4538.PMID:29076741DOI:10.1021/acs.molpharmaceut.7b00660.
Lipid based formulations (LBFs) are a promising formulation strategy for many poorly water-soluble drugs and have been shown previously to enhance the oral exposure of CP-532,623, an oral cholesteryl ester transfer protein inhibitor. In the current study, an in vitro lipid digestion model was used to probe the relationship between drug solubilization and supersaturation on in vitro dispersion and digestion of LBF containing long chain (LC) lipids and drug absorption in vivo. After in vitro digestion of LBF based on LC lipids, the proportion of CP-532,623 maintained in the solubilized state in the aqueous phase of the digest was highest in formulations containing Kolliphor RH 40, and in most cases outperformed equivalent formulations based on MC lipids. Subsequent administration of the LC-LBFs to beagle dogs resulted in reasonable correlation between concentrations of CP-532,623 measured in the aqueous phase of the in vitro digest after 30 min digestion and in vivo exposure (AUC); however, the LC-LBFs required greater in vitro drug solubilization to elicit similar in vivo exposure when compared to previous studies with MC-LBF. Although post digestion solubilization was enhanced in LC-LBF compared to MC-LBF, equilibrium solubility studies of CP-532,623 in the aqueous phase isolated from blank lipid digestion experiments revealed that equilibrium solubility was also higher, and therefore supersaturation lower. A revised correlation based on supersaturation in the digest aqueous phase and drug absorption was therefore generated. A single, linear correlation was evident for both LC- and MC-LBF containing Kolliphor RH 40, but this did not extend to formulations based on other surfactants. The data suggest that solubilization and supersaturation are significant drivers of drug absorption in vivo, and that across formulations with similar formulation composition good correlation is evident between in vitro and in vivo measures. However, across dissimilar formulations, solubilization and supersaturation alone are not sufficient to explain drug exposure and other factors also likely play a role.
The role of the intestinal lymphatics in the absorption of two highly lipophilic cholesterol ester transfer protein inhibitors (CP524,515 and CP532,623)
Pharm Res 2010 May;27(5):878-93.PMID:20221896DOI:10.1007/s11095-010-0083-0.
Purpose: To evaluate the potential role of intestinal lymphatic transport in the absorption and oral bioavailability of members of an emerging class of anti-atherosclerosis drugs (CETP inhibitors). CP524,515 and CP532,623 are structurally related with eLogD(7.4) >5; however, only CP524,515 (and not CP532,623) had sufficient solubility (>50 mg/g) in long-chain triglyceride (LCT) to be considered likely to be lymphatically transported. Methods: CP524,515 and CP532,623 were administered intravenously and orally to fasted or fed lymph-cannulated or non-cannulated dogs. Oral bioavailability and lymphatic transport of drug (and triglyceride) was subsequently quantified. Results: Both CETP inhibitors were substantially transported into the lymphatic system (>25% dose) in fed and fasted dogs. Food enhanced oral bioavailability (from 45 to 83% and 44 to 58% for CP524,515 and CP532,623, respectively) and the proportion of the absorbed dose transported via the lymph (from 61 to 86% and from 68 to 83%, respectively). Lymphatic triglyceride transport was significantly lower in fed dogs administered CP532,623. Conclusion: Intestinal lymphatic transport is the major absorption pathway for CP524,515 and CP532,623, suggesting that a LCT solubility >50 mg/g is not an absolute requirement for lymphatic transport. The effect of CP532,623 on intestinal lipid transport may suggest a role in the activity/toxicity profiles of CETP inhibitors.
The mechanism of lymphatic access of two cholesteryl ester transfer protein inhibitors (CP524,515 and CP532,623) and evaluation of their impact on lymph lipoprotein profiles
Pharm Res 2010 Sep;27(9):1949-64.PMID:20635194DOI:10.1007/s11095-010-0199-2.
Purpose: To explore the mechanism of lymphatic access of the CETP inhibitors (CETPi) CP524,515 and CP532,623 and probe their potential effect on lymph lipoprotein development. Methods: Lymphatic access mechanisms were examined via correlation of lymphatic drug transport profiles with drug affinity for lymph lipoproteins and drug solubility in representative combinations of lipoprotein lipids. The effects of the CETPi on lymph lipoprotein profiles were evaluated by ultracentrifugation and flow cytometry. Results: Both CETPi were highly lymphatically transported (22-28% of dose), and lymphatic transport was closely correlated with drug affinity for ex-vivo lymph lipoproteins or triglyceride emulsions and poorly related to solubility in mixtures of lipoprotein core and/or surface lipids. Both CETPi altered the kinetics of lymph lipid transport and decreased lymph lipid transport in chylomicrons. Conclusion: Lymphatic transport of the CETPi appears to reflect high affinity for the interface of lymph lipoproteins rather than solubilisation in the lipoprotein core and confirms that triglyceride solubilities >50 mg/g are not necessarily a pre-requisite for lymphatic transport. The CETPi also led to changes to lipoprotein processing in the enterocyte including a reduction in lipid transport in chylomicrons. Changes to intestinal lipoprotein profiles may contribute to the changes in systemic lipoprotein levels seen during CETPi therapy.
