Biricodar (VX-710) is a modulator of P-glycoprotein and MRP-1; shows effective chemosensitizing activity in multidrug resistant cells.
Biricodar shows activity against both P-glycoprotein (Pgp) and MRP-1 and also has activity in increasing drug uptake and retention and reversing drug resistance mediated by wild-type BCRP (BCRPR482). In 8226/Dox6 cells (Pgp), biricodar increases mitoxantrone and daunorubicin uptake by 55 and 100%, respectively, increases their retention by 100 and 60%, respectively, and increases their cytotoxicity 3.1- and 6.9-fold, respectively. Biricodar also increases the uptake, retention and cytotoxicity in HL60/Adr (MRP-1) and 8226/MR20 cells (BCRP(R482)), but has little effect in MCF7 AdVP3000 cells (BCRP(R482T))[1]. VX-710 is a non-macrocyclic pipecolinate derivative which binds the FK506 receptor protein. VX-710 has been shown to restore sensitivity in a range of multidrug-resistant cells, including myeloma, melanoma, carcinoma and leukaemia[2]. Biricodar effectively inhibits photoaffinity labeling of P-glycoprotein by [3H]azidopine or [125I]iodoaryl azido-prazosin with EC50 values of 0.75 and 0.55 μM[3].

VX-710 (Biricodar) increases drug retention and enhances chemosensitivity in resistant cells overexpressing P-glycoprotein, multidrug resistance protein, and breast cancer resistance protein
Clin Cancer Res 2004 Mar 1;10(5):1826-34.PMID:15014037DOI:10.1158/1078-0432.ccr-0914-3.
Purpose: The pipecolinate derivative VX-710 (Biricodar; Incel) is a clinically applicable modulator of P-glycoprotein (Pgp) and multidrug resistance protein (MRP-1); we studied its activity against the third multidrug resistance (MDR)-associated drug efflux protein, breast cancer resistance protein (BCRP). Experimental design: VX-710 modulation of uptake, retention, and cytotoxicity of mitoxantrone, daunorubicin, doxorubicin, topotecan, and SN38 was studied in cell lines overexpressing Pgp, MRP-1 and wild-type (BCRP(R482)) and mutant (BCRP(R482T)) BCRP. Results: In 8226/Dox6 cells (Pgp), VX-710 increased mitoxantrone and daunorubicin uptake by 55 and 100%, respectively, increased their retention by 100 and 60%, respectively, and increased their cytotoxicity 3.1- and 6.9-fold, respectively. In HL60/Adr cells (MRP-1), VX-710 increased mitoxantrone and daunorubicin uptake by 43 and 130%, increased their retention by 90 and 60%, and increased their cytotoxicity 2.4- and 3.3-fold. In 8226/MR20 cells (BCRP(R482)), VX-710 increased mitoxantrone uptake and retention by 60 and 40%, respectively, and increased cytotoxicity 2.4-fold. VX-710 increased daunorubicin uptake and retention by only 10% in 8226/MR20 cells, consistent with the fact that daunorubicin is not a substrate for BCRP(R482), but, nevertheless, it increased daunorubicin cytotoxicity 3.6-fold, and this increase was not associated with intracellular drug redistribution. VX-710 had little effect on uptake, retention, or cytotoxicity of mitoxantrone, daunorubicin, doxorubicin, topotecan, or SN38 in MCF7 AdVP3000 cells (BCRP(R482T)). Conclusions: VX-710 modulates Pgp, MRP-1, and BCRP(R482), and has potential as a clinical broad-spectrum MDR modulator in malignancies such as the acute leukemias in which these proteins are expressed.
Biricodar (VX-710; Incel): an effective chemosensitizer in neuroblastoma
Br J Cancer 1999 Jun;80(8):1190-6.PMID:10376971DOI:10.1038/sj.bjc.6990485.
Clinical studies have suggested that both MDR1 and MRP may play a significant role in the chemosensitivity and outcome of neuroblastoma. To clarify the nature of multidrug resistance (MDR) in this tumour a series of six neuroblastoma cell lines have been characterized with regard to P-glycoprotein, MRP and LRP expression using immunocytochemistry and expression of MDR1, MRP, LRP and topoisomerase II genes using reverse transcription polymerase chain reaction (RT-PCR). By RT-PCR, all lines expressed MRP, five expressed LRP and four expressed MDR1, but protein levels of each of these were variable. Chemosensitization to a range of MDR-associated drugs (vincristine, doxorubicin, etoposide, taxotere, topotecan) and non-MDR-associated drugs (cisplatin, melphalan) by three modulating agents, cyclosporin A, PSC 833 and the novel Biricodar (VX-710; Incel), was evaluated using a colourimetric cytotoxicity assay (MTS). Alteration of daunorubicin efflux by these agents was evaluated using FACS analysis. Clonogenic assay was used to study the influence of these chemosensitizers on vincristine cytotoxicity. Marked sensitization to vincristine was observed in MDR1-positive lines, and a similar but less consistent effect was seen with taxotere, doxorubicin and etoposide. With MRP-positive, MDR-negative lines, only VX-710 caused consistent sensitization. These data confirm MDR1 and MRP expression as contributory factors in chemoresistance in neuroblastoma and indicate that VX-710 may be a useful modulator of both mechanisms and worthy of clinical evaluation in this tumour.
Inhibition of antibiotic efflux in bacteria by the novel multidrug resistance inhibitors Biricodar (VX-710) and timcodar (VX-853)
Antimicrob Agents Chemother 2004 Nov;48(11):4171-6.PMID:15504837DOI:10.1128/AAC.48.11.4171-4176.2004.
Inhibitors of mammalian multidrug efflux, such as the plant alkaloid reserpine, are also active in potentiating antibiotic activity by inhibiting bacterial efflux. Based on this precedent, two novel mammalian multiple drug resistance inhibitors, Biricodar (VX-710) and timcodar (VX-853), were evaluated for activity in a variety of bacteria. Both VX-710 and VX-853 potentiated the activity of ethidium bromide (EtBr), a model efflux substrate, against three clinically significant gram-positive pathogens: Staphylococcus aureus, Enterococcus faecalis, and Streptococcus pneumoniae. Similar to reserpine, VX-710 and VX-853 directly blocked EtBr efflux in S. aureus. Furthermore, these compounds were effective in lowering the MICs of several clinically used antibiotics, including fluoroquinolones, suggesting that VX-710 and VX-853 are representatives of a new class of bacterial efflux inhibitors with the potential for use in combination therapy.
Safety and efficacy of the MDR inhibitor Incel (Biricodar, VX-710) in combination with mitoxantrone and prednisone in hormone-refractory prostate cancer
Cancer Chemother Pharmacol 2003 Apr;51(4):297-305.PMID:12721757DOI:10.1007/s00280-003-0573-4.
Purpose: VX-710 (Biricodar, Incel) restores drug sensitivity to cells expressing P-glycoprotein (P-gp) and multidrug resistance-associated protein (MRP1). MRP1 is expressed in a high proportion of prostate tumors while P-gp expression is variable. Since mitoxantrone (M) and prednisone (P) are substrates for MDR transporters, we initiated a study to evaluate the safety, pharmacokinetics, and efficacy of VX-710 plus M/P in patients with hormone-refractory prostate cancer (HRPC). Patients and methods: Eligible patients had progressive HRPC (defined as new lesions, new disease-related pain, or 50% increase in PSA within 6 weeks of entry), testosterone <30 ng/ml, no prior chemotherapy, ECOG performance status of 0-3, and adequate organ function. Patients received VX-710 (120 mg/m(2) per h) as a 72-h continuous intravenous infusion with intravenous bolus mitoxantrone (12 mg/m(2)) administered 4 h after VX-710 was started and prednisone (5 mg twice daily) administered throughout the study treatment. Endpoints included serum PSA response, PSA response duration, time to PSA progression, pain reduction, and quality of life measures. Results: Enrolled in the study were 40 patients and 184 courses of VX-710 plus M/P were administered. Intensive pharmacokinetics, which were performed on six patients who received one cycle of M/P alone, followed by VX-710 plus M/P for all other cycles, showed that VX-710 did not alter mitoxantrone clearance. VX-710 blood concentration at the time of mitoxantrone administration averaged 4.52 microg/ml. VX-710 plus M/P was well tolerated. Transient nausea/vomiting and mild neutropenia were the principal treatment toxicities. Five patients experienced an uncomplicated febrile neutropenic episode (12%), three had severe nausea/vomiting, and two experienced transient moderate to severe ataxia. Of the 40 patients, 12 (30%, 95% confidence interval 16-44%) had a reduction in PSA of >/=50% and 9 of the 12 patients (23% overall, 95% CI 10-35%) achieved a reduction in PSA of >/=80% that was sustained for the duration of treatment with M/P plus VX-710. The median time to PSA progression was 41 weeks (95% CI 34-68 weeks). Of the 40 patients, 15 completed treatment with stable disease and 13 had progressive disease with increasing serum PSA during study treatment. Median survival was 48 weeks for the intent-to-treat population of 40 patients. Conclusions: The addition of VX-710 to M/P therapy did not appear to increase the proportion of patients with significant serum PSA reductions compared to M/P alone. However, the duration of PSA response observed for the 12 PSA responders suggests that MDR inhibition may benefit some patients with HRPC. In addition to MRP1 or P-gp expression, other mechanisms of drug resistance are probably associated with the relative insensitivity of HRPC to cytotoxic therapy.
A phase II study of the MDR inhibitor Biricodar (INCEL, VX-710) and paclitaxel in women with advanced ovarian cancer refractory to paclitaxel therapy
Gynecol Oncol 2002 Sep;86(3):302-10.PMID:12217752DOI:10.1006/gyno.2002.6762.
Purpose: Incel (Biricodar, VX-710) restores drug sensitivity to P-glycoprotein (MDR1) and multidrug-resistance-associated protein (MRP1) expressing cells. This phase II study evaluated the safety/tolerability, pharmacokinetics, and efficacy of VX-710 plus paclitaxel in women with advanced ovarian cancer refractory to prior paclitaxel therapy. Experimental design: Eligible patients had paclitaxel-refractory disease defined as progressive disease after a minimum of two cycles of paclitaxel (weekly or 3-week schedule) or relapsed disease within 4 months of prior paclitaxel therapy. Patients received 80 mg/m(2) paclitaxel over 3 h starting 4 h after initiation of a 24-h continuous intravenous infusion of 120 mg/m(2)/h VX-710. Cycles were repeated every 3 weeks. Results: Fifty patients received treatment and 45 were evaluable for response. VX-710 + paclitaxel therapy was generally well tolerated. Myelosuppression was the principal toxicity, with a median Cycle 1 nadir absolute neutrophil count of 0.27 x 10(9) cells/L and a 47% overall incidence of Grade 4 neutropenia. Mild to moderate peripheral neuritis or neuropathy was the primary nonhematologic toxicity, affecting 62% of patients. Other nonhematologic toxicities were generally mild to moderate and reversible. Paclitaxel area under the concentration-versus-time curve (AUC) (16 +/- 5.3 microg x h/mL) during the first treatment cycle was comparable to standard 175 mg/m(2) paclitaxel administered over 3 h. Of the 3 patients who achieved partial responses, 2 had progressed during prior paclitaxel therapy. Twelve patients maintained stable disease and 14/45 (31%) of patients had CA-125 reductions of 50-90% for up to 24 weeks. The median time-to-disease progression was 10 weeks for the intent-to-treat population and 20.7 weeks for the CA-125 responders. Conclusions: The results suggest that VX-710 with paclitaxel has modest activity in paclitaxel-resistant ovarian cancer. Further research is warranted in less heavily treated patients.
