CLINICAL PHARMACOLOGY and BIOPHARMACEUTICS REVIEW(S) NDA 22561 Clinical Pharmacology Amendment Memo

OCP Review Team: Hristina Dimova, Ph.D., Angela Men, M.D., Ph.D., Mehul Mehta, Ph.D. This review is an amendment of the NDA 22561 review for Mavenclad, (cladribine in DARRTS on March 13, 2019) focusing on a new proposed Post-marketing Requirement (PMR). Background of Metabolism and in-vitro studies results: Cladribine is not a substrate of cytochrome P450 enzymes and does not show significant potential to act as inhibitor of CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1 and CYP3A4. Cladribine has no clinically meaningful inductive effect on CYP1A2, CYP2B6 and CYP3A4 enzymes. Transporter Systems: Cladribine is a substrate of P-glycoprotein (P-gp), breast cancer resistance protein (BCRP), equilibrative nucleoside transporter 1 (ENT1) and concentrative nucleoside transporter 3 (CNT3). New PMR: Conduct a clinical drug-drug interaction (DDI) study to evaluate the effect of cladribine on the pharmacokinetics (PK) of oral contraceptives. Include an evaluation of the effect on the components ethinyl estradiol (EE) and norelgestromin (NGMN). Rationale: No in vivo DDI study has been conducted to evaluate the effect of cladribine on systemically acting hormonal contraceptives. Currently it is unknown whether cladribine may reduce the effectiveness of hormonal contraceptives. Considering the in vitro study results described in Section 3.3.3. -

Each synthesis of these new drug candidates include multi-steps procedures. Overall, discovering a new drug is a very time-consuming and very costly works. The development of molecular modelling programs and their applications in pharmaceutical research have been formalized as a field of study known computer assisted drug design (CADD) or computer assisted molecular design (CAMD). In this study, using the above techniques, Monoamine Oxidase isozymes, which play an essential role in the oxidative deamination of the biogenic amines, were studied. Compounds that inhibit these isozymes were shown to have therapeutic value in a variety of conditions including several psychiatric and neurological as well as neurodegenerative diseases. First, a series of new pyrazoline derivatives were screened using molecular modelling and docking methods and promising lead compounds were selected, and proposed for synthesis as novel selective MAO-A or –B inhibitors. -

Received November 18, 2018; accepted January 25, 2019 β-Adrenoceptors are subclassified into 3 subtypes (β1–β3). Among these, β3-adrenoceptors are present in various types of smooth muscle and are believed to play a role in relaxation responses of these muscles. β3-Adrenoceptors are also present in urinary bladder smooth muscle (UBSM), although their expression varies depending on the animal species. To date, there has been little information available about the endo- genous ligand that stimulates β3-adrenoceptors to produce relaxation responses in UBSM. In this study, to determine whether noradrenaline is a ligand of UBSM β3-adrenoceptors, noradrenaline-induced relaxation was analyzed pharmacologically using rat UBSM. We also assessed whether noradrenaline metabolites were ligands in UBSM. In isolated rat urinary bladder tissues, mRNAs for β1-, β2-, and β3-adrenoceptors were detected using RT-PCR. In UBSM preparations contracted with methacholine (3 105 M), noradrenaline- 6 induced relaxation was not inhibited by the following antagonists: atenolol (10 M; selective β1-adrenoceptor 8 7 antagonist), ICI-118,551 (3 10 M; selective β2-adrenoceptor antagonist), propranolol (10 M; non-selective β-adrenoceptor antagonist), and bupranolol (107 M; non-selective β-adrenoceptor antagonist). -
Discrimination Between Mechanism-Based Inactivation and Tight Binding Inhibitor Behavior

DOI: 10.18097/bmcrm00115 1 EXPERIMENTAL RESEARCH A SIMPLE APPROACH FOR PILOT ANALYSIS OF TIME-DEPENDENT ENZYME INHIBITION: DISCRIMINATION BETWEEN MECHANISM-BASED INACTIVATION AND TIGHT BINDING INHIBITOR BEHAVIOR O.A. Buneeva, L.N. Aksenova, A.E. Medvedev* Institute of Biomedical Chemistry, 10 Pogodinskaya str., Moscow, 119121 Russia; *e-mail: [email protected] The increase in enzyme inhibition developed during prolonged incubation of an enzyme preparation with a chemical substance may be associated with both the non-covalent and also with covalent enzyme-inhibitor complex formation. The latter case involves catalytic conversion of a mechanism-based irreversible inhibitor (a poor substrate) into a reactive species forming covalent adduct(s) with the enzyme and thus irreversibly inactivating the enzyme molecule. Using a simple approach, based on comparison of enzyme inhibition after preincubation with a potential inhibitor at 4ºC or 37ºC we have analyzed inhibition of monoamine oxidase A (MAO A) by known MAO inhibitors pargyline and pirlindole (pyrazidol). MAO A inhibitory activity of pirlindole (reversible tight binding inhibitor of MAO A) assayed after mitochondrial wash was basically the same for the incubation at both 4ºC and 37ºC. In contrast to pirlindole, the effect of pargyline (mechanism based irreversible MAO inhibitor) strongly depended on the temperature of the incubation medium. At 37ºC the residual activity MAO A in the mitochondrial fraction after washing was significantly lower than in the mitochondrial samples incubated with pargyline at 4ºC. Results of this study suggest that using analysis of both time- and temperature-dependence of inhibition it is possible to discriminate mechanism-based irreversible inhibition and reversible tight binding inhibition of target enzym Key words: enzyme inhibition; time-dependent and temperature-dependent inhibition; mechanism-based inhibitors; reversible tight binding inhibitors DOI: 10.18097/BMCRM00115 INTRODUCTION (England). -

Higher concentrations of CEC (up to 100 gM) or longer treatment periods (upto 40 min) were no more effective. 3 Adrenoceptor agonists and antagonists competitively inhibited [1251]-HEAT binding with Hill coefficients close to unity indicating a single a1-adrenoceptor subtype is present. The affinity (Ki) of subtype selective agonists (oxymetazoline, SDZ NVI-085) and antagonists (5-methylurapidil, WB4101, benoxathian, phentolamine) was consistent with binding to an xB-adrenoceptor subtype. 4 The (-)- and (+)-enantiomers of niguldipine had an equal and low affinity for a,-adrenoceptor binding sites both in untreated (log K -6.66 and -6.90 respectively) and CEC-treated membranes in which -70% of sites had been inactivated (log Ki-6.41 and -6.86 respectively). -
Sympathoadrenergic Modulation of Hematopoiesis: a Review of Available Evidence and of Therapeutic Perspectives

M. Maestroni Center for Research in Medical Pharmacology, University of Insubria, Varese, Italy Innervation of the bone marrow (BM) has been described more than one century ago, however the first in vivo evidence that sympathoadrenergic fibers have a role in hematopoiesis dates back to less than 25 years ago. Evidence has since increased showing that adrenergic nerves in the BM release noradrenaline and possibly also dopamine, which act on adrenoceptors and dopaminergic receptors (DR) expressed on hematopoietic cells and affect cell survival, proliferation, migration and engraftment ability. Remarkably, dysregulation of adrenergic fibers to the BM is associated with hematopoietic disturbances and myeloproliferative disease. Several adrenergic and dopaminergic agents are already in clinical use for non-hematological indications and with a usually favorable risk-benefit profile, and are therefore potential candidates for Edited by: non-conventional modulation of hematopoiesis.
