[VIRTUAL] Olanzapine/Samidorphan Mitigates Weight Gain across Subgroups of Patients Known to Be at Increased Risk for Weight Gain with Olanzapine Treatment () - Mar 1, 2021 - Abstract #SIRS2021SIRS_174; Relative to olanzapine, the odds ratios (95% CI) for having a ≥10% weight gain from baseline at week 24 with OLZ/SAM treatment were 0.50 (0.31, 0.80) in the overall population, 0.41 (0.23, 0.73) for males, 0.68 (0.30, 1.55) for females, 0.65 (0.25, 1.70) for age <30 years, 0.46 (0.27, 0.78) for age ≥30 years, 0.47 (0.27, 0.82) for black patients, 0.55 (0.24, 1.30) for non-black patients, 0.57 (0.32, 1.00) with BMI <27 kg/m2, and 0.38 (0.16, 0.87) with BMI ≥27 kg/m2. Discussion In this exploratory analysis of the 24-week, phase 3 study of patients with schizophrenia, the combination OLZ/SAM treatment mitigated weight gain associated with olanzapine across several patient subgroups, including groups of patients who are known to be at higher risk for weight gain with olanzapine based on sex, race, age, and baseline BMI.

Clinical, Journal, Combination therapy: Bioequivalence of Olanzapine Given in Combination With Samidorphan as a Bilayer Tablet (ALKS 3831) Compared With Olanzapine-Alone Tablets: Results From a Randomized, Crossover Relative Bioavailability Study. (Pubmed Central) - Jul 31, 2020 Ratios of OLZ AUC , AUC , and C were compared between treatments and tested for bioequivalence, determined by 90%CIs of the geometric mean ratios (GMRs). GMRs of OLZ AUC , AUC , and C were close to 1, and the 90%CIs of the GMRs were contained within the bioequivalence limit of 80%-125% for comparison of ALKS 3831 with B-OLZ, ALKS 3831 with OLZ, and OLZ with B-OLZ, demonstrating bioequivalence of OLZ in ALKS 3831, OLZ, and B-OLZ.

PK/PD data, Journal: Effect of Food on the Pharmacokinetics of a Combination of Olanzapine and Samidorphan. (Pubmed Central) - Jul 31, 2020 Although the lower bound of the 90%CI for the fed/fasted ratio of SAM C (76%-94%) was slightly below the 80% equivalence limit, this slight decrease was not considered clinically meaningful. The results indicated that food does not have a clinically relevant impact on the PK of OLZ and SAM given as OLZ/SAM.

Clinical, PK/PD data, Journal: Combination of Olanzapine and Samidorphan Has No Clinically Significant Effect on the Pharmacokinetics of Lithium or Valproate. (Pubmed Central) - Jun 4, 2020 Consistent with previously reported findings on olanzapine, administration of multiple doses of OLZ/SAM did not have a clinically significant effect on the pharmacokinetics of lithium or valproate. Co-administration of OLZ/SAM and lithium or valproate was generally well tolerated; the safety profile of OLZ/SAM was consistent with that observed in previous clinical studies.

PK/PD data, Journal: Effect of hepatic and renal impairment on the pharmacokinetics of olanzapine and samidorphan given in combination as a bilayer tablet. (Pubmed Central) - Apr 26, 2020 Compared with healthy control subjects, subjects with severe renal impairment had a 33% and 56% reduction in clearance, a 1.51- and 2.31-fold increase in AUC, and a 1.32- and 1.37-fold increase in C of olanzapine and samidorphan, respectively. OLZ/SAM 5/10 mg was generally well tolerated under the conditions of the studies, with a safety profile consistent with that observed in other clinical studies of OLZ/SAM.

Review, Journal: New discoveries for an old drug: A review of recent olanzapine research. (Pubmed Central) - Feb 15, 2020 Olanzapine remains a useful antipsychotic albeit with careful monitoring. Further research is needed to compare the different options available to mitigate olanzapine-induced weight gain and to evaluate potential synergism between pharmacological and non-pharmacological treatments.

A Combination of Olanzapine and Samidorphan has No Clinically Relevant Effect on QT Prolongation up to Supratherapeutic Doses (Floridian Ballroom) - Oct 17, 2019 - Abstract #ACNP2019ACNP_782; Metabolic parameter changes were generally small, similar between groups over 24 weeks, and remained stable over an additional 52 weeks of open-label OLZ/SAM treatment. OLZ/SAM, in doses and plasma concentrations up to supratherapeutic levels, was well tolerated and had no clinically relevant effects on electrocardiogram parameters, including QT interval, in patients with schizophrenia.
