Pooled analysis of routine safety parameters observed in healthy participants at baseline and following placebo administration in early phase clinical studies. Clin Transl Sci 2024; 17:e13715. [PMID: 38266056 PMCID: PMC10777607 DOI: 10.1111/cts.13715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 12/12/2023] [Accepted: 12/14/2023] [Indexed: 01/26/2024] Open
Abstract
Phase I trials inform on the initial safety profile of a new molecule and impact whether further development is pursued or not. Understanding the effect of non-pharmacological factors on the variability of routine safety parameters could improve decision making in these early clinical trials, helping to separate signals related to the new molecule from background "noise." To understand the impact of non-pharmacological factors on routine safety parameters, we evaluated pooled safety data from over 1000 healthy participants treated with placebo in phase I trials between 2009 and 2018. The phase I participants were predominantly men, less than or equal to 50 years, White, and non-Hispanic; and approximately an equal proportion had body mass index in the normal and overweight/obese range. Following administration of placebo, vital signs, electrocardiogram, and laboratory parameters remained near predose baseline values. Large changes from baseline were observed for many safety parameters, but these occurred in a relatively small number of participants. At least one adverse event (AE) occurred in 49.7% of participants receiving placebo in single ascending dose (SAD) studies and in 72.4% of participants receiving placebo in multiple ascending dose (MAD) studies, with headache being the most commonly reported AE (18.7% in SAD and 28.3% in MAD studies). Overall, these analyses are consistent with non-pharmacological factors having a small impact on routine safety parameters in a phase I trial. The provided supplemental data may be used to contextualize the magnitude and frequency of abnormal safety values and AEs observed in phase I trials.

Data driven evaluation of healthy volunteer characteristics at screening for phase I clinical trials to inform on study design and optimize screening processes. Clin Transl Sci 2021; 14:2450-2460. [PMID: 34378856 PMCID: PMC8604224 DOI: 10.1111/cts.13113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Revised: 06/09/2021] [Accepted: 06/21/2021] [Indexed: 11/30/2022] Open
Abstract
Protocols for clinical trials describe inclusion and exclusion criteria based on general and compound-specific considerations to ensure subject safety and data quality. In phase I clinical trials, healthy volunteers (HVs) are screened against these criteria that often specify predefined eligibility ranges for vital signs, electrocardiogram, and laboratory tests. HVs are excluded if baseline parameters deviate from these ranges even though this may not indicate underlying pathology, which could delay trial execution. Data from 3365 HVs participating in 9670 screening visits for 94 phase I HV trials, conducted between December 2008 and May 2019 at the Janssen Clinical Pharmacology Unit, were retrospectively analyzed. Commonly predefined protocol ranges were overlaid with HV data to estimate predicted screen failure rates (SFRs). Of the overall population, 91% was White and 64% were men with mean age of 42.8 ± 12.5 years. High predicted SFRs are related to cardiovascular/metabolic (body mass index, heart rate [HR], blood pressure [BP], and corrected QT Fridericia's formula [QTcF]), renal (estimated glomerular filtration rate [eGFR]), liver (alanine aminotransferase [ALT], and total bilirubin), and coagulation (prothrombin time [PT]) parameters. Predicted SFRs increased with age for high systolic and diastolic BP, QTcF interval, and eGFR. In contrast, lower SFRs in the older age groups were seen for low diastolic BP, liver function test, ALT, PT, and total bilirubin. This analysis can be used to inform on study design, protocol inclusion and exclusion criteria, and to optimize the screening process. Data-driven critical appraisal of proposed inclusion and exclusion criteria using a risk-based approach may significantly reduce screen failure rates without compromising subjects' safety.

Safety of healthy subjects in first-in-human multiple-dose studies: A pooled analysis. Int J Clin Pharmacol Ther 2021; 59:1-7. [PMID: 32990215 PMCID: PMC7737527 DOI: 10.5414/cp203760] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/16/2020] [Indexed: 11/25/2022] Open
Abstract
Purpose: Reflecting the extended scope of the valid EMA regulation, this analysis intends to contribute to the knowledge about risk for participants in first-in-human (FiH) multiple-dose studies. Materials and methods: All FiH multiple-dose studies in healthy subjects performed by the Bayer Department of Clinical Pharmacology, Cardiovascular, between 2006 and 2019 were analyzed. Study reports were reviewed for study designs, demographics, treatment-emergent adverse events (TEAEs), and safety laboratory results above the 1.5-fold of the upper limit of normal (aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine kinase (CK), amylase, lipase, glutamate dehydrogenase (GLDH), gamma glutamyl transpeptidase (GGT), total bilirubin, and creatinine in serum), and data were analyzed. Results: 12 out of 16 studies were included. Indications for development were cardiovascular (7), pulmonary (3), kidney (1), and hematological (1) diseases. 496 healthy male subjects (mean age 33.8 years, mean BMI of 24.7 kg/m2) received treatment (370 active, 126 placebo). 293 subjects had at least 1 TEAE (59.1%): 231 (62.4%) after active treatment and 126 (49.2%) after placebo. Subjects with a maximum TEAE intensity of moderate did not differ between active and placebo. The only severe TEAE was unrelated to the study, the only serious TEAE on active treatment was not considered drug-related. Subjects had a significantly higher relative risk on active treatment versus placebo to experience an overall TEAE. No relevant differences between active and placebo for the analyzed laboratory increases were seen. Conclusion: Subjects were not exposed to an undue risk in the analyzed studies. Adverse events and laboratory value increases occur frequently under placebo treatment. The results can help in the risk stratification for and interpretation of other phase I studies.

Abstract
BACKGROUND This study aims to investigate the incidence of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and triglyceride (TG) elevation, and the relationship with the phase I unit effect, and the moderate activity in healthy subjects enrolled in Phase I clinical trials. METHODS The demographic, AST, ALT, TG and activity data were collected from the placebo (146 subjects) groups and tested drug (885 subjects) groups in 20 phase I trials. RESULTS Elevated AST, ALT and TG levels above the upper limit of normal were detected in 1.37%, 4.79% and 34.7% of subjects in the placebo group, respectively, 3.73%, 6.67% and 39.2% of subjects in the tested drug group, respectively. The incidence of elevated AST, ALT and TG increased with the extended hospital stay. However, the incidence of elevated AST and ALT, but not the elevated TG, was reduced in subjects with moderate exercise during their hospital stay. The logistic regression analysis revealed that the baseline AST and ALT level, female gender, moderate exercise and duration of hospital stay were independent risk factors for ALT elevation. CONCLUSION Moderate exercise during hospital stay may reduce the elevation rate of transaminases, but not TG, in subjects at phase I trials.

[PMID: 30402880 PMCID: PMC6587432 DOI: 10.1002/cpt.1276] [Citation(s) in RCA: 83] [Impact Index Per Article: 13.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2018] [Accepted: 10/19/2018] [Indexed: 12/18/2022]
Abstract
M281 is a fully human, anti-neonatal Fc receptor (FcRn) antibody that inhibits FcRn-mediated immunoglobulin G (IgG) recycling to decrease pathogenic IgG while preserving IgG production. A randomized, double-blind, placebo-controlled, first-in-human study with 50 normal healthy volunteers was designed to probe safety and the physiological maximum for reduction of IgG. Intravenous infusion of single ascending doses up to 60 mg/kg induced dose-dependent serum IgG reductions, which were similar across all IgG subclasses. Multiple weekly doses of 15 or 30 mg/kg achieved mean IgG reductions of ≈85% from baseline and maintained IgG reductions ≥75% from baseline for up to 24 days. M281 was well tolerated, with no serious or severe adverse events (AEs), few moderate AEs, and a low incidence of infection-related AEs similar to placebo treatment. The tolerability and consistency of M281 pharmacokinetics and pharmacodynamics support further evaluation of M281 in diseases mediated by pathogenic IgG.

Abstract
BACKGROUND With the exception of genotoxic oncology drugs, first-in-human, Phase 1 clinical studies of investigational drugs have traditionally been conducted in healthy volunteers (HVs). The primary goal of these studies is to investigate the pharmacokinetics and pharmacodynamics of a novel drug candidate, determine appropriate dosing, and document safety and tolerability. MAIN BODY When tailored to specific study objectives, HV studies are beneficial to manufacturers and patients alike and can be applied to both non-oncology and oncology drug development. Enrollment of HVs not only increases study accrual rates for dose-escalation studies but also alleviates the ethical concern of enrolling patients with disease in a short-term study at subtherapeutic doses when other studies (e.g. Phase 2 or Phase 3 studies) may be more appropriate for the patient. The use of HVs in non-oncology Phase 1 clinical trials is relatively safe but nonetheless poses ethical challenges because of the potential risks to which HVs are exposed. In general, most adverse events associated with non-oncology drugs are mild in severity, and serious adverse events are rare, but examples of severe toxicity have been reported. The use of HVs in the clinical development of oncology drugs is more limited but is nonetheless useful for evaluating clinical pharmacology and establishing an appropriate starting dose for studies in cancer patients. During the development of oncology drugs, clinical pharmacology studies in HVs have been used to assess pharmacokinetics, drug metabolism, food effects, potential drug-drug interactions, effects of hepatic and renal impairment, and other pharmacologic parameters vital for clinical decision-making in oncology. Studies in HVs are also being used to evaluate biosimilars versus established anticancer biologic agents. CONCLUSION A thorough assessment of toxicity and pharmacology throughout the drug development process is critical to ensure the safety of HVs. With the appropriate safeguards, HVs will continue to play an important role in future drug development.
