Tuberculosis is a chronic infectious disease, usually localized in the respiratory system and representing one of the most important global social and biomedical health problems associated with the spread of therapy-resistant forms (multidrug-resistant and extensively drug-resistant tuberculosis). One of the most promising targets for the development of antimycobacterial drugs is the enzyme DprE1, which is involved in the synthesis of the cell wall of mycobacteria. In the series of DprE1 inhibitor drugs, the most advanced drug is PBTZ169 (INN maсozinone). Clinical trials (CT) of the efficacy and safety of macozinone are conducted by the pharmaceutical company LLC NEARMEDIC PLUS in the Russian Federation, and in other countries (Sponsors: Innovative Medicines for Tuberculosis Foundation, cole polytechnique fdrale de Lausanne and Bill and Melinda Gates Foundation). The publication describes results of completed I, IIa and Ib phases CT, conducted in the Russian Federation. Aim. The goal of phase I CT was to assess the safety, tolerability and pharmacokinetics (PK) of PBTZ169, 40 mg capsule, after single and multiple administration under fasting conditions in increasing doses in healthy volunteers. The goal of phase IIa CT was to study the efficacy (in terms of early bactericidal activity EBA), safety and PK of the drug PBTZ169, 80 mg capsules, in various doses, when used as monotherapy in patients with newly diagnosed respiratory tuberculosis with bacterial excretion and retained sensitivity to isoniazid and rifampicin. The purpose of phase Ib CT was to evaluate the safety, tolerability, PK of PBTZ169, 80 mg capsule, after single, double and multiple administration under fasting conditions in increasing doses, as well as the effect of food on its bioavailability in healthy volunteers. Materials and methods. The data of 100 healthy volunteers and 15 patients with newly diagnosed pulmonary tuberculosis, who received the study medication PBTZ169, capsules 40 mg and 80 mg, in the dose range 40 mg 1280 mg of PBTZ169, obtained during phase I, IIa and Ib CTs were analyzed. During I phases CTs, safety, tolerability, and PK of the drug after a single and multiple administration under fasting condition and after meals at rising doses were evaluated. The safety assessment included evaluation of AE/SAE, vital signs, ECG results, and laboratory tests results in the safety population. In the course of phase IIa CT, in addition to safety, tolerance, and PK evaluation, the efficacy of the drug (in terms of EBA) using sputum culture on agar with CFU/ml counting (main method) and quantitative PCR method (auxiliary method) was evaluated. Results. During all CTs, a high safety and tolerability profile was shown, the main PK parameters of the drug and the efficacy were described. PBTZ169 demonstrated linear PK in the dosage range up to 640 mg after single and multiple administration, a statistically significant of EBA of the drug after monotherapy at the dose of 640 mg/day was demonstrate, and it was concluded that the preferred regimen of the drug PBTZ169 intake is administration after meals. Good tolerability and a favorable safety profile of the drug in the studied doses range were demonstrate during all the CTs. Conclusion. One of the most promising and currently studied drugs-inhibitors of DprE1, a new target for the cell wall of mycobacteria, is PBTZ169 or macozinone, which is being develop by the Russian pharmaceutical company NEARMEDIC PLUS ltd.

Other than the financial motivations for enrolling in Phase I trials, research on how healthy volunteers perceive the benefits of their trial participation is scant. Using qualitative interviews conducted with 178 U.S. healthy volunteers enrolled in Phase I trials, we investigated how participants described the benefits of their study involvement, including, but not limited to, the financial compensation, and we analyzed how these perceptions varied based on participants’ sociodemographic characteristics and clinical trial history. We found that participants detailed economic, societal, and noneconomic personal benefits. We also found differences in participants’ perceived benefits based on gender, age, ethnicity, educational attainment, employment status, and number of clinical trials completed. Our study indicates that many healthy volunteers believe they gain more than just the financial compensation when they accept the risks of Phase I participation.

Epidemiological Situation

High pathogenicity of anthrax agent combined with unique insensitivity of its spore forms to environmental stresses class it among extremely dangerous biological agents. Registered and effectively used anthrax vaccines made invaluable contribution to the improvement of epidemiological situation around the world. Nevertheless, neglect of non-specific prophylaxis may result in dramatic scenarios and require large-scale measures on rectification of the consequences. Efforts on the development of next-generation vaccines are aimed at safety build-up, decrease in frequency of administration, and enhancement of manufacturing technologies. The review contains the key information on licensed anthrax vaccines designed for medical use, both in the territory of the Russian Federation and abroad. Among multiple experimental developments emphasized have been preparations manufactured by various biopharmaceutical companies in compliance with GMP standards, at different phases of clinical trials in 2016.

Since the beginning of the COVID-19 pandemic, there has been a strong drive and desire to find effective treatments for and protection against the disease. On the webpage ClinicalTrials.gov, a total of 6505 clinical trials currently (September 2021) investigating various aspects of COVID-19 are registered. Of these, 124 studies involving peptides were identified. These 124 were further evaluated, and 88 trials that used peptides only for routine diagnostics were excluded. The remaining 36 trials were classified into 5 different classes according to their function: immunomodulatory (5 trials), regain homeostasis (10 trials), diagnostics/biomarkers (8 trials), vaccination (9 trials), and antiviral activity (4 trials, all overlap with immunomodulatory activities). In the current review, these 36 trials are briefly described and tabularly summarised. According to the estimated finish date, 14 trials have not yet finished. All of the finished trials are yet to report their results. Seven trials were based in the USA, and Egypt, France, the UK, Turkey, and the Russian Federation conducted three trials each. This review aims to present a snapshot of the current situation of peptides in COVID-19 clinical trials and provides a template to follow up on trials of interest; it does not claim to be a complete overview.

The phase I trial is the first step in administering a drug to humans, but it has no therapeutic purpose. Under the absence of therapeutic purpose, healthy volunteers demonstrated different motivations, unlike the actual patients participating in trials. There were many reported motivations, such as financial motivation, contributing to the health science, accessing ancillary health care benefits, scientific interest or interest in the goals of the study, meeting people, and general curiosity. The aim of this study was to identify the motivation and characteristics of healthy volunteers participating in phase I trials in the Republic of Korea. We gave surveys to 121 healthy volunteers to study their demographic characteristics and the reasons of participation. We identified whether the decision to participate in the research was influenced by demographic factors and whether the perception and attitudes toward the research were influenced by the characteristics of the healthy volunteers. After completion of the first survey, 12 healthy volunteers who had participated in a phase I clinical trial were selected to answer the second interview. According to our survey, most healthy volunteers were unmarried men and economically dependent. Most of them participated in the study because of financial reward. The most important factor to measure financial reward was the research period. Also, 43% of the volunteers were university students, 42% answered “university graduation” and 55% were residing in family-owned houses. Many healthy volunteers were found to be living in family homes and to have a student status or lack of economic independence. Results of the survey showed that 64% of respondents indicated having more than one clinical trial participation. In-depth interviews showed that healthy volunteers had diverse motivation to participate in research and that healthy volunteer perceive the clinical trial positively. The main motivation for healthy volunteers’ participation in research was “financial reward.” Healthy volunteers also considered research schedules, processes, and safety, and had a positive perception of clinical trials, but they thought that the public has a negative perception.

Despite similar financial goals among healthy volunteers, there are regional differences in the culture of Phase I participation. Chapter 3 focuses on this theme to further unpack variations in how patterns of imbricated stigma influence healthy volunteers’ perceptions of Phase I trials, particularly with respect to the longevity of their study involvement. Specifically, East Coast participants tend to be well-networked as part of their long-term, active pursuit of clinical trials, but they often also express anti-capitalist critiques of the industry. In comparison, Midwesterners tend to be more passive about their trial participation, thinking of it as a short-term financial opportunity to counterbalance a temporary setback. West Coast participants occupy a hybrid culture between those of the East Coast and Midwest participants, actively seeking out new studies but expressing a distrust in the clinics and wanting to limit their study involvement. These regional cultures act as a prism for healthy volunteers’ perceptions of Phase I trials, shaping whether and how they adopt identities as research participants.

Aims/Background A fundamental part of all clinical trials is informed consent, reflecting the respect for the volunteer’s autonomy. Research participation is voluntary; therefore, certain aspects of the proposed study must be disclosed so that volunteers can make an informed decision. In this study, we aimed to examine the level of comprehension and recall of healthy volunteers from the informed consent process. Methods The study was carried out at a single phase I clinical trials unit. A questionnaire was administered to each volunteer to assess recall of important aspects of the study at the day-1 visit following the informed consent process. The questionnaire contained seven questions regarding study objectives, route, frequency and type of drug administration, adverse effects, number of subjects previously exposed and remuneration. One point was awarded for each correct answer. Results A total of 266 volunteers were administered the questionnaire. The mean total score (±standard deviation) for all volunteers was 4.5 ± 1.1 points out of 7, with a range of 0.8–6.7. For all 10 studies, 91% of volunteers responded correctly when answering about the route of administration, and 90% were able to accurately state the correct payment amount. Only 7% were able to repeat the aims of the study correctly. Conclusion The poor performance of our study volunteers raises concerns about recall of information prior to study drug administration. This has implications for the volunteer’s safety and ability to provide true informed consent. Interventions to improve recall prior to dosing should be undertaken.
