Sponsor monitoring in clinical research refers to the oversight and supervision conducted by the sponsor or sponsor's representative throughout the course of a clinical trial. The purpose of sponsor monitoring is to ensure the rights, safety, and well-being of study participants, as well as the quality and integrity of the trial data. Here are some key aspects and considerations related to sponsor monitoring in clinical research
Difference between Monitoring and AuditingClinosolIndia
Monitoring
On-going process usually directed by management to ensure processes are working as intended.
Auditing
A formal, systematic, and disciplined approach designed to evaluate and improve the effectiveness of processes and related controls.
Assures quality of trails.
Auditing is governed by professional standards, completed by individuals independent of the process being audited, and normally performed by individuals with one of several acknowledged certifications.
Objectivity in governance reporting is the benefit of independence
Audit and Inspection in Clinical ResearchClinosolIndia
Audit and inspection are two critical components of quality assurance in the pharmaceutical industry. Both are essential for ensuring compliance with regulatory requirements and for identifying areas where improvements can be made in quality systems.
An audit is a systematic and independent examination of a company's quality system to determine whether it meets the requirements of applicable regulations and standards. The audit process involves reviewing documentation, procedures, and practices to identify potential areas of non-compliance and areas for improvement. The audit can be internal, where a company audits its own quality system, or external, where an independent third-party audits the quality system.
Inspection, on the other hand, is a regulatory process conducted by government authorities to ensure that a company's quality system is compliant with regulations and standards. The inspection process involves a review of a company's facilities, procedures, and documentation to determine whether they meet regulatory requirements. Inspections may be conducted on a routine basis or may be triggered by specific events, such as a product recall or a serious adverse event.
During an audit or inspection, the auditors or inspectors will typically review a range of documents and processes, including:
Standard operating procedures (SOPs) for quality control and quality assurance
Documentation of manufacturing processes and quality control testing
Personnel training records and qualifications
Equipment and facility maintenance and cleaning records
Complaint and deviation handling procedures
Batch records and release testing
The goal of an audit or inspection is to identify any deficiencies in the quality system that could impact product quality or patient safety. Depending on the severity of any non-compliance identified, regulatory action may be taken, such as issuing a warning letter or suspending a company's manufacturing license.
Overall, audits and inspections play a critical role in ensuring the safety, efficacy, and quality of pharmaceutical products, and are an essential part of the regulatory process for the pharmaceutical industry.

Risk Based Monitoring in Clinical trials_Aishwarya Janjale.pptxClinosolIndia
Risk-Based Monitoring (RBM) in clinical trials represents a departure from traditional, one-size-fits-all monitoring approaches. This innovative strategy tailors monitoring activities to the specific risks associated with a trial, optimizing resource utilization and enhancing data quality. This article explores the key principles, benefits, and challenges of RBM, illustrating its transformative impact on the landscape of clinical trial oversight.
Key Principles:
Risk Identification and Assessment:
RBM begins with a comprehensive assessment of potential risks to data integrity, patient safety, and study endpoints. These risks are identified based on factors such as study complexity, patient population, and investigational product characteristics.
Current Trends in Clinical Trial Design and Execution ClinosolIndia
Adaptive Trial Designs: Adaptive trials allow for modifications to key aspects of a trial while it is ongoing, such as sample size, treatment arms, or endpoints. This flexibility can help optimize resources, reduce costs, and improve the efficiency of clinical trials.
Real-world Evidence (RWE): There is an increasing interest in incorporating real-world data and evidence into clinical trial design. RWE involves the use of data collected outside of traditional clinical trials, such as electronic health records, patient registries, and claims databases, to generate insights on treatment effectiveness, safety, and patient outcomes.
Patient-Centric Trials: There is a growing emphasis on patient-centricity in clinical trial design. This includes involving patients in trial planning, considering patient preferences, and incorporating patient-reported outcomes as endpoints. Patient-centric trials aim to improve patient recruitment, retention, and overall trial experience.
Virtual and Decentralized Trials: The COVID-19 pandemic has accelerated the adoption of virtual and decentralized trial approaches. These trials leverage digital technologies, remote monitoring, telemedicine, and home-based visits to reduce the need for frequent site visits and increase patient accessibility, particularly for those who may face geographical or mobility barriers.
Precision Medicine and Biomarker-Based Trials: Advances in genomics and molecular biology have led to an increased focus on precision medicine and biomarker-based trials. These trials aim to identify patient subgroups that are more likely to respond to specific treatments based on their genetic or biomarker profiles, allowing for more targeted and personalized approaches to therapy.
Data Analytics and Artificial Intelligence (AI): The use of data analytics and AI in clinical trial design and execution is gaining momentum. These technologies can help identify patterns, predict outcomes, optimize trial protocols, and streamline data collection and analysis processes, leading to more efficient and informed decision-making.
Collaborative and Platform Trials: Collaborative and platform trials involve partnerships between multiple stakeholders, including academia, industry, patient advocacy groups, and regulatory agencies. These trials aim to streamline trial operations, facilitate data sharing, and enable a more efficient evaluation of multiple interventions or treatment combinations simultaneously.
Risk-Based Monitoring: Traditional on-site monitoring of all trial sites can be resource-intensive. Risk-based monitoring focuses resources on higher-risk areas and uses a combination of centralized monitoring, statistical algorithms, and targeted on-site visits to ensure data quality and patient safety while optimizing resource utilization.
Regulatory Innovations: Regulatory agencies are increasingly exploring innovative approaches to support more efficient and accelerated clinical trials.
Risk Based Monitoring in Clinical Trials.ClinosolIndia
Risk-based monitoring (RBM) is a monitoring strategy in clinical trials that aims to improve the quality and efficiency of data collection while reducing costs and burden on study participants. Rather than conducting monitoring activities at fixed intervals, RBM utilizes a risk assessment approach to identify areas of the study that are at higher risk of errors or deviations from the protocol and focuses monitoring efforts on those areas.
The RBM process begins with a risk assessment, which involves identifying potential risks to the study's data integrity, participant safety, and study conduct. This may include risks related to patient enrollment, data collection, adverse event reporting, or protocol compliance. Based on the risk assessment, the study team creates a risk management plan that outlines the monitoring strategy to be employed throughout the trial.
In RBM, monitoring activities are targeted to focus on the areas of the study that present the highest risk. For example, if a study has a high risk of data entry errors, the monitoring plan may include a more intensive review of data entry activities or require that data be entered in real-time, so errors can be identified and corrected more quickly.
RBM can be facilitated through several tools, such as centralized monitoring, key risk indicator (KRI) dashboards, or data analytics. Centralized monitoring allows for remote review of study data by a team of experts who can identify trends and issues more efficiently. KRIs are pre-defined metrics used to track performance and detect areas of concern, allowing for proactive management of risks. Data analytics can identify unusual patterns or outliers in the data, enabling the study team to focus on those areas of concern.
RBM is a dynamic process that involves ongoing evaluation of the study's risk profile and adjusting the monitoring strategy accordingly. By focusing monitoring efforts on the areas of the study that pose the highest risk, RBM can improve data quality and participant safety, while reducing monitoring costs and burden.

Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.

With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
2. “FIRST, WHAT IS
MONITORING
EXACTLY”?? :)
Clinical monitoring is the oversight and administrative efforts that monitor a participant's health
and efficacy of the treatment during a clinical trial.
3. EXTENT AND NATURE OF
MONITORING:-
The sponsor should ensure that the trials are adequately
monitored. The sponsor should determine the appropriate
extent and nature of monitoring. The determination of the
extent and nature of monitoring should be based on
considerations such as the objective, purpose, design,
complexity, blinding, size, an endpoints of the trial.
4.
5. DURATION,CONDUCT
MONITORING:-
In general there is a need for on-site monitoring, before,
during, and after the trial; however in exceptional
circumstances the sponsor determine that central monitoring
in conjunction with investigators’ training and meetings, and
extensive written guidance can assure appropriate conduct of
the trial in accordance with GCP.
6.
7.
8. Identify Critical Data and
Processes to be Monitored
Sponsors should prospectively identify critical data and processes
that if inaccurate, not performed, or performed incorrectly, would
threaten the protection of human subjects or the integrity of the study
results.
As examples, the following types of data and processes should
ordinarily be identified as critical:
• Verification that informed consent was obtained appropriately
9. Adherence to protocol eligibility criteria designed to exclude
individuals for whom the investigational product may be less safe than
the protocol intended and to include only subjects from the targeted
study population for whom the test article is most appropriate •
Procedures for documenting appropriate accountability and
administration of the investigational product (e.g., ensuring the
integrity of randomization at the site level, where appropriate) •
10.
11. FACTORS TO CONSIDER WHEN DEVELOPING A MONITORING PLAN :-
A monitoring plan ordinarily should focus on
preventing or mitigating important and likely risks,
identified by the risk assessment, to critical data and
processes.
The types (e.g., on-site, centralized), frequency (e.g., early, for
initial assessment and training versus throughout the
study), and extent (comprehensive (100% data verification)
versus targeted or random review of certain data (less than
100% data verification) of monitoring activities will depend to
some degree on a range of factors, considered during the
12.
13. 1) Complexity of the study design :-
More intensive monitoring (e.g., increased frequency and
extent of review) may be necessary as study design
complexity increases. Examples may include studies with
adaptive designs, stratified designs or complex dose
titrations
2) Types of study endpoints -
Endpoints that are more interpretative or subjective
may require on-site visits to assess the totality of
subject records and to review application of protocol
14. More objective endpoints (e.g., death, hospitalization, or clinical
laboratory values and standard measurements) may be more
suitable for remote verification.
Endpoints for which inappropriate subject withdrawal or lack
of follow-up may impede study evaluation are likely to need
more intensive monitoring to identify the reason(s) subjects
are withdrawing and to determine whether follow-up can be
improved.
3) Clinical complexity of the study population - A study that involves a
population that is seriously ill or vulnerable may require more
intensive monitoring and consideration of on-site monitoring
visits to be sure appropriate protection is being provided.
15. Relative experience of the CI and of the sponsor with
the CI
CIs who lack significant experience in conducting and overseeing
investigations, using a novel or innovative medical device, or with the
surgical procedure associated with medical device use may benefit
from more intensive monitoring and frequent communication to
ensure CI understanding of responsibilities.
In addition, the relative experience of a sponsor with the CI may be a
factor in determining an appropriate monitoring plan.
16. Aspects of monitoring:-
1) Failure to follow investigation protocol (the procedures and
treatment subjects must undergo,
as well as the schedule of assessments)
1) Failure to keep adequate and accurate records
2) Problems with the informed consent form
3) Failure to report adverse events
4) Failure to account for the disposition of study drugs
17. Factors that determine the strategy of
monitoring:-
1)BACKGROUND :-it is a critical element of the planning process which enables
stakeholders to get feedback about performance and monitors strategy
implementation.
2) Research Methodology :-The study involves the case study research design
because it develops analytic and problem solving skills allows for exploration of
solutions for complex issues and allows the researcher to apply new knowledge and
skills
18. Monitoring plan :-
For each clinical trial, the sponsor should develop a monitoring plan that
describes the monitoring methods, responsibilities, and requirements for
the trial.
The monitoring plan should include a brief description of the study, its
objectives, and the critical data and study procedures, with particular
attention to data and procedures that are unusual in relation to
clinical routine and require training of study site staff.
The plan should also communicate the specific risks to be addressed
by monitoring and should provide those involved in monitoring with
adequate information to effectively carry out their duties.
19.
20. The components of a monitoring plan might
include the following :-
1. Description of Monitoring Approaches - A description of each
monitoring method to be employed during the study and how it will
be used to address important risks and ensure the validity of critical
data.
2. Communication of Monitoring Results • Format, content, timing, and
archiving requirements for reports and other documentation of
monitoring activities
3. Management of Noncompliance
4. Ensuring Quality Monitoring
5. Monitoring Plan Amendments
21. DOCUMENTING MONITORING ACTIVITIES:-
Documentation of monitoring activities should generally include the
following :
• The date of the activity and the individual(s) conducting and
participating in it
• A summary of the data or activities reviewed
• A description of any noncompliance, potential noncompliance, data
irregularities, or other deficiencies identified
• A description of any actions taken, to be taken, or recommended,
including the person responsible for completing actions and the
anticipated date of completion
