The Importance of Clinical Trial Feedback in Drug Discovery


Clinical trials have long struggled with participant recruitment and retention. Although there are several factors influencing recruitment and retention, some of the issues may be related to the fact that trial design and delivery are not sufficiently 'patient-centred.'

Most trials gather procedural and result in data, but it is unclear if the patient experience of trial participation is consistently assessed. The drug development companies in Bangaloreperform a systematic scoping analysis of papers that reported standardized assessments of patient experience of trial participation.

Importance ofClinical Trial Feedback:

Clinical trials, in their purest form, are intended to examine the outcomes of human volunteers under "experimental" circumstances that the scientist controls. In contrast, no interventional research designs include the investigator measuring but not influencing the exposure of interest.

Medical research is an evident form of social good since it examines the efficacy of innovative medicines that have the potential to enhance and save lives. Although the impact of novel therapies and drugs and health outcomes may be detected, "there is no consensus on the optimal approach of conveying research findings" or informing trial participants of results.

Surprisingly, this fundamental protection inpatient research has weaknesses. In reality, the investigator has little knowledge of the dangers and benefits of intervention because this is the study's paradoxical goal.

Consent still presents challenges, as evidenced by research participants' lack of knowledge and self-reported unhappiness with the procedure. This has inspired investigations into ways to increase participant comprehension of consent papers and processes.

A clinical trial design is frequently preferred because it allows for the randomization of the intervention, thereby reducing the selection bias caused by an imbalance of unknown/immeasurable confounders.

This intrinsic strength includes the ability to uncover causation in an RCT. Randomized clinical trials, on the other hand, are nevertheless susceptible to flaws like misclassification and information bias.

The Communication That Works:

Pre-clinical research includes animal studies as well as evaluations of drug manufacturing and purity. Animal studies investigate:

1) the drug's safety at doses comparable to approximated human exposures.

2) pharmacodynamics (i.e., mechanisms of action and the relationship between drug levels and clinical response).

3) pharmacokinetics (i.e., drug absorption, distribution, metabolism, excretion, and potential drug-drug interactions).

If the medication is to be researched into further fellow humans, these data must be submitted for IND clearance.

The bulk of clinical trials done in Europe and the United States are publicized and publicly available on worldwide databases for the curious participant. However, with an estimated 25% of the European and US populations classified as ‘scientifically illiterate,' deciphering the significance of clinical studies can be difficult and even infuriating.

As a result, the new EU Clinical Studies Regulation, which is set to take effect in 2019, contains a requirement for all researchers to give summary results of all clinical trials in a manner and style that 'laypeople' can understand.


Massive volumes of research have been devoted to eliminating obstacles to clinical research participation, but less has been devoted to engaging current participants. There is no agreed-upon best practice, and trial managers are encouraged to figure out the best ways to communicate with their individual cohorts.

Engaging and enlightening participants about the findings of the study are more than simply a show of respect; it can also be a useful and successful strategy in motivating individuals and their larger communities to participate in future research.
