Barriers for conducting clinical trials in developing countries—A systematic review
Open accessAbstract
BACKGROUND: Clinical trials for identification of efficient and effective new diagnostic and treatment modalities are needed to address disproportionately high burden of communicable (e.g., HIV/AIDS, tuberculosis, and malaria) and non-communicable diseases (e.g., diabetes) in developing countries. However, gross under-representation in global clinical trial platforms contributes to sustained health inequity in these countries. We reviewed the literature on barriers facing clinical researchers in developing countries for conducting clinical trials in their countries. METHODS: Literature indexed in PubMed, Embase, CINAHL and Web of Science, WHO Global Health Library were searched. Grey literature was also searched. Search key words included barriers, challenges, clinical trials and developing countries. Articles within the scope of this review were appraised by two reviewers. RESULTS: Ten studies, which are reported in 15 papers, were included in this review. Following critical review we identified five unifying themes for barriers. Barriers for conducting clinical trials included lack of financial and human capacity, ethical and regulatory system obstacles, lack of research environment, operational barriers and competing demands. CONCLUSION AND RECOMMENDATION: There were substantial barriers at system, organization and individual level. We propose that to address this problem, instituting a system for wider implementation of local investigator-initiated trials is warranted. These trials are more applicable to local populations because they build on local healthcare knowledge. They are more demand-led, influence policy and responsive to a country's needs because they are driven by a local or national agenda.

TL;DR
This systematic review identifies five unifying barriers to conducting clinical trials in developing countries: lack of financial and human capacity, ethical and regulatory obstacles, lack of research environment, operational barriers, and competing demands. The authors argue that wider implementation of local investigator-initiated trials is warranted to address these system-, organization-, and individual-level barriers.
Key findings
- Ten studies reported in 15 papers were included; 1,915 titles/abstracts were screened and 1,900 were excluded as out of scope.
- Five barrier themes were identified: lack of financial and human capacity; ethical and regulatory system obstacles; lack of research environment; operational barriers; and competing demands.
- Lack of funding was reported across all included articles except two studies conducted in Saudi Arabia; lack of skilled personnel and lack of awareness/motivation were also reported as human-capacity barriers.
- Of four quantitative studies, one was high quality, two medium, and one low; one medium-quality study had a 23% response rate (92/404), and the low-quality study had a 27% response rate.
- The paper states that less than 20% of clinical trials are conducted in developing countries and only 1% of recently discovered drugs target tropical diseases.
Methods
- Systematic review following PRISMA, searching PubMed, Embase, CINAHL, Web of Science, and WHO Global Health Library, plus grey literature sources including ProQuest Dissertations and Theses and Google Scholar.
- Eligibility: empirical, peer-reviewed studies published in English between 1995 and October 2015 that reported barriers/challenges for conducting clinical trials in developing countries; commentaries, editorials, and literature reviews were excluded.
- Two reviewers independently screened, appraised quality using adapted Newcastle-Ottawa criteria for quantitative studies and Kuper criteria for qualitative studies, and synthesized findings using thematic analysis/synthesis.
Limitations
- Stated: most developing countries were hardly represented; barriers may vary by context, so findings may not reflect any specific country; limited articles meant similarities and differences among developing countries were not examined; most included studies were qualitative with small samples and narrow participant diversity; non-English papers were excluded because translation was not feasible.
- Evident: only 10 studies (15 papers) met inclusion criteria, and the authors did not conduct a meta-synthesis because of diverse settings and methodological approaches.
- Evident: quality assessment found one low-quality quantitative study with high risk of selection bias and low response rate, and one qualitative study/proposal did not describe key qualitative aspects such as approach, data collection, analysis, and interpretation.

“There were, however, a considerable variation regarding lack of time as a barrier, with most (3 out of 4) studies that reported views of health professionals [40, 51, 53] putting more emphasis on lack of time and only one study [48] that involved clinical researchers reporting lack of time as a barrier.”

“While this has increased opportunities to generate locally relevant evidence, clinical research in LMICs also faces social, cultural, political, and infrastructural challenges that influence community engagement and trial implementation [2, 4–6].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
