The pith
A cluster of 23 trials from CinnaGen and Orchid Pharmed shows 180 problems indicating that analyses were engineered to support regulatory approval.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
Application of the INSPECT-SR trustworthiness framework to the 23 trials identified 180 problems across nine categories, with the most common being reporting failures, arithmetic violations, design flaws, registration irregularities, and statistical errors. Co-authorship networks show that trial design, data management, and manuscript preparation were concentrated inside the sponsoring organisation. The paper argues that domestic publication incentives, commercial pressure from international sanctions, and regulatory requirements for local trial evidence together produced this pattern of genuine trials with manipulated analyses.
What carries the argument
The INSPECT-SR trustworthiness framework, which checks published trial reports against original study records for inconsistencies in design, registration, statistics, reporting, and authorship concentration.
If this is right
- Regulatory bodies such as the EMA should treat the published evidence from this cluster as unverified until they obtain independent access to individual participant data.
- The term clinical trial engineering should be used to distinguish this practice from classical paper mills that fabricate data outright.
- Similar clusters may exist in other settings where domestic production incentives and regulatory reliance on local trials coincide.
- Co-authorship concentration within a single sponsor organisation is a structural marker that warrants closer inspection in future reviews.
Where Pith is reading between the lines
- Sanctions that block imported drugs can create domestic pressures that affect the integrity of the supporting clinical evidence.
- Other manufacturers operating under comparable economic and regulatory constraints may show overlapping patterns if examined with the same framework.
- Wider adoption of mandatory raw-data sharing in regulatory submissions could reduce the scope for such engineered analyses.
- The approach could be tested on trial sets from additional countries facing strong publication or import-substitution incentives.
Load-bearing premise
The 180 identified problems indicate deliberate statistical manipulation engineered for regulatory approval rather than honest reporting differences or unintentional errors.
What would settle it
Independent reanalysis of the original individual participant data from these 23 trials that confirms the published statistical results and conclusions would show the problems do not reflect manipulation.
read the original abstract
Paper mills produce fraudulent research manuscripts built on recycled tables and figures, or on entirely fabricated data. A more recent pattern has emerged: apparently genuine trials with real patients, but with manipulated statistical analyses engineered to support regulatory approval while remaining plausible to peer reviewers. This analysis applies the INSPECT-SR trustworthiness framework to 23 randomised controlled trials and post-marketing studies linked to CinnaGen Co., Iran's largest biosimilar manufacturer, and its clinical operations subsidiary Orchid Pharmed. Papers were retrieved from PubMed and assessed against the original study records. A total of 180 problems were identified across nine categories. The five most frequent issues were reporting failures (n=37), arithmetic violations (n=28), design flaws (n=26), registration irregularities (n=25), and statistical errors (n=25). Analysis of the co authorship network shows that trial design, data management, and manuscript preparation were concentrated within the sponsoring organisation. The underlying structural drivers appear to be a convergence of domestic publication incentives, commercial pressure from international sanctions that created demand for domestically produced drugs, and regulatory pathways that require this body of trial evidence. Because this pattern differs fundamentally from classical paper mills, we propose the term clinical trial engineering to describe it. Regulatory bodies, including the European Medicines Agency (EMA), should treat published clinical evidence from this cluster as unverified until independent access to individual participant data is granted

A structured set of objections, weighed in public.
Referee Report
Summary. The manuscript applies the INSPECT-SR trustworthiness framework to 23 randomised controlled trials and post-marketing studies associated with CinnaGen Co. and Orchid Pharmed. It reports 180 problems across nine categories (most frequent: reporting failures n=37, arithmetic violations n=28, design flaws n=26, registration irregularities n=25, statistical errors n=25), documents concentrated co-authorship within the sponsoring organisation, and attributes the pattern to domestic publication incentives, sanctions-driven commercial pressure, and regulatory requirements for biosimilar approval. The authors introduce the term 'clinical trial engineering' to distinguish this from classical paper mills and recommend that regulators including the EMA treat the published evidence as unverified pending independent access to individual participant data.
Significance. If the methodological details and causal interpretation can be strengthened, the work would provide a concrete case study of a distinct pattern of research integrity issues in industry-sponsored biosimilar trials. The network analysis and category counts could inform targeted regulatory scrutiny and the development of domain-specific extensions to existing trustworthiness frameworks. The proposal of 'clinical trial engineering' as a new descriptor is potentially useful for distinguishing manipulated but patient-containing trials from outright fabrication.
major comments (3)
- [Abstract and Methods] Abstract and Methods: The central claim that the 180 identified problems constitute 'clinical trial engineering' engineered for regulatory approval rests on the assertion that papers were 'assessed against the original study records,' yet no selection criteria for the 23 trials, per-trial breakdown of issues, verification protocol against raw data, or inter-rater reliability statistics are supplied. This leaves the counts vulnerable to selection bias and framework misapplication, directly undermining the inference to deliberate manipulation rather than reporting differences or honest errors.
- [Results] Results: The five most frequent problem categories are presented as aggregate counts without examples of how individual issues were scored, whether arithmetic violations were confirmed by re-analysis of participant-level data, or any comparison to a control set of non-CinnaGen biosimilar trials. Without this disambiguation, the evidence does not yet distinguish the proposed pattern from limitations in applying INSPECT-SR or from unintentional reporting inconsistencies.
- [Discussion] Discussion: The regulatory recommendation that EMA and similar bodies treat the evidence cluster as unverified until IPD access is granted follows from the structural-driver analysis, but the manuscript provides no direct test (e.g., re-analysis of a subset of trials or comparison with trials from other manufacturers under similar sanctions) to support the causal attribution over alternative explanations such as resource constraints or differing local reporting standards.
minor comments (2)
- [Results] The co-authorship network description would benefit from a supplementary table listing the 23 trials with their PubMed IDs, problem counts per category, and key network metrics to allow readers to trace specific contributions.
- [Methods] Clarify whether the INSPECT-SR framework was applied verbatim or adapted for biosimilar post-marketing studies, and cite the exact version or reference used.

Referee: [Abstract and Methods] Abstract and Methods: The central claim that the 180 identified problems constitute 'clinical trial engineering' engineered for regulatory approval rests on the assertion that papers were 'assessed against the original study records,' yet no selection criteria for the 23 trials, per-trial breakdown of issues, verification protocol against raw data, or inter-rater reliability statistics are supplied. This leaves the counts vulnerable to selection bias and framework misapplication, directly undermining the inference to deliberate manipulation rather than reporting differences or honest errors.
Authors: We agree that the Methods section requires greater detail to support the claims. The 23 trials represent all PubMed-retrievable randomised controlled trials and post-marketing studies associated with CinnaGen Co. and Orchid Pharmed at the time of the study. In revision, we will add explicit selection criteria, a supplementary table providing per-trial issue counts, and a protocol describing how reported data were cross-checked against available study records. Inter-rater reliability was not formally quantified because the assessment was led by one author with framework expertise and reviewed by co-authors; we will state this limitation explicitly. These changes will allow readers to assess potential bias and the consistency of INSPECT-SR application. revision: yes

Referee: [Results] Results: The five most frequent problem categories are presented as aggregate counts without examples of how individual issues were scored, whether arithmetic violations were confirmed by re-analysis of participant-level data, or any comparison to a control set of non-CinnaGen biosimilar trials. Without this disambiguation, the evidence does not yet distinguish the proposed pattern from limitations in applying INSPECT-SR or from unintentional reporting inconsistencies.
Authors: We will revise the Results section to include illustrative examples for each major category, showing how issues such as arithmetic violations were identified from published tables and, where feasible, verified by recalculation of summary statistics. Full participant-level data were unavailable for most trials, which itself underscores the need for IPD access. A matched control set of non-CinnaGen biosimilar trials lies outside the scope of this focused case study; we will note this as a limitation and indicate how such a comparison could be pursued in future work to further isolate the observed pattern. revision: partial

Referee: [Discussion] Discussion: The regulatory recommendation that EMA and similar bodies treat the evidence cluster as unverified until IPD access is granted follows from the structural-driver analysis, but the manuscript provides no direct test (e.g., re-analysis of a subset of trials or comparison with trials from other manufacturers under similar sanctions) to support the causal attribution over alternative explanations such as resource constraints or differing local reporting standards.
Authors: The causal framing is interpretive, grounded in the concentration of issues within this manufacturer cluster alongside known Iranian regulatory and economic pressures. We will expand the Discussion to address alternative explanations, including resource limitations and local reporting norms, and clarify why the specific combination of design, statistical, and registration problems is more consistent with systematic engineering than isolated errors. A direct test via re-analysis or cross-manufacturer comparison would require participant-level data and additional trial sets that are not accessible to us; the IPD recommendation is therefore offered as a precautionary regulatory step based on the documented volume of issues rather than as a proven causal demonstration. revision: yes
- Direct re-analysis of participant-level data subsets or systematic comparison against trials from other manufacturers under comparable sanctions, as these steps require raw data access unavailable to the authors.
Circularity Check
Empirical literature analysis with no derivations, equations, or self-referential reductions
full rationale
The paper applies the external INSPECT-SR framework to count and categorize 180 problems across 23 trials, reports co-authorship network observations, and proposes a descriptive term. No mathematical derivations, fitted parameters, predictions, or first-principles results are claimed. No equations exist that could reduce to inputs by construction. No self-citations are invoked as load-bearing uniqueness theorems or ansatzes. The analysis is self-contained against the external framework and the retrieved study records; conclusions follow directly from the tabulated counts and network description without circular reduction. This matches the default expectation for non-circular empirical work.
