Executive view
NCT04184882 evaluates Bocidelpar in Muscular Dystrophy, Duchenne. The disclosed sponsor is Astellas Pharma, Inc., the design is Interventional, and the geographic footprint is United States. The first listed primary endpoint is Number of participants with Treatment Emergent Adverse Events (TEAEs), assessed over Up to Week 28.
The key landscape question is whether this protocol can generate a clinically interpretable signal relative to nearby programs. Phase alone is not a measure of evidence quality. Endpoint relevance, comparator choice, masking, enrollment feasibility, patient selection, country coverage and follow-up must be considered together.
PatSnap MCP Servers make this assessment reproducible by keeping protocol facts, result evidence, asset attributes and sponsor identity in separate structured calls.
How the MCP evidence stack was assembled
Clinical Trials MCP clinical_trial_fetch retrieved the design, outcomes, phase, status, enrollment, sponsor, countries and timing for NCT04184882 and selected peers. clinical_trial_result_fetch supplied detailed result records from the wider Muscular Dystrophy, Duchenne landscape. Drug & Asset MCP drug_fetch was queried for Bocidelpar, while Company & Deal Intelligence MCP organization_fetch was queried for Astellas Pharma, Inc..
This separation reduces a common diligence error: treating a registry label, a company description or a result excerpt as if each represented the complete evidence package. Explore the source workflow at the PatSnap MCP marketplace.

The table aligns endpoints, sponsors, phases, geographies and readout proxies. It is descriptive, not a head-to-head efficacy comparison. Differences in population, baseline risk, intervention schedule and follow-up can dominate apparent cross-trial differences.

Protocol design and endpoint interpretation
NCT04184882 is a Phase 1, terminated study with not reported planned participants. Allocation is Randomized, masking is Quadruple, and the intervention model is Parallel Assignment.
The primary endpoint is “Number of participants with Treatment Emergent Adverse Events (TEAEs)” over “Up to Week 28.” The retrieved endpoint description is: An AE is any untoward medical occurrence in a subject administered an investigational product (IP), and which does not necessarily have to have a causal relationship with this treatment. A TEAE is defined as an AE observed after starting administration of the investigational product (IP) to 28 days after the last dose of IP for the double blind part or moving to the open-label extension part, whichever comes first. An IP-related TEAE is defined as any TEAE with a causal relationship of "yes" by the investigator..
Interpretation should test whether the endpoint captures a clinically meaningful change, whether its time horizon matches the proposed biology, and whether treatment discontinuation or missing data can bias the estimate. The planned enrollment of not reported should be assessed against expected effect size, event frequency, multiplicity, subgroup plans and attrition.
The protocol identifies Bocidelpar as control therapy. A placebo comparator can strengthen internal efficacy assessment, while an active comparator may better test clinical differentiation. Single-arm and open-label programs require greater weight on objective outcomes, independent assessment and external benchmarks.
Indexed readouts in the surrounding landscape
0 recent result records were selected as contextual evidence for Muscular Dystrophy, Duchenne. These records do not establish direct evidence for NCT04184882 unless the registration number matches.
Indexed evidence status
No directly comparable result record was retrieved for this disease query. This is a monitoring gap, not evidence of absence.
Result fields should be reconciled with the source record before quantitative comparison. Population definitions, analysis sets, dose cohorts, estimands, confidence intervals, rescue therapy and follow-up can materially change the meaning of a numerical endpoint. Clinical Trials MCP supports repeatable refreshes as result records change.
Asset and sponsor context
Bocidelpar is indexed as Small molecule drug with PPARδ biology and a global stage of Discontinued. The asset profile lists Astellas Pharma, Inc. as an originator or developer.
Astellas Pharma, Inc. is indexed in an unreported country with the website http://www.astellas.com. Astellas Pharma develops and commercializes prescription medicines across therapeutic areas. The record lists 115 development-stage drug assets.
For execution diligence, monitor sponsor ownership, collaborator additions, site expansion, protocol amendments and enrollment revisions. A change in ownership or geography can alter operational confidence as well as the commercial meaning of a future readout.
Development white space
- Endpoint white space. Determine whether a more patient-relevant outcome, longer durability window or blinded central assessment would resolve uncertainty left by the current endpoint.
- Population white space. Test biomarker-defined, treatment-line or risk-stratified subgroups where effect size and unmet need could be clearer.
- Comparator white space. Identify whether the study can support differentiation against the current standard of care rather than only activity against baseline or placebo.
- Geographic white space. Assess whether the disclosed footprint supports recruitment, regulatory transferability and commercial generalizability.
- Sequencing white space. Clarify whether Bocidelpar is intended for monotherapy, combination, maintenance, rescue or an earlier treatment line.
White space should be framed as an unanswered development question, not merely an unoccupied mechanism label. A credible program closes a measurable clinical uncertainty with a design that can be executed and interpreted.
Strategic implications and next readouts
For sponsors, the endpoint hierarchy, safety window, enrollment pace and protocol amendment history should all support the same target product profile. Advancement criteria should be set before the readout and tied to clinical effect, uncertainty, tolerability and operational feasibility.
For business-development teams, differentiation may come from a sharper population, stronger comparator, more durable benefit, simpler delivery or clearer sequencing role. For investors, the central risk is evidence quality relative to time and capital, not the phase label in isolation.
Track recruitment status, enrollment changes, primary-completion timing, endpoint revisions, new result records, sponsor ownership and collaborator changes. Re-run the PatSnap MCP workflow when a surrogate becomes a clinical outcome, a single-country study expands, the comparator changes or a new result materially shifts the competitive benchmark.
