When More Clinical Evidence Is Needed: DE 490 Article 42
Updated: 2026-11-11 · GRZAN Regulatory Team · Verification date 2026-10-20
1. Key takeaways
Article 42 of Decreto Ejecutivo N° 490 provides that, whatever the risk class of the device, one of six situations will require a more rigorous inspection and/or the submission of more clinical evidence. The six are: the device uses innovative technology; the manufacturer states a new purpose or a purpose different from the use described in earlier assessments; the device is new to the manufacturer; that type of device tends to be associated with an excessive number of adverse events, including use error; the device contains innovative materials or potentially hazardous materials; and the device raises a public health concern.
The trigger is deliberately independent of classification. A class A device that uses an innovative technology or an innovative material is caught by the same article as a high-risk implant, so the reflex that a lower class means a lighter file does not hold in these six cases. The provision is best read as a screening tool applied before the file is assembled, not as a query that arrives during review.
- Six triggers under Article 42, applying regardless of risk class.
- The triggers are alternative, not cumulative: any one of them is sufficient.
- The consequence is a stricter inspection and/or more clinical evidence, not automatic refusal.
- Novelty is measured against the manufacturer experience, not against the market.
- A change of intended purpose interacts with the major change rules under Article 43.
2. Legal basis
The provision is Article 42 of Decreto Ejecutivo N° 490 of 4 October 2019. It operates alongside the clinical requirements of Article 37, the definitions of clinical investigation and of the clinical summary in Article 2, and the manufacturer support letter mechanism in Article 25.
| Document | Provision | Point of substance |
| Decreto Ejecutivo N° 490 (4 October 2019) | Article 42, opening text | Independientemente del riesgo del dispositivo médico, las siguientes situaciones requirirán de una inspección más rigurosa y/o la presentación de más evidencia clínica: regardless of the risk of the device, the following situations require a more rigorous inspection and/or the submission of more clinical evidence |
| Same | Article 42, item 1 | The device uses innovative technology |
| Same | Article 42, item 2 | The manufacturer states a new purpose, or a purpose different from the use described in earlier assessments |
| Same | Article 42, item 3 | The device is new to the manufacturer |
| Same | Article 42, item 4 | That type of device tends to be associated with an excessive number of adverse events, including use error |
| Same | Article 42, item 5 | Contains innovative materials or potentially hazardous materials |
| Same | Article 42, item 6 | The device raises a public health concern |
| Same | Article 37, item 3(a) | Class C: summary of clinical studies or trials on safety and effectiveness |
| Same | Article 37, item 4(c) | Class D: detailed information on clinical and preclinical safety and effectiveness |
| Same | Article 2, definition 86 | Definition of the summary of safety and effectiveness of a clinical study, covering the objective, design, sample size, blinding, randomisation, arms, duration, population characteristics and evaluation variables |
| Same | Article 2, definition 51 | Clinical investigation: any study on human subjects carried out to discover or verify the clinical effect of a device or to identify adverse reactions |
| Same | Article 25 | Manufacturer support letter: where the technical literature does not cover some items of the Ficha Técnica, a manufacturer letter may supplement it, with no limit on the number of points |
The six situations are drafted as alternatives. Nothing in the text requires more than one to be present, and nothing limits the article to devices above a particular class, which is the point of the opening words.
3. Expert insights
Insight one: Article 42 is a cross-class trigger, so a low-risk product can also be subjected to enhanced review. The key phrase is the opening reference to regardless of risk. A class A device that uses innovative technology or innovative materials is caught in the same way. The article breaks the habitual assumption that low risk means low requirements, and it is the risk point most easily overlooked when a class A file is being prepared.
Insight two: item 3, the device being new to the manufacturer, is a highly subjective standard. The text reads: when the device is new for the manufacturer. The test is not first placement on the market but the experience of that particular manufacturer. A company entering a product category for the first time may trigger enhanced review even where the category itself is mature in the market. A manufacturer new to a category should therefore assume enhanced review and prepare the additional evidence accordingly.
Insight three: item 2 connects directly with change management. The wording covers a purpose declared by the manufacturer that is new or different from the use described in earlier assessments, and an extension of indications is precisely that situation. Read with Article 43, which treats the use, whether new or extended, and the addition or removal of any contraindication, as a substantial change to the device, the conclusion is that extending a use is both a substantial change and a trigger for enhanced review. The two apply cumulatively rather than in the alternative.
Insight four: Article 25 provides a formal remedy where the evidence is thin. Where the manufacturer technical literature submitted by the supplier does not demonstrate, at certain points, that the product complies with the CTNI Ficha Técnica, the DNDM may accept a duly authenticated manufacturer support letter (carta de sustentación) in the DNDM format. The text adds that no limits will be set on the number of points the manufacturer may supply. Read with Article 42, the mechanism is significant: where more evidence is needed, the manufacturer support letter is a supplementary route with no numerical cap.
4. Practical recommendations
- Screen the product against the six items of Article 42 at project set-up, and where any one is met, assume an enhanced review cycle and budget the additional evidence.
- Where the company is entering a category for the first time, assume enhanced review under item 3 and prepare clinical and post-market data on comparable products in advance.
- Before extending a use, assess both Article 42, item 2 and Article 43, and plan for the two obligations rather than for one.
- Where the technical literature cannot cover an item in the Ficha Técnica, use the manufacturer support letter under Article 25, remembering that the number of points is not capped.
- Organise the clinical evidence package according to the structure of definition 86, covering objective, design, sample size, blinding, randomisation, arms, duration, population and variables.
- Record the outcome of the six-item screen in the file, so that the assessment is visible if the authority raises the question later.
5. Verification checklist
