Risk management
Methods to examine clinical safety
The methods used to evidence the medical device clinical safety are based on preclinical and clinical data analysis, and the acceptability of the benefit/risk ratio derived from this analysis.
The results obtained performing the activities described at the R-TF-007-002 PMCF plan
are the inputs to analyse the clinical safety and the emerging risks that could be detected according to our GP-013 Risk management
procedure.
Acceptability of the benefit-risk ratio
The risk/benefit acceptability is based on the analysis of the possible risks of the product in relation to its benefits.
Once per year, the conclusions extracted from the preclinical and clinical data analysis will be used to confirm the benefit/risk ratio of the device. This analysis will be drafted in the T-015-002 Preclinical and clinical evaluation record
and T-015-003 Clinical evaluation report
.
The parameters used to determine, based on the state of the art, the global acceptability of the benefit/risk ratio for the intended purpose of the device are:
- No adverse effects should be found in the preclinical data evaluation.
- Current literature should support the usage of AI on the manufacturing process and should evidence the clinical benefits of the use of the device.
- Current literature should also show the feasibility of the device in comparison with current alternatives and solutions. The advantages of the device (PMCF activity 2) should be clear.
- No significant risks should be identified in relation to patient safety.
- The positive impact of the device should be strongly evidenced on the performance and the feedback obtained (PMCF activities 2 and 4).
- The use of the device as a skin structure assessment support tool, should be proven necessary due to its multiple advantages. Based on the device's characteristics, the device should not have side-effects specifically related to its use and should have a high benefit/risk ratio.
Benefit-risk issues relating to specific components
This section does not apply to the device as there are no specific additional components on it.
Clinical development plan
As required by the MDR 2017/745, we continuously generate, collect, analyse and assess the clinical data related to the device in order to verify the safety and performance, evaluate the undesirable side-effects and the acceptability of the benefit-risk ratio throughout the device's life cycle. We plan, conduct and document a clinical evaluation in accordance with the requirements established in the MDR (Article 61 and Annex XIV Part A) and following the Guidelines MEDDEV 2.7/1, MDCG 2020-1 and MDCG 2020-5.
Data identification and selection
Sufficient amount and quality of data shall be identified and analyzed to build relevant evidence that allows performing a non-biased and objective assessment of whether the device under evaluation is safe and achieves the intended clinical benefits, when used as intended by the manufacturer. This is performed through:
- Analysis of preclinical data to identify:
- Applicable and/or harmonized standards, according to the Technical File.
- Related and/or governmental publications that may be observed in relation to the product.
- Similar devices that provide data related to similar features, previous experience, and similar:
- Intended use.
- Principles of operation (safety & performance).
- Functional elements.
- State of the art publications about the related medical fields, medical conditions, technology and available alternative treatments.
- Analysis of clinical data relating to the safety, performance, design characteristics and intended purpose of the device under evaluation and/or an equivalent device:
- Clinical investigation(s) of the device performed by the manufacturer.
- Clinical investigation(s) or other studies reported in scientific and clinical literature, of a device for which equivalence to the device can be demonstrated.
- Reports published in peer reviewed scientific and clinical literature on other clinical experience of either the device or a device for which equivalence to the device can be demonstrated.
- Clinically relevant information coming from post-market surveillance, in particular the post-market clinical follow-up.
Responsible evaluators
The process of data identification and selection is developed and executed by professionals with expertise in information retrieval and understanding of the scope of the clinical evaluation set out by us. More details about the clinical team can be found below.
Data sources
The evaluation of data is based on a critical and analytical assessment of the available literature. The different sources utilized are:
- Preclinical data:
- National and international institutions and medical devices regulatory bodies webs:
- https://www.aemps.gob.es/
- http://imdrf.org/safety/safety.asp
- https://www.medtecheurope.org/

- National and international institutions and medical devices regulatory bodies webs:
- Information generated by the manufacturer.
- Clinical data:
- Renowned journal databases to support scientific validity:
- Clinical trials registry platforms to identify relevant investigational studies:
Search filters
When using the search tool of specific websites or when searching in journal databases, at least the first 5 pages are considered for their further evaluation. If the same scientific publication appears under different search characteristics, the repeated source is ignored and the following source is analysed instead. The scientific and clinical publications are already sorted out by relevance. Moreover, a time filter (last 3 years) is applied in order to ensure that the most recent information is evaluated. Relevant citations referenced in the scientific and clinical literature already selected from the previous sources might also be considered for evaluation.
Research questions and keywords
The technical documentation of the device as well as the state of the art is used to develop the clinical research questions and keywords. The method PICO is chosen to help breaking down into four components the research questions. These identify the key problem of the patient, what treatment or tests are available for the patient, what alternative treatment or tests are being considered (if any) and what is the desired outcome to promote or avoid.
- P = Patient Population: it describes the most important characteristics of the patient. This may include the primary problem, disease, or co-existing conditions.
- I = Intervention, prognostic factor or exposure: it describes the main intervention, prognostic factor, or exposure.
- C = Comparator: it describes the main alternative to compare with the intervention. This can be different devices, tests or placebo. Sometimes the clinical question may not always have a specific comparison.
- O = Outcomes: it describes performance and safety a) What intervention wants to accomplish, measure, improve or affect. This can be to relieve or eliminate the symptoms or reduce the number of adverse events. b) Currently known risks or evidence on safety of the intervention or comparators.
Database search steps
The defined research keywords are used and the search filters are applied in the clinical data sources previously specified to retrieve relevant information allowing a systematic assessment of the available literature.
Step 1: Use PICO to formulate the search strategy.
# | Selectet terms | |
---|---|---|
1 | Patient population | Dermatosis, Skin cancer, Chronic skin conditions, inflamatory skin diseases, malignant skin lesions, pigmented skin lesions, melanoma, basal cell carcinoma, squamous cell carcinoma, atypical nevus, acne, psoriasis, urticaria, atopic dermatitis, onychomycosis, melasma, solar lentigo, dermatofibroma |
2 | Intervention | Clinical image, digital imaging, web application, smartphone, dermatoscopy, camera |
3 | Comparator | Artificial intelligence, machine learning, deep learning, computer vision, deep neural networks, convolutional neural networks, molescope, metaoptima, dermengine |
4 | Outcomes | Diagnosis, diagnosis support, followup, segmentation, detection, estimation, classification |

Patient population AND Intervention AND Comparator AND Outcomes (Performance OR Safety)
Scheme
# 1 AND # 2 AND # 3 AND # 4
Search
The combination of terms used for the search will be detailed at the report with the corresponding findings.
Step 2: Search parameters.
Randomized Control Trials (RCTs) are often considered the gold standard and represents the cornerstone of Evidence-Based Medicine (EBM) due to the rigorous methodology used. RCTs allow avoidance of bias related to confounding factors (through a control group), selection bias (through randomization) and interpretation bias (through double blinding). Moreover, they elementary aspects of the scientific report are included such as adequate statistical methods and controls. Likewise, meta-analysis studies provide high evidence, and clinical trials are considered to report high-quality data. Therefore, the search parameters are:
- Type of trials: randomized controlled trials, meta-analysis and clinical trials.
- Publication time: last 3 years (since 2021).
- Species: humans.
- Number of publications: all the results of the first 5 pages.
Additionally it is required to look at search details to look for contraindications and adverse events reported, meaning that "contraindication" OR "adverse event" should be considered in the search parameters established.
It is worth mentioning that we performed a previous clinical evaluation and databases search covering the period from 2012 to 2020 for our medical device placed on the market following the 93/42/EEC MDD regulation that can be consulted within its corresponding technical file.
Device equivalence
As described at the corresponding Device equivalence section of the GP-015 Clinical evaluation
procedure, the equivalence table from the Guideline MDCG 2020-5 is used to identify the supporting data to demonstrate device equivalence. We place emphasis on the differences between the device and an equivalent device rather than the similarities.
In line with the MDR 2017/745 requirements, we consider the following characteristics to claim device equivalence and compile them at the R-TF-015-003 Clinical evaluation report
:
1. Technical Characteristics (add a separate row for each of the assessed characteristics) | Device 1 (under clinical evaluation) Description of characteristics and reference to specifying documents | Device 2 (marketed device) Description of characteristics and reference to specifying documents | Identified differences or conclusion that there are no differences in the characteristic |
---|---|---|---|
Device is of similar design | 1.1 | ||
Used under similar conditions of use | 1.2 | ||
Similar specifications and properties including software algorithms | 1.3 | ||
Uses similar deployment methods where relevant | 1.4 | ||

Scientific justification why there would be no clinically significant difference in the safety and clinical performance of the device, OR a description of the impact on safety and or clinical performance (use one row for each of the identified differences in characteristics, and add references to documentation as applicable) | Clinically significant difference Yes / No |
---|---|
1.1 | |
1.2 |
2. Biological Characteristics (add a separate row for each of the assessed characteristics) | Device 1 (under clinical evaluation) Description of characteristics and reference to specifying documents | Device 2 (marketed device) Description of characteristics and reference to specifying documents | Identified differences or conclusion that there are no differences in the characteristic |
---|---|---|---|

---|---|
3.1 | |
3.2 |
Summary
In the circumstance that more than one non-significant difference is identified, we will provide a justification whether the sum of differences may affect the safety and clinical performance of the device.
For every single characteristic incorporated in the table, scientific justification must be elaborated to show that there is no clinically significant difference in the safety and performance of the device. For the identification of characteristics that may affect safety and for the assessment of equivalence regarding safety, we implement a risk-based approach.
Both favorable and unfavorable data from the device as well as from the devices for which equivalence can be demonstrated must be identified. This data may come from:
- Scientific and clinical literature
- Common specifications
- Harmonized standards
- Other established technical specifications
All this data progresses to data appraisal and analysis in order to evaluate whether they are providing sufficient clinical evidence for the purpose of confirmation of conformity with the applicable GSPR.
Data appraisal
Once the data is identified in the current literature, the content is appraised to evaluate its suitability for establishing the safety and performance of the device. The manufacturer's clinical team evaluates each piece of information taking into consideration three parameters: the methodological quality of work and scientific validity of the information, the relevance to the device and its intended use, and the contribution to the overall evaluation. Then, the clinical team accepts or rejects the data after applying the following weight-based system:
Data characteristics | Methodological quality Q | Relevance, R | Contribution, C | Weighted value, W (W=Q+R+C) | Appraisal data | Notes |
---|---|---|---|---|---|---|
Very relevant information in relation with the product and its intended use | Up to 40 | Up to 30 | Up to 30 | W ≥ 70 | Accepted | Pivotal data |
Relevant information in relation with the product and its intended use | Up to 40 | Up to 30 | Up to 30 | 30 < W < 70 | Accepted | Other data |
Little relevant information in relation with the product and its intended use | Up to 40 | Up to 30 | Up to 30 | W ≤ 30 | Rejected | No contribution, rejected |
These three indicators allow a systematic weighted evaluation:
- Methodological quality and scientific validity: examination of the methods used to generate and collect the data, and evaluate to which extent the observed outcomes are the result of the device/technology under evaluation or are due to confounding influences, bias, random error, inadequate disclosure of information or misinterpretation. The methodology is accepted when:
- Data is extracted from RCTs (Randomized Clinical Trials), meta-analysis and clinical trials, from publications based on scientific evidence or from previous experience on the market.
- The study design is adequate in terms of type, sample size, relevance of endpoints, randomization of patients, inclusion and exclusion criteria, stratification of patients, prognostic factors, follow-up, recording and reporting of serious adverse events, reliability of the methods used for quantifying outcomes, or procedures for retrieving complete information.
- Data consists of an adequate number of observations that can confirm or refute the claims of the device under evaluation.
- The methods for data processing and statistics are suitable.
- It complies with Good Clinical Practice (GCP) according to EN ISO 14155 or equivalent standards.
- The information is disclosed in an adequate manner, including summary, introduction, methods, results, discussion and conclusions.
- Relevance: examination of whether the data directly demonstrates adequate clinical performance and clinical safety of the device under evaluation, or whether the data serves as indirect supportive role. The information is relevant when:
- It is representative of the device under evaluation, including data concerning the medical conditions that are managed with the device, other devices and medical alternatives, or equivalent devices.
- The aspects covered are related to clinical safety and performance, claims, hazards and hazardous situations, management of risks, establishment of current knowledge and state of the art, determination and justification of the benefit/risk ratio and the acceptability of undesirable side-effects, or the determination of equivalence.
- It is representative to the intended purpose or claims of the device under evaluation.
- It is representative to the user group, patient population, medical indication, age group, gender, type and severity of the medical condition, or range of time.
- Contribution:
- Device and/or related techniques intended use. The contribution of the analyzed data in relation to the device or techniques features and in relation to the intended use must be strong and clear.
- Device and/or related techniques risk analysis. The contribution of the analyzed data in relation to the device or techniques risk analysis must be strong and clear, based on keywords definition.
On the other hand, the information is rejected when:
- There is a lack of information (only the abstract is available).
- The information comes from reviews, editorials or opinion papers.
- The study design and/or statistical methods are inadequate.
- The topic discussed is not related to the device and/or technology under evaluation.
- Bias or influencing factors are present (conclusions are inconsistent and can lead to misinterpretations).
- The information is inaccessible or repetitive.
Therefore, the information meeting the inclusion criteria and obtaining a value W > 30 after going through the weighted-based system will be accepted. On the contrary, the information with a value W ≤ 30 will be rejected. Proper justification for the decisions made, whether the information is accepted or rejected, must be given under the column named “DATA ANALYSIS AND CHARACTERISTICS EXTRACTION” of the T-015-002 Preclinical and clinical evaluation record
.
PMS and PMCF data appraisal
The PMS data will be analyzed according to the General Procedure GP-007 Post-market surveillance
. The same criterion, which is documented and structured in the Preclinical and clinical evaluation record (T-015-002 Preclinical and clinical evaluation record
), will be applied to identify, and select preclinical and clinical data from the available literature.
Periodically and according to the PMS and PMCF plans, the clinical evidence as well as new data will be revised, appraised, and evaluated objectively yearly to confirm the product's intended use, the acceptable benefit/risk ratio and the accomplishment of the GSPRs.
Clinical investigations
If necessary, generate, through properly designed clinical investigations in accordance with the MDR 2017/745 regulation and ISO 14155:2020 standard, any new or additional clinical data necessary to address outstanding issue.
As we explained at the GP-015 Clinical evaluation
procedure, we will carry out a clinical investigation study based on a Clinical Investigation Plan or Protocol (T-015-004 Clinical Investigation Plan (CIP)
) and a investigator brochure (T-015-005 Investigator's Brochure
). The results will be documented in the Clinical Investigation Report (T-015-006 Clinical Investigation Report (CIR)
).
As established in the Guideline MEDDEV 2.7/1, the clinical evaluation will identify aspects that need to be addressed systematically during post-market through the clinical investigations, as well as through the post-market surveillance and other post-market clinical follow-up studies. Aspects such as residual risks, any uncertainty or unanswered question, rare complications, uncertainties regarding long-term performance and/or safety under wide-spread use will be evaluated during post-market. Moreover, the planned clinical investigations will generate clinical evidence to support scientific validity and clinical performance, as stated in the Guideline MDCG 2020-1.
Proof of concept studies or other studies
Proof of concept studies will generate clinical evidence to support scientific validity and technical performance, as indicated in the Guideline MDCG 2020-1. The ones that are planned are detailed at the R-TF-015-008 Clinical development plan_2023_002
.
Data analysis
The data accepted from the appraisal is analyzed in order to reach conclusions about the safety and clinical performance of the device including its clinical benefits and possible adverse events.
Data analysis is performed qualitatively, although some aspects can be analyzed quantitatively such as the number of incidents or serious adverse events. The appraised data is evaluated to find consistency of results related to performance and safety characteristics, risks and benefits to patients, users and other persons associated with the intended purpose of the device under evaluation, and the confirmation of usability.
Moreover, following the MDCG 2020-1, three key components are taken into consideration to analyze the clinical evidence of the device:
- Valid clinical association: the extent to which the software's output, based on the inputs and algorithms selected, is associated with the targeted physiological state or clinical condition defined in the intended purpose.
- Evidence generated through the previous literature research, proof of concept studies or manufacturer's own clinical investigations/clinical performance studies.
- Technical performance: ability to accurately, reliably and precisely generate the intended output from the input data (principle of operation).
- Evidence generated through verification and validation activities.
- Clinical performance: ability to yield clinically relevant output in accordance with the intended purpose. It assesses clinical safety, effectiveness and performance. It supports the demonstration of clinical benefits against foreseeable or known risks associated with the product (benefit/risk ratio acceptability) and compared with current processes, expected benefits and diagnostic/therapeutic/monitoring improvements.
- Evidence generated through device equivalence in the target population and for the intended use, contraindications and undesirable effects, and through clinical investigations.
Lastly, it is analyzed the alignment and consistency between the current knowledge and state of the art, the clinical evaluation, the information materials supplied by the manufacturer, and the risk management documentation for the device under evaluation.
GAP analysis
We carry out a gap analysis to confirm whether the existing data are sufficient to verify that the device under evaluation is in conformity with the applicable GSPR. As a result of this gap analysis, the creation of new clinical data may be considered necessary.
