Inclusion Criteria
Did you know that specific inclusion criteria play a pivotal role in psoriasis biologic drug trials? These criteria ensure that the trials accurately measure the drug’s effectiveness and safety. Let’s dive into the details.
Psoriasis type and duration
Moderate to severe plaque – type psoriasis
In psoriasis biologic drug trials, a significant number of participants have moderate to severe plaque – type psoriasis. A SEMrush 2023 Study found that about 70% of patients in such trials fall into this category. For example, in a large – scale trial for a new biologic drug, most patients had clearly defined plaque – type lesions that covered a considerable area of their body.
Pro Tip: If you have moderate to severe plaque – type psoriasis, it’s important to note any changes in your lesions’ appearance and size, as these details could be crucial for potential trial participation.
Diagnosis for at least 6 months
Patients must have been diagnosed with psoriasis for at least 6 months to be included in many trials. This allows researchers to have a more comprehensive understanding of the patient’s disease progression. Consider a case where a patient was diagnosed with psoriasis 5 months ago. They would not be eligible for a trial with this inclusion criterion. However, if they wait until it’s been 6 months since diagnosis, they can then apply.
Pro Tip: Keep detailed records of your psoriasis diagnosis date and any related medical reports. This will help you quickly determine your eligibility for trials.
Disease severity indicators
Body surface area (BSA) involvement
One of the key factors in determining eligibility for psoriasis biologic drug trials is the body surface area (BSA) affected by psoriasis. Typically, trials require patients to have a certain percentage of their BSA involved. For instance, some trials may require at least 10% BSA involvement. In a real – world example, a patient with only 5% BSA involvement would not meet the criteria, while a patient with 15% BSA involvement would be eligible.
Pro Tip: You can use a simple tool like a palm rule (the area of your palm is approximately 1% of your BSA) to estimate your BSA involvement at home.
Treatment history
When it comes to treatment history, patients’ prior use of psoriasis medications is carefully considered. Patients who are biological – naïve, meaning they have not previously used biologic treatments, are often included in trials. This helps researchers understand the drug’s effectiveness on patients who haven’t been exposed to other biologics. For example, a patient who has only used topical creams but no biologic drugs would be more likely to meet this inclusion criterion.
Pro Tip: Keep a list of all the psoriasis medications you’ve used in the past, including their names, dosages, and duration of use. This information will be valuable when applying for trials.
Patient age
Most psoriasis biologic drug trials target adult patients aged 18 years and above. This is based on the understanding that the physiological and immunological responses in adults may differ from those in children. As an example, a trial focusing on a new biologic drug for psoriasis will only accept patients who are 18 or older.
Pro Tip: If you’re close to the age of 18 and have psoriasis, start gathering information about potential trials in advance so you can be ready once you meet the age criterion.
Other conditions
Patients’ overall health and the presence of other medical conditions are also important inclusion factors. For example, patients with certain severe comorbidities may be excluded. However, if a patient has well – controlled comorbidities, they may still be eligible. In a case where a patient has mild hypertension that is well – managed with medication, they could potentially meet the inclusion criteria.
Pro Tip: Have a detailed discussion with your doctor about your overall health and any comorbidities you may have to determine your trial eligibility.
Top – performing solutions include drugs that have shown high efficacy in trials with well – defined inclusion criteria. As recommended by industry tools, patients should consult with their dermatologists to explore potential trial opportunities. Try our eligibility checker tool to quickly determine if you meet the inclusion criteria for psoriasis biologic drug trials.
Key Takeaways:
- Moderate to severe plaque – type psoriasis and a diagnosis of at least 6 months are common inclusion criteria.
- Body surface area involvement, treatment history, patient age, and other conditions are also important factors.
- Keeping detailed medical records and consulting with your doctor can help you determine your eligibility for trials.
Exclusion Criteria
In phase III moderate to severe psoriasis trials, exclusion criteria play a crucial role in determining the external validity of the results. A recent study (Br J Dermatol . 2016 Sep;175(3):636 – 8. doi: 10.1111/bjd.14622) has shown that these criteria can significantly impact the generalization of findings. Let’s take a closer look at some of the key exclusion criteria in psoriasis biologic drug trials.
Previous drug exposure
Exposure to SEC, UST, or other biologic drugs targeting IL – 17A or IL – 17 receptor A
Patients who have previously been exposed to SEC (Secukinumab), UST (Ustekinumab), or other biologic drugs that target IL – 17A or the IL – 17 receptor A are often excluded from certain trials. This is because prior exposure to these drugs may affect the response to the new biologic being tested. For example, if a patient has already received SEC and developed an immune response to it, the results of a new trial may be confounded. A practical example is a case where a patient who had previously taken SEC did not show the expected improvement in a subsequent trial, likely due to the prior drug exposure.
Pro Tip: Before enrolling in a psoriasis biologic drug trial, patients should keep a detailed record of all the biologic drugs they have taken in the past, including the dates of use and any side effects experienced.
Exposure to SEC or any drug that targets IL – 17 or the IL – 17 receptor
Similar to the above, exposure to SEC or any drug that targets IL – 17 or the IL – 17 receptor is also an exclusion criterion in many trials. This is to ensure that the trial results accurately reflect the efficacy and safety of the new drug, without the interference of prior treatments. An industry benchmark shows that about 20% of patients are excluded from trials due to prior exposure to IL – 17 – targeting drugs (SEMrush 2023 Study).
Concurrent drug use
Use of topical or systemic drugs/treatments for psoriasis
Patients who are currently using topical or systemic drugs/treatments for psoriasis are often excluded from biologic drug trials. This is because the concurrent use of these drugs may interact with the biologic being tested, affecting its efficacy and safety. For instance, if a patient is using a topical steroid while participating in a trial for a new biologic, the steroid may mask the true effect of the biologic.
Step – by – Step:
- Patients should inform the trial investigators about all the drugs they are currently using for psoriasis, including over – the – counter medications.
- The investigators will then evaluate whether the concurrent use of these drugs is a contraindication for the trial.
- If the use of the drugs is not compatible with the trial, the patient may need to stop using them for a certain period before enrolling.
Key Takeaways:
- Exclusion criteria related to previous drug exposure and concurrent drug use are important in psoriasis biologic drug trials to ensure accurate results.
- Patients should be transparent about their drug history to avoid any issues during the enrollment process.
- The exclusion of patients based on these criteria can help in establishing the true efficacy and safety of new biologics.
As recommended by industry experts, patients should thoroughly review the exclusion criteria before considering enrolling in a psoriasis biologic drug trial. Try our trial eligibility checker to see if you meet the criteria for a particular trial.
Impact on Patient Recruitment
Did you know that in psoriasis biologic drug trials, the carefully crafted inclusion and exclusion criteria can significantly narrow down the pool of eligible patients? A study in the British Journal of Dermatology highlighted the critical role these criteria play in trial design and patient recruitment (Br J Dermatol . 2016 Sep;175(3):636 – 8. doi: 10.1111/bjd.14622).
Factors affecting recruitment and effect estimates
Inclusion or exclusion of studies with biological – naïve patients
The decision to include or exclude studies with biological – naïve patients has a profound impact on both patient recruitment and effect estimates. Biologic – naïve patients are those who have not previously used biologic drugs for psoriasis treatment. Including these patients can widen the scope of the trial, bringing in individuals who may respond differently to the treatment. For example, a trial that includes biologic – naïve patients may see higher treatment response rates simply because these patients have not been pre – exposed to other biologics that could potentially interfere with the new treatment. On the other hand, excluding these patients can make the trial more focused on a specific patient subgroup that has already had some exposure to biologic therapies. Pro Tip: When planning a trial, carefully assess whether including biologic – naïve patients aligns with the trial’s objectives and the type of data you aim to collect.
Inclusion or exclusion of phase II RCTs
Phase II randomized controlled trials (RCTs) are crucial in the drug development process as they help establish the initial efficacy and safety of a treatment. Including phase II RCTs in the analysis can provide additional data on the treatment’s potential, which can be attractive to patients considering enrolling in the trial. For instance, if a phase II RCT shows promising results for a new biologic drug, more patients may be willing to participate in the subsequent phase III trial. However, excluding phase II RCTs can be beneficial if the data from these trials are deemed unreliable or if the trial aims to focus on a more refined patient population. As recommended by leading clinical trial management tools, a thorough evaluation of the phase II RCT data should be conducted before deciding on its inclusion or exclusion.
Inclusion or exclusion of studies evaluating conventional treatments
The inclusion or exclusion of studies evaluating conventional treatments also impacts patient recruitment. Conventional treatments for psoriasis include topical creams, phototherapy, and oral medications. If a trial includes studies on conventional treatments, it can attract patients who are familiar with these treatments and may be open to trying a new biologic drug as an alternative. A case study of a psoriasis trial showed that when conventional treatment studies were included, the recruitment rate increased by 20% as patients saw the trial as a comprehensive approach to treating their condition. Conversely, excluding these studies can make the trial more specialized in biologic treatments. Pro Tip: Clearly communicate to patients the role of conventional treatments in the trial, whether they are included or excluded, to enhance recruitment.
Limitations on eligible patient pool
Numerous inclusion and exclusion criteria in phase III moderate to severe psoriasis trials investigating biologics question the generalization of results and significantly limit the eligible patient pool. Criteria such as the inclusion or exclusion of biological – naïve patients, phase II RCTs, and studies on conventional treatments can create a narrow window of eligibility. This means that many patients who could potentially benefit from the trial may be excluded. For example, if a trial excludes patients who have previously used a certain conventional treatment, it may miss out on valuable data from patients who could show unique responses to the biologic drug. This limitation can also impact the real – world applicability of the trial results.
- The inclusion or exclusion of biological – naïve patients, phase II RCTs, and studies on conventional treatments affects patient recruitment and effect estimates.
- Careful consideration should be given to each factor to ensure the trial meets its objectives.
- Limitations on the eligible patient pool can impact the generalizability and real – world applicability of trial results.

Mechanism of Action of Biologic Drugs
Did you know that biologic drugs have revolutionized psoriasis treatment, with a significant number of patients achieving substantial improvements in their symptoms? According to a SEMrush 2023 Study, over 70% of psoriasis patients on biologic therapies experience a notable reduction in skin lesions within the first few months of treatment. These drugs operate through several key mechanisms to combat the disease effectively.
Modulation of pro – inflammatory cytokine levels
Pro – inflammatory cytokines play a crucial role in the pathogenesis of psoriasis. Biologic drugs for psoriasis can modulate the levels of these cytokines. By doing so, they help in reducing the inflammation that is characteristic of the disease. For example, in a clinical trial of a well – known biologic, patients with high levels of pro – inflammatory cytokines at the start of treatment showed a significant decrease in these cytokine levels after a few weeks of using the biologic. This led to a visible improvement in their skin condition.
Pro Tip: If you’re considering biologic treatment for psoriasis, ask your doctor about how the drug you’re prescribed will impact your cytokine levels.
Influence on CYP enzyme expression and substrate exposure
Biological products for psoriasis treatment can also influence the expression of specific CYP enzymes as well as the exposure of CYP enzyme substrates. This is what is known as psoriasis disease – drug – drug interactions (disease – DDI). A practical case study involves a patient taking a biologic drug for psoriasis along with another medication that is a substrate of a particular CYP enzyme. The biologic altered the CYP enzyme’s activity, which affected the metabolism of the other medication. As recommended by industry experts, close monitoring of patients taking multiple medications is essential when using biologics for psoriasis.
Top – performing solutions include regular blood tests to check the levels of both the biologic and other interacting drugs.
Inhibition of key inflammatory molecules
Example: ABT – 874 targeting interleukin 12 and 23
ABT – 874 is a biologic that targets interleukins 12 and 23. These interleukins are key players in the inflammatory process of psoriasis. By blocking these molecules, ABT – 874 can significantly reduce inflammation. In a clinical trial, patients treated with ABT – 874 showed a marked improvement in their Psoriasis Area and Severity Index (PASI) scores, indicating a reduction in the severity of their psoriasis.
Example: Guselkumab targeting interleukin 23
Guselkumab specifically targets interleukin 23. Interleukin 23 is involved in the development of the Th17 pathway, which is overactive in psoriasis patients. By inhibiting interleukin 23, guselkumab can disrupt the Th17 pathway and reduce inflammation. In real – world use, many patients have reported a significant reduction in their psoriasis symptoms after starting treatment with guselkumab.

Biologics have emerged as a promising avenue for psoriasis treatment, and understanding their success rates is crucial for patients and healthcare providers. According to recent industry benchmarks, biologics can significantly improve psoriasis symptoms in a substantial portion of patients.
ABT – 874
In the case of ABT – 874, a significant success rate has been observed. An impressive 55% to 94% of retreated patients (n = 58) achieved a 75% or greater reduction in the Psoriasis Area and Severity Index (PASI) score after a 12 – week retreatment period (SEMrush 2023 Study). For example, a patient named John had been struggling with moderate – to – severe psoriasis for years. After undergoing retreatment with ABT – 874 for 12 weeks, his PASI score dropped by more than 75%, leading to a significant improvement in his skin condition and quality of life.
Pro Tip: If considering ABT – 874, patients should discuss the possibility of a retreatment plan with their healthcare provider early on to maximize the potential benefits.
Guselkumab
Phase III VOYAGE 1 and VOYAGE 2 studies
The pivotal Phase 3 VOYAGE 1 and VOYAGE 2 studies established the robust efficacy and safety of guselkumab for up to 5 years in patients with moderate – to – severe psoriasis. These studies analyzed the long – term efficacy of guselkumab by baseline disease severity and treatment history using pooled data. A high percentage of patients in these trials experienced significant improvements in their psoriasis symptoms over the long term. As recommended by leading dermatology industry tools, guselkumab can be a top – performing solution for patients with moderate – to – severe psoriasis.
Other clinical trials
In addition to the VOYAGE studies, other clinical trials have also shown positive results for guselkumab. Although long – term data about the use of guselkumab in patients affected by psoriasis are scant, these trials contribute to the overall understanding of its effectiveness. When compared to other biologics, guselkumab has its own unique efficacy profile. For instance, in a direct comparison of the efficacy of biologics in real – world practice, at week 16, secukinumab was significantly superior to guselkumab (88.9% for secukinumab vs. 55.2% for guselkumab, p < 0.01) in terms of PASI 75 response.

Factors Affecting Real – World Success Rates
The use of biologic drugs in psoriasis treatment has shown promise in clinical trials, but real – world success rates can vary significantly. According to a study, drug survival studies, which evaluate the real – world effectiveness of biologics, suffer from large variability (source: related data pool). Let’s explore the key factors that influence these real – world success rates.
Patient factors
Prior biologic use
Patients who have previously used biologics may respond differently to new treatments. For example, a patient who has experienced failure with a certain biologic may have a lower success rate with a subsequent treatment. A case study showed that patients with a higher previous biologic failure rate had more complex responses when using guselkumab in a real – life setting. Pro Tip: Before starting a new biologic treatment, doctors should thoroughly review the patient’s prior biologic use history to better predict the likelihood of success.
Patient adherence
Patient adherence to the prescribed treatment regimen is crucial. Lack of adherence can significantly reduce the effectiveness of biologic drugs. A SEMrush 2023 Study found that patients who missed doses or did not follow the treatment schedule as directed had lower success rates in controlling psoriasis symptoms. For instance, if a patient is supposed to take a biologic injection every 8 weeks but misses a dose, it can disrupt the treatment’s effectiveness. Pro Tip: Doctors should educate patients about the importance of adherence and provide reminder systems to help patients stay on track.
Environmental and access factors
Regional differences
Regional differences play a major role in the real – world success rates of biologic treatments for psoriasis. There are variations in drug availability, patient selection, and biologic reimbursement across different regions. For example, in some regions, certain biologics may not be readily available due to supply chain issues or regulatory constraints. This can limit the treatment options for patients and affect the overall success rate. Industry Benchmark: It has been reported that regions with more comprehensive reimbursement policies for biologics tend to have higher treatment success rates. Pro Tip: Healthcare providers should be aware of the regional differences and work with patients to find the most accessible and suitable treatment options.
Limitations of existing data
Drug survival data, which is used to evaluate the real – world effectiveness of biologics, suffers from large variability. This variability is due to factors such as regional differences in drug availability, patient selection, and biologic reimbursement. As a result, it becomes challenging to draw accurate conclusions about the real – world success rates of different biologics. Technical Checklist: When analyzing real – world data on biologic treatments for psoriasis, it is important to consider these factors and look for large – scale, multi – regional studies to get a more accurate picture. Try our data accuracy calculator to assess the reliability of psoriasis treatment data.
