How Do Biologics Work In The Body To Relieve Psoriasis Symptoms
We know that psoriasis is caused by overactivity of the immune system with resulting skin inflammation.
Without inflammation, the skin can return to its original healthy state, but joint damage can be permanent. This is why it is so important to receive a diagnosis and start treatment as early in the course of the disease as possible.

What Are The Risks Of Biosimilars
The risks and side effects of biosimilars are the same as those associated with their biologic reference product. Anyone considering taking a biosimilar should talk with their health care provider about the short- and long-term side effects and risks. It is important to weigh the risks against the benefits.
Biologics and biosimilars act on cytokines, which are specific proteins released by the immune system that can cause inflammation. Biologics suppress the function of the overactive immune system. When on a biologic or biosimilar, you may have a higher risk of infection. If you develop any signs of an infection, contact your health care provider right away.
Signs of infection include:
- Damp, sticky feeling or sweating
- Fever

The Safety And Side Effects Of Biologics
Although biologics cannot cure psoriasis, many people taking these drugs are getting good results with few side effects. However, because biologics change the way your immune system works, there are possible risks. Also, doctors do not yet know all the long-term effects of taking them.
Known risks of taking a biologic drug include:
-
Infections. Biologics may decrease your ability to fight off an infection or may allow an old infection to reactivate. Your doctor will ask you about any history of infection and may test to see if you have been exposed to . Before starting a biologic, you may need to be vaccinated against some infectious diseases.
-
Medication reactions. You may get after taking a biologic, such as fever, , and . Reactions can take place at the site of the injection, including swelling, itching and .
-
Nervous system disorders. These are rare but can include , , and vision problems.
-
and other cancers. This risk is very small, but it’s one of the reasons that these drugs are not approved for children.
What Is Systemic Treatment For Psoriasis
You may have heard your provider talk about systemic psoriasis treatment, as opposed to treating with topicals or light therapy. Systemic therapy means that the treatment gets where it needs to go through systemic circulation throughout the body, as opposed to putting a cream or a light directly on the affected area. In the case of psoriasis treatment, systemic therapies include oral treatments, injectables, and IV infusions, according to the National Psoriasis Foundation.4

Subgroup Analysis On Biologic
The subgroup analysis limited to biologic-naïve subjects is illustrated in Fig. , with the forest plots shown in Supplementary Fig. . There were 7 studies reporting data on biologic-naïve patients for etanercept, 7 studies for adalimumab, 4 studies for infliximab, and 4 studies for ustekinumab. The drug survival in biologic-naïve patients was generally higher than that in all subjects. The drug survival in biologic-naïve subjects gradually decreased with time for all biologics, too. The drug survival rate fell from 0.67 at year 1 to 0.52 at year 4 for etanercept, from 0.67 to 0.63 for adalimumab, from 0.57 to 0.47 for infliximab, and from 0.88 to 0.87 for ustekinumab. Ustekinumab had a trough drug survival at year 3 because the study of Mitratza et al.. Contributed data to the low survival at year 3. In general, ustekinumab was associated with the highest drug survival rate and infliximab associated with the lowest rate in biologic-naïve subjects.
What Are Biologics And How Are They Different From Other Treatments For Psoriasis
Biologics are medications that are either made from living cells in a lab or through a biological process. This is how they get their name. Traditional drugs, on the other hand, are small molecules created in a lab.
Biologics target specific parts of the immune system. They treat diseases by modulating activity of specific immune cells or inflammatory messengers called cytokines.
Since biologics are so targeted, they can also be safer than medications that broadly suppress the immune system.
As we continue to gain knowledge about the specific causes of diseases such as psoriasis, better and safer biologics will continue to come onto the market.
Four classes of biologics are currently available:
- blockers of tumor necrosis factor-alpha
- interleukin 12 and 23 inhibitors
- IL-17 inhibitors
- IL-23 inhibitors
Each of these molecules are specific messengers in the immune system involved in the development of psoriasis. The dosing regimen and side effects differ, depending on the drug.
TNF-alpha blockers include adalimumab , etanercept , and certolizumab pegol .
They are all approved to treat both psoriasis and psoriatic arthritis. Depending on the drug, people will need a dose every week or every other week.
Also, these biologics are the most broad-acting medications, as TNF-alpha is an upstream mediator of inflammation. The further downstream the target, the more specific the biologic is, and potentially the fewer side effects it has.

Usage With Psoriasis Treatments
In addition to DMARDs like methotrexate, current biologics can be used in conjunction with these psoriasis therapies:
Topical treatments, whichare applied directly to the skin and are a first-line treatment for psoriasis. They slow down or normalize excessive skin cell growth and reduce skin inflammation.
, also called light therapy, which exposes skin to ultraviolent light under medical supervision. Exposure needs to be consistent to penetrate skin and slow skin cell growth. Phototherapy may, however, increased the risk of skin cancer if a person is taking TNF-inhibitors or vice versa. This is because photosensitivity is a side of effect of these medications.
How Biologics Can Treat Psoriasis
Biologics may also be used to block certain proteins that can trigger psoriasis development. Psoriasis can be caused by the overstimulation of the TNF-alpha protein , therefore the biologic known as the TNF-alpha inhibitor can work to stop the overproduction of this protein in the body. Two other types of proteins are also linked with psoriasis , and both of these proteins have specific biologic inhibitors that can deactivate these proteins in the body.

Will Any New Biologics Being Developed Get Us Closer To A Cure For Psoriasis
While researchers are currently evaluating new biologics, it will be several years before they become available.
The good news is that the options available are providing safe and effective results. We can confidently say that the current medications can lead to 90100% clearance of symptoms in people with psoriasis.

Other Types Of Biologics
Biologics refer to any type of medical treatment that is derived from living organisms. They can include a wide variety of therapeutic options such as blood platelets, hormones, vaccines, and stem cells. Generally, biologic medications for treating autoimmune conditions involve using antibodies to directly target autoimmune processes to decrease inflammation.

How To Take And Store
Your biologic medication should be refrigerated before use. Remove your medication 30 minutes before the time that you are going to administer your injection so that the medication can reach room temperature.
Before you administer your injection, you should have an alcohol pad and sterile bandage ready. Wash your hands with soap and water, and swab the skin where you will administer the injection with an alcohol pad to cleanse the skin and reduce the risk of infection.
The frequency of injections depends on the specific type of medication that you are prescribed. Remicade is delivered intravenously through insertion of an IV into a vein and repeated every eight weeks.
All the other types of biologic medications are injected subcutaneously, or under the skin, most commonly in your abdomen or thigh. Some medications require a frequent injection schedule, such as Enbrel every week and Humira, Siliq, and Cimzia every other week.
Other medications require less frequent injections after the initial dose, such as Cosentyx and Taltz every four weeks, Simponi once a month, Tremfya every eight weeks, and Skyrizi and Stelara every 12 weeks.
It is important to follow your dosing regimen as missed doses can reduce the effectiveness of your biologic medication.
Traditional Treatments Arent Working
Traditional treatment options for psoriasis include topical creams, corticosteroids, cyclosporine, retinoids, methotrexate, and phototherapy. People with mild to moderate psoriasis can usually manage their disease well with topical treatments. But these treatments often dont work well enough for those with moderate to severe cases. Some treatments may also lose effectiveness over time.
If you have moderate to severe psoriasis and your current treatment regimen isnt working, its time to start considering a biologic. The American Academy of Dermatology suggests taking a biologic agent if you have moderate to severe psoriasis that hasnt improved using more traditional systemic agents or you cant tolerate those treatments because of side effects.

Observational Cohort Study Finds Less Risk Of Serious Infection In Patients Taking Newer Targeted Systemic Medications For Psoriasis
- Date:
- Beth Israel Deaconess Medical Center
- Summary:
- Dermatologists found a decreased risk of infection in patients with psoriasis using some of the newer, more targeted medications compared to those taking methotrexate, a drug widely used since the 1960s as a first line treatment for moderate-to-severe psoriasis.
A common chronic skin condition affecting 125 million people worldwide, psoriasis is an autoimmune disease, a class of disorders in which the immune system attacks the body’s own healthy cells. In recent years, new medications — known as biologics — that inhibit the overactive immune system by targeting specific inflammatory pathways, have revolutionized the treatment of psoriasis and other autoimmune diseases. However, until now, few studies have documented the comparative safety of these various biologics.
“In addition to being potentially more effective than methotrexate, some of the newer targeted treatments for psoriasis may also be safer for patients in terms of risk of infection,” said Dommasch, who is also Instructor of Dermatology, Harvard Medical School. “Doctors and patients may want to consider the risks of infection when choosing a systemic treatment for patients with moderate to severe psoriasis.”
“This information should be considered when prescribing therapies for individual patients,” said Dommasch. “This study demonstrates how researchers can use ‘big data’ to help compare the safety of different medications for patients with psoriasis.”
Relation To Prior Literature
Biologicals have become potent and effective therapeutic alternative for many inflammatory and autoimmune diseases like RA and PsA, focus of this cohort population. Their direct and focused effect makes them superior to classic immunosuppressive, whose use is frequently limited by undesirable and often severe generalized adverse effect. Biologic agents targeting specific immune mediators have emerged as other treatment option for patients with RA, PsA and others immune disease who are unresponsive to, or intolerant of, non-biologic systemic agents. .
Furthermore, conventional treatments for PsA have limited efficacy for nail disease, enthesitis or axial involvement, and some are unable to control moderate and severe peripheral joint and skin disease . The introduction of biologic treatments offered the possibility of controlling multiple aspects of these diseases using a single drug, minimizing the need for additional therapies .
Although several biologics have demonstrated good efficacy and tolerability in short-term trials, treatment guidelines recommend them as third line therapies due to a relative lack of long-term safety data. Here, we have reviewed the long-term safety data. In our study, 35% of patients used biological agents for more than 37 months, reflecting the real scenario of its long-term use in Brazil.
Serious infections were uncommon in population currently using the biological agents for more than six months.

If your psoriasis is severe or other treatments have not worked, you may be prescribed systemic treatments by a specialist. Systemic treatments work throughout the entire body.
These medications can be very effective in treating psoriasis, but they all have potentially serious side effects. All the systemic treatments for psoriasis have benefits and risks. Before starting treatment, talk to your doctor about your treatment options and any risks associated with them.
If you’re planning for a baby, become pregnant or are thinking of breastfeeding, you should also speak to your doctor first before taking any new medicine to check it’s suitable for use during pregnancy or breastfeeding.
There are 2 main types of systemic treatment, called non-biological and biological .
Biologic Treatment Of Psoriatic Disease
Many different biologic drugs have been approved by the U.S. Food and Drug Administration for treating moderate to severe psoriatic disease. They are not considered a first-line treatment because of their cost and side effects.
While biologics are usually prescribed with a DMARD, they can also be prescribed alone. When a person with disease starts taking a biologic drug, they will also remain on their current treatment plan, which may include non-steroidal anti-inflammatory drugs , corticosteroids, and/or DMARDs.

Infusion Therapy Treatment For Psoriasis
Psoriasis is a common, chronic skin disease that causes itchy, scaly, red patches to develop throughout the body, often appearing on the scalp, elbows, and knees. Though the cause of psoriasis is not totally understood at present, the immune system and genetics both contribute to its onset. People with psoriasis generally experience flare-ups due to triggers such as stress, skin injury, medications, excessive consumption of alcohol, and infections. While psoriasis can make life very uncomfortable, infusion therapy can disrupt the inflammation cycle of the disease and provide a high degree of relief.

Background: Biological agents used for the treatment of psoriatic arthritis and rheumatoid arthritis are associated with serious adverse effects . Although several biologics have demonstrated good efficacy and tolerability in short-term trials, treatment guidelines recommend them as third line therapies due to a relative lack of long-term safety data.
Objective: To determine the frequency and severity of adverse effects associated with the long-term use of biologics in the treatment of PsA and RA, and possible risk factors for such events in a real-life setting.
Methods: We conducted a longitudinal study in PsA and RA patients only taking long-term biological agents from 2003 to 2011. Sources of information included dispensing pharmacy data and interviews with patients. Research staff conducted telephone interviews with patients inquiring about any apparent medication-related adverse drug reactions or SAEs. ADR/SAEs data was based on pharmacy reports. We conducted a multivariate analysis to identify the factors associated with the risk of ADRs.

Who Can Take Biosimilars
All biologics, including biosmilars, are typically prescribed for people with more advanced disease, including individuals with moderate-to-severe psoriasis and active PsA. But each of the three approved biosimilars are indicated for different groups within this population.
You should not take biosimilars if:
- Your immune system is significantly compromised
- You have an active infection
Screening for tuberculosis or other infectious diseases is required before starting treatment with all biologics, including biosimilars.
How We Reported This Story
In order to examine the adverse events associated with biologic drugs used to treat autoimmune diseases of the skin , joints and the gastrointestinal system, the Milwaukee Journal Sentinel relied on two databases: The U.S. Food and Drug Administrations adverse events reporting system and a database of the autoimmune drug market supplied by IQVIA, a pharmaceutical market research firm.
The FDAs adverse events database is the largest publicly available data set that records reactions associated with prescriptions drugs. In recent years, the number of reports submitted to the agency has risen dramatically researchers, as well as the FDA itself, are increasingly using the data to detect potential problems.
The database has several limitations. While drug manufacturers are required to submit reports of adverse events to the agency, reports that come from medical professionals or consumers are voluntary. There is widespread agreement these reports are an undercounting of adverse events associated with prescription drugs. In part because of the voluntary nature of the reports, this data cannot be used in isolation to determine the incidence rates of certain outcomes or reactions or to establish a causal relationship between a drug and a reaction.
Two drugs that also are approved to treat autoimmune diseases, Rituxan for rheumatoid arthritis and Tysabri for Crohns disease, were not included in the adverse events numbers because they were not on the IQVIA list.

Types Of Biologics That May Help
There are many types of biologics for those suffering from psoriasis and psoriatic arthritis to try. As stated, some biologics will target different proteins or T cells, and not every biologic works for everyone. Other types of biologics for those who suffer from psoriasis:
- Cimzia
- Simponi
- Stelara
Its important to check if the biologic you are looking to use is able to be used with any other medications you are using. Some biologics can be used in conjunction with other medications you are using for psoriasis, such as topical ointments or
