Biological Therapy Treatment For Psoriasis
There are many factors that could contribute to itchy skin allergic reactions, insect bites, or dryness. And, that dry feeling is often exacerbated by age. However, it could also be a sign of an underlying medical condition that causes skin inflammation, such as psoriasis.
Biological therapy can help relieve symptoms of psoriasis by suppressing the part of the immune system that causes this inflammation. It can also attack proteins that promote the growth of abnormal cells which is a root cause of the condition.
What Are Biological Treatments
In the strictest dictionary definition, a biological treatment or biologic drug would be any drug that is a biological product this is true for most drugs, as they are extracted from plants, animals, and fungi, or developed through bioengineering.
In actual use, the terms ‘biological treatment’ and biologic refers to bioengineered monoclonalantibodies. These are made by laboratory animals against a target antigen. The antibodies are monoclonal, meaning :
- They are clones of each other
- The entire clone set attaches to the same type of epitope on the target antigen.
What Are The Potential Side Effects Of Biologics And How Can Someone Manage Them
The main side effects that biologics can cause include infections and malignancies.
While reducing inflammation in the skin is good for psoriasis, blocking the immune system which defends the body from infections and combats cancerous cells can potentially lead to adverse effects.
If the immune system does not protect the body from infections and cannot recognize and fight off abnormal cells as well as usual, a person may have a greater risk of infections and malignancies.
Besides these risks, TNF blockers have been associated with the development of multiple sclerosis, or MS.
Also, IL-17 blockers have an additional warning about a potential increased risk of inflammatory bowel disease, or IBD.
While the potential adverse effects may be worrisome, they are extremely rare. With regular follow-up visits to a dermatologist, these drugs are safe to use.
The dermatologist will examine the persons skin, assess their medical history for any potentially concerning symptoms, and perform blood monitoring.

When Are Biological Treatments Used
Biological treatments are used to treat severe and refractory cases of autoimmune diseases. Biological treatments are very effective, but because of their expense, they are typically reserved for patients who have failed at least three other treatments.
Skin diseases that can be treated with biological treatments
Patients Treated With Anti
Looking at primary outcome of the 376 patients treated with anti-TNF, 294 were responders, 30 were secondary nonresponders and 52 were primary nonresponders . Statistically fewer females than males responded when treated with anti-TNF . Regarding secondary outcome, among patients treated with anti-TNF, 250 had PASI scores available at baseline and after 3 months. Of these, 163 were good responders, 41 were intermediate responders and 46 were nonresponders . Previous treatment with ustekinumab was associated with nonresponse .

Modification And Transitioning Of Therapies
Novel optimization strategies can provide a standardized basis for the development of patient treatment, ensuring that the most beneficial outcomes can be reached. The modification of treatment is crucial to achieving the treatment goal following initial failure. The transitioning of treatments may take a number of forms, including direct switching to a new therapy and the overlap or temporary/permanent addition of a new therapy. The successful transitioning from methotrexate to biologic therapy has been demonstrated in other clinical trials.,
Efficacy may also be achieved with the use of concomitant therapy. Topicals such as corticosteroids, calcipotriene and other agents may be used as monotherapy or combination therapy in psoriasis treatment. Topical therapy is usually the initial therapy used in psoriasis treatment and can be added to biologic therapies to optimize results. Acitretin is a retinoid that may be combined with biologic agents to increase efficacy and reduce side-effects compared with retinoid monotherapy, including a possible reduction in the risk of skin cancer.,
Biologics Are Expensive But You Likely Wont Pay All Of It Out Of Pocket
Biologics can cost between $10,000 and $30,000 per year, and potentially up to $500,000 for the most expensive options. Most insurance companies cover at least a portion of that, but how much youll pay out of pocket and which drugs are covered depends on your insurance plan.
If you cannot afford the biologic youre prescribed, talk to your doctor or pharmacist about your options. Your state may have a drug plan to assist with medication costs. You can also check the drug manufacturers website for their patient assistance program : You might qualify for lower co-pays or even be able to get the medication free.

Polymorphisms Associated With Ustekinumab Treatment
We then evaluated associations between SNPs and response to ustekinumab therapy using drug survival as outcome, comparing genotypes of responders with those of primary nonresponders. Five of the analyzed SNPs showed nominal statistical significance for both crude and adjusted ORs , none of which remained significant after controlling for FDR. Next, associations of each SNP and response to ustekinumab therapy were evaluated using PASI reduction as outcome, comparing genotypes of good responders with those of nonresponders under a dominant model. Six of the analyzed SNPs showed nominal statistical significance for both crude and adjusted ORs . Four associations remained significant after controlling for FDR, the variant alleles of TIRAP and TLR5 were associated with beneficial response and the variant alleles of IL1B and IL1B were associated with nonresponse .
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.

Why Do Dermatologists Prescribe A Biologic To Treat Psoriasis
A biologic is an important treatment option for people with moderate-to-severe psoriasis, psoriatic arthritis, or both. For many people, taking a biologic was life changing because it helped control their symptoms when other treatments failed.
Benefits of biologics
Using a biologic to treat psoriasis is life changing for some people.
Biologics work by blocking reactions in your body that cause psoriasis and its symptoms.If you have psoriatic arthritis, a biologic can stop the pain, stiffness, and swelling in your joints. It can prevent the arthritis from worsening and causing more damage to your joints. The US Food and Drug Administration has approved the following biologics to treat adults with psoriasis or psoriatic arthritis. In many cases, these biologics have been approved to treat both diseases.
1Approved to treat adults when other psoriasis treatments fail to work or stop working.
Sometimes, a biologic is prescribed to treat a child who has psoriasis. This can be very effective for a child who has severe psoriasis. The FDA has approved usetekinumab to treat people 12 years of age and older who have moderate-to-severe psoriasis.
What Should People Know About Self
A person can self-inject nearly every biologic on the market in the comfort of their own home. Many companies also provide nursing support, which involves a nurse visiting the persons home to teach them to self-administer injections.
Most of the medications are administered through auto-injector pens, rather than traditional syringes, to ease the process. In some cases, people can still go to their doctors office for the injections, if they are not comfortable administering them at home.
The first step is to thoroughly clean the hands and the site of the injection. An injection should only take place in an area that is not affected by psoriasis.
Place the auto-injector flush to the skin, then press the releaser to deliver the medication. Do not lift the auto-injector from the skin until the dose has been fully administered.
Then, clean the skin again if there is a drop of blood, and apply an adhesive bandage.

Can Biologics Be Combined With Other Treatments
The use of a single drug or a single therapy method may not work for everyone with psoriasis. If single drugs arent working for you, or arent working as well as they once did, it may be time to consider combining biologics with other treatments for psoriasis.
There are three main benefits of using a combination approach:
- It can decrease the possibility of reaching toxic levels with a single drug.
- The individual drugs can be prescribed at a lower dose.
- A combination approach can be more successful than a single treatment option.
How Severe Is Your Condition
Its easy to say that covering a certain percentage of the body makes psoriasis moderate or severe. Some professionals say 10% coverage is considered severe. However, poorly managed psoriasis on the hands, feet, or other sensitive areas can be just as painful, so your dermatologist will evaluate the severity of your symptoms on a case by case basis. If your psoriasis symptoms negatively impact or impede your ability to function, your condition is probably severe enough for biologic treatment.

Best Biologics For You
Immune system proteins called cytokines cause the swelling and scaly skin patches you get in psoriasis. Each group of biologic drugs blocks a different cytokine.
Everyone responds differently to these medicines, but some biologics seem to tamp down psoriasis better than others. One review of studies showed that drugs that block two specific proteins — interleukin-17 and -23 — cleared skin better than ones that inhibit a protein called TNF-alpha.

Observational Cohort Study Finds Less Risk Of Serious Infection In Patients Taking Newer Targeted Systemic Medications For Psoriasis
- Beth Israel Deaconess Medical Center
- 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.”

Psoriasis Treatment With Biologics: 5 Things To Know
Caitlin G. Purvis Steven R. Feldman, MD, PhD
Psoriasis affects at least 100 million people worldwide, with plaque psoriasis being the most common form. Although many different medication options are available for psoriasis, the type of treatment prescribed is chosen on the basis of severity and percentage of body surface area affected . Moderate psoriasis involves 3%-10% of the BSA, while severe psoriasis involves greater than 10%. For moderate to severe psoriasis, the American Academy of Dermatology and National Psoriasis Foundation Guidelines recommend systemic treatments, including biologic agents.
The development of several biologic agents over the past decade has dramatically changed the treatment landscape for patients with psoriasis. Biologic agents are engineered monoclonal antibodies and fusion proteins that block the specific cytokines or their receptors that mediate the inflammation seen with psoriasis. To date, 11 biologic agents are approved by the US Food and Drug Administration for psoriasis. A recent meta-analysis of treatments for moderate to severe psoriasis suggests that biologics have a superior response rate compared with other treatments . Because adequate head-to-head comparison data are limited, determining which treatment option is best for your patients can be challenging.
Here are five things to know about treatment of psoriasis with biologics.
How Safe Are The Drugs
Most of what is known about side effects of the biologics comes from trials of people with rheumatoid arthritis, Crohns disease, or other ailments. The risk of experiencing a side effect for people with psoriasis appears to be less because combination therapy with methotrexate and other medications that suppress the immune system were not used in psoriasis clinical trials.
The risk of experiencing side effects is an important factor to consider when choosing to take a biologic drug.

Treatment Of Associated Conditions
Health conditions associated with psoriasis include psoriatic arthritis, sleep disturbance, and depression. Treatment for these may help skin disease.
Due to the association between psoriasis and metabolic syndrome, weight loss, smokingcessation, moderation of alcohol intake, and blood pressure control may also lead to improvements in skin disease .
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.

Relationship Between Biosimilars And Biologics
Biosimilars are highly similar to their biologic reference product. All biologics, including biosimilars:
- Target specific parts of the immune system rather than impacting the entire immune system
- Are given as an injection or IV infusion
To be approved as a biosimilar for a particular reference biologic, the biosimilar must be:
- Highly similar to the reference product and cannot have any clinically meaningful differences in terms of safety or efficacy
- Approved for the indication and condition for which the reference product is approved
- Be given the same form and in the same dosage as the reference product
- The same mechanism of action as the reference product, which means it works the same way in the body
An interchangeable biosimilar must meet the biosimilar standard plus an additional standard that the treatment will produce the same clinical result as the reference product in any given patient. If a biosimilar is approved as interchangeable, a pharmacist may substitute it without letting your prescribing health care provider know, in some states.
Keep in mind that biosimilars are not exact copies of their biologic reference product. Biologics are large and complex molecules from living sources that cannot be exactly copied.
Many considerations go into a treatment decision. Always speak with your health care provider about the potential risks and benefits of a treatment recommendation.
How Well Do Biologics Work
Biologics don’t cure psoriasis, but theyâre effective. Some people see clearer skin within a few weeks.
These drugs may be the best option if your symptoms are moderate to severe. Biologics work better than conventional drugs like methotrexate, acitretin , and cyclosporine . And their targeted actions can mean fewer side effects.
Some biologics work better the longer you’re on them, or if you pair them with another psoriasis treatment. But not everyone sees big benefits. Others canât tolerate the side effects, which can include a skin reaction to the shot, diarrhea, and headaches.
