Nielsen Biosciences Announces Enrollment of First Patient in Phase 3 Trial of CANDIN for the Treatment of Common Warts

The study represents a potential breakthrough in the treatment of common warts

Nielsen BioSciences, Inc. (“Nielsen”), a privately-held, San Diego-based biopharmaceutical company, today announced the first patient enrolled in CFW-3A –  a Phase 3, randomized, double-blind, placebo-controlled study of the safety and efficacy of CANDIN® for the treatment of Verruca vulgaris (common warts) in adolescents and adults. The study is ongoing and will continue to enroll patients across sites in the U.S. and Japan, making this Nielsen’s first clinical study with global reach. Nielsen is partnering with Maruho Co. Ltd. (“Maruho”) in the clinical development program for CANDIN. Maruho is also planning to commercialize CANDIN in Japan.

“The first patient treated with CANDIN represents a major milestone for the company, and for patients affected by common warts around the world,” said David P. Burney, PhD, MBA, President and Chief Operating Officer at Nielsen BioSciences. “We are proud of this new phase in our continuous effort to develop this new therapy and make it available to a patient population with high unmet need.”

Verruca vulgaris are benign lesions caused by infection of the skin with the human papillomavirus (HPV). They are raised lesions on the skin, commonly on the fingers, palms, knees, and soles of the feet. Since warts are caused by a viral infection, skin symptoms can be widespread and refractory. Common warts are estimated to affect approximately 10 percent of the global population.1 There are currently no FDA-approved prescription treatments.

“We are in dire need of new therapies for wart treatment. I am excited about this trial and the potential to provide patients with an alternative to standard wart removal via acid, surgery, cryotherapy and other methods that can damage skin,” said Sandra Johnson, MD, FAAD, Dermatologist from Fort Smith Arkansas and one of the principal investigators of this clinical trial.

 

About the Study

The study is a phase 3, randomized, double-blind, placebo-controlled study of the safety and efficacy of CANDIN (Candida albicans Skin Test Antigen for Cellular Hypersensitivity) for the treatment of common warts (Verruca vulgaris) in adolescents and adults. The goal of the clinical trial is to compare outcome in healthy subjects 12 years of age and older with at least 3, but no more than 20, common warts (Verruca vulgaris) following treatment with CANDIN or placebo. For more information, please see the study details at ClinicalTrials.gov.

Nielsen BioSciences’ SPHERUSOL® Valley Fever Test Incorporated into Medicare Payment for Coccidioidomycosis Skin Test

/PRNewswire/ — Nielsen BioSciences announced today that the Centers for Medicare & Medicaid Services (CMS) updated the payment rate for the coccidioidomycosis skin test to recognize the cost of SPHERUSOL® (Coccidioides immitis Spherule-Derived Skin Test Antigen).  The skin test is used in patients with Valley Fever.

“CMS’ decision to update the reimbursement rate for the coccidioidomycosis skin test will support access to the critical information SPHERUSOL provides to help manage this devastating disease, Valley Fever,” said Tom Carpenter, DVM, Ph.D., president and chief operating officer of Nielsen BioSciences. “SPHERUSOL can aid physician assessments about how the patient’s immune system is fighting the disease, information that they otherwise would not be able to attain from other commercially available tests for Valley Fever. We are pleased to see the decision by CMS, which will enable physicians to get appropriate reimbursement when testing patients impacted by this serious disease.”

Valley Fever is a serious infection that usually affects the lungs and is caused by inhaling airborne spores of the Coccidioides fungus, which grows in dry desert soil of the western United States. According to the Centers for Disease Control and Prevention, of the estimated 150,000 people per year who become infected with the Valley Fever fungus, 40 percent will develop symptoms, including fever, cough, chest pain, headaches, weight loss, night sweats, lethargy, and/or rashes. In severe cases, the fungal infection spreads from the lungs to other parts of the body, such as the central nervous system (brain and spinal cord infection), skin, bones and joints, can have life-long consequences and be life-threatening.

CMS’ updated reimbursement rate for the coccidioidomycosis skin test is $70.58 per test under the CMS Medicare Physician Fee Schedule for 2016. The updated reimbursement rate went into effect at the beginning of January. The Medicare reimbursement rate is also an importance source of information that may be used by private insurers and state health care plans to determine their own rate of reimbursement.

About SPHERUSOL


SPHERUSOL is a skin test antigen administered by heath care professionals and is indicated for the detection of delayed-type hypersensitivity to Coccidioides in individuals with a history of pulmonary coccidioidomycosis. SPHERUSOL is a commercially available test specifically designed to see if a patient’s cellular immune system is responding to the fungus (Coccidioides) that causes Valley Fever.

The safety and effectiveness of SPHERUSOL have not been established in pregnant and nursing women, the pediatric population, or individuals > 65 years of age. The use of SPHERUSOL to detect delayed-type hypersensitivity response in a general population with unknown exposure to Coccidioides has not been evaluated. Persons with acute or disseminated coccidioidomycosis may not develop a delayed-type hypersensitivity response to SPHERUSOL. Persons with immunodeficiency and a history of coccidioidomycosis may not develop a delayed-type hypersensitivity response to SPHERUSOL.

 

Boxed Warning

The expected response to SPHERUSOL is a local area of inflammation at the site of the skin test. The reaction is usually dime to quarter size reaching maximum diameter between 24 and 48 hours. Larger accelerated reactions can occur, which may require treatment with local cold compresses and anti-inflammatory medication. Systemic reactions can occur with skin test antigens and in certain individuals these reactions may be life-threatening or cause death. Emergency measures and personnel trained in their use should be immediately available. Patients should be observed for at least 20 minutes following the administration of a skin test. SPHERUSOL should never be given intravenously. 

 

Additional Safety Information

The most common side effects in clinical studies were itching, swelling, pain and ulceration at the site. Certain drugs that suppress the immune system, such as corticosteroids, can prevent a delayed-type hypersensitivity response to SPHERUSOL.

See www.nielsenbiosciences.com for full prescribing information.

 

About Nielsen BioSciences 

Nielsen BioSciences develops products to help in the evaluation, treatment, or prevention of immune-mediated diseases that can be missed by narrowly targeted diagnostic strategies. In addition to SPHERUSOL, Nielsen markets CANDIN® (Candida albicans skin test antigen for cellular immunity.) FDA-approved for detecting delayed-type hypersensitivity, CANDIN is also a drug candidate in ongoing investigational studies evaluating its use in the treatment of human papilloma virus (HPV) lesions.

Nielsen BioSciences’ SPHERUSOL Provides Physicians with New Test for Valley Fever

Nielsen BioSciences announced today the launch of SPHERUSOL® (Coccidioides immitis Spherule-Derived Skin Test Antigen), a skin test that provides valuable data to physicians managing Valley Fever infections. SPHERUSOL has been approved by the U.S. Food and Drug Administration as the only skin test to detect an immune response to the fungus called Coccidioides, or “cocci,” in patients with history of the disease. Valley Fever is a serious infection that usually affects the lungs and is caused by inhaling airborne spores of the cocci fungus, which grows in dry desert soil of the western United States from Washington to Texas, with the bulk of cases occurring in Arizona and California. Until now, tests available to physicians for Valley Fever have been limited to blood tests, X-rays, cultures and biopsies, none of which provide information about the cellular immune response, which is comprised of disease-fighting cells responsible for overcoming the disease.

“SPHERUSOL fills critical gaps in the current testing of Valley Fever,” explained Tom Carpenter,  DVM, Ph.D., senior vice president and chief development officer of Nielsen BioSciences. “With SPHERUSOL now broadly available, physicians have access to an important new tool to further inform their treatment decisions and incorporate into their standard of care of patients with this fungal disease.” Of the estimated 150,000 people per year who become infected1 with the Valley Fever fungus, 40 percent will develop symptoms, including fever, cough, chest pain, headaches, night sweats, or rashes(2). Diagnosis is often delayed for months as symptoms can be confused with the flu or bacterial pneumonia. The average patient misses a month of work or school. In severe cases, the fungal infection spreads from the lungs to other parts of the body, such as the central nervous system (brain and spinal cord infection), skin, bones and joints, can have life-long consequences and be life-threatening3.

“The information SPHERUSOL provides is important for tracking patients’ active infections and is critical to determining the urgency of care required for each individual. Knowing a patient’s skin test status helps me in managing my patients with Valley Fever,” said pulmonologist and author Craig Rundbaken, D.O., F.A.C.O.I., F.C.C.P., founder of the Arizona Institute of Respiratory Medicine and Valley Fever Clinic, in Sun City West, AZ.

Introduction of a new test for Valley Fever was also noted by U.S. House Majority Leader Kevin McCarthy (R-CA) and U.S. House Representative David Schweikert (R-AZ), who serve as the co-chairs of the bipartisan Congressional Valley Fever Task Force and are from the two states where the disease is most prevalent.

“As new advancements are made, the fight against Valley Fever continues to move forward. We must continue to work to improve the way we treat and prevent this disease,” said Majority Leader McCarthy.

“Valley Fever has silently affected entire communities in the southwest, including our families, friends, and even our beloved pets,” said U.S. House of Representative David Schweikert. “I am honored to be working with both our local businesses and constituency to help expand our efforts.  I see new developments, such as the introduction of the Spherusol skin test, as vital steps forward in the fight against Valley Fever.”

While Valley Fever is viewed as a regional disease of the desert west, the impact on the lives and economies of the region is substantial. Nationally in 2013 as many people were reported diagnosed with Valley Fever as were with the better-known disease tuberculosis.(4)

 

About SPHERUSOL

SPHERUSOL is a skin test antigen indicated for the detection of delayed-type hypersensitivity to Coccidioides in individuals with a history of pulmonary coccidioidomycosis.

Until now, clinicians had no commercially available test to see if the patient’s cellular immune system is responding to the disease. Spherusol addresses this unmet need because it is specifically designed to test the response of these disease-fighting cells to Valley Fever.

The safety and effectiveness of SPHERUSOL have not been established in pregnant and nursing women, the pediatric population, or individuals > 65 years of age. The use of SPHERUSOL to detect delayed-type hypersensitivity response in a general population with unknown exposure to Coccidioides has not been evaluated. Persons with acute or disseminated coccidioidomycosis may not develop a delayed-type hypersensitivity response to SPHERUSOL. Persons with immunodeficiency and a history of coccidioidomycosis may not develop a delayed-type hypersensitivity response to
SPHERUSOL.

 

Boxed Warning

The expected response to SPHERUSOL is a local area of inflammation at the site of the skin test. The reaction is usually dime to quarter size reaching maximum diameter between 24 and 48 hours. Larger accelerated reactions can occur, which may require treatment with local cold compresses and anti- inflammatory medication.
Systemic reactions can occur with skin test antigens and in certain individuals these reactions may be life-threatening or cause death. Emergency measures and personnel trained in their use should be immediately available. Patients should be observed for at least 20 minutes following the administration of a skin test. SPHERUSOL should never be given intravenously.

 

Additional Safety Information

The most common side effects in clinical studies were itching, swelling, pain and ulceration at the site. Certain drugs that suppress the immune system, such as corticosteroids, can prevent a delayed-type hypersensitivity response to SPHERUSOL.
