Here is news from a potential competitor for Prurisol. The results of this small POC trial are good but the drug is intravenous.
Galectin Therapeutics Announces Positive Interim Results from Phase 2a Trial with GR-MD-02 in Moderate-to-Severe Plaque Psoriasis
A significant clearing of psoriasis in first four patients prompts the extension of treatment for an additional 12 weeks
Conference call to be held tomorrow at 9:00 a.m. Eastern time
NORCROSS, Ga., May 16, 2016 (GLOBE NEWSWIRE) -- Galectin Therapeutics Inc. (NASDAQ:GALT), the leading developer of therapeutics that target galectin proteins, announces positive interim results from an exploratory, open-label, Phase 2a clinical trial with GR-MD-02 in patients with moderate-to-severe plaque psoriasis. All four patients who received 12 weeks of therapy (six doses of GR-MD-02) had significant improvement in their plaque psoriasis. Given the improvement noted, Galectin has extended the treatment duration to 24 weeks.
This Phase 2a open-label trial is being conducted in 10 patients with moderate-to-severe plaque psoriasis who have ≥ 10% of their skin surface area affected and a PASI (Psoriasis Area and Severity Index) of ≥ 12 points. The enrolled patients are being treated with 8 mg/kg of GR-MD-02 every other week for a total of seven infusions, with the seventh infusion being administered on the same day the 12-week PASI is scored. The primary efficacy assessment in this study is improvement in PASI, as described in detail in a recent CEO Perspective.
"Each of the four patients who received six doses of GR-MD-02 over 12 weeks of therapy reported improvement in their symptoms related to psoriasis," said Simon A. Richie, M.D., Staff Dermatologist, Chief of Phototherapy and Tele-Dermatology at San Antonio Military Health System and Principal Investigator of the trial. "Moreover, all four patients had significant improvement in PASI measurements. It is uncommon for patients with moderate-to-severe plaque psoriasis to spontaneously improve without treatment. The drug infusions were well tolerated by patients, and the two adverse events that were noted, one infiltration of the intravenous catheter and one headache during infusion, were mild and transient."
Interim results are shown in the table below.

4 12.8 7.2 44 % 4.3 66 %
* PASI performed on same day as 7th infusion
** PASI performed 1 week following 7th infusion; patient taken off systemic therapy for psoriasis one month prior to starting therapy
"These interim results on four patients in this exploratory clinical trial demonstrate a potentially important clinical effect of GR-MD-02 in clearing moderate-to-severe plaque psoriasis," said Peter G. Traber, M.D., Galectin's president, chief executive officer and chief medical officer. "While these patients were not evaluated for fatty liver disease, these findings may have implications for activity in our main therapeutic program targeting NASH, a disease where there is a high incidence of psoriasis and increased galectin-3 in the skin. We are excited to extend this trial to better determine the full potential of GR-MD-02 as a treatment for moderate-to-severe psoriasis."
The link, if any, between non-alcoholic steatohepatitis (NASH) and psoriasis is not completely understood. However, patients with psoriasis have more than a two-fold higher incidence of NASH, the severity of which tends to correlate with the severity of liver fibrosis and galectin-3 is increased in psoriatic skin. The genesis of this Phase 2a psoriasis treatment study was a 17 month remission in a NASH patient with severe psoriasis who participated in the Company's Phase 1 study cohort of 4 mg/kg of GR-MD-02 for the treatment of NASH (see CEO Perspective).
"This Phase 2a clinical trial will be extended so that all patients, including the four who have already completed treatment, will receive a total of 13 drug infusions," added Dr. Richie. "The one patient among the initial four with the least objective response in PASI was on a systemic retinoid therapy (acitretin) which was stopped one month before entering this study. Stopping this drug can lead to a long-term rebound effect, which may have contributed to the lower treatment response. Doubling the duration of therapy, and continued enrollment to the full 10 patients, will help us to evaluate the full therapeutic potential of GR-MD-02 in psoriasis."
The announced results are interim in that the originally scheduled 12 weeks of data has been obtained from only four of the ten patients who will participate in the trial. It is further interim in that the positive information obtained to this point has led to the trial being extended for all 10 study subjects in the trial.

About Psoriasis
Psoriasis, which manifests most often as plaque psoriasis, is a chronic, relapsing, inflammatory skin disorder. Although plaque psoriasis is rarely life threatening, it often is intractable to treatment. According to the International Federation of Psoriasis Associations, about 3% of the world's population has some form of psoriasis. In the U.S. there are about 150,000 new cases every year, and psoriasis affects about 2% of the U. S. population, according to the Cleveland Clinic.
About GR-MD-02
GR-MD-02 is a complex carbohydrate drug that targets galectin-3, a critical protein in the pathogenesis of fatty liver disease and fibrosis. Galectin-3 plays a major role in diseases that involve scarring of organs including fibrotic disorders of the liver, lung, kidney, heart and vascular system. The drug binds to galectin proteins and disrupts their function. Preclinical data in animals have shown that GR-MD-02 has robust treatment effects in reversing liver fibrosis and cirrhosis.
About Galectin Therapeutics
Galectin Therapeutics is developing promising carbohydrate-based therapies for the treatment of fibrotic liver disease and cancer based on the Company's unique understanding of galectin proteins, which are key mediators of biologic function. Galectin seeks to leverage extensive scientific and development expertise as well as established relationships with external sources to achieve cost-effective and efficient development. The Company is pursuing a development pathway to clinical enhancement and commercialization for its lead compounds in liver fibrosis and cancer.
