January 31, 2020 — The US Food and Drug Administration (FDA) has approved Dificid (fidaxomicin) tablets and oral suspension for the treatment of pediatric patients with Clostridioides difficile (C. difficile), a bacterium that causes diarrhea and colitis. For more information, please see here.

February 10, 2020 — Palette Life Sciences, Inc., a medical device company dedicated to assisting healthcare professionals (HCPs) to improve patient outcomes in colorectal urologic and oncologic conditions and diseases, today announced the launch of the Solesta® Reimbursement Assistance Program. Solesta is a minimally-invasive, and easily injectable viscous gel made from two polysaccharides, Non-Animal Stabilized Hyaluronic Acid (NASHA®) and Dextranomer (Dx) microspheres.1 Solesta is the only quick, nonsurgical treatment for fecal incontinence, administered in an outpatient setting without the need for anesthesia.2 HCPs can simply follow three steps at MySolesta.com to become trained in Solesta administration and technique. Studies have shown that Solesta can help patients return to a more active lifestyle (socializing, going to work, etc.) and reduces the depression and embarrassment that is often associated with bowel control problems.

February 13, 2020 — The US Food and Drug Administration (FDA) has approved a new treatment for chronic idiopathic constipation (CIC). The approval allows Braintree Laboratories to move forward with lactitol (Pizensy), an osmotic laxative indicated for the treatment of CIC in adults for a recommended dosage of 20 grams orally daily.

February 14, 2020 – Takeda Pharmaceutical Company Limited (TSE:4502/NYSE:TAK) (“Takeda”) today announced results from the phase 3 VISIBLE 2 clinical trial evaluating the efficacy and safety of an investigational subcutaneous (SC) formulation of the gut-selective biologic vedolizumab (Entyvio®) for use during maintenance therapy in adult patients with moderately to severely active Crohn's disease (CD). The study evaluated patients who achieved clinical response* at week 6 following two doses of open-label vedolizumab intravenous (IV) induction therapy at weeks 0 and 2.[1] The results show that at week 52, significantly more patients on vedolizumab SC compared to placebo were in clinical remission (48.0% [n=132/275] vs. 34.3% [n=46/134] respectively; [p=0.008]),** meeting the study’s primary endpoint.1 These data were announced during an oral presentation at the 15th Congress of the European Crohn’s and Colitis Organisation (ECCO) in Vienna, Austria.

February 25, 2020 — WASHINGTON/PRNewswire/ -- Vanda Pharmaceuticals Inc. (Vanda) (Nasdaq:VNDA) today announced results from a Phase III clinical trial (EPIONE) of tradipitant for the treatment of pruritus in atopic dermatitis (AD) in adults. The EPIONE study did not meet its primary endpoint in reduction of pruritus across the overall study population. However, the antipruritic effect of tradipitant was robust in the mild AD study population. Mild AD represents over 60% of the total AD population in the U.S.1, 2 The EPIONE study continued to demonstrate that tradipitant is safe and well-tolerated.

March 9th, 2020 — TEL-AVIV, Israel and RALEIGH, N.C., RedHill Biopharma Ltd. (Nasdaq: RDHL) (“RedHill” or the “Company”), a specialty biopharmaceutical company focused on gastrointestinal diseases, today announced the U.S. commercial launch of Talicia® (omeprazole magnesium, amoxicillin and rifabutin)1 delayed-release capsules 10 mg2/250 mg/12.5 mg for the treatment of Helicobacter pylori (H. pylori) infection in adults. RedHill’s expanded U.S. sales force will promote Talicia® nationwide to approximately 25,000 gastroenterologists, primary care physicians and other healthcare providers.

March 24, 2020 — FDA is informing health care providers and patients of the potential risk of transmission of SARS-CoV-2 virus by the use of fecal microbiota for transplantation (FMT) and that FDA has determined that additional safety protections are needed.

Several recent studies have documented the presence of SARS-CoV-2 ribonucleic acid (RNA) and/or SARS-CoV-2 virus in stool of infected individuals. This information suggests that SARS-CoV-2 may be transmitted by FMT, although the risk of such transmission is unknown. At this time, testing nasopharyngeal specimens from stool donors for SARS-CoV-2 may not be widely available. Furthermore, there is limited information on the availability and sensitivity of direct testing of stool for SARS-CoV-2.

As the scientific community learns more about SARS-CoV-2 and COVID-19, FDA will provide further information as warranted.

April 1, 2020 — The U.S. Food and Drug Administration today announced it is requesting manufacturers to withdraw all prescription and over-the-counter (OTC) ranitidine drugs from the market immediately. This is the latest step in an ongoing investigation of a contaminant known as N-Nitrosodimethylamine (NDMA) in ranitidine medications (commonly known by the brand name Zantac). The agency has determined that the impurity in some ranitidine products increases over time and when stored at higher than room temperatures and may result in consumer exposure to unacceptable levels of this impurity. As a result of this immediate market withdrawal request, ranitidine products will not be available for new or existing prescriptions or OTC use in the U.S.

“The FDA is committed to ensuring that the medicines Americans take are safe and effective. We make every effort to investigate potential health risks and provide our recommendations to the public based on the best available science. We didn’t observe unacceptable levels of NDMA in many of the samples that we tested. However, since we don’t know how or for how long the product might have been stored, we decided that it should not be available to consumers and patients unless its quality can be assured,” said Janet Woodcock, M.D., director of the FDA’s Center for Drug Evaluation and Research. “The FDA will continue our efforts to ensure impurities in other drugs do not exceed acceptable limits so that patients can continue taking medicines without concern.”

April 15, 2020 - The U.S. Food and Drug Administration has announced that Amneal Pharmaceuticals, LLC, Bridgewater, New Jersey is voluntarily recalling three lots of Nizatidine Oral Solution, 15 mg/mL (75 mg/5mL), packaged in 480 mL bottles to the Consumer Level. This recall is due to potential N-Nitrosodimethylamine (NDMA) amounts exceeding the levels established by the FDA. Read the full announcement here.

Treatment News Presented at ACG 2018

In October 2018, IFFGD gathered with clinicians, researchers, drug developers and manufacturers, and others at the American College of Gastroenterology (ACG) annual meeting in Philadelphia, PA to get the latest research updates in the field of digestive health. Major medical meetings, like ACG, present companies with an opportunity to share news on developments in drug treatments. Here are a selection of drug developments announced at ACG this year:

  • Long-term safety data was presented for the drug tenapanor for irritable bowel syndrome with constipation (IBS-C). In several previous Phase III trials, tenapanor was found to effectively reduce constipation and abdomial pain in patients with IBS-C. The most common side effect of the drug is diarrhea (9.2%).
  • Clinical data showing improvement in health-related quality of life and the effects on esophageal erosions were presented for IW-3718 for the treatment of persistent gastroesophageal reflux disease (GERD). Persistent GERD is defined as the persistent occurrence of heartburn and regurgitation despite standard treatment of proton pump inhibitors (PPIs). Phase III clinical trials are currently undergoing to assess the safety and effectiveness of IW-3718.
  • Safety and efficacy data were presented for plecanatide for the treatment of IBS-C and chronic idiopathic constipation (CIC) in patients 65 years and older compared with patients younger than 65 years. Safety (adverse event and discontinuation rates) and efficacy were consistently demonstrated between the two populations.
  • Results of a two year follow-up study confirm safety and tolerability of a novel delivery of peppermint oil for the dietary management of IBS. The most common self-reported side effects were abdominal pain/discomfort/distension, diarrhea, and dyspepsia.
  • Safety and effeicacy data were presented for eluxadoline in patients with IBS with diarrhea (IBS-D) who reported inadequate symptom control with over-the-counter (OTC) loperamide. Eluxadoline is not indicated for patients without a gallbladder.
