|Insys Therapeutics, Inc. Issues Statement|
Insys is committed to developing products for the supportive care of patients through the use of its drug delivery technologies. Insys takes patient safety very seriously and is committed to working with the health care community, including health care providers, or HCPs, payors, pharmacies, and most importantly, patients to help ensure the proper prescribing and use of its products.
Insys is the manufacturer of Subsys®, the first and only fentanyl sublingual spray. Subsys is indicated for the management of breakthrough pain in cancer patients 18 years of age and older who are already receiving and who are tolerant to opioid therapy for their underlying persistent cancer pain. Please see “Important Safety Information About Subsys” below. Subsys belongs to a class of opioids known as Transmucosal Immediate Release Fentanyl products, or TIRF, the first of which was introduced over 15 years ago. Insys began to sell Subsys on
TIRF REMS PROGRAM
Under the TIRF Risk Evaluation and Mitigation Strategy, or REMS, program, outpatients, healthcare professionals who prescribe to outpatients, pharmacies, and distributors must enroll in the program. TIRF products can be prescribed and dispensed only after physicians and pharmacies have undergone training on the risks and benefits of such products and have enrolled in the TIRF REMS program. As stated on the website for the TIRF REMS program, in 2012, the
Insys has a compliance program in place with protocols that are designed to ensure its sales and marketing practices comply with applicable laws. Since the commercial launch of Subsys, Insys has focused its educational and promotional activities on REMS-enrolled providers. Insys’ sales representatives are only permitted to call on REMS-enrolled HCPs, oncologists or individuals who have previously prescribed TIRF products and Insys only utilizes REMS-enrolled physicians as promotional speakers (subject to additional company mandated controls).
Based on its interactions with patients and prescribers, Insys believes that the success of Subsys is directly attributable to the clinical benefits of its product. The sublingual spray technology utilized for Subsys is a unique vehicle for delivery of medicines where fast onset of action and convenience is needed. Characteristics unique to the device lend themselves to ensuring that the medicine is applied through a fine mist to a large section of the submucosal area. Furthermore, since the product is delivered sublingually (i.e., under the tongue), the thin submucosa layer of the tongue lends itself to fast absorption of the medicine. Ultimately, Subsys offers key differences from the competitors in this TIRF class:
While Subsys’s share of the TIRF market has grown significantly since it was launched in 2012, the overall total number of TIRF prescriptions in 2014 was only slightly higher than the total number of TIRF prescriptions in the year of the launch of Subsys (2012) and was actually materially lower than the total number of prescriptions in the year prior to the launch of Subsys and the TIRF REMS program (2011). Given these facts and other relevant information, Insys believes that existing data strongly support that prescribing decisions have been driven primarily by the clinical attributes of Subsys and its market share gains have come from patients and HCP’s switching to Subsys from other TIRF products.
According to data available from Source Health Analytics, the total number of opioid prescriptions written in the past 12 months were over 190 million. TIRF products represents less than 0.07% of all opioid prescriptions. Furthermore, Subsys represents only 0.03% of all opioid prescriptions, or approximately 56,000 of the 190 million opioid prescriptions written in the past 12 months. Figure 1 below illustrates these data.
The REMS program for TIRF products to which Subsys belongs, does not exist for most abused opioids like hydrocodone and oxycodone. The Company believes that the lack of a REMS program may contribute to the abuse of these products.* Also, as is evident (from Figure 1 above), TIRF product scripts are only a fraction of all opioids. Insys strives to comply with all
As previously disclosed by Insys, in connection with the investigation by the
The Company’s unique sublingual technology is being utilized by Insys in a variety of other pipeline products some of which seek to address the concern of opioid abuse including: (a) the development of a naloxone sublingual spray candidate for potential use in rescuing patients in opioid overdose (b) the development of a buprenorphine sublingual spray candidate for potential use in acute and chronic pain, and (c) the development of a buprenorphine/naloxone sublingual spray candidate for potential use in managing opioid addiction.
The Company realizes that the cancer patient population is underserved, and in addition to the spray candidates mentioned above, hopes to introduce Syndros®, its proprietary dronabinol oral solution post FDA approval. This product will potentially be indicated for treating chemotherapy induced nausea and vomiting (CINV) and for appetite stimulation in AIDS patients. Furthermore the Company is undertaking research in a liposomal encapsulated paclitaxel product candidate in gastric and ovarian cancers. Cannabidiol is also being researched by the Company for a spectrum of indications including epilepsy and a wide variety of unmet needs. Insys plans to spend approximately $100 million in 2016 in developing all of the above projects.
*Both Hydrocodone and Oxycodone now have REMS programs in place. Zohydro ER (hydrocodone) was approved in 2012 with a REMS and OxyContin controlled-release was approved in 2010 with a REMS.
Important Safety Information About Subsys
Due to the risk of fatal respiratory depression, Subsys is contraindicated in opioid non-tolerant patients and in management of acute or postoperative pain, including headache/migraines. The most serious adverse reactions associated with all opioids including Subsys are respiratory depression (potentially leading to apnea or respiratory arrest), circulatory depression, hypotension, and shock. The most common adverse reaction leading to discontinuation of Subsys was nausea. There were also adverse reactions of abdominal distention, anorexia, confusional state, disorientation, somnolence, and constipation.
About Insys Therapeutics, Inc.
Insys Therapeutics is a specialty pharmaceutical company that develops and commercializes innovative drugs and novel drug delivery systems of therapeutic molecules that improve the quality of life of patients. Using proprietary sublingual spray technology and capabilities to develop pharmaceutical cannabinoids, Insys addresses the clinical shortcomings of existing commercial products. Insys currently markets one product: Subsys® (fentanyl sublingual spray). The Company recently submitted a New Drug Application to the U.S. Food and Drug Administration for Syndros® (dronabinol oral solution), a proprietary, orally administered formulation of dronabinol that Insys believes has distinct advantages over the current formulation of dronabinol in soft gel capsule. Insys is developing a pipeline of sublingual sprays, as well as pharmaceutical cannabidiol.
