Describe how the condition or disease for which this drug is used affects the day-to-day life of patients in your group. Type 2 diabetes is a chronic (progressive) condition that occurs when the pancreas does not produce enough insulin or when the body does not effectively use the insulin that is produced. Insulin is a hormone that controls the amount of glucose in the blood. Common symptoms of diabetes include fatigue, thirst and weight change. High blood glucose levels can cause long-term complications such as blindness, heart disease, kidney problems, nerve damage and erectile dysfunction. Diabetes requires considerable self-management, including healthy eating, regular physical activity, healthy body weight, taking diabetes medications (oral and/or injection) as prescribed, monitoring blood glucose and stress management. Poor glucose control can result in serious long-term complications. The majority of patients surveyed indicated that daily fluctuations in blood sugar were the most important aspect of diabetes to control during the day and overnight. The fluctuations impact the ability to work, interactions with friends and family, causes stress and worry as well as ability to participate in normal activities of daily living. Uncontrolled diabetes and the stigma associated with the disease can result in reduced quality of life. Maintaining control of diabetes has potential to reduce anxiety and avoid or delay complications as well as improve overall quality of life. Information presented in this section is derived from surveys conducted in 2014 and 2015 by the Canadian Diabetes Association (the CDA), distributed through social media and email blasts. These surveys asked about the reality and challenges of living with type 2 diabetes. There was a frequent emphasis on the psychological and emotional impact of diabetes on the lives of respondents (effect on stress, anxiety, adjusting to changes in diet and lifestyle, medication and treatment management as well as relationships with family). Respondents also described fatigue and lack of energy. 2 Management of diabetes includes lifestyle changes (diet, exercise and stress management). Inevitably, most patients are prescribed one or more medications to achieve glucose control. This usually starts with metformin (oral agent) and, if target glucose levels are not met, other medications are added. Over time most patients will be treated with multiple diabetes medications in order to achieve glycemic control. Below are selected quotes from respondents to our surveys when asked about challenges related to diabetes: “Having diabetes makes me useless. I have no energy or strength to enjoy life anymore. I can't do partial jobs around house. I can't enjoy sports anymore. Diabetes has instill [sic] a fear in me.” “It is a life altering disease that impacts every aspect of life. There is constant blood monitoring, diet, level of activity, cost of expensive supplies and medication.” “Basically it's an awful experience, experience highs and lows. Exercising can make my sugars low so I have to always have a snack with me. Eating anywhere besides home is a challenge as you don't know how things are made. I'm constantly checking my blood and I take 13 pills a day.” “The most distressing side effect of all of the diabetes drugs is they make you gain weight or prevent weight loss. It is annoying to be told to lose weight then handed a drug that prevents weight loss” 9. If the patients in your group have tried the drug under review, please tell us about the effects they experienced. The availability of dapagliflozin to offer an alternative treatment option for stabilizing blood glucose is important to patients. Dapagliflozin belongs to a new class of drugs to lower blood glucose through inhibition of subtype 2 sodium-glucose transport protein (SGLT2), which is responsible for at least 90% of the glucose reabsorption in the kidney. The SGLT2 inhibition also causes a reduction in blood pressure and weight loss. Information presented below was originally gathered from a survey conducted in April 2015 about the experience with the SGLT2 inhibitor drug dapagliflozin (Forxiga) to inform a patient input submission to the CDR. Questions from these surveys included current drug therapy, previous experience with drug therapy and experience with dapagliflozin (Forxiga). Data have been extracted from that survey for this submission. A total of 56 British Columbians completed the survey, 50 identified themselves as being diagnosed with type 2 diabetes, 4 indicated they were caregivers for people with type 2 diabetes. Among the respondents, 15 have experience with dapagliflozin. The majority of B.C. residents who have taken dapagliflozin noted its effectiveness in reducing blood sugar levels and reducing weight, with little to no side effects. Those who have experienced side effects cited increased hunger, dehydration and frequent urination. Below are some direct quotes from B.C. residents with type 2 diabetes who have used dapagliflozin: 3 “I've only been on Forxiga for a month ,but seems to be doing the job where the other was not quite working . side effects seem to be nil” “Easier to lose weight better for keeping my sugars in range. No lows” “better energy, no harmful side effects, weight reduction. Some late evening hunger experienced. Works well with other medications.” “as a once a day med, it keeps life simple” “instant reductions in sugar levels- my mom feels better on this medication and has lost 7 pounds. Has been a very positive experience for her.” Expectation for new drugs Responded to the survey indicated the most important benefits of a drug include its ability to keep blood glucose at target with minimized side effects. The majority of respondents indicated the following benefits/side effects of therapy were “quite” or” very important”: - blood sugars kept at satisfactory levels in the morning/after fasting (90%), - blood sugars kept at satisfactory levels during the day/after meals (90%), - avoiding fluid retention (90%), - avoiding weight gain (87%), - avoiding low blood sugar during the day/overnight (85%), - avoiding GI effects (85%), - reducing high blood pressure (85%), - avoiding urinary tract infection (80%). Respondents also indicated their expectations for new drugs, including affordability (“reducing the cost to retired persons with limited budgets”), better blood glucose control, less side effects (“such as low blood sugars”, “side effects that harm lungs, heart or other organs”), not having to depend on insulin (“keep away from the needle”, “reduce/eliminate need to injected insulin”), not having to depend on as many drugs (“reduce the dependence on drugs or number thereof”). One respondent hopes the new drugs will “allow [him/her] to lead as normal life as possible” and many express their wish for a cure. 10. What drugs or other treatments have the patients in your group used, or are currently using, for the condition or disease for which this drug is used? Please list all of the drugs and tell us about the experience of the patients in your group with each treatment. Three-quarters of the respondents reported current use of metformin, half of them reported current use of insulin, and one-third are using a sulfonylurea. Below we provide the list of drugs that the survey respondents indicated they are currently using, and the percentages of people using these drugs, based on 30-44 responses: - dapagliflozin (32%) - empagliflozin (3%) - canagliflozin (6%) - alogliptin+metformin (3%) 4 - DPP-4 inhibitors (11%) Saxagliptin+metformin (6%) Sitagliptin+metformin (8%) Linagliptin+metformin (6%) Rosiglitazone+metformin (3%) Metformin (75%) Sulfonylurea (31%) Meglitinides (3%) TZDs (6%) GLP-1 agonists (12%) Insulin (51%) Some people had to stop use of certain medications for reasons other than end of clinical trials; these medications include canagliflozin (3%), DPP-4 inhibitors (14%), sitagliptin+metformin (6%), metformin (5%), sulfonylurea (13%), meglitinides (3%), TZDs (15%), GLP-1 agonists (3%), and insulin (3%). Experience with current treatment While the majority of the respondents indicated satisfaction with their current treatment (60%), 21% indicated they are dissatisfied with the treatment, and 19% reported they are neither satisfied nor dissatisfied. Patients that answered our survey expressed preference for oral drugs (“hopefully [the drug can] reduce/eliminate need for injected insulin”) and for fewer pills needed for a day. One respondent reported weight gain associated with the insulin regimen. The majority of surveyed respondents (with use or without use of dapagliflozin) reported the treatment improved blood glucose and A1C levels. A large proportion reported their hypoglycemia and side effects (such as weight gain, GI effects, dehydration and urinary/yeast infections) did not improve with current therapies. Below are survey responses on effectiveness of current therapies, presented as % and number of responses in brackets ( ). Meeting target blood glucose (fasting) Meeting target blood glucose (postprandial) Meeting target blood glucose (upon waking) Avoiding hypoglycemia Meeting target A1C Weight control GI effects Dehydration UTI or yeast infection Worse 9% (4) Same 14% (6) Better 75% (33) 9% (4) 14% (6) 70% (30) 4% (2) 11% (5) 78% (35) 11% (5) 10% (4) 12% (5) 2% (1) 13% (5) 2% (1) 22% (10) 20% (8) 35% (15) 48% (21) 50% (20) 48% (20) 44% (22) 56% (33) 47% (20) 41% (18) 25% (10) 24% (10) 11. Please tell us why your organization believes this drug should be included in the BC PharmaCare program. 5 Diabetes requires intensive self-management. To achieve optimal blood glucose levels, individualization of therapy is essential, including selecting the drug or combination of drugs, route of administration (oral, injection, pen or pump), how frequently the patient monitors blood glucose and adjusts dosage, the benefits and risks that the patient experiences and/or tolerates, and the lifestyle changes the patient is willing or able to make. There are clear expectations that any new drugs should offer good blood glucose control to prevent hyperglycemic and hypoglycemic episodes, as well as longer term control, with minimal side effects or long term damage to organs, at affordable costs, and reducing dependency on other drugs including insulin injections. The patients who have experience with dapagliflozin described good results in terms of glucose control and less side effects compared with other drugs. Different people living with diabetes require different options in terms of medications to help effectively manage their disease; some people had to stop treatment for reasons other than clinical trials as seen in survey results. As noted by a respondent: “every person has their own response to a drug ... The [doctor] needs to be able to prescribe what is best for that patient (in regards to efficacy & or side effects.)”. Their clinical profile, preference and tolerance of therapy can direct physicians to the most appropriate drug therapy. The availability of dapagliflozin (Forxiga) thus provides an important option for patients. 6
