One of these chemicals is known as "Pancreatic Polypeptide" (PP). We have previously shown that injections of human PP reduces appetite and food intake. We have now developed a very similar chemical, PP 1420, as a treatment for obesity. PP 1420 has been tested in animals and has been shown to be safe, and to reduce their appetite. This study will test PP 1420 for its safety and tolerability in humans.', 'detailedDescription': 'More than 20 percent of people in the UK are obese. People with obesity have a shorter life expectancy, and have a higher risk of having heart attacks, strokes, high blood pressure, diabetes, and certain cancers.\n\nAt the moment, there is no treatment for obesity that is both effective and safe. Advising people to change their diet and to exercise more is frequently ineffective, and any loss in weight seen is usually temporary. There are a couple of licensed medications for the purpose of losing weight, but they are limited by side effects. Finally, gastric bypass and similar surgeries are effective at reducing weight permanently, but it can be risky and is restricted only to very motivated people.\n\n"Gut hormones" are natural chemicals made by the bowels when you eat. They work to reduce appetite and hunger when you eat, so that you will eat enough for your needs. We think that one of the reasons why gastric bypass surgery is so effective is because the surgery causes an increase in gut hormone secretion into the bloodstream, which suppresses appetite. One of these hormones is pancreatic polypeptide (PP), which is released into the bloodstream by cells in the pancreas after eating. When human PP is given to healthy volunteers as an injection, we see that they have a reduced appetite and food intake with no side effects such as feeling sick or vomiting.\n\nHuman PP does not last long in the blood stream. In order to make it into a new, safe and effective drug for obesity, we have developed a new form of PP, which is very similar but not identical to human PP, that we expect will last longer in the blood. We call this PP 1420.\n\nIn testing, PP 1420 reduced food intake in animals, and was safe in them at much higher doses than those we plan to give in the current study. This study will assess the safety and tolerability of PP 1420 in humans, and is the first time humans have been given this medication.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT'], 'maximumAge': '50 Years', 'minimumAge': '18 Years', 'genderBased': True, 'genderDescription': 'Healthy male', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Healthy male as determined by a responsible physician, based on a medical evaluation including history, physical examination, vital signs, laboratory tests and 12-lead ECG.\n* Between 18 and 50 years of age, inclusive, at the time of signing and dating the informed consent form.\n* Body weight ≥70 kg and body mass index (BMI) within the range 18 - 35 kg/m2 (inclusive).\n* Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.\n* Willing and able to comply with the protocol for the duration of the study.\n\nExclusion Criteria:\n\n* As a result of the medical interview, physical examination, or screening investigations, the Investigator considers the subject unsuitable for the study.\n* The subject has a positive pre-study drug/alcohol screen.
