Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A lifestyle intervention program, using a 12-week adaptation of the Arena Healthy Lifestyles Program, including diet and exercise counseling, will be implemented for obesity/overweight.
Blood sampling will be performed to evaluate the pharmacokinetics (PK) of lorcaserin and phentermine using population PK modeling as well as the potential relationships between exposure to the lorcaserin/phentermine and measures of safety and change from baseline in body weight, using population PK/PD (pharmacodynamics) modeling.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Ambulatory and able to perform moderate exercise.
3. Male or female subjects between 18 and 60 years at the time of informed consent.

3. Use of selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) (including buproprion) for reasons other than active psychiatric indications (e.g., migraine, weight loss, smoking cessation) within 1 month prior to the Screening Visit).
4. Medication history that includes use of one or more of the following:
1. Fenfluramine or related derivatives (i.e., dexfenfluramine, norfenfluramine)
2. Agents that have documented correlation with increased incidence of valvulopathy and/or primary pulmonary hypertension (e.g., cabergoline, cyproheptadine, trazodone, nefazodone, amoxapine, mirtazapine, pergolide, ergotamine, methysergide)
5. Recent treatment (i.e., within 1 month of the Screening Visit and any time prior to randomization or thereafter during the study) with over-the-counter (OTC) weight loss products or appetite suppressants (including herbal weight loss agents), or within 6 months and any time prior to randomization or thereafter during the study, with a prescription weight loss drug (e.g., phentermine, phentermine/topiramate, orlistat).
6. Use of St. John's Wort within 1 month prior to the Screening Visit and for the duration of the study. St. John's Wort has been associated with serotonin syndrome when used with another serotonergic drug.
7. Hypersensitivity to sympathomimetic amines or the study drugs.
8. History of stroke, transient ischemic attack, arrhythmias, congestive heart failure, and/or peripheral vascular disease.
9. Recent history of active cardiovascular disease, including chronic stable angina or an unstable angina episode or myocardial infarction within the 3 months prior to the Screening Visit.
10. Uncontrolled hypertension defined as systolic blood pressure greater than or equal to 150 or diastolic blood pressure greater than or equal to 95 on 2 readings taken on different days. Subjects who have uncontrolled hypertension at screening may be re-screened greater than 1 month following initiation or adjustment of antihypertensive therapy.
11. History of or active pulmonary artery hypertension.
12. Severe renal impairment (creatinine clearance less than 30 mL/min, as calculated by the Cockroft-Gault equation based on ideal body weight) or end stage renal disease.
13. History of valve replacement surgery; clinically significant valvular stenosis; history of or active clinically significant valvulopathy (defined as aortic insufficiency of mild, moderate, or severe intensity and/or mitral insufficiency of moderate or severe intensity).
14. History of or active (confirmed fasting glucose greater than 126 mg/dL or hemoglobin A1c \[HbA1c\] greater than ULN \[6.5% at central laboratory\]) diabetes mellitus (type I, II or other) and/or currently taking medications for type I or II diabetes. A past history of gestational diabetes that has resolved is permissible.
15. Glaucoma.
16. Abnormal thyroid stimulating hormone (TSH) laboratory value greater than 1.5 x Upper Limit of Normal (ULN)

18. Recent history (within 2 years prior to the Screening Visit) of alcohol or drug/solvent abuse or a positive screen for drugs of abuse at screening.
19. Significant change is smoking habits or tobacco product use within 3 months prior to the Screening Visit.
20. Use of tobacco products (i.e., smokes more than one-half pack of cigarettes per day, or smokes more than 2 cigars per day, or uses 3 or more pinches of smokeless tobacco per day).
21. Surgical procedure for the treatment of obesity (i.e., gastric bypass, gastric banding), even if reversed prior to screening.
22. Planned surgery during the study period that may interfere with completion or compliance with the protocol.
23. A prolonged QT/QTc interval (QTc Bazett's greater than 450 msec) as demonstrated by a repeated electrocardiogram (ECG).
24. Participation in any clinical study with an investigational drug, biologic, or device within 1 month prior to screening.
25. Significant change in diet or level of physical activity within 1 month prior to dosing that in the opinion of the investigator(s) may confound the results of the study.
26. Change in weight of greater than 5 kg within 3 months of screening.
27. Use of a very-low calorie (less than 800/day) liquid weight loss diet within 6 months prior to screening and any time prior to randomization.
28. Eligible male and female subjects participating in a conception process (i.e., active attempt to become pregnant or to impregnate, sperm donation, in vitro fertilization).
29. Females who are lactating or pregnant at Screening or Baseline Visit (as documented by a negative serum or urine pregnancy test with a minimum sensitivity of 25 IU/L or equivalent units of beta-human chorionic gonadotropin \[B-hCG\]). A separate baseline assessment is required if a negative screening pregnancy test was obtained more than 72 hours before the first dose of study drug.
30. All females will be considered to be of childbearing potential unless they are postmenopausal (amenorrheic for at least 12 consecutive months, in the appropriate age group and without other known or suspected cause) or have been sterilized surgically (i.e., bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy, all with surgery at least one month before dosing).
31. Females of childbearing potential must not have had unprotected sexual intercourse within 30 days before study entry and must agree to use a highly effective method of contraception (e.g., total abstinence, an intrauterine device, a double-barrier method \[such as condom plus diaphragm with spermicide\], a contraceptive implant, an oral contraceptive, or have a vasectomized partner with confirmed azoospermia) throughout the entire study period and for 30 days after study drug discontinuation. If currently abstinent, the subject must agree to use a double barrier method as described above if she becomes sexually active during the study period or for 30 days after study drug discontinuation. Females who are using hormonal contraceptives must have been on a stable dose of the same hormonal contraceptive product for at least 4 weeks before dosing and must continue to use the same contraceptive during the study and for 30 days after study drug discontinuation. Females not meeting these criteria will be excluded from the study.
32. Any medical or other condition that in the opinion of the investigator(s) would preclude the subject's participation in a clinical study, such as significantly abnormal laboratory results or any physical or mental condition that prevents compliance with the protocol.
