Label indication ROZEREM ® is indicated for the treatment of insomnia characterized by difficulty with sleep onset. The clinical trials performed in support of efficacy were up to six months in duration. The final formal assessments of sleep latency were performed after two days of treatment during the crossover study (elderly only), at five weeks in the six week studies (adults and elderly), and at the end of the six month study… FDA label

Elapsed time from the beginning of the Polysomnography recording to the onset of the first 10 minutes of continuous sleep was measured over 2 nights and the average time to sleep was calculated.
Time to sleep onset as determined by polysomnography
The elapsed time from the beginning of the polysomnography recording to the onset of the first 10 minutes of continuous sleep (ie, total number of epochs before the first 20 consecutive non-wake epochs divided by 2).
Maximum observed serum concentration (Cmax) is the peak serum concentration of ramelteon and its metabolite (M-II) after administration, obtained directly from the serum concentration-time curve.
Tmax: Time to reach the maximum serum concentration (Cmax) of ramelteon and its metabolite M-II, equal to time (hours) to Cmax.
Area under the serum concentration-time curve from time 0 to time of last quantifiable concentration (tlqc) of ramelteon and its metabolite M-II, calculated using the linear trapezoidal rule.
Area under the serum concentration-time curve from time zero extrapolated to infinity for ramelteon and its metabolite M-II. The terminal area from the last quantifiable concentration (lqc) to infinity is calculated by approximation: lqc / terminal elimination rate constant (λz).
Apparent oral clearance of drug from the serum calculated as: CL/F = Dose / Area under the serum concentration-time curve from time 0 extrapolated to infinity (AUC\[0-inf\]).
The rate at which ramelteon and its metabolite M-II are eliminated from the body, calculated as the negative of the slope of the log-linear regression of the natural logarithm concentration-time curve during the terminal phase.
Terminal phase elimination half-life (T1/2) for ramelteon and its metabolite M-II is the time required for half of the drug to be eliminated from the serum, calculated as T1/2 = natural logarithm of 2 (ln\[2\]) / Terminal elimination rate constant (λz).
Vz/F is the distribution of a drug between plasma and the rest of the body following oral administration, calculated as Vz/F = Apparent oral clearance (CL/F) / Terminal elimination rate constant (λz).

Rozerem is used for the treatment of insomnia. It is a small molecule being developed by Takeda Pharmaceutical Company Limited. In clinical trials, it has been studied for insomnia in elderly patients with obstructive sleep apnea. The drug is currently in Phase 3 clinical development.
Rozerem targets the melatonin receptors in the brain. It works by binding to these receptors to help regulate the sleep-wake cycle, which can improve sleep onset in patients with insomnia. This mechanism is particularly relevant for elderly patients who may have disrupted circadian rhythms.
Rozerem is developed by Takeda Pharmaceutical Company Limited, a global biopharmaceutical company. Takeda is publicly traded under the ticker symbol TAK. The company is conducting clinical trials to evaluate the safety and efficacy of Rozerem for the treatment of insomnia.
Rozerem is in Phase 3 clinical development. It is an investigational drug and has not been approved by regulatory authorities. One Phase 3 clinical trial has been completed, which studied the drug in elderly patients with insomnia and obstructive sleep apnea.
Rozerem has been studied in one completed Phase 3 clinical trial with the identifier NCT01048242. This trial, titled 'Treatment of Insomnia in Elderly Sleep Apnea Patients With Ramelteon (TAK 375)', enrolled 27 participants in the United States. The study was randomized, double-blind, and placebo-controlled.
Yes, Rozerem is the brand name for ramelteon, which is also known as TAK 375. The clinical trial NCT01048242 refers to the drug as ramelteon (TAK 375). This medication is being developed by Takeda Pharmaceutical Company Limited for the treatment of insomnia.
