Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Following the Company’s decision to close its Phase 1 study of MRX34, in November 2016 the Company intends to reduce the total number of full-time employees from 36 to 12 to reduce operating expenses and streamline its operations. The Company expects the majority of the employees included in the reduction will be separated from the Company during the fourth quarter of 2016 and expects the remainder will discontinue employment with the Company during the first quarter of 2017. In addition, the Company has entered into retention agreements with certain employees necessary to close the Phase 1 trial of MRX34 and maintain the operations of the Company. The Company estimates that it will incur aggregate cash expenses of approximately $1.6 million under the workforce reduction, of which $1.3 million is attributed to one-time severance and benefits payments and $0.3 million relates to retention payments. In addition, depending on the outcome of the Company's evaluation of strategic alternatives, the Company may recognize an impairment to the carrying value of its fixed assets, additional costs associated with contract terminations, or a combination of both.
