Debt Disclosure [Abstract]
LOAN AGREEMENT WITH KREOS AND RELATED WARRANT TO PURCHASE ORDINARY SHARES	LOAN AGREEMENT WITH KREOS AND RELATED WARRANT TO PURCHASE ORDINARY SHARES On December 30, 2015, the Company entered into the loan agreement (the "Loan Agreement") with Kreos Capital V (Expert Fund) Limited ("Kreos"), pursuant to which Kreos extended a line of credit to the Company in the amount of $20.0 million. For more information, see Note 6 to our audited consolidated financial statements included in our 2016 Form 10-K. On June 9, 2017, the Company and Kreos entered into the First Amendment of the Loan Agreement (the "Loan Amendment"). As of that date the outstanding principal amount under the Loan Agreement (the "Outstanding Principal") was $17.2 million. Under the Loan Amendment $3.0 million of the Outstanding Principal is extended by an additional 3 years with the same interest rate and is subject to repayment in accordance with, and subject to the terms of, a secured convertible promissory note (the "Kreos Convertible Note") into up to 2,365,931 ordinary shares of the Company at a fixed conversion price of $1.268 per share (subject to customary antidilution adjustments), thus reducing the Outstanding Principal Amount amount to $14.2 million. Kreos may convert the then-outstanding principal under the Kreos Convertible Note in whole or in part, in one or more occasions, at any time until the earlier of (i) the maturity date of June 9, 2020 or (ii) a Change of Control, as defined in the Loan Agreement. The Outstanding Principal Amount under the Loan Agreement is not convertible and remains subject to repayment in accordance with the terms and conditions of the Loan Agreement, provided that such amount shall be repaid by the Company in accordance with an amended repayment schedule. The Company concluded that the exchange of the $3.0 million for the convertible promissory note is not a troubled debt restructuring under applicable accounting guidance because the lenders did not grant a concession. The modification was analyzed under ASC 470 Debt to determine if extinguishment accounting was applicable. Under ASC 470-50-40-10 a modification or an exchange that adds or eliminates a substantive conversion option as of the conversion date is always considered substantial and requires extinguishment accounting. Since this modification added a substantive conversion option, extinguishment accounting is applicable. The difference between the fair value of the new debt with the pre-modification carrying amount of the old debt represented a loss on extinguishment in the amount of $313 thousand. According to the Loan Agreement the repayment period will be extended to 36 months if the Company raises $20 million or more in connection with the issuance of shares of its capital stock (including debt securities convertible into shares of the Company’s capital stock). As of June 30, 2017 the Company had raised more than $20 million and therefore the repayment period was extended by an additional 12 months to 36 months.
