Business Combinations [Abstract]
Acquisitions	ACQUISITIONS Cerulean/Private Daré Stock Purchase Transaction In July 2017, the Company completed its business combination with Daré Bioscience Operations, Inc., a privately held Delaware corporation, or Private Daré, in which Private Daré stockholders sold their shares to the Company in exchange for newly issued shares of the Company’s common stock, and as a result, Private Daré became a wholly owned subsidiary of the Company and the Private Daré stockholders became majority stockholders of the Company. In connection with the closing of that transaction, the Company changed its name from “Cerulean Pharma Inc.” to “Daré Bioscience, Inc.” In this report, that transaction is referred to as the Cerulean/Private Daré stock purchase transaction and “Cerulean” refers to Cerulean Pharma Inc. before that transaction closed. The Cerulean/Private Daré stock purchase transaction was accounted for as a reverse merger under the acquisition method of accounting whereby Private Daré was considered to have acquired Cerulean for financial reporting purposes. Pursuant to business combination accounting, the Company applied the acquisition method, which requires the assets acquired and liabilities assumed be recorded at fair value with limited exceptions. The excess of the purchase price over the assets acquired and liabilities assumed represents goodwill. The goodwill was primarily attributable to the cash and cash equivalents at closing of the transaction of approximately $9.9 million and the impact of the unamortized fair value of stock options granted by Cerulean that were outstanding immediately before the transaction closed of approximately $3.7 million. The Company tests its goodwill for impairment at least annually as of December 31 and between annual tests if it becomes aware of an event or change in circumstance that would indicate the carrying value may be impaired. The Company tests goodwill for impairment at the entity level because it operates on the basis of a single reporting unit. A goodwill impairment is the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. When impaired, the carrying value of goodwill is written down to fair value. Any excess of the reporting unit goodwill carrying value over the fair value is recognized as impairment loss. The Company assessed goodwill at March 31, 2018, determined there was an impairment and recognized an impairment charge of approximately $5.2 million in the interim consolidated statement of operations and comprehensive loss for the three months ended March 31, 2018. As of March 31, 2018, the goodwill carrying value on the Company’s consolidated balance sheet was written off in its entirety. Pear Tree Merger On April 30, 2018, the Company entered into an Agreement and Plan of Merger, the Merger Agreement, with Pear Tree Pharmaceuticals, Inc., or Pear Tree, Daré Merger Sub, Inc., a wholly-owned subsidiary of the Company, or Merger Sub, and two individuals in their respective capacities as Pear Tree stockholders’ representatives. The transactions contemplated by the Merger Agreement closed on May 16, 2018, and as a result, Pear Tree became the Company’s wholly owned subsidiary. The Company acquired Pear Tree to secure the rights to develop DARE-VVA1, a proprietary vaginal formulation of tamoxifen, as a potential treatment for vulvar and vaginal atrophy. The Company determined that the acquisition of Pear Tree should be accounted for as an asset acquisition instead of a business combination because substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, and therefore, the asset is not considered a business. Transaction costs of approximately $452,000 associated with the merger were included in the Company’s research and development expense. Under the Merger Agreement, certain former and continuing Pear Tree service providers and former holders of Pear Tree’s capital stock, or the Holders, were eligible to receive a $75,000 payment due on the one-year anniversary of the closing of the merger and are eligible to receive tiered royalties, subject to customary provisions permitting royalty reductions and offset, based on percentages of annual net sales of certain products subject to license agreements the Company assumed and a percentage of sublicense revenue. The Company must also make contingent payments to the Holders based on achieving certain clinical, regulatory and commercial milestones, which may be paid, in the Company’s sole discretion, in cash or shares of the Company’s common stock. In accordance with the terms of the Merger Agreement, because the Negative Consideration Amount (as defined below) exceeded the Positive Consideration Amount (as defined below), at the time of the closing of the merger, the excess amount (approximately $132,000) offset the $75,000 payment due on the one-year anniversary of the closing of the merger and the balance will offset future payments otherwise due under the Merger Agreement to the Holders. Positive Consideration Amount means the sum of $75,000, and the cash and cash equivalents held by Pear Tree at closing, and Negative Consideration Amount means the sum of (i) certain Pear Tree indebtedness and transaction expenses, (ii) transaction expenses of the stockholders’ representatives, and (iii) amounts payable under Pear Tree’s management incentive plan.

ACQUISITIONS

Cerulean/Private Daré Stock Purchase Transaction

In July 2017, the Company completed its business combination with Daré Bioscience Operations, Inc., a privately held Delaware corporation, or Private Daré, in which Private Daré stockholders sold their shares to the Company in exchange for newly issued shares of the Company’s common stock, and as a result, Private Daré became a wholly owned subsidiary of the Company and the Private Daré stockholders became majority stockholders of the Company. In connection with the closing of that transaction, the Company changed its name from “Cerulean Pharma Inc.” to “Daré Bioscience, Inc.” In this report, that transaction is referred to as the Cerulean/Private Daré stock purchase transaction and “Cerulean” refers to Cerulean Pharma Inc. before that transaction closed.

The Cerulean/Private Daré stock purchase transaction was accounted for as a reverse merger under the acquisition method of accounting whereby Private Daré was considered to have acquired Cerulean for financial reporting purposes. Pursuant to business combination accounting, the Company applied the acquisition method, which requires the assets acquired and liabilities assumed be recorded at fair value with limited exceptions. The excess of the purchase price over the assets acquired and liabilities assumed represents goodwill. The goodwill was primarily attributable to the cash and cash equivalents at closing of the transaction of approximately $9.9 million and the impact of the unamortized fair value of stock options granted by Cerulean that were outstanding immediately before the transaction closed of approximately $3.7 million.

The Company tests its goodwill for impairment at least annually as of December 31 and between annual tests if it becomes aware of an event or change in circumstance that would indicate the carrying value may be impaired. The Company tests goodwill for impairment at the entity level because it operates on the basis of a single reporting unit. A goodwill impairment is the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. When impaired, the carrying value of goodwill is written down to fair value. Any excess of the reporting unit goodwill carrying value over the fair value is recognized as impairment loss.

The Company assessed goodwill at March 31, 2018, determined there was an impairment and recognized an impairment charge of approximately $5.2 million in the interim consolidated statement of operations and comprehensive loss for the three months ended March 31, 2018. As of March 31, 2018, the goodwill carrying value on the Company’s consolidated balance sheet was written off in its entirety.

Pear Tree Merger

On April 30, 2018, the Company entered into an Agreement and Plan of Merger, the Merger Agreement, with Pear Tree Pharmaceuticals, Inc., or Pear Tree, Daré Merger Sub, Inc., a wholly-owned subsidiary of the Company, or Merger Sub, and two individuals in their respective capacities as Pear Tree stockholders’ representatives. The transactions contemplated by the Merger Agreement closed on May 16, 2018, and as a result, Pear Tree became the Company’s wholly owned subsidiary. The Company acquired Pear Tree to secure the rights to develop DARE-VVA1, a proprietary vaginal formulation of tamoxifen, as a potential treatment for vulvar and vaginal atrophy.

The Company determined that the acquisition of Pear Tree should be accounted for as an asset acquisition instead of a business combination because substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, and therefore, the asset is not considered a business. Transaction costs of approximately $452,000 associated with the merger were included in the Company’s research and development expense.

Under the Merger Agreement, certain former and continuing Pear Tree service providers and former holders of Pear Tree’s capital stock, or the Holders, were eligible to receive a $75,000 payment due on the one-year anniversary of the closing of the merger and are eligible to receive tiered royalties, subject to customary provisions permitting royalty reductions and offset, based on percentages of annual net sales of certain products subject to license agreements the Company assumed and a percentage of sublicense revenue. The Company must also make contingent payments to the Holders based on achieving certain clinical, regulatory and commercial milestones, which may be paid, in the Company’s sole discretion, in cash or shares of the Company’s common stock.

In accordance with the terms of the Merger Agreement, because the Negative Consideration Amount (as defined below) exceeded the Positive Consideration Amount (as defined below), at the time of the closing of the merger, the excess amount (approximately $132,000) offset the $75,000 payment due on the one-year anniversary of the closing of the merger and the balance will offset future payments otherwise due under the Merger Agreement to the Holders. Positive Consideration Amount means the sum of $75,000, and the cash and cash equivalents held by Pear Tree at closing, and Negative Consideration Amount means the sum of (i) certain Pear Tree indebtedness and transaction expenses, (ii) transaction expenses of the stockholders’ representatives, and (iii) amounts payable under Pear Tree’s management incentive plan.
