Fair Value Measurements | 4. Fair Value Measurements ASC Topic 820, Fair Value Measurements and Disclosures Financial Instruments Level 1—Inputs are based upon observable or quoted prices for identical instruments traded in active markets. Level 2—Inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company’s Level 2 investments consist primarily of corporate notes and bonds and U.S. government and agency securities. Level 3—Inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models, and similar techniques. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value. The Company’s marketable securities consist of corporate bonds and a government bond which are adjusted to fair value at each balance sheet date, based on quoted prices, which are considered Level 2 inputs. During the three and nine months ended September 30, 2019, a non-recurring fair value measurement was applied to determine the fair value of the non-cash consideration received related to the joint venture with Bayer. The fair value measurement was determined using an income approach based primarily on utilizing management’s estimates of future cash flows as inputs which are considered Level 3 measurements within the above fair value hierarchy. The following is a summary of the Company’s available-for-sale securities as of September 30, 2019 and December 31, 2018: September 30, 2019 Gross Gross Description Effective Maturity Amortized Cost Unrealized Gains Unrealized Losses Fair Value Corporate bonds 2019 $ 46,836,782 22,172 — $ 46,858,954 Government bonds 2019 2,993,900 3,757 — 2,997,657 Corporate bonds 2020-2021 128,347,831 228,074 (57,357 ) 128,518,548 $ 178,178,513 $ 254,003 $ (57,357 ) $ 178,375,159 December 31, 2018 Gross Gross Description Effective Maturity Amortized Cost Unrealized Gains Unrealized Losses Fair Value Corporate bonds 2019 $ 154,859,427 — (165,630 ) $ 154,693,797 Government bonds 2019 2,966,262 2,778 — 2,969,040 Corporate bonds 2020 27,029,673 — (54,870 ) 26,974,803 $ 184,855,362 2,778 (220,500 ) $ 184,637,640 The following tables summarize the fair values and levels within the fair value hierarchy in which the fair value measurements fall for assets and liabilities measured on a recurring basis: September 30, 2019 Description Level 1 Level 2 Level 3 Total Assets: Corporate bonds $ — $ 175,377,502 $ — $ 175,377,502 Government bonds $ — $ 2,997,657 $ — $ 2,997,657 December 31, 2018 Description Level 1 Level 2 Level 3 Total Assets: Corporate bonds $ — $ 181,668,600 $ — $ 181,668,600 Government bonds $ — $ 2,969,040 $ — $ 2,969,040 |

Leases [Abstract] | |
Right to Use Assets and Liabilities | 6. Right to Use Assets and Liabilities The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (ROU) assets and operating lease liabilities in the condensed consolidated balance sheets. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The incremental borrowing rate was 5.1%. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Some of the Company’s leases include options to extend or terminate the lease. The Company includes these options in the recognition of the Company’s ROU assets and lease liabilities when it is reasonably certain that the Company will exercise the option. The Company has operating leases for its corporate office and certain equipment, which expire no later than December 31, 2022. The leases have a weighted average remaining term of 3.2 years. Maturities of lease liabilities for the years ending December 31 are: 2019 $ 141,309 2020 764,555 2021 840,498 2022 823,403 Total lease payments 2,569,765 Less: imputed interest (204,976 ) Total $ 2,364,789 The amortization of the ROU assets for the three and nine months ended September 30, 2019 was $140,245 and $506,855, respectively.

Equity | 9. Equity In June 2019, the Company entered into a Stock Purchase Agreement with Bayer AG pursuant to which, in connection with the closing in July 2019, the Company issued and sold to Bayer AG 1,346,313 shares of the Company’s common stock (the Shares) for a contractually stated purchase price of approximately $32.5 million. The value of the shares of the Company’s common stock was based on the average of the Company’s In the Fourth Amendment to the Company’s Incentive Share Plan (the Incentive Plan) adopted in March 2018, the Company was authorized to issue up to an aggregate of 6,199,477 incentive units pursuant to the Incentive Plan. Generally, incentive units were granted at no less than fair value as determined by the board of managers and had vesting periods ranging from one to four years. The Incentive Plan was terminated in September 2018. In September 2018, the Company’s board of directors adopted and the Company’s stockholders approved the 2018 Stock Incentive Plan (the 2018 Plan), which became effective upon the effectiveness of the registration statement on Form S-1 for the Company’s IPO. The number of common shares initially available for issuance under the 2018 Plan is the sum of (1) 4,067,007 shares of common stock; plus (2) the number of shares of common stock (up to 1,277,181) issued in respect of incentive units granted under the Incentive Plan that are subject to vesting immediately prior to the effectiveness of the registration statement that expire, terminate or are otherwise surrendered, cancelled, forfeited or repurchased by the Company at their original issuance price pursuant to a contractual repurchase right; plus (3) an annual increase on the first day of each fiscal year beginning with the fiscal year ending December 31, 2019 and continuing to, and including, the fiscal year ending December 31, 2028, equal to the lowest of 4,989,593 shares of the Company’s common stock, 4% of the number of shares of the Company’s common stock outstanding on the first day of the fiscal year and an amount determined by the Company’s board of directors. The increase in the number of authorized shares for the fiscal year ending December 31, 2019 was 1,293,510. Common shares subject to outstanding equity awards that expire or are terminated, surrendered, or canceled without having been fully exercised or are forfeited in whole or in part shall be available for future grants of awards. During the nine months ended September 30, 2019, the Company granted 1,344,337 stock options to purchase shares of common stock to employees and directors at a weighted average fair value of $12.95 per share. During the nine months ended September 30, 2019, the Company also granted 192,882 restricted stock units, which vest annually over four years. During the nine months ended September 30, 2019, the Company recognized compensation expense of $14,049,075 relating to the issuance of employee and director incentive awards, and at September 30, 2019, there was $17,051,723 of compensation expense that is expected to be amortized over a weighted average period of approximately two years. During the nine months ended September 30, 2019, the Company granted 51,695 stock options to purchase shares of common stock to consultants at a weighted average fair value of $23.89. During the nine months ended September 30, 2019, the Company recognized compensation expense of $1,042,194 relating to incentive share awards for consultants and at September 30, 2019, there was $1,195,887 of compensation expense remaining to be amortized over a weighted average period of approximately 1.3 years. The fair value of the incentive units granted during the nine months ended September 30, 2018 was determined using the Black-Scholes option pricing model with the following assumptions: September 30, 2018 Expected volatility 66.0-71.0% Expected term (years) 5.6-6.1 Risk free interest rate 2.5-2.9% Expected dividend yield 0 % Fair value of underlying common units $1.08-8.48 The fair value of the underlying common units was utilized as the exercise price within the Black-Scholes option pricing model. The fair value of the stock options granted during the nine months ended September 30, 2019 was determined using the Black-Scholes option pricing model with the following assumptions: September 30, 2019 Expected volatility 69.6-70.5% Expected term (years) 5.5-7.0 Risk free interest rate 1.4-2.7% Expected dividend yield 0 % Exercise price $17.29-26.58 Given the Company’s common stock has not been trading for a sufficient period of time, the Company utilizes a collection of volatilities of peer companies to estimate the expected volatility of its common stock. The expected term is calculated utilizing the simplified method.

Income Taxes | 10. Income Taxes The Company’s effective tax rate was 0.0% for the nine months ended September 30, 2019 and 2018. The primary reconciling items between the federal statutory rate of 21.0% for the nine months ended September 30, 2019 and 2018 and the Company’s overall effective tax rate of 0.0% was the effect of equity compensation and the valuation allowance recorded against the full amount of its net deferred tax assets. Valuation allowance is established when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The realization of deferred tax assets depends on the generation of future taxable income during the period in which related temporary differences become deductible. The Company is subject to tax in the U.S. Federal jurisdiction and the states of Connecticut and Massachusetts. The Company pays franchise tax in the states mentioned above due to its loss position. As a result, there is no state income tax provision recorded for the nine months ended September 30, 2019 and 2018. |

Investment in Equity Method Investee | 12. Investment in Equity Method Investee In June 2019, the Company entered into an agreement to establish a joint venture (Commitment Agreement) with Bayer CropScience LP (Bayer LP) to research, develop and commercialize PROTAC targeted protein degraders for applications in the field of agriculture Pursuant to the terms of the Commitment Agreement, the Company made an in-kind intellectual property contribution to Oerth in the form of a license to certain of the Company’s proprietary technology. Bayer LP has made a $56.0 million total cash commitment to Oerth, $16.0 million of which Bayer LP has contributed to Oerth during the quarter ended September 30, 2019, and an in-kind intellectual property contribution. The Company and Bayer LP each hold an ownership interest in Oerth initially representing 50% of the ownership interests. A 15% ownership interest of Oerth is reserved for the future grant of incentive units to employees and service providers of Oerth. Under the joint venture agreement, the Company has no obligation to provide any additional funding and the Company’s ownership interest will not be diluted from future contributions from Bayer LP. The Company has no exposure to future losses of Oerth. The activities of Oerth are controlled by a management board under the joint control of the Company and Bayer LP. As Oerth is jointly controlled by the Company and Bayer LP, the Company accounts for its 50% interest using the equity method of accounting. The Company determined that Oerth is a variable interest entity and, accordingly, the Company has evaluated the significant activities of Oerth under the variable interest entity model and concluded that the significant activities consist primarily of research and development activities and, as the Company does not have the sole power to direct such activities, the Company is not the primary beneficiary. The Company will also provide to Oerth compensated research and development services and administrative services through a separate agreement. The services rendered by the Company during the three months ended September 30, 2019 were insignificant. The Company determined that the fair value of the equity interest it received in Oerth in exchange for the license contributed was $49.4 million. The fair value of Oerth was determined utilizing discounted cash flows based on reasonable estimates and assumptions of cash flows expected from Oerth. The Company recognized revenue of $24.7 million attributable to the license contributed to Oerth and eliminated the remaining $24.7 million which corresponds to the Company’s 50% ownership in Oerth. The Company determined that the amount that was eliminated represents intra-entity profit which should be deferred until realized by Oerth. The deferral will be recognized when Oerth recognizes revenue associated with the license. Until such time, the remaining $24.7 million of revenue is indefinitely deferred and excluded from the results of operations of the Company. The amount recognized as revenue was treated as such because the licensing of its technology in connection with the formation of a joint venture is part of the Company’s major ongoing or central operations, as evidenced by previous licensing agreements. Total operating expenses and net loss of Oerth for the three and nine months ended September 30, 2019 was $49.5 million, which included research and development expenses equal to $49.4 million for the fair value of the Arvinas license acquired. During the three and nine months ended September 30, 2019, the Company recorded equity method losses of $24.7 million based on its proportionate share of ownership. The Company’s initial investment in Oerth was $49.4 million which represented the fair value of shares received in exchange for the contribution of the license. The elimination of the intra-entity profit component of the revenue resulted in a reduction in the balance of the investment in Oerth, bringing its initial carrying value of the investment to $24.7 million. After recognition of its proportionate share of Oerth’s losses for the period the carrying value of the investment as of September 30, 2019 is now $0. |
