CUSIP No. 45665G303

The following constitutes Amendment No. 3 to the Schedule 13D filed by the undersigned (“Amendment No. 3”). This Amendment No. 3 amends the Schedule 13D as specifically set forth herein.

Item 3.Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated to read as follows:

The Shares purchased by BVF, BVF2 and Trading Fund OS were purchased with working capital (which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business) in open market purchases, except as otherwise noted. The aggregate purchase price of the 8,485,575 Shares beneficially owned by BVF is approximately $12,612,545, including brokerage commissions. The aggregate purchase price of the 6,631,136 Shares beneficially owned by BVF2 is approximately $9,791,293, including brokerage commissions. The aggregate purchase price of the 1,254,993 Shares beneficially owned by Trading Fund OS is approximately $1,867,561, including brokerage commissions. The aggregate purchase price of the 1,055,264 Shares held in the Partners Managed Account is approximately $1,444,335, including brokerage commissions.

Item 4.Purpose of Transaction.

Item 4 is hereby amended to add the following:

On January 8, 2020 (the “Closing Date”), the Issuer entered into a funding agreement (the “Funding Agreement”) with Partners and Royalty Security, LLC, a wholly owned subsidiary of Partners, (the “Buyer”) providing for the acquisition by the Buyer of the Issuer’s interest in all royalty payments based on worldwide annual net sales of the compound known as IPI-926, or patidegib (such compound known as the “Licensed Product”) less those royalty payments owed by the Issuer to third parties including Purdue Pharmaceutical Products L.P. (“Purdue”) and Mundipharma International Corporation Limited (“MICL”) (“Third Party Royalty Obligations”) (all royalty payments less Third Party Royalty Obligations, “Royalty”). Such royalties are owed to the Issuer pursuant to that certain License Agreement dated as of June 28, 2013 (as modified, amended, replaced or restated from time to time, the “License Agreement”) by and between the Issuer and PellePharm, Inc. (“PellePharm”).

Pursuant to the Funding Agreement, the Issuer received $20 million (the “Upfront Purchase Price”) less certain transaction expenses. The Issuer transferred to the Buyer (i) the Royalty, (ii) the License Agreement (subject to the Issuer’s rights to milestone payments and rights to equity in PellePharm under the License Agreement), and (iii) certain patent rights established in the Funding Agreement, with (i), (ii), and (iii) together referred to as “Transferred Assets.” The Issuer preserved its rights under the License Agreement to receive shares of common stock issued by PellePharm, subject to the terms and conditions set forth in the License Agreement.

In addition to the Upfront Purchase Price, the Issuer will also be entitled to receive a $5 million milestone payment from the Buyer if PellePharm’s ongoing Phase 3 clinical trial of patidegib topical gel (i) has met its primary endpoint, or (ii) is positively concluded (on the basis of efficacy) at the interim analysis as determined by an independent monitoring committee (the “Milestone Payment”).

Pursuant to the Funding Agreement, within 30 days of the Closing Date, the Issuer and Buyer are required to execute and deliver an escrow agreement under which the parties will establish an escrow account (the “Escrow Account”) to be managed by an escrow agent chosen by mutual agreement of the parties (the “Escrow Agent”). All amounts owed by PellePharm to the Issuer under the License Agreement are required to be deposited into the Escrow Account. Amounts paid into the Escrow Account by PellePharm that correspond to Royalties will be paid by the Escrow Agent to the Buyer. Amounts paid into the Escrow Account by PellePharm that do not correspond to Royalties, including Third Party Royalty Obligations and milestone amounts payable by PellePharm under the License Agreement, will be paid by the Escrow Agent to the Issuer. The Issuer will not be independently obligated for the Royalties owed to Buyer under the License Agreement and has no liability for non-payment of the Royalties under the License Agreement as a result of the insolvency, bankruptcy, inability to pay, or other credit event of PellePharm.

CUSIP No. 45665G303

Issuer’s Option to Repurchase

If the Shares achieve a 20-day volume-weighted average price on the Nasdaq Global Select Market equal to or greater than $5.00 per share (adjusted for any stock splits, reverse splits, or similar arrangements) (the “Purchase Threshold”), the Issuer has an option to purchase from Partners 100% of the outstanding equity interests of the Buyer, whose sole assets are expected to be Transferred Assets (the “Option”) upon or after any time at which the Purchase Threshold has been achieved. To exercise the Option, the Issuer must deliver to Partners (a) notice (the “Option Notice,” with the date on which delivery of the Option Notice is given, the “Option Notice Date”) of its election to do so prior to the earliest to occur of: (i) the occurrence of certain trigger events identified in the Funding Agreement, including a material failure of the Issuer to perform certain covenants, a failure by the Issuer to cause the Funding Agreement and related agreements to remain in full force and effect, a deficiency in any security interest purported to be created by the Funding Agreement resulting from an act or omission of the Issuer, or another insolvency event of the Issuer (upon the expiration of any applicable cure period) (each, an “Issuer Trigger Event”), (ii) the third anniversary of the Closing Date, or (iii) the date immediately prior to a change of control of the Issuer (together, the “Option Expiration Date”), and (b) within ten (10) business days after the Option Notice is deemed delivered to Partners (the “Repurchase Date”), an amount equal to the Upfront Purchase Price plus the Milestone Payment, if and when paid to the Issuer, plus the Option Premium, defined below, less the aggregate amount of all Royalty payments received by Buyer as of the Option Exercise Date. The exercise of the Option may only occur if the Shares maintain a 20-day volume-weighted average price on Nasdaq of $5.00 per share (adjusted for any stock splits, reverse splits, or similar arrangements) on each trading day between the Option Notice Date and the Repurchase Date “Option Premium” means an amount accruing daily on (x) the Upfront Purchase Price plus the Milestone Payment, if and when paid to Issuer as of such day, less (y) the aggregate amount of all Royalty payments received by Buyer as of such day, at a rate of 10% per annum, compounded quarterly. For purposes of calculating the Option Premium, in the event of an Issuer Trigger Event, the rate of accrual following the occurrence of such Issuer Trigger Event shall be increased to 20% per annum.

Potential Future Warrants

As part of the consideration to Partners for providing the funding under the Funding Agreement, the Issuer agreed to issue warrants in the future to Partners if the Issuer issued and sold Shares to third parties above a specified threshold and below a specified price.

The Funding Agreement provides that, for so long as the Issuer has not exercised its Option, (a) if, during the 36-month period following the Closing Date, the Issuer issues and sells in the aggregate more than 8,554,345 Shares (including options, warrants, convertible stock, convertible debt and other common-stock equivalents) (the “Warrant Threshold”), and (b) any shares are issued in excess of the Warrant Threshold with consideration to the Issuer of less than $3.75 per share (as adjusted for any stock splits, reverse stock splits or other similar recapitalization events) (the “Threshold Price”), then the Issuer shall be obligated to issue to Partners warrants to purchase a number of Shares equal to 50% of the number of Shares issued and sold by the Issuer in excess of the Warrant Threshold, with any such Warrants having an exercise price equal to 1.5 times the price per share of such shares issued in excess of the Warrant Threshold.

Certain issuances of Shares are excluded from the calculation of the Warrant Threshold, including the grant, exercise, or vesting of options or awards granted pursuant to the Issuer’s stock incentive plans or stock purchase plans. Once the Warrant Threshold has been met, the requirement to issue warrants does not apply to certain issuances of Shares, including the grant, exercise, or vesting of options or awards granted pursuant to the Issuer’s stock incentive plans or stock purchase plans and, subject to certain limitations, the issuance of Shares in connection with a transaction with an unaffiliated third party that includes a debt financing or a bona fide commercial relationship or any acquisition of assets, merger with, or acquisition of another entity.

10

CUSIP No. 45665G303

Servicing Requirements

The Issuer, on behalf of the Buyer, will perform certain servicing, management and administrative functions with respect to the Transferred Assets, subject to standards set forth in the Funding Agreement. The Issuer may resign as Servicer, and the Buyer may, under certain conditions, remove the Issuer as servicer and retain a replacement third-party servicer. The Issuer will be paid by the Buyer a servicing fee equal to $1,000 per year in arrears.

Additional Customary Terms

The Funding Agreement contains other customary terms and conditions, including representations and warranties, conditions precedent, indemnities and covenants, including covenants that, among other things, require the Issuer to provide certain information to the Buyer with respect to the License Agreement and the Licensed Product and to cooperate with the Buyer, at the Buyer’s expense, to take certain actions under the License Agreement and otherwise with respect to the Licensed Product to protect the Buyer’s rights to receive the Royalty payments. These covenants are subject to a number of important exceptions and qualifications.

In addition to exercise of the Option, the Funding Agreement may be terminated by mutual written agreement of the Issuer and the Buyer.

The foregoing description of the Funding Agreement is qualified in its entirety by reference to the Funding Agreement, which the Issuer intends to file as an exhibit to the Issuer’s Annual Report on Form 10-K for the fiscal year ended December 31, 2019.
