Infinity Pharmaceuticals, Inc. (NASDAQ: INFI) today announced its first quarter 2019 financial results and provided an update on the company, including its progress in expanding the breadth and depth of the development of IPI-549 in over 500 patients. IPI-549 is a first-in-class oral immuno-oncology product candidate that targets immune-suppressive tumor-associated myeloid cells through selective phosphoinositide-3-kinase-gamma (PI3K-gamma) inhibition. In the first quarter of 2019, Infinity entered into a clinical collaboration with Roche/Genentech moving into front-line triple negative breast cancer (TNBC) and renal cell cancer (RCC) with MARIO-3. In the first quarter of 2019, Infinity also closed the Copiktra royalty monetization for $20.9M in net proceeds and earned a $2M milestone from PellePharm, providing non-dilutive capital to fund the expanded development of IPI-549, including MARIO-3.

"Shareholder value creation will be driven by the generation of compelling clinical data with IPI-549, funded with dilution-sensitive capital, and we are pleased to have made important progress on both of these fronts in the first quarter of this year. We continue to advance IPI-549 and remain focused on achieving our key clinical milestones for 2019," said Adelene Perkins, Chief Executive Officer and Chair of Infinity Pharmaceuticals. "We are studying IPI-549 in earlier lines of therapy, new indications and novel, potentially transformative immuno-oncology combinations in 2019."

Anticipated Milestones in 2019: Expanding Depth and Breadth of IPI-549 Development

2Q2019

• Initiate MARIO-275, a Phase 2 study of IPI-549 in combination with Opdivo®, in second-line immuno-oncology (I/O) naïve urothelial cancer patients, in collaboration with BMS

2H2019

• Initiate MARIO-3, a Phase 2 study of novel triple combination front-line therapy, in clinical collaboration with Roche/Genentech:
  • IPI-549 in combination with Tecentriq® and Abraxane® in TNBC
  • IPI-549 in combination with Tecentriq and Avastin® in RCC
• Complete enrollment of MARIO-1 combination expansion cohorts including:
  • Augmented melanoma expansion cohort (n=40)
  • TNBC expansion cohort (n=29)
• Advance into novel triple combination therapies beyond checkpoint inhibitors: initiate triple therapy (IPI-549+AB928+Abraxane) in previously treated advanced TNBC in collaboration with Arcus Biosciences

First Quarter 2019 Financial Results

• At March 31, 2019, Infinity had total cash, cash equivalents and available-for-sale securities of $70.5 million, compared to $58.6 million at December 31, 2018.
• Infinity recognized the $30 million gross proceeds from the Copiktra royalty monetization as a liability, net of transaction costs, as of March 31, 2019. We are amortizing the liability to non-cash interest expense, and we will continue to recognize the royalty revenue that Verastem pays to HealthCare Royalty Partners III, L.P. (HCR) as non-cash royalty revenue. We shared 25% of the proceeds, net of expenses, under the HCR agreement with Takeda. In addition, we will pay to Takeda 25% of royalties that, but for the HCR agreement, would have been payable to us by Verastem during the term of the HCR agreement.
• Revenue during the first quarter of 2019 was $2.1 million, which primarily relates to the achievement of a $2.0 million milestone from PellePharm for the initiation of a Phase 3 study investigating patidegib (a hedgehog pathway inhibitor) in patients with Gorlin Syndrome. We did not have any revenue for the same period in 2018.
• R&D expense for the first quarter of 2019 was $5.8 million, compared to $5.9 million for the same period in 2018.
• General and administrative expense was $3.4 million for the first quarter 2019, compared to $3.6 million for the same period in 2018.
• Royalty expense for the first quarter of 2019 was $6.8 million, which primarily relates to our payment to Takeda in relation to the monetization of Copiktra royalties.
• Net loss for the first quarter of 2019 was $13.7 million, or a basic and diluted loss per common share of $0.24, compared to a net loss of $9.5 million, or a basic and diluted loss per common share of $0.18 for the same period in 2018.

2019 Updated Financial Guidance

• Net Loss: Infinity expects net loss for 2019 to range from $40 million to $50 million including the Copiktra royalty monetization.
• Cash and Investments: Infinity expects to end 2019 with a year-end cash, cash equivalents and available-for-sale securities balance ranging from $40 million to $50 million including the Copiktra royalty monetization.
• Cash Runway: Based on its current operational plans, Infinity expects that its existing cash, cash equivalents and available-for-sale securities will be adequate to satisfy the company's capital needs into 2H 2020. Infinity's financial guidance excludes additional funding or business development activities and excludes the potential monetization of future milestones and/or royalties payments from PellePharm, a private company, to whom Infinity licensed patidegib in 2013.

About Infinity and IPI-549

Infinity is an innovative biopharmaceutical company dedicated to advancing novel medicines for people with cancer. Infinity is advancing IPI-549, a first-in-class, oral immuno-oncology development candidate that selectively inhibits PI3K-gamma, in multiple clinical studies. MARIO-1 is an ongoing Phase 1/1b study evaluating IPI-549 as a monotherapy and in combination with Opdivo (nivolumab) in approximately 220 patients with advanced solid tumors including patients refractory to anti-PD-1 therapy. Infinity intends to initiate MARIO-275, a global, randomized, combination study of IPI-549 combined with Opdivo in I/O naïve urothelial cancer patients in 2Q19, as well as to initiate MARIO-3, the first IPI-549 combination study in front-line advanced cancer patients in 2H19. MARIO-3 will evaluate IPI-549 in combination with Tecentriq and Abraxane in front-line TNBC and in combination with Tecentriq and Avastin in front-line RCC. With the addition of MARIO-275 and MARIO-3 to the ongoing MARIO-1 study, Infinity will be evaluating IPI-549 in the anti-PD-1 refractory, I/O-naïve and front-line settings in a total of ~500 patients.
