Infinity Provides Company Update and Reports Third Quarter 2017 Financial Results

CAMBRIDGE, Mass., Nov. 7, 2017 /PRNewswire/ --Infinity Pharmaceuticals Inc. (NASDAQ: INFI) today announced its third quarter 2017 financial results and provided an update on the company, including its progress with IPI-549, an oral immuno-oncology product candidate that selectively inhibits phosphoinositide-3-kinase-gamma (PI3K-gamma). Infinity is evaluating IPI-549 as a monotherapy and in combination with Opdivo^® (nivolumab), a PD-1 immune checkpoint inhibitor, in a four-part Phase 1/1b study in patients with advanced solid tumors. In preclinical studies, IPI-549 reprograms macrophages from a pro-tumor, M2, to an anti-tumor, M1, phenotype and is able to overcome resistance to checkpoint inhibition as well as to enhance the activity of checkpoint inhibitors.^1,2 IPI-549 is believed to be the only selective PI3K-gamma inhibitor in clinical development.

On November 10, 2017, a late-breaking abstract summarizing data from the recently completed monotherapy dose-escalation component of the study will be presented at the 2017 Society for Immunotherapy of Cancer (SITC) Annual Meeting taking place in National Harbor, MD. The presentation, which will be made during an oral session on new agents, will include an analysis of the safety, activity, pharmacokinetics and pharmacodynamics of IPI-549 in 19 patients who received once daily (QD) doses of IPI-549 ranging from 10 mg to 60 mg. Initial translational data describing how inhibiting PI3K-gamma may elicit an immune response and identifying potential biomarkers of immune response will also be presented. In August, Infinity announced that the company designated the 60 mg QD dose for evaluation in the monotherapy expansion component of the study, which is now under way.

“We are looking forward to sharing the full data from the completed monotherapy dose escalation component of our study later this week at the SITC Annual Meeting. In addition to reporting on the safety and activity of IPI-549 monotherapy, for the first time we will present initial translational data from patients treated with IPI-549 as a monotherapy that can help us better understand how IPI-549 may activate an immune response,” stated Adelene Perkins, Infinity’s chair and chief executive officer. “Patient enrollment in the monotherapy expansion component of the study is progressing very well, and we expect to initiate the combination expansion portion of the study by the end of this year, positioning us for data readouts from the monotherapy expansion cohort as well as data from the combination dose escalation and disease-specific expansion cohorts, all in the first half of 2018.”

The Phase 1/1b study of IPI-549 is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and activity of IPI-549 as a monotherapy and in combination with the approved dose of Opdivo in approximately 200 patients with advanced solid tumors. The study includes four components: monotherapy dose escalation, combination therapy dose escalation, monotherapy expansion and combination expansion. The combination expansion will include multiple cohorts designed to evaluate IPI-549 in patients with specific types of cancer, including patients with non-small cell lung cancer (NSCLC), melanoma, and head and neck squamous cell carcinoma (HNSCC) whose tumors show initial resistance or subsequently develop resistance to immune checkpoint blockade therapy. Additionally, the combination expansion component will also evaluate a cohort of patients with triple negative breast cancer (TNBC) who have not been previously exposed to anti-PD-1 or anti-PD-L1 therapy.

Based on progress made during 2017, Infinity expects to achieve the following IPI-549 data milestones in 2018:

• Report data from the monotherapy expansion component of the study in the first half of 2018
• Report data from the combination dose-escalation component of the study in the first half of 2018
• Report initial data from the combination expansion component of the study in the first half of 2018, with more mature data from the combination expansion in the second half of 2018

“We are also focused on maintaining strong fiscal discipline and anticipate that we have cash runway into the first quarter of 2019, allowing us to generate safety and activity data on all four components of our Phase 1/1b study of IPI-549,” commented Lawrence Bloch, M.D., J.D., president of Infinity. “We also have the potential to receive a future $22 million payment from Verastem upon the first regulatory approval of duvelisib, which we out-licensed in 2016, that could further strengthen our financial profile.”

Recent Corporate Developments

• $6.0 million payment received from Verastem: In October, Infinity received a $6.0 million cash payment from Verastem, Inc. The payment was made following the determination that the Phase 3 DUO clinical study evaluating the efficacy and safety of duvelisib in patients with relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma met certain pre-specified criteria at completion. Infinity out-licensed duvelisib to Verastem in November 2016.

  Verastem recently provided guidance that it plans to submit a new drug application for duvelisib in the first quarter of 2018. Infinity is entitled to receive a $22 million payment from Verastem upon the first regulatory approval for duvelisib inside or outside the U.S.

Recent Clinical Developments

• IPI-549 selected for an oral presentation at SITC Annual Meeting: In October, Infinity announced that a late-breaking abstract describing new data for IPI-549 was selected for presentation during an oral session on new agents at the SITC Annual Meeting. The abstract, “Monotherapy dose escalation clinical and translational data from first-in-human study in advanced solid tumors of IPI-549, an oral, selective, PI3K-gamma inhibitor targeting tumor macrophages” (Abstract O43), will be presented on Friday, November 10, 2017, from 2:15 p.m. - 2:30 p.m. ET. The lead author and presenter is David Hong, M.D., Deputy Chair, Department of Investigational Cancer Therapeutics, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center, Houston, TX. An identically titled accompanying poster will also be presented on Friday, November 10, 2017, from 12:30 p.m. - 2:00 p.m. ET and 6:30 p.m. - 8:00 p.m. ET.

  Additionally, a clinical trials in progress poster, “Phase 1/1b, first-in-human study of the PI3K-gamma inhibitor IPI-549 as monotherapy and combined with nivolumab in patients with advanced solid tumors” (Abstract P219), will be presented on Friday, November 10, 2017, from 12:30 p.m. - 2:00 p.m. ET and 6:30 p.m. - 8:00 p.m. ET. The lead author on the poster is Antoni Ribas, M.D., Ph.D., Parker Institute Center Director at the University of California, Los Angeles (UCLA).

  Infinity will host a reception for investors and analysts on Friday, November 10, 2017, from 6:00 a.m. to 8:00 a.m. ET to discuss the clinical development of IPI-549, including a review of data from the ongoing clinical study. The presentation portion of the reception will be webcast live beginning at 6:30 a.m. ET. The webcast and accompanying slides will be available in the “investors/media” section of the company’s website, www.infi.com. A replay of the event will also be available.

• Expanded clinical collaboration with Bristol-Myers Squibb: In September, Infinity announced that it expanded its existing clinical collaboration with Bristol-Myers Squibb evaluating IPI-549 in combination with Opdivo to include patients with TNBC who have not been previously exposed to anti-PD-1 or anti-PD-L1 therapy. The TNBC cohort will be part of the combination expansion component of the Phase 1/1b study.

• Phase 1/1b study of IPI-549 advancing: The company is continuing to advance the Phase 1/1b study of IPI-549 both as a monotherapy and in combination with Opdivo in patients with solid tumors. Infinity has completed an evaluation of escalating monotherapy doses of IPI-549 ranging from 10 mg QD to 60 mg QD and selected the 60 mg dose for evaluation in the monotherapy expansion component of the study. Dose escalation evaluating IPI-549 40 mg QD in combination with Opdivo is ongoing, and Infinity expects to initiate the combination expansion component of the study by the end of 2017.

Third Quarter 2017 Financial Results

• At September 30, 2017, Infinity had total cash, cash equivalents and available-for-sale securities of $55.6 million, compared to $66.2 million at June 30, 2017. The September 30, 2017 cash and investments balance excludes the $6.0 million payment from Verastem, which Infinity received in October 2017.
• Revenue for the third quarter of 2017 was $6.0 million, all of which related to the amounts due from Verastem for the DUO study meeting the pre-specified criteria at completion. Infinity did not record any revenue during the third quarter of 2016.
• Research and development (R&D) expense for the third quarter of 2017 was $9.3 million, compared to $12.8 million for the same period in 2016. The decrease in R&D expense was related to the company’s 2016 restructuring activities, partially offset by the $6.0 million convertible note issued to Takeda in exchange for eliminating Infinity’s royalty obligation to Takeda for selective inhibitors of PI3K gamma, including IPI-549.
• General and administrative (G&A) expense was $4.5 million for the third quarter of 2017 compared to $7.1 million for the same period in 2016. The decrease in G&A expense was primarily due to the company’s 2016 restructuring activities.
• Net loss for the third quarter of 2017 was $7.1 million, or a basic and diluted loss per common share of $0.14, compared to net loss of $19.5 million, or a basic and diluted loss per common share of $0.39, for the third quarter of 2016.

Cash and Investments Outlook

Infinity’s 2017 financial outlook remains as follows:

• Net loss: Infinity expects net loss for 2017 to range from $40 million to $50 million.
• Cash and Investments: Infinity expects to end 2017 with a cash, cash equivalents and available-for-sale securities balance ranging from $40 million to $50 million.

Based on its current operational plans, Infinity expects that its cash, cash equivalents and available-for-sale securities at September 30, 2017, will be adequate to satisfy the company’s capital needs into the first quarter of 2019. The company’s financial outlook excludes additional funding or business development activities.

About the IPI-549 and the Ongoing Phase 1 Study
IPI-549 is an investigational, orally administered immuno-oncology development candidate that selectively inhibits PI3K-gamma. In preclinical studies, IPI-549 reprograms macrophages from a pro-tumor, M2, to an anti-tumor, M1, phenotype and is able to overcome resistance to checkpoint inhibition as well as to enhance the activity of checkpoint inhibitors.^1,2 As such, IPI-549 may have the potential to treat a broad range of solid tumors and represents a potentially complementary approach to restoring anti-tumor immunity in combination with other immunotherapies such as checkpoint inhibitors.

The ongoing Phase 1/1b study being conducted by Infinity is designed to evaluate the safety, tolerability, activity, pharmacokinetics and pharmacodynamics of IPI-549 as a monotherapy and in combination with Opdivo in approximately 200 patients with advanced solid tumors.³ The four-part study includes monotherapy and combination dose-escalation components, in addition to monotherapy expansion and combination expansion components. Patient enrollment is complete in monotherapy dose-escalation, and monotherapy expansion is ongoing. Combination dose-escalation is also ongoing, and combination expansion is expected to begin by the end of 2017.

The combination expansion component includes multiple cohorts designed to evaluate IPI-549 in patients with specific types of cancer, including patients with non-small cell lung cancer (NSCLC), melanoma, and head and neck squamous cell carcinoma (HNSCC) whose tumors show initial resistance or subsequently develop resistance to immune checkpoint blockade therapy. This combination expansion component will now also add a cohort of patients with triple negative breast cancer (TNBC) who have not been previously exposed to immune checkpoint blockade therapy. Although there has been great progress in the treatment of cancer, there remains a need for additional treatment options. NSCLC, melanoma, HNSCC and TNBC account for more than 22 percent of all new cancer cases in the U.S.^4,5

IPI-549 is an investigational compound and its safety and efficacy has not been evaluated by the U.S. Food and Drug Administration or any other health authority.
