- Dr. Samuel Agresta Appointed as Chief Medical Officer -
- More Mature Data from Combination Expansion Cohorts of the On-Going IPI-549 MARIO-1 Phase 1/1b Study Expected in the Second Half of 2018 -

CAMBRIDGE, Mass., Aug. 7, 2018 /PRNewswire/ -- Infinity Pharmaceuticals, Inc. (NASDAQ: INFI) today announced its second quarter 2018 financial results and provided an update on the company, including its progress with IPI-549, a first-in-class oral immuno-oncology product candidate that selectively inhibits phosphoinositide-3-kinase-gamma (PI3K-gamma) and targets immune-suppressive tumor macrophages/myeloid-derived suppressor cells (MDSCs).

"We are particularly pleased to welcome Sam Agresta to the Infinity team as Chief Medical Officer. Sam brings extensive experience in novel oncology drug development, having led the recent approvals of Agios's two targeted therapies based on compelling Phase 1 data," said Adelene Perkins, Chief Executive Officer and Chair of Infinity Pharmaceuticals. "We continue to be encouraged by our progress in all aspects of our business. Building on the datasets we presented at the recent American Society of Clinical Oncology (ASCO) Annual Meeting, including showing that IPI-549 was well-tolerated, clinically active and on-mechanism as a monotherapy and in combination with nivolumab, we look forward to presenting more mature data from the combination expansion cohorts in the second half of this year. We are also enthusiastic about partnering with Arcus and testing IPI-549 in combination with its very promising novel agents, in a new collaboration we established in June."

Infinity is evaluating IPI-549 as a monotherapy and in combination with Opdivo® (nivolumab), a PD-1 immune checkpoint inhibitor, in collaboration with Bristol-Myers Squibb, in the MARIO-1 Phase 1/1b study in approximately 200 patients with advanced solid tumors. In addition, Arcus Biosciences will initiate two triple combinations investigating IPI-549 with their dual adenosine receptor antagonist, AB928, anti-PD-1 antibody, AB122, and chemotherapy in triple negative breast cancer and ovarian cancer. One triple combination therapy will evaluate IPI-549 in combination with AB928 and AB122 and the second will evaluate IPI-549 in combination with AB928 and chemotherapy, with topline data expected in 2019.

Recent developments include the following:


  • Continued Progress with the MARIO-1 Phase 1/1b Study of IPI-549: The monotherapy and combination dose-escalation portions of this study have been completed. Enrollment is complete in the mesothelioma combination expansion cohort and is ongoing for the other five disease-specific combination expansion cohorts currently underway, as well as for the seventh combination expansion cohort of patients pre-selected for having high baseline blood levels of myeloid derived suppressor cells (MDSCs), which began enrolling patients in May 2018.

Second Quarter 2018 Financial Results

  • At June 30, 2018, Infinity had total cash, cash equivalents and available-for-sale securities of $49.2 million, compared to $47.8 million at March 31, 2018.
  • R&D expense for the second quarter of 2018 was $3.7 million, compared to $3.9 million for the same period in 2017. The decrease in R&D expense was primarily due to a reduction in bonus and stock compensation offset by an increase in clinical development expense for IPI-549.
  • General and administrative expense was $3.4 million for the second quarter of 2018, compared to $6.2 million for the same period in 2017. The decrease in G&A expense was primarily due to a reduction in bonus and stock compensation.
  • Net loss for the second quarter of 2018 was $7.0 million, or a basic and diluted loss per common share of $0.12, compared to a net loss of $17.0 million, or a basic and diluted loss per common share of $0.34 for the same period in 2017.

Financial Outlook
Infinity's 2018 financial guidance is:

  • Net Loss: Infinity expects net loss for 2018 to range from $35 million to $45 million.
  • Cash and Investments: Infinity expects to end 2018 with a year-end cash, cash equivalents and available-for-sale securities balance ranging from $15 million to $25 million.
  • 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 through the third quarter of 2019. Infinity's financial guidance excludes additional funding or business development activities and does not include the potential $22 million payment from Verastem upon the first regulatory approval of duvelisib, or a potential $2 million payment from PellePharm, a private company, upon initiation of a Phase 3 study for the hedgehog inhibitor program, which Infinity licensed to PellePharm in 2013. Verastem announced that its New Drug Application for duvelisib was accepted by the U.S. Food and Drug Administration (FDA) and that it was given priority review with an FDA action date of October 5, 2018. With the potential Verastem payment, Infinity expects that its cash runway would extend into 2020.

About IPI-549 and the Ongoing Phase 1/1b Study
IPI-549 is an investigational first-in-class, oral, immuno-oncology product candidate targeting tumor-associated myeloid cells through selective phosphoinositide-3-kinase-gamma (PI3K-gamma) inhibition, thereby reducing pro-tumor macrophage function and increasing anti-tumor macrophage function. In preclinical studies, IPI-549 demonstrated the ability to reprogram macrophages from a pro-tumor (M2), immune suppressive function, to an anti-tumor (M1) immune activating function and enhance the activity of, and overcome resistance to, checkpoint inhibitors.1,2 As such, IPI-549 may have the potential to treat a broad range of solid tumors and represents a potentially additive or synergistic 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 study includes monotherapy and combination dose-escalation components, in addition to monotherapy expansion and combination expansion components. The monotherapy dose-escalation and expansion components are complete. The combination dose-escalation component is also complete, and combination expansion cohorts are enrolling.

The combination expansion component of the study 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 cancer whose tumors show initial resistance or initially respond to but subsequently develop resistance to immune checkpoint blockade therapy. The combination expansion component also includes a cohort of patients with triple negative breast cancer (TNBC) who have not been previously treated with immune checkpoint blockade therapy, a cohort of patients with mesothelioma, a cohort of patients with adrenocortical carcinoma and a cohort of patients with high baseline blood levels of MDSCs.

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.
