CAMBRIDGE, Mass., Jan. 8, 2018 /PRNewswire/ -- Infinity Pharmaceuticals,Inc. (NASDAQ: INFI) today announced the achievement of four development milestones for IPI-549, a first-in-class, oral, immuno-oncology product candidate targeting tumor-associated myeloid cells through selective phosphoinositide-3-kinase-gamma (PI3K-gamma)
Infinity also provided financial guidance for 2018 and outlined anticipated 2018 milestones for the development of IPI-549. During the year, the company expects to make substantial progress with the Phase 1/1b clinical study of IPI-549, which is designed to evaluate IPI-549 both as a monotherapy and in combination with Opdivo. Infinity plans to report data from the monotherapy expansion and combination dose escalation components and initial data from the combination expansion component of the Phase 1/1b study of IPI-549 with Opdivo in the second quarter of 2018. In the second half of 2018, Infinity expects to report more mature clinical data from the combination expansion component of the study including translational insights from paired tumor biopsies across multiple diseases.
"2018 will be a decisive year for both Infinity and IPI-549, as we look forward to reporting maturing data from the Phase 1/1b trial both in monotherapy and in combination with Opdivo at several medical meetings throughout the year, which will help to define our development and regulatory strategy for this first-in-class product candidate," stated Adelene Perkins, Infinity's chair and chief executive officer. "IPI-549 represents a unique approach to targeting tumors through its effects on myeloid cells within the tumor microenvironment, and we are very pleased with the data to date. There is a significant need for better treatment options for patients, especially for patients who do not respond to, or develop resistance to, existing immunotherapies, as well as for types of cancer where there is limited benefit from treatment with checkpoint inhibitors. We look forward to presenting updates throughout 2018 from our Phase 1/1b clinical trial."
"As the majority of patients treated with IPI-549 monotherapy have advanced forms of cancer and received several therapies prior to enrollment in this study, it's very encouraging to see single-agent activity, including a patient with a partial response who has remained on treatment for over a year and continues on study today," said Dr. David Hong from MD Anderson Cancer Center, Deputy Chair of the Department of Investigational Cancer Therapeutic. "IPI-549 has also been well tolerated with a favorable safety profile."
Infinity's chair and chief executive officer, Adelene Perkins, will discuss the company's continued execution on its corporate strategy and 2018 priorities as part of a podium presentation at the 36th Annual J.P. Morgan Healthcare Conference on Thursday, January 11, at 9:30 a.m. PST (12:30 p.m. EST). The presentation will be webcast on Infinity's website, www.infi.com.
Anticipated Milestones in 2018 During 2018, Infinity expects to achieve the following IPI-549 data milestones:
2018 Financial GuidanceInfinity ended 2017 with approximately $57.6 million in cash and investments (unaudited) and plans to report its fourth quarter and full-year 2017 financial results in March. The company is providing the following financial guidance today:
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. Verastem has provided its expectation that it plans to submit a New Drug Application to the U.S. Food and Drug Administration for duvelisib in the first quarter of 2018.
About IPI-549IPI-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 reprograms macrophages from a pro-tumor (M2), immune suppressive function, to an anti-tumor (M1) immune activating function and can enhance the activity of, and overcome resistance to, checkpoint inhibitors.4 5 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.6 The four-component study includes monotherapy and combination dose-escalation components, in addition to monotherapy expansion and combination expansion components. The monotherapy dose-escalation component is complete and the monotherapy expansion component has been fully enrolled. The combination dose-escalation component is also complete, and combination expansion cohorts are open to enrollment.
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 squamous cell carcinoma (HNSCC) 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 levels of MDSCs.
IPI-549 is an investigational compound, and its safety and efficacy have not been evaluated by the U.S. Food and Drug Administration or any other health authority.
