"Infinity had a very successful 3rd quarter reaching major clinical milestones with eganelisib and welcoming two outstanding R&D executives to our management team," said Adelene Perkins, Chief Executive Officer and Chair, Infinity Pharmaceuticals. "In particular, data presented in July from MARIO-3 and MARIO-275 show that eganelisib, with its unique role in reprogramming macrophages, increases the effectiveness of current checkpoint inhibitors and improves patient outcomes across multiple indications and treatment settings. These data show that eganelisib has the potential to drive the next generation of cancer immuno-therapy."
"The data on prolonged progression-free survival in metastatic triple negative breast cancer, increased overall survival in metastatic urothelial cancer, and translational evidence of modulation of the tumor microenvironment highlight the broad potential of eganelisib to improve immune checkpoint inhibitor-based treatments for patients regardless of PD-L1 status. This is particularly meaningful for PD-L1 negative 1L mTNBC patients for whom no checkpoint inhibitors have been approved and for PD-L1 negative mUC patients for whom checkpoint inhibitors are less effective," said Dr. Robert Ilaria, Chief Medical Officer, Infinity Pharmaceuticals. "We look forward to presenting a TNBC update at SABCS in December for which we are especially interested in seeing if the encouraging PFS data presented this summer is maintained in the maturing data set and to providing an update on eganelisib in UC in our January 5th guidance for 2022."
Recent Updates:
MARIO-3: Updated data was presented from 43 patients (43 patients evaluable for safety and 38 patients evaluable for efficacy) were presented on July 27, 2021, from the Company’s ongoing Phase 2 study evaluating eganelisib in a novel triple combination with Tecentriq (atezolizumab) and Abraxane (nab-paclitaxel) in unresectable locally advanced or metastatic triple negative breast cancer (TNBC). Updated safety and efficacy data will be presented at the San Antonio Breast Cancer Symposium (SABCS) Annual Meeting, December 7-10, 2021.
Encouraging efficacy data presented on July 27, 2021, suggest the addition of eganelisib to Tecentriq and Abraxane has the potential to extend progression-free survival regardless of PD-L1 status.
86.8% (33/38) of evaluable patients demonstrated tumor reduction, with the majority of patients still on treatment.
The addition of eganelisib appears to extend progression-free survival (PFS) in both PD-L1(+) and PD-L1(-) patients relative to the Tecentriq and Abraxane combination from the benchmark IMpassion130 study.
In PD-L1(-) patients, median PFS was 7.3 months (3.5, NA) in MARIO-3, compared to median PFS of 5.6 months for Tecentriq and Abraxane in IMpassion130. There are currently no approved checkpoint inhibitor regimens, including the combination of Tecentriq and Abraxane, for PD-L1 (-) 1L mTNBC patients.
In PD-L1(+) patients, median PFS was 11.2 months (5.3, 11.2) in MARIO-3 compared to 7.5 months for Tecentriq and Abraxane in IMpassion130. The Tecentriq and Abraxane combination is approved in PD-L1(+) 1L mTNBC patients in over 70 countries.
Overall safety in MARIO-3 was consistent with the safety profile of eganelisib and the published safety profile of the marketed products Tecentriq and Abraxane, and no new safety signals were observed. The most common ≥GR3 treatment-related adverse events (AEs) were hepatic AEs (18%); neutropenia AEs (16%); skin AEs (12%); fatigue (6%); peripheral sensory neuropathy (6%); and diarrhea (6%).
MARIO-275: Updated data on 49 patients were presented on July 27, 2021, from the Company’s randomized, placebo-controlled Phase 2 study evaluating the efficacy and safety of eganelisib in combination with Opdivo (nivolumab) in platinum-refractory, I/O naïve patients with locally advanced or metastatic urothelial cancer (UC).
Median overall survival (mOS) in the intent to treat population was 15.4 months (6.2, NE) on the eganelisib plus Opdivo arm compared to 7.9 months (2.3, NE) on the Opdivo control arm (hazard ratio of 0.62 (0.28, 1.36)), reflecting a 38% lower probability of death.
Median overall survival was equally strong in PD-L1(-) patients with a hazard ratio of 0.60 (0.21, 1.71), reflecting a 40% lower probability of death.
The most common ≥Grade 3 treatment-related adverse events (AEs) were, across all doses, all causality, anemia (12.1%), and hepatic AEs including hepatotoxicity (15.2%), increased ALT (12.1%) and increased AST (12.1%) with no Hy’s Law. No Grade 5 hepatic AEs were reported.
Corporate:
Appointed Stéphane Peluso, Ph.D., as Chief Scientific Officer, joining Infinity from Ipsen.
Appointed Robert Ilaria, Jr., M.D. as Chief Medical Officer, joining Infinity from Bristol Myers Squibb/Celgene.
Appointed Brian Schwartz, M.D., to Board of Directors, transitioning from consulting Chief Physician to the Board.
Third Quarter 2021 Financial Results:
At September 30, 2021, Infinity had total cash, cash equivalents and available-for-sale securities of $90.1 million, compared to $97.3 million at June 30, 2021.
Research and development expense for the third quarter of 2021 was $7.1 million, compared to $6.1 million in the same period in 2020. The increase is primarily related to an increase in compensation related expenses and clinical development expenses to support continued development of eganelisib.
General and administrative expense was $3.8 million for the third quarter of 2021, compared to $2.9 million for the same period in 2020. The increase in G&A expense is primarily due to an increase in consulting expenses, professional services and stock compensation.
Net loss for the third quarter of 2021 was $10.7 million, or a basic and diluted loss per common share of $0.12, compared to a net loss of $9.5 million, or a basic and diluted loss per common share of $0.16 in the same period in 2020.
Financial Outlook: Infinity’s 2021 financial guidance remains as follows:
Net Loss: Infinity expects net loss for 2021 to range from $40 million to $50 million.
Cash and Investments: Infinity expects to end 2021 with a year-end-cash, cash equivalents and available for sale securities balance ranging from $70 million to $80 million. Infinity’s financial guidance does not include additional funding or business development activities.
