Strong financial position with $177 million in cash and cash equivalents as of March 31, 2022, with cash runway anticipated into first half of 2024

WALTHAM, Mass., May 12, 2022 (GLOBE NEWSWIRE) -- Xilio Therapeutics, Inc. (Nasdaq: XLO), a biotechnology company developing tumor-selective immuno-oncology therapies for people living with cancer, today announced pipeline and business highlights and reported financial results for the first quarter ended March 31, 2022.

“Leveraging our geographically precise solutions (GPS) platform, we are developing a pipeline of tumor-selective immunotherapies that have the potential to achieve meaningful anti-tumor activity while minimizing serious, systemic effects,” said René Russo, Pharm.D., president and chief executive officer of Xilio. “We continue to progress enrollment in our Phase 1 clinical programs, XTX101 and XTX202, with planned preliminary data readouts later this year, and we remain on track with our plans to submit an IND application for XTX301 in the second half of 2022. With our strong financial position and an outstanding team in place, we believe we are well-positioned to advance our pipeline of tumor-selective immuno-oncology programs with the goal of transforming the lives of people living with cancer.”

Pipeline and Business Progress

Cytokine Programs

• Enrollment is ongoing in the Phase 1 clinical trial evaluating XTX202 for the treatment of patients with solid tumors, with preliminary data anticipated to be reported in the second half of 2022. XTX202 is a tumor-selective interleukin-2 (IL-2) designed to localize activity in the tumor microenvironment, with the goal of overcoming the known tolerability challenges of existing IL-2 therapies while achieving enhanced anti-tumor activity as monotherapy and in combination with standard of care agents.
• Preclinical data from the XTX301 program was presented at the New York Academy of Sciences Frontiers in Cancer Immunotherapy 2022 conference on May 10, 2022. XTX301 demonstrated tumor-selective activation in patient-derived tumor explants, and a murine surrogate of XTX301 (mXTX301) induced significant tumor growth inhibition in a mouse model and improved tolerability compared to a non-tumor-selective version of mXTX301. View the poster online here.
• Xilio continues to anticipate submitting an investigational new drug application (IND) for XTX301, a tumor-selective interleukin-12 (IL-12), in the second half of 2022 for evaluation in patients with solid tumors.
  
  

Upcoming Presentations

• A trials-in-progress poster outlining details of the ongoing Phase 1/2 clinical trial for XTX202 will be presented at the American Society of Clinical Oncology (ASCO) 2022 Annual Meeting:
  
  Presentation title: A first-in-human, multicenter, phase 1/2, open-label study of XTX202, a masked and tumor-selective recombinant human interleukin-2 (IL-2) protein, in patients with advanced solid tumors
  Session date and time: Sunday, June 5, 2022, 8:00-11:00 AM CDT
  Abstract number: TPS2697

Checkpoint Inhibitor Program

• Enrollment is ongoing in the Phase 1 clinical trial evaluating XTX101, a tumor-selective anti-CTLA-4 monoclonal antibody, as a monotherapy and in combination with pembrolizumab, an anti-PD-1, for the treatment of patients with advanced solid tumors.
• Preliminary data for the Phase 1 clinical trial for XTX101 is anticipated to be reported from the monotherapy cohort in the middle of 2022 and from the combination cohort in the second half of 2022.

First Quarter 2022 Financial Results

• Cash Position: Cash and cash equivalents were $177.0 million as of March 31, 2022, as compared to $198.1 million as of December 31, 2021. The decrease was primarily driven by cash used in operations for the three months ended March 31, 2022.
• Research & Development (R&D) Expenses: R&D expenses were $14.9 million for the first quarter of 2022, compared to $11.6 million for the first quarter of 2021. The increase was primarily driven by increased costs associated with XTX301 and other preclinical programs, as well as higher personnel-related costs due to increased headcount.
• General & Administrative (G&A) Expenses: G&A expenses were $6.3 million for the first quarter of 2022, compared to $4.9 million for the first quarter of 2021. The increase was primarily driven by higher personnel-related costs due to increased headcount and other costs related to operating as a publicly traded company.
• Net Loss: Net loss was $21.4 million for the first quarter of 2022, compared to $16.7 million for the first quarter of 2021.

Financial Guidance

As a result of prioritization within the company’s preclinical portfolio, Xilio now anticipates that its existing cash and cash equivalents will be sufficient to fund its operating expenses and capital expenditure requirements into the first half of 2024.
