• Strong balance sheet with $170.1 million cash runway to support multiple expected data readouts into mid-2024

NEW YORK, Aug. 11, 2022 (GLOBE NEWSWIRE) -- IO Biotech (Nasdaq: IOBT), a clinical-stage biopharmaceutical company developing novel, immune-modulating cancer therapies based on its T-win® technology platform, announced today financial results for the quarter ending June 30, 2022.

“We continue to advance our promising pipeline of novel cancer immunotherapies following clinical trial milestones achieved in the first half of the year,” said Mai-Britt Zocca, Ph.D., President and Chief Executive Officer of IO Biotech. “During the quarter we were pleased to announce the initiation and dosing of first patients our Phase 3 global combination trial of IOB102-103 with pembrolizumab as a potential first line treatment in advanced melanoma. We look forward to enrolling patients across the U.S., Australia and Europe. We will provide an update on the anticipated timing of the interim data once we have sufficient information. During the quarter, we also announced the initiation and dosing of the first patient in our Phase 2 basket trial of IO102-IO103 in combination with pembrolizumab. We expect to receive preliminary data in one indication in the second half of 2022, and additional data in 2023.

“In June, we shared two poster presentations highlighting clinical trials in progress with IO102-IO103 in combination with pembrolizumab in metastatic solid tumors and in untreated, unresectable or metastatic melanoma at the ASCO 2022 Annual Meeting. We are excited to build on the promising clinical activity seen from our previous Phase 1/2 clinical trial evaluating IO102-IO103 in metastatic melanoma as we believe that our T-win® platform―and its novel approach to activate naturally occurring T cells to target immunosuppressive mechanisms―has the potential to benefit patients in need of more treatment options. With a solid balance sheet and substantial cash runway to carry us through multiple expected data readouts into mid-2024, we look forward to sharing further progress in the coming months.”

Highlights for Second Quarter 2022 and Recent Weeks

• Announced initiation and dosing of the first patient in the Phase 3 IOB-013/KN-D18 trial of IO102-IO103 and KEYTRUDA® (pembrolizumab) as first-line treatment in advanced melanoma (NCT05155254);

Second Quarter Financial Results

• Net loss for the three months ended June 30, 2022 was $18.5 million, compared to $38.4 million for the quarter ended June 30, 2021.
• Research and development expenses were $12.2 million for the three months ended June 30, 2022, compared to $6.7 million for the three months ended June 30, 2021. The increase of $5.5 million was primarily related to an increase in preclinical studies and clinical trial-related activities for our IO102-IO103 product candidate, including the initiation of our Phase 3 clinical trial, of $2.6 million, an increase in costs for chemistry, manufacturing and control, activities of $0.5 million, and an increase in personnel costs of $2.1 million primarily related to an increase in headcount and related recruiting costs.
• General and administrative expenses were $5.9 million for the three months ended June 30, 2022, compared to $2.2 million for the three months ended June 30, 2021. The increase of $3.7 million was primarily related to an increase in personnel costs of $1.5 million primarily related to an increase in headcount and related recruiting costs and an increase in consultants and other costs of $2.7 million, partially offset by a decrease in professional services of $0.5 million related primarily to corporate legal fees and audit and tax fees.
• Other expense was a net expense of $0.2 million for the three months ended June 30, 2022 compared to a net expense of $29.4 million for the three months ended June 30, 2021. The increase of $29.2 million was mainly due to fair-value adjustments on preferred stock tranche obligations were losses of $29.4 million for the three months ended June 30, 2021.
• Cash and cash equivalents at June 30, 2022 were $170.1 million, compared to $211.5 million at December 31, 2021. Cash on hand is expected to support operations through anticipated data readouts into mid-2024.
