"The second quarter was marked by continued execution across the MICVO program and a financing that strengthened our balance sheet and extended our cash runway into the second quarter of 2027," said Tom Civik, Interim Chief Executive Officer and Director of Pyxis Oncology. "The additional capital gives us greater flexibility to incorporate longer patient follow-up and planned analyses into our next clinical updates. We expect to report updated monotherapy data in second-line and beyond recurrent/metastatic head and neck squamous cell carcinoma (2L+ R/M HNSCC) this fall, followed by updated first-line combination data with pembrolizumab in the fourth quarter. We remain focused on generating the clinical evidence needed to evaluate MICVO’s potential to address the significant unmet need in head and neck cancer, regardless of HPV status or prior therapy."

Pipeline & Corporate Updates

•
Pyxis Oncology expects to report updated data from the ongoing MICVO Phase 1 monotherapy study for 2L+ R/M HNSCC in Fall 2026. The update is expected to include patients treated at 5.4 mg/kg IV Q3W with a dose equivalent to or below a dose cap, together with detailed analyses of the dose cap impact on safety, tolerability, efficacy and initial durability.
•
The Company completed target enrollment in the Phase 1 Part 2 monotherapy dose expansion study in the first quarter of 2026.
•
The ongoing MICVO Phase 1 monotherapy study is a multi-part study. Part 1 was a dose escalation study across multiple doses and tumor types, with initial results shared in November 2024. Part 2, a dose expansion study in 2L+ R/M HNSCC, is currently ongoing. Preliminary Phase 1 study results in 2L+ R/M HNSCC were shared in December 2025, supporting MICVO’s broad potential to address a significant unmet need for patients regardless of HPV status or prior therapy.
•
The dose expansion study of the ongoing MICVO Phase 1 monotherapy study includes two arms: post-platinum and anti-PD-(L)1-experienced patients (Arm 1) and post-EGFRi and anti-PD-(L)1-experienced patients (Arm 2). Target enrollment for each arm of the study was n=~20.
•
In December 2025, a dose cap was implemented for higher body weight patients. Based on internal PK simulation modeling indicating that MICVO exposures with dose capping and adjusted ideal bodyweight (AIBW) dosing are expected to be comparable, dose capping was prioritized due to its operational simplicity and speed of implementation. The Fall 2026 monotherapy disclosure will remain focused on patients treated at or below the dose cap.
•
Pyxis Oncology expects to report updated data from the ongoing Phase 1/2 combination dose escalation study of MICVO and Merck’s (known as MSD outside of the US and Canada) anti-PD-1 therapy KEYTRUDA (pembrolizumab) for 1L R/M HNSCC patients in the fourth quarter of 2026.

•
The ongoing MICVO Phase 1/2 study evaluating MICVO in combination with KEYTRUDA (pembrolizumab) is currently in dose escalation across multiple doses for the treatment of 1L R/M HNSCC. Preliminary positive results for the treatment of 1L/2L+ R/M HNSCC were shared in December 2025.
•
In June 2026, Pyxis Oncology announced up to $114 million of private placement financing with new and existing healthcare-focused investors to advance MICVO through key clinical milestones.
•
On July 2, 2026, the Company completed the private placement which resulted in upfront gross proceeds of approximately $50 million, before deducting placement agent fees and offering expenses, and anticipates up to an additional approximately $64 million of gross proceeds, before placement agent fees, if the accompanying warrants are exercised in full for cash.
•
The upfront proceeds from the private placement, together with existing cash, extended the Company’s cash runway into the second quarter of 2027. The additional capital from the private placement provides flexibility to continue patient follow-up and allow the data to mature following completion of enrollment of the 2L+ R/M HNSCC study.

Second Quarter 2026 Financial Results

•
As of June 30, 2026, Pyxis Oncology had cash and cash equivalents, including restricted cash, and short-term investments, of $34.5 million. Additionally, on July 2, 2026, the Company completed the private placement which resulted in upfront gross proceeds of approximately $50 million (of which $10.0 million was received on June 30, 2026), before deducting placement agent fees and offering expenses. The Company believes that its cash and cash equivalents, including restricted cash, and short-term investments as of June 30, 2026, along with the upfront proceeds from the private placement, will be sufficient to fund its operations into the second quarter of 2027.
•
Research and development expenses were $16.1 million for the quarter ended June 30, 2026, compared to $17.1 million for the quarter ended June 30, 2025. The decrease was primarily due to a $3.5 million increase in clinical trial related expenses related to monotherapy and combination therapy of MICVO, $1.1 million increase in preclinical studies, offset by a reduction of $4.7 million in manufacturing costs.
•
General and administrative expenses were $9.9 million for the quarter ended June 30, 2026, compared to $5.4 million for the quarter ended June 30, 2025. The increase was primarily due to an increase in severance costs and higher stock-based compensation.
•
Net loss was $25.3 million, or ($0.40) per common share, for the quarter ended June 30, 2026, compared to $18.4 million, or ($0.30) per common share, for the quarter ended June 30, 2025.
