• General and administrative expenses also rose to $6.8 million from $4.0 million, reflecting increased headcount and public company costs.
• As of March 31, 2025, Upstream Bio had cash, cash equivalents, and short-term investments totaling $431.4 million.
• The company believes its current resources will fund operations through 2027.
• Top-line data from the CRSwNP Phase 2 clinical trial is expected in the third quarter of 2025, and top-line data from the severe asthma Phase 2 trial is anticipated in the first half of 2026.
• The first patient in the COPD program is expected to be dosed in mid-2025.

• Increased operating expenses, particularly in research and development, are driving the higher losses.
• Upstream Bio has no products approved for sale and has not generated any revenue from product sales since its inception.

Risks

• Clinical trial results may not replicate positive results from earlier studies.
• Regulatory approval processes are lengthy and uncertain.
• The company may face challenges in enrolling patients in clinical trials.

• The company may require additional funding to finance operations.

Future Outlook

Upstream Bio expects its current cash, cash equivalents, and short-term investments will be sufficient to fund operating expenses and capital expenditure requirements through 2027, with key clinical trial data readouts expected in the near term.

Industry Context

Upstream Bio is focused on developing treatments for inflammatory diseases, a competitive landscape with several major pharmaceutical and biotechnology companies already marketing or developing therapies for similar indications. The company's lead candidate, verekitug, targets the TSLP receptor, a clinically validated driver of inflammatory response, positioning it to potentially address unmet needs in severe respiratory disorders.

Comparison to Industry Standards

• Upstream Bio is competing with established players like Sanofi, Regeneron, AstraZeneca, and Amgen in the inflammatory disease market.
• These companies have significantly greater financial resources and expertise.
• Upstream Bio's approach with verekitug, targeting the TSLP receptor, is similar to tezepelumab (AstraZeneca/Amgen), but verekitug is an antagonist, potentially offering a differentiated product profile.
• Dupilumab (Sanofi/Regeneron) is another major biologic treatment for asthma, providing an existing benchmark for market acceptance and clinical efficacy.
• The success of Upstream Bio will depend on demonstrating superior efficacy, safety, or convenience compared to these existing and emerging therapies.

Related Party Transactions

• During the three months ended March 31, 2025, the Company received payments of $0.6 million in cost reimbursements from Maruho.

Stakeholder Impact

• Shareholders: The increased net loss may negatively impact shareholder value in the short term, but positive clinical trial results could improve sentiment.
• Employees: The company's growth plans may create opportunities for career advancement.
• Patients: Successful development of verekitug could provide a new treatment option for inflammatory diseases.
• Third-party payors: The cost-effectiveness of verekitug will be a key factor in coverage and reimbursement decisions.

Next Steps

• Report top-line data from CRSwNP Phase 2 clinical trial in Q3 2025.
• Report top-line data from severe asthma Phase 2 trial in H1 2026.
• Dose the first patient in the COPD program in mid-2025.
• Continue to advance verekitug through clinical development.
• Seek regulatory approvals for verekitug in current or new indications.
