Upstream Bio Reports Third Quarter 2024 Financial Results and Recent Business Highlights

 

– Advancing Phase 2 clinical trials of verekitug in patients with severe asthma and CRSwNP –

 

– Commenced startup for a Phase 2 clinical trial in COPD; on track for first patient to be dosed in H2 2025 –

 

– Completed upsized IPO with gross proceeds of approximately $293 million, extending runway through 2027 –

 

WALTHAM, Mass. – November 7, 2024 - Upstream Bio, Inc. (Nasdaq: UPB), a clinical-stage company developing treatments for inflammatory diseases, with an initial focus on severe respiratory disorders, today reported financial results for the third quarter ended September 30, 2024, and provided a summary of recent business highlights.

“At Upstream Bio, we continue to make significant progress toward developing verekitug, the only monoclonal antibody currently in clinical development that targets and inhibits the thymic stromal lymphopoietin (TSLP) receptor, in severe respiratory diseases with substantial unmet needs. We expect to report top-line data from our ongoing Phase 2 clinical trials in severe asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) in the second half of 2026 and the second half of 2025, respectively. In addition, we have initiated planning activities for a Phase 2 clinical trial in chronic obstructive pulmonary disease (COPD), and we anticipate dosing our first patient in this program in the second half of 2025,” said Rand Sutherland, M.D., Upstream Bio’s Chief Executive Officer. “Our recently completed initial public offering has provided us with sufficient capital to fund our planned operations through 2027, which will support our strategy of leveraging verekitug’s unique mechanism of action to improve treatment options for patients living with severe inflammatory diseases.”

 

Dr. Sutherland continued, “This quarter, we also presented data from our Phase 1b multiple ascending dose trial of verekitug in asthma patients. PK/PD modeling of data from this study demonstrated that verekitug is highly potent, with an approximately 50% greater effect on fractional exhaled nitric oxide (FeNO) than has been previously reported with tezepelumab. Our ongoing Phase 2 clinical trials are testing two extended dosing intervals of 12 and 24 weeks for patients with severe asthma, and 12 weeks for patients with CRSwNP, to determine whether verekitug’s potency will translate to a differentiated clinical profile, both from the standpoint of efficacy and dosing frequency.”

Third Quarter 2024 Financial Results

 

As of September 30, 2024, Upstream had cash, cash equivalents and short-term investments of $220.7 million, as compared to $109.8 million as of December 31, 2023. Upstream’s cash, cash equivalents and short-term investments as of September 30, 2024, together with net proceeds from the closing of its IPO in October 2024 of approximately $268.7 million, is expected to fund planned operations through 2027.

 

Research and development expenses were $15.4 million for the quarter ended September 30, 2024, compared to $7.8 million for the same period in 2023. The increase of $7.6 million was primarily driven by an increase in clinical and manufacturing expenses related to our verekitug program.

 

General and administrative expenses were $4.1 million for the quarter ended September 30, 2024, compared to $2.2 million for the same period in 2023. The increase of $1.8 million was primarily driven by an increase in personnel expenses.

 

Net loss was $16.0 million for the quarter ended September 30, 2024, compared to a net loss of $3.1 million for the same period in 2023. The increase of $12.9 million was largely due to increased research and development and general and administrative expenses, and other income recorded due to a change in the value of preferred stock right tranche liabilities.

The Company has advanced this highly potent monoclonal antibody into separate Phase 2 trials for the treatment of severe asthma and chronic rhinosinusitis with nasal polyps and plans to initiate development in chronic obstructive pulmonary disease. Upstream Bio’s team is committed to maximizing verekitug’s unique attributes to address the substantial unmet needs for patients underserved by today’s standard of care.
