MINNEAPOLIS,
May 14, 2026 — Celcuity Inc. (Nasdaq: CELC), a clinical-stage biotechnology company focused on the development of targeted
therapies for the treatment of multiple solid tumor indications, today announced financial results for the first quarter ended March
31, 2026 and other recent business developments.
“With
positive results in both cohorts of the pivotal VIKTORIA-1 study, we believe gedatolisib regimens have the potential to advance the standard
of care in the second-line setting for a significant number of patients with HR+/HER2- advanced breast cancer, regardless of PIK3CA
status,” said Brian Sullivan, CEO and co-founder of Celcuity. “We are on track to launch gedatolisib commercially in anticipation
of its potential FDA approval in the third quarter of 2026, and we look forward to bringing this important therapy to physicians treating
patients with advanced breast cancer.”
Mr.
Sullivan added, “Our positive Phase 3 results, combined with our promising Phase 1b clinical trial results in treatment-naive
late-stage patients, provide a strong scientific rationale to evaluate gedatolisib combinations as first-line therapy. By expanding our
VIKTORIA-2 study to enable evaluation of treatment-naive patients who have endocrine-sensitive breast cancer, we are positioning
gedatolisib regimens to potentially be available for nearly all patients in the first-line setting, irrespective of their endocrine sensitivity
or PIK3CA status.”
First
Quarter 2026 Business Highlights and Other Recent Developments
| ● |
Celcuity
reported positive topline results from the PIK3CA mutant-type (“MT”) cohort of the Phase 3 VIKTORIA-1 clinical
trial evaluating gedatolisib in combination with fulvestrant with or without palbociclib in patients with hormone receptor positive
(“HR+”), human epidermal growth factor receptor 2 negative (“HER2-”) (“HR+/HER2-”), PIK3CA
MT locally advanced or metastatic breast cancer (“ABC”). |
| |
○ |
The
primary efficacy analysis of gedatolisib combined with fulvestrant and palbociclib (“gedatolisib triplet”) demonstrated
a statistically significant and clinically meaningful improvement in progression-free survival (“PFS”) compared with
alpelisib, a PI3Kα inhibitor, and fulvestrant. |
| |
|
|
| |
○ |
The
secondary endpoint comparing gedatolisib in combination with fulvestrant (“gedatolisib doublet”) versus alpelisib plus
fulvestrant, which was not part of the primary efficacy analysis in the hierarchical order, also demonstrated a statistically significant
and clinically meaningful improvement in PFS. |
| |
|
|
| |
○ |
Both
gedatolisib regimens were generally well tolerated, with manageable safety profiles, and no new safety signals. |
| |
|
|
| |
○ |
Detailed
data for the gedatolisib triplet and doublet regimens will be presented in a late-breaking abstract (“LBA”) oral session
on June 2, 2026, at the American Society of Clinical Oncology (“ASCO”) Annual Meeting in Chicago, Illinois. |
| |
|
|
| |
○ |
Celcuity
intends to submit these data to the FDA in the third quarter as a supplemental New Drug Application (“sNDA”) and to submit
VIKTORIA-1 data to other regulatory authorities outside the U.S. following the sNDA submission. |
| ● |
The
Phase 3 VIKTORIA-2 clinical trial now includes two studies, Study 1 and Study 2, each with independent statistical analysis plans
that include primary endpoints for their respective intent-to-treat populations. Study 1, which is ongoing, is evaluating the efficacy
and safety of gedatolisib in combination with palbociclib and fulvestrant in approximately 440 patients with endocrine-resistant
HR+/HER2- ABC. Study 2, which was added in conjunction with a VIKTORIA-2 protocol amendment, is evaluating the efficacy and safety
of gedatolisib in combination with palbociclib and letrozole in approximately 740 patients with treatment-naive endocrine-sensitive
HR+/HER2- ABC. Eligible patients include those whose cancer relapsed or progressed 12 months or more after completion of adjuvant
endocrine therapy, or those with de novo metastatic disease without prior endocrine therapy exposure. Approximately 60,000 adults
are newly diagnosed each year in the United States with endocrine-sensitive HR+/HER2- ABC.1 |
| |
|
| ● |
To
support its long-term lifecycle development plan, Celcuity submitted its first patent application to the United States Patent and
Trademark Office (“USPTO”) for a subcutaneous formulation of gedatolisib that would enable a patient to receive gedatolisib
as an injection as an alternative to an infusion. Development of the subcutaneous gedatolisib formulation is ongoing with the goal
of demonstrating clinical equivalence to the current intravenous formulation of gedatolisib. The subcutaneous formulation is aimed
to support potential future indications for gedatolisib regimens that may result in duration of treatment periods greater than several
years. |
| |
|
| ● |
In
January 2026, the FDA accepted the submission of Celcuity’s New Drug Application (“NDA”) for gedatolisib in HR+/HER2-
PIK3CA wild-type (“WT”) ABC. The FDA granted Priority Review and assigned a Prescription Drug User Fee Act (“PDUFA”)
goal date of July 17, 2026. |
First
Quarter 2026 Financial Results
Unless
otherwise stated, all comparisons are for the first quarter ended March 31, 2026, compared to the first quarter ended March 31, 2025.
Net
loss for the first quarter of 2026 was $52.8 million, or $0.97 per share, compared to a net loss of $37.0 million, or $0.86 per share,
for the first quarter of 2025. Non-GAAP adjusted net loss for the first quarter of 2026 was $46.8 million, or $0.86 per share, compared
to non-GAAP adjusted net loss of $34.7 million, or $0.81 per share, for the first quarter of 2025. Non-GAAP adjusted net loss excludes
stock-based compensation expense, non-cash interest expense, and non-cash interest income. Because these items have no impact on Celcuity’s
cash position, management believes non-GAAP adjusted net loss better enables Celcuity to focus on cash used in operations. For a reconciliation
of financial measures calculated in accordance with generally accepted accounting principles in the United States (“GAAP”)
to non-GAAP financial measures, please see the financial tables at the end of this press release.
Total
operating expenses were $50.5 million for the first quarter of 2026, compared to $36.1 million for the first quarter of 2025.
Research
and development (“R&D”) expenses were $33.1 million for the first quarter of 2026, compared to $29.8 million for the
prior year period. The $3.3 million increase in R&D expenses was primarily due to a $3.0 million increase in
employee-related and consulting expenses. The remaining increase was primarily due to a $5.4 million increase in manufacturing and other
costs, partially offset by a $5.1 million decrease in clinical trial costs, which was primarily driven by decreased costs for the VIKTORIA-1
Phase 3 clinical trial.
Selling,
general and administrative (“SG&A”) expenses were $17.4 million for the first quarter of 2026, compared to $6.3 million
for the prior year period. The $11.1 million increase in SG&A expenses was primarily due to an $8.7 million increase
in employee-related and consulting expenses, of which $6.6 million was due to commercial headcount additions and other
launch-related activities, and a $2.4 million increase primarily due to software costs, professional fees and other costs.
Net
cash used in operating activities for the first quarter of 2026 was $55.1 million, compared to $35.9 million for the prior year period.
Cash, cash equivalents and short-term investments were $387.1 million at the end of the first quarter of 2026. We expect cash, cash equivalents,
investments and drawdowns on our debt facility to finance our operations through 2027.

About
Celcuity
Celcuity
is a clinical-stage biotechnology company focused on the development of targeted therapies for the treatment of multiple solid tumor
indications. Our lead therapeutic candidate is gedatolisib, a kinase inhibitor of the PI3K/AKT/mTOR (“PAM”) pathway that
binds to all class I PI3K isoforms and the mTOR complexes, mTORC1 and mTORC2. By targeting all class I PI3K isoforms and mTORC1/2, gedatolisib
induces comprehensive inhibition of the PAM pathway. Its mechanism of action and pharmacokinetic properties are differentiated from other
currently approved and investigational therapies that target PI3Kα, AKT, or mTORC1 alone or together. Our Phase 3 clinical trial,
VIKTORIA-1, evaluating gedatolisib in combination with fulvestrant with or without palbociclib in patients with HR+/HER2- ABC, has reported
detailed results for Study 1, which evaluated patients with PIK3CA WT tumors, and announced topline results for Study 2, which
evaluated patients with PIK3CA MT tumors. Our Phase 3 clinical trial, VIKTORIA-2, is ongoing and incorporates two independent
studies, Study 1 and Study 2, evaluating two separate cohorts of patients with ABC who are treatment-naive in the advanced setting.
Study 1 is evaluating gedatolisib combined with palbociclib and fulvestrant as first-line treatment for patients with endocrine-resistant
HR+/HER2- ABC. Study 2 is evaluating gedatolisib combined with palbociclib and letrozole as first-line treatment for patients with endocrine-sensitive
HR+/HER2- ABC. A Phase 1b/2 clinical trial, CELC-G-201, evaluating gedatolisib in combination with darolutamide in patients with metastatic
castration resistant prostate cancer, is ongoing. More detailed information about Celcuity’s active clinical trials can be found
at ClinicalTrials.gov. Celcuity is headquartered in Minneapolis. Further information about Celcuity can be found at www.celcuity.com.

Cautionary
Statement Regarding Non-GAAP Financial Measures
This
press release contains references to non-GAAP adjusted net loss and non-GAAP adjusted net loss per share. Management believes these non-GAAP
financial measures are useful supplemental measures for planning, monitoring, and evaluating operational performance as they exclude
stock-based compensation expense, non-cash interest expense, and non-cash interest income from net loss and net loss per share. Management
excludes these items because they do not impact Celcuity’s cash position, which management believes better enables Celcuity to
focus on cash used in operations. However, non-GAAP adjusted net loss and non-GAAP adjusted net loss per share are not recognized measures
under GAAP and do not have a standardized meaning prescribed by GAAP. As a result, management’s method of calculating non-GAAP
adjusted net loss and non-GAAP adjusted net loss per share may differ materially from the method used by other companies. Therefore,
non-GAAP adjusted net loss and non-GAAP adjusted net loss per share may not be comparable to similarly titled measures presented by other
companies. Investors are cautioned that non-GAAP adjusted net loss and non-GAAP adjusted net loss per share should not be construed as
alternatives to net loss, net loss per share or other statements of operations data (which are determined in accordance with GAAP) as
an indicator of Celcuity’s performance or as a measure of liquidity and cash flows.
