To date, 90 patients have been enrolled and treated with the Theralase Study Procedure, achieving the patient enrollment specified by the statistical analysis plan.

78 patients have completed the clinical study and were evaluated at all scheduled assessment visits or were prematurely removed by the principal investigator due to lack of response. There are 12 patients pending study completion.

Primary Endpoint Performance (CR at any Point in Time)
# % Confidence Interval (95%)
Complete Response ("CR") 56/87 64.4% [48.6, 80.2]
Total Response (CR and IR) 64/87 73.6% [56.7, 90.5]
Note: Indeterminate Response ("IR") is defined as negative cystoscopy (no evidence of Urothelial Cell Carcinoma ("UCC") in the bladder) and positive / suspicious urine cytology (detection of cancer in the urine, without a negative confirmatory bladder biopsy, suggesting UCC in the renal system other than the bladder).

Secondary Endpoint Performance (Duration of CR) (450 Days)
# % Confidence Interval (95%)
Complete Response 19/47 40.4% [23.8, 57.1]
Total Response 20/47 42.6% [26.6, 58.5]
Tertiary Endpoint Performance (Safety) (450 Days)
# %
Safety 78/78 100.0%
Note: Theralase believes all Serious Adverse Events ("SAEs") reported to date are unrelated or unlikely related to the Study Drug or Study Device.

These results exceed the International Bladder Cancer Group’s recommended guidelines of "clinically meaningful initial complete response rates for carcinoma in situ of at least 50% at 6 months and 30% at 12 months."1

Interim data from 47 patients indicates that complete response rates of 21.3% at both 2 and 3 years and 2.1% at 7 years were sustained.

Theralase will compile the clinical data in 2026 for presentation to Health Canada and FDA with an expected regulatory approval in 2027.

About Phase II Clinical Study:

Primary Endpoint: Efficacy (complete response at any point in time)

Secondary Endpoint: Efficacy (duration of complete response of 12 months)

Tertiary Endpoint: Safety (serious adverse events directly related to the study drug or study device that do not resolve within 450 days)

Study Procedure: Light-activated Ruvidar

Patient Population: Bacillus Calmette-Guérin ("BCG")-Unresponsive Non-Muscle Invasive Bladder Cancer ("NMIBC") Carcinoma In-Situ ("CIS"), who have failed standard-of-care therapy and are facing radical cystectomy (bladder removal) ("Study II").

About NMIBC:

NMIBC is a form of bladder cancer that is found in the inner layer cells of the bladder and does not invade into or beyond the muscle wall.2 In the United States, bladder cancer is the sixth most common cancer,3 fourth among men,4 and it is estimated that there will be approximately 84,870 new cases of bladder cancer in the U.S. in 2025.4 Historically, 75% of bladder cancer presents as NMIBC.5 In patients with high-risk NMIBC, intravesical BCG remains the first-line standard-of-care; however, approximately one third of patients with NMIBC will not respond to BCG therapy and 50% of those with an initial response will experience recurrence or progression of their disease.6 Current treatment options for BCG-unresponsive patients are very limited and National Comprehensive Cancer Network guidelines recommend cystectomy (partial or complete removal of the bladder).7

About Ruvidar:

Ruvidar is a small molecule activated by energy, intended for the safe and effective destruction of cancer, bacteria and viruses.

The summit, which gathered global academic and industry leaders from institutions including Dana-Farber, MD Anderson, Merck, and Roche, served as a critical forum for discussing the future of DDR therapeutics. Prof. Daugaard presented Rakovina’s AI-driven strategy to develop brain-penetrant inhibitors and participated in expert panels on translational strategy and investment alignment.

Validating the Strategy: Solving the "Brain Penetration" Gap

A focal point of the summit was the clinical landscape of ATR inhibitors, specifically considering recent Phase 3 data in non-small cell lung cancer (NSCLC)

Rakovina’s presentation highlighted a distinct competitive advantage: unlike current clinical-stage candidates, Rakovina’s lead kt-5000 series is designed to be dual-targeting (ATR + mTOR) and brain-penetrant.

"The consensus from the summit is that the field is hungry for a brain-penetrant ATR inhibitor," said Prof. Mads Daugaard, Chief Scientific Officer of Rakovina Therapeutics. "While other programs face challenges with patient stratification and blood-brain barrier penetration, our data supports a different path: positioning ATR inhibition in a PTEN-deficient context with added mTOR blockade to shut down resistance pathways. The feedback we received from clinical thought leaders was clear, we are addressing the exact limitations that have held this drug class back."

Interest in Novel ADC Payloads

In addition to its small-molecule pipeline, the Company received inbound interest regarding its kt-3000 series as potential payloads for Antibody-Drug Conjugates (ADCs). With major pharmaceutical companies actively seeking novel payloads to overcome resistance to current ADC therapies, Rakovina intends to prioritize proof-of-concept studies to further unlock this partnership value.

"Our participation in Boston transformed our standing from a quiet innovator to a recognized problem-solver in the DDR space," added Prof. Daugaard. "We have confirmed that our scientific rationale is sound, our targets are high-value, and our AI-designed molecules are doing what the competition cannot: reach the brain."

Net sales for Q4 2025 rose 4% to $540 million, with sales at constant exchange rates (CER) up 1% and exceeding the outlook for steady CER results compared to the year-ago period while overcoming macroeconomic challenges and the impact of the 2025 U.S. government shutdown. Solid ongoing trends among the growth pillars, which rose 7% CER, led the performance. Net sales results included headwinds of approximately $10 million from discontinued products (NeuMoDx and Dialunox) and the first-time contributions from the Parse acquisition that was completed in December 2025. Adjusted diluted EPS CER of $0.62 CER was above the outlook for about $0.60 CER.

For full-year 2025, QIAGEN achieved its increased sales outlook for 5% CER growth, which was at the high end of the outlook for about +4-5% CER growth. Net sales included headwinds of about $20 million from discontinued products (NeuMoDx and Dialunox) as well as contributions from the Parse acquisition. Adjusted diluted EPS was $2.38, with adjusted diluted EPS of $2.40 CER ahead of the outlook for about $2.38 CER and $0.12 ahead of the initial outlook for 2025. Diluted EPS was $1.94.

For 2026, QIAGEN expects net sales growth of at least 5% CER from 2025 driven by the growth pillars contributing about 9% CER growth and combined sales of about $1.64 billion CER. Adjusted diluted EPS is expected to be at least $2.50 CER compared with $2.38 in 2025.

"QIAGEN finished 2025 with disciplined execution, exceeding our outlook for sales and adjusted EPS in Q4 2025," said Thierry Bernard, CEO of QIAGEN. "Our performance underscores the strength of our portfolio and positions us well to demonstrate our commitment to delivering solid profitable growth in a challenging environment. Our growth pillars delivered 8% growth to reach $1.49 billion CER in combined sales in 2025 and keeping us on track toward our 2028 targets. We continue to drive efficiency and digitization across the organization to fund growth investments and expand profitability."

"We also made good progress in capital allocation," said Roland Sackers, CFO of QIAGEN. "We returned more than $1.1 billion to shareholders to date ahead of schedule and closed two bolt-on acquisitions with Genoox strengthening our QDI business and Parse expanding our Sample technologies portfolio with our entry into single-cell analysis. At the same time, we maintain significant flexibility to continue investing in growth and shareholder returns."

Investor presentation and conference call

A conference call is scheduled for Thursday, February 5, 2026, at 15:30 Frankfurt Time / 14:30 London Time / 9:30 New York Time. A live audio webcast will be available in the Investor Relations section of the QIAGEN website (www.qiagen.com), with a recording accessible after the event. The accompanying presentation will be published in advance under "Events and Presentations" in the same section.

Use of adjusted results

QIAGEN reports adjusted results and constant exchange rate (CER) measures, along with other non-GAAP financial metrics, to provide deeper insight into business performance. These include adjusted gross margin and profit, adjusted operating income and expenses, adjusted operating income margin, adjusted net income, adjusted income before taxes, adjusted diluted EPS, adjusted EBITDA, adjusted tax rate and free cash flow. Free cash flow is calculated as cash flow from operating activities less capital expenditures for property, plant and equipment. Adjusted results are non-GAAP measures that QIAGEN views as complementary to GAAP-reported results. They exclude items considered outside of ongoing core operations, subject to significant period-to-period fluctuation, or that reduce comparability with competitors and historical performance. QIAGEN also uses these non-GAAP and constant currency measures internally for planning, forecasting, reporting and employee compensation purposes. These metrics enable consistent comparison of current and past performance, which QIAGEN has historically presented on an adjusted basis.
