"The second quarter of 2024 was a time of continued progress at Mersana as we advanced dose escalation in Phase 1 clinical trials of XMT-1660, our lead Dolasynthen ADC candidate, and XMT-2056, our lead Immunosynthen ADC candidate," said Martin Huber, M.D., President and Chief Executive Officer of Mersana Therapeutics. "At the same time, we made further progress in our collaborations while also benefiting from last year’s efforts to reduce operating expenses. We believe these collective accomplishments have put us in a strong position as we approach our initial clinical data readout for XMT-1660, which is planned for the second half of this year."

Recent Accomplishments, Strategic Priorities and Expected Milestones

XMT-1660: Mersana continues to advance its Phase 1 clinical trial of XMT-1660, the company’s lead Dolasynthen ADC candidate targeting B7-H4. The dose escalation portion of the trial is ongoing at a dose level of 80 milligrams per meter squared every four weeks, and a maximum tolerated dose has yet to be established. Additionally, the company has been proactively exploring more frequent dosing and enrolling patients in backfill cohorts to inform the optimal dose and schedule for expansion. Mersana plans to share initial safety, tolerability, efficacy and biomarker data from dose escalation and backfill cohorts and plans to initiate the expansion portion of the trial in the second half of 2024.

XMT-2056: Mersana continues to enroll patients in the dose escalation portion of its Phase 1 clinical trial of XMT-2056, the company’s lead Immunosynthen ADC candidate targeting a novel HER2 epitope. GSK plc has an exclusive global license option to co-develop and commercialize XMT-2056. Additionally, mechanistic underpinnings related to Mersana’s Immunosynthen platform were recently described in a Nature Communications publication entitled, "Tumor Cell-Directed STING Agonist Antibody Drug Conjugates Induce Type III Interferons and Anti-Tumor Innate Immune Responses."

Collaborations: Mersana continues to advance its Johnson & Johnson and Merck KGaA, Darmstadt, Germany collaborations. The collaboration with Merck KGaA, Darmstadt, Germany focuses on the discovery of novel Immunosynthen ADCs for up to two targets. The collaboration with Johnson & Johnson focuses on the discovery of novel Dolasynthen ADCs for up to three targets. In August 2024, Mersana earned an $8 million development milestone under the Johnson & Johnson collaboration, for which payment is due in the third quarter of 2024.

Second Quarter 2024 Financial Results

Cash, cash equivalents and marketable securities as of June 30, 2024 were $162.7 million. Mersana continues to expect that its capital resources will be sufficient to support its current operating plan commitments into 2026.
Net cash used in operating activities for the second quarter of 2024 was $21.8 million.
Collaboration revenue for the second quarter of 2024 was $2.3 million, compared to $10.7 million for the same period in 2023. The year-over-year change was primarily related to reduced collaboration revenue recognized under Mersana’s collaboration and license agreements with Johnson & Johnson and Merck KGaA, Darmstadt, Germany.
Research and development (R&D) expenses for the second quarter of 2024 were $17.2 million, compared to $49.0 million for the same period in 2023. Included in R&D expenses for the second quarter of 2024 were $2.4 million in non-cash stock-based compensation expenses. The year-over-year decline in R&D expenses was primarily related to reduced costs associated with manufacturing and clinical activities for UpRi, a discontinued ADC candidate, and reduced employee compensation expense following the company’s restructuring in 2023.
General and administrative (G&A) expenses for the second quarter of 2024 were $10.5 million, compared to $18.2 million during the same period in 2023. Included in G&A expenses for the second quarter of 2024 were $2.0 million in non-cash stock-based compensation expenses. The year-over-year decline in G&A expenses was primarily related to reduced consulting and professional services fees and reduced employee compensation expense following the aforementioned restructuring.
Net loss for the second quarter of 2024 was $24.3 million, or $0.20 per share, compared to a net loss of $54.3 million, or $0.47 per share, for the same period in 2023.

"We continued to make significant progress this quarter highlighted by additional positive data from the Phase 2 portion of the ongoing Phase 2/3 Orbit study in patients with OI," said Dr. Denise Scots-Knight, Chief Executive Officer of Mereo. "These data showed that the statistically significant annualized fracture rate reduction of 67% was maintained following treatment with setrusumab for at least 14 months of follow-up, further demonstrating the potential of setrusumab to generate long-term, clinically meaningful benefit for people living with OI. On alvelestat, we continue to work through the detailed regulatory submissions to ensure the AATD program is Phase 3-ready by the end of the year, in parallel with our ongoing discussions with multiple potential partners. With the proceeds from our June financing, we are well positioned through our key value inflection milestones and to support the ongoing pre-commercial activities essential for a successful launch of setrusumab in Europe following its potential approval."

Second Quarter 2024 Highlights, Recent Developments and Anticipated Milestones

Setrusumab (UX143)

•
The Phase 3 Orbit and Cosmic studies of setrusumab in OI, conducted by our partner Ultragenyx, were fully enrolled as of April 30, 2024.

•
On June 11, 2024, Mereo and Ultragenyx, announced positive 14-month results from the Phase 2 portion of the ongoing Phase 2/3 Orbit study (NCT05125809).

•
The results from the Phase 2 portion of the Orbit study demonstrated that, as of the May 24, 2024 data cut-off date, treatment with setrusumab continued to significantly reduce incidence of fractures in patients with OI. Treatment with setrusumab also resulted in ongoing and meaningful improvements in lumbar spine bone mineral density (BMD) at month 12 without evidence of plateau.

•
The median annualized rate of radiologically confirmed fractures across all 24 patients in the 2 years prior to treatment was 0.72. Following a mean treatment duration period of 16 months, the median annualized fracture rate was reduced by 67% to 0.00 (p=0.0014; n=24).

•
The reduction in annualized fracture rates was associated with continued, clinically meaningful increases in BMD. At the 12-month time point, treatment with setrusumab resulted in a mean increase in lumbar spine BMD from baseline of 22% (p<0.0001, n=19) and an improvement of the lumbar spine BMD Z-score from a mean baseline of -1.73 to -0.49 at 12 months. The improvements in BMD and Z-scores were significant and consistent across all OI sub-types studied.

•
As of the data cut-off date, there were no treatment-related serious adverse events observed in the study and no reported hypersensitivity reactions related to setrusumab.

•
Research has been published from our osteogenesis imperfecta program: The 12-month results for the Phase 2b ASTEROID study in the Journal of Bone and Mineral Research and the first publication from SATURN (Systematic Accumulation of Treatment practices and Utilization, Real world evidence, and Natural history data for OI), which is expected to provide a coordinated data set across multiple treatment centers for OI across European countries, to support pricing and reimbursement decisions.

•
More detailed data from the Phase 2 portion of the ongoing Phase 2/3 Orbit study will be presented at an upcoming scientific meeting

Alvelestat (MPH-966)

•
The Company continues to engage with multiple potential partners for the development and commercialization for alvelestat in AATD

•
At the end of Q2, Mereo submitted the initial validation work for SGRQ in AATD and the detailed Phase 3 package including the study protocol to the FDA in order to maintain the potential to start the Phase 3 study around the end of 2024.

Second Quarter 2024 Financial Results

Total research and development (R&D) expenses increased by $1.2 million, or 33%, from $3.7 million in the second quarter of 2023 to $4.9 million in the second quarter of 2024. The increase was primarily due to increases of $1.9 million and $0.9 million of R&D expenses for alvelestat and setrusumab, respectively, partially offset by a $1.5 million reduction in R&D expenses for etigilimab. The increase in the program expenses for alvelestat primarily relates to preparatory work for the Phase 3 study, including manufacturing and drug formulation activities, SGRQ validation activities and regulatory filings and interactions. The increase in program expenses for setrusumab is driven by additional activities in Europe and resources for the input into development, regulatory and manufacturing plans with our partner, Ultragenyx, as the global development program is funded by Ultragenyx pursuant to our license and collaboration agreement. The reduction in etigilimab expenses was primarily due to the winding down and completion during 2023 of the open label Phase 1b/2 basket study in combination with an anti-PD-1 in a range of tumor types.

General and administrative (G&A) expenses increased by $5.2 million from $2.7 million in the second quarter of 2023 to $7.9 million in the second quarter of 2024. The increase is primarily related to: (i) a $3.4 million reduction in expenses recognized in the second quarter of 2023 for amounts from our depository to reimburse certain expenses incurred by us in respect of our ADR program, whereas in 2024, $1.7 million was received from our depository in the first quarter of 2024; and (ii) pre-commercial activities to lay the foundation for the commercial launch of setrusumab in Europe, including those to support pricing and reimbursement by HTA authorities and payor decision-makers in Europe of $0.9 million.

Net loss for the second quarter of 2024 was $12.3 million, compared to $1.8 million during the second quarter of 2023, driven primarily by a one-time milestone payment of $9.0 million received in the second quarter of 2023, and increases in R&D expenses and G&A expenses in the second quarter of 2024.

As of June 30, 2024, the Company had cash and cash equivalents of $87.4 million, compared to $57.4 million as of December 31, 2023. This includes net proceeds of the $50 million underwritten registered direct offering priced at-the-market on June 14, 2024. The Company expects, based on current operational plans, that its existing cash and cash equivalents balance will enable it to fund its currently committed clinical trials, operating expenses including pre-commercial activities for setrusumab, and capital expenditure requirements into 2027. This guidance does not include any potential upfront payments associated with a partnership for alvelestat or business development activity around any of the Company’s non-core programs.

Total ordinary shares issued as of June 30, 2024, were 768,821,274. Total ADS equivalents as of June 30, 2024, were 153,764,254, with each ADS representing five ordinary shares of the Company.

On August 13, 2024 Kezar Life Sciences, Inc. (Nasdaq: KZR), a clinical-stage biotechnology company developing novel small molecule therapeutics to treat unmet needs in immune-mediated diseases and cancer, reported financial results for the second quarter ended June 30, 2024, and provided a business update (Press release, Kezar Life Sciences, AUG 13, 2024, View Source [SID1234645812]).

"We are thrilled to announce completion of enrollment to our PORTOLA trial and look forward to sharing topline results earlier than expected in the first half of 2025. This important milestone brings us one step closer to delivering zetomipzomib as a new treatment option for patients suffering from autoimmune hepatitis, a disease of significant unmet medical need," said Chris Kirk, PhD, Kezar’s Co-founder and Chief Executive Officer. "In addition, we are continuing to see strong enrollment activity in our global PALIZADE trial and look to continue this momentum by focusing our clinical resources on zetomipzomib development programs going forward. I want to thank our team for their hard work and commitment across all of our clinical trials and share our gratitude to the patients, their families and the study investigators, for their participation in these studies."

Zetomipzomib: Selective Immunoproteasome Inhibitor

PALIZADE – Phase 2b clinical trial of zetomipzomib in patients with active lupus nephritis (LN) (ClinicalTrials.gov: NCT05781750)

•
PALIZADE is a global, placebo-controlled, randomized, double-blind Phase 2b clinical trial evaluating the efficacy and safety of two dose-levels of zetomipzomib in patients with active LN. Target enrollment will be 279 patients, randomly assigned (1:1:1) to receive 30 mg of zetomipzomib, 60 mg of zetomipzomib or placebo subcutaneously once weekly for 52 weeks, in addition to standard background therapy. Background therapy can, but will not be mandated to, include standard induction therapy. Over the initial 16 weeks, there will be a mandatory corticosteroid taper to 5 mg per day or less. End-of-treatment assessments will occur at Week 53. The primary efficacy endpoint is the proportion of patients who achieve a complete renal response (CRR) at Week 37, including a urine protein-to-creatine ratio (UPCR) of 0.5 or less without receiving rescue or prohibited medications.
•
Our partner, Everest Medicines, announced that the first patient in China was dosed with zetomipzomib as part of our global PALIZADE trial. Kezar entered into a collaboration and license agreement with Everest Medicines in September 2023 to develop and commercialize zetomipzomib in Greater China, South Korea and Southeast Asia.

•
Kezar expects to report topline data from PALIZADE in mid-2026.

PORTOLA – Phase 2a clinical trial of zetomipzomib in patients with autoimmune hepatitis (AIH) (ClinicalTrials.gov: NCT05569759)

•
PORTOLA is a placebo-controlled, randomized, double-blind Phase 2a clinical trial evaluating the efficacy and safety of zetomipzomib in patients with AIH that are insufficiently responding to standard of care or have relapsed. The study has completed enrollment of 24 patients, randomized (2:1) to receive 60 mg of zetomipzomib or placebo in addition to background therapy for 24 weeks, with a protocol-suggested steroid taper. The primary efficacy endpoint will measure the proportion of patients who achieve a complete biochemical response by Week 24 measured as normalization of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and Immunoglobulin G (IgG) values (if elevated at baseline), with steroid dose levels not higher than baseline.
•
Kezar expects to report topline data from PORTOLA in the first half of 2025.

KZR-261: Broad-Spectrum Sec61 Translocon Inhibitor

KZR-261-101– Phase 1 clinical trial of KZR-261 in patients with locally advanced or metastatic solid malignancies (ClinicalTrials.gov: NCT05047536)

•
The Phase 1 clinical trial of KZR-261 is being conducted in two parts: dose escalation and dose expansion in tumor-specific solid tumors. The study is designed to evaluate safety and tolerability, pharmacokinetics and pharmacodynamics, identify a recommended Phase 2 dose and explore the preliminary anti-tumor activity of KZR-261 in patients with locally advanced or metastatic disease.
•
Enrollment has been stopped in the KZR-261 Phase 1 study, and clinical resources are being reallocated toward development of zetomipzomib in AIH and LN. Patients already enrolled in the study will continue to have access to KZR-261.
•
A total of 61 patients enrolled across the dose-escalation and dose expansion portions of the study, which included seven patients enrolled in the melanoma cohort of the dose-expansion portion at a dose level of 60 mg/m2.
•
No objective responses have been observed to date in the study. Five patients (two with melanoma) within the dose escalation portion of the study experienced stable disease for four months or longer, of which two patients (melanoma; head and neck) experienced stable disease for twelve months or longer.
•
KZR-261 has demonstrated consistent pharmacokinetics across all dose levels to date, and evidence of dose-dependent inhibition of Sec61 has been observed in patient blood samples.
•
Kezar plans to report full data at a medical conference following completion of the study.

Financial Results

•
Cash, cash equivalents and marketable securities totaled $164.2 million as of June 30, 2024, compared to $201.4 million as of December 31, 2023. The decrease was primarily attributable to cash used in operations to advance clinical-stage programs.

•
Research and development (R&D) expenses for the second quarter of 2024 decreased by $4.7 million to $16.3 million, compared to $21.0 million in the second quarter of 2023. This decrease was primarily due to the Company’s strategic restructuring in October 2023 to prioritize its clinical-stage programs, reducing personnel-related costs and spending in its early-stage research activities. The decrease was partially offset by the increased clinical trial costs related to the PALIZADE and PORTOLA trials.
•
General and administrative (G&A) expenses for the second quarter of 2024 decreased by $0.2 million to $5.6 million compared to $5.8 million in the second quarter of 2023. The decrease was primarily due to a decrease in legal and professional service expenses.
•
Restructuring and impairment charges for the second quarter of 2024 were $1.5 million. The charges were primarily related to an impairment loss of the right-of-use asset related to vacated space in the company’s leased office facilities.
•
Net loss for the second quarter of 2024 was $21.5 million, or $0.30 per basic and diluted common share, compared to a net loss of $24.3 million, or $0.34 per basic and diluted common share, for the second quarter of 2023.
•
Total shares of common stock outstandingwere 72.9 million shares as of June 30, 2024. Additionally, there were options to purchase 15.3 million shares of common stock at a weighted-average exercise price of $2.18 per share and 0.2 million restricted stock units outstanding as of June 30, 2024.
