BOSTON, Nov. 12, 2024 (GLOBE NEWSWIRE) -- Compass Therapeutics, Inc. (NASDAQ:CMPX), a clinical-stage, oncology-focused biopharmaceutical company developing proprietary antibody-based therapeutics to treat multiple human diseases, today reported third quarter 2024 financial results and provided a business update.
"We continue to be extremely encouraged with the progress across our clinical-stage programs, with three drugs already in the clinic and our deepening understanding of the potential clinical and regulatory pathways for each," said Thomas Schuetz, MD, PhD, CEO of Compass and Vice Chairman of the Board of Directors. "In particular, we recently presented data showing a correlation between NCAM (CD56) expression and disease control with CTX-471 monotherapy. Given the high prevalence of NCAM expression across multiple tumor types, we are planning a Phase 2 monotherapy trial evaluating CTX-471 in patients whose tumors express this biomarker. With respect to our lead asset, CTX-009, we are on track for a top-line data readout in the U.S. at the end of the first quarter of 2025 for COMPANION-002, our Phase 2/3 combination study in patients with advanced BTC. Regarding CTX-009 in CRC, we are designing a Phase 2 study in the second-line setting in patients with metastatic CRC utilizing the DLL4 biomarker based on our observations from COMPANION-003."
DEVELOPMENT PIPELINE UPDATES:
CTX-009 (DLL4 and VEGF-A bispecific antibody)
- Top-line data readout in the U.S. on track for the end of Q1 2025 for COMPANION-002, the Company's Phase 2/3 randomized trial of CTX-009 in combination with paclitaxel in patients with advanced BTC (see press release).
- Stage 1 of COMPANION-003, a Phase 2 trial in the U.S. of CTX-009 as a monotherapy in patients with advanced metastatic CRC was completed and, although it is not advancing to Stage 2, showed encouraging preliminary efficacy and safety results. The data from this study has informed the design of a Phase 2 study in the second-line setting in combination with chemotherapy in patients with DLL4-positive CRC.
- An investigator sponsored study of CTX-009 in patients with BTC in the first-line setting at The University of Texas MD Anderson Cancer Center is being initiated. CTX-009 will be added to the standard first-line regimen of gemcitabine, cisplatin, and durvalumab.
CTX-471 (CD137 agonist antibody)
- CTX-471, a novel anti-CD137 agonist antibody, demonstrated durable clinical responses in Phase 1, which were presented at the American Society of Clinical Oncology (ASCO) Annual Meeting earlier this year.
- An analysis of biopsy specimens from patients treated with CTX-471 monotherapy in the Phase 1b study identified pharmacodynamic and response biomarkers. These data were presented at the 39th Society for Immunotherapy of Cancer 2024 Annual Meeting. Specifically, data showed a correlation between the levels of NCAM (CD56) expression and disease control in patients treated with CTX-471 monotherapy.
CTX-8371 (PD-1 x PD-L1 bispecific antibody)
- CTX-8371 is a next generation bispecific checkpoint inhibitor that simultaneously targets PD-1 and PD-L1 and exhibits a unique mechanism-of-action that involves cleavage of cell surface PD-1.
- The second dosing cohort in the Phase 1 dose-escalation study of CTX-8371 is fully enrolled; no dose limiting toxicities (DLTs) have been observed to date. Enrollment into the third dosing cohort is expected to begin in the coming month.
Pre-clinical Research
- Continuing exploration of the synergies observed in pre-clinical and discovery work between VEGF blockade, CD137 agonism, checkpoint inhibition, and other cell engagement to identify novel bispecific antibody drug candidates with complementary anti-tumor activity.
FINANCIAL RESULTS:
Net loss for the quarter ended September 30, 2024, was $10.5 million or $0.08 per share of common stock, compared to $10.0 million or $0.08 per share of common stock for the same period in 2023. Net loss for the nine months ended September 30, 2024, was $34.3 million or $0.25 per share of common stock, compared to $29.1 million or $0.23 per share of common stock for the same period in 2023.
Research and Development (R&D) Expenses
R&D expenses were $8.6 million for the quarter ended September 30, 2024, as compared to $8.8 million for the same period in 2023, a decrease of $0.2 million. R&D expenses were $29.3 million for the nine months ended September 30, 2024, as compared to $25.7 million for the same period in 2023, an increase of $3.6 million. This increase was primarily attributable to a $5.2 million increase in clinical costs related to the COMPANION-002 trial, partially offset by $3.2 million less in manufacturing expense for CTX-009.
General and Administrative (G&A) Expenses
G&A expenses were $3.6 million for the quarter ended September 30, 2024, as compared to $3.1 million for the same period in 2023, an increase of $0.5 million. The increase was due to $0.5 million more stock compensation expense than prior year. G&A expenses were $11.6 million for the nine months ended September 30, 2024, as compared to $9.3 million for the same period in 2023, an increase of $2.3 million. The increase was due to expenses related to the departure of the CEO in the second quarter and more stock compensation expense than prior year.
CASH POSITION:
As of September 30, 2024, cash and marketable securities were $135 million as compared to $152 million as of December 31, 2023, which gives a cash runway into the first quarter of 2027.
During the first nine months of 2024, Compass decreased its cash position by $17 million, primarily by cash used in operating activities partially offset by $18 million cash received from issuance of stock through its at-the-market offering program.
About CTX-009
CTX-009 is a bispecific antibody that simultaneously blocks Delta-like ligand 4 (DLL4) and vascular endothelial growth factor A (VEGF-A) signaling pathways, which are critical to angiogenesis and tumor vascularization. Preclinical and early clinical data of CTX-009 suggest that blockade of both pathways provides robust anti-tumor activity across several solid tumors, including colorectal, gastric, cholangiocarcinoma, pancreatic and non-small cell lung cancer. Partial responses to CTX-009 as a monotherapy have been observed in heavily pre-treated patients with cancer who were resistant to approved anti-VEGF therapies. COMPANION-002, a Phase 2/3 trial of CTX-009 (DLL4 and VEGF-A bispecific antibody) plus paclitaxel versus paclitaxel monotherapy in patients with previously treated, unresectable advanced metastatic or recurrent biliary tract cancers (BTC) is ongoing. Clinical Trial information: NCT05506943.
About CTX-471
CTX-471 is a fully human monoclonal antibody that binds and activates a novel epitope of the co-stimulatory receptor CD137, also known as 4-1BB, a member of the tumor necrosis factor receptor superfamily. The antibody is currently being evaluated in a Phase 1b clinical trial in patients with solid tumors that have progressed after at least three months on an approved PD-1 or PD-L1 inhibitor. Initial results reported from a monotherapy cohort of the study included five clinical responses, all in patients who previously received checkpoint inhibitors, including a durable partial response (PR) in a patient with small-cell lung cancer that converted to a complete response (as confirmed by PET scan) and four additional PRs (one unconfirmed) in patients with melanoma and mesothelioma. CTX-471 has been generally well tolerated. In preclinical studies, CTX-471 has demonstrated potent monotherapy activity against multiple syngeneic tumor models, including the generation of long-term functional immunological memory. Clinical Trial information: NCT03881488.
About CTX-8371
CTX-8371 is a next generation bispecific checkpoint inhibitor that simultaneously targets PD-1 and PD-L1 and exhibits a unique mechanism-of-action that involves cleavage of cell surface PD-1. CTX-8371 received FDA clearance of the IND in October 2023. The Phase 1 CTX-8371 study design includes five ascending doses (0.1, 0.3, 1.0, 3.0, and 10 mg/kg) and the study is enrolling patients with melanoma, non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), Hodgkin Lymphoma, and triple negative breast cancer (TNBC) who have progressed on at least one prior regimen containing checkpoint blocker. No DLTs observed in the first dosing cohort and the second dosing cohort has been initiated. Clinical Trial information: NCT06150664.
