About Nitric Oxide
Nitric Oxide (NO) is a potent molecule, naturally synthesized in the human body, proven to play a critical role in a broad array of biological functions. In the airways, NO targets the vascular smooth muscle cells that surround the small resistance arteries in the lungs. Currently, exogenous inhaled NO is used in adult respiratory distress syndrome, post certain cardiac surgeries and persistent pulmonary hypertension of the newborn to treat hypoxemia. Additionally, NO is believed to play a key role in the innate immune system and in vitro studies suggest that NO possesses anti-microbial activity not only against common bacteria, including both gram-positive and gram-negative, but also against other diverse pathogens.

On March 14, 2023 Bellicum Pharmaceuticals, Inc. (Nasdaq: BLCM), reported its decision to discontinue its ongoing Phase 1/2 clinical trials evaluating the safety and preliminary efficacy of its GoCAR-T cell product candidates in combination with rimiducid in heavily pre-treated cancer patients (Press release, Bellicum Pharmaceuticals, MAR 14, 2023, View Source [SID1234628698]). The trials for BPX-601 and BPX-603 are being discontinued following the Company’s assessment of the risk/benefit profile of BPX-601 in combination with rimiducid.

The most recent patient treated in the Phase 1/2 trial of BPX-601 in metastatic castration-resistant prostate cancer (mCRPC) experienced serious immune-mediated adverse events including Grade 4 cytokine release syndrome (CRS), the second dose-limiting toxicity observed in this cohort of dose escalation. The company paused enrollment in its clinical studies and conducted a thorough review of the risk/benefit observed to date. While clinically meaningful efficacy has been observed—including 5 of 9 mCRPC patients treated achieving PSA50 response, 4 of whom achieved PSA90 response—the Company believes it does not have the necessary resources to optimize either the clinical dose and schedule of BPX-601 cells and the activating agent rimiducid, or the design of the BPX-601 cell construct to achieve a favorable risk/benefit profile.

The Company is communicating with clinical trial sites and regulatory agencies regarding its decision to discontinue its trials, and an evaluation of the Company’s strategic alternatives is underway.

The abstract and presentation describe the mechanism of action of MCLA-129, an antibody-dependent cellular cytotoxicity (ADCC) enhanced Biclonics that targets epidermal growth factor receptor (EGFR) and c-MET in non-small cell lung cancer (NSCLC) and other solid tumors in comparison to the EGFR x c-MET bispecific antibody amivantamab. MCLA-129 is a Biclonics common light chain bispecific antibody with multiple mechanisms of action, including inhibition of EGFR and c-MET ligand binding, which is observed in preclinical assays to have antibody-dependent cellular phagocytosis and ADCC comparable or more potent than amivantamab.

Presentation Details:

MCLA-129

Title: Preclinical evaluation of MCLA-129, a bispecific antibody targeting EGFR and c-MET on solid tumor cells, in comparison with amivantamab
Session Category: Experimental and Molecular Therapeutics
Session: Targeting Protein Kinases and Phosphatases for Therapy 1
Date: Tuesday, April 18, 2023
Time: 1:30-5:30 p.m. ET
Poster #: 12
Abstract #: 4999

The full abstract is available on the AACR (Free AACR Whitepaper) website. The poster will be available on the Merus website at the start of the session.

MCLA-129 is in clinical development in a phase 1/2, open-label clinical trial evaluating MCLA-129 monotherapy in EGFRex20 NSCLC, MetEx14 NSCLC, and in head and neck squamous cell carcinoma, as well as in combination with Tagrisso (osimertinib) in treatment naïve EGFR mutant (m) NSCLC and in EGFRm NSCLC that has progressed on Tagrisso.

MCLA-129 is subject to a collaboration and license agreement with Betta Pharmaceuticals Co. Ltd. (Betta), which permits Betta to exclusively develop MCLA-129 and potentially commercialize exclusively in China, while Merus retains global rights outside of China.

About MCLA-129
MCLA-129 is an antibody-dependent cellular cytotoxicity-enhanced Biclonics that is designed to inhibit the EGFR and c-MET signaling pathways in solid tumors. Preclinical data have shown that MCLA-129 can effectively treat TKI-resistant non-small cell lung cancer (NSCLC) in xenograft models of cancer. MCLA-129 is designed to have two complementary mechanisms of action: blocking growth and survival pathways to stop tumor expansion and recruitment and enhancement of immune effector cells to eliminate the tumor.

On March 14, 2023 Merus N.V. (Nasdaq: MRUS) (Merus, the Company, we, or our), a clinical-stage oncology company developing innovative, full-length multispecific antibodies (Biclonics and Triclonics), reported the selection of an abstract for a plenary session oral presentation that will highlight interim clinical data on the bispecific antibody petosemtamab in previously treated head and neck squamous cell carcinoma (HNSCC) along with the selection of a second abstract on petosemtamab in advanced gastric/esophageal adenocarcinoma for poster presentation at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2023 taking place in Orlando, Florida April 14-19, 2023 (Press release, Merus, MAR 14, 2023, View Source [SID1234628695]).

About MCLA-158
MCLA-158, or petosemtamab, is an ADCC-enhanced human IgG1 Biclonics designed to bind to cancer stem cells (CSCs) expressing leucine-rich repeat-containing G protein-coupled receptor 5 (Lgr5) and epidermal growth factor receptor (EGFR). In preclinical models, MCLA-158 binding triggers EGFR degradation in LGR5+ CSCs and is designed to have two different mechanisms of action. The first entails blocking of growth and survival pathways in cancer initiating cells. The second exploits the recruitment and enhancement of immune effector cells to directly kill cancer initiating cells that persist in solid tumors and can cause relapse and metastasis.
