"Generated from our proprietary Lambda-capTM and MATCHTM technology platform, NM32 represents a T-cell engager designed to help the patient’s immune system recognize and attack tumor cells. ROR1 is overexpressed on a wide spectrum of highly prevalent solid tumor indications but has very limited expression on normal tissue, making it an optimal antigen for a CD3 engager," said David Urech, Ph.D., Founder and Chief Executive Officer of Numab Therapeutics.

"We are pleased to start NM32’s clinical development path enabling us to potentially bring this novel therapy to patients with advanced solid tumors who are in need of treatment options that provide durable anti-tumor activity with a tolerable safety profile. Enrollment is progressing nicely, with patients completing the first treatment cycle of the initial dose level", commented Martin Stern, Senior Vice President Clinical Science at Numab Therapeutics. "Despite the introduction of checkpoint inhibitors and several commercially available CD3 engagers for the treatment of hematological malignancies, there has been limited success in solid tumors mainly due to the lack of highly tumor-specific antigens allowing selective T-cell activation against tumor cells."

This multi-center Phase 1 study of NM32 is a dose-escalation trial to characterize the pharmacokinetic properties, pharmacodynamic effects and safety profile of NM32 and to select an optimal dosing regimen for further clinical development. It is planned to enroll up to 60 patients with solid tumors overexpressing ROR1 from major clinical sites across the United States. Generated preclinical data in non-human primates indicate a high potency and an excellent safety profile.

About NM32 (NM32-2668)
NM32 is a next generation tri-specific immuno-oncology drug targeting the receptor tyrosine kinase-like orphan receptor 1 (ROR1) and the T-cell receptor associated antigen CD3. The third domain targets serum albumin to provide half-life extension to allow convenient bi-weekly dosing. T-cell redirection using CD3 engagers is an established treatment modality showing high response rates and durable activity in hematological malignancies and has more recently also shown promising results for selected targets overexpressed in solid tumors. ROR1 is a clinically validated tumor associated antigen with overexpression in several indications with high unmet need including lung, breast, ovarian, endometrial, renal and gastric cancer and limited expression on healthy tissue.

On October 30, 2024 SynOx Therapeutics Limited ("SynOx"), a late clinical-stage biopharmaceutical company developing a novel treatment for CSF-1 related and macrophage-driven disorders, reported that it has raised additional funding in a final close of its Series B financing (Press release, SynOx Therapeutics, OCT 30, 2024, View Source [SID1234647546]). The Series B extension was led by new investor Gilde Healthcare and brings the total capital raised by SynOx in the round to $92 million including earlier investments from Forbion, HealthCap and Bioqube Ventures. Proceeds from the financing are supporting a registrational Phase 3 clinical trial of emactuzumab, a potentially best-in-class CSF-1 receptor (CSF-1R) inhibiting monoclonal antibody for the treatment of Tenosynovial Giant Cell Tumour (TGCT).

In conjunction with the closing of the Series B extension, SynOx reported that the first patients have been dosed in its Phase 3 registrational study of emactuzumab. The study, named TANGENT, is a global, multi-centre, randomized, double-blind, placebo-controlled Phase 3 trial designed to evaluate the efficacy and safety of emactuzumab in patients with TGCT. The study’s primary outcome measure is overall response rate (ORR). Investigators will also assess several secondary outcomes including functional and quality of life measurements, impact on tumour volume, and duration of response. Investigators expect to enrol approximately 130 patients in the trial. Additional study details can be found on ClinicalTrials.gov (Identifier: NCT05417789).

TGCT is a rare, non-malignant but aggressively growing tumour of the synovium, primarily located in knee, hip, and ankle joints and caused by excessive production of CSF-1. It is a chronically debilitating disease for patients causing loss of function of the affected joints, pain, stiffness and limited range of motion. Emactuzumab specifically inhibits CSF-1R and earlier clinical work in TGCT1 showed it to be a highly effective, next-generation therapy with a short treatment cycle, rapid onset of action and long duration of response.

"We are pleased to add Gilde Healthcare to our impressive investor syndicate and are appreciative for their support of our team and our vision for the potential of emactuzumab to address the unmet needs, and improve the quality of life, of TGCT patients around the world," said Ray Barlow, Ph.D., Chief Executive Officer of SynOx. "The dosing of patients in the TANGENT trial marks an important milestone for SynOx and is a testament to the dedication and hard work of our team. We look forward to efficiently conducting this study and continuing to pursue our goal of advancing emactuzumab toward market for TGCT patients in desperate need of new treatment options."

As part of the Series B extension, Arthur Franken, general partner at Gilde Healthcare, will join the SynOx Board of Directors. Mr. Franken brings more than two decades of venture and growth capital investment expertise, including several public listings and trade sales.

"We are pleased to join SynOx as an investor and help support the late-stage development of emactuzumab, which we believe has a best-in-class profile as a CSF-1R targeted antibody. Importantly, we also believe that the SynOx team is well positioned to successfully complete clinical development of emactuzumab and deliver this important treatment option to TGCT patients," said Mr. Franken.

On October 30, 2024 SynOx Therapeutics Limited ("SynOx" or the "Company"), the late-stage clinical biopharmaceutical company developing emactuzumab for the treatment of Tenosynovial Giant Cell Tumour (TGCT) and other diseases, reported it has entered into a $35m loan facility with Hercules Capital, Inc. (NYSE:HTGC) ("Hercules") (Press release, SynOx Therapeutics, OCT 30, 2024, View Source [SID1234647545]).

The transaction strengthens the Company’s balance sheet as it executes TANGENT, a registrational Phase 3 study of emactuzumab, SynOx’s potentially best-in-class CSF-1(R) inhibiting monoclonal antibody (mAb) for the treatment of TGCT.

This loan facility provides SynOx with flexibility to fund additional clinical work in TGCT to augment TANGENT, activities to support the successful registration and commercialisation of emactuzumab in TGCT, and potentially to explore the use of emactuzumab in other CSF-1 driven and macrophage-mediated diseases.

The term loan facility provides up to $35m, in total, in four tranches. The initial tranche was drawn on signing, with subsequent tranches available over the medium term and upon achievement of certain clinical milestones.

Ray Barlow, Chief Executive Officer of SynOx Therapeutics, said: "This funding will provide SynOx with additional capital to fulfil its mission of establishing emactuzumab as a best-in-class drug, to address significant unmet medical needs and greatly improve the quality of life for as many patients as possible. We are grateful for the support from Hercules, which together with the $75m we raised recently in our Series B round, puts SynOx on a strong financial footing."

R. Bryan Jadot, Senior Managing Director and Group Head – Life Sciences, Hercules, said: "We have been impressed by the quality of data SynOx has already generated on emactuzumab, which demonstrate it to be highly differentiated from other CSF-1 inhibiting drugs in development. Emactuzumab is showing great promise in treating TGCT, and we believe it has the potential to treat other related conditions as well."

TGCT is a type of tumour that affects the soft tissue lining of joints and tendons. It is a highly debilitating disease that often impacts large, important joints such as the knee, hip and ankle. It seriously impacts quality of life by causing significant pain and stiffness in affected joints and limiting range of motion. While most patients receive surgical intervention, more than 50% of patients with diffuse disease experience tumour recurrence within three years of surgery [1].

Emactuzumab, a novel next-generation CSF-1R mAb with a potentially best-in-class profile, has demonstrated substantial clinical activity in earlier clinical work in TGCT [2], with an objective response rate (ORR) of 71%, rapid and robust tumour reduction, a long duration of effect, significant improvements in functional ability, good tolerability and a manageable safety profile. The Phase 3 TANGENT trial will assess its safety and efficacy in patients with localized and diffuse TGCT.
