About Radiohybrid Prostate‐Specific Membrane Antigen (rhPSMA)
rhPSMA compounds are referred to as radiohybrid ("rh"), as each molecule possesses four distinct domains. The first consists of a Prostate‐Specific Membrane Antigen‐targeted receptor ligand. It is attached to two labelling moieties which may be radiolabeled with diagnostic isotopes such as 18F or 68Ga for PET imaging, or with therapeutic isotopes such as 177Lu or 225Ac for radioligand therapy, all of which are joined together by a modifiable linker which can be used to modulate important pharmacokinetic characteristics. Radiohybrid PSMA offers the potential for targeted treatment for men with prostate cancer and originated at the Technical University of Munich, Germany. Blue Earth Diagnostics acquired exclusive worldwide rights to rhPSMA diagnostic imaging technology from Scintomics GmbH in 2018, and therapeutic rights in 2020, and has sublicensed the therapeutic application to its sister company Blue Earth Therapeutics.

On October 30, 2024 Aitia, a biotech company pioneering the use of causal AI and Digital Twins in drug discovery and development, reported that it is expanding its collaboration with Servier, a global and independent pharmaceutical company, to tackle gliomas, a broad group of brain cancers (Press release, Servier, OCT 30, 2024, View Source [SID1234647550]). This collaboration aims to use Aitia’s breakthrough technology which is powered by millions of data points from patient cancer tissues to find new treatments for this deadly disease.

Under the terms of the collaboration, Aitia and Servier will work together to discover and, validate novel drug targets and develop novel drug candidates for glioma using Aitia’s Gemini Digital Twins and Servier’s therapeutic discovery and clinical development expertise in oncology. This collaboration will include exploration of the heterogeneous biology of these brain cancers, mechanisms of resistance, and drug response at the individual patient level. In a recent breakthrough in another form of glioma, specifically Grade 2 astrocytoma or oligodendroglioma with a susceptible IDH1 or IDH2 mutation following surgery including biopsy, sub-total resection, or gross total resection in adult and pediatric patients 12 years and older, Servier recently announced approval of the brain cancer drug, VORANIGO, the first approved drug for this disease area in almost 25 years.

Gliomas, tumors that originate in the brain or spinal cord from glial cells, affects more than 190,000 people worldwide annually. The most aggressive form of glioma, glioblastoma, has an average survival time after diagnosis of approximately 15 months, with less than 7% of patients surviving beyond five years, according to the National Brain Tumor Society. Despite standard treatments like surgery, radiation and chemotherapy, glioblastoma has a high rate of recurrence and there are currently no curative therapies.

"We are excited to expand our collaboration with Aitia into gliomas as we continue to prioritize brain cancer after our recent positive results and approval of VORANIGO in the US and in growing number of territories," said Fabien Schmidlin, Global Head of Translational Medicine at Servier. "At Servier, we are committed to advancing therapies for cancer patients with high unmet medical needs, and we believe that integrating Aitia’s Gemini Digital Twins with our expertise in oncology, particularly in targeting molecular mutations, could open new avenues for more effective treatments."

"Glioma is the among the deadliest forms of cancer, and the lack of broadly effective treatments highlights the urgent need for new approaches that leverage the growth of genetic and multi-omic patient data and breakthroughs in AI," said Colin Hill, CEO and co-founder of Aitia. "We believe that our Gemini Digital Twins, along with Servier’s drug discovery and clinical development expertise in hard-to-treat cancers can lead to new breakthrough therapies for this disease."

This collaboration represents the fourth area of research Aitia and Servier are collaborating on. The companies began their partnership in 2022, to advance drug discovery, translational, and clinical development efforts in Multiple Myeloma, then expanding in 2023 to include drug discovery and development for pancreatic cancer, and again in January 2024 to discover patient responders for Servier’s LRRK2 inhibitor in Parkinson’s disease.

Aitia’s approach centers on two key innovations: causal AI and Gemini Digital Twins. Causal AI goes beyond correlative associations to identify which genetic or molecular changes drive diseases and patient response to therapies. Gemini Digital Twins are virtual models that are reverse-engineered from huge quantities of genetic, multi-omic, and clinical data from patients that reveal how genes, proteins, and other molecules interact within cells and tissues to drive clinical outcomes. These Gemini Digital Twins of a specific disease allow researchers to rapidly test billions of experiments such as gene and protein knockdowns or application of a drug candidate in a human patient context versus animal models or cells in petri dishes. These high-throughput "virtual experiments" in patient-derived Gemini Digital Twins leads to discovering and selecting drug candidates that are more likely to succeed in clinical trials in specific patient populations.

On October 30, 2024 Akeso Biopharma (9926.HK) reported the enrollment of the first patient in its randomized, controlled, multicenter Phase III clinical study (AK117-302) for head and neck squamous cell carcinoma (Press release, Akeso Biopharma, OCT 30, 2024, View Source [SID1234647549]). This trial evaluates the innovative PD-1/VEGF bispecific antibody ivonescimab in combination with Akeso’s next-generation CD47 monoclonal antibody ligufalimab (AK117) against pembrolizumab for the first-line treatment of PD-L1 positive (CPS≥1) recurrent/metastatic squamous cell carcinoma of the head and neck (R/M HNSCC).

The AK117-302 study represents a significant milestone as the first Phase III clinical trial globally to investigate a CD47 monoclonal antibody therapy for solid tumors. This trial is the fifth Phase III study for ivonescimab, utilizing PD-1/L1 monoclonal antibody therapy as a positive control, and the third Phase III study comparing ivonescimab with pembrolizumab. The AK117-302 trial underscores Akeso’s commitment to advancing the field of cancer immunotherapy and establishing a global standard of care for cancer treatment. Furthermore, it highlights our capability to maximize the number of cancer patients globally that can benefit from our product portfolio through a strategic approach to clinical development.

In 2022, there were 770,000 new cases of head and neck cancer globally, with 84,000 cases reported in China. Squamous cell carcinoma of the head and neck (HNSCC) accounts for over 90% of these cancers. Unfortunately, the five-year survival rate for patients with recurrent/metastatic HNSCC (R/M HNSCC) is just 3.6%. While targeted therapies and immunotherapies have improved treatment options, the median overall survival (OS) remains below one year.

Pembrolizumab has emerged as the first-line standard treatment for R/M HNSCC and is recommended in both CSCO and NCCN guidelines. There is a critical unmet need for more effective therapies to help HNSCC patients achieve long-term survival.

At the 2024 European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress, Akeso reported initial positive data on its combination therapy of ivonescimab and ligufalimab. This combination demonstrated significant tumor reduction and survival benefits, particularly for HNSCC patients, who require rapid tumor shrinkage. The preliminary efficacy data from this therapy surpassed that of previously disclosed PD-1 studies, positioning it as a potentially new immunotherapy option for HNSCC patients.

About Ligufalimab (AK117)

AK117, independently developed by Akeso, is a next-generation humanized lgG4 anti-CD47 antibody without hemagglutination effect. AK117 can bind to CD47 expressed on tumor cells and block the interaction between CD47 and SIRPα, in order to enhance the phagocytic activity of phagocytes on tumor cells, thereby inhibiting the growth of tumors.

Currently, several phase II clinical trials are underway to investigate the potential of AK117 in combination with azacitidine for hematological tumors, as well as AK117 alone or in combination with ivonescimab and cadonilimab for various solid tumors. Preliminary studies have shown promising efficacy and safety profiles, with no observed dose-limiting toxicity events. Additionally, the Chinese Phase II clinical study of the first-line treatment for unfit AML using AK117 in combination with venetoclax and zzacitidine, as well as the international multicenter Phase II clinical study of AK117 for treating MDS, are both ongoing with patient enrollment.

About Ivonescimab (AK112/SMT112)

Ivonescimab is a novel global first-in-class PD-1/VEGF bi-specific immunotherapy drug independently developed by Akeso. Ivonescimab is known as SMT112 in Summit Therapeutics’s license territories, including the United States, Canada, Europe, Japan, Central America, South America, the Middle East and Africa. Ivonescimab was granted marketing approval by NMPA for the treatment of EGFR mutated locally advanced or metastatic non-squamous NSCLC patients who have progressed after EGFR TKI treatment. Currently, ivonescimab’s first indication has been approved in China, and Akeso is conducting 6 registrational trials versus anti-PD-1/L1 therapeutics. Akeso is also conducting multiple clinical trials of ivonescimab covering 17 indications including gastrointestinal cancer, hepatocellular carcinoma and colorectal cancer.

On October 30, 2024 HOOKIPA Pharma Inc. (NASDAQ: HOOK) ("HOOKIPA" or the "Company"), a clinical-stage biopharmaceutical company developing next generation immunotherapeutics for the treatment of cancer and serious infectious diseases, reported that researchers at Memorial Sloan Kettering Cancer Center (MSKCC) have dosed the first patients in an investigator initiated trial (IIT) of eseba-vec, HOOKIPA’s human papillomavirus type 16 (HPV16+)-targeted investigational immunotherapeutic agent, in patients with minimal residual disease positive (MRD+) HPV-driven head and neck cancer (Press release, Hookipa Pharma, OCT 30, 2024, View Source [SID1234647548]).

"Based on the positive Phase 2 data generated to date in recurrent/metastatic (R/M) HNSCC, we believe eseba-vec has broad potential across HPV16+ cancers. We are enthusiastic to explore the potential of eseba-vec as an adjuvant treatment for patients with locally advanced HNSCC and continue our collaboration with Drs. Wong and Ho and the team at MSKCC," said Mark Winderlich, PhD, Chief Research and Development Officer at HOOKIPA. "We believe eseba-vec can help address unmet needs within the adjuvant setting and pave the way for us to help more patients with HNSCC."

Malte Peters, Chief Executive Officer of HOOKIPA added, "Eseba-vec was well tolerated and has demonstrated compelling efficacy in combination with pembrolizumab in HPV+ (R/M) HNSCC. We look forward to building on these promising findings with the expansion into adjuvant care. Our eseba-vec clinical development program in HNSCC continues to advance and we are on track to initiate our pivotal AVALON-1 Phase 2/3 study in the front-line setting for patients with HPV16+ oropharyngeal squamous cell carcinoma (OPSCC) in the fourth quarter of 2024. We expect initial safety and efficacy data from the IIT in 2026."

Winston Wong, MD, commented, "Targeted immunotherapeutic agents can play an important role in the care of patients with HPV16+ HSNCC. I am encouraged by the potential for eseba-vec in this setting based on promising Phase 2 combination data with pembrolizumab in the first line setting presented at this year’s American Society for Clinical Oncology annual meeting showing rapid and durable activation of antigen-specific CD8+ T cells and promising clinical response rates, especially in the CPS 20 or higher subgroup. Patients who are HPV16+ after receiving standard of care treatment for curative intent may also benefit from an immunotherapy treatment and we are currently testing whether eseba-vec may be a new, effective adjuvant treatment option."

The Phase 2, randomized, double-blind, placebo-controlled study (NCT06373380) will evaluate the use of eseba-vec in patients with minimal residual disease positive (MRD+) HPV-driven head and neck cancer. The primary endpoint of the study is disease-free survival. Secondary endpoints include an assessment of safety and tolerability. The study is expected to enroll approximately 50 patients.

About eseba-vec
Eseba-vec (also known as HB-200) is an investigational immunotherapeutic agent being evaluated for HPV16 positive cancers. The first indication for eseba-vec is for the potential treatment of patients with HPV16+ recurrent/metastatic oropharyngeal squamous cell carcinoma (R/M OPSCC) with a PDL1 CPS of 20 or higher, in combination with pembrolizumab, in the first line (1L) setting. Eseba-vec has received Fast Track Designation from the U.S. Food and Drug Administration and PRIME designation from the European Medicines Agency for the treatment of 1L HPV16+ OPSCC. Eseba-vec was developed using HOOKIPA’s proprietary arenavirus platform.

On October 30, 2024 Numab Therapeutics AG ("Numab") reported the start of a Phase 1 clinical trial evaluating NM32, a next generation tri-specific immuno-oncology therapeutic targeting the receptor tyrosine kinase-like orphan receptor 1 (ROR1) and the T-cell receptor associated antigen CD3 (Press release, Numab, OCT 30, 2024, View Source [SID1234647547]). The third binding moiety of NM32 targets serum albumin to provide half-life extension allowing for convenient bi-weekly dosing and to keep the lower molecular weight than immunoglobulin enabling efficient tumor penetration.

"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.
