Even though lung cancer is the second most common cancer and leading cause of cancer death globally, NSCLC patients with EGFR exon20ins mutation lack effective treatment options, especially those who develop brain metastases (BM) historically have worse outcomes. Sunvozertinib (DZD9008), which was granted Breakthrough Therapy Designation by both the US FDA and China CDE, is a rationally designed, oral, potent EGFR exon20ins inhibitor, with wild-type EGFR selectivity.

The topline result presented at 2022 ESMO (Free ESMO Whitepaper) was based on the latest data from WU-KONG6 study, the multicenter, single-arm, Phase II pivotal study conducted in China. As of 31 July 2022, the efficacy set included 97 platinum-pretreated NSCLC patients with EGFR exon20ins mutations. Key findings from efficacy set are as follows:

Parameter

Results in 300 mg cohort (N=97)

Confirmed ORR per BICR

59.8% (58/97)

Confirmed ORR in patients with baseline brain
metastasis per BICR

48.4% (15/31)

*Patients are still on treatment and responding.

Sunvozertinib also demonstrated a favorable safety profile. Of all 277 patients in the safety set, the most common treatment-related adverse events (TEAE) were diarrhea and rash, the majority of which were Grade 1/2 and clinically manageable.

"The importance of advancing research on NSCLC with EGFR exon20ins mutation – a complicated and devastating disease – cannot be overstated, as available treatment options provide limited benefit especially to those develop brain metastasis," said Dr. Xiaolin Zhang, CEO of Dizal, "It is great news to our patients that sunvozertinib is showing such strong antitumor activities with a benign safety profile. This data further strengthens our confidence in sunvozertinib and reinforces its best-in-class position"

About sunvozertinib (DZD9008)

Sunvozertinib was designed with the goal to address the limitations of existing NSCLC therapies. It is an irreversible inhibitor targeting EGFR exon 20 insertion mutations as well as EGFR sensitizing T790M and uncommon mutations while maintaining selectivity against wild-type EGFR. The first pivotal study WU-KONG6 of sunvozertinib has achieved its primary endpoint, demonstrating superior antitumor efficacy in pre-treated NSCLC patients with EGFR exon20 insertion mutations. The confirmed ORR (cORR) at 300 mg was 59.8% by BICR. Patients with baseline brain metastasis showed significant response as well, with a confirmed ORR of 48.4%. (Data cut-off date: July 31, 2022). It is well tolerated with a manageable AE profile. Global pivotal studies are ongoing for ≥ 2nd line and 1st line treatment of NSCLC with EGFR exon20 insertion mutation in countries including China, U.S., EU, Australia, South Korea and other countries and regions.

About EGFR Exon20ins

Lung cancer is the leading cause of cancer death in the world. It is classified broadly as non-small cell lung cancer (NSCLC), accounting for 85% lung cancer cases, and small cell lung cancer (SCLC). EGFR mutation is common in NSCLC. About 4–12% of all EGFR mutations are insertions at exon 20 (EGFR exon20ins). Patients with EGFR exon20ins generally don’t respond to the first-, second- and third-generation EGFR tyrosine kinase inhibitors (TKIs).

On September 5, 2022 Bertis, a proteomics-based precision medicine technology development company (CEOs Dong-young Noh, Seung-man Han), reported on the 5th that the research results of their search for protein biomarkers for early diagnosis of high-grade serous ovarian cancer (HGSOC) were published in the September issue of the international scientific journal, Journal of Proteome Research (Press release, Bertis, SEP 5, 2022, View Source [SID1234619000]).1

Ovarian cancer is the first leading cause of death among gynecological cancers. Most patients are asymptomatic in early stages, and as effective early diagnosis methods have not yet been secured, 70% of the cases are not detected until the cancer develops into stage 3 or higher.2, 3 After stage 3, the survival rate of the patient is drastically reduced. The 5-year survival rate is more than 76% in stage 1 and approximately 60% to 74% in stage 2, while the 5-year survival rate in early stage 3 is known to be 41%, 23% in late stage 3, and just 11% in stage 4.4 In particular, HGSOC is the most common type of ovarian cancer, accounting for 70% of all ovarian cancers. For decades, the overall survival rate of HGSOC has barely improved, and the need for the introduction of a standard testing method for early diagnosis has been emphasized.5, 6

The research team at Bertis presented a new multi-biomarker panel candidate with 95% accuracy (100% sensitivity, 91% specificity) for the diagnosis of stage 1 to 3 HGSOC. The results of this research were published in the September issue of the Journal of Proteome Research on the 2nd by the American Chemical Society. In particular, the results were included as one of the supplementary cover articles in this issue with 16 papers listed.

In this study, the research team identified 18 candidate proteins after quantifying 1,847 serum proteins, the highest number ever reported as ovarian cancer biomarker research results, through Bertis’ technology platform to discover biomarker candidates. As a result of developing and evaluating a predictive model, the accuracy of the diagnostic value for stages 1 to 37 HGSOC was 95% (sensitivity 100%, specificity 91%) when 18 candidate proteins were combined with multiple biomarkers.

Un-beom Kang, Head of Bertis Biomarker Research Institute, who led this study, explained, "This study is significant in that it secured the results of in-depth blood proteome research based on Bertis’ advanced proteomics analysis technology, as well as presented a new biomarker panel with high accuracy for ovarian cancer," and added that, "We expect that based on data from this study, research and development to provide standardized testing for early diagnosis of ovarian cancer will be expedited and the creation of results will be accelerated."

"Proteomics analysis is an incredibly effective tool for understanding cancer and discovering new biomarkers for diagnosis and prognosis," said, Seung-man Han, Bertis’ CEO. "As a company that has led the discovery of biomarkers based on proteomics technology as well as the development of clinical solutions using it, we will do our best to contribute to the improvement of the diagnosis and treatment of major diseases through continuous research and development."

Bertis is a company that combines proteomics and bioinformatics to develop biomarkers for cancer and other various major diseases, as well as provides diagnosis and analysis solutions. It succeeded in commercializing proteomics technology with Mastocheck, the world’s first proteomics-based blood testing solution for early breast cancer diagnosis, and PASS (Pan-omics Analysis Service & Solution), an integrated analysis solution for Panomics. Currently, Bertis is researching and developing early diagnosis solutions for pancreatic cancer, ovarian cancer, etc.

On September 5, 2022 Avacta Group plc (AIM: AVCT), a clinical stage oncology drug company and developer of powerful diagnostics based on its innovative Affimer and pre|CISION platforms, reported that the US Food and Drug Administration (FDA) has granted Orphan Drug Designation (ODD) to the company’s lead pre|CISION drug candidate, AVA6000, for treatment of soft tissue sarcoma (Press release, Avacta, SEP 5, 2022, View Source [SID1234618997]).

AVA6000 is a form of the generic chemotherapy doxorubicin that has been modified using the pre|CISION technology so that it is activated predominantly in the tumour with the aim of sparing healthy tissue from exposure and improving the safety, tolerability and efficacy of the drug. Doxorubicin has a market size that is expected to grow to $1.38bn by 2024, and is widely used as part of the standard of care in several cancer types. Avacta has an ongoing Phase 1 clinical trial to assess the safety and pharmacokinetics of AVA6000 which has potential as a treatment for patients with a range of cancer types, including soft tissue sarcoma.

The FDA can grant ODD based on a review of preclinical data from investigational treatments for rare diseases, such as soft tissue sarcoma, which are defined as conditions affecting fewer than 200,000 people in the US. This designation qualifies the developer of the drug for certain incentives, including, seven years of market exclusivity upon drug approval from the FDA.

Soft-tissue sarcoma is a rare mesenchymal malignancy which accounts for less than 1% of all adult tumours. Despite the successful advancement of localised therapies, such as surgery and radiotherapy, these tumours can recur, often with metastatic disease. The American Cancer Society estimates that, in 2022 approximately 13,190 new soft tissue sarcomas will be diagnosed, and about 5,130 people are expected to die of the disease in the US.

Dr Alastair Smith, Chief Executive Officer of Avacta, commented: "We are delighted to receive Orphan Drug Designation from the FDA for AVA6000, which is a reflection of the high quality of the preclinical data and the potential benefit the pre|CISION platform can bring to cancer patients."

"This designation provides tax credits and other incentives for drug developers addressing rare diseases. Most notably the Orphan Drug Designation will give Avacta, if AVA6000 is approved for treatment of soft tissue sarcoma, seven years of market exclusivity in the US, which is a significant commercial advantage."

About Lacutamab:

Lacutamab (IPH4102) is a first-in-class anti-KIR3DL2 humanized cytotoxicity-inducing antibody that is currently in clinical trials for treatment of cutaneous T-cell lymphoma (CTCL), an orphan disease, and peripheral T cell lymphoma (PTCL). Rare cutaneous lymphomas of T lymphocytes has a poor prognosis with few efficacious and safe therapeutic options at advanced stages.

KIR3DL2 is an inhibitory receptor of the KIR family, expressed by approximately 65% of patients across all CTCL subtypes and expressed by up 90% of patients with certain aggressive CTCL subtypes, in particular, Sézary syndrome. It is expressed by up to 50% of patients with mycosis fungoides and peripheral T-cell lymphoma (PTCL). It has a restricted expression on normal tissues.

About ANKET:

ANKET (Antibody-based NK cell Engager Therapeutics) is Innate’s proprietary platform for developing next-generation, multi-specific natural killer (NK) cell engagers to treat certain types of cancer.

This versatile, fit-for-purpose technology is creating an entirely new class of molecules to induce synthetic immunity against cancer. It leverages the advantages of harnessing NK cell effector functions against cancer cells and also provides proliferation and activation signals targeted to NK cells.

Our latest innovation, the tetra-specific ANKET molecule, is the first NK cell engager technology to engage activating receptors (NKp46 and CD16), a tumor antigen and an interleukin-2 receptor (via an IL-2 variant, IL-2v) via a single molecule.

About Monalizumab:

Monalizumab is a potentially first-in-class immune checkpoint inhibitor targeting NKG2A receptors expressed on tumor infiltrating cytotoxic CD8+ T cells and NK cells.

NKG2A is an inhibitory checkpoint receptor for HLA-E. By expressing HLA-E, cancer cells can protect themselves from killing by NKG2A+ immune cells. HLA-E is frequently overexpressed in the cancer cells of many solid tumors and hematological malignancies. Monalizumab may reestablish a broad anti-tumor response mediated by NK and T cells, and may enhance the cytotoxic potential of other therapeutic antibodies1.

The ongoing development for monalizumab is focused on investigating monalizumab in various combination strategies in different malignancies, including, in early lung cancer, the Phase 3 PACIFIC-9 study in adults with locally advanced (Stage III), unresectable NSCLC, who have not progressed following platinum-based concurrent chemoradiotherapy, and the Phase 2 NeoCOAST-2 study in the neoadjuvant early-stage setting of NSCLC.

On September 5, 2022 Synthetic Biologics, Inc. (NYSE American: SYN), a diversified clinical-stage company developing therapeutics designed to treat diseases in areas of high unmet need, reported a presentation of initial data from a Phase 1 investigator-sponsored study evaluating VCN-01 in combination with durvalumab for patients with recurrent/metastatic squamous cell carcinoma of the head and neck (R/M HNSCC) (Press release, Synthetic Biologics, SEP 5, 2022, View Source [SID1234618995]). Data will be featured in a poster presentation at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress, being held both virtually and in Paris from September 9-13, 2022.

"We are encouraged by the acceptable safety profile seen in the sequential arm of this study as well as the biological activity observed in R/M HNSCC patients previously treated with anti-PD(L)-1 agents, which speak to the promise of VCN-01-based combination approaches for devastating cancers with high unmet need," said Manel Cascallό, Ph.D., General Director of Synthetic Biologics’ European Subsidiary. "Further, these results provide valuable dose-finding context and build upon our compelling foundation of data that highlight VCN-01’s differentiated mechanism of action that may transform cancer therapy. We look forward to leveraging our findings as we advance VCN-01 through clinical development and we remain on track to deliver on several value-driving milestones, including the initiation of our Phase 2 study in patients with metastatic pancreatic adenocarcinoma in the fourth quarter of 2022 and our Phase 2/3 study in retinoblastoma in the second half of 2023."

Key data and conclusions featured in the ESMO (Free ESMO Whitepaper) presentation include:

Safety: Treatment with VCN-01 had an acceptable safety profile when administered with durvalumab in the sequential regimen (single dose of VCN-01 administered 14 days prior to the first dose of durvalumab; n=14).
The most common treatment-related adverse events (TRAEs) were pyrexia, flu-like symptoms and increases in liver transaminases.
TRAEs were dose-dependent, reversible and consistent with TRAEs previously described for other adenovirus-based products.
Pharmacokinetics (PK) and pharmacodynamics (PD): Based on toxicology and PK/PD analysis the recommended Phase 2 dose is 1×1013 viral particles (vp)/patient.
Biological activity: Sustained blood levels of VCN-01 viral genomes and increased serum hyaluronidase levels were maintained for over six weeks.
Observed an increase in CD8 T cells, a marker of tumor inflammation and an upregulation of PD-L1 in tumors.
Analysis of serial tumor biopsies revealed differential gene expression profiles and downregulation of matrix-related pathways after VCN-01 administration.
