About Surufatinib
Surufatinib is a novel, oral angio-immuno kinase inhibitor that selectively inhibits the tyrosine kinase activity associated with vascular endothelial growth factor receptor (VEGFR) and fibroblast growth factor receptor (FGFR), which both inhibit angiogenesis, and colony stimulating factor-1 receptor (CSF-1R), which regulates tumor-associated macrophages, promoting the body’s immune response against tumor cells. Its unique dual mechanism of action may be very suitable for possible combinations with other immunotherapies.

A New Drug Application ("NDA") for surufatinib for the treatment of patients with advanced non-pancreatic NET was accepted for review by the China National Medical Products Administration ("NMPA") and granted Priority Review status in December 2019. A second NDA for surufatinib for the treatment of patients with advanced pancreatic NET has been submitted to the NMPA. We have completed a pre-NDA meeting in the U.S. and received scientific advice in Europe, regarding surufatinib’s respective paths to registration in both geographies. Chi-Med is planning a rolling NDA submission from late 2020 into early 2021 to the U.S. Food and Drug Administration (FDA), followed by a marketing authorization application (MAA) to the European Medicines Agency (EMA) in 2021. In the U.S., surufatinib was granted Fast Track Designations for development in pancreatic and non-pancreatic (extra-pancreatic) NET, and Orphan Drug Designation for pancreatic NET. Additionally, surufatinib is in several late-stage and proof-of-concept trials in China, including in combination with immunotherapies, and proof-of-concept clinical trials in the U.S.

Chi-Med currently retains all rights to surufatinib worldwide.

About Fruquintinib
Fruquintinib is a highly selective and potent oral inhibitor of VEGFR 1/2/3. VEGFR inhibitors play a pivotal role in blocking tumor angiogenesis. Fruquintinib was designed to improve kinase selectivity to minimize off-target toxicities, improve tolerability and provide more consistent target coverage. The generally good tolerability in patients to date, along with fruquintinib’s low potential for drug-drug interaction based on preclinical assessment, suggests that it may be highly suitable for combinations with other anti-cancer therapies.

Fruquintinib was approved for marketing in China by the NMPA in September 2018 and commercially launched by Eli Lilly and Company ("Lilly") in late November 2018 under the brand name Elunate, for the treatment of patients with metastatic colorectal cancer ("CRC"). A Phase III registration study for CRC is being initiated in the U.S., Europe and Japan. A Phase III registration study is also ongoing in China for the treatment of patients with gastric cancer, in combination with paclitaxel. Additionally, fruquintinib is in several other proof-of-concept trials in China and the U.S., including in combination with immunotherapies.

Chi-Med retains all rights to fruquintinib outside of China and is partnered with Lilly in China. Starting October 1, 2020, Chi-Med will be responsible, through its commercial team in oncology of over 320 staff, for the development and execution of all on-the-ground medical detailing, promotion and local and regional marketing activities in China for Elunate. Lilly and Chi-Med will continue to collaborate, as before, in the formulation and execution of national marketing strategy and events in China for Elunate.

On August 24, 2020 Adlai Nortye Ltd. ("Adlai Nortye"), a global clinical-stage biopharmaceutical company reported that the first patient has been dosed in a phase 1b clinical trial (AN0025S0103) to evaluate AN0025, an investigational, potentially first in class oral EP4 antagonist, in combination with Merck’s KEYTRUDA (pembrolizumab) in patients with locally advanced/metastatic solid tumors (Press release, Adlai Nortye Biopharma, AUG 24, 2020, View Source [SID1234563957]).

AN0025S0103 is an open-label, multicenter, phase 1b study in the U.S. and Europe to evaluate the safety and preliminary efficacy of AN0025 in combination with pembrolizumab in patients with locally advanced/metastatic tumors. It will include a dose-limiting toxicity (DLT) observation phase followed by an expansion phase. In the DLT phase, it will enroll patients with urothelial carcinoma of the bladder, or squamous or non-Squamous NSCLC, to assess safety and tolerability. This will be determined whether or not to move on to the expansion phase, which will enroll patients diagnosed with urothelial carcinoma, NSCLC, TNBC, Cervical cancer, and MSS CRC. The first patient was dosed at Huntsman Cancer Institute (HCI) at the University of Utah. In the U.S., the study is also enrolling patients from The University of Texas MD Anderson Cancer Center and The University of Virginia Cancer Center.

All enrolled patients will be treated with AN0025 and pembrolizumab until the patient experiences disease progression, unacceptable toxicity or withdraws consent, or for a maximum of 35 cycles (approximately 2 years). The dose of Pembrolizumab will remain constant at 200 mg every 3 weeks (Q3W) for each dose level of AN0025 and in each cohort.

"In preclinical studies, AN0025 combined with radiotherapy, chemoradiotherapy and with immune checkpoint inhibitors demonstrated antitumor activity in different malignancies. We are optimistic that the combination of AN0025 (EP4 Antagonist) with KEYTRUDA could have meaningful clinical benefit in patients with locally advanced/metastatic solid tumors," said Dr. Lars Birgerson, CDO and CEO of Adlai Nortye USA. "This new combination may provide a new systemic treatment option for many cancer patients, including PD-1/PD-L1 treatment refractory or relapsed patients. We hope to bring innovative cancer treatments to patients with unmet medical needs, to help patients live longer and better."

About AN0025 (EP4 Antagonist)

AN0025 (previously E7046) is an investigational, potentially first in class oral EP4 antagonist that blocks prostaglandin E2 from binding to its subtype 4 receptor (EP4) changing the immunosuppressive character of the tumor microenvironment. Based on preliminary results, it is well tolerated in patients with solid tumors. A Phase 1b study of AN0025 in combination with the standard of care in a neoadjuvant setting for locally advanced rectal cancer showed excellent results, with nearly 40% of patients not requiring surgery or achieving a complete pathological response in the post-surgical specimen in this study.

On August 23, 2020 Genomic Testing Cooperative (GTC) reported that it has launched a joint venture with Hackensack Meridian Health (HMH) that will analyze clinical samples from patients with a variety of different cancers (Press release, Genomic Testing Cooperative, AUG 23, 2020, View Source;utm_medium=rss&utm_campaign=genomic-testing-cooperative-aims-to-expand-clinical-commercial-ngs-access-with-co-op-model [SID1234564047]).

The Irvine, California-based group is building separate reference labs at HMH’s John Theurer Cancer Center (JTCC) in Hackensack, New Jersey and at HMH’s JFK Medical Center in Edison, New Jersey, which will provide complete DNA and RNA profiling services to physicians and hospitals on the East Coast.

GTC CEO Maher Albitar, who previously served as chief medical officer at NeoGenomics, said that academic and small commercial labs often struggle to cover the costs of sequencing samples for clinical research projects. He hopes to minimize the costs of sequencing and improve access to expensive sequencing workflows by cooperating with labs across the US.

GTC’s "co-op" business model consists of two strategies, depending on the partner’s size and financial resources. Smaller labs that cannot afford high-end sequencing instruments send clinical samples to GTC’s CLIA-certified, CAP-approved lab in California, where the firm sequences the samples on its Illumina instruments. GTC then implements algorithms, based on deep-learning and artificial intelligence, to interpret the sequencing data.

For hematology and oncology groups at larger laboratories or hospitals, GTC instead establishes a wet lab with sequencing instruments in their facility to analyze data from inhouse NGS tests. Albitar highlighted that the final report is identical, whether the sequencing portion of the workflow is done at GTC or at the partner’s lab.

Depending on the size of the facility that GTC partners with, Albitar’s team can deliver DNA analysis results within seven days. If the collaborator wishes to include RNA data in the analysis, the firm can produce results in about 10 days.

"Because our partners have a vested interest in this process, we work collaboratively and [make it] less expensive," Albitar said. "For example, they give us access to their clinical data, which makes it easier to find indications, correlations, and validation for our assays than if we were to purchase samples with clinical data from diagnostic labs."

GTC currently offers nine cancer genomic profiling tests that its co-op partners can request, including a liquid biopsy assay developed by partner C2i Genomics. While declining to provide the number of tests that GTC has performed, Albitar said that the firm has seen a 30 percent growth in analyzed samples almost every month since launching in 2018.

Albitar argued that GTC can successfully lower overall sequencing costs that companies often encounter because it increases sample volume gathered from partners. He believes the firm’s model is the first that is based on cooperation, rather than competition, between companies.

"Instead of working in silos and competing with each other, I believe that clinical laboratories should collaborate with each other so that they can deliver better patient care," Albitar explained. "By [using] a collaborative structure, smaller laboratories can have access to the required expertise in NGS and direct access to [an] innovation pipeline in [a] costeffective manner."

While acknowledging that GTC’s services can potentially allow an interested partner to sequence samples for different disease-linked biomarkers, Albitar said that the co-op is currently focusing on sequencing cancer tumor and liquid biopsy samples.

GTC has filed three patents with the US Patent and Trademark Office related to RNA analysis and how RNA can be used for the prediction of clinical behavior of cancers. As part of the model, Albitar noted, every patent the group generates will be shared with the members of the co-op as well. He also highlighted that every member of the co-op has a say in the group’s current and future decisions.

HMH agreement
By signing a contract with HMH, which covers 17 different hospitals and more than 200 patient centers in New Jersey, GTC expects to offer complete DNA and RNA profiling to cancer patients in an efficient and cost-effective manner. The firm will also collaborate with HMH’s data company to get access to clinical data for developing new tests and applications of DNA and RNA sequencing.

Andre Goy, physician-in-chief of oncology at HMH, noted that the group will look at the impact of detected cancer signatures and refine decisions of patient care. For example, HMH clinicians will alter decisions for high-risk lymphoma patients with "standard morphology," who may instead need more intensive therapy. The workflow will also provide his team of clinicians potentially actionable results for rare or difficult-to-treat cancers.

GTC also aims to widen its network of reference labs for genomic testing by opening the facility at HMH to serve as a testing hub on the East Coast, while the California facility will serve the co-op’s interests on the West Coast. The lab will perform NGS testing before providing GTC with the data for downstream analysis.

Albitar noted that the new lab will allow sample collection from the entire health network, as well as support any of GTC’s co-op partners working to push their diagnostic product to the market. However, he emphasized that the facility will not be linked to any of the firm’s existing agreements, especially those related to collaborating oncology practice groups.

For example, Albitar pointed to GTC’s partnership with the JTCC from May, under which the team is building an additional sequencing lab to molecularly profile cancer samples. While the lab will collect cancer samples, the initial JTCC agreement restricted Albitar’s team from collecting them outside the Regional Cancer Care Associates (RCCA) network.

Instead, the new agreement with HMH will allow GTC to separately work with a higher number of physicians outside the RCCA network at HMH as part of the planned reference lab. Goy highlighted that the health network sees roughly 30,000 new cancer patients per year.

Previous collaborations
In addition to the HMH and JTCC joint ventures, GTC previously signed an agreement with C2i Genomics in January to help commercialize the firm’s liquid biopsy tests for solid tumor staging and monitoring. GTC also partnered with Cellgen Diagnostics in 2019 to offer companion diagnostic development for cancer immunotherapy developers.

GTC will use the HMH collaboration to help build a network of reference labs across the country. The firm will aggregate sequencing data from the network — which Albitar said will be standardized by applying the same methods and tools — into a database that it hopes will form the basis of future research for improving precision medicine.

Instead of raising private capital, GTC relies on profits shared with the different members of the co-op. However, Albitar noted that his team welcomes strategic investors who will add and contribute to its growth, "especially if these investors are members of the co-op."

"With this cooperative information, we are sharing the science and medicine, but at the same time, it is democratizing the technology so that other labs — instead of investing a lot of money in a specialized team — are relying on teams that we have centrally at GTC," Albitar said. "At the same time, we are sharing the project with them, and as part of the cooperative concept, we are also sharing profits with sources."

On August 23, 2020 Kazia Therapeutics Limited (ASX: KZA;NASDAQ: KZIA), an Australian oncology-focused biotechnology company, reported that the United States Food and Drug Administration (FDA) has granted Orphan Drug Designation (ODD) to Kazia’s paxalisib (formerly GDC-0084) for the treatment of malignant glioma, which includes Diffuse Intrinsic Pontine Glioma (DIPG), a rare and highly aggressive childhood brain cancer (Press release, Kazia Therapeutics, AUG 23, 2020, View Source [SID1234563958]).

Key Points

Orphan Drug Designation (ODD) is a special status accorded to drugs which are considered promising potential treatments for rare (‘orphan’) diseases, generally defined as those which affect less than 200,000 cases per annum in the United States
ODD can provide drug developers with up to seven years of Orphan Drug Exclusivity (ODE), extending the effective life of a commercial product. It also provides opportunities for grant funding, protocol assistance, and financial benefits, such as a waiver of New Drug Application fees, and tax credits
Receipt of ODD follows award of Rare Pediatric Disease Designation (RPDD) for DIPG on 7 August 2020
Kazia CEO, Dr James Garner, commented, "Taken together, RPDD and ODD provide a powerful suite of incentives, opportunities, and protections for the development of paxalisib in DIPG. We look forward to seeing initial data from the ongoing phase I study in DIPG at St Jude Children’s Research Hospital during the second half of calendar 2020. In parallel, we are working closely with collaborators, advisors, and researchers to determine the best path forward for paxalisib in this devastating disease."

He added, "This award of ODD concludes a program of regulatory optimisation that Kazia has initiated for paxalisib over the past six months. As we orient paxalisib towards commercialization, these special designations from FDA will allow us to move forward in the swiftest and most effective way possible."

Orphan Drug Designation

ODD exists to recognise the development of a drug for a rare disease, which may affect adults or children. ODD provides an additional period of 7.5 years data exclusivity (for a paediatric disease), which allows companies to better defend their products against competition. It also results in a waiver by FDA of fees for a marketing application, under the Prescription Drug User Fees Act (PDUFA fees), which are just under US$ 3 million in FY2020. In addition, drugs with ODD may be eligible for orphan grants by FDA.

Kazia previously received ODD for paxalisib in glioblastoma in February 2018.
