Key Points

Evotec has granted Kazia an exclusive global worldwide license to develop, manufacture, and commercialise EVT801 in all territories and indications.
Under the terms of the agreement, Kazia will pay an immediate upfront of €1 million (AU$ 1.6 million), contingent milestones of up to €308 million (AU$ 480 million) related to achievement of clinical, regulatory, and commercial outcomes over the lifetime of the drug, and a tiered single-digit royalty on net sales.
Evotec is a leading drug discovery and development company, headquartered in Hamburg, Germany, and listed on the Frankfurt Stock Exchange.
EVT801 is a small-molecule inhibitor of VEGFR3. Its primary activity is to inhibit lymphangiogenesis, the formation of new lymphatic vessels around a growing tumour. By doing so, EVT801 is expected to starve the tumour of vital nutrients and to reduce metastasis. EVT801 also has marked activity on the immune system within the tumour and may therefore enhance the activity of immuno-oncology therapies.
Kazia and Evotec have also entered into a master services agreement, under which the two companies will collaborate closely on the further development of EVT801.
EVT801 was originally discovered by Sanofi (NASDAQ: SNY), the largest pharmaceutical company in France and among the five largest in the world and was developed through a partnership between Sanofi and Evotec.
Kazia expects to launch a phase I clinical trial in CY2021. The initial exploratory indications for EVT801 include renal cell carcinoma (kidney cancer), hepatocellular carcinoma (liver cancer), and soft tissue sarcoma.
Kazia CEO, Dr James Garner, commented, "We are delighted to add this tremendously exciting new compound to the Kazia pipeline. Evotec have done first-class work in the early development of EVT801, and the preclinical data package is exceptionally strong. We intend to fast track a phase I clinical trial of the drug, which we expect to commence in CY2021."

He added, "As we have built Kazia over the past five years, our strategy has been to assemble a portfolio of world-class development candidates through in-licensing. The EVT801 transaction is wholly consistent with that strategy. We have demonstrated, through the paxalisib program, our ability to add value to a development candidate, and we intend to similarly accelerate EVT801 via a rich and innovative development program."

Evotec CEO, Dr Werner Lanthaler, commented, "we are very pleased to partner with Kazia for this promising asset, for which we have high hopes. Our corporate strategy does not provide for Evotec to take EVT801 through clinical trials itself, so we have sought to identify a partner who can do justice to the drug’s potential. We recognise Kazia’s track record and look forward to working together to make EVT801 available to patients and clinicians."

EVT801

EVT801 is a small molecule inhibitor of vascular endothelial growth factor receptor 3 (VEGFR3). It is orally available, and so can be administered to patients by mouth.

For more than two decades, one of the most successful approaches in the treatment of cancer has been to target angiogenesis, the formation of new blood vessels. Drugs which inhibit angiogenesis, such as Avastin (bevacizumab), starve the growing tumour of nutrients. However, inhibiting angiogenesis also results in hypoxia (low levels of oxygen) around the tumour, and this is thought to generate resistance to treatment. Almost all cancers treated with current anti-angiogenic drugs will eventually develop resistance.

An alternative approach, which may avoid this problem, is to target lymphangiogenesis, which is the formation of new lymphatic vessels. Doing so achieves many of the same objectives as targeting angiogenesis but may avoid the problem of resistance induced by hypoxia. Moreover, the lymphatic system is a common route by which tumours spread (metastasise) throughout the body, and so inhibiting lymphangiogenesis may help to limit the ability of the tumour to spread.

In recent years, several new drug candidates have attempted to inhibit lymphangiogenesis. For example, Nexavar (sorafenib) inhibits several forms of VEGFR, as well as other targets, and is approved for the treatment of renal cell carcinoma and hepatocellular carcinoma. Several drugs described as angiokinase inhibitors are in development, and some of these inhibit VEGFR3. However, each of these drugs has multiple targets, leading in many cases to significant side effects. The distinguishing feature of EVT801 is a high degree of specificity for VEGFR3, which should allow it to minimise toxicity.

In addition, EVT801 has shown powerful evidence in the laboratory of an ability to change the balance of immune cells within the tumour. Many tumours are resistant to the newest generation of immuno-oncology therapies because they do not contain the right immune cells for the drugs to act upon. It is hoped that administration of EVT801 may help to sensitise these tumours to immuno-oncology therapies such as Keytruda (pembrolizumab) and Opdivo (nivolumab) and thereby extend their use.

Kazia expects to explore all these potential uses of EVT801 during the clinical program. The initial focus will be on a phase I study, which is expected to be conducted at one or more leading hospitals in France and to commence in CY2021.

Master Services Agreement

In parallel with the license agreement, Kazia and Evotec have entered into a Master Services Agreement (MSA), under which they will collaborate on the further development of EVT801. Kazia intends to utilise Evotec’s substantial capabilities and expertise in research, clinical trial management, biomarker development, and manufacturing, to expedite the development of EVT801.

Oncolytic virus(OV) has been proven to inhibit tumor growth in a number of superficial tumors through intratumoral injection. From clinical studies, intratumoral injection of OV has been proved to provide effective treatment against tumor via its abscopal effect, transitions from immunologically cold to hot tumor and combination with other cancer therapies. However, to advanced tumors, especially the lesions of multiple metastasis are ideally treated via a systemic route. At present, common types of viruses that have been studied clinically for intravenous administration are Vaccinia virus, Coxsackie virus and Reovirus etc. However, for various reasons, most virus types used in developing oncolytic viruses including HSV-1 and adenoviruses, have not been fully studied for intravenous administration preclinically and clinically.

In the preclinical study conducted by ImmVira, intravenous administration of MVR-T3011 demonstrated enrichment of viral DNA in tumor tissue. MVR-T3855, the surrogate of MVR-T3011 for mouse, was shown to significantly extend the survival time of several mouse with orthotopic tumors including primary and metastatic lung cancer and primary liver cancer, and repeated dose via intravenous administration has clearly enhanced antitumor effect. Furthermore, intravenous administration or intra-cavity of MVR-T3855 significantly delayed or prevented the formation of malignant ascites in mouse liver model. In terms of safety, the three-month pre-clinical study showed that the intravenous administration of MVR-T3011 and MVR-T3855 did not cause significant adverse reactions and had clinical significance. After administration, no histopathological change was found in non-target organs.

ImmVira submitted an IND application for MVR-T3011 intravenous administration to the U.S. FDA in January 2021 and expects to recruit patients in five leading U.S. research cancer centers within the next few weeks.

On April 19, 2021 Epizyme reported that The protein EZH2 has long been known as a major driver of prostate cancer because of its ability to inactivate genes that would normally suppress tumor growth (Press release, Epizyme, APR 19, 2021, View Source [SID1234578328]). Now, a team at Cedars-Sinai Cancer has shown in preclinical models of the disease that blocking EZH2 reduces resistance to immune-boosting checkpoint inhibitors—and they did it with the help of Epizyme, which won FDA approval for the first EZH2 blocker last year.

The Cedars-Sinai team inhibited EZH2 in preclinical prostate cancer models, activating interferon-stimulated genes in the immune system. The interferons then boosted the immune response and reversed resistance to drugs that inhibit the checkpoint PD-1, they reported in the journal Nature Cancer.

By inhibiting EZH2 either genetically or with a chemical inhibitor donated by Epizyme, the researchers used a technique called "viral mimicry" to "reopen" parts of the genome that are typically inactive, they explained in a statement. That signaled the immune system to respond to PD-1 inhibition.

Cedars-Sinai is now planning a clinical trial of Epizyme’s EZH2 inhibitor, Tazverik (tazemetostat), in prostate cancer. The researchers believe combining checkpoint inhibitors with EZH2 blockers may be a viable strategy, they said.

RELATED: ESMO (Free ESMO Whitepaper): Early days, but Amgen’s BiTE drug in prostate cancer shows encouraging activity

Checkpoint inhibitors have been approved to treat several cancer types, but they’ve been largely disappointing in prostate cancer. Hence several research groups have been exploring combination strategies. They include the University of Texas MD Anderson Cancer Center, which published research in 2019 showing early evidence that combining checkpoint inhibition with anti-TGF-beta drug could be effective in prostate cancer.

More recently, bispecific antibodies have shown early promise in prostate cancer. Last September, Amgen presented data from a phase 1 study of AMG 160, a bispecific targeting PSMA and CD3 on T cells. The company said that 68.6% of patients experienced a decline in PSA, and eight out of 15 patients evaluated showed stable disease.

Regeneron is also developing a bispecific antibody for prostate cancer, targeting PSMA and CD28. The drug is being tested as a solo therapy and in combination with Regeneron’s PD-1 inhibitor Libtayo in a phase 1/2 clinical trial enrolling men with metastatic castration-resistant prostate cancer.

As for Epizyme’s EZH2 inhibitor, Tazverik, its path to market hasn’t been perfectly smooth. An advisory committee to the FDA questioned its efficacy and safety in its initial indication, metastatic or locally advanced epithelioid sarcoma. Still, the company got the go-ahead to market the drug in adult patients with the rare cancer last January. Then the FDA added follicular lymphoma to the label in June. The drug’s takeoff has been slower than expected, however, largely because the pandemic has prevented face-to-face interactions between the sales force and physicians.

The company is currently testing Tazverik in several other cancer types, including as a combination with standard-of-care treatments in castration-resistant prostate cancer.
