"We are disappointed that the results did not demonstrate a significant improvement in overall survival and reduction in CMV end-organ disease," said Bernhardt G. Zeiher, president of Development, Astellas. "We would like to thank the patients and clinicians who participated in this important trial."

The Phase 3 trial was designed to evaluate the efficacy of ASP0113 compared with placebo in CMV-seropositive recipients undergoing an allogeneic stem cell transplant. Efficacy was assessed using a primary composite endpoint of overall mortality and CMV end-organ disease through the first year following the transplant, an endpoint which was not met. Secondary endpoints of time to first protocol-defined CMV viremia and time to first use of adjudicated CMV-specific antiviral therapy also were not met.

"The Phase 3 trial outcome is disappointing," said Vijay Samant, Vical’s Chief Executive Officer. "Astellas and Vical employees, the investigators and study site personnel did an outstanding job conducting this study, but unfortunately, the vaccine was unable to provide protection against all-cause mortality in this very difficult-to-treat patient population."

The Phase 3 trial was a 1:1 randomized, double-blind, placebo-controlled study that enrolled a total of 514 CMV seropositive subjects undergoing hematopoietic stem cell transplantation. Randomization was stratified by donor-recipient relatedness and donor CMV serostatus. Subjects were followed for one year post-transplant.

About Cytomegalovirus
CMV is a herpes virus that is estimated to infect more than half of all adults in the United States by age 50, and is even more widespread in developing countries. A healthy immune system typically protects an infected person against CMV disease, but does not prevent or clear latent infection. Individuals whose immune systems are not fully functional are at high risk of CMV reactivation, potentially leading to severe illness or death. Those at greatest risk include HCT and solid-organ transplant recipients, as well as infants born to mothers who first become infected during pregnancy.

About ASP0113
ASP0113 is an investigational vaccine candidate designed to prevent CMV disease and associated complications in CMV-seropositive HCT recipients. ASP0113 is a bivalent DNA vaccine encoding CMV phosphoprotein 65 and glycoprotein B antigens for induction of both cellular and humoral immune responses, formulated with a proprietary poloxamer-based delivery system. ASP0113 was initially developed by Vical which partnered with Astellas for further development and commercialization. ASP0113 received Orphan Drug Designation in the United States and Europe.

On January 22, 2018 Redx Pharma Plc (LON:REDX) reported that it has appointed a chief medical officer ahead of the imminent launch of phase I clinical trials of its lead drug (Press release, Redx Pharma, JAN 22, 2018, View Source [SID1234524742]).

Dr Andrew Saunders has 25 years in the cancer field and was recruited from Lytix Biopharma, a Norwegian immuno-oncology firm, where he held the same role.

He will work with the research and development team at Redx, "fronting" the clinical development of RXC004.

This is a potentially potent small molecule drug called a porcupine inhibitor that targets Wnt pathway.

Chairman Iain Ross said he was "very pleased" to announce Saunders’ appointment.

"He brings to the company a wealth of relevant experience and expertise in the clinical development of oncology drugs," Ross explained.

"This will be invaluable as the company transforms into a clinical stage company with the anticipated commencement of the first phase I study on lead compound RXC004 in the coming weeks.

"We are very excited by the potential of RXC004 to make a major difference in cancer treatment.

"We intend to progress RXC004 in the clinic both as a monotherapy and in combination with a checkpoint inhibitor. Therefore, we envisage that Andrew’s recent experience in immuno-oncology combination trials will be particularly pertinent to the design and execution of future clinical trials with RXC004."

Porcupine inhibitors such as RXC004 are a new and potentially breakthrough method of fighting the killer disease.

They work by targeting cancer stems cells that can often lie dormant after traditional treatment and are associated with a recurrence of the illness. Kill the stem cells and you have a chance of eradicating the disease completely.

Clinical trials of the new Redx drug commence in the "coming weeks".

On January 22, 2018 The biopharmaceutical company MOLOGEN AG (ISIN DE0006637200; Frankfurt Stock Exchange Prime Standard: MGN) reported data on its lead compound, the TLR9 agonist and immune surveillance reactivator lefitolimod, at the Annual 2018 Gastrointestinal Cancers Symposium (ASCO GI) in San Francisco (18 – 20 January 2018) (Press release, Mologen, JAN 22, 2018, View Source [SID1234523467]).

Monotherapy with lefitolimod resulted in a beneficial modulation of the tumor microenvironment (TME) associated with a reduced tumor growth in a murine model of colorectal cancer. The beneficial lefitolimod-induced modulation of the TME strongly supports its potential as cancer immunotherapeutic agent. Hence, in addition to its potential in monotherapy, lefitolimod may also be an ideal partner for immuno-oncology combination approaches, i.e. with checkpoint inhibitors.

"Beneficial modulation of the TME, in other words making immunologically "cold" tumors "hot", is a crucial requirement for the response to immunotherapeutic approaches. The presented data clearly support the mode-of-action of lefitolimod in our late-stage IMPALA study with single-agent lefitolimod in colorectal cancer. In addition they provide an excellent rationale for combining lefitolimod with checkpoint inhibitors. We know that checkpoint inhibitors need help to fully unfold their enormous potential and we believe that our TLR9 agonist lefitolimod will play a major role also in this context", said Dr Matthias Baumann, CMO of MOLOGEN AG.

Beneficial lefitolimod-induced modulation of the TME

After intratumoral injection of lefitolimod an increased infiltration of T cells (CD3+ T cells, especially CD8+ T cells) into the tumor was observed. Furthermore, also an increase of activated CD8+ T cells with cytolytic ("cell destruction capability") potential was determined. In addition, the injection of lefitolimod had a positive impact regarding so-called tumor-associated macrophages – immune cells that interact with tumor cells to influence the initiation, growth and metastasis of tumors. Lefitolimod led to an increase of anti-tumor M1-type macrophages within the tumor, accompanied with a decrease of pro-tumorigenic M2-type macrophages.
Importantly, this beneficial TME modulation from an immunosuppressed ("cold") towards a more immunoreactive ("hot") stage translated into a reduction of tumor growth in the mice.

Lefitolimod as a partner for immuno-oncological combination therapies

The lefitolimod-induced pathway provides the rationale for combining lefitolimod with checkpoint inhibitors. Response rates to checkpoint inhibitor immunotherapy vary between different tumor entities and depend on the nature of the TME. "Hot" tumors with a T cell infiltrated TME show better responses. Therefore modulation of the TME is a crucial requirement for the response to immunotherapeutic approaches.
First combination data of lefitolimod with checkpoint inhibitors have been presented at the ASCO (Free ASCO Whitepaper) GI 2017. The data showed that lefitolimod can significantly improve the anti-tumor effect of checkpoint inhibitors, particularly anti-PD-1 and anti-PD-L1 antibodies, and thus prolong survival in murine tumor models.

The new partnership’s efforts will take place pursuant to recent reforms by the China Food and Drug Administration office (CFDA), which include initiatives designed to accelerate drug approvals and encourage innovation, including greater alignment of China’s review process with that of the US and the EU.

"We are delighted to be collaborating with Jixi Biotechnology, which has resources and networks in regulatory affairs and commercialization in this critically important territory," says TLC President George Yeh. "This is an important step forward in our support toward China’s ongoing healthcare reforms and is a milestone in our efforts to address the needs of patients worldwide."

Under the terms of the agreements, TLC is entitled to receive US$20 million from Jixi Biotechnology in exchange for a minority stake in TLCHK and TLC will initially retain a majority stake in TLCHK. TLC will grant an exclusive right to TLCHK in the clinical trials, registration and commercialization of TLC’s products and product candidates in China. Upon the achievement of certain milestones prior to obtaining drug approval, Jixi Biotechnology will have the option to acquire additional stakes in exchange for aggregate payments of an additional US$50 million to TLC. Moreover, if TLCHK further fulfills certain corporate events, TLC would also be entitled to an additional payment up to US$60 million.

TLC’s pipeline focuses on the pain management, ophthalmology, and oncology spaces. The leading product candidate, TLC599, is a sustained release dexamethasone injection which has the potential to alleviate pain suffered by some of the estimated 42 million people with knee osteoarthritis in China. TLC399 is a sustained release dexamethasone injection which aims to treat macular edema due to retinal vein occlusion, a disease estimated to affect around 7.4 million patients in China. TLC590 is a sustained release post-surgical analgesic which has the potential to manage pain following surgical operations, of which there are nearly 40 million in China per year. TLC178 is a liposomal formulation of the anticancer drug vinorelbine which has received a Rare Pediatric Disease Designation from the FDA for rhabdomyosarcoma, which will qualify TLC178 in this indication for priority review in the US and may result in the granting of a transferable Priority Review Voucher that can reduce the standard ten-month FDA review time to six months. TLC has two approved products in oncology which are branded generics or off-patent drugs, a fast-growing sector in China.
