This open-label trial funded by MedImmune, the global biologics research and development arm of AstraZeneca, is sponsored by noted cancer researcher Dr. Michael Frumovitz, MD, MPH, of the MD Anderson Cancer Center in Houston, Texas. MedImmune is evaluating MEDI0457 in combination with durvalumab, an anti-PD-L1 immune checkpoint inhibitor, in patients with HPV-associated cervical, anal, penile, and vulvar cancers in arms of a clinical trial with an estimated total enrollment of 77 patients. For additional information about the study, please visit www.clinicaltrials.gov (search identifier NCT03439085).

The opening of this trial will result in a milestone payment from MedImmune to Inovio. Financial arrangements were not disclosed.

Dr. Frumovitz said, "This is the first Phase 2 clinical trial at MD Anderson that is focused not on the site of disease origin, but instead on the cause of a cancer — in this case exposure to HPV 16 or 18. The HPV Moon Shot at MD Anderson has developed an entire research program with this philosophy in mind — that HPV-associated cancers behave similarly, regardless of site of origin, and should be studied as a whole, not as individual cancers. This study will be "site agnostic", meaning any patient with an HPV 16/18 associated cancer, regardless of primary site, will be eligible. Another truly unique aspect of this study is a separate cohort for patients who are HIV positive with an HPV 16/18 associated cancer."

Dr. J. Joseph Kim, Inovio’s President and Chief Executive Officer, said, "We are pleased to see Inovio’s cancer-fighting immunotherapy, in MEDI0457, expand to new cancer indications. Such expansion is great for patients and the oncology community. For Inovio, amplification of HPV cancer targets holds the potential to bring about additional milestone and royalty payments."

An article in the online edition of Clinical Cancer Research highlights a recent Phase 1 study of MEDI0457 as a monotherapy in 22 HPV-positive patients with HPV-associated head and neck cancer that demonstrated MEDI0457 generated robust HPV16/18 specific CD8+ T cell responses in peripheral blood and increased CD8+ T cell infiltration in resected tumor tissue. One patient in that trial who initially displayed a slight increase in T cell immune responses developed progressive disease at 11 months into the study and subsequently received a PD-1 checkpoint inhibitor. The patient achieved a complete response, which has sustained for over two years and counting. Increasing evidence suggests that response rates from checkpoint inhibitors can be enhanced when used in combination with cancer vaccines like MEDI0457 that generate tumor-specific T cells.

About MEDI0457 and VGX-3100

MEDI0457 (formerly called INO-3112 (VGX-3100, plus IL-12) which MedImmune in-licensed from Inovio) is under evaluation by MedImmune to treat HPV-associated cancers. Inovio is investigating VGX-3100, a DNA-based immunotherapy for the treatment of HPV-16 and HPV-18 infection and pre-cancerous lesions of the cervix (Phase 3) and vulva (Phase 2) and anal (Phase 2). VGX-3100 has the potential to be the first approved treatment for HPV infection of the cervix and the first non-surgical treatment for pre-cancerous cervical lesions. VGX-3100 works by stimulating a specific immune response to HPV-16 and HPV-18, which targets the infection and causes destruction of pre-cancerous cells. In a randomized, double-blind, placebo-controlled Phase 2b study in 167 adult women with histologically documented HPV-16/18 cervical HSIL (CIN2/3), treatment with VGX-3100 resulted in a statistically significantly greater decrease in cervical HSIL and clearance of HPV infection vs. placebo. The most common side effect was injection site pain, and no serious adverse events were reported. VGX-3100 utilizes the patient’s own immune system to clear HPV-16 and HPV-18 infection and pre-cancerous lesions without the increased risks associated with surgery, such as loss of reproductive health and negative psychosocial impacts.

Under the 2015 agreement, MedImmune acquired exclusive rights to Inovio’s INO-3112, now called MEDI0457. MEDI0457 targets cancers caused by HPV types 16 and 18 which are responsible for more than 70 percent of cervical pre-cancers and cancers and are involved in the development of other tumors. Within the broader license and collaboration agreement, MedImmune and Inovio are co-developing one additional DNA-based cancer therapy product not included in Inovio’s current product pipeline, which MedImmune has exclusive rights to develop and commercialize. Inovio will receive development, regulatory and commercialization milestone payments for these additional cancer vaccine products and will be eligible to receive royalties on worldwide net sales.

About Durvalumab

Durvalumab, a human monoclonal antibody directed against PD-L1, blocks PD-L1 interaction with PD-1 and CD80 on T cells, countering the tumor’s immune-evading tactics and inducing an immune response. As part of a broad development program, durvalumab is being investigated as monotherapy and in combination with IO, small molecules, and chemotherapies across a range of tumors and stages of disease.

On December 4, 2018 AUM Biosciences (AUM), a Singapore headquartered oncology-focused biotechnology company, reported that it has licensed its first novel, highly selective anti-cancer drug, ETC-206, from A*STAR’s Experimental Therapeutics Centre (ETC) (Press release, AUM BioSciences, DEC 4, 2018, View Source [SID1234533612]). The Agency for Science, Technology and Research (A*STAR) is Singapore’s lead public sector agency that spearheads economic oriented research to advance scientific discovery and develop innovative technology.

AUM has licensed the global rights to develop, commercialize and manufacture ETC-206 in all indications. ETC-206 was discovered and developed through a collaboration between A*STAR’s Experimental Therapeutics Centre (ETC) and Duke-NUS Medical School (a partnership between Duke University School of Medicine and the National University of Singapore). It advanced into first-in-man trials in December 2016. Initial clinical studies suggest that ETC-206 is very well tolerated and could be used as a thera∂ßpy across a range of liquid and solid tumor types.

The drug promises a more targeted approach by inhibiting the Mnk enzyme in cancer cells, which is a key player in promoting cancer growth when activated. This could lower mortality rates for cancer and improve quality of life for cancer patients compared to traditional chemotherapy, which kills cells in a less specific fashion and affects more than just the cancer cells.

"Due to low efficacy and steep costs associated with many cancer treatments, the demand for more precise anti-cancer treatments has become imperative. AUM’s small molecule and biomarker driven approach allows us to implement innovative trial designs enabling "multiple shots on goal", in cancer treatment," AUM’s Chief Executive Officer, Mr. Vishal Doshi said.

ETC-206 is the first in AUM’s pipeline of novel targeted therapies with the potential to be developed both independently and in combination with other therapies. The drug’s ability to isolate and target only cancerous cells promises a breakthrough opportunity globally.

"ETC-206 is a prime example of how A*STAR has been able to translate R&D into positive outcomes to create economic growth and enhance lives for Singaporeans. We look forward to working closely with more Singapore based enterprises such as AUM Biosciences as we continue to leverage our drug discovery and development capabilities to support the growth of the local biotech ecosystem in Singapore." Said Dr Damian O’Connell, Chief Executive Officer of A*STAR’s Experimental Therapeutics Centre.

"Duke-NUS scientists and researchers have led many discoveries with great potential for the welfare of people in Singapore and beyond," stated Dr. David Epstein, Director of Duke-NUS’ Centre for Technology and Development (CTeD), and the School’s Vice Dean for Innovation and Entrepreneurship, who is also an associate professor of the Cancer and Stem Cell Biology Programme. "ETC-206 is an important accomplishment exemplifying Duke-NUS’s mission of facilitating the translation of basic research into commercial entities and products. We are proud to partner with A*STAR in realizing this enterprising venture that was ‘Made in Singapore’ and is being taken forward by AUM, a Singapore-based startup. We look forward to more startups creating entrepreneurship opportunities in the sector."

ETC-206’s licensing by AUM not only puts Singapore on the map, but also enables the company to be at the forefront of emerging oncology trends. This is a significant step towards its vision of "Asia to global" by accelerating the development of innovative and affordable medicines.

"We are now speaking with investors to accelerate ETC-206’s development and our broader molecule acquisition roadmap. AUM will fund further clinical development and will be responsible for regulatory filings, and for clinical studies for this and future drugs," Mr. Doshi commented.

As a future roadmap, AUM has a strategic focus of acquiring and developing promising small molecules targeted oncology assets to unlock their potential, including those that are de-prioritized or not progressed by their originators due to strategic and financial limitations in the healthcare industry. Its mandate of "No biomarker, No drug" serves to increase the probability of success.

Cancer prevalence in Asia is estimated at 17.4 million in 2018, with about 8.8 million new cases every year, accounting for about half of the new global cancer cases. The number of new cases in Asia is expected to increase from 8.8 million in 2018 to 11.8 million by 2030 creating a huge unmet medical need in Asia.

On December 4, 2018 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported new data from the Venclexta/Venclyxto (venetoclax) clinical development programme, including longer-term results from the phase III MURANO study in people with previously treated chronic lymphocytic leukaemia (CLL) and updated data from two phase Ib/II studies in people with previously untreated acute myeloid leukaemia (AML) ineligible for intensive chemotherapy due to coexisting medical conditions (Press release, Hoffmann-La Roche, DEC 4, 2018, View Source [SID1234531851]). Data from the Venclexta/Venclyxto clinical development programme that ranges across multiple blood cancers, including CLL, AML, non-Hodgkin lymphoma and multiple myeloma, will be featured in more than 30 abstracts, including 12 oral presentations, at the 60th American Society of Hematology (ASH) (Free ASH Whitepaper) 2018 Annual Meeting.

"We’re excited by the versatility of Venclexta/Venclyxto in treating a range of distinct types of blood cancer, including difficult-to-treat forms with limited options," said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. "These data support our broad clinical development programme through which we hope to discover more ways Venclexta/Venclyxto can be used alone or in combination with other medicines to treat additional types of cancer."

Updated data in CLL
Two new analyses of the phase III MURANO study in relapsed or refractory (R/R) CLL demonstrated the continued clinical benefit of Venclexta/Venclyxto plus MabThera/Rituxan (rituximab) was sustained after patients completed the chemotherapy-free, two-year fixed-duration course of therapy.

An analysis showed the combination reduced the risk of disease progression or death (progression-free survival; PFS, as assessed by investigator) by 84% (HR=0.16; 95% CI: 0.12-0.23; p<0.0001) compared to standard of care bendamustine plus MabThera/Rituxan (BR) after a median three-year follow-up. At three years, 71% of patients in the Venclexta/Venclyxto plus MabThera/Rituxan arm had not experienced disease progression, compared to 15% of patients in the BR arm (median PFS: not reached vs. 17.0 months, respectively). A clinically meaningful benefit in overall survival was also observed in the Venclexta/Venclyxto arm compared to the BR arm (88% vs. 80%, HR=0.50; 95 percent CI: 0.30-0.85). Consistent benefit was observed in all patient subgroups for Venclexta/Venclyxto plus MabThera/Rituxan compared to BR, including high-risk and low-risk groups. Data were presented in an oral session on Saturday, 1 December at 14:45 PST (Abstract #184).
A separate analysis showed higher rates of minimal residual disease (MRD)-negativity observed with Venclexta/Venclyxto plus MabThera/Rituxan compared to BR were sustained after patients completed treatment (62% vs. 13%). MRD-negativity means no cancer can be detected using a specific, highly sensitive test, and was defined as less than 1 CLL cell in 10,000 leukocytes. Importantly, these results were observed in the majority of patients in the Venclexta/Venclyxto arm, including patients in high-risk subgroups and were consistent with the maintained PFS benefit seen with longer follow-up. These data support the utility of MRD in peripheral blood as a predictive marker of clinical outcome. No new safety signals were observed with the treatment combination of Venclexta/Venclyxto plus MabThera/Rituxan. These data will be presented in an oral session on Monday, 3 December at 11:30 PST (Abstract #695).
Updated data in AML
Updated data from the phase Ib M14-358 and phase I/II M14-387 studies evaluating Venclexta/Venclyxto in combination with a hypomethylating agent or low-dose cytarabine (LDAC) in people with previously untreated AML who are ineligible for intensive chemotherapy, will also be presented. These results showed that among patients who were dependent upon blood transfusions at baseline, about half were able to achieve transfusion independence (the absence of transfusions during any consecutive 56 days during the study treatment period). No unexpected safety signals were observed with Venclexta/Venclxyto in combination with hypomethylating agents or LDAC.

The M14-358 study showed high rates of complete remission (with at least partial blood count recovery, CR+CRh) of 67% for those who received Venclexta/Venclyxto plus azacitidine and 71% for those who received Venclexta/Venclyxto plus decitabine. For people taking Venclexta/Venclyxto and azacitadine or decitabine who were dependent on blood transfusions at baseline, 50% and 52% achieved red blood cell transfusion independence, respectively; and 58% or 60% achieved platelet transfusion independence, respectively.
The M14-387 study showed rates of complete remission (with or without full recovery of normal blood cell count, CR+CRi) of 54% in people who received Venclexta/Venclyxto in combination with LDAC and a median duration of remission of 8.1 months. For people taking Venclexta/Venclyxto with LDAC, 48% achieved red blood cell transfusion independence and 60% achieved platelet transfusion independence.
Results from the two studies were presented in an oral session on Sunday, December 2 at 7:45 PST and 8:00 PST, respectively (Abstract #284 and #285).

Based on earlier results from the M14-358 and M14-387 studies, Venclexta was granted accelerated approval by the US Food and Drug Administration (FDA) for the treatment of people with newly-diagnosed AML who are age 75 years or older, or for those ineligible for intensive induction chemotherapy due to coexisting medical conditions. A robust clinical development programme for Venclexta/Venclyxto in AML is ongoing, including two ongoing phase III studies evaluating Venclexta/Venclyxto in combination with azacitidine or with LDAC for people with previously untreated AML who are ineligible for intensive chemotherapy based on results from the M14-358 and M14-387 studies.

Venclexta/Venclyxto is being developed by AbbVie and Roche. It is jointly commercialised by AbbVie and Genentech, a member of the Roche Group, in the United States, and commercialised by AbbVie outside of the United States.

About the MURANO study
MURANO (NCT02005471) is a phase III open-label, international, multicentre, randomised study evaluating the efficacy and safety of Venclexta/Venclyxto in combination with MabThera/Rituxan compared to bendamustine in combination with MabThera/Rituxan (BR) in patients with relapsed or refractory chronic lymphocytic leukaemia (CLL). All treatments were of fixed duration. Following a five-week dose ramp-up schedule for Venclexta/Venclyxto, patients on the Venclexta/Venclyxto plus MabThera/Rituxan arm received six cycles of Venclexta/Venclyxto plus MabThera/Rituxan followed by Venclexta/Venclyxto monotherapy for up to two years total. Patients on the BR arm received six cycles of BR. The study included 389 patients with CLL who had been previously treated with at least one line of therapy. Patients were randomly assigned in a 1:1 ratio to receive either Venclexta/Venclyxto plus MabThera/Rituxan or BR. The primary endpoint of the study was progression-free survival (PFS). Secondary endpoints included overall survival, overall response rate and complete response rate (with or without complete blood count recovery).

About the M14-358 study
The M14-358 study (NCT02203773) is an open-label, non-randomised, phase Ib dose escalation and expansion study evaluating the safety and efficacy of Venclexta/Venclyxto in combination with hypomethylating agents, azacitidine or decitabine, in 115 newly-diagnosed people with acute myeloid leukaemia who were 60 years or older, or ineligible to receive intensive induction chemotherapy due to coexisting medical conditions. Study endpoints included complete remission rates, transfusion independence, overall survival and safety.

About the M14-387 study
The M14-387 study (NCT02287233) is an open-label, single-arm, phase I/II dose escalation and expansion study evaluating the safety and efficacy of Venclexta/Venclyxto in combination with low-dose cytarabine (LDAC) in 82 newly-diagnosed people with acute myeloid leukaemia who were 60 years or older, or ineligible to receive intensive induction chemotherapy due to coexisting medical conditions. Study endpoints included complete remission rates, transfusion independence, overall survival and safety.

About Venclexta/Venclyxto
Venclexta/Venclyxto is a first-in-class targeted medicine designed to selectively bind and inhibit the B-cell lymphoma-2 (BCL-2) protein. In some blood cancers and other tumours, BCL-2 builds up and prevents cancer cells from dying or self-destructing, a process called apoptosis. Venclexta/Venclyxto blocks the BCL-2 protein and works to restore the process of apoptosis.

Venclexta/Venclyxto is being developed by AbbVie and Roche. It is jointly commercialised by AbbVie and Genentech, a member of the Roche Group, in the United States, and commercialised by AbbVie outside of the United States. Together, the companies are committed to research with Venclexta/Venclyxto, which is currently being studied in clinical trials across several types of blood and other cancers.

In the US, Venclexta has been granted four Breakthrough Therapy Designations by the FDA: in combination with Rituxan for people with relapsed or refractory chronic lymphocytic leukaemia (CLL); as a monotherapy for people with relapsed or refractory CLL with 17p deletion; in combination with hypomethylating agents (azacitidine or decitabine) for people with untreated acute myeloid leukaemia (AML) ineligible for intensive chemotherapy; and in combination with low-dose cytarabine for people with untreated AML ineligible for intensive chemotherapy.

About Chronic Lymphocytic Leukaemia
Chronic lymphocytic leukaemia (CLL) is the most common type of leukaemia in the Western world.[1] CLL mainly affects men and the median age at diagnosis is about 70 years.[2] Worldwide, the incidence of all leukaemias is estimated to be more than 400,000[3] and CLL is estimated to affect around one-third of all people newly diagnosed with leukaemia.[1]

About Acute Myeloid Leukaemia
Acute myeloid leukaemia (AML) is an aggressive form of leukaemia that starts in immature forms of blood-forming cells, known as myeloid cells, found in the bone marrow.[4] AML is the most common type of aggressive leukaemia in adults. It has the lowest survival rates of all types of leukaemia.[5] Even with the best available therapies, older patients aged 65 and over have survival rates comparable to patients with advanced lung cancer, with a five year overall survival rate of <5%.[6;7] Approximately 20,000 people in the US and 18,000 in Europe are diagnosed with AML each year.[8;9]

On December 4, 2018 Verastem, Inc. (Nasdaq:VSTM) (Verastem Oncology or the Company), focused on developing and commercializing medicines to improve the survival and quality of life of cancer patients, reported the presentation of seven posters highlighting new and updated clinical and preclinical data from its duvelisib development program at the American Society of Hematology (ASH) (Free ASH Whitepaper) 2018 Annual Meeting, taking place December 1-4, 2018, in San Diego (Press release, Verastem, DEC 4, 2018, View Source;p=RssLanding&cat=news&id=2379420 [SID1234531868]). Duvelisib is an oral inhibitor of phosphoinositide 3-kinase (PI3K), and the first approved dual inhibitor of PI3K-delta and PI3K-gamma.

"The PI3K pathway is critical for the survival and proliferation of many types of cancer cells," said Robert Forrester, Verastem President and Chief Executive Officer. "At Verastem Oncology we are committed to progressing the scientific research and clinical development with our corporate, clinical and academic research partners worldwide to unlock the potential of PI3K inhibition and usher in new treatment strategies for patients in need."

"Research being presented at ASH (Free ASH Whitepaper) this year by Chen, et al used CLL patient samples to demonstrate critical points about dual PI3K-delta and PI3K-gamma inhibition," said Jonathan Pachter, PhD, Chief Scientific Officer at Verastem Oncology. "This research suggests that while PI3K-delta inhibition targets the malignant B cells directly, PI3K-gamma inhibition blocks the support of CLL growth by macrophages and T cells in the tumor microenvironment. Data presented show that when CLL cells from patients who progressed on ibrutinib were implanted in mice, dual PI3K-delta and PI3K-gamma inhibition effectively reduced the CLL burden thereby suggesting the potential value of the dual inhibition in tumors resistant to BTK inhibition. The importance of dual inhibition of PI3K-delta and PI3K-gamma, in this case in combination with BCL-2 inhibition, was also described by Ye, et al in an aggressive lymphoma model. This study highlights the synergistic activity of the combination in inhibiting ibrutinib resistance compensatory pathways and inducing apoptosis in preclinical models of Mantle Cell Lymphoma."

"We are delighted to have presented a wide range of data from our ongoing duvelisib development programs, including updated long-term follow-up data from the Phase 3 DUO study as well as the DUO crossover extension study," said Hagop Youssoufian, MSc, MD, Head of Medical Strategy at Verastem Oncology. "Other key presentations include the Zinzani and Lehmberg data, which describe compelling new biomarker research being conducted relating to predictive factors for response to duvelisib in certain hematologic malignancies."

On December 4, 2018 Clovis Oncology, Inc. (NASDAQ:CLVS) reported after opposition proceedings at The Hague, Netherlands, that the European Patent Office upheld claims of European Patent 2534153 in amended form covering certain crystalline forms of rucaparib camsylate, including rucaparib S-camsylate Form A, the crystalline form in Rubraca (Press release, Clovis Oncology, DEC 4, 2018, View Source [SID1234531884]).

In its oral decision announced at the hearing, the Opposition Division upheld claims, narrowed from the originally granted patent, to certain crystalline forms of rucaparib camsylate. These forms include, but are not limited to, the commercial product. The European Opposition Division found patentability of the claimed forms based on the inventiveness of these crystalline forms and a constellation of unexpected properties. The European patent was opposed by two opponents. Clovis and/or either opponent have an opportunity to appeal the decision of the European Opposition Division within two months of the written decision, which is expected in the next few months. If appealed, all claims in the originally granted patent will remain in force until the Technical Board of Appeal issues its decision.

In addition to the rucaparib camsylate patent protection through at least 2031 confirmed today, the commercial form of Rubraca is also entitled to European regulatory exclusivity until at least 2028 (and 2029 if an indication in a second tumor type is approved). Also, Clovis has filed for supplementary protection certificate (SPC) extension on this rucaparib camsylate patent in various European countries, which if approved, would provide extension of protection until 2033 under this patent.

"We are very pleased with the outcome of the opposition proceedings today, but more importantly, we are gratified that the European Patent Office acknowledged the innovation behind this invention and upheld robust patent protection for Rubraca in Europe," said Patrick J. Mahaffy, President and CEO of Clovis Oncology. "This patent represents an important component of the intellectual property for Rubraca and we are happy that the Opposition Division upheld the relevant claims of the patent that cover the commercial form of Rubraca as well as other forms of rucaparib camsylate. We look forward to commercializing Rubraca in Europe and with this outcome, we are well-positioned to do so for a very long time."

About Rubraca (rucaparib)

Rubraca is an oral, small molecule inhibitor of PARP1, PARP2 and PARP3 being developed in multiple tumor types, including ovarian, metastatic castration-resistant prostate, and bladder cancers, as monotherapy, and in combination with other anti-cancer agents. Exploratory studies in other tumor types are also underway. Clovis holds worldwide rights for Rubraca. Rubraca is an unlicensed medical product outside of the U.S. and Europe.
