ImmunoPulse IL-12, which employs intratumoral electroporation to enhance delivery of DNA-based interleukin-12 (IL-12), is designed to promote an anti-tumor immune response.

"This study will address one of the great unmet medical needs in oncology today: the number of patients who do not respond to anti-PD-1 treatment," said Mai H. Le, MD, Chief Medical Officer of OncoSec. "As we expand the application of ImmunoPulse IL-12 beyond cutaneous cancer indications, we anticipate that it will augment the anti-tumor immune response in HNSCC and increase the number of patients who will respond to anti-PD-1 therapy."

Robert H. Pierce, MD, Chief Scientific Officer of Oncosec and a member of the anti-PD-1 Biomarker Team while at Merck, added, "Key biomarker data was recently presented at the 2015 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) annual meeting, showing that a specific NanoString-based gene expression profile characterizes anti-PD-1 response in HNSCC. Importantly, at OncoSec, we have observed the ability of ImmunoPulse IL-12 to promote this NanoString gene expression signature in melanoma, and we anticipate that this will be observed in HNSCC as well."

The lead investigators for OMS-I130 are Tanguy Seiwert, MD, from the University of Chicago and lead author of the presentation outlining the key gene signature for anti-PD-1 responders with HNSCC, and Alain Algazi, MD, from the University of California, San Francisco.

"Median overall survival in recurrent and metastatic HNSCC is less than one year even with aggressive, multi-agent chemotherapy. Immune checkpoint inhibitors, including anti-PD-1 antibodies, can achieve durable remissions in some patients, but these therapies are ineffective in the majority of patients because tumor-fighting immune cells and signals are missing from the tumor," said Dr. Algazi. "ImmunoPulse IL-12 allows tumors to produce key immune signals and attract these immune cells, which can potentially provide the missing link that will allow the majority of patients to achieve long-term remission."

OMS-I130 is a single-arm, open-label study evaluating the safety and anti-tumor activity of intratumoral DNA-based IL-12 with electroporation in approximately 30 patients with treatment-refractory metastatic and unresectable HNSCC. The key endpoints include: objective response evaluations by RECIST v1.1 and immune-related Response Criteria (irRC); biomarker comparisons of pre- and post-treatment tumor biopsies, including NanoString gene expression profiling and immunohistochemistry for tumor-infiltrating lymphocytes (TILs); duration of response to treatment; overall survival; progression-free survival; and safety.

About Squamous Cell Carcinoma of the Head and Neck
Squamous cell carcinoma (SCC) of the head and neck is one of most common causes of cancer-associated mortality worldwide. While the incidence of SCC of the head and neck (HNSCC) that is attributable to traditional risk factors, smoking and alcohol abuse, is declining, the incidence of SCC of the oropharynx due to HPV infection is on the rise.1

HNSCC can be treated with surgery, radiation, or chemoradiation in 60-90 percent of patients, but a substantial number of patients will develop recurrent or distant metastatic disease after locoregional therapy. These recurrences are associated with a poor overall prognosis2, and the median overall survival in patients with metastatic HNSCC is under a year even with intensive combination chemotherapy.3

The limited efficacy of standard of care treatment options means that 11,500 patients die every year from squamous cell carcinoma of the oral cavity and the oropharynx in the United States alone.1 There is a clear medical need in head and neck cancers for more effective treatment options to minimize toxicity and improve efficacy.

Taiho Pharmaceutical Co., Ltd. and Servier Enter Into License Agreement for Development and Commercialization of Oral Anticancer Drug TAS-102 in Europe

On June 15, 2015 Taiho Pharmaceutical Co., Ltd. (Japan) and Servier (France) reported on June 15 that they have entered into an exclusive license agreement on June 12, 2015 for the development and commercialization of TAS-102 (nonproprietary names: trifluridine and tipiracil hydrochloride) in Europe and other countries (Press release, Servier, JUN 15, 2015, View Source [SID1234529066]). Taiho Pharmaceutical Co., Ltd. retains the right to develop and commercialize TAS-102 in the United States, Canada, Mexico and Japan/Asia and to manufacture and supply the product. TAS-102 is an oral combination anticancer drug initially developed by Taiho Pharmaceutical Co., Ltd. for use in the treatment of refractory metastatic colorectal cancer (mCRC).

Under this agreement, Taiho Pharmaceutical Co., Ltd. will receive a total of US$ 130 million in an upfront payment and for MAA approval in the EU. In addition, Taiho will receive further regulatory and sales event milestone payments and royalties based on net sales. Taiho and Servier will also collaborate on the further global development of TAS-102 sharing effort and cost on an equal basis.

TAS-102 is currently under review by Health Authorities in Europe and the United States and in 2014 was approved for marketing in Japan. In the United States, Taiho Oncology Inc., a subsidiary of Taiho Pharmaceutical Co., Ltd., will market TAS-102.

"We are very pleased to enter into this agreement for TAS-102 with Servier who has a strong presence around the world especially in Europe as a research-based pharmaceutical company and has made a long term commitment to oncology," said Masayuki Kobayashi, President and Representative Director of Taiho Pharmaceutical Co., Ltd.

"This partnership with Taiho will hopefully allow us to rapidly bring a new therapeutic option to patients suffering from refractory metastatic colorectal cancer in Europe and other countries," said Olivier Laureau, President of Servier. "We respect and value Taiho’s well-known expertise in the development of oral cancer drugs and hence this collaboration will contribute to develop Servier’s capabilities in oncology. Such a landmark agreement confirms Servier’s strong ambition in oncology and our willingness to bring to cancer patients new therapeutic solutions through Servier’s extensive portfolio of innovative treatments currently in clinical development. This is in line with our commitment to therapeutic progress for the benefit of patients."

Taiho Pharmaceutical Co., Ltd. and Servier anticipate that TAS-102, as a new treatment option, will make an even greater contribution to cancer patients in Europe and other countries through their partnership.

About TAS-102

TAS-102 is an oral combination anticancer drug of trifluridine (FTD) and tipiracil hydrochloride (TPI). FTD is an antineoplastic nucleoside analog, which is incorporated directly into DNA, thereby interfering with the function of DNA. The blood concentration of FTD is maintained via TPI, which is an inhibitor of the FTD-degrading enzyme, thymidine phosphorylase. TAS-102 is commercially available in Japan and is under regulatory review in the United States of America and the European Union for the treatment of refractory metastatic colorectal cancer.

About Refractory Metastatic Colorectal Cancer

There are no definitive data on the number of patients who are refractory to standard metastatic colorectal cancer treatments; however, colorectal cancer is one of the most common cancers in the European Union (i) and the third most common cancer worldwide (ii). In 2013, a study published in the European Journal of Cancer revealed that an estimated 447,000 patients (242,000 men and 205,000 women) were diagnosed with and 215,000 patients died of colorectal cancer in Europe in 2012 (i). In addition, the American Cancer Society estimated that 136,830 patients (71,830 men and 65,000 women) were diagnosed with and 50,310 patients died of cancer of the colon and rectum in the United States in 2014 (iii).

Subgroup Analyses of a Phase 3 Study in Patients with Myelodysplastic Syndromes Failing HMA Treatment: Identification of a Homogeneous Population Who Benefit from Rigosertib Therapy

In-depth analysis of ONTIME, and found that patients with the worst prognosis at entry, and thus with the greatest unmet medical need, appeared to benefit most from rigosertib treatment; namely, those with Primary AZA Failure, Very High Risk (VHR)-Revised International Prognostic Scoring System (IPSS-R), and monosomy 7 (Poster, Onconova, JUN 15, 2015, View Source;fileid=835336&filekey=758FA9A5-D91E-46AA-BC88-6A3B6C7CC728&filename=Gaidano_EHA_2015_ONTIME_subgroups.pdf [SID:1234507264]). The analyzed duration of prior hypomethylating agent (HMA) treatment inversely correlated with survival benefit.
Based on these results, a new randomized prospective controlled study in this high-risk MDS patient population comparing rigosertib to physician’s choice will be conducted to confirm these important observations.

Actavis plc is now Allergan plc

8-K – Current report

On June 15, 2015 Karyopharm Therapeutics reported the presentation of positive clinical data for its lead product candidate, selinexor (KPT-330), a first-in-class, oral Selective Inhibitor of Nuclear Export / SINE compound, at the 20th Congress of the European Hematology Association (EHA) (Free EHA Whitepaper) 2015 Annual Meeting held June 11-14, 2015 in Vienna, Austria (Filing, 8-K, Karyopharm, JUN 15, 2015, View Source [SID:1234505437]).

In an ongoing Phase 1b company-sponsored clinical trial evaluating the activity of single-agent selinexor (doses of 3-80mg/m2) in heavily pre-treated patients with diffuse large B-cell lymphoma (DLBCL), selinexor demonstrated a 43% overall response rate (partial response or better) in patients on study greater than one month, and a 31% overall response rate across all doses in the intention to treat population, with a median duration of response (DOR) of greater than nine months. Similar responses were observed in both GCB and non-GCB subtypes. The median overall survival (OS) and progression free survival (PFS) were 4.6 months and 1.7 months, respectively, for the entire study. In patients with a response to selinexor (N=12), the median OS was greater than 10 months (median not reached) and PFS was 24 months, significantly longer than those without a response (N=27; OS 3.5 months, PFS 1.2 months). Adverse events were manageable with standard supportive care and clinically significant cumulative toxicities were not observed, with several patients remaining on selinexor for more than one year.

Additional clinical data on selinexor’s activity in DLBCL, including in patients with double-hit DLBCL, will be provided in an oral presentation on Saturday June 20, 2015, at 10:50 CEST by Dr. Ramiro Garzon from the Ohio State University at the 13th International Conference on Malignant Lymphoma (ICML) in Lugano, Switzerland.

Initial data from the ongoing Selinexor AraC Idarubicin Leukemia, or "SAIL," study, an investigator-sponsored Phase 2 clinical trial of selinexor with intensive chemotherapy (idarubicin and cytosine arabinoside [Ara-C]) in patients with acute myeloid leukemia (AML) that relapsed after standard intensive induction chemotherapy, were also reported. In 18 evaluable patients, the combination of selinexor (40 mg/m2) with idarubicin/Ara-C demonstrated a 56% overall response rate, including nine patients with complete remission (CR/CRi) and one patient with a partial remission. Adverse events were manageable with standard supportive care and dose adjustments.

"We are excited by these promising data presented at EHA (Free EHA Whitepaper), which continue to demonstrate the vast potential of selinexor across hematologic malignancies and provide further evidence of selinexor’s broad and durable activity, both as a single agent and in combination therapy," said Sharon Shacham, PhD, MBA, President and Chief Scientific Officer of Karyopharm. "The correlation between response and prolonged survival demonstrated in heavily pretreated DLBCL patients suggests that responses to selinexor may confer a clinical benefit in this very difficult to treat population and support the ongoing

SADAL study in this group of patients. Moreover, the preliminary clinical data in patients with relapsed/refractory AML suggest that selinexor can be combined effectively with manageable side effects. These findings represent the reported clinical data of selinexor in combination with intensive chemotherapy and suggest that selinexor can enhance the activity of these agents with manageable side effects."

Selinexor data in DLBCL were described during an oral presentation by Dr. Ramiro Garzon of the Ohio State University on Saturday, June 13, entitled "Patients with Heavily Pretreated Diffuse Large B-Cell Lymphoma (DLBCL) who Respond to Oral Selinexor Therapy Show Prolonged Survival: Updated Phase 1 Results." These data from an ongoing Phase 1b clinical study of single-agent selinexor (3-80 mg/m2 oral doses) in patients with DLBCL were as of June 1, 2015 and included the following highlights:

• Among 28 response evaluable patients (per protocol defined as those patients on study for at least one month), the ORR was 43% and the disease control rate (stable disease or better) was 71%. Responses included four patients (14%) who achieved a complete response as confirmed by PET scan, eight patients (29%) who achieved a partial response and 8 patients (29%) with stable disease.

• Among 39 patients treated across all doses, the ORR was 31% and the disease control rate (stable disease or better) was 51%.

• Duration of response was greater than nine months.

• Patients with a response to selinexor (N=12), achieved OS of greater than ten months (median not reached) and PFS of 24 months which were significantly longer than those without a response (N=27; OS 3.5 months, PFS 1.2 months).

• The median overall survival (OS) and progression free survival (PFS) were 4.6 months and 1.7 months, respectively, for the entire study.

• Selinexor showed similar activity in both GCB and non-GCB subtypes of DLBCL.
In a late-breaking poster presented on Saturday, June 13, entitled "Preliminary Phase II Results of Ara-C And Idarubicin in Combination with Selective Inhibitor of Nuclear Export (SINE) Compound Selinexor (KPT-330) in Patients with Relapsed or Refractory AML," Dr. Walter Fiedler of the University Medical Center Hamburg and colleagues described preliminary data from the ongoing Phase 2 SAIL clinical trial demonstrating that selinexor in combination with standard doses of Ara-C and idarubicin is a potentially effective strategy for treating patients with AML that was relapsed or refractory after at least one line of chemotherapy. All data are as of April 27, 2015 and highlights include:

• An overall response rate of 56% was achieved based on 18 evaluable patients with three patients (17%) achieving complete remission (CR), six patients (33%) achieving complete remission with incomplete blood count recovery (CRi) and one patient (6%) achieving partial remission (PR).

• Ten patients (56%) received or were expected to receive either stem cell transplant or donor lymphocyte infusion.

• Adverse events were manageable with standard supportive care and dose adjustments.
An additional poster was presented on Saturday, June 13, entitled "XPO1 Inhibition Using Selinexor Synergizes with Chemotherapy in Acute Myeloid Leukemia (AML) by Targeting DNA Repair Genes" by Dr. Romero Garzon of the Ohio State University. In that preclinical study, Dr. Garzon and colleagues showed that selinexor synergizes with anthracyclines and other topoisomerase 2 inhibitors by preventing AML cells from repairing their DNA after damage by the chemotherapy. This study provides the scientific rationale for the ongoing SAIL study described above and additional studies with topoisomerase 2 inhibitors, as well as mechanistic insights into the use of selinexor with other chemotherapeutic agents.

About Selinexor
Selinexor (KPT-330) is a first-in-class, oral Selective Inhibitor of Nuclear Export / SINE compound. Selinexor functions by binding with and inhibiting the nuclear export protein XPO1 (also called CRM1), leading to the accumulation of tumor suppressor proteins in the cell nucleus, which subsequently reinitiates and amplifies their tumor suppressor function. This is believed to lead to the selective induction of apoptosis in cancer cells, while largely sparing normal cells. Over 900 patients have been treated with selinexor in company- and investigator-sponsored Phase 1 and Phase 2 clinical trials in advanced hematologic malignancies and solid tumors. Karyopharm has initiated four registration-directed clinical trials of selinexor, including one in older patients with acute myeloid leukemia (SOPRA), one in patients with Richter’s transformation (SIRRT) and one in patients with diffuse large B-cell lymphoma (SADAL). A single-arm trial of selinexor in patients with multiple myeloma (STORM) that is also intended to be registration-directed was initiated in May 2015. In solid tumors, Karyopharm plans to initiate a registration-directed trial of selinexor to treat liposarcoma during the second half of 2015. Additional Phase 1 and Phase 2 studies are ongoing or currently planned, including multiple studies in combination with one or more approved therapies in a variety of tumor types to further inform the company’s clinical development priorities for selinexor. The latest clinical trial information for selinexor is available at www.clinicaltrials.gov.
