Kitov also today released a Letter from Chief Executive Officer, Isaac Israel, regarding recent activities and plans:

"Dear Shareholders,

Following the publication of our Annual Report for 2017, I would like to share with you our major accomplishments during 2017 and our plans and expectations for 2018.

HIGHLIGHTS OF 2017:

Consensi

Our team made important progress on our lead drug candidate, Consensi (which we formerly referred to as KIT-302).

Consensi, a combination drug that simultaneously treats pain caused by osteoarthritis and treats hypertension, is comprised of two FDA approved drugs, celecoxib (Celebrex), an NSAID, for the treatment of pain caused by osteoarthritis, and amlodipine besylate (Norvasc), a drug designed to treat hypertension. Hypertension is one of the side effects of using non-steroidal anti-inflammatory drugs, or NSAIDs, including celecoxib. Approximately 50% of the patients suffering from osteoarthritis in the US also suffer from hypertension, so industry sources estimate there are millions of patients that suffer from both conditions.

We made advances in several important areas:

Regulatory: The FDA filed our New Drug Application (NDA) for Consensi, following our submission of the NDA. We are very proud of the high-quality NDA package that was filed by the FDA. The FDA has set a PDUFA date of May 31, 2018 for Consensi.

Positive Clinical Trial Results: We announced the top-line results of our Phase III/IV randomized double-blind, placebo-controlled renal function clinical trial for Consensi. These results successfully validated the primary efficacy endpoint of our earlier successfully completed Phase III clinical trial. As such, we now have additional clinical evidence that establishes that adding celecoxib to amlodipine does not impair the blood pressure lowering effects of amlodipine. The trial also increased the total number of patients treated with Consensi, which we believe could increase the probability of ultimately receiving marketing approval for Consensi from the FDA.

Moreover, the Phase III/IV study strengthened the clinical evidence of the positive effect of Consensi on kidney function, which could provide us with a significant marketing advantage in the future.

Most importantly, we have advanced towards our goal of providing a safer NSAID, with the potential to be the first and only NSAID in the market which is both effective in lowering blood pressure and reduces the risk of kidney damage.

Commercial Partnership: We signed a definitive License Agreement for Consensi with Kuhnil Pharmaceutical Co. Ltd., a leading South Korean pharmaceutical company, for the territory of South Korea. Kuhnil will bear responsibility for and the costs of seeking regulatory approval for Consensi in South Korea. Under the terms of the agreement, we are entitled to receive payments upon achievement of certain predefined regulatory milestones, as well as double-digit royalties on net sales. Our relationship with Kuhnil and preparations for commercial launch in South Korea are proceeding as planned, and we have received our first milestone payment from Kuhnil.

South Korea is an important, attractive, gateway market into Asia, and we are very pleased with our choice of Kuhnil, which has the organizational and marketing infrastructure and capabilities for a successful commercial launch, which is expected to occur in 2019.

Patent Protection: We received a Notice of Allowance from the U.S. Patent & Trademark Office (USPTO) related to claims expanding the patent coverage of Consensi to include oral dosage compositions containing both amlodipine and celecoxib. The Notice of Allowance should result in the issuance of an additional patent that would further strengthen Kitov’s proprietary position and long-term U.S. market exclusivity for Consensi.

TyrNovo: NT219 – Small molecule oncology drug

We acquired a majority stake in TyrNovo, a private oncology company, which is developing NT219, a small molecule drug that presents a new and exciting concept in cancer therapy by attempting to address a major problem whose solution has been elusive to date – tumors’ developing cancer-drug resistance. NT219 is a unique compound that is designed to prevent and reverse resistance to anti-cancer drugs through dual inhibition of STAT3 and IRS1/2, two signal pathways associated with drug resistance. Kitov’s current ownership in TyrNovo is 65% and we have a pending transaction to increase our stake in TyrNovo to approximately 92%, expected to be closed in the next few weeks.

We are very pleased with this acquisition, its progress during 2017 and, most importantly, its long-term potential. NT219 has demonstrated impressive efficacy in large array of pre-clinical models with several leading targeted oncology drugs, with chemotherapy drugs and with Immuno-Oncology drugs in various cancer types, including in combination with Keytruda. Our development program is of critical importance, as we prepare for the start of human clinical trials in 2019.

Furthermore, we received the FDA’s response to NT219’s pre-IND meeting package. In its response, the FDA agreed to our preclinical and clinical development plans for NT219, and we are considering the initiation of clinical studies in combination with gemcitabine (Gemzar) for the treatment of pancreatic cancer and/or in combination with osimertinib (TagrissoTM) for the treatment of non-small cell lung cancer (NSCLC).

Our goal is to develop NT219 in combination with approved oncology drugs to increase efficacy, expand target populations and treatment duration. Our long-term strategy is to develop NT219 in combination with other oncology drugs and for additional oncology indications, on our own or in collaboration with potential strategic partners. Our preliminary partnering discussions for NT219 have yielded positive feedback, and this will be a focus area for TyrNovo throughout 2018.

OUTLOOK FOR 2018

Our major goals for 2018 are:

●To submit to the FDA our study report for the recently completed Phase III/IV renal function clinical trial for Consensi. We believe the clinical study report is of major significance in that it could strengthen the drug’s labeling and support future marketing of Consensi.

●Receive marketing approval for Consensi from the FDA.

●To successfully expand our business development efforts for Consensi by entering into additional distribution or licensing agreements in the U.S. and other target markets, with an emphasis on China and other countries in Asia.

●Make significant progress towards finalizing the submission of an IND application for NT219 to the FDA in order to pave the way for the start of clinical trials in 2019.

●Continue to strengthen our patent protection for both Consensi and NT219 through the submission of various patent applications and the expansion of our existing patent families.

I want to thank you, our shareholders, for the trust you have placed in us. Our board of directors and management team is committed to continuing to unlock the substantial value in our business by leveraging our team’s deep regulatory expertise and drug development experience, complemented by targeted business development efforts, in order to maximize the potential of our therapeutic candidates.

This past year has taught us all at Kitov a great deal about our team’s special human qualities and its determination, dedication, and commitment to face any challenge.

We look forward to providing you with further updates on our continued progress throughout 2018.

Best wishes for a successful year.

Kind regards,
Mr. Isaac Israel
Chief Executive Officer"

Sorrento Therapeutics Autologous Anti-CEA CAR-T Cell Therapy for Liver Metastases Demonstrates Therapeutic Activity in Stage IV Pancreas Cancer in a Phase 1b HITM-SURE Trial (NCT02850536)

On March 5, 2018 Sorrento Therapeutics, Inc. (NASDAQ:SRNE) ("Sorrento"), cellular therapy focused subsidiary, TNK Therapeutics, Inc. ("TNK"), and Surefire Medical, Inc., reported initial results from the Hepatic ImmunoTherapy for Metastases-Surefire, or HITM-SURE (NCT02850536), a Phase 1b single arm trial testing its autologous anti-CEA CAR-T cells administered regionally by hepatic artery infusion (HAI) via pressure directed microvalve infusion (MVI) technology (Surefire Infusion System, Surefire Medical, Inc., Westminster, Colorado) in heavily pre-treated patients with refractory CEA-positive liver metastases (LM) (Press release, Sorrento Therapeutics, MAR 5, 2018, View Source [SID1234532251]). This Phase 1b trial follows the HITM (NCT01373047) and HITM-SIR (NCT02416466) Phase 1 studies we believe demonstrated the safety and biological activity of the anti-CEA CAR-T administered with hepatic artery infusions (HAI) alone or with selective internal radiotherapy.

The data of HITM-SURE were provided by Dr. Steven Katz, the Principal Investigator of the Study and Associate Professor of Surgery at The Roger Williams Medical Center (CharterCare Health Partners and Prospect Medical Holdings). The study is also open at Colorado University and funded in part by the Colorado Office for Economic Development and International Trade.

In total, three patients have completed the ongoing HITM-SURE protocol, two with stage IV pancreatic cancer and one with colorectal cancer (LM). All patients presented with unresectable, chemotherapy refractory CEA+ liver metastases. Patients received three HAI of anti-CEA CAR-T cells (1e10 cells per dose) along with low dose IL-2 infusion (50,000 IU/kg/day, Proleukin, Prometheus). CAR-T HAI were administered via a Surefire MVI technology. The primary objective of the study was to establish the safety of the CAR-T HAI with the pressure directed MVI device. Secondary objectives included response assessed by modified RECIST (mRECIST), immune-related response criteria (irRC), and tumor marker kinetics. Reduction in post-treatment serum CEA was noted in all patients (average change 19 ng/mL, range 3.1-39 ng/mL). Two patients have progressive disease, with a pancreatic cancer patient alive at 7 months and a colorectal cancer patient alive at 4.8 months. A patient with stage IV pancreas adenocarcinoma has no evidence of liver metastases 11 months on PET scan following three CAR-T HAIs. In the phase III MPACT study, treatment of stage IV pancreas adenocarcinoma patients with gemcitabine plus albumin-bound paclitaxel resulted in a median overall survival time of 8.7 months. It will be of interest to determine if the results from upcoming phase 2 liver metastasis HITM studies will confirm the encouraging results from our small number of patients.

The initial findings from the currently enrolling HITM-SURE trial follows the results of two other trials. In one of the previous trials, a patient survived 51 months following 3 anti-CEA CAR-T HAIs and a patient from another trial is alive 25 months after treatment.

Dr. Katz noted, "In 15 patients in the Phase 1 and 1b studies, our CAR-T hepatic artery infusion method has resulted in highly selective delivery of CAR-T to liver tumors, with avoidance of severe cytokine release syndrome and neurotoxicity. We have observed encouraging clinical outcomes in heavily pre-treated patients. Future trials will test our novel delivery strategies for pancreatic and peritoneal tumors, in addition to novel combinatorial approaches to reverse organ-specific immunosuppressive pathways. We have developed a pipeline and delivery methods specifically tailored to address barriers to effective solid tumor CAR-T therapy, including the use of Surefire’s pressure-directed microvalve infusion technology to help overcome the high interstitial pressure of these tumors. The combination of CAR-T cells and this novel delivery mechanism are powerful tool for enhancing solid tumor uptake of CAR-T cells. Regional delivery of CAR-T cells has promise to be an important component of a multifaceted approach for advanced solid tumor patients."

"It is gratifying to observe that local infusion of CAR-T cells is very well tolerated and active in treating solid tumor metastases in the liver," said Dr. Jerome Zeldis, Sorrento Chief Medical Officer and President of TNK Therapeutics. "Based on these exciting data, we are now working on strategies to enhance the anti-solid tumor activity while lessening the complications typical of CAR-T therapy. In addition, we are planning on performing combination therapy studies using our CAR-T programs, including anti-CEA CAR-T, together with other Sorrento assets, such as our immuno-oncology checkpoint antibodies as well as Seprehvir, our clinical-stage oncolytic virus. The combination studies of anti-CEA CAR-T and Seprehvir should initiate the second half of 2018."

"We are pleased with the strong progress Merck has made in the development of our anti-CD27 antibody," stated Hans van Eenennaam, Ph.D., executive vice president of antibody research and site head, Aduro Biotech Europe. "This marks an important step forward in the advancement of our proprietary B-select monoclonal antibody technology, as the second antibody to enter the clinic."

About CD27 and Aduro’s Anti-CD27 Antibody
CD27 is a co-stimulatory receptor expressed on different immune cells, such as T-lymphocytes and NK (natural killer) cells. It has been recognized as having an important role in priming, enhancing and sustaining a productive anti-cancer (CD8 T-cell) adaptive immune response. In preclinical studies, anti-CD27 activation was shown to enhance T-cell response, which in combination with immune checkpoint inhibition demonstrated the ability to achieve complete tumor eradication.

In 2014, Merck, through certain affiliates, entered into a worldwide license agreement for the development and commercialization of CD27 antibody agonists. Aduro’s anti-CD27 antibody, which was identified with its proprietary B-select monoclonal antibody technology, targets a functional epitope on CD27 demonstrating potent activation of the CD27 co-stimulatory pathway in pre-clinical studies. As a part of the worldwide license agreement, and in addition to payments received, including the $15 million up-front payment, Aduro is eligible to receive future development, commercial and net sales milestone payments. In addition, Aduro is eligible to receive royalties in the mid-single digits to low teens based on any net sales of the product, if it is approved for marketing.
