One of the key presentations, titled (Abstract #H14) ‘Development of a new and improved delivery system for lanreotide autogel/depot to further enhance care for patients with NETs and acromegaly’, reports results from five separate, but complementary studies designed to inform and test enhancements to the existing Somatuline Autogel (lanreotide) pre-filled syringe.1

Input from patients and their caregivers, as well as nurses and other healthcare professionals, was used to design a new pre-filled syringe1 that was submitted to the European Union as a type II variation via a work-sharing procedure with HPRA (Ireland) as the reference country. Following a positive outcome of the work-sharing procedure, each member state would consider a national approval. Notable new features are modified ergonomics and handling, a needle shield removal system, an injection process with plunger support and heightened ease of use.1

"It is our mission to ensure patients continue to receive optimized care as they navigate the challenges of living with NETs and acromegaly," said Sotirios Stergiopoulos, Chief Medical Officer at Ipsen. "The data we are sharing at this year’s ENETS conference underscores our commitment to understanding the patient experience and to supporting a multidisciplinary treatment approach to make treatment administration as simple as possible whether in hospital or at home."

"For nurses and other healthcare practitioners treating patients with NETs or acromegaly, the value of innovation across the entire treatment landscape supports our ability to provide the best care for our patients," said Daphne T Adelman, Clinical Nurse Specialist from Northwestern University in Chicago, U.S. and one of the authors of the study. "As a nurse who administers treatments to patients often, efficient pre-filled syringes allow me to save time and focus on patients and their needs."

Also, being highlighted are results from:

About SOMATULINE2

Somatuline Autogel is made of the active substance lanreotide, which is a long-acting somatostatin analogue that inhibits the secretion of growth hormone and certain hormones secreted by the digestive system. The main indications of Somatuline and Somatuline Autogel are:2

The treatment of individuals with acromegaly when the circulating levels of Growth Hormone (GH) and/or Insulin-like Growth Factor-1 (IGF-1) remain abnormal after surgery and/or radiotherapy, or in patients who otherwise require medical treatment.
The treatment of grade 1 and a subset of grade 2 (Ki-67 index up to 10%) gastroenteropancreatic neuroendocrine tumors (GEP-NETs) of midgut, pancreatic or unknown origin where hindgut sites of origin have been excluded, in adult patients with unresectable locally advanced or metastatic disease.
The treatment of symptoms associated with neuroendocrine (particularly carcinoid) tumors.
Important Safety Information

The detailed recommendations for the use of Somatuline Autogel are described in the Summary of Product Characteristics (SmPC), available here.
About XERMELO3

Xermelo is a novel, orally administered, inhibitor of the enzyme tryptophan hydroxylase (TPH). Through inhibition of TPH, the rate-limiting step in the synthesis of serotonin, Xermelo was designed to reduce the production of serotonin within neuroendocrine tumors.

Xermelo (telotristat ethyl) is commercialized by Ipsen in all territories excluding the United States and Japan, where Lexicon retains the rights. Lexicon has approval for Xermelo in the U.S. as a first and only orally administered therapy for the treatment of carcinoid syndrome diarrhea in combination with somatostatin analog (SSA) therapy in adults inadequately controlled by SSA therapy.

Xermelo is approved in Europe for the treatment of carcinoid syndrome diarrhea in patients inadequately controlled by somatostatin analogue therapy.

Important Safety Information

The detailed recommendations for the use of Xermelo are described in the Summary of Product Characteristics (SmPC), available here.

On February 27, 2019 ALX Oncology, a clinical-stage immuno-oncology company developing therapies to block the CD47 checkpoint mechanism, reported that preclinical data for its SIRPα antibody research program will be presented at the 2019 Keystone Symposia Conference (Keystone), Cancer Immunotherapy in Whistler, British Columbia and the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2019 in Atlanta, Georgia (Press release, ALX Oncology, FEB 27, 2019, View Source [SID1234533751]).

CD47/SIRPα interaction is a key checkpoint mechanism exploited by cancer cells to escape immunological surveillance. While CD47 is widely expressed in human cells, SIRPα, the CD47 inhibitory receptor, is mainly expressed in myeloid cells and neurons. ALX148, a CD47 blocker with an inactive Fc domain, is generally well tolerated and demonstrates anti-cancer activity in combination with trastuzumab and pembrolizumab in patients with anti-HER2 and checkpoint inhibitor resistant/refractory disease (SITC 2018, P335). Another approach to block this interaction is to target SIRPα.

"Targeting the CD47/SIRPα pathway is an exciting new approach that shows promise in clinical trials. By targeting SIRPα, we can investigate the similarities and differences of an orthogonal strategy to inhibit this axis," said Hong Wan, Ph.D., ALX Oncology’s Chief Scientific Officer. "Our panel of proprietary high affinity monoclonal antibodies provides diverse epitope coverage across the extracellular surface of SIRPα. These antibodies are cross-reactive to human, monkey and rodent SIRPα variants, which enables robust clinical translation. Importantly, these antibodies bind to all human SIRPα variants, a critical attribute for a global patient population."

ALX Oncology’s SIRPα antibodies enhance the antitumor activity of immune checkpoint inhibitors, with reduction of metastases, eradication of tumors, and acquisition of memory immune response in tumor-bearing mice with intact immune systems. The cellular immune response in syngeneic models shows that these SIRPα antibodies enhance innate and adaptive anti-cancer immunity, providing a rationale for combination with other immunotherapies. In an exploratory toxicology study in monkeys, the selected SIRPα antibodies demonstrate a favorable pharmacokinetic, target occupancy and tolerability profile.

Together, these preclinical data provide a compelling rationale to advance the development of anti-SIRPα therapy for patients with cancer.

"Decades of research have shown that tetracyclines hold potential as anticancer agents, but to date, optimizing a tetracycline for oncology has proven elusive," said Guy Macdonald, President and Chief Executive Officer. "Leveraging our proprietary and productive discovery platform, we identified TP-2846, a structurally diverse tetracycline and potential new antileukemia agent with potent in vitro and in vivo activity. We look forward to further discussing the potential of TP-2846 at AACR (Free AACR Whitepaper) and building on this encouraging preclinical dataset."

"TP-2846 represents a new mechanism of action with potential application for AML patients regardless of mutation status," said Jacques Dumas, Ph.D., Chief Scientific Officer. "By using our fully synthetic technology for building tetracyclines, we have been able to optimize TP-2846 for AML, warranting its further study in this patient population."
