"We are delighted to see this publication that reinforces momelotinib as the potential JAK inhibitor of choice for myelofibrosis patients with anemia—a need that is currently not met with approved JAK inhibitors. We look forward to sharing MOMENTUM topline data the end of January 2022," said Stephen Dilly, MBBS, PhD, President and Chief Executive Officer at Sierra Oncology.

Myelofibrosis is characterized by constitutional symptoms, including fatigue, body and bone pain and excessive sweating or fever; splenomegaly (enlarged spleen); and anemia. Moderate-to-severe anemia afflicts 40-60% of myelofibrosis patients at the time of diagnosis and increases to up-to 90% of patients over time.1 Anemia is a predictor of reduced overall survival and is associated with a nearly four-fold increase in the risk of death compared to no anemia, with a median survival of just 2.1 years.2,3

While JAK inhibitors are the mainstay of treatment options for myelofibrosis patients, currently approved JAK inhibitors cause myelosuppression, worsening anemia and creating poorer outcomes for patients. This profile creates a critical gap in the myelofibrosis treatment landscape and the need for a therapy that can address all three hallmarks of disease.

The authors noted in the publication, "Momelotinib’s mechanism of action uniquely positions it amongst approved and late-stage JAK inhibitors to be able to significantly alleviate the inflammation-driven, iron-restricted anemia of MF [ myelofibrosis] and eliminate/prevent RBC [red blood cell] transfusion dependence in a significant portion of MF patients besides treating the other two cardinal features of MF (splenomegaly and constitutional symptoms)."

About Momelotinib

Momelotinib is a selective and orally bioavailable JAK1, JAK2 and ACVR1 / ALK2 inhibitor for the potential treatment of myelofibrosis. Myelofibrosis results from dysregulated JAK-STAT signaling and is characterized by constitutional symptoms, splenomegaly (enlarged spleen) and progressive anemia.

Momelotinib is currently under investigation in the MOMENTUM clinical trial, a global, randomized, double-blind Phase 3 study for symptomatic and anemic myelofibrosis patients. The study enrolled 195 patients based on a planned 180 patients across 21 countries. Topline data are anticipated by the end of January 2022, and assuming positive results, the company intends to file an NDA with the FDA in the second quarter of 2022.

GP-2250 is a broadly active, tumor cell selective, small molecular weight, metabolic enzyme inhibitor with a first-in-class mechanism of action that limits aerobic glycolysis and Krebs cycle by inhibiting GAPDH, alpha-ketoglutarate dehydrogenase, pyruvate dehydrogenase, and the tumor promotor NFkB. In preclinical research, it suppresses cancer cells largely by disrupting their energy metabolism—bringing about cancer cell death.

The ASCO (Free ASCO Whitepaper) Gastrointestinal Cancers Symposium abstract and poster describe a dose-escalation trial of GP-2250 (NCT03854110) in combination with gemcitabine in the 2nd-line treatment of metastatic pancreatic cancer patients who have progressed on or after FOLFIRINOX in the 1st-line treatment of the disease. The primary endpoints in the trial are the maximum tolerated dose ("MTD") and recommended Phase 3 dose.

"To date, we believe our GP-2250 has demonstrated strong effectiveness and safety in extensive preclinical studies, and its early clinical results have been encouraging for its initial indication for pancreatic cancer," said Greg Bosch, Chairman & Chief Executive Officer of Panavance. "We’re pleased with the progress of our ongoing Phase 1 trial which is currently at the 6th dose level with more than 20 patients enrolled thus far."

While Panavance’s initial area of focus is on pancreatic cancer, the company is conducting additional preclinical research in several other tumor types and expects to progress clinical development of GP-2250 for the treatment of other cancers.

ITM Presents Study Design of COMPOSE Phase III Trial with ITM-11 (n.c.a. 177Lu-edotreotide) for Treatment of Neuroendocrine Tumors at ASCO-GI

On January 19, 2022 ITM Isotope Technologies Munich SE (ITM), a leading radiopharmaceutical biotech company, reported the presentation of the study design for its phase III trial, COMPOSE (NCT04919226), at the ASCO (Free ASCO Whitepaper) Gastrointestinal Cancers Symposium (ASCO-GI), held from January 20 – 22, 2022 (Press release, , 19 19, 2022, View Source [SID1234605661]). COMPOSE will evaluate the company’s lead radiopharmaceutical candidate, ITM-11 (n.c.a. 177Lu-edotreotide), compared to best standard of care in patients with well‐differentiated high grade 2 and grade 3 somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors (G2+G3 SSTR+ GEP-NETs). ITM-11 consists of the high-quality radioisotope, no-carrier-added lutetium-177 (n.c.a. 177Lu) chelated to the somatostatin analogue edotreotide. The aim of the study, in which patients are currently being randomized, is to evaluate the efficacy and safety of the Targeted Radionuclide Therapy in this high-need indication. COMPOSE is ITM’s second phase III trial with ITM-11 following and building upon COMPETE (NCT03049189), in patients with grade 1 and grade 2 GEP-NETs. Sponsor of the COMPOSE study is ITM’s subsidiary ITM Solucin GmbH.

"We look forward to presenting the study design of COMPOSE to the medical and scientific community at ASCO (Free ASCO Whitepaper)-GI given the significant potential of ITM-11 as an innovative treatment modality," commented Philip E. Harris, MD PhD, Chief Medical Officer at ITM. "The favorable safety profile and efficacy signals observed to-date with our lead candidate give us reason to believe that ITM-11 can provide an important clinical benefit to patients diagnosed with this high-need indication and an advanced stage of this cancer."

COMPOSE (NCT04919226) is an international, prospective, randomized, controlled, open-label, multi-center phase III clinical trial to evaluate the efficacy, safety, and patient-reported outcomes of first or second-line treatment with ITM-11 compared to best standard of care in patients with well-differentiated high grade 2 and grade 3 (Ki-67 index 15-55), SSTR+ GEP-NETs. The study aims to randomize 202 patients 1:1 to ITM-11 or to best standard of care — either chemotherapy (CAPTEM or FOLFOX) or everolimus — according to the investigator’s choice. The primary endpoint of the study is progression-free survival (PFS), which will be assessed every 12 weeks from randomization onwards. Secondary outcome measures include overall survival (OS) up to two years after disease progression.

"With poor prognoses and limited treatment options for GEP-NETs, COMPOSE is an important step toward addressing a patient population with a high unmet medical need," commented Thorvardur Ragnar Halfdanarson, Principal Investigator of COMPOSE at the Mayo Clinic, Rochester, MN, USA. "Targeted Radionuclide Therapy continues to demonstrate promise for the treatment of hard-to-treat tumors. As such, I look forward to investigating its potential for patients with advanced GEP-NETs as we move ITM-11 through this Phase III trial."

About Targeted Radionuclide Therapy

Targeted Radionuclide Therapy is an emerging class of cancer therapeutics, which seeks to deliver radiation directly to the tumor while minimizing radiation exposure to normal tissue. Targeted radiopharmaceuticals are created by linking a therapeutic radioisotope to a targeting molecule (e.g., peptide, antibody, small molecule) that can precisely recognize tumor cells and bind to tumor-specific characteristics, like receptors on the tumor cell surface. As a result, the radioisotope accumulates at the tumor site and decays, releasing a small amount of ionizing radiation, thereby destroying tumor tissue. The highly precise localization enables targeted treatment with minimal impact to healthy surrounding tissue.

About ITM-11 (n.c.a. 177Lu-edotreotide)

ITM-11, ITM’s therapeutic radiopharmaceutical candidate being investigated in the phase III clinical studies COMPETE and COMPOSE, consists of two components: the medical radioisotope no-carrier-added lutetium-177 (n.c.a. 177Lu) and the targeting molecule edotreotide, a synthetic form of the peptide hormone somatostatin that targets neuroendocrine tumor-specific receptors. Edotreotide binds to these receptors and places the medical radioisotope n.c.a. lutetium-177 directly onto the diseased neuroendocrine cells so that it accumulates at the tumor site. N.c.a. lutetium-177 is internalized into the tumor cells and decays, releasing medical radiation (ionizing β-radiation) with a maximum radius of 1.7 mm and destroying tumor tissue. The highly precise localization can result in the healthy tissue surrounding the targeted tumor being minimally affected.
