EORTC researchers discover a treatment for drug-resistant GIST

On May 26, 2020 EORTC reported that Although there are effective treatments for advanced gastrointestinal tumours (GISTs) most patients with this rare disease will eventually become resistant to them (Press release, EORTC, MAY 26, 2020, View Source [SID1234558458]). Finding a drug that will help those patients where treatment has failed is therefore a priority. Now, for the first time, EORTC researchers have identified that the oral agent cabozantinib has clinically relevant anti-tumour activity in patients whose disease was progressing despite treatment with two other anticancer drugs. The research is published in The European Journal of Cancer.

"Based on very promising findings from my laboratory in self-made, patient-derived mouse models of GIST, we designed a multicentre European clinical trial using cabozantinib in patients who had come resistant to imatinib (Glivec) and sunitinib (Sutent)," said Professor Patrick Schöffski, Head of the Department of General Medical Oncology, University Hospitals Leuven, and of Laboratory for Experimental Oncology, KU Leuven, Leuven Cancer Institute, Leuven, Belgium, who led the investigation for the EORTC Soft Tissue and Bone Sarcoma Group.

"The excellent results of this Phase 2 trial are fully in line with our preclinical data in self-made mouse models of human GIST and confirm once again the predictive character of mouse xenograft work. The working hypothesis that cabozantinib is active in advanced GIST was confirmed, as the trial met its primary endpoint, without any new safety signal detected."

GIST is a rare tumour that occurs most commonly in the stomach or small intestine, and the most common sarcoma in the gastrointestinal tract. The tumours grow from specialised cells found in the gastrointestinal tract called interstitial cells of Cajal (ICCs). GISTs are usually found in adults aged between 40 and 70, but can also occur at younger ages, and even in children.

In the seven-country, academic, investigator-initiated clinical study, 50 patients started treatment with cabozantinib between February 2017 and August 2018. Among the first 41 who were evaluable, 24 had no worsening of disease (‘progression-free’) at week 12. At the end of the trial, the disease had been controlled in 41 of the patients, whereas in eight the disease had progressed despite treatment with cabozantinib, and one was not evaluable – an impressive disease control rate of 82%, particularly when considering the fact that patients had already failed two other established anticancer agents.

Now that clinically relevant anti-tumour activity of cabozantinib has been demonstrated in patients with advanced GIST in whom other treatments had failed, the researchers suggest that the drug should become available for such patients outside clinical trials. "The oral agent was active in all genetically-defined subsets of patients in this trial. The impressive findings of this study should be followed by a more definitive, randomised, blinded Phase 3 trial comparing cabozantinib with placebo or another available agent," says Prof Schöffski.

Cellectar Receives FDA Fast Track Designation for CLR 131 in Lymphoplasmacytic Lymphoma/ Waldenstrom’s Macroglobulinemia

On May 26, 2020 Cellectar Biosciences, Inc. (NASDAQ: CLRB), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of drugs for the treatment of cancer, reported the U.S. Food and Drug Administration (FDA) has granted Fast Track Designation for CLR 131 in lymphoplasmacytic lymphoma (LPL)/Waldenstrom’s macroglobulinemia (WM) in patients having received two prior treatment regimens or more (Press release, Cellectar Biosciences, MAY 26, 2020, View Source [SID1234558455]). CLR 131 is the company’s small-molecule, cancer-targeting radiotherapeutic Phospholipid Drug Conjugate (PDC) designed to deliver cytotoxic radiation directly and selectively to cancer cells and cancer stem cells. It is currently being evaluated in Cellectar’s ongoing Phase 2 CLOVER-1 clinical study in patients with relapsed or refractory multiple myeloma and lymphoplasmacytic lymphoma/Waldenstrom’s macroglobulinemia.

"LPL/WM patients that do not respond optimally or are intolerant of ibrutinib, currently have limited treatment options and poor survival rates. Fast Track Designation for LPL/WM further supports our clinical development strategy to quickly and efficiently provide these patients with an effective therapeutic alternative," said James Caruso, president and CEO of Cellectar. "All four LPL/WM patients treated in our CLOVER-1 Phase 2 study to date achieved a 100% overall response rate and a 25% complete response rate. This strong response rate may represent an important improvement in the treatment of relapsed/refractory LPL/WM as no approved or late-stage development treatments for relapsed or refractory patients have reported complete responses."

Cellectar announced that it had received Orphan Drug Designation (ODD) for CLR 131 in LPL earlier this year. In addition to the variety of benefits derived from the ODD, the company will also receive increased engagement and assistance from the FDA in support of the regulatory approval pathway for LPL/WM.

Fast Track Designation

Fast Track Designation is granted to drugs being developed for the treatment of serious or life-threatening diseases or conditions where there is an unmet medical need. The purpose of the Fast Track Designation provision is to help facilitate development and expedite the review and potential approval of drugs to treat serious and life-threatening conditions. Sponsors of drugs that receive Fast Track Designation have the opportunity for more frequent interactions with the FDA review team throughout the development program. These can include meetings to discuss study design, data required to support approval, or other aspects of the clinical program. Additionally, products that have been granted Fast Track Designation may be eligible for priority review of a New Drug Application (NDA) Real Time Oncology Review (RTOR) by the FDA which allows the FDA to begin review of the data within weeks of concluding the pivotal study.

About LPL/WM

Waldenstrom’s macroglobulinemia (WM) is a lymphoma, or cancer of the lymphatic system. The disease occurs in a type of white blood cell called a B-lymphocyte or B-cell, which normally matures into a plasma cell whose job is to manufacture immunoglobulins (antibodies) to help the body fight infection. In WM, there is a malignant change to the B-cell in the late stages of maturing, and it continues to proliferate into a clone of identical cells, primarily in the bone marrow but also in the lymph nodes and other tissues and organs of the lymphatic system. These clonal cells over-produce an antibody of a specific class called IgM.

WM cells have characteristics of both B-lymphocytes and plasma cells, and they are called lymphoplasmacytic cells. For that reason, WM is classified as a type of non-Hodgkin’s lymphoma called lymphoplasmacytic lymphoma (LPL). About 95% of LPL cases are WM; the remaining 5% do not secrete IgM and consequently are not classified as WM. WM is a very rare and incurable disease.

About CLR 131

CLR 131 is a small-molecule Phospholipid Drug Conjugate designed to provide targeted delivery of iodine-131 (radioisotope) directly to cancer cells, while limiting exposure to healthy cells unlike many traditional on-market treatment options. CLR 131 is the company’s lead product candidate and is currently being evaluated in a Phase 2 study in B-cell lymphomas, and a Phase 1 dose-escalating clinical study in pediatric solid tumors and lymphoma. The company recently completed a Phase 1 dose-escalation clinical study in r/r multiple myeloma. The FDA granted CLR 131 Fast Track Designation for both r/r multiple myeloma and r/r diffuse large b-cell lymphoma and Orphan Drug Designation (ODD) for the treatment of multiple myeloma, lymphoplasmacytic lymphoma/Waldenstrom’s macroglobulinemia, neuroblastoma, rhabdomyosarcoma, Ewing’s sarcoma and osteosarcoma. CLR 131 was also granted Rare Pediatric Disease Designations for the treatment of neuroblastoma, rhabdomyosarcoma, Ewing’s sarcoma and osteosarcoma. Most recently, the European Commission granted an ODD for r/r multiple myeloma.
