Athenex Announces Positive Second Cohort Results of Oraxol-plus-Ramucirumab Phase 1b Clinical Trial in Gastric Cancer

On December 11, 2018 Athenex, Inc., a global biopharmaceutical company dedicated to the discovery, development and commercialization of novel therapies for the treatment of cancer, reported that its global Phase 1b clinical trial of Oraxol (oral paclitaxel plus HM30181A) plus ramucirumab (monoclonal antibody to VEGF-R2) in gastric cancer patients who failed previous chemotherapies has completed the study of the second cohort of patients (Press release, Athenex, DEC 11, 2018, View Source;p=RssLanding&cat=news&id=2380209 [SID1234532013]). The results indicated strong positive signals of efficacy and the treatment was well tolerated.

In the first cohort of six patients treated with a 200 mg/kg dose of Oraxol, partial responses were observed in 2/6 patients (33.3%) and stable disease observed in 1/6 patient (16.7%). There was one severe adverse event (SAE) of grade-4 neutropenia in one patient who had complete recovery from this event.

Athenex now reports that for the second cohort of six patients on an escalated Oraxol dose of 250 mg/kg, partial response, according to RECIST criteria, occurred in 3 patients (50%). There was one SAE of grade-3 vomiting in one patient, who elected to withdraw from the study and subsequently had complete recovery. The Oraxol dose is currently being further escalated to 300 mg/kg in the third cohort of patients and the study is ongoing.

"We are pleased by the strong positive signals of efficacy together with a good safety profile in this Phase 1b clinical trial of Oraxol plus ramucirumab in the second-line treatment of gastric cancer patients so far and look forward to further results from the continuation of this study. The results also echoed the strong positive signal that we have observed in other clinical studies of Oraxol as monotherapy for the treatment of metastatic breast cancer," stated Dr. Rudolf Kwan, Athenex’s Chief Medical Officer.

Oraxol is a novel oral formulation of paclitaxel currently in Phase 3 clinical trial in metastatic breast cancer.

Ramucirumab, as a single agent or in combination with paclitaxel, is FDA-approved for the treatment of patients with advanced or metastatic, gastric or gastroesophageal junction (GEJ) adenocarcinoma with disease progression on or after prior fluoropyrimidine- or platinum-containing chemotherapy. Ramucirumab is manufactured and marketed by Eli Lilly and Company under the name CYRAMZA.

The Orascovery platform was initially developed by Hanmi Pharmaceuticals and licensed exclusively to Athenex for all major worldwide territories except Korea, which is retained by Hanmi.

PharmaEssentia Corp. licensed the Taiwan, Singapore and Vietnam rights of Oraxol from Athenex and is a partner in the development of Oraxol in the territory

Cellectar Granted Japanese Patent for CLR 131

On December 11, 2018 Cellectar Biosciences, Inc. (Nasdaq: CLRB), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of targeted treatments for cancer, reported that the Japan Patent Office has granted the patent titled "Phospholipid Analogs as Diapeutic Agents and Methods of Use Thereof" with application number 2016135920 (Press release, Cellectar Biosciences, DEC 11, 2018, View Source [SID1234532012]). The patent provides composition of matter and use protection for the company’s proprietary phospholipid ether (PLE) analogs and specifically CLR 131 in breast, brain, leukemias and a variety of other cancers.

"Certain cancers such as pediatric lymphomas and leukemias have a higher prevalence in Asia and represent unmet need both within and outside the region," said Jim Caruso, president and chief executive officer of Cellectar Biosciences. "The issuance of this patent enhances our growing intellectual property portfolio in this strategically important market and provides incremental value to CLR 131 and our PLE delivery franchise."

About Phospholipid Drug Conjugates

Cellectar’s product candidates are built upon a patented delivery and retention platform that utilizes optimized phospholipid ether-drug conjugates (PDCs) to target cancer cells. The PDC platform selectively delivers diverse oncologic payloads to cancerous cells and cancer stem cells, including hematologic cancers and solid tumors. This selective delivery allows the payloads’ therapeutic window to be modified, which may maintain or enhance drug potency while reducing the number and severity of adverse events. This platform takes advantage of a metabolic pathway utilized by all tumor cell types in all cell cycle stages. Compared with other targeted delivery platforms, the PDC platform’s mechanism of entry does not rely upon specific cell surface epitopes or antigens. In addition, PDCs can be conjugated to molecules in numerous ways, thereby increasing the types of molecules selectively delivered. Cellectar believes the PDC platform holds potential for the discovery and development of the next generation of cancer-targeting agents.

About CLR 131

CLR 131 is Cellectar’s investigational radioiodinated PDC therapy that exploits the tumor-targeting properties of the company’s proprietary PLE and PLE analogs to selectively deliver radiation to malignant tumor cells, thus minimizing radiation exposure to normal tissues. CLR 131 is in a Phase 2 clinical study in relapsed/refractory multiple myeloma (R/R MM) and a range of B-cell malignancies, and a Phase 1b clinical study in patients with R/R MM exploring fractionated dosing. The objective of the multicenter, open-label, Phase 1b dose-escalation study is the characterization of safety and tolerability of CLR 131 in patients with R/R MM. Patients in Cohorts 1-4 received single doses of CLR 131 ranging from 12.5 mCi/m2 to 31.25 mCi/m2 as well as a fractionated dose of 15.625 mCi/m2 given twice over seven days in Cohort 5. All study doses and regimens have been deemed safe and well tolerated by an independent Data Monitoring Committee. The company plans to initiate a Phase 1 study with CLR 131 in pediatric solid tumors and lymphoma as well as a second Phase 1 study in combination with external beam radiation for head and neck cancer.
