XOMA`s Human Engineered ING-1 Cancer Antibody Shows Encouraging Clinical Safety Profile and Low Immunogenicity in Patients Clinical Data Reported at ASCO
BERKELEY, Calif.--(BW HealthWire)--May 20, 2002--Results of a Phase I clinical study of XOMA Ltd.`s (Nasdaq:XOMA - News) Human Engineered(TM) ING-1(heMab) monoclonal antibody in patients with solid tumors show safety and tolerability results that support further clinical development, according to research presented at the 38th Annual Meeting of the American Society of Clinical Oncologists (ASCO) in Orlando, Florida. Additional data presented at the meeting suggest that XOMA`s patented Human Engineering(TM) methodology effectively yields therapeutic antibodies with minimal immunogenicity in humans, comparable to antibody humanization methods.
"We were pleased to show not only that ING-1 was well tolerated by the cancer patients treated in this study, but also that this Human Engineered(TM) antibody is similar in immunogenicity to monoclonal antibodies than have been modified by other humanization methods," said Marc Better, PhD, vice president of technical development at XOMA. "The Human Engineering(TM) technology was developed at XOMA, and further demonstrates our company`s long-held expertise in the field of monoclonal antibody engineering and development."
Safety and Tolerability of ING-1
The open-label, dose-escalating Phase I study was conducted at the University of Alabama Comprehensive Cancer Center and the Cancer Therapy and Research Center in San Antonio, Texas. This study was designed to evaluate the safety, tolerability, immunogenicity and pharmacokinetics of intravenously administered ING-1(heMab) in patients with advanced adenocarcinomas of the breast, GI tract (colorectal, pancreatic, gastric, esophageal), lung, ovary, and prostate refractory to standard therapies.
Twenty-two advanced adenocarcinoma patients received a median of two courses of ING-1(heMAb) as a one-hour infusion at one of four dose levels: 0.03, 0.1, 0.3 or 1.0 mg/kg. Dose-limiting reversible events (amylase and lipase elevations with abdominal pain) were seen at 1 mg/kg, precluding further dose escalation. Adverse events were mild at doses of 0.3 mg/kg or less, and included rigors, chills and mild fever that responded well to antipyretics and antihistamines. Although efficacy was not an endpoint, investigators reported no objective tumor responses in this short-term study, but two patients had stable disease at three months. The maximum tolerated dose of ING-1 given intravenously every 21 days was 0.3 mg/kg and, at that dose, the ING-1(heMAb) half-life was 30.6 +/- 3.4 hours (mean +/- S.E.), and at that dose, the antibody reached plasma concentrations that have showed anti-tumor activity in preclinical models.
"The relatively brief half-life and good tolerability seen for ING-1 in this study have encouraged our further exploration of this antibody at a weekly dosing schedule," said Dr. Better. "We have now completed enrollment in a second ING-1 study, and expect to begin enrollment in an additional study soon, including an evaluation of subcutaneous administration."
ING-1 Immunogenicity
ING-1 is the first Human-Engineered(TM) antibody to be administered in human clinical studies. This patented technology is an alternative to other methods used to minimize immunological reactions by human patients to antibodies of rodent or other non-human origins. Such reactions can preclude repeated dosing with the same antibody, among other problems. Ideally, modified antibodies are invisible to the human patient`s immune system while retaining the binding affinity and therapeutic activity of the non-human antibody.
To evaluate ING-1`s immunogenicity in patients, the investigators evaluated blood samples from the 22 participants in the Phase I clinical trial for antibody response to ING-1. Of 17 evaluable patients, only two had a detectable immune response to ING-1, one patient after 2 doses, and another after 3 doses of 0.3 mg/kg. These data suggest that Human-Engineered(TM) ING-1 is comparable in immunogenicity to humans to therapeutic antibodies humanized using other methods.

Hallo hört sich gut an aber wie sieht es mit einer Übersetzung aus Danke
@Big(?)Linus
Was macht das für einen Sinn, eine bereits 1 Monat alte Meldung,die im Kurs schon längst verarbeitet ist, jetzt ins Board zu stellen?
Warst wohl selbst unzufrieden mit dem Kursverlauf!
Vor allen Dingen haben dich wahrscheinlich die gestrigen
-16,44% (incl. nachbörslich) nicht einschlafen lassen.

@ rainer271
Ich bin mit dem Kursverlauf nur insoweit unzufrieden, als ich die Gelegenheit für eine Absenkung meiner Einstiegskurse genutzt habe.
Wenn dir diese Info bereits bekannt war, warum hast du sie dann nicht schon längst gepostet? Für mich war diese Info jedenfalls neu.
