-
First clinical data reported for this novel antibody-drug conjugate
(ADC) for ovarian, breast, and other epithelial cancers.
-
First of four partner compounds with clinical data presentations
expected this quarter.
WALTHAM, Mass.--(BUSINESS WIRE)--
ImmunoGen, Inc. (Nasdaq: IMGN) today announced the presentation of
interim data from the ongoing Phase I trial of Sanofi's SAR566658 at the
AACR-NCI-EORTC International Conference on Molecular Targets and Cancer
Therapeutics meeting (abstract #A73) being held in Boston. SAR566658 is
an ADC targeted to CA6, which is found on many cases of ovarian, breast,
and other epithelial cancers. The data reported support that SAR566658
is generally well tolerated and can induce objective responses and
sustained stable disease in heavily pretreated patients with
CA6-positive cancers.
SAR566658 was created by ImmunoGen and licensed preclinically to Sanofi
as part of a broader collaboration between the companies. It comprises
the Company's huDS6 CA6-targeting antibody with one of ImmunoGen's
proprietary cell-killing agents (DM4) attached using one of its
engineered linkers (SPDB). The interim findings reported today are from
the dose-finding part of the first SAR566658 clinical trial.
A total of 34 patients received SAR566658 at doses ranging from 10-240
mg/m2 (6.5 mg/kg), administered every three weeks. Overall,
SAR566658 was well tolerated, with limited adverse events typically
associated with cytotoxic chemotherapy (hematologic toxicity, peripheral
neuropathy). Reversible ocular corneal changes were seen at the higher
doses. The recommended dose for further evaluation was determined to be
190 mg/m2, and SAR566658 is now being assessed at that
dose in the extension phase of the trial.
Among the 20 patients who received SAR566658 at doses of 120 mg/m2
(3.2 mg/kg) or more, there were two partial responses (PR), two
unconfirmed PRs, and nine with stable disease.
"These early clinical data indicate SAR566658 is generally well
tolerated and can have anticancer activity against heavily pretreated
CA6-positive tumors," commented John Lambert, PhD, EVP and Chief
Scientific Officer. "They also provide further support that our
maytansinoid ADC technology can achieve active, well-tolerated
anticancer compounds."
