+Added: Concludes Phase 1b and Opens Recruitment in MB-107 Phase 2 Clinical Trial of Annamycin for the Treatment of Soft Tissue Sarcoma Lung Metastases
+Added: On July 28, 2022, we announced that with five US sites active in our MB-107 clinical trial, the safety review of the fourth cohort in a dose escalation clinical trial evaluating Annamycin for the treatment of soft tissue sarcoma (STS) lung metastases was completed, thus concluding the Phase 1b portion of our U.S.
+Added: Phase 1b/2 clinical trial.
+Added: The trial began in June of 2021.
+Added: Preliminary results from the study continue to document clinical activity for Annamycin in the treatment of STS.
+Added: The safety review committee (SRC) deemed the dose of 390 mg/m 2 to be safe after conclusion of the fourth cohort.
+Added: Notwithstanding that this dose level was deemed to be safe, tolerability issues present at the 390 mg/m 2 dose level caused delays in follow-on cycles and the reduction of subsequent doses, suggesting that a Recommended Phase 2 Dose (RP2D) below 390 mg/m 2 was warranted.
+Added: Consistent with the recommendation of the SRC, we determined that the RP2D will be 360 mg/m 2 for the first three subjects in the Phase 2 portion of the study.
+Added: The SRC will then review the clinical safety data at this dose and determine whether the RP2D should be further reduced to 330 mg/m 2 prior to proceeding with the additional 22 subjects.
+Added: In addition to continuing to assess safety, including gathering additional information about short-term side effects and possible risks, this Phase 2 portion of the study will also explore the efficacy of Annamycin as a single agent for the treatment of subjects with STS lung metastases for whom prior chemotherapy has failed, and for whom new chemotherapy is considered appropriate.
+Added: In the Phase 1b portion of the study, 15 subjects were enrolled and treated per the protocol in four cohorts to determine the maximum tolerable dose and/or the RP2D.
+Added: Each cohort had three subjects, except for the fourth cohort, which (per the protocol) was expanded to six subjects after a dose-limiting toxicity occurred in a single subject.
+Added: Up to 28 subjects, to account for potential over enrollment, will be enrolled at the RP2D in Phase 2 to focus more on quantifying efficacy as well as providing additional safety information.
+Added: Of the fifteen subjects treated per the protocol, two continue with treatment, and eight subjects have been followed without evidence of disease progression for two months or greater, with three of the eight free of disease progression for 120 days or more.
+Added: These data are early-stage, preliminary and subject to change, and there is no guarantee that such results will be replicated in the Phase 2 portion of the trial.
