Industry News: Insightec receives FDA IDE approval for prostate cancer comparative study using high intensity focused ultrasound

Insightec announced that it has received FDA approval for an investigational device exemption (IDE) for a clinical comparative study of the Exablate Prostate system used to treat diseased prostate tissue. This study will evaluate the safety and efficacy of focal treatment using high intensity focused ultrasound when compared to active surveillance in men living with prostate cancer.

Industry News: New Study Shows DCT Methods Helped Lung Cancer Trial Enrollment as COVID Surged

Remote and flexible trial approaches have been a hallmark of clinical trials during the pandemic and are widely believed to have been the primary factor in keeping trials open and operating. There is evidence showing that such measures as telehealth visits, off-site diagnostic/monitoring procedures and remote consenting were at least partially responsible for the ability of lung cancer trials to weather the storm.

Positive Trial Data with 100% Safe Delivery

Moleculin Announces Positive Trial Data with 100% Safe Delivery of p-STAT3 Inhibitor and Efficacy in Majority of Patients

Preliminary results from phase 1 clinical trial of WP1220 for treatment of cutaneous T-cell lymphoma (“CTCL”); supports phase 2 study.

“For years, p-STAT3 (the activated form of STAT3) has been considered an ‘undruggable’ target because of the difficulty of reaching and affecting this cell-signaling protein,” commented Walter Klemp, Moleculin’s Chairman and CEO. “Some consider it to be a master regulator of cancer-related gene transcription, so we believe the ability to show a therapeutic effect from a p-STAT3 inhibitor could be considered a significant breakthrough in cancer research.”

Results: There were 6 patients screened, and 5 patients enrolled between March and July 2019. Three are evaluable for both safety and efficacy after completing 3 months of treatment, with 2 ongoing and evaluable for safety. The only AE reported potentially related to study drug in one of the five patients was a mild contact dermatitis not requiring treatment. CAILS scores on index lesions were significantly decreased in the first 3 patients, who were stages IA, IB, and IIB, respectively, at entry. A composite score was obtained for all treated lesions for each patient, and percent changes were calculated from baseline to Day 84. There was a median reduction of 70.8% (range 62.1%-76.2%) for the 3 patients. Improvement was noted as early as 7 days after initiation of treatment, and maintenance of improvement was also shown at follow up (1 month after discontinuation, as per protocol). The fourth patient has also shown an initial reduction in the composite CAILS score after 56 days (26.7%), and is continuing on treatment. Evaluations of the biopsy samples for histopathology and status of p-STAT3 in treated lesions are in progress.

Conclusions: WP1220, an inhibitor of p-STAT3, has shown demonstrable safety and significant efficacy after at least 3 months of topical treatment in 3 patients with progressive MF, with a continuing trend towards improvement in additional patients currently in treatment. This is the first demonstration that inhibition of the STAT3 activation pathway with topical therapy has impacted the course of this disease. The trial is continuing, and updated and more comprehensive data from this study as well as assessment of STAT3 phosphorylation in treated lesions will be reported.

“This is the first topical delivery of a p-STAT3 inhibitor that we know of for CTCL, where there is a significant unmet need for improved treatment of the lesions associated with this potentially deadly skin cancer. But, we believe the significance of this data goes well beyond CTCL, as it speaks to the targeting of p-STAT3 as a general strategy. We are excited to share these preliminary results in association with ASH, especially because we believe showing activity here could have exciting implications for the future of STAT3 inhibitors in general. Although this is a relatively small pilot study, we believe the results justify an expansion to a larger patient population in a Phase 2 clinical trial,” added Dr. Sandra Silberman, CMO at Moleculin.
