Candel (CADL) Stock Skyrockets 431% Year to Date: Here's Why

In This Article:

Candel Therapeutics CADL, a clinical-stage oncology company, is focused on developing two novel therapeutics, CAN-2409 and CAN-3110, to treat a variety of cancer indications.

The company’s most advanced product candidate, CAN-2409, is an investigational adenovirus immunotherapy candidate that is being developed in separate mid to late-stage studies across three different types of cancer, including, prostate cancer, non-small cell lung cancer (NSCLC) and pancreatic cancer.

On the other hand, CAN-3110, Candel’s HSV-1-based immunotherapy candidate, is currently being evaluated in an ongoing investigator-sponsored early-stage study to treat recurrent high-grade glioma (HGG).

Year to date, shares of CADL have skyrocketed 430.6% against the industry’s 5.7% decline. Developmental and regulatory updates from the clinical program for CAN-2409 fueled the colossal stock price rally.

In April, Candel reported positive interim data from the phase II study evaluating CAN-2409 plus valacyclovir (prodrug), together with standard of care (SoC) chemoradiation, followed by resection for treating borderline resectable pancreatic ductal adenocarcinoma (PDAC).

The updated interim data from the ongoing phase II study showed that experimental treatment with CAN-2409 led to notable improvements in estimated median overall survival of 28.8 months compared with only 12.5 months in the control group in borderline resectable PDAC.

Patients treated with CAN-2409 had a survival rate of 71.4% compared with only 16.7% in the control group after chemoradiation at 24 months of treatment. Moreover, the survival rate was 47.6% for patients treated with CAN-2409 compared with a mere 16.7% in the control group at 36 months.

If successfully developed, CAN-2409 could present a significant commercial opportunity for Candel. There is a high unmet medical need for effective new treatments, given the frequent recurrence and short survival with SoC chemotherapy for non-metastatic PDAC.

Last week, Candel announced positive overall survival data from a phase II study evaluating CAN-2409 plusvalacyclovir, together with SoC in patients with stage III/IV NSCLCwho are non-responsive to immune checkpoint inhibitor therapy over a prolonged period.

Data from the study showed that treatment with two administrations of CAN-2409 plus valacyclovir led to a median overall survival of 20.6 months in NSCLC patients whose disease had progressed despite receiving prior anti-PD-(L)1 treatment. The median overall survival observed upon treatment with SoC docetaxel-based chemotherapy in a similar patient population was 11.6 months.
