Candel Therapeutics (NASDAQ:CADL): A Pioneer in Multimodal Biological Immunotherapies

Business Overview and History

Candel Therapeutics, a clinical-stage biopharmaceutical company, is at the forefront of developing innovative viral immunotherapies to help patients fight cancer. With a focus on harnessing the power of the immune system, Candel’s pipeline of product candidates, CAN-2409 and CAN-3110, aims to transform the treatment landscape for a variety of solid tumor indications.

Candel Therapeutics was incorporated in Delaware in June 2003 under the name Advantagene, Inc., with a focus on developing off-the-shelf viral immunotherapies to treat cancer. In December 2019, the company licensed substantially all the assets of Periphagen, a company focused on engineering herpes simplex virus (HSV) as a gene therapy vector. This acquisition expanded Candel’s pipeline to include HSV-based product candidates in addition to its adenovirus-based programs.

In September 2020, Candel licensed CAN-3110, an HSV-based oncolytic immunotherapy, from Mass General Brigham, adding a second clinical-stage program to its portfolio. Around this time, the company formally changed its name from Advantagene to Candel Therapeutics, Inc. to better reflect its focus on developing viral immunotherapies.

Candel completed its initial public offering in July 2021, raising $71.3 million to support the advancement of its pipeline. This included its lead adenovirus-based candidate CAN-2409, which was in late-stage clinical trials for prostate cancer, non-small cell lung cancer, and pancreatic cancer, as well as the HSV-based CAN-3110 which was in an early-stage trial for recurrent high-grade glioma.

Over the next few years, Candel faced several challenges, including the need to expand its manufacturing capabilities to support clinical development and potential commercialization. The company also encountered issues with its manufacturing processes, which required updating its stability testing program and submitting additional information to the FDA. Despite these obstacles, Candel was able to continue advancing its clinical programs and report positive data from studies of CAN-2409 in lung cancer and CAN-3110 in glioma.

Financial Snapshot

As of September 30, 2024, Candel Therapeutics reported cash and cash equivalents of $16.60 million. The company has not generated any revenue from product sales to date, as its lead product candidates are still in clinical development. For the nine months ended September 30, 2024, Candel reported a net loss of $41.10 million, compared to a net loss of $26.84 million for the same period in the prior year.

Candel has funded its operations primarily through the issuance and sale of its convertible preferred stock and common stock, as well as through debt financing. In February 2022, the company entered into a $25.00 million loan and security agreement with Silicon Valley Bank, of which it borrowed $20.00 million.

For the most recent fiscal year, Candel reported no revenue, a net loss of $37.94 million, operating cash flow (OCF) of -$34.24 million, and free cash flow (FCF) of -$34.70 million. In the most recent quarter, the company reported no revenue, a net loss of $10.65 million, and both OCF and FCF of -$6.57 million. Compared to the same quarter in the previous year, the net loss increased from $8.44 million, primarily due to an increase in the change in fair value of the warrant liability. The company’s OCF and FCF also decreased from the prior year quarter as Candel continues to incur expenses related to its clinical development programs.

Liquidity

Candel Therapeutics’ liquidity position remains a critical factor in its ability to continue operations and advance its clinical programs. With $16.60 million in cash and cash equivalents as of September 30, 2024, the company will likely need to secure additional funding to support its ongoing research and development activities. The company’s ability to raise capital through equity offerings, debt financings, or strategic collaborations will be crucial for its long-term sustainability and the advancement of its product candidates through clinical trials and potential commercialization.

As of September 30, 2024, Candel’s debt-to-equity ratio stood at -1.01, reflecting the company’s negative equity position due to accumulated losses. The company’s current ratio and quick ratio were both 1.18, indicating that it had sufficient short-term assets to cover its short-term liabilities. However, the company no longer has access to borrow the additional $5 million under its $25 million term loan facility with Silicon Valley Bank, as $20 million has already been drawn down.

Recent Developments and Highlights

In November 2023, Candel reported positive overall survival data from its phase 2 randomized controlled clinical trial of CAN-2409 in borderline resectable pancreatic cancer. The trial demonstrated a median overall survival of 28.8 months in the CAN-2409 treatment group compared to 12.5 months in the control group.

Furthermore, in May 2024, the company presented positive topline overall survival data from its phase 2 clinical trial of CAN-2409 in NSCLC patients who had an inadequate response to prior immune checkpoint inhibitor therapy. The data showed a median overall survival of 20.6 months following two administrations of CAN-2409 plus valacyclovir, compared to published results of 11.6 months with standard-of-care chemotherapy in a similar patient population.

Candel has also received Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) for both CAN-2409 and CAN-3110, for the treatment of pancreatic cancer and recurrent high-grade glioma, respectively. These designations provide Candel with certain development and commercial incentives, including the potential for up to seven years of market exclusivity in the United States if the products are approved.

In October 2022, Candel entered into a collaboration with the University of Pennsylvania (UPenn) Center for Cellular Immunotherapies to study the impact of novel viral immunotherapy candidates from Candel’s proprietary enLIGHTEN™ Discovery Platform on strengthening the activity of UPenn’s investigational CAR-T cell therapies in solid tumors.

In November 2023, Candel’s board of directors authorized a restructuring plan that resulted in a 45% reduction in the workforce. This was done to focus on key clinical readouts for CAN-2409 and the continued development of CAN-3110 and the enLIGHTEN platform. The restructuring plan was completed in Q1 2024.

On March 15, 2024, the company notified its former CEO and Chief Scientific Officer, Dr. Aguilar-Cordova, that it had uncovered issues related to falsified sterility testing results and an inadequate stability testing program for CAN-2409. The company promptly updated its stability testing program, submitted additional information to the FDA, and determined that trial participants were not placed at risk and the integrity of the clinical data was not impacted.
