ADC Therapeutics announces Zynlonta data, $105M stock offering

ADC Therapeutics has announced it is undertaking a $105 million offering following what it describes as favorable topline results from a Phase 2 clinical trial of its cancer medication, Zynlonta. The Swiss biotechnology company plans to sell 13.4 million shares at $4.90 each, along with pre-funded warrants for an additional 8.1 million shares at $4.81 each to select investors. This announcement led to an approximate 8% dip in its stock price, listed under the ticker $ADCT, on Monday afternoon.

The company highlighted that its antibody-drug conjugate, Zynlonta, demonstrated a “high response rate” in patients suffering from relapsed or refractory marginal zone lymphoma (MZL). MZL is a relatively rare subtype of non-Hodgkin lymphoma, characterized by limited treatment options. Current treatments for MZL can include chemotherapy, immunotherapy, surgical intervention, or the use of Rituxan, a monoclonal antibody.

ADC Therapeutics' Chief Medical Officer, Mohamed Zaki, expressed optimism in a statement, noting that the company is considering seeking approval for the drug to treat MZL if the trial results continue to show promise. This indicates the company's commitment to advancing Zynlonta as a therapeutic option for patients with this challenging condition.

The recent developments surrounding Zynlonta and the subsequent capital raise reflect ADC Therapeutics' strategic efforts to propel its clinical and commercial objectives forward. The company’s focus on antibody-drug conjugates represents a cutting-edge approach in the field of oncology, aiming to deliver targeted cancer therapies that can improve patient outcomes while minimizing side effects.

In summary, ADC Therapeutics is pushing forward with a significant financial initiative in light of encouraging Phase 2 trial results for its cancer drug, Zynlonta. This step underscores the biotechnology firm's ongoing commitment to developing advanced treatments for cancer patients, particularly those with rare and difficult-to-treat conditions like marginal zone lymphoma. The outcome of these endeavors will be closely watched as the company aims to further validate and potentially expand the use of Zynlonta in clinical settings.
