MONT-SAINT-GUIBERT, Belgium--(BUSINESS WIRE)--Regulatory News:
Celyad (Euronext Brussels and Paris, and NASDAQ:CYAD) a clinical-stage biopharmaceutical company focused on the development of CAR-T cell therapies, today announced the successful injection of the first patients in the SHRINK trial and the LINK trial, both targeting metastatic colorectal patients.
Dr. Christian Homsy, CEO of Celyad commented: “The infusion of a first patient in a new trial is always an important moment. CYAD-01, concurrently administered with standard chemotherapy FOLFOX in SHRINK, or administered through hepatic transarterial injections in LINK appears to have been well–tolerated to date. We are particularly satisfied with the lack of on target/off tumor toxicity observed to date in the context of the combination of CYAD-01 with chemotherapy. This bolstered our belief that, based on a careful and exhaustive clinical development plan, our product candidate will lead the path towards a therapy for cancer patients.”
After the promising signals of clinical activity of CYAD-01 reported in 2017 and validation of the use of the NKG2D receptor, Celyad designed a clinical development plan which aims at defining the best of the following approaches for CYAD-01 in patients with Acute Myeloid Leukemia (AML) and colorectal (CRC) cancers:
- CYAD-01 as a stand-alone investigational therapy, currently being evaluated in the THINK trial with relapsed refractory AML and CRC patients. Results have already been reported: the world’s first complete response by a CAR-T cell therapy in a patient with refractory and relapsed AML as well as stable diseases reported in colorectal and ovarian cancer patients.
- CYAD-01 administered concurrently with standard of care treatments. The SHRINK trial was initiated with CRC patients earlier in 2018. We expect that the EPITHINK trial will be initiated soon with AML patients.
- CYAD-01 administered after preconditioning of the patients using lymphodepletion. We expect trials in AML (DEPLETHINK AML) and CRC (DEPLETHINK CRC) patients to be initiated in the coming weeks.
Our objective is to continue with the above approach that offers the best observed safety/efficacy profile and to move forward in later phase clinical trials in both AML and CRC indications.
Dr. Frédéric Lehmann, VP Clinical Development and Medical Affairs at Celyad added: “Today’s announcement reflects Celyad’s commitment to develop the potential of CYAD-01 and is the result of our strong collaborations with key academic institutions in both the USA and Europe. Our clinical strategy aims to build on the favorable tolerability profile of CYAD-01 observed to date, and evaluate CYAD-01 in multiple settings to find the best approach for cancer patients. We are making good progress and look forward to sharing further results on SHRINK, LINK and other trials.“
SHRINK is an open-label Phase I trial evaluating the safety and clinical activity of multiple doses of CYAD-01, administered concurrently with the neoadjuvant FOLFOX treatment in patients with resectable liver metastases from colorectal cancer. The dose escalation design of SHRINK includes three dose levels: 1x108, 3x108 and 1x109 of CYAD-01. At each dose, the patients will receive three successive administrations, two weeks apart at the specified dose. No adverse events have been reported in the first injection of the first patient enrolled.
LINK is an open-label Phase I trial evaluating the safety and clinical activity of CYAD-01, adopting a loco-regional approach in treating patients with multiple CYAD-01 administration through hepatic transarterial injections to colorectal cancer patients diagnosed with unresectable liver metastases. The dose escalation design of LINK includes three dose levels: 3x108, 1x109 and 3x109 of CYAD-01. At each dose, the patients will receive three successive administrations, two weeks apart at the specified dose. No adverse events have been reported in the first patient enrolled, who has received his three consecutive CYAD-01 administrations.
