Compugen (CGEN) has announced promising data on the triple combination of COM701, COM902, and pembrolizumab in treating platinum-resistant ovarian cancer patients. The data will be presented at the SITC 2024 conference in Houston, Texas. The study showed a 17.4% confirmed objective response rate and a 43.5% disease control rate in 23 evaluable patients.

The treatment demonstrated a favorable safety profile with mostly Grade 2 or lower adverse events, and only one Grade 3 event reported. Dr. Oladapo Yeku from Harvard Medical School highlighted the treatment's durability and effectiveness in late-stage ovarian cancer patients. The company plans to advance COM701 to earlier stages of ovarian cancer therapy, particularly targeting patients who are ineligible for maintenance treatment.

I dati saranno presentati alla conferenza SITC 2024 a Houston, Texas. Lo studio ha mostrato un tasso di risposta obiettiva confermato del 17,4% e un tasso di controllo della malattia del 43,5% in 23 pazienti valutabili.

Il trattamento ha dimostrato un profilo di sicurezza favorevole, con principalmente eventi avversi di Grado 2 o inferiori, e solo un evento di Grado 3 riportato. Il Dr. Oladapo Yeku della Harvard Medical School ha evidenziato la durata e l'efficacia del trattamento in pazienti con carcinoma ovarico in fase avanzata. L'azienda prevede di avanzare COM701 a fasi precedenti della terapia per il carcinoma ovarico, mirata in particolare a pazienti che non sono idonei per il trattamento di mantenimento.

Compugen (CGEN) hat vielversprechende Daten zur dreifachen Kombination von COM701, COM902 und Pembrolizumab bei der Behandlung von platinresistenten Ovarialkrebspatientinnen veröffentlicht. Die Daten werden auf der SITC 2024 Konferenz in Houston, Texas, vorgestellt. Die Studie zeigte eine bestätigte objektive Ansprechrate von 17,4% und eine Krankheitskontrollrate von 43,5% bei 23 auswertbaren Patientinnen.

Die Behandlung wies ein günstiges Sicherheitsprofil auf, mit hauptsächlich Grad 2 oder niedrigeren unerwünschten Ereignissen und nur einem berichteten Grad 3 Ereignis.

HOLON, ISRAEL, Nov. 5, 2024 /PRNewswire/ -- Compugen Ltd. (Nasdaq: CGEN) (TASE: CGEN) a clinical-stage cancer immunotherapy company and a pioneer in computational target discovery, today announced that data supporting the anti-tumor activity and safety profile of the triple combination COM701, COM902 and pembrolizumab in advanced heavily pre-treated patients with platinum resistant ovarian cancer (PROC) has been published as an abstract released by the Society for Immunotherapy of Cancer (SITC).

This data and additional clinical data will be presented by Oladapo Yeku, M.D., Ph.D., FACP, Assistant Professor of Medicine, Harvard Medical School, and Director of Translational Research, Gynecologic Oncology Program, Massachusetts General Hospital, Boston, MA, and an investigator in this study, as a poster presentation at the 39th Annual Meeting of SITC, taking place between November 8-10, 2024 in Houston, Texas.

"The data from this study along with data Compugen previously presented, demonstrate that COM701 is active, has a favorable safety profile, and is a differentiated immune checkpoint inhibitor. COM701 in combination with COM902 (Fc reduced anti-TIGIT) and pembrolizumab (anti-PD-1) resulted in durable objective responses in late-stage ovarian cancer patients typically not responsive to other immunotherapeutic agents," said Dr. Oladapo Yeku. "There is a significant unmet need for effective, durable, and tolerable treatment options for patients with relapsed ovarian cancer. I look forward to discussing this data in Houston at SITC on Friday, November 8, 2024 and participating in further clinical development of COM701."

Anat Cohen-Dayag, Ph.D. President, and Chief Executive Officer of Compugen added, "We are highly encouraged by the consistency of the data between our two platinum resistant ovarian cancer studies demonstrating COM701 driven activity and safety profile in more than forty advanced and heavily pre-treated patients. We believe these data support our initial observation of the unique mechanism of action of COM701 translating into clinical benefit in patients with ovarian cancer. We are encouraged by feedback from ovarian cancer experts supporting advancing COM701 to an earlier setting of ovarian cancer therapy based on its overall activity, safety profile and durability demonstrated in advanced disease. There is a gap in care for women with platinum sensitive ovarian cancer, who respond to chemotherapy but are ineligible for or cannot tolerate additional maintenance treatment. These patients have a less compromised immune system, providing the opportunity to harness the unique mechanism of action of COM701 to potentially change the disease trajectory improving progression free survival."

Dr. Cohen-Dayag continued, "Our development path in earlier lines of ovarian cancer will start by addressing this unmet need. I look forward to discussing these data and our future development plans including a fireside chat with Dr. Yeku, as part of our third quarter conference call that will take place on November 12, 2024, at 8:30 am ET."

The abstract is now available on the publication section of Compugen's website. The poster and short video presentation of the poster by Dr. Yeku will be available on the publication section of Compugen's website on Friday November 8, 2024.
