ArmTypeDescription
Group 1: Single Agent Dose EscalationEXPERIMENTALDose escalation phase to explore maximum tolerated dose of SY-5609 given as a single agent.
Group 2: SY-5609 + FulvestrantEXPERIMENTALParticipants with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2) negative advanced or metastatic breast cancer (BC) that has progressed following prior treatment with a cyclin-dependent kinase (CDK)4/6 inhibitor in combination with hormonal therapy will receive SY-5609 in combination with fulvestrant.
Group 3: SY-5609 + GemcitabineEXPERIMENTALParticipants with PDAC will receive SY-5609 in combination with gemcitabine in Safety Lead-in to identify a recommended combination dose for the expansion. The expansion part will assess the safety, tolerability, and preliminary clinical activity of SY-5609 in combination with gemcitabine at the recommended combination dose.
Group 4: SY-5609 + Gemcitabine + Nab-paclitaxelEXPERIMENTALParticipants with PDAC will receive SY-5609 in combination with gemcitabine plus nab-paclitaxel in Safety Lead-in to identify a recommended combination dose for the expansion. The expansion part will assess the safety, tolerability, and preliminary clinical activity of SY-5609 in combination with gemcitabine plus nab-paclitaxel at the recommended combination dose.

Frequently asked questions about SY-5609

What is SY-5609 used for?

SY-5609 is an investigational small molecule being studied for the treatment of advanced solid tumors, including breast cancer, small-cell lung cancer, and pancreatic cancer. It is being developed by Syros Pharmaceuticals, Inc. (NASDAQ: SYRS) and is currently in Phase 1 clinical development.

What does SY-5609 target?

SY-5609 is a selective CDK7 inhibitor. It targets cyclin-dependent kinase 7 (CDK7), a key regulator of cell cycle progression and transcription. By inhibiting CDK7, SY-5609 aims to disrupt tumor cell growth in advanced solid tumors.

Who is developing SY-5609?

SY-5609 is being developed by Syros Pharmaceuticals, Inc., a biopharmaceutical company traded on NASDAQ under the ticker SYRS. The company is conducting clinical research to evaluate the drug's safety and efficacy in patients with advanced solid tumors.

What phase is SY-5609 in?

SY-5609 is in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA. A Phase 1 study of SY-5609 in advanced solid tumors has been completed, with results expected to inform further development.

What clinical trials is SY-5609 in?

SY-5609 has been studied in a Phase 1 clinical trial with the identifier NCT04247126, titled "A Study of SY 5609, a Selective CDK7 Inhibitor, in Advanced Solid Tumors." This trial enrolled 105 participants with advanced solid tumors, breast cancer, small-cell lung cancer, and pancreatic cancer in the United States.

Is SY-5609 the same as SY 5609?

Yes, SY-5609 is also referred to as SY 5609 in clinical trial documentation. The drug is a selective CDK7 inhibitor being developed by Syros Pharmaceuticals for the treatment of advanced solid tumors.
