- Has received radioimmunoconjugates or toxin conjugates within 12 weeks before the first dose of study treatment.
Has had received prior systemic anticancer therapy, or targeted small molecule therapy, or definitive radiotherapy ≤28 days (14 days for palliative radiation) prior to the first dose of study treatment.
Note: Patients must have recovered from all AEs due to previous therapies to ≤Grade 1 or baseline. Patients with ≤Grade 2 alopecia may be eligible.
Note: Patients must have recovered from all radiation-related toxicities.
Has undergone major surgery (excluding lymph node biopsy) or significant trauma ≤4 weeks before the first dose of study treatment.
Note: patients must have recovered adequately from the toxicity and/or complications from the treatment prior to starting study treatment.
- Has had autologous stem cell transplant within 6 months prior to first dose of study treatment, or prior allograft stem cell transplantation at any time.
- Use of medications or foods that are moderate cytochrome P (CYP)3A inhibitors, strong or moderate CYP3A inducers within 14 days prior to first dose of study treatment or 5 half-lives of the given drug, whichever is longer.
- Has a history of immunodeficiency or has received systemic steroids (in dosing exceeding 10 mg daily of prednisolone equivalent) or any other form of immunosuppressive therapy within 7 days of the first dose of study treatment. The use of physiological doses of corticosteroids may be approved after consultation with the Sponsor.
- Has received a live vaccination within 4 weeks before the first dose of study treatment. Examples of live vaccines include but are not limited to the following: measles, mumps, rubella, varicella/zoster, yellow fever, Bacille Calmette-Guérin (BCG) and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g., FluMist®) are live attenuated vaccines and are not allowed.
Has received granulocyte colony-stimulating factor or blood transfusion within 7 days before start of screening.
Prior/Concurrent Clinical Study Experience
Is currently participating in or has participated in a study with an investigational compound or device within ≤4 weeks prior to the first dose of study treatment.
Note: Patients who have entered the follow-up phase of an investigational study may participate so long as it has been at least 4 weeks since the last dose of the previous investigational agent.
Diagnostic Assessments
- Has a known history of or newly diagnosed infection with HIV, Hepatitis B (defined as HBsAg reactive) or hepatitis C virus (HCV) (defined as detection of qualitative HCV virus RNA).
Has a history or current evidence of any condition, laboratory abnormality or other circumstances that might confound the results of the study or interfere with participation for the full duration of the study, such that it is not in the best interests of the patient to take part in the study.
Other Exclusions
- Patient is pregnant or breastfeeding or expecting to conceive of father children for the duration of the study.
- Has a history of hypersensitivity to YY-20394 and/or any excipients.
- Has a history of hypersensitivity to radiological imaging contrasting agents.
- Has a known psychiatric disorder that would interfere with proper cooperation with the requirements of the study.
- Is a regular user of illicit or recreational drugs or has had a recent history (within the last year) of drug or alcohol abuse of dependence.

Experimental: YY-20394
YY-20394 is a selective inhibitor of the delta isoform of phosphatidylinositol 3 kinase (PI3K-δ) which differs structurally from idelalisib, a PI3K-δ inhibitor approved for patients with relapsed chronic lymphocytic leukemia and indolent lymphoma.

YY-20394 is a selective inhibitor of the delta isoform of phosphatidylinositol 3 kinase (PI3K-δ) which differs structurally from idelalisib, a PI3K-δ inhibitor approved for patients with relapsed chronic lymphocytic leukemia and indolent lymphoma.
PI3K-δ signaling pathways are frequently hyperactive in B-cell cancers, making inhibition of PI3K-δ a promising target for B-cell malignancies.
YY 20394 has high potency against PI3K-δ, but with markedly improved selectivity in in vitro assays compared to idelalisib.
This higher selectivity for PI3K-δ may decrease the risk of serious infection seen with idelalisib and duvelisib (a PI3K-γ/δ dual inhibitor) due to strong immune suppression.
