Brief Summary

The goal of this study is to evaluate the safety of the experimental drug, CUE-102, and establish the recommended dose of CUE-102 for participants with Recurrent Glioblastoma (GBM).

The name of the study drug involved in this study is:

-CUE-102 (a type of fusion protein)

Detailed Description

This is a single center, open-label, Phase Ib trial evaluating the safety and tolerability of CUE-102 monotherapy in adult participants with Glioblastoma (GBM) at first recurrence. CUE-102 is designed to target tumor cells by activating T cells, potentially improving clinical outcomes in recurrent GBM.

The U.S. Food and Drug Administration (FDA) has not approved CUE-102 as a treatment for Recurrent Glioblastoma.

The research study procedures include screening for eligibility, in-clinic visits, Computerized Tomography (CT) scans, Magnetic Resonance Imaging (MRI) scans, blood and urine tests, and electrocardiograms (ECG).

It is expected that about 18 people will take part in this research study.

Cue Biopharma, Inc. is supporting this research study by providing the study drug, CUE-102.

• Women of child-bearing potential (WOCBP), defined as all women physiologically capable of becoming pregnant, must have a negative urine or serum pregnancy within 72 hours prior to enrollment. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required;

--Women in the following categories are not considered WOCBP:

• Premenarchal
• Premenopausal female with 1 of the following:

• Documented hysterectomy
• Documented bilateral salpingectomy
• Documented bilateral oophorectomy
• Note: Documentation can come from the site personnel's review of the participant's medical records, medical examination, or medical history interview.
• Postmenopausal female

• A postmenopausal state is defined as no menses for 12 months without an alternative medical cause.

-----A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy (HRT). However, in the absence of 12 months of amenorrhea, confirmation with two FSH measurements in the postmenopausal range is required.

• Females on HRT and whose menopausal status is in doubt will be required to use one of the non-hormonal highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status before study enrollment.
• Women of child-bearing potential (WOCBP; see definition above), must agree to use a highly effective method of contraception consistently and correctly as described below during study treatment and for 120 days after study treatment discontinuation or the initiation of other cancer therapy (whichever is shorter);

• Highly Effective Contraceptive Methods That Are User Dependent a (Failure rate of < 1% per year when used consistently and correctly.)
• Combined (estrogen- and progestogen- containing) hormonal contraception

• i. Oral
• ii. Intravaginal
• iii. Transdermal
• iv. Injectable
• Progestogen-only hormonal contraception

• v. Oral
• vi. Injectable
• Highly Effective Methods That Have Low User Dependency (Failure rate of <1% per year when used consistently and correctly)

• Progestogen- only contraceptive implant
• Intrauterine hormone-releasing system (IUS) Intrauterine device (IUD)
• Bilateral tubal occlusion
• Vasectomized partner (A vasectomized partner is a highly effective contraception method provided that the partner is the sole male sexual partner of the WOCBP and the absence of sperm has been confirmed. If not, an additional highly effective method of contraception should be used).
• Sexual abstinence (Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatment. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the study and the preferred and usual lifestyle of the participant).
• NOTES: Use should be consistent with local regulations regarding the use of contraceptive methods for participants of clinical studies.

• a. Typical use failure rates are lower than perfect-use failure rates (i.e. when used consistently and correctly).
• b. If hormonal contraception efficacy is potentially decreased due to interaction with study treatment, condoms must be used in addition to the hormonal contraception during the treatment period and for at least during study treatment and for 120 days after study treatment discontinuation after the last dose of study treatment or the initiation of other cancer therapy (whichever is shorter).
• c. If locally required, in accordance with Clinical Trial Facilitation Group (CTFG) guidelines, acceptable contraceptive implants are limited to those which inhibit ovulation.
• Male participants must agree to use at least one of the following methods of contraception starting with the first dose of study therapy through 120 days after the last dose of therapy or the initiation of other cancer therapy (whichever is shorter):

• Be abstinent from penile-vaginal intercourse as their usual and preferred lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent
• Use a male condom plus partner use of a contraceptive method with a failure rate of <1% per year when having penile-vaginal intercourse with a woman of childbearing potential who is not currently pregnant.

• a. Note: Men with a pregnant or breastfeeding partner must agree to remain abstinent from penile-vaginal intercourse or use a male condom during each episode of penile penetration.
