9-ING-41 Plus Carboplatin in Salivary Gland Carcinoma

This trial is investigating an intravenous (IV) medication called 9-ING-41 in combination with chemotherapy (carboplatin) for the treatment of advanced salivary gland cancers.

The names of the study drug(s) involved in this study are:

* 9-ING-41 (a GSK-3β inhibitor)
* Carboplatin chemotherapy

This is a phase 2, open-label, non-randomized, single institution study investigating the novel glycogen synthase kinase-3 beta (GSK-3β) inhibitor 9-ING-41 in combination with carboplatin chemotherapy in patients with incurable, recurrent or metastatic salivary gland carcinomas (SGC).

The U.S. Food and Drug Administration (FDA) has not approved 9-ING-41 as a treatment for any disease. Carboplatin is used as a treatment for salivary gland cancers, and is approved by the FDA for many cancer types.

9-ING-41 has been identified in other studies as a therapy to block the over-expression of the glycogen synthase kinase-3 beta (GSK-3β) protein, which is thought to be important in signaling cancer growth and to have immune properties. It is believed that GSK-3β is over-expressed in salivary gland cancers and by blocking the action of GSK-3β protein with 9-ING-41 it could slow salivary cancer cell growth that have developed resistance to prior chemotherapy exposure.

The research study procedures include screening for eligibility and study treatment including evaluations and follow-up visits roughly every 3-weeks while on therapy, for up to one year as long as disease does not get worse and the drug therapy remains safe and tolerable.

It is expected that about 33 people treated will take part in this research study.

Actuate Therapeutics is supporting this research study by providing the study drug (9-ING-41) and funding some of the logistics of the trial that are beyond what would be considered standard of care.

Eligibility Criteria:
Inclusion Criteria:

* Participants must have histologically confirmed salivary gland carcinoma (any histologic subtype, including ACC) with evidence of recurrent, metastatic or advanced, unresectable disease.
* Willing to provide tumor tissue from a diagnostic biopsy or prior surgery.
* Age 18 years or older
* ECOG performance status 0-2 (see Appendix A)
* Participant must have organ and marrow function as defined below within 14 days prior to study registration:

  * leukocytes ≥ 3,000/mcL
  * absolute neutrophil count ≥ 500/mcL
  * hemoglobin ≥ 8.5 g/dL
  * platelets ≥ 75,000/mcL
  * total bilirubin ≤ 2.0 g/dL
  * AST(SGOT)/ALT(SGPT) ≤ 2.5× institutional upper limit of normal
  * creatinine within normal institutional limits OR
  * creatinine clearance ≥50 mL/min/1.73 m2 for participants with creatinine levels above institutional normal
* Participants must have documentation of a new or progressive lesion on a radiologic imaging study performed within 12 months prior to study registration (progression of disease over any interval is allowed) and/or new or worsening disease-related symptoms within 12 months prior to study registration. This assessment is performed by the treating investigator. Evidence of progression by RECIST v1.1 criteria not required.
* Participants must have at least one RECIST v1.1 measurable non-CNS based lesion, as defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) ≥ 1 cm with CT scans or MR imaging.
* Prior systemic therapy: At least 2 weeks must have elapsed since the end of prior chemotherapy, biological agents (3 weeks for anti-cancer monoclonal antibody containing regimens) or any investigational drug product, with adequate recovery of treatment-related toxicity to NCI CTCAE Version 5.0 grade ≤1 (or tolerable grade 2) or back to baseline (except for alopecia or neuropathy). Any number of prior therapies for recurrent/metastatic SGC are permitted (including prior carboplatin exposure); but prior therapy for recurrent/metastatic SGC is not required for participation.
* Ability to understand and the willingness to sign a written informed consent document.

Female subjects of childbearing potential should have a negative urine or serum pregnancy test within 14 days of study registration. Female subjects of childbearing potential should have a negative urine or serum pregnancy test repeated within 72 hours prior to receiving the first dose of study medication. WOCBP will be instructed to adhere to contraception for a period of 90 days after the last dose of investigational product. "Women of childbearing potential (WOCBP)" is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) or who is not postmenopausal. Menopause is defined clinically as 12 months of amenorrhea in a woman over 45 in the absence of other biological or physiological causes. In addition, women under the age of 55 must have a documented serum follicle stimulating hormone (FSH) level greater than 40 mIU/mL.

* Men who are sexually active with WOCBP must agree to use any contraceptive method with a failure rate of less than 1% per year. Men who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 90 days after the last dose of investigational product. Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile as well as azoospermic men) do not require contraception. See Appendix B for further guidance on contraception.

Exclusion Criteria:

* Metastatic disease impinging on the spinal cord or threatening spinal cord compression. Patients that have had previous treatment of disease with impinging on the cord with either surgery or radiotherapy with clinical or radiographic evidence of response or stability are eligible.
* Participant has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment), and have no evidence of new or enlarging brain metastases.
* Concurrent administration of other cancer specific therapy or investigational agents during the course of this study is not allowed.
* Patients on anticoagulants that require INR monitoring (such as warfarin).
* Uncontrolled intercurrent illness including but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, or cardiac arrhythmia.
* Pregnant or lactating women.
* Has a known additional malignancy that is progressing or requires active treatment. Exceptions include: basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer, and low-risk prostate adenocarcinoma being managed with active surveillance. A history of another separate malignancy in remission without evidence of active disease in the last 2 ears is permitted.
