ClinConnect Summary

This clinical trial is studying a new oral medication called INX-315, which is being developed to treat advanced cancers, specifically hormone receptor-positive breast cancer and certain types of ovarian cancer. The trial aims to find out how safe the medication is, how well it works, and how the body processes it. It is for patients whose cancer has not responded to previous treatments, including those who have already tried other therapies. Participants may include individuals with advanced or metastatic breast or ovarian cancer that has progressed after treatment with certain other cancer drugs.

To be eligible for this trial, participants should have advanced breast cancer that is hormone receptor-positive and HER2-negative, or advanced ovarian cancer that has not responded to standard treatments. They should also have at least one measurable tumor that hasn't been treated with radiation. Throughout the study, participants can expect to take INX-315 daily and undergo regular check-ups to monitor their health and the effects of the drug. This trial is currently recruiting participants, and it's important for anyone considering joining to discuss it with their healthcare provider to ensure they meet the criteria and understand the potential risks and benefits.

  • 4. Have visceral crisis, lymphangitic spread, or leptomeningeal carcinomatosis.
  • 5. Have clinically active ongoing interstitial lung disease (ILD) of any etiology, including drug-induced ILD, and radiation pneumonitis within 28 days prior to initiation of study treatment.

  • 7. Uncontrolled, cardiovascular disease (including hypertension) with or without medication
  • 8. History of other malignancies, except for the following: (1) adequately treated basal or squamous cell carcinoma of the skin; (2) curatively treated a) in situ carcinoma of the uterine cervix, b) prostate cancer, or c) superficial bladder cancer; or (3) other curatively treated solid tumor with no evidence of disease for ≥ 3 years.
  • 9. Known HIV infection, including AIDS-related illness, or have active, uncontrolled infection (viral, bacterial, or fungal), including tuberculosis, hepatitis B virus, hepatitis C virus, or COVID-19 infection (symptoms and a positive test result).
  • 10. Requires treatment with a prohibited medication or herbal remedy that cannot be discontinued at least 2 weeks before the start of study drug administration.
  • 11. Have planned or anticipation of the need for major surgical procedure within 28 days of the first dose of study drug (procedures such as central venous catheter placement, tumor needle biopsy, and feeding tube placement are not considered major surgical procedures).
  • 12. Unwilling or unable to comply with scheduled visits, study drug administration plan, laboratory tests, or other study procedures and study restrictions.
  • 13. Radical radiotherapy within 28 days prior to study entry or palliative radiotherapy within 2 weeks prior to study entry.
  • 14. Systemic anti-cancer therapy within 28 days or at least 5 half-lives, whichever is less, prior to the first dose of the study drug
  • 15. Prior irradiation to \> 25% of the bone marrow
  • 16. Previous high-dose chemotherapy requiring prior stem cell transplant
  • 17. Participation in other studies involving investigational drug(s) within 4 weeks prior to study entry.
  • 18. Known or suspected hypersensitivity to active ingredient/excipients in INX-315 or fulvestrant or abemaciclib.
  • 19. Known difficulty in swallowing or tolerating oral medications, or conditions which would impair absorption of oral medications such as active inflammatory gastrointestinal disease, uncontrolled nausea or vomiting (i.e., CTCAE ≥ Grade 3 despite antiemetic therapy), ongoing gastrointestinal obstruction/motility disorder/active inflammation, malabsorption syndrome, chronic diarrhea, known diverticular disease or previous gastric resection or lap band surgery.
  • 20. Has a serious and/or uncontrolled pre-existing medical condition(s) that, in the judgment of the Investigator or the Sponsor, would preclude participation in this study (for example but not limited to, interstitial lung disease, severe dyspnea at rest or requiring oxygen therapy, history of major surgical resection involving the stomach or small bowel, or preexisting Crohn's disease or ulcerative colitis or a preexisting chronic condition resulting in baseline Grade 2 or higher diarrhea)
