Detailed Description:
Study TSC-007 is a prospective phase 2, open-label, multi-institutional basket trial to determine the efficacy and safety profile of nab-sirolimus administered to patients with malignant solid tumors harboring pathogenic inactivating alterations in TSC1 or TSC2 genes.

  4. Progression-free survival [ Time Frame: 9 months ]
    Number of months from study treatment initiation to the date of disease progression (by IRR) or death due to any cause

  5. Overall survival [ Time Frame: 24 months ]
    Number of months from study treatment initiation to the date of death due to any cause

  6. Patient-reported outcome [ Time Frame: 9 months ]
    Changes from baseline in the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire v3.0 (EORTC-QOQ-C30) scores

Layout table for eligibility information
Ages Eligible for Study:   12 Years and older   (Child, Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Patients must have a malignant solid tumor with a pathogenic inactivating TSC1 or TSC2 alteration. Genetic alterations should be identified using NGS in tumor tissue or liquid biopsy).

    • Patients will be enrolled after the central evaluation of NGS report confirms eligibility.

  2. Patients must have solid tumors that are metastatic or locally advanced where surgical resection is not an option or likely to result in severe morbidity.
  3. Patients must have received all standard therapies appropriate for their tumor type and stage of disease or, in the opinion of the Investigator, the patient would be unlikely to tolerate or derive clinically meaningful benefit from appropriate standard of care therapy, or the patient has no satisfactory alternative treatments.
  4. Patients must have 1 or more measurable target lesions by computed tomography (CT) scan or magnetic resonance imaging (MRI) (RECIST v1.1).
  5. Age: 12 years or older.
  6. Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 or Karnofsky Performance Status (KPS) ≥80 or Lansky play-performance scale for pediatric patients ≥80.

  7. Adequate liver function:

    1. Total bilirubin ≤1.5 × upper limit of normal (ULN) (unless due to Gilbert's syndrome, then ≤3 × ULN)
    2. Aspartate aminotransferase (AST) ≤2.5 × ULN (≤5 × ULN if attributable to liver metastases)
  8. Adequate renal function: creatinine clearance ≥30 mL/min, Cockcroft-Gault CCr = ((140-age) × weight[kg]) / (72 × SCr[mL/min]) × 0.85, if female

  9. Adequate hematologic parameters:

    1. Absolute neutrophil count (ANC) ≥1.0 × 109/L (growth factor support allowed)

    1. Females of childbearing potential must agree to use effective contraception or abstinence without interruption from 28 days prior to starting investigational product (IP) throughout 3 months after last dose of IP and have a negative serum pregnancy test (beta human chorionic gonadotropin, β-hCG) result at screening and agree to ongoing pregnancy testing during the course of the study, and after the end of study treatment. A second form of birth control is required even if she has had a tubal ligation.
    2. Male patients must agree not to donate sperm and must practice abstinence or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential while participating in the study and throughout 3 months after last dose of IP.

    1. Patients with meningeal carcinomatosis, leptomeningeal carcinomatosis, spinal cord compression, untreated brain metastases or symptomatic or unstable brain metastases. Note: Patients with stable brain metastases (defined as asymptomatic or no requirement for high-dose [defined as dexamethasone 10 mg daily or higher] or increasing dose of systemic corticosteroids) and without imminent need of radiation therapy are eligible. If applicable, patients must have completed brain radiation therapy and recovered adequately from any associated toxicity and/or complications prior to eligibility assessment. For patients who have received prior radiation therapy, post-treatment MRI scan should show no increase in brain lesion size/volume.

    4. Nonmalignant medical illnesses that are uncontrolled or whose control may be jeopardized by the treatment with the study therapy.
    5. A history of malignancies other than the one under treatment unless the patient is disease-free for more than 5 years from diagnosis. Note, controlled non-melanoma skin cancers, carcinoma in situ of the cervix, resected incidental prostate cancer, certain low grade hematologic malignancies (eg CLL, follicular lymphoma, etc), or other adequately treated carcinoma-in-situ may be eligible, after discussion with the medical monitor.

    7. Patients with history of interstitial lung disease and/or pneumonitis, or pulmonary hypertension.
    8. Individuals with known human immunodeficiency virus (HIV) infection are excluded from this study as combination antiretroviral therapy could potentially result in significant pharmacokinetic interactions. In addition, these individuals are at increased risk of serious infections due to the immunosuppressive effects of mTOR inhibition.
    9. Active Hepatitis B or Hepatitis C, with detectable viral load.
  5. Regarding concomitant medications with significant CYP3A4 and P-gp interactions, discontinuation of strong inhibitors (eg, ketoconazole, itraconazole, voriconazole, erythromycin, clarithromycin, telithromycin, and others), strong inducers (eg, rifampin, rifabutin), and known CYP3A4 substrates with a narrow therapeutic window (eg, fentanyl, alfentanil, astemizole, cisapride, dihydroergotamine, pimozide, quinidine, or terfenadine) is required at least 5 half lives prior to receiving the first dose of nab-sirolimus, whichever is longer.
