Rogaratinib in Patients With Advanced Pretreated Squamous-cell Non-small Cell Lung Cancer (SQCLC)

Inclusion Criteria:

* Written informed consent according to Swiss law and ICH-GCP regulations before registration and prior to any trial specific procedures including screening procedures. Informed consent for trial entry must be offered only after positive results of individual FGFR testing has been received.
* Histologically or cytologically confirmed diagnosis of locally advanced or metastatic NSCLC (from inoperable stage IIIB to stage IV according to the 8th edition of the American Joint Commission on Cancer TNM staging system) with squamous-cell or predominantly squamous-cell histology (referred to SQCLC).
* Archival or fresh tumor biopsy specimen for FGFR (subtypes 1-3) mRNA expression testing available. Acceptable samples include core needle biopsies for deep tumor tissue (minimum three cores) or excisional, incisional, punch, or forceps biopsies for cutaneous, subcutaneous, or mucosal lesions.
* High FGFR1-3 mRNA expression levels based on central analysis of archival or fresh tumor biopsy specimen (high expression defined as ≥ 1 FGFR isoform with RNAscope score of 3 or 4).
* Measurable or evaluable disease (according to RECIST v1.1). Previously irradiated lesions should not be counted as target lesions unless there has been demonstrated progression in the lesion since radiotherapy before enrolment and no other lesions are available for selection as target lesions.
* Patient failed standard systemic therapy for locally advanced or metastatic disease (1-3 prior chemotherapy regimens and at least 1 immune checkpoint inhibitor (combination allowed)).
* Patients with known brain metastases must have undergone definitive treatment (surgery and/or radiation) at least 2 weeks prior to registration and must be clinically stable (no requirement of steroids and no worsening neurological deficits for 2 weeks prior registration).
* Patients with a prior malignancy and treated with curative intention are eligible if treatment of that malignancy was completed at least 2 years before registration and the patient has no evidence of disease at registration. Less than 2 years is acceptable for malignancies with low risk of recurrence and/or no late recurrence.
* Known human immunodeficiency virus (HIV)-infected patients who are healthy and have a low risk of AIDS-related outcomes are eligible, if,

  * CD4+ T-cell counts are ≥ 350 cells/ųL
  * No history of AIDS-defining opportunistic infection within past 12 months
  * Patient agrees to concomitant antiretroviral therapy (ART) if not currently on ART, or is on ART for ˃ 4 weeks and has a HIV viral load ˂ 400 copies/mL.
* Age ≥ 18 years.
* WHO performance status 0-2.
* Adequate bone marrow function: absolute neutrophil count (ANC) ≥ 1.5 x 109/L1, platelet count ≥ 100 x 109/L2, hemoglobin ≥ 90 g/L2

  1. without granulocyte colony-stimulating factor support within 2 weeks before the first administration of trial treatment
  2. without transfusion or erythropoietin within 2 weeks before the first administration of trial treatment
* Adequate hepatic function: total bilirubin ≤ 1.5 x ULN (≤ 3 x ULN for patients with known Gilbert syndrome), ALT and AST ≤ 2.5 x ULN (≤ 5 x ULN for patients with liver involvement of their cancer).
* Adequate renal function: estimated glomerular filtration rate (eGFR) \> 30 mL/min/1.73m2 according to the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) abbreviated formula.
* Adequate pancreatic function: lipase ≤ 2 x ULN.
* Women with childbearing potential are using highly effective contraception, are not pregnant or lactating and agree not to become pregnant during trial treatment and during 5 months thereafter. A negative urine or serum pregnancy test before registration is required for all women with child-bearing potential.
* Men agree not to donate sperm or father a child. Men without a vasectomy and with a partner of childbearing potential must agree to use condoms during trial treatment and during 5 months thereafter.
* Patient is able and willing to swallow the trial IMP as whole tablet.
* Patient consents to the mandatory translational research projects with biopsied tumor material.

Exclusion Criteria:

* Symptomatic untreated brain metastases or leptomeningeal disease.
* Previous treatment with anti-FGFR directed therapies (e.g. receptor tyrosine kinase inhibitors including rogaratinib or FGFR-specific antibodies).
* Chemotherapy, or radiotherapy, or immunotherapy, or small molecule drugs within 3 weeks (1 week for palliative radiotherapy) prior to registration.
* Other investigational medicinal products within 4 weeks prior registration.
* Major surgery within 2 weeks prior registration.
* Concomitant use of other anti-cancer drugs or radiotherapy except for local pain control.
* Concomitant therapies that are known to increase serum phosphate levels (i.e. antacids, laxatives oral/rectal, oral phosphate binders, potassium phosphate) and that cannot be discontinued or switched to a different medication before trial entry.
* Use of strong inhibitors of CYP3A4 and strong inducers of CYP3A4 within 2 weeks prior registration or during trial treatment.
* History or current condition of an uncontrolled cardiovascular disease including any of the following conditions:

  * Congestive heart failure (CHF) NYHA Class 2 or greater, unstable angina (symptoms of angina at rest).
  * New-onset angina (within last 3 months prior registration).
  * Myocardial infarction (MI) within past 6 months prior registration.
  * Unstable cardiac arrhythmias requiring anti-arrhythmic therapy. Patients with arrhythmia not requiring therapy or under control with anti-arrhythmic therapy are eligible.
  * Patients with known coronary artery disease, congestive heart failure not meeting the above criteria, must be on a stable medical regimen that is optimized in the opinion of the treating physician, in consultation with a cardiologist if appropriate.
  * Symptomatic arterial hypotension.
* Current diagnosis of any retinal disorders including retinal detachment, retinal pigment epithelial detachment (RPED), serous retinopathy or retinal vein occlusion.
* Current evidence of endocrine alteration of calcium phosphate homeostasis (e.g. parathyroid disorder, history of parathyroidectomy, tumoral calcinosis, paraneoplastic hypercalcemia).
* Active chronic Hepatitis C or Hepatitis B Virus infection. Uncontrolled active systemic infection requiring intravenous (i.v.) antimicrobial treatment.
* Active tuberculosis.
* Seizure disorder requiring medication.
* Serious, non-healing wound, ulcer or bone fracture.
* Arterial or venous thrombotic events or embolic events such as cerebrovascular accident (including transient ischemic attacks), deep vein thrombosis or pulmonary embolism within 6 months prior registration.
* History of organ allograft.
* Any malabsorption condition.
* Previous drug- or procedure-related AE ≥G2 (according to CTCAE v5.0) at registration (exception: chronic kidney disease G2, or persistent alopecia of any grade, and/or anemia \[hemoglobin ≥ 90 g/L\] can be included).
* Any concomitant drugs contraindicated for use with the trial drug according to the IB.
* Known hypersensitivity to the trial drug, or to any component of the trial drug.
* Any other serious underlying medical, psychiatric, psychological, familial or geographical condition, which in the judgment of the investigator may interfere with the planned staging, treatment and follow-up, affect patient compliance or place the patient at high risk from treatment-related complication.
