a dose escalation/expansion study of eras-601 in patients with advanced or metastatic solid tumors

Conditions: Advanced or Metastatic Solid Tumors

Summary: * to evaluate the safety and tolerability of escalating doses of eras-601 when administered as a monotherapy and in combination with other cancer therapies in study participants with advanced or metastatic solid tumors. * to determine the maximum tolerated dose (mtd) and/or recommended dose (rd) of eras-601 when administered as a monotherapy and in combination with other cancer therapies. * to characterize the pharmacokinetic (pk) profile of eras-601 when administered as a monotherapy and in combination with other cancer therapies. * to evaluate the antitumor activity of eras-601 when administered as a monotherapy and in combination with other cancer therapies.

this is a first-in-human, phase 1/1b, open-label, multicenter clinical study of eras-601 as a monotherapy and in combination with other cancer therapies. the study will commence with dose escalation of eras-601 monotherapy, followed by dose escalation of eras-601 in combination with other cancer therapies. once the monotherapy mtd and/or rd has been determined, then dose expansion of eras-601 monotherapy may commence with enrollment of study participants with advanced or metastatic solid tumors harboring specific molecular alterations. once the combination therapy mtd and/or rd has been determined, then dose expansion of that combination may commence with enrollment of study participants with advanced or metastatic solid tumors harboring specific molecular alterations.

Eligibility criteria:
inclusion criteria: * age ≥ 18 years * willing and able to give written informed consent * have histologically or cytologically confirmed advanced or metastatic solid tumor * there is no available standard systemic therapy available for the patient's tumor histology and/or molecular biomarker profile; or standard therapy is intolerable, not effective, or not accessible; or patient has refused standard therapy * able to swallow oral medication * have eastern cooperative oncology group performance status (ecog ps) of 0 or 1 * adequate cardiovascular, hematological, liver, and renal function * willing to comply with all protocol-required visits, assessments, and procedures exclusion criteria: * previous treatment with a shp2 inhibitor * documented ptpn11 mutations * is currently receiving another study therapy or has participated in a study of an investigational agent and received study therapy within 4 weeks of the first dose of eras-601 * received prior palliative radiation within 7 days of cycle 1, day 1 * have primary central nervous system (cns) disease or known active cns metastases and/or carcinomatous meningitis * prior surgery (e.g., gastric bypass surgery, gastrectomy) or gastrointestinal dysfunction (e.g., crohn's disease, ulcerative colitis, short gut syndrome) that may affect drug absorption * active, clinically significant interstitial lung disease or pneumonitis * history of thromboembolic or cerebrovascular events ≤ 12 weeks prior to the first dose of study treatment * history or current evidence of retinal vein occlusion (rvo) or current risk factors for rvo * have any underlying medical condition, psychiatric condition, or social situation that, in the opinion of the investigator, would compromise study administration as per protocol or compromise the assessment of aes * are pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the trial
