IKS014 in Advanced Solid Tumors That Express HER2
December 15, 2023 updated by: Iksuda Therapeutics Ltd.
A Phase 1 Dose Escalation Trial to Determine the Safety, Tolerance, Maximum Tolerated Dose, and Preliminary Antineoplastic Activity of IKS014, a HER2-Targeting Antibody Drug Conjugate (ADC), in Participants With Advanced HER2+ Solid Tumors
This study will evaluate the recommended dose for further clinical development, safety, tolerability, anti-tumor activity, immunogenicity, pharmacokinetics and pharmacodynamics of IKS014, a HER2 targeting antibody-drug conjugate, in patients with advanced solid tumors.

Detailed Description
The study will consist of 2 parts: dose-escalation (Part 1) and dose-expansion (Part 2).
The dose-escalation part (Part 1) of the study is to evaluate the safety and tolerability of increasing dose levels of IKS014 to establish a recommended phase 2 dose (RP2D); and the dose-expansion part (Part 2) of the study is to further evaluate the safety, pharmacokinetics/pharmacodynamics, and efficacy of IKS014 at the RP2D.

- Total bilirubin ≤ 1.5 x ULN if no liver metastases or < 3 x ULN with Gilbert's Syndrome or liver metastases at baseline
- Albumin > 2.5 g/dL
- Prothrombin time or international normalized ratio (INR) and either partial thromboplastin time (PTT) or activated (a) PTT ≤ 1.5 x ULN, ≤ 3 x institutional ULN if anticoagulated.
- Must have adequate treatment washout period before trial treatment, defined as: Major surgery (≥ 4 weeks) and radiation therapy (≥ 3 weeks; in case of palliative radiation ≥ 2 weeks)
- Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1 (or equivalent Karnofsky PS)
Part 2 Dose Expansion Cohorts May Include:
- Advanced or metastatic BC that is confirmed HER2-positive defined as IHC 3+ or IHC 2+ and evidence of HER2 amplification by ISH, as per ASCO-CAP and previously treated with at least two HER2 directed treatments.
- Advanced or metastatic BC that has low HER2 expression defined as IHC2+ (ISH-) or IHC1+ (ISH-/+ or untested) and previously treated with at least 1 prior line of therapy which may include chemotherapy and/or a HER2 directed ADC.
- Advanced or metastatic GC or GEJ cancer that is confirmed HER2-positive defined as IHC 3+ or IHC 2+ and evidence of HER2 amplification by ISH as per ASCO-CAP and previously treated with at least 1 prior line of therapy, which may include chemotherapy and/or a HER2 directed ADC.
- Advanced or metastatic GC or GEJ cancer that has low HER2 expression defined as IHC2+ (ISH-) or IHC1+ (ISH-/+ or untested) and has been previously treated with at least one prior line of therapy.
- Advanced or metastatic solid tumor that has any degree of HER2 expression (HER2 IHC3+, IHC2+, IHC1+ or ISH+) or a known activating HER2 mutation and has been treated with standard of care therapy relevant to the disease.
Key Exclusion Criteria:
- History of (noninfectious) ILD/pneumonitis that required steroids, has current ILD/pneumonitis, or where suspected ILD/pneumonitis cannot be ruled out by imaging at Screening.
- Any clinically apparent ≥ Grade 2 pulmonary compromise resulting from intercurrent pulmonary illnesses including, but not limited to, any underlying pulmonary disorder (i.e., pulmonary emboli within three months of the trial enrollment, severe asthma, severe chronic obstructive pulmonary disease [COPD], restrictive lung disease, pleural effusion, etc.), and any autoimmune, connective tissue or inflammatory disorders with potential pulmonary involvement (e.g., rheumatoid arthritis, Sjogren's, sarcoidosis), or prior pneumonectomy.
- Current evidence of ≥ Grade 2 keratitis or other corneal abnormality.
- Evidence of a clinically significant (≥ Grade 2) abnormality on slit-lamp examination or other clinically significant ophthalmologic finding, as determined by an ophthalmologist.
