A Phase 1b Trial of ATRC-101 in Adults With Advanced Solid Malignancies

Study Purpose

ATRC-101-A01 is a Phase 1b, open-label dose escalation and expansion trial of ATRC-101, an engineered fully human immunoglobulin G, subclass 1 (IgG1) antibody derived from a naturally occurring human antibody. The safety, tolerability, PK, and biological activity of ATRC-101 will be characterized when administered every two weeks (Q2W) or every 3 weeks (Q3W) as a monotherapy or in combination with other anticancer agents.

Recruitment Criteria

Replication-incompetent viral, mRNA, subunit, conjugate, and toxoid vaccines are allowed.
  • - COVID-19 (SARS-CoV-2) pandemic consideration: The COVID-19 vaccination should not be delayed; however, caution should be exercised when combining vaccination with cancer therapy, particularly immunotherapy.
The COVID-19 vaccines can cause transient lymphadenopathy and potentially impact assessment of disease burden during screening and/or on-study. To allow correct interpretation and reduce equivocal findings, investigators should discuss with the participant appropriate timing and selection of anatomic site of vaccination (alternative) with respect to imaging scans (MRI or CT). Screening scans should be acquired before the first dose of a COVID-19 vaccine or 4-6 weeks after the second dose of the vaccine. Because cancer patients are considered vulnerable population, after COVID-19 vaccination there is also a potential for heightened immune related adverse events including CRS. Investigators should use judgement when evaluating and managing potentially overlapping adverse events and in establishing causality with the study treatment (Schönrich and Raftery 2019; Desai et al. 2021; Edmonds et al. 2021; Indini et al. 2021) For the pembrolizumab combination therapy cohort ONLY:
  • - Experienced ≥ Grade 3 immune related adverse events while on immunotherapy prior to enrollment.
  • - Have not recovered from Grade 2 immune related adverse events attributed to immunotherapy to Grade 1 or baseline prior to enrollment.
  • - NSCLC with epidermal growth factor receptor (EGFR) or anaplastic lymphoma receptor tyrosine kinase (ALK) genomic tumor alterations.

5.0 ≥ Grade 3) or supplemental oxygen used to maintain adequate oxygenation within 14 days prior to the planned first dose of investigational product.
  • - Ongoing immune-related toxicity or immune-related toxicity requiring systemic corticosteroids for 30 or more consecutive days for a prior immune related adverse event before initiation of study treatment.
For the PLD combination therapy cohort ONLY: •Prior drug-induced cardiotoxicity, defined as a sustained decrease in the ejection fraction (EF) of > 15%.

Interventions

Biological: - ATRC-101

ATRC-101 is an engineered, fully-human IgG1 antibody derived from a naturally-occurring human antibody.

Biological: - Pembrolizumab

Pembrolizumab (Keytruda®) is a humanized immunoglobulin G4 monoclonal antibody with high specificity of binding to the programmed cell death 1 (PD-1) receptor, thus inhibiting its interaction with programmed cell death ligand 1 (PD-L1) and programmed cell death ligand 2 (PD-L2).

Drug: - Pegylated liposomal doxorubicin (PLD)

Pegylated liposomal doxorubicin (PLD) is doxorubicin hydrochloride (HCl), an anthracycline topoisomerase inhibitor that can bind DNA and inhibit nucleic acid synthesis. PLD is doxorubicin HCL encapsulated in liposomes formulated with surface-bound methoxypolyethylene glycol
