- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Histologically-confirmed, primary, invasive breast cancer diagnosed within 5 years of study entry.
- Qualifying risk status, at diagnosis utilizing receptor testing by
- ASCO/CAP guidelines, meeting one of the following:

Show all 19Show fewer
- Evidence of residual disease in the breast on pathological assessment after neoadjuvant chemotherapy.
- Patients must have completed all primary therapy (definitive surgery, (neo)adjuvant chemotherapy adjuvant radiation and/or Her2-directed therapy) for the index malignancy at least 4 weeks prior to study entry. All prior treatment-related toxicity must be resolved prior to study enrollment. Concurrent receipt of adjuvant endocrine and bone modifying agents is allowed per standard of care guidelines.
- Bone marrow aspirate after completion of therapy demonstrates detectable DTCs (via IHC)
- No evidence of recurrent local or distant breast cancer by physical examination, blood tests (CBC, LFTs, Alk Phos), or symptom-directed imaging, per NCCN guidelines.
- Age ≥ 18 years
- ECOG performance status 2
- No contraindications to the study medications or uncontrolled medical illness.
- Adequate bone marrow function as shown by: ANC ≥ 1.5 x 109/L, Platelets ≥ 100 x 109/L, Hb >9 g/dL
- Adequate liver function as shown by: Serum bilirubin ≤ 1.5 x ULN, ALT and AST ≤ 2.5 x ULN, and INR ≤1.5
- Anticoagulation is allowed if target INR ≤ 1.5 on a stable dose of warfarin or on a stable dose of anticoagulant for >2 weeks at time of randomization. For patients on therapeutic anti-coagulants, medication must be clinically held peri-procedure (bone marrow aspirate) per standard clinical management.
- Adequate renal function: serum creatinine ≤ 2.0 x ULN or creatinine clearance (CrCl) ≥ 30mL/min obtained within 28 days prior to registration. A calculated creatinine clearance by Cockcroft-Gault Formula is acceptable in lieu of a measured value.

What is being measured
The primary outcome is the main question the study is designed to answer.
Feasibility: Number of Participants Who Completed 6 Cycles of Protocol Treatment Without Grade 3 or 4 Toxicity
For the primary endpoint of feasibility, we employed ongoing Bayesian toxicity monitoring after every 3 participants completed cycle 6, assuming a Beta (1,2) prior, equivalent to one DLT observed in 3 treated participants. Early termination of a treatment arm for toxicity (non-feasibility) would occur if the posterior probability that the toxicity rate exceeds the target maximum of 30% was greater than 75%. Trial enrollment and conduct was significantly impacted by the COVID pandemic, including shortage of HCQ and inability of enrolled patients to travel. To address this, we amended the protocol to allow study Arms C and D to be combined for feasibility assessment, given that the investigational treatment was the same in the two arms, enabling enrollment to be halted when the sample size needed for feasibility assessment was complete for all study treatments. Toxicity was assessed using CTCAE v4.0.
Measured: 3 years

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Hydroxychloroquine and Everolimus in people with Breast Cancer Stage IIB, run by Abramson Cancer Center at Penn Medicine at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 19 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 29 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 5 Mar 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Feasibility: Number of Participants Who Completed 6 Cycles of Protocol Treatment Without Grade 3 or 4 Toxicity (time frame: 3 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03032406, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jun 2026; AzTrials last refreshed its copy on 7 Nov 2026.
