Reprogramming of breast tumor–associated macrophages with modulation of arginine metabolism

Article

Author: Sharma, Vandana ; Choi, Eun-Seok ; Fernando, Veani ; Furuta, Saori ; Sweef, Osama ; Zheng, Xunzhen

HER2+ breast tumors have abundant immune-suppressive cells, including M2-type tumor-associated macrophages (TAMs). Although TAMs consist of the immune-stimulatory M1 type and immune-suppressive M2 type, the M1/M2-TAM ratio is reduced in immune-suppressive tumors, contributing to their immunotherapy refractoriness. M1- versus M2-TAM formation depends on differential arginine metabolism, where M1-TAMs convert arginine to nitric oxide (NO) and M2-TAMs convert arginine to polyamines (PAs). We hypothesize that such distinct arginine metabolism in M1- versus M2-TAMs is attributed to different availability of BH4(NO synthase cofactor) and that its replenishment would reprogram M2-TAMs to M1-TAMs. Recently, we reported that sepiapterin (SEP), the endogenous BH4precursor, elevates the expression of M1-TAM markers within HER2+ tumors. Here, we show that SEP restores BH4levels in M2-like macrophages, which then redirects arginine metabolism to NO synthesis and converts M2 type to M1 type. The reprogrammed macrophages exhibit full-fledged capabilities of antigen presentation and induction of effector T cells to trigger immunogenic cell death of HER2+ cancer cells. This study substantiates the utility of SEP in the metabolic shift of the HER2+ breast tumor microenvironment as a novel immunotherapeutic strategy.

BACKGROUND:

Phenylketonuria is an inherited condition characterised by neurotoxic accumulation of phenylalanine (Phe). APHENITY assessed the efficacy and safety of orally administered synthetic sepiapterin in children and adults with phenylketonuria.

METHODS:

APHENITY was a phase 3, randomised, double-blind, placebo-controlled study performed at 34 clinics, hospitals, and university sites in 13 countries. Individuals of all ages with a clinical diagnosis of phenylketonuria were eligible for inclusion if they had a blood Phe concentration of 360 μmol/L or higher at study entry, whereas individuals with hyperphenylalaninaemia due to pathogenic variants in GCH1, PTS, QDPR, SPR, and PCBD1, consistent with a diagnosis of primary BH₄ deficiency, were excluded. Part 1 was a 14-day open-label assessment of blood Phe concentration response to sepiapterin. In part 2, sepiapterin-responsive participants were randomly assigned (1:1) by a web-response system based on a block randomisation schedule (permuted block size of 2 and 4) to 6 weeks of sepiapterin (forced-dose escalation: 20, 40, and 60 mg/kg per day per consecutive 2-week period) or placebo. The investigational drug and placebo were identical in their appearance and delivery. Dried blood samples were collected for analysis of Phe concentration on days -1, 1 (before dose was administered), 5, 10, 14, 19, 24, 28, 33, 38, and 42 in part 2, either in-clinic or at home. The primary endpoint for part 2, mean change from baseline in blood Phe after 6 weeks, was assessed in the primary analysis set of participants with at least a 30% reduction in blood Phe concentration in part 1, who took at least one dose in part 2. Safety was evaluated in all participants receiving at least one dose of treatment. The completed study is registered at EudraCT (2021-000474-29) and ClinicalTrials.gov (NCT05099640).

FINDINGS:

APHENITY was conducted between Sept 30, 2021, and April 3, 2023. 187 people were assessed for eligibility, of whom 157 were enrolled. In part 1, 156 participants were assessed or evaluated, of whom 114 (73%) were sepiapterin-responsive (ie, ≥15% reduction in blood Phe from baseline). In part 2, 98 participants (49 in the placebo group and 49 in the sepiapterin group) were in the primary analysis set. There was a significant reduction of blood Phe concentration after 6 weeks of sepiapterin (-63%, SD 20) compared with placebo (1%, 29; least squares mean change -395·9 μmol/L, SE 33·8; p<0·0001). Treatment-emergent adverse events were reported in 33 (59%) of 56 participants who received sepiapterin and 18 (33%) of 54 participants who received placebo. Most treatment-emergent adverse events were mild gastrointestinal events (11 [20%] of 56 participants who received sepiapterin and ten [19%] of 54 participants who received placebo) that resolved quickly. There were no deaths and no serious or severe adverse events.

INTERPRETATION:

Sepiapterin is a promising oral therapy for individuals with phenylketonuria, was well tolerated, and resulted in significant and clinically meaningful reductions in blood Phe concentration in participants with varying disease severity.

FDA approves PTC’s ultra-rare disease gene therapy for broader patient population than Europe

The FDA has cleared PTC Therapeutics’ gene therapy for AADC deficiency, an ultra-rare disease that impacts the nerve cells and brain. The gene therapy was granted an expansive label encompassing children and adults across “the full spectrum of disease severity,” according to PTC’s press release , and will be marketed as Kebilidi. Known generically as eladocagene exuparvovec, the gene therapy is marketed as Upstaza in the EU, UK and Israel, where it is indicated for children 18 months and older with severe AADC deficiency. It was first authorized in the EU and UK in 2022. In the UK, the therapy has a list price of about £3 million ($3.8 million). PTC has not yet disclosed the US list price for Kebilidi. In clinical trials with 26 patients, the therapy improved patients’ motor and cognitive function, according to results published in 2022 , with those improvements sustained for over five years in patients with long-term follow-up. In the US, it’s estimate d that fewer than 1,000 people have AADC deficiency. People with the genetic disease don’t make enough dopamine, which can result in developmental disabilities, sleep disorders, and motor and behavioral symptoms. Kebilidi is meant to increase dopamine production by introducing a functional copy of the DDC gene that is mutated in these patients. The gene therapy is administered directly to the brain and is the first such gene therapy to win approval in the US. Along with Kebilidi, PTC is waiting for FDA decisions for two other therapies it’s developing: Translarna, a Duchenne muscular dystrophy drug that was rejected in the US in 2016 and 2017 and is soon expected to lose its EU market authorization; and a PKU drug called sepiapterin.

In lupus, the immune system, meant to defend against infections, produces autoantibodies that mistake the body's own cells as foreign, causing other immune cells to attack organs such as the kidneys, brain, heart, lungs and skin, as well as blood and joints. Ninety percent of people with lupus are women, most often diagnosed between the ages of 15-45. Black, Latinx, Indigenous, Asian and Pacific Islander people are disproportionately affected by lupus and more likely to experience severe lupus symptoms.
